AV Geeks Lunch 3-17

all right there we go sorry technology i was trying to use obs to do something else last night and it didn't work and then it just kind of threw a wrench into everything uh welcome everybody santa paula signing off for now all right there we go all right as i said throwing the wrench into everything i'm skip alzheimer welcome to the av geeks lunchtime streaming show my calendar tells me that it is st patrick's day and i was woefully unprepared i'm not wearing anything green i don't have anything pulled uh about cabbage corned beef snakes st patrick ireland uh nothing the only thing that i could potentially show you would be i think a relatively offensive film about potato chips featuring leprechauns um so i don't know if i if i want to do that plus i've already shown it it's so good um anyways that last film was saint paula in 1929 it was a silent film and it was shot uh paid for by the chamber of commerce as a way to show how great sam santa paula was uh maybe locate your business here uh maybe you should move here etc um all right so i've got uh lots of films lined up to show uh this next one is i have it actually on the telecini 16 millimeter film and i have not seen this but it features puppets so i'm just going to tell you beware the puppets and um mild celebrity uh impersonations let me see there was at least one that i was like i think that i know that that voice is supposed to be so here we go i look at you [Music] [Music] [Music] hello i'm webster and what i would like to talk about today is you ouch why don't you look where you're going orson can't you see anything see yes c if you had used your eyes to see you wouldn't go around bumping into everyone what are eyes webster i was just about to show the children when you bumped into me see orson these are eyes most people use their eyes to see where they're going eyes come in different colors some eyes are a blue color some eyes are a brown color and some eyes are a green color eyes please show us what you see [Music] [Music] now let's play a game tell me what your eyes see [Music] watch out horses wow what was that orson didn't you see the train coming or hear it with your ears ears these are ears if you use them they will let you know about different sounds i guess if i had used my ears to listen i wouldn't have been run over certainly that's what ears are for to hear use your ears to listen and tell me what you hear so [Music] bye one [Music] [Applause] [Music] oh [Music] orson why didn't you leave didn't you see or hear the fire engine yes didn't you smell the smoke smell yes smell with your nose nose this is your nose it can warn you of dangerous odors your nose can also be used to smell nice things like popcorn flowers grass donuts and fudge mmm thinking about all those nice smells is making me hungry which brings us to the next member of our face what is that webster a mouth it looks funny what does it do i don't think i look funny and i do many things i open and close and talk and eat frown and smile and also i have a ton that i taste with teeth that i bite with what color are teeth white if you brush them see brush yes you should always brush your teeth after you eat especially after you eat candy i don't eat candy i do i also eat hamburgers ice cream apples cookies pickles and potato chips after all that you should brush your teeth all right puppy you're starting to make me mad i may say something i don't want to say to you now let's not argue excuse me i think i will say goodbye goodbye mouth orson you must learn to get along with others what's next now we come to an often unruly member of this group what is that that is hair what does hair do sometimes hair stands up sometimes hair blows in the wind but most of the time hair just lays there like that it's a strange color it's color is red it's all hair red no sometimes it's a black color or a yellow color or a gray color or many colors in between in any color it's a myth as i said hair is sometimes unruly and has to be brushed or combed hair would you please straighten yourself up now that is much better now let's everyone get together webster haven't you forgotten one very important member eyes ears nose hair mouth and teeth who did i forget use your senses webster they can do nothing without me i tell them what to do and when to do it i'm their leader why can't we see you because i'm inside your head i'm your brain how could i forget you brain oh i have a drawing here see the brain is there inside your head thank you webster members please organize yourselves into your proper places i hate to say this brain but we don't know where to go okay mouth and teeth you go there and you are to eat drink talk and brush eyes go there your job is to see ears go there your job is to listen nose go there your job is to smell hair there and just stay cold now all of you work together and help each other thank you brain each of you has a brain hair eyes ears nose mouth and teeth use them to help you work and play now let's play a game as i point out each member of our group you point to it with your hand and do what they do point to your hair now eyes blink ears listen nose smell now give us a smile and and show your teeth see isn't it fun to work together thank you let's go orson [Music] [Music] so oof that one's rough um i have other films in that series featuring those puppets orson and i can't remember the owl's name um but yeah so we got um kind of a low rent jimmy stewart uh dollar store edwin as somebody said and uh god um yeah not great not great puppets got a lot of those films with a lot not very good puppets um all right this film's about the post office [Music] next week is mother's birthday and susan and jimmy bray are getting a present for her do you really think she like it i think she will jim they've written a letter to a company in milwaukee that sells through a mail order catalog jimmy wants to be sure that he has addressed the envelope correctly he's never addressed an envelope before then you write the state w i s period there how's that that's fine let's see now name on the first line number and street on the second city zone number and state on the third the zone number tells what neighborhood in milwaukee the letter goes to and in the upper left corner is the return address there's no zone number here since evanston doesn't have zones yes jimmy has addressed the envelope correctly but it's not ready to be sealed yet they have to enclose the money the catalog says not to send cash but to send check or money order and susan knows she can get a money order at the post office here's the post office in evanston all the mail which goes in or out of evanston passes through the post office in the post office susan is waiting to buy a money order to put into their letter meanwhile she asks jimmy to buy a stamp the clerk writes out the money order it's called a postal money order because it represents a promise by the post office to pay a dollar seventy five meanwhile jimmy is buying a stamp for the letter the money the post office gets for stamps helps pay for the people who work in the post office and for other costs of sending the mail the post office sells stamps of many different kinds and prices the clerk tells susan to write in the name of the company when they receive it the company can take it to any post office to get their money susan gives the clerk a dollar seventy five cents plus ten cents to pay for the money order the post office is run by the post office department of the united states government in washington almost every town and city has a post office some like this one in evanston some bigger and some smaller depending on the size of the town the mail can go from any post office to any other in the country and to foreign lands as well susan puts the money order into the letter and it's ready to mail the address is right it has a return address and it has a stand jimmy wants to be the one to drop it into the slot he's careful to put it into the right slot to help the post office do its work let's go behind this wall and see some of the work the post office does the tray that the letter fell into is emptied onto a sorting table letters which go by regular mail usually go by train or truck people in a hurry can send letters by air mail airmail letters cost more for stamps he puts all the air mail letters together special delivery letters must be clearly marked and carry a special stamp the clerk puts all the special delivery letters together too they will be delivered as soon as they arrive now the letters are ready to be cancelled the post office has a machine that does this the machine makes the mark on the stamp so that it can't be used again but canceling does more than mark the stamp in the circle is the name of the post office the time the letter was cancelled and the date on which it was cancelled this is called a postmark some letters are cancelled by hand because they're too thick to go through the canceling machine or because they're the wrong size now the letters go to these cases where postal clerks sort them according to where they are to go and how they are to get there some letters go to places that are close by often these letters will be delivered by truck letters addressed to more distant places usually go by train there's a special case for letters addressed to foreign countries they cost more to mail than letters for this country this case is only for letters that will go on train number 161 to wisconsin this clerk knows the name of every town where the train stops in the right order jimmy's and susan's letter goes into a slot for letters addressed to milwaukee as each slot fills up a clerk takes out the letters to tie them into a bundle the post office has machines that quickly tie the bundles faster than a man can do it then the bundles of letters are tossed into large bags called pouches each pouch will go to a different place the bundle with jimmy's and susan's letter goes into the pouch for milwaukee packages in the mail are called parcel post they are sorted much like letters the workers take them from this moving table and toss them into the right hampers then the packages in each hamper are sorted into different mail sacks it's 4 20 now all the mail has been taken out of the racks train number 161 is due in evanston soon the pouches for train number 161 must be closed and locked every letter pouch is locked before it leaves the post office in order to keep the mail safe inside only postal clerks have the keys the same key works all the locks the pouches and sacks are taken from the post office by trucks to start on their trip the post office has a schedule when different pouches are locked according to the schedules of the trains trucks and airplanes they are to go on some air mail will go to a helicopter field at the edge of the city the helicopter will carry the mail quickly to an airport where mail can be put on large airplanes helicopters are used in some of the larger cities and their suburbs to speed up the mail service at the airport airmail first goes to a special airmail post office here the mail is arranged according to the schedules of the airplanes then the pouches and sacks of mail are loaded into airplanes which take them quickly to the cities they are bound for regular mail usually goes by train here is train number 161 pulling into the station this train has a special car called a railway post office which is really a post office on wheels a post office truck has brought the pouches and sacks to the station jimmy's and susan's letter is in one of these pouches as the train rolls along postal transportation clerks open pouches they have picked up from different city post offices along the railroad line in some pouches the letters are already bundled and they sort the bundles here's the bundle with jimmy's and susan's letter in it some of the mail the clerks must sort into slots just as the clerks in the city post office do every clerk carries a pistol to protect the mail along with the key that opens the pouches stacked near the door are the pouches that are to be put off at the next station and so the postal transportation clerks keep working as the train rolls along it's early in the morning several days later the mail carriers are coming to work at the evanston post office they must be ready to leave the post office by eight o'clock to deliver the mail they have a lot to do before then they must sort the mail that has come in since yesterday each carrier arranges his letters in the order he will deliver them parcel post must be arranged this way too it is sorted on the same moving table it will be delivered by truck and here is the package addressed to jimmy and susan bray the birthday present has come at last mrs bray has no idea what's in it she can hardly wait for jimmy and susan to come home from school oh a card two oh happy birthday mother you're the greatest oh thanks okay okay now let's turn it over like this here see i have the scissors i got a year here in here come on now [Applause] and that's how the post office helped jimmy and susan surprise their mother with a birthday present so wow yeah i i have footage of also a german post office that i was trying to find it's silent though um i think it's silent i don't know i'm going to try to find it i i got a bunch of uh german educational films kind of from the 30s um which are pretty great except you know some of them are third reich related um but the post office one is pretty pretty great nonetheless um this film is beautiful the subject matter i don't know but it's it's beautiful industrial footage uh and um the soundtrack's a little noisy at first but it gets better this is sulfur [Music] [Music] liquid sunshine for four thousand years the servant of man what is it whence does it come this is the story of sulfur sulfur yellow mineral without which there would be no automobiles no airplanes no newspapers no motion pictures no telephone none of the new wonder drugs self drugs no dramatically combating once fatal diseases the united states produces over 80 percent of the world's output of crude sulphur most of it comes from great salt domes along the gulf of mexico in louisiana and texas from new orleans to a point south of houston and down toward galveston is the great sulfur producing area seven distinct sulfur mines in this region produce a total of three and a half million gross tons annually this quantity would make a 70 million cubic foot block of sulfur almost twice as large as the empire state building rising over a thousand feet into the air and great salt domes such as this with the sulfur-bearing strata shown in cross-section are about 1 000 feet beneath the surface of the coastal plains the modern method of mining sulfur as a liquid was conceived and developed by dr herman fresh in the 1890s the mineral is melted underground by superheated water and pumped to the surface through pipes [Music] a well such as this is drilled by the most modern equipment [Music] to the sulfur-bearing bed and equipped with pipes of three sizes one within the other down through the large outer six inch pipe superheated water 300 to 330 degrees fahrenheit flows to melt the sulfur the melted sulfur rises to the surface through the three inch middle pipe driven upward by the compressed air which is forced into the well through the small one-inch pipe for the fresh method of sulfur mining then the prime requisites are compressed air fuel and millions of gallons of water here on the shore of a peaceful stream stands a pump house which collects the water necessary for mining sulfur the water goes to this great reservoir which covers nearly 300 acres and holds about a billion gallons of water through this outlet river pumps discharge 40 000 gallons each minute into the reservoir then through underground conduit the water flows to the power plant huge water softeners are just outside the power plant the water is conditioned in these to make it suitable for use in the steam boilers and heaters the power plant itself houses the most modern equipment furnishing electric energy for all operations through this mammoth switchboard energy is distributed to the plan and out to the field several miles away four tons of steam are generated every minute in the boiler room to heat the millions of gallons of water required in the mining operations to avoid any possibility of a break in the hot water supply the power plant is equipped to utilize oil fuel if the natural gas supply should be interrupted [Music] after being softened and conditioned the water flows into these heaters they can deliver 9 million gallons of water at 330 degrees fahrenheit every 24 hours the superheated water flows directly to the field through this great pipe system under pressure from these 65 centrifugal pumps which provide a continuous supply of hot water without hot water production would stop now let's see what happens to the water in the power plant the water tube boiler generates steam at 100 pounds pressure some of this steam operates turbines that generate the electric power required in the plant itself but most of the steam is used directly for heating the water the heater is a large jet condenser which employs the latent heat of the steam to heat the water over four pounds of water are heated for every pound of steam generated in these curries being compressed while the water is being softened and heated each day these machines compress over a million and a half cubic feet of air to a pressure of 500 pounds per square inch then superheated water compressed air and steam are forced through this intricate pipeline system to the sulfur well some miles away when the superheated water and the compressed air reach the mine the superheated water flows down into the well down some thousand feet until it reaches the sulfur bearing department [Music] then it passes through the perforated end of the pipe into the sulfur bed the melting point of sulfur is 240 degrees because its specific gravity is twice that of water the sulfur separates immediately from the water instead of dissolving and it starts to rise in the three-inch middle pipe then the compressed air in the one-inch pipe forces its sulfur to the surface downward flow the superheated water in compressed air and upward comes the melted sulfur thus by this ingenious method sulfur is made available to world industries but what becomes of the millions of gallons of water that have been pumped into the dome to melt the sulfur to fissure flow wells called bleed water wells are drilled and the water is drained back to the surface this fleet water is treated to remove major impurities then discharged into disposal ditches whereas salt water it flows to the gulf of mexico from the well the melted sulfur flows directly to a relay collecting station such as this and every day from five thousand to seven thousand tons of this yellow mineral flow into great sumps [Music] automatic meters accurately register the output of each well as the sulfur is discharged into the sump [Music] after being measured the sulfur still liquid is piped to great storage mounds called vats here first corrugated metal siding is put in place to hold the sulfur before it solidifies then the liquid sulfur is distributed evenly in 1 8 inch layers each layer being allowed to cool before the next is sprayed into place gradually a huge block of sulfur is formed each block covers an area as large as six city blocks and as high as a five-story building yes large enough for three football fields with space between them dynamite is necessary to break up the immense sulfur block once it has solidified rotary rigs drill holes for the charges the dynamite is lowered into the holes [Music] the charges are tempt and the primer is placed [Music] and there she goes [Music] after the blast a bulldozer levels the surface to facilitate loading the gondola cars the tracks are moved as close as possible to the vet then the track moving machine brings the tracks right up to the loading face of the vet huge clam buckets capable of lifting two tons at each grab load gondolas with the sulfur [Music] then on to the scale house where each gondola is weighed on under track scales should a car be light additional sulfur is added so that the contents of each car is exactly as ordered great train loads of sulfur leave the mine some go directly to inland destinations the remainder is set by ship to domestic and foreign markets the gondola cars are unloaded at port some are dumped into bins which hold 35 000 tons these are kept loaded for emergency part of the mineral goes into giant hoppers then to a continuous conveyor belt which carries 600 tons per hour the sofa is weighed twice on the belt in the way house seen in the background after being weighed the sulfur is poured through grayed out direct loads of waiting ships which will transport it throughout the world [Music] from the united states to the world at large sulfur 3 500 000 gross tons produced each year [Music] over 20 approximately 750 000 gross tons is exported to foreign countries [Music] the remainder 2 750 thousand gross tons is used in the united states most of this is burned to make sulfuric acid but the remainder supplies non-acid uses to make wood pulp and paper 325 000 tons [Music] to make chemicals plastics sulfate drugs dyes carbon disulfide carbon tetrachloride refrigerants and other chemical products 200 000 tons to vulcanize automobile tires garden hose 1001 rubber articles of everyday use 50 000 tons [Music] to keep insects from eating crops and fruits and red cattle and sheep of lice 75 000 tons [Music] the non-acid uses of sulfur are then wood pulp and paper 325 000 tons chemicals 200 000 tons rubber products 50 000 tons sprays and insecticides 75 000 tons miscellaneous including cement gun powder synthetic rosins and bleach 100 000 tons total 750 000 tons what about the remaining 2 million tons that are burned they make sulfur dioxide [Music] so2 sulfur trioxide so3 sulfuric acid h2so4 sulfuric acid the workhorse of industry [Music] 30 of all sulfuric acid goes into the manufacture of fertilizers to improve the quality of corn wheat oats and other american crops 15 for the manufacture of such chemicals as alum salt cake hydrochloric acid [Music] and 13 for lubricating oils and gasoline [Music] 12 to remove scale from steel and prepare it for galvanizing tinning and electroplating eight percent to make ammonium sulfate and coal tar derivatives from coke oven gases another eight percent for rayon and other synthetic textiles [Music] seven percent in the preparation of paints and pigments [Music] the remaining seven percent in glycerin pharmaceuticals safety glass storage batteries woolen clothing photographic films synthetic rubber shoes water purification alcohol sugar soap and glue [Music] the acid uses of sulfur then fertilizers 30 [Music] chemicals 15 oil refining 13 metallurgical 12 coal products 8 crayon and other textiles 8 paints and pigments 7 and miscellaneous 7 [Music] total 100 or 2 million gross tons of the three and a half million tons of sulfur which the united states produces each year [Music] yes this saffron mineral vital to life and living this is the story of sulfur [Music] god you couldn't hear anything that i said i'm sorry i just saw that i didn't have the microphone on anyways i had to open up a can it stank of vinegar that's what happens when it's airtight uh this is the last in the series of uh what will blank kid do this is what will ted do i'm sorry i thought i clicked it on and i didn't all right here we go [Music] what do you think of it huh it's neat and i thought this one was best well i looked all over downtown for it today i'll tell you is it a fishing boat it's a sailing boat made in france see everything on it works everything does it really sail sure it does look give this a try right here it works you bet it works ted now look try this right here try anything you want to because everything works on that why don't you take this maybe a couple of your others to school yeah it's time they all saw it yeah and i was just talking about it yesterday jim the class really has enjoyed the story that you wrote and i want to compliment you on it's one of the best ones that's been written this year and you certainly deserve the fee you got on it it was well planned and you came to a good point at the end [Music] [Music] oh [Music] how much do they cause like [Music] well i'll tell you you talked to your teacher it's about time those kids saw your collection it took me a long time i'll tell you that this is a good lesson for all of us how many times has ted told us about these things that he's done at home and we really haven't even believed him just lovely yes how did you make it well this is it's getting late now it's time for us to go back to our seats let's take our seats quietly and then we'll ask ted to stand up and tell us more about how he made this boat [Music] i know you're all anxious to hear what ted has to tell us this morning this is really going to be an interesting uh sharing time isn't it ted just relax ted don't be nervous put your shoulders back stand up nice and straight and speak out in your nice loudest clearest voice now we want to know all about this book that you've brought to school all about how you made it where you got the materials so you had to say you made the boat are you going to get out of this one well first you go out and buy the boat pieces and the designs and the paint and the wood and then you well first you've got to do is get the rudders and stick the rudder on your sails i'm sorry mrs mandock i lied i didn't really make the boat's eye bottle what are you going to do better decide quickly everybody is waiting i thought he was gonna have a panic attack in front of all his fellow students oh my gosh what a great uh i'm sorry that i don't have more in that series i love little ethical dilemmas that kids face many of them do resonate with me being a kid and making poor decisions and then having to figure out what to do next it's a bit of therapy it feels like uh anyways thanks everybody for tuning in today i should say i did a little bit of math uh and by math i mean i actually look back in my calendar and we've been doing this for more than a year uh the 15th 2020 is when we did our first uh lunchtime streaming show and i did it at the archive and then that weekend i realized that i couldn't socially distance from my assistant and so uh we had to um i had to set up in the basement of my house so that my assistant could still work i didn't want to put constraints on him and so i was like well i'll just distance myself and he can continue to work um and so uh it's been a hell of a year and i appreciate you guys being there um and i also appreciate nate for buying me some coffee uh thank you so much he used this link right here uh www av geeks also hitting like and subscribe is another way to say thank you and to say yes we're interested in what you're wanting to do and go into avgeeks.com there's more stuff up there that we've been digitizing over the last 10 years um i'm gonna get a shot next week i think because they finally opened it up to my group and um so i'm gonna get vaccinated and eventually make my way back to the archive but i still want to continue doing this daily i don't know but you know we'll give it a shot we'll see how life um what demands life has on me uh post vaccine but um i do very much appreciate your eyeballs and your attention your comments and you're bearing with me when i don't unmute the microphone and all the technical problems that we've had because we have had a slew of technical problems all the copyright violations that you've watched and enjoyed along with me um all those things so thank you so much very much love your attention and your and your kind thoughts um you know please rewind and love each other including yourself very important and uh i'll be back tomorrow how about that um unless weather
