[time-nuts] Vintage Quartz Crystal Manufacturing

Can you say "Mr Rogers' Neighborhood?" I knew you could... He (along with creepy Mr McFeelie) always ran segments on how some item was made. Geared towards pre-schoolers, but always worth watching. - Compare the Science channel's new "How Do They Do It" to the older

Re: [time-nuts] Vintage Quartz Crystal Manufacturing

I watched the video when it first hit the list and found it interesting, as I would any complex industrial process. I've seen another crystal film that was available a few years ago as a file, but can't find the reference. The people who can't believe people ever worked under those conditions

[time-nuts] HP 5065A questions

Hello time-nuts, I have recently had the opportunity to play with an HP 5065A rubidium standard and have some questions. This unit has been powered down for quite a long time, it appears to be almost working. I can see both the 137Hz and second harmonic signals but they seem very low. In the

Re: [time-nuts] Vintage Quartz Crystal Manufacturing

Hi, Sometimes this game goes very silly. Earlier this year I was invited to come and talk in the US since it seems extremely hard to learn about real-life chores in GPS usage, since every american company would not be able to tell anything useful as it is "business confidential". I was even

Re: [time-nuts] Vintage Quartz Crystal Manufacturing

Hi As I said, there was more than one side to the controversy. The crystal industry being what it was, what one company knew, the others soon knew. Indeed, there was money made on the film …. Bob > On Sep 25, 2016, at 12:38 PM, William H. Fite wrote: > > So cynical, Bob.

Re: [time-nuts] Vintage Quartz Crystal Manufacturing

So cynical, Bob. ☺ The fact is that many, many short films of this type were made during WWII and to a lesser extent during the Cold War, primarily for educational awareness of the general pubic as well as members of the armed forces. A great uncle of mine who was an executive at RCA oversaw the

Re: [time-nuts] Vintage Quartz Crystal Manufacturing

Hi The film on YouTube was done by a crystal manufacturing company. The production of the film was paid for by the US Government. The company made a chunk of money off of making the film and then preceded to use it as advertising for the next 20 years. If you dropped in to a crystal

Something tells me those crystals cost more than 10 cents... and were probably quite a bit worse than today's 10 cent Chinese processor crystals. Young'uns today have no idea how good they have it... and get off my lawn! I just sorted through a $10 (shipped from China) bag of 100 crystals
