Electrology History

Even not the least powerful it seems…

It would be really nice to see the circuitry of such a beast - a funny project for creative DIYers.

@Michael: thanks for showing this one!

PS: googling for Kree Radiomatic led me not only the the pictures shown in this thread but to to following article which includes the circuitry of the very first blend machine: http://www.cosmeticsandskin.com/ded/thermolysis.php

(the biggest obstacle for building this is obtaining the output transformer of the RF oscillator…)

Hinkel Chemi-Therm 1930s

This unit was made before 1938; before Henry and Art thought about combining DC and HF. Notice the switch in the middle? This would put you in DC or HF mode; but not blend (yet).

Fascinating that even during the Great Depression, women had money for hair removal! Yes, it’s THAT important. Food or hair removal? Many decided on hair removal!

Great information Beate! I have a ton of Hinkel’s electronic schematics for his units. If you like I will send these to you.

I know lots of you don’t use foot switches … I do. Amazingly, the “ancient” Kree foot switch is perfect! (I remember my old one and, it was great.) This really old one (on the “radio-Matic” is in perfect condition and I’m going to adapt it so I can use it.

Thanks a lot. That would be really nice. PDF would be just fine…

I don’t know much about this unit. Like the previous machines, this was a “we can do it all” unit: thermolysis, auto-thermolysis, DC single and multiple … the whole deal. Such units were common 1930s - 1950s. This “Juniper and Norris” machine was made in North Hollywood California.

Of interest are the two metal plates on the front ledge (also notice the mounting bracket for the multiple needle arm). I looked inside, and these plates were attached (to the DC circuit). My guess is that the customer was supposed to put her fingers on the plates to close the DC circuit?

(Beate: most of these schematic are on very large paper and hand drawn in a notebook … I don’t expect they’re on a PDF … I could scan them perhaps?)

Oh “Meine Gute!” I have 10 more machines to go!

Getting sick of this yet?

(These old machines smell horrible! But not as bad as an “old electrologist!”)

Please, please, Michael, before you let go of these beauties, make sure they do not end up in a private collection, but they will be exhibited in a place where everyone can see and study them if they wish.

If the company Hinkel has left this treasure in your hands, it is because there are very good reasons. They are well aware of your generosity to share information, your lack of interest in money, and that you are only committed to one thing: the absolute truth.

I can not imagine a BETTER hands as a guardian of our HISTORY.

Holy Catagen Jossie!

After all, Catagen is another way forward.

Something like … a subphase of PERSONAL Anagen.

Here’s another similar “all of it” unit (no multiple-arm). Made in Los Angeles by Armenta this was called the “Mo-Gil-Ner Automatic electronic epilator.” This had a metal cabinet and, like all these machines, REALLY heavy! (Armenta also made their own epilator with their name on it.) Additionally, the name was “Mo-Gil-Ner,” because nobody could pronounce “Mogilner!” (I believe a Scottish name?)

The unit did HF and DC but not together. Of interest is seen in the right-hand corner. You had the option of using “rectified” or “battery” DC. Part of the “modality wars” of the past was about the DC current: battery or rectified (DC “made” by rectifier from the regular “wall current” … AC). (I actually know the historic arguments.) I suppose Armenta simply gave the operator the option. We don’t hear THAT argument any more … thank goodness.

Like ghosts in a cemetery, these antiques tell us their story if we listen to them. Indeed, they ARE beginning to “talk” to me and they are telling me a very fascinating story. Do you see the patterns too? Of course, all of these details are preliminary … I have lots of digging to do … help is very much appreciated!

Also interesting is the terrific “hand-held ‘ground’,” (really DC return). The thing is made of pure dense graphite and would be an amazing conductor. It’s in perfect “brand-new” condition.

So far the 70-year-old foot switches, DC “ground” and needle-holder clips are WAY better than anything we have today! So far, all these units seem to be working too.

They are still not ready for the “land-fill” after all these decades? Is there a lesson here?

Have the electrolytic capacitors changed and they will keep going as long as you can get tubes for them Michael. BTW the one I see as a driver in the one machine looks like a 6L6 which Beate will tell you is a common tube used in guitar amplifiers like the Marshall.

Absolutely is a “6L6” because I used to have to replace it!

Mhmm, Marshalls are Britisch. They eat EL34s. Fender amps use 6L6 - and chances are good that these tubes will be produced longer that we live.
In these old devices ALL capacitors need to be changed, not only the electrolytic ones, but these foremost. Truly museal restore jobs include opening the cans of the electrolytics, mounting new caps into the cans and closing them again.

And yes, the valve might indeed be a 6L6

Such a machine must be used to remain usable! At least once per month.

Quickly … here’s the 70-year-old “ground” and cata-roller … MUCH nicer than the ones used today, for several reasons. They also have a nice “heft” feeling to them …

… and have been made smaller in order to give us more protection if clients start to reach their limits and react strangely? :smiley:

Ja … ein grosser Schlag auf den Kopf!

(I am just a 6" tall Lilliputian as I struggle to understand this conversation on the mechanics of these boxes of energy).

If you respect the heaviness of a metal box from years pass, you will still find that in the Instantron Elite and Dectro’s Xcell Pro and Platinum. Very heavy. Metal. Sturdy. Boxes.

I don’t understand it either Dee. Okay … a tiny bit here and there (from Hinkel and Bill Schuler). And, it doesn’t matter either. People can still drive a car, and be REALLY good at it … without knowing how a motor works.

I used to work on motors all the time as a kid. We all did and it was great fun (used to drag race too). Today, it’s nearly impossible to work on modern car motors: you can’t “get around” the computers.

When I open the hood, I always wonder where “they put the motor?” And, I’m keeping my old Mustang because I can still tune the engine and repair almost everything myself! And, it looks like a real MOTOR too.
