In my computer graphics grad course at McGill in 1970 (yes, Seventy), my project involved Golden Sections nested and rotating. With double-precision Fortran code and a good Calcomp plotter, they matched exactly. Analog precision.
I would have absolutely no practical use for one of these... but I'd still love to have one... there's nothing quite like a nice high-quality, old drawing instrument!
Great - because of this video I had to go to eBay and purchase this device... never heard of it until now, and of course I had to have it. You are an influencer....
This would be a very handy device for rednecks like me. Since I suck at calculus, I sometimes have to use graphical solutions to solve problems. They get you in the ballpark or tell you what you're trying to do is impossible or impractical. That would make for an interesting series of videos - how to solve various electronics problems graphically. I know you've done a lot of smith chart videos; but it would be interesting to see graphical shortcuts to other kinds of problems.
@@IMSAIGuy Thanks so much! The online HP sliderules are cool! I tried saving the javascript page for offline use but it doesn't work right. I keep fiddling with it and figure it out.
@@IMSAIGuy Modifying the javascript to work offline on the HP sliderules looks like a pain. So I just right-clicked and saved the images. I'll drop by office despot, and have them printed on card stock, and join them together with some eyelets. A country boy can survive! Hah!
Used a similar aviation proportional divider extensively as a USAF Navigator. Could be used for quick time - speed calculation directly on a chart, or to more accurately measure latitude- longitude coordinates of a point for manual input into a flight computer. They were part of our issued equipment. Still have them (somewhere)...
Very nice! I've never seen one, but the construction makes perfect sense. GS - 3:2 golden ratio... and now you have a Debian logo, haha! Linien = lines, Kreise = circles. I think it has something to do with factoring pi in, but I'm not sure.
Exactly! I'm from the former East Germany. I still have a compass box from this company, which I got from my grandmother as a birthday present during my primary school days. Liked them very much as they are high quality. AFAIK, this company doesn't exist anymore.
The name of the company was E.O.Richter. The founder was Ernst Oscar Richter. The company logo on your guy toy is a combination of the letters E, O and R. The company was located in the town of Chemnitz in Saxony and started producing drawing instruments already in the late 19th century. They were known for high quality instruments. The logo was still used after the second world war but as a 'people's enterprise' they called the products Original Richter. After the end of the GDR the company finally went out of business in 1992.
KREISE means Circles, so that side of the tool divides the circumference of a CIRCLE in n equal parts. It's definitely NOT the name of the manufacturer. LINIEN, not Linlen, means lines, that side is supposed to change the proportions of lenghts. So it's definitely NOT the product name. These inscriptions only indicate the different purpose of each side. Apparently the creator of the video hasn't got the slightest idea about the German language. Worse still, he appears to have no linguistic or logical intuition. To the viewers of this video, the tool is wonderful and the video is worth seeing. But don't google 'Proportional Divider - Linlen by Kreise Co. You won't find it 😉
Ah! proportional portions! principals in divided proportional realities! theories in divisional proportions! do U feel divided from the rest of the world? well try a new reality in divided hemispherical proportions!! when U get out of bed. do U think left, right? hell bruh! just jump in a tater sack! the teachers didn't teach me how to draw! can google help? sure! Horasio! Ja! German! kind of cute!
GS in german stands for Goldener Schnitt which means golden ratio or literally golden cut.
thanks

Linien is German for lines and Kreise means circles.
I looked ten minutes after you posted this video and could not locate one with the precision pin. Bummer. Tools are cool. This one is right up there!
I wasn't exaggerating when I said it was rare
If this tool was made in Germany, then GS probably stands for "Goldener Schnitt"
Figured it out right as you finished 2nd square......!
Nice score! These Richter dividers are uncommon and getting one that hasn't lost the pin is even more rare.
I just learned about these and I think they’re cool. Side note I notice you have a machinist scale/rule, you have good taste in tools

Good piece of kit

RUclips tried one of those proportional divisions on my notifications for this channel.
It’s alright though. I just inverted the problem.

Golden ratio is 1.618...
@@tfrerich1/1.618 is 0.618. 1/0.618 is 1.618
GS is Golden section; 1 to 1.618
If it was GS it could stand for Gyllene snittet if its a swedish one. But I saw now its probably German
Yeah, I grok. Nice tool.
Try Original Richter. Made in East Germany.

If you have a milling machine that looks like a nice little project to build.
👌👍
Its made in Germany
Golden Section 1:1.618
Is that the 6 inch? I'm about to buy the 9 for chart plot. If this is the 6...I'll go with this.
point to point 7.5"

Don't need one to one. Any compass will do that.
but not at the same time 😎
