Receiving this kind of collection sort of marks a transition towards being a more serious museum, with an emphasis on institutional memory, rather than just a collection of random stuff (not that there was anything wrong with that). It will be very interesting to see how the museum evolves. It wouldn't surprise me if there are many companies that find themselves in a similar position in the coming decades.

16:13 This translation might sound a bit weird in some places because the source does as well... ;) I tried to correct logical errors as good as I can. Electro Polygraph 662 The drive unit contains the synchronous motor with starting capacitor and a change-over gear for 5 different paper speeds. The connection terminal for the mains cable with ground wire is located on one of the PCBs on the side. On the other is a switch for switching the motor on and off, an electrical switch for forward and reverse gear and a button for operating the step gear. If the knob is turned slightly clockwise, it can be pushed in or out. The numbers engraved on the push bar indicate the selected gear. Level 1 2 3 4. 5 Paper speed 0.05 0.5 5 50 100 mm/sec The two rollers for the paper are located outside the gear box and can be removed from their bearings. The smooth flange can be removed in order to place the supply roll on the roller or to remove the rewound paper from the rewinding roller. The rollers must be inserted in such a way that the toothed flange engages with the protruding gear wheel of the gearbox. The drive unit is symmetrical. The paper runs from the supply roll over the inclined plane, is driven by the driving shaft arranged in the apex and runs again over an inclined plane to the take-up roll. The two inclined guide plates can be opened so that the various bearings can be conveniently oiled. The motor and the electrical circuit are located under the insulation cover (be careful with removed cover - 220 volts!). The drive roller is in two parts so that the drive pins can be adapted to the holes in the paper. The recording paper is inserted with the cover removed. However, the motor should only be switched on after the cover has been screwed on, as the two springs that are attached to the edge of the cover [Illustration] Electro Polygraph Type No. 662 of the drive shaft are attached to the cover. The cover is a box-shaped housing containing the recording magnets. It is fitted in such a way that its two lateral slots fit under the knurled screw knobs with which it is fixed to the drive unit. On the rear side are the connection terminals for wires or banana plugs, a common positive pole (red) and a separate negative pole for each magnet for an operating voltage of 12 or 24 volts DC. The writing levers with the writing tips protrude from the front. Each recorder can be lifted off the paper individually and there is also a swivelling bracket with which all recorders can be lifted off at the same time. This makes it possible to first use only one half of the recording magnets, then, with the recorders raised, switch off the paper feed and let the strip run backwards, after which the remaining recording magnets are used to record in the second pass. The high speed of 100 mm/sec can be switched on for the reverse run. However, it is not recommended to pass the paper through more than twice in forward motion, as otherwise the perforations may be damaged. There is no special time recorder, as the drive by means of a synchronous motor and stepped gearing makes time marking unnecessary. However, it is possible to feed one of the recording magnets with the periodic interrupter No. 654, page 10, and thus record time stamps. Maximum frequency 100 pulses/sec Dimensions: 26 cm long, 19 cm wide (with slide gate inserted) 20 cm high. The electro-polygraph comes in a pouch. The electro-polygraph is supplied in 2 types, which differ in the number of recording magnets. The motor voltage T10 or 220 volts, 50 periods is to be specified in each case. Magnet voltage 12 or 24 volts direct current. No. 662 Electro-polygraph with 12 magnets; Weight with pouch: approx. 11 kg. No. 663 Electro-polygraph with 6 magnets; Weight with pouch: approx. 10 kg. No. 664 Paraffinised paper, 12 cm wide, in rolls of approx. 50 m length.

The mechanical Tachs starting at around 9:50 are very, very useful. Jaquet made more then one type, including flyweight and timer types. They are general purpouse for use measuring ahsft speeds on motors, transmissions, machinery, etc. Usually with a set of contact tipe for getting into a 60degree machined center on a dhaft, and often with rollers for measuring surface speed (conveyor belt and the like) I still use them. The flyweight type direct read and can show speed variation, the timer type time for six seconds (usually) with a mechanical clock that engages and disengages a clutch for th eindicator, giving an average over the timing period. The timer type are VERY accurate if maintained like a fine mechanical watch. I first used them with large, low speed engines, where the speed varies during each rotation. They were a distinct upgrade from the pure rotation counter used with a pocket watch from the 19thcty into WW-II. Jaquet sold them under their name, as well as supplied them to others with different labeling, such as Herman Sticht in the US

Also those types of tachometers wind up the clock mechanism by using it. Which is super smart, and means that pressing it without using it can wind it down.

[@YCbCr]

Timer type tachos are still used on locomotives! I like them for their distinctive rhythmicity. They provide tachograms to waxed paper as well as speed-dependent circuit switching.

[@henklass]

29:20: Eichraum = calibrating room

[@KeritechElectronics]

Sooooooooo many things of beauty. An absolutely impressive haul. So Fran-tastic it outfrans Fran herself... and Dave Jones as well. All hail the Owlotron!

As an engineer this was awesome. The mechanical tachometers are works of art and last forever. The stroboscope with the sight is really useful, so that ambient lighting doesn't affect it.

[@cambridgemart2075]

11:00 is an optical tachometer, you put a reflective strip on the part rotating and line the optical head up with it.

[@thomasamsterdam]

13:02 Schwingungsmesser unbekannt = Oscillation meter unknown

[@peterschwegler2377]

For measuring oscillations on overland high voltage line cables.

[@nonnufan]

Loving this shit, gents

[@DanielvanKATWIJK]

The stroboscopic tachometer is a non contact one. You look through the device aiming a rotating object. You adjust the stroboscopic frequency till the object appears static and then you have a readout of the rotating frequency. You don't need a spot or sticker like for modern ones that give digital readings. You have to be careful, the readout can be double or half the actual speed.

[@DetroitMicroSound]

Excited to visit your museum one day!!! They couldn't have chosen a better group of folks to care for their history.

[@ibanezleftyclub]

You could hook up the mechanical tachs to a display where you can have users spin a wheel and see how fast they can get it up too. Even more fun if you add in some gearing they can change out.

[@DanielvanKATWIJK]

This is a real dream collection for tech engineers. Lots of old memories from when I had my first job (did lots of instrument calibration, technical documentation translations...).

[@DanielvanKATWIJK]

Eichraum (picture shown at timestamp 29:07)in English is calibration room. This is where they calibrated all instruments. One of my former jobs in the '80's and '90's when I was working in the Netherlands (not for Jaquet). If you need German translations I may help.

[@traumgeist]

I build tachometers (for cars). Those tachos are probably for measuring the speed of motors for vacuum pumps and other lab and medical equipment.

[@AMPProf]

[@ElectronicTonic156]

At exactly 15:40, you moved something within the box. From what I can see through the bubble wrap, it looks like an electromechanically actuated stopwatch which I have. Jaquet model 309D. I made a video about it 10 years ago ( kzbin.info/www/bejne/eWHUaX6XmtGXgck ), and used it to test the timing of my thermal time delay relays.

[@jaredwblack]

Amazing! 🙂

[@Wagoo]

[@sivoltage]

[@edgeeffect]

I was just thinking about all these tacos in a museum display... I've got this collection of mostly DC motors... having them hooked up to some kind of microcontroller outputting perhaps varying PWM through power transistors would make a nice dial-flickering display.

[@cambridgemart2075]

You had me confused because I didn't see any Mexican food! Then I figured out you were talking about tachometers.

[@samphillips4925]

So cool! You can see all sorts of crazy stuff with the strobe o scope.

[@Colin_Ames]

What a fabulous haul! Plenty of material for future episodes.

[@markedis5902]

Jaquet made speed and rotational sensors used in railway metro and tram. Also diesel and petrol engines, turbochargers, pumps and compressors. I think it is a very different jaquet that did anything medical

[@orchestratedpassage9468]

So when you opening the second building🤣

[@pop_ulation]

i tried to come up with a clever comment but the best thing i could come up with is "i love you" so there you go

[@Simple_But_Expensive]

The analog writers are strip chart recorders. I can’t see it well on my IPhone, but it looks like they record 3 variables. They usually use 4-20 mA, 0-5 V, 1-5 V, or 0-10 V inputs.

[@rupertkingsley]

I saw at least one doodad, three thingamys and a couple of whatchamacallits. Hope this helps

[@ClayMann]

you missed the duufers and later on in the line the thingamys had thingamabobs but I didn't see those.

[@lucalorenzo]

this is my absolut feel good content :) love it. Excited for the future videos what you gonna do with all of that

[@KmF0X]

That Syncardon must be something about blood and a limb The top left dial says something about cardiac signal And there's that text in the middle where it's written "Gonflage de la Manchette" That sounds like it's about inflating one of those things we use on the arms to take blood pressure

[@gm7836]

That's correct - I think they were used for improving circulation in limbs by rhythmic pumping (ooer) of a pressure cuff.

[@codebeat4192]

24:50 Adjustable High voltage (Kilovolts) generator. There is a guy on YT that use such thing to do experimental things (mostly very dangerous things).

[@edgeeffect]

The unboxing video to end all unboxing videos! All those displays and chart recorders and stuff will me with the urge to connect them all up to some kind of PC/microcontroller combination or Raspie Pi or something and have them all running like the scenery for THE most demented of 1970s Sci-Fi TV series you can imagine.

[@erickvond6825]

[@wmrg1057]

Now the fun begins documenting everything. Should have "asset" tags on each piece so you can track them. Almost need rf tags on your item so you can find them

[@sammacomber8769]

100% and a well crafted database with relevant info plus related files like scanned PDFs of any manuals, audio files etc. (my job is IT asset manager so… yeah… ha)

[@douro20]

Nowadays Jaquet is part of TE and they make precision sensors.

[@markedis5902]

Some of the tachometers are dial turn indicators judging by what was written on the box

[@DISCOTECHS]

Yeah, Dont chuck the boxes out. I would always collapse decent boxes if heavy duty double-walled. For reassembly, use Scapa Brand tape. Nothing else comes up to it. Lucien gave me a lot of it years ago when he was at Ellstree Studios as it was used as the Original "Gaffer" Tape, where gaffer tape got its name from.

[@simonhopkins3867]

It's clear what you have is parts of the prototype for the HyperEncabulator!

It was better that you waited till the end to open the docs box. I do so love opening a pallet of boxes and not knowing what to expect.

[@lukasmuller4360]

The thingmajiggy around 24:40 could be something to measure the eardrums response to pressure changes as an indicator for obstructions in the middle ear. My daughters doctor just recently used such a device to check if her hearing impairment is of mechanical nature. The device looked like it was from the eighties and it was way more handheld-er than this beast. 😂

[@agurdel]

No idea what it is, but I can read german, so here is my guesswork from the labeling. First of: It has a setup and a treatment mode. "Manschettenfüllung": It uses some kind of pressure cuff/sleeve. Also has knobs for "pressure", "pressure begin", "pressure length" and "pulse wave". The dial indicator in the middle is in mmHg in the blood pressure range. So its a treatment device that uses some kind of pulsed pressure to affect the blood circulation. I'm thinking for example a full leg cuff that inflates and deflates to pressures you setup in the device to support/improve blood circulation. /edit shouldnt have stopped before the "head devices"...

[@peterschwegler2377]

@@agurdel You are very close. It is a Syncardon which is used for treatment of peripheral vascular disorders. "zur Behandlung von Durchblutungsstörungen"
