Fingers elektrische Welt

Hello. Do you know some titles of old books ('30'-'40's, mabye '50's) abotu elevators? I do need some informations and the only detailed books in Romanian are post 1960. I'm intrested in books in German because most elevators instaled in pre 1948 Romania where imported from the German speaking count...

Hello. I couldn't find any drawing that shows how physically the star-delta connection is made. I mean a drawing with a motor and it's windings, not tehcnicall stuff showing winding and connections. I mean drawings something like the ones bellow. "Google" Translate: Hallo. Ich konnte keine...

What is the name of that magazine? In Romania we had "Buletinul/Revista GazElectra" ("The GazElectra Bouletin/Magazine") of Societatea Generală de Gaz şi Electrictate Bucureşti (General Company of Gas and Electricity Bucharest), from wich I was able to find some information. This...

But I wonder, there where magazines that published by the electricall companies (or German had a single one even befrore W.W. 1 or 1949) that could mention this. I don't speak German, so I don't know for what to look.

Well, I barley undesterand the German language, somtimes I deduce what they say, but some old books are very interesting. And the printing qualty is very good (printing is one of my other passions). It's intresting to see how Romanians (and probably not only them) copyed German desing of some electr...

I thought that some young rascals that seen "Blackboard Jungle" and ripped of seats after dancing on "Rock around the clock" by Bill Halley and his Comets (I know the song since I was about 13-14, I later seen the movie too) thought it was a good ideea for fun to throw rocks at t...

Oh, a joke connected to the fact that a lot of second-hand stuff is bought in Romania from Germany. Well, if it wasn't for the 2nd hand stuff, I wouldn't have had 2 LaserDisc (one P.A.L., one N.T.S.C.) now. And some C.D.'s with Euro-Dance (I turned 18 at the end of 2000, so I got a lot of Euro-Dance...

I've looked. Intresting.
But I want to be sure that doppletarif camed only in 1935 and no system was before it.

They used this methode? http://rundsteuerung.de/entwicklung/transkommando.html
or other one?

I transalted it. Intresting system. The mechanism makes me think at teletypers (fernschreibens). I only read about teletypers, since I'm not so old to have interect with one (trough all some where probably in use up untill I was around 22-23). Rundsteuertechnik means radio technology? They quited th...

I thougth that one of the methodes could be transmiting a signal via the power line, but didn't had any methode to see if that was correct. They used that signal back in the '20-'30's too? Intresting too see that the tarrif for hot water boilers was different then for the rest of the household appli...

Danke schon!
I didn't know what term too look for, but there is a good start!

Hello. I'm looking for user manuals for cash register used in Germany (or both West and East). Like "Secura"/'Ratus' A-20, but also other electromechanical ones. 'Ratus' A-20 was common in Romania and I'm curios what the keys did. "Google" Transalte: Hallo. Ich suche Bedienungsan...

Yes, those are the lamps.
In the 1st link, there is one German too.

Hello. In Germany you had some street lamps called pilzleuchte (I think that's mushroom lamp). Like this: https://www.sternenpark-schwaebische-alb.de/images/lichtverschmutzung/schlechte-lampen/pilzlampe-06.jpg I've seen these streetlamps in other countries too, like Switzerland, United Kingdom, but ...

Hello. Sorry again for speaking English.
I'm curios, in the old days of the pay (public phones) how the telephone exchange knew when to take the coin. How it the exchange communicated that to the telephone?

Hello. Sorry for writing in English, but I don't speak German (I know only a few words). There is one curiosity that puzzles me: how the old doppeltarifzähler that worked for 2 hours tarif, day and night (Nachtstrom) worked. I never seen even one in a picture (I searched with "Google") so ...
