Title: Coin operated desk telephone for local calls - has coin testing device and forced cashing-in of coins
Inventor: MAND HARALD
IPC: H04M17/02
Filed: 1974-05-14
Abstract: The dialling tone is switched through to the caller only when, after insertion of a good coin, the pay button is pressed. This movement is transmitted through a rack and pinion system to the slide release pin, which closes a contact of a first microswitch and locks the gate to the coin channel, so that the coin is pushed by the pressure plate. When the pay button is released, the coin passes a lever testing it for a minimum dia., which in turn moves the deflector that takes a storing position. At the same time a contact of a second microswitch is closed and the dialling tone is switched through. The coin passage to the cashing-in channel is unblocked by an electromagnet operated by cashing pulses.

Title: Railway wheel-bearing condition monitor - with temperature sensor linked to towing vehicle to signal excessive temperature
Inventor: SAUER KARL DIPL PHYS
IPC: B61K9/06
Filed: 1974-06-01

Title: Electronic programme controller - based upon signal level switching devices, with signal generator scanning potentiometer outputs coupled to comparators with preset ref. leve
Inventor: RADOVIC ZORAN
IPC: G05B19/07
Filed: 1975-06-12
Abstract: A simple programmable sequence controller using electronics and suited to manufacturing process applications utilises threshold switching techniques. A signal generator (1) sequentially scans the outputs of a number of preset potentiometers (3) each of which is assigned to a machine operation. In this way each operation is represented by a specific signal level (Ust) appearing sequentially on the output line (4). Output levels are detected by a number of comparator stages (5), each with a variable level reference input. The generated output orders (A1-An) are transmitted to XOR gates to generate the inputs to machine units. The reference inout levels to the comparators and the potentiometer settings are readily modified to change the sequence.

Title: Rotor assembly for small synchronous hysteresis motor - uses laser beam welding process for joining hub and rotor disc to form one unit
Inventor: HARTMANN GUNTER DIPL ING
IPC: H02K15/02
Filed: 1975-09-30
Abstract: In small synchronous hysteresis motors it is important no irregularities or deformities arise in the rotor which may interfere with satisfactory operation. The rotor comprises a shaft (2) onto which a hub (1) is pressed. The rotor disc (4) is mounted on the hub and attached to it by spot welds (5) produced by a laser beam welding apparatus. The use of a laser gives very high energy input for a very short time and this virtually eliminates rotor disc thermal distortion and also alteration of its magnetic properties. Typically the assembly takes place on a jig (3) which positions the disc correctly in relation to the hub (1). Welding takes place in the annular gap(s) between hub and disc.
