Patent DE-3237716-A1 (DE)
Inventor: MATTHES HANS G DIPL ING
IPC: H02M5/45
Filed: 1982-10-12
Abstract: An inverter circuit with a thyristor bridge circuit, a load circuit developed as a parallel oscillating circuit connected to the bridge circuit, an impulse generating circuit for supplying ignition pulses to the bridge circuit and an arcing time regulating circuit for controlling the impulse generating circuit in accordance with the arcing time. A down-and-up integrating circuit is triggered by an ignition impulse to integrate down until a discriminator circuit produces a signal indicating zero crossover of the load current, thereafter to integrate up until a second discriminator produces a second signal indicating zero crossover of the load voltage, at which time the integrator output indicates arcing time, and is applied to the time regulating circuit to control the impulse generating circuit.

Title: Three-phase asynchronous machine
Inventor: KOLMEDER WALTER DIPL ING
IPC: H02K9/00
Filed: 1983-06-01
Abstract: A three-phase asynchronous machine with a squirrel-cage rotor having a dedicated cooling device is proposed, whose special feature is that the short-circuiting rings are designed as short-circuiting discs and have cooling fins which are bent out of the plane of said discs and are integral therewith, and are formed from the part of the metal sheet from which the short-circuiting discs are cut, which is located inside the electrically effective internal diameter of the relevant short-circuiting disc. In this way, intensive cooling of the rotor cage is achieved without increased use of electrically conductive material, and independently of the shape of the rotor rods. Fig. 1 shows the sheet-metal blank of such a short-circuiting disc 1 with integrally formed cooling fins 5 which are bent out of the plane of the disc along the line 6. The individual cooling fins 5 are separated from one another by stamped-out areas 3, from their free end to the electrically effective internal diameter of the short-circuiting disc. <IMAGE>

Title: Stackable shopping trolley with brake device
Inventor: ERTLE KARL ING GRAD
IPC: B62B3/14
Filed: 1983-10-08
Abstract: In known shopping trolleys with brake device, the handle must always be pressed down during travel so that the brakes are not activated.
