Title: Electronic starter with thermal switching for fluorescent lamps - safeguards MOSFET against overheating by discharging or short-circuiting gate-to-source capacitance at excessive temp.
Inventor: HERFURTH MICHAEL DIPL ING
IPC: H05B41/285
Filed: 1991-07-25
Abstract: A half-bridge inverter has a power MOSFET (8, 9) in each branch which carre is a multiple of the lamp current during the striking phase.

IPC: C14C15/00
Filed: 1992-03-30
Abstract: In the appts. to transport and preserve skins and pelts, the preservation of the unsalted skins is within a hermetically sealed vessel directly after skinning.

Beating surfaces for the coolant air are on the outer sides of the cones. ADVANTAGE - The system gives a constant preservation action on the skins, with a cool temp., from the slaughterhouse to the processing plant, without allowing the skins to stick together.

Patent DE-4243549-A1 (DE)
Inventor: SCHULZE WIELAND
IPC: B01J2/20
Filed: 1992-12-22
Abstract: In the method described, a homogeneous pre-mix is extruded at high pressure through nozzles (2) to give a continous extrusion. The extrusion emerging underneath the essentially vertical nozzles (2) is chopped at right angles by a rotating chopper blade (4) to the specified length.

Title: Adjustable vibration drive with two unbalanced bodies e.g. for filter or conveyor - uses two AC drive motors coupled to two different AC systems, with different frequencies or phase, one of which is produced by semiconductor switch.
Inventor: BALD HUBERT DIPL ING
IPC: G01P3/56
