Title: Digital display control circuit for electric hot plates - transfers data using multiplexer and grey code to seven-segment converter, controlled by CPU and oscillator
Inventor: FLUHRER HENRY
IPC: F24C7/08
Filed: 1991-05-31
Abstract: The display control circuit transfers data via a multiplexer and a Grey-code/seven segment converter (8) to a parallel-serial converter (6).

Patent DE-4131628-A1 (DE)
Inventor: HENG THOMAS
IPC: F04C13/00
Filed: 1991-09-23
Abstract: The invention concerns a swash pump designed for the transfer of sensitive, time-critical fluids in the food-technology or biotechnology field. All the spaces (11, 15, 16) with which the fluid being pumped comes in contact are included in the pumping path. Since fluid is flowing continuously through the spaces (11, 15, 16) which come in contact with the fluid, the fluid cannot settle in any one place. This makes it possible to clean the pump by simply flushing out the pump with the pump still fitted in place.

Title: Cooling system for engine of e.g. combine harvester or tractor - monitors temperature of airflow and reverses fan action to clear blocked filter if temperature exceeds limit
Inventor: WITTE HARTMUT DIPL ING
IPC: B60H3/06
Filed: 1992-08-27
Abstract: The engine is cooled by a radiator (1) for the engine coolant and with a fan (8) drawing air through the radiator.
