Patent DE-4204465-A1 (DE)
Title: Ratcheted system for rotary switch - has different turning resistances within programs or switching steps, used e.g. for washing machine
Inventor: BAUER WOLFGANG
IPC: H01H19/11
Filed: 1992-02-14
Abstract: The ratchet system for a rotary switch has differing resistances to be overcome when turning it into a new setting, in at least two switch zones and/or switching steps. Specificallly, the spring-loaded ratchet projection has an adjustable spring tension according to the angular position. The ratchet projection (18) is at a yoke-type ratchet (16), supported on both sides by a pressure spring (20, 22). According to the angular setting, a limit stop makes one spring inactive. USE/ADVANTAGE - The rotary switch is for appliances such as washing machines, where the switch sets a program according to the type of washing action and the nature of the load. The different resistance experienced when turning the switch from program to program, or within each program, helps the user to recognise the setting as the switch is turned.

Title: Valve timing gear for increasing the intake temperature for the cold starting of internal combustion engines
Inventor: KUHN PETER PROF DR ING
IPC: F01L13/00
Filed: 1993-03-18
Abstract: The inlet valve of an internal combustion engine is actuated with an adjustable lift by means of a mechanism in which a cam together with one or more intermediate elements and an output element forms a kinematic chain. If the valve lift is adjusted to the value zero by the kinematic chain, the cam engages with the output element, bypassing the kinematic chain, and still briefly opens the valve at the piston bottom dead centre. In an intake process controlled in this way, the cylinder charge is heated in cold starting.

Title: Hot gas motor working on Stirling motor principle - has conventional rotating piston air engine, compressor, and heat exchangers, connected by common shaft to form closed gas circuit
Inventor: WEISS GEROLD
IPC: F02G1/043
Filed: 1993-05-27

Title: Cleaning deposits from inner surfaces of well pipes - using three simultaneous processes, fluid shock wave from discharge across spark gap, ultrasound wave and water jet
Inventor: PRODINGER KARL DIPL ING DR
IPC: B08B9/027
Filed: 1993-06-30
Abstract: To loosen deposits adhering to surfaces, especially inner convex surfaces of bodies in contact with fluids, shock waves in the fluid medium are used, generated by electric discharge across the spark gap. The shock waves are focused by a shaped reflector. At the same time, the deposits are subject to ultrasound from a siren. Finally, a water jet is also sprayed onto the surface in question. The electric discharge comes from a circuit with high voltage generator, a capacitor bank and a switch. Using water or oil as the fluid medium, a very high temperature is created in the spark gap giving a pressure wave with a steep rising flank. ADVANTAGE - Highly efficient.
