Title: Door lock for household appts. e.g. dishwasher - has handle which must be slid sideways to release lock arm so that lock fork drops
Inventor: WENDISCHHOFF HARTMUT
IPC: E05C3/24
Filed: 1992-09-30
Abstract: The lock acts as a safety lock. The pivoted handle to open or close the door is slidable sideways inside the recess. To open the door, the handle is slid sideways out of its rest position. In its rest position, it prevents the door from being opened because a lever arm holds the lock fork onto the casing lock bolt. When the handle slides sideways, the lock arm drops, releasing the lock fork. With the door open, the handle automatically returns to its rest position and the lock fork drops into a detent in the lock arm, thus being held in the "unlock" position. ADVANTAGE - Safety look which prevents accidental opening and is child-proof.

Title: MOS memory device for serial information processing
Inventor: LINGSTAEDT ERNST ING GRAD
IPC: G11C19/28
Filed: 1993-02-19
Abstract: The invention relates to an MOS memory device for serial information processing, in particular a shift-register stage with an EEPROM cell which has a floating-gate transistor. In the prior art, the gate electrodes of all the floating-gate transistors of a memory device are at the same potential. This has the consequence that, for complete programming, two programming cycles have to be performed, this entailing high electrical power consumption. According to the invention, the drain electrode of the floating-gate transistor is connected to its gate electrode via an inverter stage. As a result, the overall programming time is halved in comparison with the prior art, and consequently so too is the overall electrical power for programming.

Title: Method and device for dynamic internal pressure testing
Inventor: BAUMGARTEN MANFRED
IPC: G01N3/36
Filed: 1993-07-30
Abstract: The invention relates to a method for dynamic internal pressure testing of closable hollow bodies, in which the hollow body to be tested is exposed via a converter (intensifier) controllable by an adjustable function generator and a valve in pulse fashion by a liquid pressure medium having a pressure pulse with a low fundamental frequency and a large amplitude and with a higher beat frequency and low amplitude. In order that the pressure convertor which is to apply a high working volume need not simultaneously also be operated with a high frequency, the function generator controls two separate pressure convertors with volumes of different size, the pressure convertor with the larger volume produces the lower fundamental frequency with the large amplitude and the pressure convertor with the small volume produces the higher beat frequency with the lower amplitude for the pulsed pressure.
