Title: Method of synchronising/controlling AC voltage-fed converters esp matrix converters, in multi-phase systems
Inventor: HOFMANN WILFRIED
IPC: H03K17/795
Filed: 1997-09-27
Abstract: A process for synchronising and/or controlling converters, especially for forming synchronising signals for matrix converters is described. With multiphase and also distorted sinusoidal input voltages, a direct zero-crossing point detection of the instantaneous value of the phase-to-phase voltages takes place using voltage discriminators. After filtering of the same input voltages, equivalent square wave pulse sequences are formed and thereafter using logical summation, gate signals in the region of the zero crossing points. The zero-crossing point signals, the synchronous pulses derived from them and the gate signals are added to the synchronising signals with precise phase assignment.

Title: Hydraulic bathtub lifter
Inventor: DESCH KURT MICHAEL DIPL ING
IPC: E03C1/10
Filed: 1998-02-04
Abstract: The hydraulic bathtub lifter (27) has a hydraulic three-chamber system separator (1) to prevent heavily soiled water within the lifter hose (26) or piston/cylinder and in the bathtub from being drawn into the clean water supply piping (18). The system separator (1) has a backflow barrier (2,6) between the initial (21) and centre (15) pressures and the back pressure (52) zone.  The force ratios acting on the membranes (11,12) of the release valves (10,14,16) empty the centre pressure zone (15). The closing force is opposed by two opening forces. The closing force at the release valve is the hydraulic initial pressure acting on the membrane (11). The opening force is formed by a reduced initial pressure at least behind the backflow barrier (2) at the initial pressure side, and the spring force (13) of the release valve (14). The release valve (14) is closed only in a setting for a flow through the system separator (1) when the lifter (27) is raised. The centre zone (15) is always emptied when the lifter (27,26) is at rest and when being lowered.

Patent DE-19822543-A1 (DE)
Inventor: STAIGER WOLFGANG
IPC: G06F13/00
Filed: 1998-05-20
Abstract: The method involves allocating tasks originating in one or more client data processing nodes (C2) to the server processing nodes within a group of two or more server data processing nodes (S1-S4) for processing. A client data processing node with a task to assign first selects a server data processing node from the group that is the next node to be selected according to a predefined cyclical sequence. If the selected node declines the task, the client node randomly selects another server node and passes the task to it for processing if not declined. Independent claims are also included for a data processing system, a client data processing node and a computer-readable storage medium.
