Title: Spring system for wheel support on motor vehicles
Inventor: RUNKEL WALTER DIPL ING DR
IPC: B60G17/056
Filed: 1991-09-07
Abstract: The hydraulic medium, during springing in and out, flows backwards and forwards via a hydraulic connection between the spring legs (2,4) and at least one hydro-pneumatic spring accumulator (22,20) contg. a compressible medium. The spring accumulator, by compression of the compressible medium, produces a hydraulic pressure, which affects the force of the spring legs via the piston activation (8).     During the springing out of the spring legs, two at least timewise varying hydraulic pressures prevail in the legs and in the spring accumulator, whereby the closure and opening of the connections (16,18) between the spring legs and the spring accumulator are automatically controlled by the difference in the hydraulic pressures (p1,p2) in the legs and the accumulator.

Title: Synchronising incoming data words by pulse train - continuously supply system pulse of oscillator at reception side to delay chain consisting of delay circuits in series
Inventor: HEINECK FRANK
IPC: H04L7/033
Filed: 1991-09-30
Abstract: The clock synchronisation of incoming data words, consisting of a serial bit train, is achieved by using a preset system clock of the receiver. Each data word is introduced by a start bit.

An incoming start bit (SB) releases the output of that delay circuit, at which the system clock is applied at that time point, after a certain preset delay time. Pref. the outputs of all other delay circuits are blocked after the release of a certain delay circuit output. ADVANTAGE - Synchronised clock is started only after arrival of start bit and defined time period for certain phase shift.

Patent DE-4244550-A1 (DE)
Title: Device for variably controlling valves in IC engine
IPC: F01L13/00
Filed: 1992-12-30

Title: Fine synthetic yarn winding - using variation of angle on a time basis to form a cylindrical cross-wound package
Inventor: SCHIPPERS HEINZ DIPL ING DR IN
IPC: B65H54/06
Filed: 1993-02-04
Abstract: A process to wind a yarn on to a crosswound reel, in which the spool-factor is defined as the quotient of spindle revolution and traverse rate, which, in the course of winding is reduced is claimed. The traverse rate from a max. is reduced in course of time to a predetermined lower level. This redn. ensues in a certain space of time, and for a predetermined period, regardless of the spool-factor. The procedure is pref. applicable to smooth synthetic filament formed into crosswound reels of a cylindrical shape. The traverse rate determines the angle of wind. The greater angle forms a firmer wind, but has to be fluctuated to satisfy other conditions of winding. The fluctuation of the max. permitted traverse rate, and the relative angle, is to create a stable cylindrical package. the lower traverse rate ensures that the angle is not held at a normal to the reel, which would result in sloughing off, ribboning and other faults which may make the reel unusable. USE - In addn. to observing the methods to avoid ribboning, the procedure ensures axial stability, sloughing off is prevented, and a firm package at the ends is maintained.

Title: Integral light transmission and reception module - has light detector and emitter connected via opto-electric converters and hermetically sealed in unit
Inventor: ISHIZUKA KOHEI
IPC: H01L31/12
Filed: 1993-03-08
Abstract: The module has a first optical fibre (106) to receive a first external optical signal and a second optical fibre (102) to send out a second optical signal. An opto-electric converter connected to the first fibre converts the first signal to an electric signal. A light detector module holds the converter and hermetically seals a connector between the converter and the first fibre. A receiver circuit reproduces data from the electric signal. A transmitter circuit converts data to be transmitted to an electric transmission signal. A light emitter connected to the second fibre and driven by the transmission circuit converts the transmission signal to a second optical signal. An emitter module holds the emitter and seals a connection between it and the second fibre. The circuits are mounted on a p.c.b. The modules and p.c.b. are sealed in a unit. ADVANTAGE - Ensures integration and prevents leakage of signals between reception and retransmission. Suitable for miniaturisation.
