Patent DE-10345497-A1 (DE)
Title: Oszillatorschaltung, insbesondere für den Mobilfunk
Inventor: HERZINGER STEFAN
IPC: H03K5/13
Filed: 2003-09-30
Abstract: In einer Oszillatorschaltung ist ein wertdiskreter abstimmbarer Oszillator (4) mit einem über eine Schalteinrichtung (5) zuschaltbaren Abstimmglied (6) vorgesehen. Eine mit dem Ausgang (41) des Oszillators (4) verbundene Gleichrichterschaltung (8) bildet aus dem Oszillatorsignal ein Taktsignal. Weiterhin enthält die Oszillatorschaltung eine Phasenverzögerungsschaltung (9) mit einem Schalteingang (91), mit einem Taktsignaleingang (97), der mit dem Ausgang der Gleichrichterschaltung (8) gekoppelt ist, und mit einem Schaltausgang (96), der mit der Schalteinrichtung (5) gekoppelt ist. Die Phasenverzögerungsschaltung (9) weist eine Vergleichsschaltung (94) zum Vergleich einer Phase des am Signaleingang anliegenden Taktsignals mit einer Referenzphase auf. Sie ist zur Abgabe eines Schaltsignals nach Anliegen eines Aktivierungssignals am Schalteingang (91) und nach einer Übereinstimmung der Phase des am Signaleingang (97) anliegenden Taktsignals und der Referenzphase ausgebildet. Dadurch wird der Schaltvorgang so lange verzögert, bis die Sprungantwort des Ausgangssignals des Oszillators keinen Phasensprung im Taktsignal verursacht.

Patent DE-19512623-A1 (DE)
Inventor: KOLBE ALEXANDER
IPC: B60T8/00
Filed: 1995-04-05
Abstract: For the purposes of vibration damping in the drive system of a vehicle fitted with a regulating system (ABS, ASR, etc.), circumferential rotary vibrations in the wheels are detected by evaluating the rotational behaviour of the individual wheels. The rotary vibrations are damped by injecting the braking pressure or modulating the braking pressure injected to limit the slip in the individual wheel brakes depending on the amplitude and phase relation of the rotary vibrations.

IPC: F01L1/02
Filed: 1995-10-14
Abstract: A take-up device for the chain or belt of an internal combustion engine, for example of the camshaft drive, has a cylindrical take-up housing (2) that contains a piston (1) stressed by a compression spring (13). Housing (2) and piston (1) can slide in the axial direction in relation to each other.

Title: Automatic door closing system
Inventor: ZIMMERMANN JOACHIM
IPC: E05F1/12
Filed: 1995-10-21
Abstract: The door can be opened and closed by e.g. an electric motor or by a force accumulator such as a spring. The door hinges have slides which introduce friction into the door movement. One end of the slide is attached to the door frame, the other end moves between two plates. The slide (41) can incorporate leaf springs (61) which press a plate (65) against a fixed plate (62) with ridges (62c). The plate (65) rides over the ridges while compressing the springs (62). The friction exerted by the arrangement is larger while closing of the door. Alternatively the resistance can be introduced by a fluid filled cushion, a buffer body or similar device.

Patent DE-19602596-A1 (DE)
Inventor: KLINGENBERG WOLFGANG
IPC: H04Q11/04
Filed: 1996-01-25
Abstract: The method follows-up any connection (15) of an appliance (1) to the bus line (5) linking all such appliances with a control centre (10), by transmission of characteristic data such as the appliance's type number and serial number from its memory (40) with the aid of bus logic (75). The control centre forwards this information via modems (105,110) and a telephone network (25) and a customer service processor (30) linked to a database (35). The method then reads operational data for transmission to the control centre. The memory preferably contains a telephone number for access to the processor. The modems are unnecessary if the network is a digital one with appropriate interfaces.
