Patent DE-4241231-A1 (DE)
Title: Contact belt gear box with periodically changing translation - has two or more discs with fixed rotary axes looped by contact belt of constant length in each position of discs.
Inventor: RAHE WILFRIED
IPC: F16H35/02
Filed: 1992-12-08
Abstract: The drive or driven disc or both have an active radius which can change over the circumference to produce the variable translation. The circumferences of all the discs (1,2,3) are in a whole number ratio to each other. The generally non-circular shape of the discs is chosen so that the length of the contact belt member (4) is the same in each position during synchronous rotation of the gear. The gearbox can comprise two eccentrically mounted circular discs (1,2) and a third non-circular disc (3) which holds the length of the contact belt constant. USE/ADVANTAGE - Gearbox giving periodically varying drive rate for various types of drive is of simplified design requiring no maintenance.

USE/ADVANTAGE - Esp. for use for monitoring a reaction in which hydrogen is produced or released eg pressure measurement in accumulator cells with negative storage electrode or establishing hydrogen sorption curves. Its sensitivity can be adapted to the application.

Title: Hydraulic control device
Inventor: SANDAU HARTMUT DIPL ING
IPC: F15B13/04
Filed: 1993-04-23
Abstract: The hydraulic control device for a double-acting operating cylinder (17) having two pressure spaces (21, 22) has a control valve (14, 30; 24, 33) assigned to each of these pressure spaces for loading and relieving the relevant pressure space. Extending of the operating cylinder is carried out via a pressure balance (11) which is connected to the pump pressure line (13) and is assigned to the control valves for filling the pressure spaces. In a specific operating state, the so-called biased piston, with pressure medium neither flowing to nor from the operating cylinder, the pressure balance is set via a change-over valve (37) by means of the higher of the two pressures in one of the pressure spaces such that it is only used for pressure regulation and ensures that virtually no higher pressure is produced in the pressure space (22) on the piston-rod side than in the bottom-side pressure space (21). The result is a more reliable operation of the hydraulic system. <IMAGE>

Title: Public lockable bicycle stand
Inventor: NAJORK ANDREAS
IPC: G07C9/00
Filed: 1993-05-08
Abstract: The connection of bicycles to bicycle stands actually necessitates thick and long chains which, however, are difficult to transport. Lockable standing places are known (in the form of cages) only for a circle of users which, in each case, is restricted. The present invention will therefore offer a lockable bicycle stand for an open circle of users. What is proposed is a stationary bicycle stand with a fixedly installed thick steel rope (3) which can be used by any subscriber for connecting the bicycle. For this purpose, he must insert (any) identification card (7) into a reading head (8) provided. Up to this moment, the code on the card can be any code, but is stored. Only when the same card is inserted again does the magnetic lock (6) release the rope again. Furthermore, for alarm protection, the integration of a wire or of an optical waveguide into the steel rope is proposed. The bicycle stand presented can be erected in the form of posts instead of or in addition to the otherwise conventional bicycle stands. Because identification cards can be purchased freely, it can be used by anybody. <IMAGE>

Title: Length measuring arrangement
Inventor: MUELLER THOMAS DIPL ING
IPC: G01D5/26
Filed: 1993-05-25
Abstract: The invention relates to a length measuring arrangement for detecting the position of a sample (device under test, test specimen) in a measuring direction, which has a detector arrangement and a beam generating device. The position of the point of incidence (impingement) of the beam on the detector arrangement is a function of the position of the sample in the measuring direction. The detector arrangement consists in accordance with the invention of two groups of detectors, which are arranged in an alternating fashion in the longitudinal direction of the detector device. Each group of detectors is connected on the output side to one signal combining circuit each for the purpose of generating a pulse train when the specimen moves. The outputs of the two signal combining circuits are connected to an evaluation and counting device which counts the pulses of one of the two pulse trains, and the counting direction thereof is a function of the mutual phase angle (phase relation) of the two pulse trains. The device according to the invention can be used, e.g., to monitor chip contacting in semiconductor fabrication.
