Title: Arrangement for length compensation for precision level staffs
Inventor: DONATH BERND DR
IPC: G01B5/00
Filed: 1987-08-08
Abstract: The invention relates to an arrangement for length compensation for precision level staffs by removing the reaction on the bracing force of the high-precision scale carrier in the staff body which occurs when the precision level staffs are loaded due to temperature or humidity. The error in length which occurs due to these loadings is removed at the same time. This is achieved by bracing a scale carrier (4) in a staff body (1) by means of a lever (3) through spring force in such a manner that the pivotal point B for a spring (5) is provided on the lever (3) between a bearing point A of the lever (3) and a suspension point C of the scale carrier (4). For a complete length compensation, the relationship <IMAGE>  must be satisfied. <IMAGE>

Patent DE-3736956-A1 (DE)
Inventor: EUL WILHELM
IPC: B22D11/14
Filed: 1987-10-31
Abstract: The outflowing casting metal on the path to solidification is no longer subjected to reoxidation and degassing of the casting metal in case of unkilled melts and can immediately be performed ahead of the casting process in a method for continuous casting of metal strands from high-melting metals with cross-sections close to the end dimensions according to the principle of the communicating pipes, and further a temperature and analysis correction can be performed. These conditions are fulfilled by pressing the casting metal from a higher disposed storage container through the communicating channel pipe (8) into a pressure vessel (13) with a gas dome (20), where the casting metal is further transported through an immersion pipe (14), which immerses into the casting metal through the gas dome, into a substantially vertically oscillating independent continuous casting die (15) and where the casting strand formed is deflected in an arc from the vertical direction into the horizontal direction and is withdrawn.

Title: Process for the production of duplication pieces of a master disc
Inventor: THEILE GUENTER
IPC: G11B7/26
Filed: 1988-12-15
Abstract: In order to produce duplicates of a master disc on which digital signals, in particular digital sound signals, are recorded, the invention uses, as the master disc, an X-ray mask in which either only the signal information-carrying areas or only the signal information-free areas are transparent to X-rays. A base disc provided with a photoresist coating is positioned beneath the X-ray mask. The photoresist coating masked by the X-ray mask is exposed to X-rays having an intensity sufficient to cure the areas of the photoresist coating exposed to X-rays. The uncured areas of the photoresist coating are removed chemically, and the cured areas of the photoresist coating which remain and the bared areas of the base disc which lie in between are provided with a metallic, highly reflective coating. A protective coating of varnish is applied to the metallic coating. In this way, the digital signal pattern can be transferred directly from the master disc to the duplicate without mechanical means, which shortens the process time and increases the transfer reliability without the risk of producing rejects.

Title: Pneumatically operated central locking system for cars - has spring-loaded catch to hold mechanism in unlocked position
Inventor: SEITZ RAINER
IPC: E05B77/50
Filed: 1989-05-16
Abstract: The motor vehicle is provided with a centrally controlled locking system for the doors, boot lid, and bonnet. Each lock is actuated by means of two rolling diaphragms (10,11) installed in chambers (4) and (5) respectively which are mounted side by side. The diagram shows the lock mechanism in the locked position.  The lock is released either by actuating an outside lever (24) or an inside lever (25) which set the pump (8) operating. This pump draws air from the chamber (5) so that the rolling diaphragm moves upwards and swings the anti-theft lever (17) upwards.  The rod (27) attached to the diaphragm (11) opens the valve (9) so that air is drawn from the second chamber (4) and the second diaphragm moves upwards together with the rod (12) to allow the security lever (14) to move upwards. The mechanism is held in this position by a spring-loaded ball catch (20). USE - Central locking for motor vehicles.

IPC: H01G9/028
Filed: 1990-01-19
Abstract: The Ta-capacitors with semiconducting cathode feature a Ta-foil or sheet which has on one or both surfaces Ta powder attached by sintering and an organic semiconducting cathode. The Ta-powder layer is pref. 0.01-0.5mm thick, esp. 50-100 micron. The carrier is pref. etched Ta-foil or sheet. The organic semiconductors used as cathode are pref. a TCNQ-complex, polyethylene, polypyrrole, polyaniline or polythiophene. The foil or sheet can be folded or spiralled and the cathode material is applied after the final shape has been achieved. Contacts can be made by including an Al-foil in the windings. USE/ADVANTAGE - The use of the modified foil or sheet results in a large are Ta-electrode which has a reduced penetration depth compared with a current sintered powder electrode. This allows easier penetration by the cathode material. The resulting electrode area is much larger than can be achieved using etched foils.
