Patent DE-3830375-A1 (DE)
Title: Device for mounting an electronic module on a base part
Inventor: ROHDE WOLFGANG
IPC: H05K7/14
Filed: 1988-09-07
Abstract: A device for mounting an electronic module on a base part is intended to be designed such that the module, on the one hand, makes reliable electrical contact with the mating contact in the base part and such that, on the other hand, good heat transfer is provided from the module to the base part. For this purpose, a tongue and groove connection, in the form of a dovetail, is provided between the module and the base part. The tongue part of this connection is designed as a moving groove block. The module can be firmly clamped against the base part by displacing the groove block within the connection. By using tongue means (spring means) for displacing the groove block, it is even possible to rest the module against the base part in a prestressed manner. The tongue means which move the groove block can be designed such that it is possible to monitor for a desired clamping level and for complete closure of the electrical contacts.

Patent DE-3830683-A1 (DE)
Inventor: BUBIK ALFRED DR
IPC: D21F1/48
Filed: 1988-09-09
Abstract: In a double-screen format for a paper making or cardboard making machine, a suspension derived from the moving sheet is fed between a lower screen (9) and an upper screen (10). Devices act on the screens against an opposing counter surface (1) in order to express the liquid contained in the suspension. The necessary pressure can be applied by means of a system (2) of pressure chambers (a, b, c, d) which open against the counter surface (1) and can be subjected to the action of a pressurized fluid, or by elastic elements on which layers of fluid can be formed. In one embodiment, a band (8) which rotates with the screens (9, 10) is arranged along the openings of the chambers (a, b, c, d) and is impermeable or permeable to the fluid acting in the latter.

Patent DE-3916104-A1 (DE)
Inventor: STAHL HELMUT
IPC: B24B41/00
Filed: 1989-05-18
Abstract: The invention relates to a process for polishing workpiece with a polishing plate (10) rotating about a gyro vector axis (18) and having a plurality of polishing threads (24) distributed around its periphery. Centrifugal force causes the polishing threads (24) to be pushed substantially radially outwards, whereupon their free ends, according to length, strike the surface of the workpiece, which is dipped into the polishing plate (10) for processing, and are drawn thereover. In addition, the polishing plate (10) is rotated about a preferably vertical guide spindle (34) perpendicular to the gyro vector axis (18). Thus the polishing threads are guided under the effect of the gyroscopic couple towards opposite sides obliquely to the guide spindle (34) in two opposite peripheral regions of the polishing plate (10).

Title: Punctiform document scanning for image processing - detects mean value of brightness-proportional image signal for stray light compensation
Inventor: BIRGMEIR KLAUS DIPL PHYS
IPC: H04N1/407
Filed: 1990-02-19
Abstract: The scanning is used for pointwise image processing and an exposure on a photosensitive material by an imaging beam, controllable in its brightness in pointwise manner through an objective lens. For the compensation of stray light, caused by light beam passage through glass, a mean value of each brightness proportional image signal is detected.
