Patent DE-3402040-A1 (DE)
Title: Fastener device with locking pins supported by a helical compression spring in an oblique guide groove
Inventor: SCHNEIDEREIT ALFRED
IPC: A44C5/20
Filed: 1984-01-21
Abstract: In most of the fasteners on the market today, leaf springs or U-shaped springs are used which are subjected to a high risk of breakage. A part mounted on the construction also usually has to be moved in order to unlock the fastener. All these compromises are eliminated in the present construction since a helical spring is used and no external intervention is required for opening. Additionally, the construction is built around a support bush which supports all the important elements. The use of a central ring makes embedding possible in any shapes and materials of the housings, freely or coupled thereto. By varying the shape of the groove of the fastener inserter and of the spring, any desired fastening and holding characteristics can be achieved.

Title: Screening housing for circuit boards
Inventor: EBERT ALFRED DIPL ING
IPC: H05K9/00
Filed: 1984-01-26
Abstract: The invention relates to a screening housing which consists of two sheet-metal parts (1, 2) which are constructed on in each case two opposite side walls (3, 4) which each have a guide rail (6, 7) which is of U-shaped cross-section and is open inwards, it being possible to push the second sheet-metal part (2) by means of its guide rails (7) onto the guide rails (6) of the first sheet-metal part (1), forming a positive lock. In addition to connecting the sheet-metal parts, the guide rails (6, 7) are used for firm retention of the circuit board (8), heat dissipation and for insertion of the housing into a plug-in rack (15). The two-piece construction makes it possible to attach screening metal sheets to the second sheet-metal part for the purpose of screening individual circuits from one another. The screening housing according to the invention is suitable for RF assemblies. <IMAGE>

Title: Circuit arrangement and method for printing video images
Inventor: SCHROEDER WOLFGANG DIPL ING
IPC: G06K15/00
Filed: 1984-05-12
Abstract: The circuit arrangement contains a memory (18) for digitised pixel signals of which the video image is composed, a printing head which prints the video image as a dot matrix and a controller by means of which the memory is read and the printing head controlled. In order to reduce the memory requirement, memory control signals are produced in first switching devices (16, 23), which memory control signals are matched in time to the periodically recurring video signal, and by means of which in each case only the pixel signals which form a subsection of the video image are written into the memory (18) and read out therefrom. The subsequently produced control signals for the memory are delayed with respect to the video signal frame clock by means of a second switching device (28), such that the pixel signals are written into the memory (18) and are read out therefrom which form the respectively next subsection of the video image. <IMAGE>

Patent DE-3436579-A1 (DE)
Title: Device for connecting two pipe ends
Inventor: WEINHOLD KARL DIPL ING
IPC: F16L23/032
Filed: 1984-10-05
Abstract: The invention relates to a device for connecting two pipe ends, one of which is provided with a plug part and the other is provided with a sleeve part. Said parts each have an outer annular collar. A clamp which surrounds the sleeve part and the plug part has lateral flanges which engage over the annular collars. Sealing takes place with the aid of annular seals and, possibly, also of additional supporting rings. Hydraulic units which are connected to the pipeline can produce very high shock loads which lead to damage to the rings. According to the invention, damage can be prevented if an intermediate layer, which is constructed in an elastically sprung manner in the axial direction, especially a helical spring, is arranged between a flange of the clamp and the annular collar behind which it engages.

IPC: B41F31/14
Filed: 1985-01-29
Abstract: The amount of travel and the phase of axial reciprocation for sets of distributing rollers provided on each of at least two inking units of a rotary printing unit are independently adjustable from a central location. For each of the inking units, one eccentric drive adjustable in reciprocating phase and in the stroke or amount of travel is connected to the end portion of an impression cylinder twice the size of associated plate cylinders so that the axial reciprocating movements of the distributing rollers are derived in synchronism with the rotation of the impression cylinder and in a ratio of 1:2 to the rotation of the associated plate cylinders. In one embodiment, a single bolt clamps the two eccentric drives one on top of the other to the end portion of the impression cylinder. In another embodiment, the two eccentrics drives are concentrically arranged in ring-fashion to permit separate clamping and unclamping of each of the four independent adjustments of the amount of travel and phase of reciprocation.

Title: Multi-position illuminated switch on motor vehicles
Inventor: SPAZIERER HUBERT
IPC: B60Q3/04
Filed: 1985-09-17
Abstract: The invention relates to a multi-position illuminated motor-vehicle switch having a plurality of symbols which are allocated to the switching positions on a switching shaft, are arranged on a display area and can be illuminated by a light source which is arranged in a fixed position. During its movement into the switching positions, the switching shaft can drive a light conducting body which runs with a first end close to the side of the display area facing away from an observer and has an extent which corresponds at least approximately in terms of area to the area extent of the individual symbols, and which engages over the light source, like a cover with a second end, in all switching positions. In consequence, the symbol which is allocated to the selected switching position can be illuminated very brightly. The other symbols are illuminated uniformly brightly by the light which emerges between the ends of the light conducting body, but are darker than the symbol which is to be allocated to the selected switching position. Correct identification of all switching positions is thus ensured, the respectively selected switching position being emphasized in a high-contrast manner.

Title: Multiplexing and nB/mB coding arrangement
Inventor: FIEDLER UDO DIPL ING
IPC: H04L25/49
Filed: 1986-03-13
Abstract: In this arrangement, a number of binary input signals are synchronised and are subjected to nB/mB coding before the multiplexing. To be able to dispense with a frame structure in the multiplexing and, nevertheless, have the possibility of demultiplexing at the receiver end, the procedure is such that a separate nB/mB coder is provided for each of the synchronised input signals, that one of the nB/mB coders contains a device by means of which, induced by a control signal, code errors are inserted into the coded input signal in such a manner that the information content of the input signal is not corrupted during this process and that the multiplexing is carried out by a parallel/serial converter.
