Title: Elastic matrix mfr. - for travelling plates with back filling of specified heat conductive plastics
Inventor: RAUSCHER WOLFGANG
IPC: B29C33/56
Filed: 1989-05-18
Abstract: Artificial travertine tiles for wall and floor lining can be made by using a ram (24) with a metal mask (22) of sprayed aluminium in the lower part of a mould (26), presenting a negative of the desired surface. The space between (24) and (26) is filled by a suitable rubber or plastic mixture to produce a mould. The rear (28) of the mask (22) is backfilled with a heat conductive casting resin (30), e.g. with aluminium particles at a rate of 85-95%, to a depth (DH) of three to five times the depth of the impressions of the mask. An intersecting grid (32) of steel strips (38,46,48,50,52,54,56,58) is also filled with the same casing resin. A steel plate (36) is used to transfer the force. ADVANTAGE - This provides a cushioning padding and  distributes the press force equally.

Title: Controllable coupling for the mechanical decoupling of shafts driven in parallel by motor
Inventor: PARDUBITZKI RICHARD DIPL ING
IPC: B65H3/06
Filed: 1989-05-24
Abstract: To transmit a motor torque, there are two interconnected torque-receiving hubs (70, 71) of the controllable coupling (7) rotatably mounted on each of the shafts (61). The motor torque is here transmitted to the shafts (61) in a manner conventional in commercially available products by way of a detent mechanism (72). The detent mechanism (72) is connected to a first hub (70) of the coupling, which hub has, in the circumferential direction, a guide channel (FKn) with a width that changes in the axial direction acting as a control cam. Also provided is a guide stud (730) which is arranged in a second hub (71) of the coupling and, when the first hub (70) and the second hub (71) of the coupling are connected, engages in the guide channel (FKn). The guide channel (FKn) contains two detent recesses (RN1, RN2), in which the guide pin (730) engages when defined rotations of the second hub (71) of the coupling occur and, depending on the direction of the motor torque, transmits this via the detent mechanism (72) to the shaft (61). <IMAGE>

Patent DE-4004135-A1 (DE)
Inventor: KOBLITZ RUDOLF DR ING
IPC: G05F1/56
Filed: 1990-02-10
Abstract: Phase shifts occur at higher frequencies in integrated circuits which include an amplifier for analog signals, e.g. in control circuits. To prevent uncontrolled oscillations thus produced, the phase and amplitude response is altered with the aid of a frequency response compensation capacitor. The value of this capacitor is proportional to the amplification. However, integrated capacitors require a large chip area. Due to the addition of an unregulated control value (76) approximately corresponding to the set value (79), the error amplifier (71) of the control circuit can be operated with lower amplification. The feedback can thus be reduced and in consequence the size needed for the frequency response compensation capacitor and the chip area required therefor can also be reduced. For integrated analog amplifiers.

Inventor: BAUSCH JOACHIM DR ING
IPC: H01B5/10
Filed: 1990-02-17
Abstract: The cable structure consists essentially of all the wires (1) of the cable or only those of the individual layers having the same diameter, and the small optical waveguide tube (5) being arranged around the core, preferably in the first layer (3), instead of a wire consisting of high-tensile material. The number of optical information lines in the cable is increased if a plurality of high-tension wires of the cable in a symmetrical arrangement are each replaced by a small optical waveguide tube (5). Furthermore, the protection of the metallic small optical waveguide tube in the cable is increased by a sleeve (8) which protects it against abrasion and/or corrosion. Such an optical waveguide overhead cable is used mainly as an optical waveguide earth cable in high-voltage overhead networks. <IMAGE>
