Patent DE-3327542-A1 (DE)
Title: Telescopic shore
Inventor: STRAHL GERHARD
IPC: E04G25/06
Filed: 1983-07-30
Abstract: Telescopic steel-tube shore consisting of two tubes and intended for shoring up building parts, trench walls and for general supporting purposes. To avoid the disadvantages of commercially available shores, an expensive threaded lock susceptible to failure, a bored upper tube susceptible to buckling, and further expensive movable parts, there are no longer any movable parts on this novel shore. A steel bolt which is welded in the lower part of the upper tube and fixed to a supporting adjustable ring around the lower tube, engages in a tooth slot in the lower tube and permits vertical adjustability of the shore within seconds. In accordance with current regulations, the upper tube is unable to fall out of the lower tube, and there is no risk of accident when the upper tube falls into the lower tube. The upper tube no longer has any bores, and thus retains its full loadability; the shore can be employed in both directions vertically and also as a sloping shore; it can also be subjected to tension. For manufacture, only commercially available, standard steel tubes and small components are required.

Title: Device for illuminating an at least partially transparent display window
Inventor: OELSCHLAEGEL FRIEDER
IPC: G02F1/13357
Filed: 1983-12-03
Abstract: A device for illuminating a partially transparent display window, such as a LCD display or the like, comprises a transparent light-guiding plate behind which the light sources, in particular light-emitting diodes, are laterally arranged. The light emitted from these light-emitting diodes enters the light-guiding plate from behind via unsilvered strips, is reflected at silvered lateral surfaces which are inclined with respect to the surface of the light-guiding plate, impinges on the silvered rear of the light-guiding plate and is reflected there once again. From the silvered rear of the light-guiding plate, which in order to obtain diffuse reflection is advantageously roughened or provided with a grainy structure, the light, which is now uniformly distributed, passes from behind into the display window. This design has the advantage that there is no need to provide light sources directly behind the display window, and that a very uniform illumination of the display window is produced. The unit, consisting of display window, light-guiding plate, printed circuit board and contact rubber strip, is held together by a metal frame. The light-emitting diodes used as light source can be arranged laterally in recesses in the printed circuit board.

Title: Circuit for controlling the power of high-frequency transmitters
Inventor: THALHAMER HELMUT
IPC: H03G3/20
Filed: 1984-09-14
Abstract: The invention relates to a circuit for controlling the power of radio-frequency transmitters by means of a control loop, comprising a controllable amplifier (V1), an RF power amplifier (V2), a directional coupler (RK) and a rectifier (G). Such a circuit is to be constructed in a particularly simple way. For this purpose, the invention envisages that the output voltage of the rectifier (G) is compared as a controlled variable (x) with a reference variable (w), output by a setpoint generator, and the system deviation (xw) thus obtained is used to drive a control amplifier (IR) operating as an integrator. The control amplifier (IR), to which a further defined voltage (z) is fed, supplies the manipulated variable (y) for the controllable amplifier (V1). The reference variable (w) is obtained from a signal for the transmitting power setting of a data bus and passed via a logic part (L), a D/A converter and a low-pass filter (BF) to the comparison point. <IMAGE>
