Patent DE-3912710-A1 (DE)
Title: Supporting structure for soil stabilisation
Inventor: CLAUS HERMANN
IPC: E02D29/02
Filed: 1989-04-18
Abstract: A fill body (A) is closed off by a wall (10) forming its outer skin and consisting of prefabricated elements (9). Projecting through the passage openings of the prefabricated elements (9) are wall posts (7) which are connected via coupling sleeves (5) to grouted bearing piles (1). The prefabricated elements (9) rest on supports (11) which are screwed onto the lower sections of the wall posts (7). The horizontal and diagonal loads coming from the fill body (A) are ultimately absorbed by the wall posts (7) and are transmitted via the bearing piles (1) to the foundation soil. The prefabricated elements (9) stacked one on top of the other without a stagger form continuous vertical joints which connect adjacent wall segments to one another in an articulated manner. <IMAGE>

Title: By=pass system supplying oil and water emulsion - is for mining machine and is actuated by manual opening of stop valve
Inventor: VOSS RICHARD
IPC: B01D35/12
Filed: 1989-05-18
Abstract: Underground mining machinery is supplied with an oil and water emulsion from a supply pipe (3). The supply system is fitted with a by-pass device (1) which includes a stop valve (18) and a non-return valve (2).

Inventor: SCHROEDER KLAUS DIPL ING
IPC: B29C45/77
Filed: 1989-10-03
Abstract: In the case of a process for the manufacturing of moulded parts from plasticisable synthetic material by injection moulding, using a divisible mould, in particular in the processing of curable plastics such as thermoset plastic, in which process, after complete volumetric filling of the mould cavity, during the curing phase the moulding compound is subjected to changes over time in its state parameters such as temperature, degree of crosslinking, pressure or specific volume and these have as a consequence a rising and falling variation in the mould cavity pressure in the interior of the closed mould, it is proposed that the pressure fluctuations in the interior of the mould are counteracted by applying pressure pulses over at least one outer face of the mould, the pressure level of the pressure pulses being set variably, in accordance with the pressure variation of the mould cavity, and automatically acting in the opposite sense to the latter. <IMAGE>

Patent DE-4025497-A1 (DE)
Inventor: ZELENKA THOMAS DR
IPC: H01S5/062
Filed: 1990-08-11
Abstract: The invention concerns a process and circuit for correcting the light-power output of a laser diode. The circuit comprises a generator (2) for generating a driver current (IT) which determines the light-power output of the laser diode (1). The driver current (IT) is modulated by a modulation signal (B). To correct the light-power output, the circuit includes a linear low-pass filter (5) which is acted on by the modulation signal (B) and which approximately simulates the change with time of the internal temperature of the laser diode (1) as a function of the modulation signal (B). The output signal of the linear low-pass filter (5) acts as a driver-current (IT) correction signal (K), thus compensating for the temperature dependence of the laser-diode light-power output.

Title: Magnetic tape cassette equipment with manually reversible drive - has eject key bar terminated in special tongue which effects reversal of tape when partially actuated
Inventor: KUNZE NORBERT
IPC: G11B15/675
Filed: 1990-10-15
Abstract: The end of the eject key bar (302) carries a malfunction tongue (308) which provokes ejection of the cassette when the key is fully depressed. Partial depression of the key allows the reversing clutch to follow a different track (314a) of a multitrack guide (314) so that the reversing lever (384) effects a reversal of the tape drive. Further depression leads the mechanism to follow the main track (314b) back to its starting position with the cassette ejected. ADVANTAGE - Reversal of direction is accelerated by manual pressure on eject key which has wider range of function.
