Patent DE-3315481-A1 (DE)
Title: Lighting device having an oscillator, a power stage and a gas-discharge lamp, as well as a method for operating a gas discharge lamp
Inventor: KOEHNE RAINER DR
IPC: H05B41/392
Filed: 1983-04-28
Abstract: The lighting device has, in a known manner, an oscillator, a power stage and a gas-discharge lamp. The oscillator generates a radio-frequency signal whose frequency corresponds to a resonant frequency of the ionised gas of the gas-discharge lamp. The radio-frequency signal of this oscillator is amplified in the power stage and is connected via a transformer to electrodes of the gas-discharge lamp, as a result of which an oscillation is maintained in the ionised gas. According to the invention, the oscillator is constructed as a voltage-controlled oscillator, and a feedback loop is provided by means of which a portion of the oscillation voltage of the ionised gas is picked off, rectified and smoothed, and is applied to the oscillator as a frequency-determining control voltage.
Patent DE-3316733-A1 (DE)
Title: Scraper for underground scraper conveyors
Inventor: GARTE RUDOLF
IPC: B65G19/24
Filed: 1983-05-07
Abstract: Underground, scrapers used in double scraper chain conveyors with external round link chains are fitted with shackle type connectors in accordance with DIN 22253. The said shackle type connectors are connected to the scraper by means of screws. The disadvantage is that the screws must have a certain tightening torque in order to avoid bending up of the shackle type connector. The screws are extended even when operating periods are fairly long, causing the shackle type connector to bend up and leading to fracturing of the shackle type connector. This results in conveying stoppages, which are associated with high repair costs. The invention is based on replacement of the screw connection by a chain link, which can accommodate significantly higher tensile forces than the screw. The scraper can be easily fitted and removed from above, by lateral displacement of the connecting chain link. This scraper/shackle type connector joint is a non-resilient, rigid connection which eliminates the bottleneck represented by a screw connection with its associated bore and significantly increases conveying reliability.

Title: Process for producing laminated moulds and components using a vacuum
Inventor: WEIGEL JUERGEN
IPC: B29C33/38
Filed: 1983-05-27
Abstract: The RAPID-O-FORM method according to the invention has as its object, on the one hand, substantially to simplify pattern and mould construction, especially in the field of forming operations, release agents as well as mechanical surface preparation, and on the other hand considerably to improve the surface quality of various materials combinations. In mould construction, for the first time it is possible to dispense with the elaborate forming operation of pattern/master mould/working mould or pattern/working mould/master mould, since any desired number of working moulds can now be produced directly from the pattern. All known grinding and polishing operations are thus also eliminated. It is also novel that a permanent release action is obtained over several thousand demouldings, so that the release surfaces between component and mould do not have to be pre- or post-treated either on one side or the other, so that, if desired, an immediate coating of the component on a smooth, usually glossy, substrate and/or the immediate reuse of the mould are possible. Depending on the materials to be separated, the most varied laminations firmly connected to the mould are available, which are produced almost exclusively under vacuum. The lamination of moulds can also be reversed as regards the release effect between the moulds and components to be produced in that the surfaces laminated during the component production, as primer (tie coat) for coatings and adhesives, ...

Title: Detonating device for a defensive mine
Inventor: J NIEBLER ERICH
IPC: F42C13/00
Filed: 1983-10-27
Abstract: A detonating device (3) for a defensive mine (1) is intended to be able to be designed easily and to lead to triggering of the detonating signal (4) only in response to defined proximity characteristics. To this end, provided on the defensive mine (1) is a sensor which triggers in the event of a change in the field in the effective region in the vicinity of the mine (1). The change in field caused by a person approaching the mine (1) may, for example, occur in the influencing of the earth's magnetic environmental field or of a high-frequency field emitted by the mine (1). However, the sensor preferably responds to a change in the dielectric or resistive properties as a consequence of a pressure stress when a person steps on it. To this end, the sensor is constructed as a cable (5) which can be spun out from the mine (1) and has two conductors (12, 13) between which pressure-dependent "insulation" (14) is arranged; its change in time can be evaluated in order to avoid atypical pressure stresses causing triggering of the detonating signal (4). A plurality of ejection devices (17) can be provided for laying out a plurality of such cables (5) which are operated by a time-delay initiator (16) after the mine (1) has been positioned. <IMAGE>

Title: Screw-union packing
Inventor: DAUME ACHIM DIPL ING
IPC: F16L23/12
Filed: 1983-11-15
Abstract: Corrugated tubes, to some extent of double-walled design, are frequently used in line construction for safety reasons, for better insulation or also for force compensation. In this case, it is difficult to seal two pipes whose ends abut against one another and to seal double-walled pipes whose intermediate space is divided into pressure spaces at different pressure levels. In order to solve these problems, a seal packing is proposed which consists of two bushes which are arranged on the corrugated pipe, can move with respect to one another and engage in one another. There is an annular space which surrounds the corrugated pipe between the bushes, for holding a sealing compound.

Title: Test equipment for investigating electrically conductive test parts
Inventor: NEUMAIER PETER DIPL ING
IPC: G01N27/90
Filed: 1984-03-22
Abstract: Multi-phase excitation of eddy-current transmitters can be used in eddy-current test equipment for the purpose of influencing the signal behaviours differently in the complex plane of interference and useful signals. A simple capability for multi-phase excitation of an eddy-current generator (10) is described, according to which the terminals of a compensation winding (20) are terminated with an impedance (44). The alternating current which flows in the compensation winding (20) and is induced by the excitation current IE in this way receives a phase angle which deviates from the excitation current IE of the excitation winding (16), without a current with a deviating phase angle having to be supplied from the outside. Possibilities for controlling the compensation current are indicated.   <IMAGE>
