Patent DE-3443924-A1 (DE)
Inventor: MATTHIES KARL-HEINZ DIPL ING
IPC: H04N9/64
Filed: 1984-12-01
Abstract: A circuit arrangement for deriving a control signal from a synchronizing signal whose phase alternates in a predetermined sequence, which control signal is independent of the phase alternation, comprises a reference oscillator (1) which supplies a reference signal, a phase comparator (5) for deriving a phase signal from a synchronizing signal and a reference signal, a correction circuit (22, 26) for generating a correction signal, and a logic combination device (10) for superimposing the phase signal and the correction signal on the control signal. In accordance with the invention control signal variations as a result of the phase alternations in the synchronizing signal are eliminated in that the correction circuit (22, 26) generates a polarity signal which dictates the polarity of the correction signal by comparing the phase of the reference signal and the phase of the synchronizing signal.

Title: Gas/steam compound turbine with two-stage utilisation of waste heat
Inventor: BONGERS HERMANN DIPL ING
IPC: F01K23/06
Filed: 1984-12-06
Abstract: In order to increase the efficiency and to reduce the amount of exhaust gas and the dissipation of heat to the surroundings of gas/steam compound turbines, the necessary combustion air is fed into the compressor of the gas turbine in the preheated state. As a result, the thermodynamic process in the gas turbine runs at an increased temperature level. A greater utilisable temperature gradient is thereby available to the steam turbine. The combustion air can be preheated by heat exchange with the hot exhaust gases, after the latter have given off a proportion of their heat content to the combustion air in a heat exchanger connected between compressor outlet and combustion chamber inlet, with the waste steam from the steam turbine or with both.

Patent DE-3506283-A1 (DE)
Title: Integrable demodulator for digital signals on a carrier, and use thereof
Inventor: BEITNER MICHAEL DIPL ING
IPC: H03K9/06
Filed: 1985-02-22
Abstract: The signal to be demodulated (input signal) passes to a first binary counter (Z). This counter thereupon begins to count, latches itself by means of a logic circuit (V) and reveals this time-delayed event in the output of the demodulator. A second binary counter (Z') to which a reference frequency is applied can also latch itself by means of a logic circuit (V') when a certain count has been reached. However, it is only enabled by the input signal after the input signal has ended and is interconnected with the first binary counter (Z) in such a manner that it reenables the first counter (Z) with its own latching and resets the demodulator output. This results in an output signal which is time-delayed with respect to the input signal but has the same length. Advantages: selective signal detection, good noise characteristic, low-distortion signal processing; monolithically integrated digital receiver circuit. Main field of application: ultrasonic range finding in accordance with the echo method. <IMAGE>

Title: Insulator for receiving a heat-measuring device
Inventor: PRESS VIKTOR
IPC: G01K1/08
Filed: 1985-04-24
Abstract: An insulator (1), preferably with cover (3), for receiving a heat-measuring device has an inner opening (2), into which the measuring device can be fitted. The insulator (1) with its cover (3) consists of an insulating plastic foam (4), for example of polystyrene foam. The inner opening (2) and the underside of the cover (3) are provided with a closed-cell covering of plastic, which is firmly bonded to the insulating foam (4). This can be carried out in particular by applying to the insulating foam (4) an epoxy-foam layer, which for its part has on the outside a closed epoxy skin (6). The epoxy skin (6) can bond well with the epoxy foam (5), whereas the latter in turn enters into a firm bond with the polystyrene foam (4), because it can penetrate partially into the pores of the latter. <IMAGE>

Patent DE-3538995-A1 (DE)
Inventor: FISCHER ARTUR DR
IPC: F16B13/08
Filed: 1985-11-02
Abstract: A method for preventing corrosion of an expandable mounting element which involves introducing a sealing composition into a mounting hole of a support structure first to fill the hole about half-way, then driving an expandable mounting element into the half-filled hole to displace the sealing composition initially against the base of the mounting hole and then up along the surface of the expandable mounting element until the excess emerges out of the mounting hole. A compressible impact device, which has an upper and lower part and a spring part fixed therebetween, is arranged so that an impact tool can be driven against the upper part to fully drive the expandable mounting element into the mounting hole, effecting a sealing compaction in correspondance with the pressure exerted by the spring part. All gaps and cracks are thereby sealed against corrosive media.

Title: Device for remote-monitoring rotary-current points drives
Inventor: LEBEK HANSJOERG
IPC: B61L5/10
Filed: 1986-11-13
Abstract: In order to monitor the two possible drive limit positions, two current direction-sensitive indicators (PPU1, PPU2) are provided which are connected in parallel with one another via exclusion contacts (WL/5, WL/6) of a running-direction selector. A direct voltage monitoring source (60V = ) conducts control potential to the two indicators via the rotary current lines (L1 to L4), the motor windings (W1 to W3) of the drive and its limit-position contacts (AK1 to AK4) if the drive (A) assumes one of its limit positions. In this process, a pole-turning changing switch (WL/1 to WL/4) which is connected into the adjustment and monitoring circuit and has the purpose of prescribing the respective running direction of the drive ensures that the phase position of the control potentials fed to the inputs of the two direct current indicators is the same in both drive limit positions. If the contacts of the running-direction selector switch at the wrong time, the phase position of the control potentials fed to the direct current indicators changes, the fault which has occurred being detectable from the switching state of the indicators. <IMAGE>

Title: Control knob for a latching mechanism (latch, breaker mechanism)
Inventor: BECK MARTIN
IPC: H01H3/04
Filed: 1987-04-02
Abstract: The invention relates to a control knob for a latching mechanism. According to the main Application P 3620289.4, the control knob is designed for increased switching capacity. Under extreme conditions, it can however occur that the stability of the stop for the torsion spring in the lower part of the latching mechanism is not satisfactory. In order to be able to fulfil these conditions as well, it is proposed to provide as stop for the torsion spring 3 a disc 6 which has a radial attachment 61 whose end 63 is bent away by 90@ in relation to the side of the upper part. The disc thereby has a higher stability than the lower part of the latching mechanism. In order to achieve anti-rotation protection for this disc, the latter is provided with a hexagonal cutout 62 which is constructed to correspond with the hexagonal cross-section of the lower part. <IMAGE>
