Patent DE-3633905-A1 (DE)
Title: Drive circuit for the magnet drive winding of a small DC contactor
Inventor: MUELLER KARL ING GRAD
IPC: H01H47/22
Filed: 1986-10-04
Abstract: A drive circuit for rectifying an AC supply voltage for a magnet drive winding (S1) of a small DC contactor is designed as a full-wave rectifier bridge circuit, which is known per se, and has connecting points (3, 5) which are connected to mains connecting poles (1, 2), and further connecting points which are connected to connecting ends of the winding (S1). A current-limiting element (Z1), for example a zener diode, is inserted in circuitry terms in one of the bridge arms, in this case in one of the current paths between a mains connecting pole (1, 2) and a connecting point for the winding connection (4, 6), as a result of which a noise reduction and good matching to different supply voltages can be achieved. <IMAGE>

Patent DE-3636635-A1 (DE)
Inventor: HEHL KARL
IPC: G05D23/19
Filed: 1986-10-28
Abstract: The flow rates in the cooling circuits of the apparatus can be controlled with the aid of a computer by means of ceramic turning valves. The computer is connected to the central computer of a plastic injection molding machine. The valve body disks, lying under constant pressure via ceramic sealing surfaces against valve seat disks, can be turned by means of pulse-controlled electric motors. Each fitting has a valve channel between the channel section of the supply channel and the channel section of the discharge channel which is covered by a valve seat disk and which forms a valve chamber. This achieves the effect that the deviations from the set temperature in the temperature-critical zones can be substantially reduced with acceptable technical expenditure. The temperature constancy achieved may be maintained for a virtually unlimited time without appreciable maintenance work.

Patent DE-3717364-A1 (DE)
Title: Closing mechanism controlled by sound pulses for ventilation vanes
Inventor: BONIN WALTER DIPL ING
IPC: E05F15/20
Filed: 1987-05-22
Abstract: TECHNICAL PROBLEM OF THE INVENTION: To eliminate sound emissions (disturbing noises, for example vehicle noise), in that an automatic closing of the ventilation aperture takes place when sound levels which become critical are reached. SOLUTION: When the critical loudness level is reached, a listening microphone transmits the closing pulse to a relay which effects the closing by means of known commercially available mechanisms (fittings). After the noise level falls again, the same mechanism opens the aperture again. POSSIBLE USES: Rooms with a need for natural ventilation which are sensitive to disturbance, are still unprotected from the point of view of construction or can be protected only at a very high cost.

Title: Device for inductive coupling of fixed-position receiving apparatuses and mobile transmitting apparatuses of vehicles travelling in lanes (tracked vehicles)
Inventor: WILMS GERHARD DIPL ING
IPC: H04B5/02
Filed: 1987-07-22
Abstract: A double line (DE) which is arranged along the driving lane and is crossed over at predetermined intervals transmits information items from the vehicles to a fixed-position station (ZE). The vehicles have transmitting antennas (AE1, AE2) which are inductively coupled to the double line (DE). The aim of the invention is to optimise this transmitting/receiving system (transceiving system), the intention being to reduce undesirable interference emission in the far field. The vehicles are equipped with two transmitting coils (AE1, AE2) which produce antiphase magnetic fields and are arranged one behind the other at the interval (KD) at which the crossings occur. The device can be implemented particularly well in the case of railways using magnetic levitation technology, since in this case double lines (DE) are used having a short interval (KD) between the crossing points. <IMAGE>

Title: Binder for a paint with a phosphorescent dye
Inventor: BELZ HANS W
IPC: C09D5/02
Filed: 1987-09-30
Abstract: A binder is presented for a paint with a phosphorescent dye. To increase the intensity of light emitted by a phosphorescent paint which can be produced economically, a binder is proposed which contains glass beads having a diameter in the range from 10 to 40  mu m. The binder base advocated is an aqueous polyvinyl propionate dispersion with a solids content of approximately 50 per cent by weight, a viscosity of 80 dPa.s at 25@C and a density of 1.13 g/cm<3>. The solvent is water with minor proportions of ethanol and butyl glycol acetate. When the binder is used for a phosphorescent paint which contains copper-doped zinc sulphide, a pH of 8.5 is chosen. The optimum luminance effect is attained if 100 parts by weight of the binder are admixed with 30 parts by weight of copper-doped zinc sulphide having an average particle size of 38  mu m.
Patent DE-3733000-A1 (DE)
Title: Damping elements for multiway diaphragms
Inventor: FRIZ RAINER CORNELIUS
IPC: H04R7/20
Filed: 1987-09-30
Abstract: A characteristic feature of multiway diaphragms is that the points of resonance of all the diaphragm elements lie in the transmission region. Because the coupling springs only become quasi-rigid below the respective resonant frequency, and thus allow the next-outer diaphragm element to be coupled into the motion, in principle these resonances cannot be eliminated. The damping of the coupling springs themselves by material selection results in a loose coupling, manifested as a saddle-shaped frequency response distortion. This does not make the linearity deviations any less. The invention relates to a damping of these resonances by a second spring excursion and boards behind the diaphragm elements which acoustically damp their surface area. In this case, the mechanism of the coupling operation is not affected. A four-way diaphragm with such damping measures is diagrammatically represented in Fig. 3. This invention makes possible for the first time multiway diaphragms which meet the highest requirements for broadbandedness and linearity. <IMAGE>

Title: Device for relieving pressure
Inventor: KILLICK ALLAN NORRIS
IPC: B01J3/02
Filed: 1987-10-07
Abstract: The invention relates to a pressure relief device for a product fluid under high pressure. A product vessel (1) is provided with a membrane (3), and, on one side of the membrane, a product supply line (20) and a product discharge line (23) are connected to the vessel (1). Valves (21, 25) are provided for controlling the flow of the fluid in each line (20, 23). A hydraulic pump (7) is connected, on the other side of the membrane (3), to the product vessel (1) and, in operation, supplies hydraulic fluid to the vessel and withdraws hydraulic fluid from the vessel. The withdrawal of hydraulic fluid results in a phase during which product is passed to the vessel, and this phase is followed by a decompression phase for the product fluid in the vessel. The supply of hydraulic fluid results in a phase of discharge of product fluid, which is followed by a phase of renewed compression or renewed pressurisation of the product fluid in the vessel. <IMAGE>

Title: Method and device for limiting the current and/or voltage of power electronics components or devices
Inventor: NEUMANN BERND
IPC: H02H1/00
Filed: 1988-12-09
Abstract: Method for limiting current and/or voltage. In power electronics components or devices, the actual values of the current and/or of the voltage are detected and compared with adjustable target values, and corrected depending on the difference. The fact that interference also enters into the measurement value prevents accurate measurement and regulation. For this reason, the actual value signals are transmitted in DC isolated mode. For this purpose, optoelectronic couplers, for example, may be provided. Interference-free transmission is possible by virtue of prior conversion into digital signals.
