Title: Sepn. of tensides from solvent and oil extracts
Inventor: BOLLING ENNO
IPC: B01D15/00
Filed: 1993-02-02
Abstract: For the automatic separation of polar components, especially tensides from solvents and hydrocarbons and especially oil extracts, the hydrocarbon extract and especially oil extract is displaced by polar adsorption and the mixture is stirred to bond the polar components to adsorbents. The extract free of polar components is separated from the polar adsorbents, for detection analysis of the hydrocarbon and especially oil concentration in the extract. Also claimed is an appts. with an extraction vessel (2) with at least one adsorbent feed (9) from a supply (5) and at least one solvent and oil extract feed (1) and an outlet (10) for tenside-free extract and an adsorbent outlet (18) from the sediment zone (4) of the vessel (2).Aluminium oxide is used as the polar adsorbent, to be stirred with the mixture of solvent and hydrocarbon and especially oil extract. The extract free of polar components is separated from the adsorbents by precipitation, followed by filtering out residual water before the extract is passed to a detection unit for analysis. After analysis, the extract is transferred to a regeneration plant, and the adsorbents are caught for the solvent to drop free for regeneration.The tenside-free solvent and solvent released from the adsorbents are regenerated for use with the actual infra-red absorption measurement, with detection analysis to register the light absorption of the amount of delivered infra-red light. An automatic rinsing with clean solvent follows each sampling.

Title: Swing-out sliding door for vehicles, in particular vehicles of public passenger transportation
Inventor: HORN MANFRED
IPC: E05F15/60
Filed: 1993-05-11
Abstract: A swing-out sliding door for vehicles, in particular vehicles of public passenger transportation. Arranged on the inside of the door wing (2), essentially in the region of the horizontal centre, is a running rail (4) which runs horizontally and in which a roller guide (5) engages. The roller guide (5) is mounted in an intermediate holder (6.2) which is mounted, such that it can be displaced in the vertical direction, on a holder (6) connected fixedly to the vehicle body. During the opening movement of the door the door wing (2) is initially guided outwards and upwards, in a first movement step (Ö1), in order subsequently to be displaced laterally on the roller guide (5) in a second movement step. The door wing (2), which is of elastic design, is pretensioned in such a manner that, when the side edges of the door wing are placed onto the mating faces of the door frame (1), as a consequence of the pretensioning force a contact pressure results which ensures that the door is closed all the way around. <IMAGE>

Title: Transmission and/or reception system with optimised polarisation conversion
Inventor: MUELLER WOLFGANG DIPL ING
IPC: H01Q13/02
Filed: 1993-07-09
Abstract: A transmission and/or reception system for transmitting and receiving satellite signals, comprising a feed 1 and at least one converter 3, 4, is optimised in terms of selectivity and decoupling characteristics. For this purpose, in order to suppress the reflection of the incoming wave, an isolator 5, 6 is placed in front of the converter 3 to reduce cross-polarisations caused by these reflections. Furthermore, grooves which alter the polarisation characteristics of the waveguide or make it an independent polarisation converter can be fitted in the feed 1 or in a downstream waveguide 13. Grooves of this type, which are preferably disposed in a longitudinal direction, can also improve or alter the polarisation characteristics of an existing polarisation converter. In addition, the mid-frequency of an existing polarisation converter present in the transmission and reception system can be shifted by inserting a dielectric and/or metallic material, preferably a self-adhesive aluminium foil, into the radiation field of the feed to enable adaptation of the transmission and reception system to a different frequency without major reconstruction. <IMAGE>

Patent DE-4330065-A1 (DE)
Title: Bolometer
Inventor: TINCHEV SAVTCHO
IPC: G01J5/24
Filed: 1993-09-06
Abstract: In the case of known bolometers, the principle of the bridge circuit is used. Connected electrically into at least one bridge arm are measurement pick-ups or pick-up converters. The electrical equilibrium of the bridge is disturbed on heating up the measurement pick-up and the current caused thereby yields the measured value. In these arrangements, making electrical contact is disadvantageous. It has a thermally dissipating effect and impairs the temperature sensitivity and the dynamic behaviour. In the case of the application of measuring sensors made of superconductive thin films - with which a high resolution capability is achieved - the production of the coil structure from the superconductor and the electrical connection present difficulties, and the exact maintenance of the operating temperature of the measuring sensor is also associated with an increased expenditure during the use of common high-temperature superconductors. In the case of the bolometer according to the invention, the measuring sensor is no longer bound electrically into the circuit construction. It is designed as a closed-area epitaxial thin film of an HTc superconductor whose transition temperature has been reduced to the temperature of liquid nitrogen by implantation of oxygen ions.   To convert the measured variable E into an electrical variable, a parallel resonant circuit 2 is used, having a flat coil 21, via which eddy currents are generated in the measuring sensor. Connected to the resonant circuit 2 is a voltage-controlled oscillator 3, which feeds the resonant circuit... Original abstract incomplete. <IMAGE>

Title: Controller for switching the electric drive motor, in particular of an air compressor, on and off to match the demand
Inventor: BRUNS HARTMUT
IPC: H02H6/00
Filed: 1993-10-01
Abstract: In the case of a controller for switching the electric drive motor, in particular of an air compressor, on and off to match the demand, the thermal load on which air compressor is determined in accordance with a load characteristic from the ratio of the switched-on time to the sum of the switched-on and the switched-off time, difference values are added in order to determine the total switched-on time which is relevant for the thermal load, said difference values being formed from the individual switched-on times minus the equivalent switched-on times which correspond to the respectively subsequent switched-off times according to the load characteristic. When the relevant total switched-on time exceeds a predetermined limit value, the drive motor is turned off for a time which can be predetermined, in order to provide protection against overloading and possible destruction.

Title: Thermal energy production process using solar neutrinos - achieved by their capture and subsequent annihilation with antineutrinos produced by the beta decay of neutrons.
Inventor: LINDEMANN HANS DIPL ING
IPC: F24J2/00
Filed: 1993-12-08
Abstract: A means for driving a solar power plant by using the energy of neutrinos produced by the nuclear fusion reaction taking place within the sun. The energy is used to heat a thermal power plant and hence for the direct production of electricity. A dual neutrino catcher and protection surface is so controlled and driven that an axis perpendicular to its surface points constantly at the sun independent of the sun's position relative to the earth and regardless of whether it is cloudy, night-time or day-time. In order to achieve this the catcher surface is fully rotatable through 360 degrees about three orthogonal axes. The beta decay of neutrons is used to produce anti-neutrinos and these are collided with the neutrinos of solar origin. The resulting annihilation produces the heat to drive the thermal power plant. The production of neutrons for the beta decay to produce a proton, electron and an anti-neutrino is energy intensive, however the neutrino anti-neutrino reaction produces much more energy than is consumed. Precautions must be taken to ensure that the production of neutrons cannot lead to a chain reaction situation. USE/ADVANTAGE - Process produces electricity from the energy of solar neutrinos. In comparison with other photon-driven solar power plants, the new unit has the major advantage that it has a constant power capacity regardless of weather conditions or time of day.
