Title: Push-pull DC voltage converter for power switchgear - has current feed via semiconductor switch in front of choke coil, simultaneously controlling part of switchgear
Inventor: SCHOLZ HORST ING GRAD
IPC: H02M3/337
Filed: 1980-12-24
Abstract: The direct voltage converter consists of a bridge push-pull assembly with semiconductors and has a current feed via a choke coil. This current feed of the push-pull converter (1) takes place via a semiconductor switch, incorporated in front of the choke coil (1). This switch forms simultaneously a switching control for the mains switchgear with optimum energisation. This control regulates, at a variable time period (tv) after the ONE instant, the conductor state by two corresponding (10,13;11,12) of the bridge push-pull converter. It remains non-conductive at a fixed time period (tu) before the OFF instant. A relay circuit (32) is connected to the semiconductor switch (32). The choke coil has a second winding, coupled to the rectifier output (53) of the direct voltage converter, via a decoupling diode (22).

Title: Cell for detecting phosphoric acid ester(s) in atmos. - has silver chloride coated silicone rubber layer on electrolyte surface
Inventor: KRONEISEN ARMIN DIPL CHEM DR
IPC: G01N33/00
Filed: 1980-12-24
Abstract: The presence of toxic phosphoric acid esters in the atmos. is detected by a cell divided by a vertical diaphragm into two compartments contg. an immobilised alkaline electrolyte whose surface in each compartment is covered by a sieve-like Ag electrode. An oxime is fed into one compartment and the current flowing in a circuit closing the electrodes is proportional to the toxic component concn. A layer of silicone rubber covered with silver fluoride is laid on the electrolyte surface adjacent the electrode. The electrode support may be an ion-exchange membrane. A third Ag electrode may be used, connected to a movable contact on a potentiometer joining the other electrodes, in which case the coated silicone rubber layer may be omitted. The silver fluoride converts V agents into G agents, and is also more effective than the cell in the parent patent for binding those additional gases which could produce interference signals at the electrodes. The third electrode system is used when only G agents are involved.

Title: Use of a drying process for the removal of petroleum spirit from meal and extraction system for carrying out the process
Inventor: WEBER KLAUS DIPL ING
IPC: C11B1/10
Filed: 1981-05-02
Abstract: A process known from drying techniques is used to remove petroleum spirit from the meal produced in the extraction of oil seeds and is adapted to the operation of an extraction system. In this process, heated beads are mixed in large quantities with the meal, which is moist with solvent, on its way from the extractor to the toaster, are separated again from the meal after delivering heat to it, are heated again and, in a continuous circulation, are again mixed with moist meal. The petroleum spirit is completely, or at any rate mostly, removed from the meal in this way by contact heat before it enters the toaster. It is possible in this way to dispense at least substantially with the steam treatment in the toaster which has hitherto been necessary to remove petroleum spirit. Wetting of the meal by condensed steam is avoided and, accordingly, the energy expended on the final drying is reduced.

Title: Cushioning for leg prostheses
Inventor: BIEBER HANS-GUENTER
IPC: A61F2/60
Filed: 1981-07-04
Abstract: The innovation relates to use of magnets which oppose each other with the same poles (n) and result in a cushioning effect due to magnetic fields (f). According to the drawing, the magnets are attached so as to be rotatable downwards during application (a), so that a cushioning is produced by the magnetic fields during loading. By rolling the foot from heel to toe the angle formed by the magnets is reduced. The magnetic field has a damping effect on the rolling process. Vertically inserted magnets (b) produce the same cushioning effect by corresponding guides. The magnets can be replaced by cushioning elements such as helical springs or air/gas pads held in devices. The leg prostheses of previous designs transmit the compressive effect occurring on placing the foot on to the ground to a considerable part of the human skeleton, and this may result in damage due to continual loading. The cushioning is intended to relieve the loaded parts of the skeleton. <IMAGE>

Title: Eddy-current test device for detecting surface defects
Inventor: CHRISTMANN BURKHARD DR
IPC: G01N27/90
Filed: 1981-09-29
Abstract: In an eddy-current test device consisting of a combination of two types of high-frequency sensing coil systems for selectively detecting cracks or other material defects in the surface of electrically conducting objects moving relatively to the test device, in which an eddy-current field is excited in the object by means of a coil system of the first or second type and changes in the eddy-current field due to material defects are detected by a coil system of the other type in each case as a result of evaluating the induced voltages, the object is to facilitate good separation between different surface defects such as cracks and slits. The test device should also be capable of operating at elevated temperatures (over 1,000 DEG C). The object is achieved by constructing a sensing coil system of the first type in such a way that during excitation in an object (1), an eddy-current field (2) is produced which is geometrically similar to that of a U-shaped core coil system operated with alternating current with its limbs (3) directed towards the surface of the object and that the sensing coil system of the second type (4) is arranged in the symmetry plane of the sensing coil system of the first type and is itself symmetrical with respect to said plane. The invention is applied in the production of semi-finished products, for example for examining material before rolling processes. <IMAGE>

Title: Method for positioning a radar antenna or the like
Inventor: DURE NORBERT DIPL ING
IPC: H01Q3/06
Filed: 1981-11-30
Abstract: The invention relates to a method for positioning a radar antenna, which is driven by a three-phase asynchronous motor, or the like. After entering the positioning command, one phase of the asynchronous motor (AM) which drives the radar antenna or the like is reversed and, simultaneously or shortly thereafter, the motor which is normally connected in delta is changed over to star connection. This results in braking from the operating speed until the direction is reversed followed by running in the new direction until the desired positioning point is reached, when power is disconnected from the motor and said motor is stopped by means of a magnetic brake (MBr). Slow running to the positioning point after the direction reversal is achieved by means of a torque characteristic which drops once the motor has started. The invention can be used for controlling the drives of radar surveillance antennas. <IMAGE>

Title: Foldable crank for a hinge cord pulley
Inventor: SAKUMOTO AKINORI
IPC: G05G1/08
Filed: 1981-12-11
Abstract: What is described is a crank or a crank-folding device for a hinge cord pulley, which can eliminate looseness as a result of small gaps between a crank axle (2) and a crank (7) on the one hand and between the crank (7) and a crank detent (12) on the other hand, so that the crank (7) is connected to the crank axle (2) reliably and free of play and a uniform or jolt-free rotation of the crank (7) is thereby guaranteed. With this device, the crank (7) can be folded quickly and smoothly in one action by rotating it or swinging it down, whilst the crank detent (12) projecting above its top side is pressed in counter to the force of a spring (14). The crank (7) folded in this way can then be locked automatically against the crank axle (2) simply by rotating it back into its original (swung-out) position. <IMAGE>
