Title: Electro-hydraulically pilot-operated restricting valve
Inventor: POST KARL-HEINZ DR ING DR
IPC: F16K31/40
Filed: 1982-09-22
Abstract: The hydraulically actuated restricting piston of an electro-hydraulically pilot-operated restricting valve constructed as a seat valve has an operating piston and a servo piston which interacts with the operating piston and forms with a discharge passage in the restricting piston an edge control means. The operating cylinder of the operating piston is hydraulically connected on both sides via control passages to a pilot valve with a hydraulic bridge circuit, and the operating piston is mechanically connected to a position measurement transducer. The output signal from the position measurement transducer is delivered to the pilot valve for correcting its command variable.

Title: Rotary focal plane shutter for photographic cameras
Inventor: PURREITER KLAUS
IPC: G03B9/16
Filed: 1983-05-03
Abstract: The focal plane shutter is formed by two permanently rotating discs each having a slit-shaped opening. The speeds are in a fixed ratio, so that an exposure can be performed after in each case a specific number of revolutions. The common motor for the shutter discs is driven by a four-quadrant output stage of adjustable speed. A sector disc covers the film gate and releases it after actuation of the releaser for a cycle of the shutter discs. Characteristic signals of light barriers at the shutter discs and the sector disc control acceleration and retardation of the motor of the sector disc as a function of the position of the shutter discs relative to the film gate.

Title: Thrust-deflection control of aerodynamically flying aircraft and missiles
Inventor: HANNIG NORBERT
IPC: B64C15/02
Filed: 1983-06-21
Abstract: In order to reduce the drag losses in manned aircraft and unmanned missiles by means of the previous structures for elevation and lateral control and the ailerons, in reaction-driven systems, the gas jet which emerges to the rear in a straight line is deflected by means of three pairs of parallel flaps, which are mounted at the end of the gas outlet tube, such that the desired flying attitude in space is maintained or varied by the reaction produced. In this case, the three control-surface influences can be replaced individually in combination with two previous control surfaces, two of them can be replaced with one previous control surface, or all three can be replaced simultaneously. The reverse thrust during braking of the forward movement after landing is maintained. <IMAGE>

Patent DE-3332923-A1 (DE)
Title: Method and device for feeding internal-combustion engines with liquid gas (propane/butane)
Inventor: UTILI CLODOVEO
IPC: F02B43/00
Filed: 1983-09-13
Abstract: This invention describes a method and a device which is especially suitable for operating internal-combustion engines with liquid gas (propane/butane). It comprises an annular chamber around the intake port, the shape of the cross-section being of no importance for the intake port. The essential feature of this invention lies in the fact that the vaporised liquid gas is led parallel to the flow of combustion air. This is achieved in that the annular chamber has outlet apertures which guide the gas in the required direction. The advantage of this invention lies in the fact that not only carburettor engines but in particular also injection engines function perfectly according to the new method. It was found that when this device is fitted in engines which work either on the carburettor principle or on the injection principle, no conversion or modification of the engine setting of any kind is necessary. Measurements have shown that the full engine power is maintained without any increase in fuel consumption. This is confirmed by exhaust measurements which prove that an especially complete combustion of the gaseous fuel fed in takes place. This invention is especially valuable in that harmful exhaust gases are reduced to a minimum. In addition, this fuel does not require any addition of lead tetraethyl, which completely avoids this especially toxic environmental pollutant.

Title: Grains of high-purity sintered alumina, process for the preparation thereof and the use thereof
Inventor: GERK ALVIN P
IPC: C01F7/021
Filed: 1983-09-21
Abstract: A dispersion of aluminium metahydroxide is either caused to gel, or the particles are electrophoretically separated as a precipitate from the dispersion. The gel or the precipitate is dried and comminuted to give grains. The grains are, directly or after a preceding calcination, heated rapidly to a temperature above 1200 DEG C and then further heated to a sintering temperature in the range from 1200 to 1700 DEG C. The resulting grains of sintered high-purity alumina have a high density, hardness, strength, fracture toughness and a high chemical resistance and wear resistance. They can be used as abrasives or refractories. <IMAGE>

Title: Fuel injection pump for internal combustion engines
Inventor: DJORDJEVIC ILIJA DIPL ING
IPC: F02D1/02
Filed: 1983-10-11
Abstract: A fuel injection pump for internal combustion engines with a control mechanism for controlling the fuel quantity is described, in which for the purpose of compensating for the influence of the fuel temperature on the fuel injection quantity a heat-sensitive control element (18) exposed to the fuel temperature in the pump internal chamber is provided, which causes an adjustment of the fuel injection quantity via the control mechanism. In order to prevent such an adjustment of the fuel injection quantity in the idling range, the control element (18) is arranged on the retaining member (17) of an idling spring (40) in such a way that it can only act on the control mechanism once the spring travel of the idling spring (14) has been bridged. <IMAGE>
