Patent DE-2516983-A1 (DE)
Title: Seamless angled curtain track with front panel - has travelling trolleys actuated from firing stand for target manipulation
Inventor: MOELLER HUBERT
IPC: A47H1/04
Filed: 1975-04-17
Abstract: For seamless angled curtain tracks a triangular section is cut out of the rail so that the connecting point for the fascia panel which is to hold the two rail sections together corresponds to a point of the triangle. Connecting pins can be then inserted into the track groove or other cavity in the rail sections and on bending the fascia panel made of e.g. foam material the two cut faces of the rail can be placed together so that the connecting pins fit into each other when the cut faces are closed up and the rail is secured in its angled shape. The final angle of the track is variable and depends on the shape of the cut-out section, for example an isosceles triangle produces a track with a right-angled bend.

Title: Condensing system for atomic power station - rejects heat to district heating system to reduce cooling water requirement
Inventor: EIGNER OTTO
IPC: F01K23/02
Filed: 1975-05-28
Abstract: The condensing system for atomic power station employs a heat pump with compressed air as working fluid to condense and remove heat from the exhaust of a steam turbine power generating set in accordance with the main patent. A further steam turbine power generating set is provided and the exhaust from this is condensed in a heat exchanger where it heats the air returning to the low pressure compresser. The compressed air is cooled in a heat exchanger in which it raises the temp. of water returning from a district heating network. Between this heat exchanger and the expansion turbine the compressed air is further cooled by the low pressure discharge from the expansion turbine in an air to air heat exchanger.

Title: Tyre wear indicator - has electrical conductor embedded in tread at minimum safe tread thickness level
Inventor: BREUER WERNER
IPC: B60C11/24
Filed: 1975-06-03
Abstract: A motor vehicle tyre incorporates a conductor to indicate the maximum permissible degree of tyre tread wear. The tyre has girdle plies on a carcase, a profiled tread with lands and channels or grooves and side walls. An electric conductor is incorporated in the tread at the minimum prescribed distance above the bottom of the tread profiles including those in the side wall. As wear proceeds the conductor wears through and the circuit is interrupted, thereby causing an audible and/or visual warning to be given. The nature of the conductor is such as to adapt it for any special tyre of tread e.g. with transverse profile grooves.

Title: Data recorder and reproducer - operates whilst tape is accelerating and decelerating to or from normal running speed
Inventor: EIBNER JULES ARTHUR
IPC: G11B20/10
Filed: 1975-06-30
Abstract: A recording/reading system uses magnetic tape as an input/output unit for a data processor in which recording/reproduction can be undertaken whilst the tape is starting up travel, without waiting for normal running speed to be reached. A tachometer is coupled to the tape drive roller which feeds pulse train representing the instantaneous tape speed to a detector which acts as a threshold detector to feed a switching-on signal to a fixed phase oscillator when the speed is above a critical minimum value. The fixed phase oscillator together with a phase comparator controls the flow of data from the source to the recording head according to the speed as represented by the pulse train from the tachometer.

Filed: 1975-07-10
Abstract: An electronic circuit in more than one form for use processing the analogue signal from a basic transducer and for monitoring the waveform of this signal to avoid false alarms is used.

Title: Flexible coupling for gyroscope drive - has solid disc machined to provide two flexible driving strips
Inventor: HABERLAND RUEDIGER DR
IPC: F16C11/12
Filed: 1976-06-15
Abstract: The flexible coupling for driving a gyroscope is machined from a solid disc. Four holes of triangular cross-section with curved sides and rounded corners are cut through the disc. A curved slot (52) extending through an arc of 200 deg. is cut in each end surface. The slots are diametrically opposite and their depth is slightly greater than half the disc thickness. A circumferential slot in the plane of the disc is then cut which runs into the curved slot so that the disc is almost separated into two similar discs being connected only by the thin wall of metal (46) and the flexible strips (26, 28). A further machining operation reduces the width of the strips and separates them with a central slot in the plane of the disc.

Title: Automatically driven heat exchanger rotor - is coupled to vaned wheel over which air is blown
Inventor: WAGNER GEB NOTTER MARGARETE
IPC: F28D19/04
Filed: 1977-03-01
Abstract: The heat eachanger rotor is automatically driven by a vaned wheel, caused to rotate by the inlet or discharge air blown over it, and coupled to the rotor. The end face of the rotor is also in the form of a vaned wheel, and air is guided through the rotor along an oblique or curved path and not a straight one. The inlet or discharge air is blown onto the rotor at an angle to its axis, either by means of a specially-shaped feed conduit or by mounting deflector vanes in the latter. No external power is thus required, and the heat exchanger is usable in quite small air-conditioning equipment.

Title: Catalyst bed for hydrocarbon cracking - having silicon carbide components to improve temp distribution
Inventor: SZABO DE BUCS EUGEN DR
IPC: B01J8/00
Filed: 1977-03-03
Abstract: Gas generator converts a stream of gas or liquid at elevated temp. It contains a bed of catalyst with distributor plate of SiC across it. These are mounted at 90 degrees to the flow of reactants or can be parallel to it. The catalyst is in the form of a particle bed. The generator consists of a cylindrical vessel with a gas distributor plate at the top. This has a series of narrow passages which give sufficient pressure drop for the gas to be adequately distributed over the area of the vessel. The plate vitually fills the cross section of the vessel. For use in the oxidated catalytic cracking of hydrocarbons to give gaseous fuels esp. for upgrading low octane fractions to high octane fuels for i.c. engines. Conventional beds suffer from C deposition due to poor temp. distribution. The SiC inserts are of relatively high conductivity and they ensure that the temp. remains uniform throughout the bed.
