Title: Priming compsn. for insulating e.g. metal surfaces, - contains mixt. of polychloroprene soln., acrylonitrile! and butadiene! copolymer soln. and opt. filler
Inventor: RADOMIL MILAN
IPC: C08L9/02
Filed: 1978-02-13
Abstract: Priming compsn. consists of a rubber elastomer mixt. comprising, by wt., (1) 5-99.8 pts soln. of 0.1-60 pts polychlorophene in 40-99.9 pts organic solvent(s), (2) 0.2-95 pts soln. of 1-70 pts butadiene-acrylonitrile copolymer rubber contg. 1-90 pts acrylonitrile, in 30-99 pts organic solvent(s), and opt. (3) 0.01-50 pts filler(s). The use of compsns. for insulating surfaces, e.g. metal, is claimed. The compsns. economically replace bituminous, plastics- or spoxy resin-based primers. They can also be used for repairing and insulating pipe welds and connections, and for protecting concrete, stone and wood surfaces against water penetration and weathering. The compsns. combine wide, universal use with improved adhesion. In laminated plastics, adhesion to a steel surface is 10-100% higher than when using a standard primer, e.g. "Alkaprene" (RTM).

Title: Room air ventilation system - has cross=section of larger portion of duct altered dependent on environmental conditions
Inventor: FISCHBACH KARL HEINZ
IPC: F24F13/24
Filed: 1978-03-08
Abstract: The room ventilation system has a duct with an opening at each end and running at right angles to the openings. The air current passes through a larger cross-section at one opening that at the other, so that in the duct immediately before or after the larger opening it passes spontaneously through a portion with even larger cross-section. The volume of the larger portion (5) is altered dependent on pressure and/or flow proportions or other varying environmental conditions, e.g. temp. gas concentrations at various measurement points (32L4) along the path of the air current (3, 5, 6', 6").

Title: Timing chain tensioner for IC engine - has plastics insert in pulley to compensate differential thermal expansion between chain and chain centres
Inventor: RUEGER HANS ING GRAD
IPC: F16H7/12
Filed: 1978-05-03
Abstract: The engine has a chain drive from the crankshaft to the camshaft. The chain runs over a tensioning sprocket (10) which is mounted on a bracket on the engine block to be adjustable to adjust the tension. The sprocket (10) has an outer toothed ring (12, 13) for the chain. The outer ring runs on a bearing (15) on the central hub (11) which is bolted to the bracket. A layer of rubber or plastic (16) is inserted between the bearing and the outer ring. This takes up differences in thermal expansion between the chain and the engine to avoid increases in the set tension.

Title: Resistance heater with two resistance elements - which are for different supply voltages in channels in core separated by earthed metal plate
Inventor: LIED JOCHEN
IPC: H05B3/40
Filed: 1979-01-26
Abstract: The heating element can be supplied from various voltage sources, (low voltage or mains supply) and is simple and cheap to fabricate. Two resistance heating elements (3a, 3b) are located in separate channels (2) in a cylindrical core (1) and are for connecting to two different voltage supplies. The resistances of the elements are chosen according to the supply voltages and temperatures desired. An earthed metal plate (7) fits into a cavity in the core and separates the two heating elements. Alternatively, instead of the core being a solid cylinder (or a prismatic shape) it may consist of two half cylinders (or prisms) one each side of the earthed metal plate. The core is enclosed in a suitable sheath.

Title: Measurement of quantity of fish in drag net - uses sweep generator and absorption resonance analyser for net sensors
Inventor: HOERING FRITZ DR
IPC: A01K73/10
Filed: 1979-05-17
Abstract: The device for measuring the catch in a dragnet uses several level sensors connected to an evaluation circuit and arranged at intervals along the dragnet. Reliable level monitoring is ensured by simplification of installation and maintenance of the sensors compared to conventional arrangements. Each level sensor has an absorption resonance circuit tuned to the characteristic frequency of the sensor which varies when the net is fitted to its height. All the sensors are supplied from a common cable connected to a sweep generator whose frequency variation encompasses the frequencies of all sensors. The evaluation circuit contains a device which counts the number of the frequency dependent signal level disruptions per sweep period. The sweep frequency and output signal transfers are controlled by a common clock generator.

Inventor: LEITGEB WALTER DIPL ING
IPC: G01F23/04
Filed: 1979-06-09
Abstract: A measuring device for determining the oil level in a closed housing, especially of internal combustion engines and transmissions. The device is provided with a sleeve fixed to the housing, and a removable measuring rod or dipstick.

Title: Magnetically driven travelling electric arc for welding metal parts - by traversing parts to heat metal to welding temp.
Inventor: RUDD WALLACE C
IPC: B23K9/08
Filed: 1979-12-21
Abstract: Metal parts are welded and heat treated using an electric arc formed between a pair of adjacent parts or between an electrode and a metal part. The arc is traversed over the metal part(s) using a magnetic field. The arc can be initiated, driven by the magnetic field across the parts, extinguished and then reinitiated. Alternatively, the arc can traverse the surfaces of the parts in alternately opposite directions. Uniform heating can be effected to surfaces which are larger than the cross-section of the impinging arc. Discontinuous surfaces can be heated with repeated passes of the arc. The arc may be d.c. or a.c. and the magnetic field may be constant or variable in both magnitude and polarity.

Title: Filter for removing dust from hot gases - has layer of material resistant to temp. exceeding 800 degrees C., esp. for treating gas from metallurgical reactors, coal gasifiers etc.
Inventor: PFEIFFER ROLAND DIPL PHYS DR
IPC: B01D39/06
Filed: 1980-01-29
Abstract: Gases charged with hot granular solids are cleaned by a layer of material resistant to temps. above 800 deg ... The material may be a fired or graphitised organic material, or a refractory fibre of mineral wool, slag wool etc. compacted into a felt or as a loose filling. If in felt form the material may be shaped into a bag. The refractory material may be in a perforated box-like housing put into the conduit carrying the dusty air, and in such case the housing may extend laterally on both sides of the conduit, with open ends so that filter material can be pushed into it and discharged from the other end when fully laden with dust. Used for exhaust gases from metallurgical reactors, coal gasifiers etc. No heat exchangers are needed,nor need cooler air be added, which would increase the filtration plant size .

Title: Internal temp. control of spacecraft - uses sealed liq. panel that changes thickness to control heat loss and maintain constant internal temp.
Inventor: PIENING HELMUT HANS DIPL ING
IPC: G05D23/01
Filed: 1980-05-06
Abstract: A variable thickness panel is built into the side of a spacecraft e.g. an information satellite to maintain a constant internal temperature. The heat loss through the walls of the craft is dependent upon internal heat generation and the external conditions in space. The rate of heat dissipation through the walls is controlled by a fluid film (9) located between two panels (7,8). The panels are produced as a sealed unit with bellows element (12,13) side walls that can expand or contract to vary the internal gap. Bimetallic strips (10,11) are built into the unit and respond to temperature to control the gap. If the temperature is too high the gap reduces and if the temperature is too low the gap increases.

Title: Fruit machine with electronic circuit - identifying win conditions and controlling bonus play cycles
Inventor: GAUSELMANN PAUL
IPC: G07F17/34
Filed: 1980-05-07
Abstract: The fruit machine has an electronic control unit to control the operation of the three rotating symbol drums and to determine the bonus win modes. The rotation of the three drums is controlled by signals generated by a central control with gating stages coupled to the first two stages. A contact array is switched to indicate the winning combination and specific outputs activated. A win counter unit has two stages; one for normal play cycles and another for bonus cycles. Specific output combinations are identified by gating logic coupled to flip flops that control the drive signals for the drums.
