Title: Solder beads inductive heating system - uses eddy-current coating-thickness measuring instrument
Inventor: SELIG OTMAR DIPL ING DR
IPC: B23K1/002
Filed: 1979-01-03
Abstract: The induction heating system, for e.g. solder beads on printed circuit boards, uses an eddy-current coating-thickness measuring instrument and adjusts e.g. the solder energy in accordance with the real component of the impedance. The coupling distance is varied based on a previous measurement under the same heating conditions. A measuring coil can be used to check the inductively heated parts. The measuring coil is adapted to the heating coil and used to optimise the heating coil.

Title: Ensuring rhythmic flow of gas in ceramic kiln - by reciprocating gas-holder bell in branch off-gas duct
Inventor: HAESSLER ANDREAS ING GRAD
IPC: C04B33/32
Filed: 1979-01-24
Abstract: Tunnel kilns or other continuously operated kilns used for firing of ceramic articles are pref. operated with a rhythmical gas flow in and out of the kiln space. The gas flow is produced by arranging in a branch duct, off the flue leading to the chimney, a gas displacement appts. such as the reciprocating bell of a gasholder, with shutters on either side of the branch. This saves the electric power for the gas pumps and can be used to discharge a certain part at each working stroke into the chimney.

Title: Dewatering starch concentrate from potatoes - by first carrying out enzyme conversion of some starch to sugar followed by solvent extraction with polar solvent and pressure filtration
Inventor: GIESEMANN HANS-GEORG
IPC: C08B30/10
Filed: 1979-03-08
Abstract: During starch prodn. from potato pulp, the initial pulp has a wt. content of 10% solids. This is subjected to an enzyme reaction at 60-100 degrees C to convert some starch to glucose. The resulting slurry is subjected to pressure filtration. The moist cake from this, contg. 25% solids is then mixed with water or a polar solvent such as CH OH ethanol, isopropanol etc. The resulting slurry is then further filtered in a pressure filtrate to give a cake of 40 - 45 wt.% of solids, which is then dried. Used for producing starch from potatoes. Reduces the energy consumption per unit of starch.
Patent DE-2912700-A1 (DE)
Title: Insulated-gate FET for PROM in telephone exchange - has source overlapping storage gate to allow small substrate-drain voltages
Inventor: MUELLER RUDOLF DIPL PHYS DR
IPC: H01L29/788
Filed: 1979-03-30
Abstract: The IGFET has a storage gate insulated on all sides and charged by shortwave electromagnetic radiation. A reverse biasing voltage is applied to the pn-junction between drain and/or source on the one hand and the substrate on the other. This voltage is large but not sufficient to cause avalanche breakdown. The source (S) and/or the drain (D) on the one hand overlap the storage gate (G1) on the other. A control gate (G2) controls the charging of the storage gate to a potential differing from that of the substrate (Su). The advantage lies in increasing the speed with which the gate is charged. The structure is esp. suitable for IGFETs with short channels only capable of handling very small substrate/drain voltages and for which charging the storage gate by employing substrate/drain avalanche is made difficult due to the shortness of the channel and associated punch-through.

Title: Resectoscope for treatment of urethral and bladder lesions - contains endoscope coaxially sheathed by outer shaft sleeve, with annular space in between for anti-friction agent
IPC: A61B1/12
Filed: 1979-04-14
Abstract: The resectoscope consists of an optical endoscope and a surgical instrument next to the latter. The two components are enclosed in a common endoscope tube. An additional outer tube (21) is arranged coaxially to the endoscope tube (22), an annular free space (25) being left between these tubes. This space is connected to a terminal (23) for a pressure line supplying an anti-friction agent. Pref. the outer tube has apertures (24) for the passage of this agent, which may be formed as mutually offset longitudinal holes. A strengthening (27) of the outer tube may be provided and may contain a bayonet union for securing of the outer tube on the head (9) of the resectoscope. The end (26) of the outer tube may be folded inside over the endoscope tube (22). The design enables a supply of an anti-friction agent without the need to interrupt the surgical treatment.

Title: Switch over pipe connection - has tube fixed to tubular connector slidable from one to other pipe and axially movable to make seal to pipe
Inventor: LINDER HERMANN J
IPC: B65G53/56
Filed: 1979-07-10

The connector carries a pin (12) extending into a slot (11) of a slide block. The slot has a lateral recess (17) which allows axial movement of the pin when the block is moved across to disengage the pipe connection. The connector itself is held by a wheeled (15) carriage (2) running on rails (10,13), which allows the connector to be moved across between stops from alignment with one pipe to the other.
Patent DE-2929351-A1 (DE)
Title: O=ring seal for rotating shaft - is located in seal ring groove pressurised to force seal element against shaft
Inventor: SCHMIDT ALFRED
IPC: F16J15/32
Filed: 1979-07-20
Abstract: A rotary shaft seal assembly includes an O-ring (7) which is located in a radial groove (4) on the shaft bearing collar (2). The axial width of the seal ring location groove (4) is slightly less than the O-ring thickness. The base of the seal ring location groove (4) is linked to the pressure side (5) by a small axial hole (8) in the shaft collar (2). Thus the O-ring is forced outwards against the bearing sleeve (1) by the applied pressure, therefore increasing its sealing capacity.

Title: High-pressure pump valve assembly - has closure member sliding on cylinder with clearance acting as throttle when closed valve is pressurised
Inventor: NENDZIG GERHARD DIPL ING
IPC: F04B53/10
Filed: 1980-02-02
Abstract: The valve assembly is particularly intended for a high-pressure pump with a piston (2). It comprises an annular seat (13a,b) for a bush-shaped closure member (15a,b) controlling the flow passage (21a,b). The member is slidable on a cylindrical surface (16a,b) and has its seating surface (19a,b) radially outward of the surface (16a,b). The narrow annular gap (18a,b) between the closure member and the surface (16a,b) acts as throttle between high and low pressure when the valve is in the closed position. Without high-pressure load on the closure member, the gap (18a,b) width pref. is a fraction of one mm, e.g. between 0.005 and 0.02 mm, which width may be reduced by the member being subjected to this pressure.

Title: HV gas blast circuit breaker - has arc extinction paths formed by curved ends of radial segments of moving contact
Inventor: BONIN ECKHARDT VON
IPC: H01H33/70
Filed: 1980-02-16
Abstract: The gas blast high voltage circuit breaker with a moving contact inserted into a cylinder with double walls between which is supported a fixed piston, has the top of the cylinder formed by a ring of radial segments (4). The gas is forced through the narrow gaps between the segments against the end of the moving contact as it enters into the engaged position. The tops of the segments are curved, forming a return bend, so that arcs (1) struck on the tops (3) of the curved parts tend to travel inwards around the curved surfaces. The length of the segments forms an arc extinction path and the distance (X) inside the bent over ends is greater than the inside diameter (2) between their tips. The operative length of the path is about one and a half times the inside diameter.

Title: Heating coil supports for underfloor heating - are deep drawn plastics strips with grooves retaining pipes below top surface
Inventor: FEIST ARTUS
IPC: F24D3/14
Filed: 1980-06-27
Abstract: The underfloor heating system using a heating coil, uses plastics strips to support the pipes (24) forming the coil. Each strip has parallel grooves (28) across it, into which a pipe can be embedded. The material (42) from which the strip is made is of a thickness to enable it to be deep drawn, leaving hollow chambers (26) between the grooves.
