Title: Pressure control device for bursting strength tester - has differential pressure gauge and electronic circuit controlling pump and pressure balancing device
Inventor: MACHACZEK ROBERT
IPC: G01N3/12
Filed: 1978-07-28
Abstract: The device tests sections of plastic tubes using a pressure gauge. The differential pressure gauge (5) is connected to the output (2) of a pump (1) generating in the specimen (4) of a uniformly rising pressure, and to a unit (V3, 8) balancing pressure rise at the differential pressure gauge (5).

Title: Overcurrent protection circuit for DC voltage controller - has logic responding to voltage reduction across controller load at overcurrent
Inventor: GRAFEN KARLHEINZ
IPC: H02H3/087
Filed: 1978-09-25
Abstract: The overcurrent protection circuit contains components that displace the controller into a safe state when an overcurrent is detected at the load connected to the controller's output. The overcurrent is detected as a reduction in the voltage drop across the load. A logic circuit comprising three NOR-gates compares the voltage from a voltage divider across the load with a reference. The voltage divider consists of two Zener diodes and a resistor. The advantage lies in the controller being protected under all conditions with no additional loss of power.

Title: Crown tiles for covering walls or roofs - made by extruding weatherproof ceramic to make pair of continuous thin tiles joined by longitudinal webs
Inventor: EICHHORN ROLF
IPC: B28B3/20
Filed: 1978-11-27
Abstract: The starting material is a ceramic which is completely resistant to frost and other climatic conditions; and the plastic ceramic mass is extruded out of a die by the known method employed in mfg. split tiles to obtain a double continuous extrudate where two tiles are joined back to back by longitudinal webs. The thickness of the tiles is reduced by increasing the size of the webs. A continuous flange is extruded along one edge of both continuous tiles, and part of the flange is removed to leave a lug on each tile. The extrudate is cut to length, dried and baked. The flanges can be on the same or opposite ends of the two continuous tiles. The wt. of the tiles can be reduced but they are still strong enough so they can be walked on when used on roofs; and the amt. of energy needed in baking the tile is thus reduced.

Title: Integrated circuit MOSFET current mirror amplifier - has two transistors with drain extensions of lower impurity concn. than drains and sited in drain-source channel
Inventor: SCHADE JUN OTTO HEINRICH
IPC: H03F3/347
Filed: 1979-01-09
Abstract: The current mirror amplifier has a graded diffusion impurity concentration in its first semiconductor zone (15, 58) in which two MOSFETs are formed with a max. concentration at the surface.

Title: Porcelain plate with second lower foot - for firing support, permitting glazing of first foot
Inventor: KAUFHOLD DETLEF-RUEDIGER DIPL
IPC: A47G19/02
Filed: 1979-03-12
Abstract: Stacked porcelain plates and saucers in canteen operations and specially on board ship cause rapid damage to the glazed surface by the annular feed which are left unglazed in the firing operations and produce scratch marks. This can be prevented if such plates and saucers are equipped with a second annular foot, concentric to the first but less high. During the firing operation the pottery rests on these second feed so that the contacting feet will be fully glazed.

Title: Air cooled laboratory cooler - with siphon closure trap and extractable condensing tube bank
Inventor: ABOUSTEIT OSMAN DR
IPC: B01L7/00
Filed: 1979-08-21
Abstract: Cooler for use in distn. and reflux boiling operations in laboratories is air cooled. Condensing tubes are enclosed in a cowl, and fans blow large quantities of air through the cowl. Tubes are joined to each other at the bottom in siphon fashion so that only liq. and not gas can escape. Upper joints between the tubes are detachable to facilitate cleaning or the entire tube bank can be extracted for cleaning. This saves the water consumption and the extra load on the drainage system, compared with water cooling.

Title: Battery-powered, three-stage propeller for sailing boat - has curved blades and is reversed when used as charging turbine
Inventor: WERNICK KLAUS DIPL ING
IPC: B63H20/00
Filed: 1979-10-26
Abstract: A sailing boat has a propeller system, driven via a reduction gear by a battery powered electric motor. Three three-bladed propellers are arranged in tandem on one horizontal shaft, spaced axially by about 1/3 of their dia. The blades are curved, with a concave and a convex side. The propeller is used either to propel the boat, or as a turbine to charge the battery. The whole motor, gear and propeller assembly can be turned about a vertical axis, so that the concave side of the blades faces aft when propelling, or forward when charging. This improves the efficiency of the propeller. The motor runs in the opposite direction when acting as a charging generator, therefore the battery polarity is reversed by a change-over switch. Current flows through the motor/generator in the same direction in either mode. A series diode prevents battery discharge at low speeds in the charging mode.

Title: Semiconductor device with high-ohmic layer - which is between low-ohmic layer and FETs to give power supply needing no conducting paths
Inventor: KRAUSE GERHARD
IPC: H01L25/065
Filed: 1980-01-11
Abstract: The semiconductor device has a semiconductor element with a drain, source and gate together with a semi-isolating GaAs substrate. A low-ohmic layer (7) is connected to the supply voltage and separate from the semiconductor element (2-4) by a high-ohmic layer (5). Further low-ohmic and high-ohmic layers may be provided. The layers form a power supply for the semiconductor element that has no conducting paths (or at least very few). The low- ohmic layer may be metal or strongly doped and may have holes through which signal lines pass. The current path between low-ohmic layer (7) and drain (2) is very high-ohmic and therefore acts as a current source.
