Title: Regulation of high alternating voltages in transmission lines - has capacitor voltage divider supplying monitor via full wave rectifier
Inventor: HUGHES MICHAEL ALAN
IPC: G01R15/06
Filed: 1976-07-31
Abstract: Circuit for regulating high alternating voltages in transmission lines, contains a capacitor voltage divider (C1, C2) to form a connection across the voltage which has to be regulated and a monitoring unit (A) which is connected across one of the capacitors (C2) of the divider. When the voltage to be regulated is interrupted for a short period, the capacitor of the voltage divider supplying the monitoring unit will be discharged through a full-wave rectifier circuit for the short period which follows when the voltage is restored. The input to the rectifier circuit is via a coil and a resistor. The output of the rectifier circuit feeds a transistorised trigger circuit which operates a switch. The impedance of the discharge path increases slowly during the last section of the period and becomes effectively an open circuit at the end.

Title: Condition code system for universal data processors - with operation independent of instruction list list and mask to control selector to which condition bits are applied
Inventor: KATSAROS DAMIANOS DIPL ING
IPC: G06F9/22
Filed: 1976-08-10
Abstract: The condition code unit for a universal data processor consists of a store (M1) containing masks and base addresses, addressed by the operating code of the machine instruction list (OPC). The mask controls a selector (SHN) to which the condition bits are applied and stored. Only bits selected by the mask appear in correctly assembled order at the output of the selector to form an 8-bit distance address (DADR). The distance address is combined with the base address (BADR) in an OR-gate constructed as a parallel adder, to form a second physical address (ADR2) for a second store (M2). The second store contains a table of all condition code values for the actual instruction list. Both stores can be replaceable non-volatile types if changes to the instruction list are infrequent; otherwise they are of the random access type.

Title: Integrated circuit overload protection temp. sensor - uses two conducting semiconductor paths and voltage drop comparison
Inventor: SONNENBERGER PAUL DIPL ING
IPC: G01K7/01
Filed: 1976-10-02
Abstract: A temp. sensor for use in partic. in integrated semiconductor circuit overload protection works by comparison of voltage drops in two current paths (D1, D2) and (D3, D4) of semiconducting material varying differently w.r.t. the temp. of the protected part. A potentially destructive temp. rise is detected and an error signal produced which effects a loading reduction. The sensor is designed so that production tolerance variations are compensated to ensure that the trigger temp. variation is less than 10 degrees or in partic. 5 degrees centigrade. The current paths are of semiconducting material, in partic. forming diode paths, of the same type but of different temp. coefficient by application of different current levels. Both are thermally coupled to the protected part.

Title: Training and testing appts. for vaginal muscles - includes electromagnetic pressure transducer for measuring muscle tension and providing digital output
Inventor: REMIH HARRY
IPC: A61B5/03
Filed: 1976-10-09
Abstract: The apparatus is for the controlled exercising of the vaginal muscles. This mechanical pressure indicating gauge of the main patent is replaced by an electronic digital meter.

The comparator (34) is in turn connected to a counter (35) and a digital display unit (36). This provides an output indicating the displacement of the plunger which is dependent on the pressure in the chamber.

Title: Vehicle engine radiator thermostat valve - uses changing water pressure for switching, to lower night temp.
Inventor: RICHTER BERTA
IPC: F16K31/68
Filed: 1977-03-02
Abstract: The automatic thermostat valve for a water cooled vehicle engine is fastened to the radiator at the inlet or outlet, for an automatic lowering of temps. during the night. The changing water pressure in the heating system is used to switch the valve. The necessary water pressure changes are produced by throttling the water return in the heating system, with the circulation pump working in a different part of its range. Alternately, pressure pumps may block the water return. The changed pressure may be maintained during the day or night, so that blocking elements in the valve are not necessary. The alve has a piston, membrane, etc. so that the changed pressure can act onto the thermo-element.

Abstract: The flue gas channel used especially in boilers for firing solid, liquid or gaseous fuels, has a cross section which varies from end to end. This channel is arranged downstream of the combustion chamber which is enclosed by the water chamber. The flue gas channel, acting as a convection surface, ensures high heat transfer rate. The contraction angle (alpha) before the narrowest cross section, and the angle of divergence (beta) of cross section which form the channel walls with the channel longitudinal axis are not equal. The cross section converges with nonuniform spacing. The contraction angles can be greater than the diverging part angles.

Title: All purpose stand with several arm holders - has connectors allowing height and width of stand to be selected
Inventor: WIESMANN HERBERT LUDWIG
IPC: F21V21/06
Filed: 1977-05-20
Abstract: The oblong arms which make up the stand have matching slot in or socket sections at their ends to engage with the corresponding socket or slot in sections on the top and bottom of block or disc like connector members (4). The connectors have several dovetail grooves (9) divided around the perimeter so that the parts can be firmly clamped together.

Title: Improving germination of seeds - by swelling in gibberellic acid soln. then drying to controlled moisture content
Inventor: JELITTO KLAUS R
IPC: A01N45/00
Filed: 1977-08-12
Abstract: The germination ability of seeds normally difficult to germinate, esp. the so-called 'cold seeds', is improved by first swelling them in a soln. of 0.1-0.5% gibberellic acid (I) at about 24 degrees C. They are then quickly but carefully dried to a residual moisture content of 8% or more and stored with maintenance of this moisture content until sown. Before treatment with (I) the seeds may be cleaned with pure alcohol and esp. hard seeds can be soaked in conc. H2SO4 for about 15 min. The treatment with (I) soln. is esp. for 20-80 hr. and drying is with gently circulating air at 26-28 degrees C. A relatively quick treatment with all operations carried out at normal room or greenhouse temp.

Title: Control system for axial flow air compressor - feeds signal from anti-surge control to main control to improve stability
Inventor: EWE KURT ING GRAD
IPC: F04D27/02
Filed: 1977-08-31
Abstract: The compressor (1) delivers air to a network system (2). The flow (4) is measured and compared with a desired value (5) and the error (Xd1) fed to a controller (R1) which varies the compressor speed. The discharge pressure (10) and intake volume (12) generate a second error signal (Xd2) which controls a blow off valve (8) to prevent surging at low throughputs. The second error signal (Xd2) is fed through two non-linear amplifiers (13, 16) into the first control circuit (R1). This modifies changes in speed to prevent surging as a result of over rapid changes. The output of one amplifier (13) modifies the error signal and the output of the second (16) reduces it.
