Title: Power transistor protection circuit
Inventor: RATCLIFF HENRY KEVIN
IPC: H03F1/52
Filed: 1984-01-12
Abstract: A protection circuit for a power transistor (Q1) having a tuned load comprised by the parallel combination of a capacitance (C1) and an impedance (P1), the protection circuit comprising a capacitance (C2) in series with a switching means, which brings the capacitance (C2) into parallel connection with the capacitance (C1) of the tuned load to detune it in the event that the instantaneous voltage across the power transistor (Q1) exceeds a predetermined level. The switching means can comprise a silicon controlled rectifier (SCR1) whose gate is controlled via a diode (D3) and resistor (R1) in dependence upon the instantaneous voltage across the transistor (Q1). The silicon controlled rectifier (SCR1) is connected in anti- parallel relationship with a diode (D1), whereby when the silicon controlled rectifier is in its conducting state, the silicon controlled rectifier/diode- rectifier combination acts as an effective short circuit to a.c. <IMAGE>

Title: Mine to be buried for use in war
Inventor: TADDEO VITO
IPC: F42B23/24
Filed: 1984-01-19
Abstract: A mine (1) for burial in war has an explosive effect which develops in a horizontal sense. This is achieved by virtue of the fact that the mine (1) is rotatably mounted on a frame (2) and, when activated, is rotated out of the ground (T) before it explodes. The rotation of the mine (1) is caused by a powder motor (32) subject to an external control such as a trip device (37), while the explosion of the mine (1) is caused automatically by a cam (28) when it reaches a predetermined angle of rotation. <IMAGE>

Title: Flow prover
Inventor: ERICKSON CHARLES D
IPC: G01F25/00
Filed: 1984-10-26
Abstract: The flow prover for calibrating continuous flowmeters includes a measuring housing 2 comprising a main cylinder 9 having a substantially uniform inside diameter and inlet (6) and downstream (10) sections having inside diameters greater than the main cylinder 9. A displacer 7 movably disposed within the housing 2 has seals 28, 29 which form a fluid barrier while the displacer 7 is disposed within the main cylinder 9. Inlet and downstream section guide means maintain the displacer 7 in axial alignment with the main cylinder 9 while the displacer is disposed within either of these sections 6, 10, assuring smooth exit and entry. The seals 28, 29 are circumferentially compressed when the displacer 7 enters the main cylinder 9 and may be statically or dynamically monitored for integrity without an external pressure source. Means for returning the displacer 7 from the downstream section 10 to the inlet section 6 following a proving cycle and means for detecting the longitudinal disposition of the displacer 7 during a proving cycle are provided. The flow prover also includes an inlet conduit 1, an outlet conduit 11, and a valved bypass conduit 3 fluidly connecting them. The bypass valve 4 is of simple poppet construction, designed to operate at the differential pressure of the flow prover, which is considerably lower than the rated internal pressure of the flow prover. <IMAGE>

Title: Liquid-liquid extraction
Inventor: ROWDEN GEORGE ALAN
IPC: B01D11/04
Filed: 1985-02-19
Abstract: A method of effecting liquid- liquid contact between an aqueous liquid medium and an organic hydrophobic liquid medium capable of undergoing mass transfer with the aqueous medium and apparatus suitable for use therewith are described. The extraction is effected in a mixer-settler (1) in which an a.c. electric field is applied to at least one of the upper and lower interfaces (13, 14) thereby to assist in controlling the position of that interface within the chamber. This results in improvement in the volumetric throughput and the single mass transfer efficiency and a reduction of aqueous and organic entrainment. <IMAGE>
Patent GB-2157400-A (GB)
Title: Reversing valve
Inventor: HERABAKKA JAKOB
IPC: F15B11/15
Filed: 1985-03-26
Abstract: A valve for controlling a hydraulic cylinder (26) for reversing the work stroke, comprises housing (1) containing a sliding spool (3) with a through bore (4, 4') containing a spring-loaded valve body (6) which co-operates with a seat (7) formed in the bore (4, 4') of the sliding spool (3), said slide (3) having recesses (5, 9, 22, 23) to co-operate alternately with channels in the housing when the sliding spool (3) has assumed one or the other end position. The valve seat (7) and/or the co- operating valve body (6) is formed to provide an imperfect seal, there being a relatively narrow open passageway between the two members, such that a flow of fluid under pressure through bore (4, 4') of the sliding spool (3), produces a pressure drop causing slide (3) to be moved from one end position to the other end position. Sliding spool (3) co-operates with a spring- loaded (16) piston (13) having a through bore (14) of substantially smaller cross section than the slide's bore (4, 4'), to act as a throttling passageway, the open end thereof in one end position of the piston (13) seating against a shoulder (24) on the valve housing (1) for closing off the throttling passage orifice, which causes the slide (3) to be returned to its starting position as soon as the flow of pressure fluid past the valve body (6) ceases. The valve is flow- controlled, requiring only a slight drop in pressure (2-3 bar) over the seat (7) in the through bore (4, 4') of the sliding spool (3) for holding the sliding spool (3) in one end position. <IMAGE>

Patent GB-2181295-A (GB)
Title: Optical gyroscope
Inventor: HEEKS JOHN STUART
IPC: G01C19/64
Filed: 1985-10-03
Abstract: An optical gyroscope with the operational attributes of a ring laser gyroscope and a conventional fibre optic gyroscope is comprised by a solid state laser diode (4), or equivalent high coherence source, whose output is tightly coupled into a coil (1) of low loss single mode optical fibre, so that the coil forms an optical resonant circuit for the laser diode and establishes a single frequency output of high coherence. On rotation of the coil about its axis, the degeneracy of clockwise and counter clockwise optical resonances is removed by the Sagnac effect, thus giving a frequency splitting of the diode output which is proportional to the rate of rotation. <IMAGE>
Patent GB-2182136-A (GB)
Title: Improvements in or relating to cooking hobs
Inventor: GOSTELOW BENJAMIN FRANK
IPC: F24C15/12
Filed: 1985-10-10
Abstract: A cooking hob accomodates top heating units e.g. burners and a lid movable between a fully opened position giving access to the burners and a closed position covering the burners. Associated with each of the gas taps is a switch that is closed when the associated tap is turned 'ON'. Another switch is closed when the lid is in a predetermined position, e.g. fully opened and closure of the two switches energises an electromagnet which operates a lid lock which prevents movement of the lid unless the 'ON' tap is turned off. Alternatively, the lid may be held in its fully opened position by a mechanism linked to the gas taps and which prevents movement of the lid from its fully opened position unless all the taps are 'OFF'.

Title: Detecting means for detecting the setting of an adjustable member
Inventor: VOLKER WOLFGANG
IPC: G01D5/34
Filed: 1986-02-13
Abstract: Detecting means for detecting the displacement or setting of an adjustable member, for example, a vehicle flap or rudder comprises a light source (1) which emits parallel light and the emitted light beam of which is split into a measurement and a reference beam. These beams are conducted through respective fibre-optic cables (6, 7) which extend to the member and back to respective light-sensitive elements (8, 9) arranged in the vehicle. The cable (6) for the measurement beam includes, in the proximity of the flap, an optical stop (10) which acts as a displacement angle pick-up and the light passage area of which is variable in dependence on the setting of the flap. The cable (7) for the reference beam may include an optical reference stop (11), the light passage area of which is variable by a setting motor (12) in dependence on the difference between the output signals of the elements (8, 9) until this difference is zero. The motor (12) can be coupled with equipment (15, 17) for determining the setting of the flap from the displacement of the reference stop (11).   <IMAGE>
