Title: Thermistor of CRT degaussing circuit used to start switch-mode power supply
Inventor: BROOK MALCOLM
IPC: H04N9/29
Filed: 1987-08-07
Abstract: The series combination of de-gauss coils 3 and a PTC thermistor 4 is connected across main supply terminals 1, 2. Another PTC thermistor 5 is connected between terminal 1 and switch-mode power supply circuitry including diode bridge 6, isolating capacitors 7 and 8, power supply control unit 9 and an output switching transistor 10. Thermistor 5 is in thermal contact with thermistor 4 to ensure that the resistive value of thermistor 4 is maintained high during steady-state operation. Connecting thermistor 5 to the switch mode power supply allows the current through the thermistor 5 to provide the low voltage supply required by the power supply at start-up. This removes the need for a separate low-voltage supply circuit. <IMAGE>

Title: Monitoring movable equipment and goods
Inventor: CULLY CHRISTOPHER NELSON
IPC: G06Q10/00
Filed: 1987-11-09
Abstract: In a system for keeping track of the locations, and the movements between locations, of items of equipment (e.g. scaffolding components), each item 10 is marked on manufacture with a unique identifier 12, and its existence is electronically recorded in a register in a central digital processor store 42. Each movement (actual or intended) of an item is electronically monitored and recorded in the central store, so as to update the register as to the whereabouts of the item, and any intended future location. For that purpose, each location has an electronic reading head for scanning the identifier of each item entering or leaving the location, and relaying corresponding electronic signals to the central store. Interrogation units are provided at some locations for interrogating the central store to ascertain the location and/or other particulars of an item bearing a specified identifier. Relevant details of each item, including its owner, may be stored in the central store in association with its identifier. <IMAGE>

Title: Control system for hydraulic mine roof support
Inventor: PHILLIPS REGINALD ANDREW
IPC: E21D23/26
Filed: 1988-02-13
Abstract: A hydraulic mine roof support having hydraulic legs 10 and 11, is supplied with fluld from a low pressure, high volume, supply via lines 12, 13, 26 during the stage of compacting loose material, and with fluid from a high pressure, low volume, supply via line 24 only for the final setting of the support, after compaction of loose material has been substantially completed. Initially fluid at low pressure is supplied via lines 12, 13 and when there is a pressure build up in the lines 12, 13 valves 29, 31 will be opened against spring bias and allow further fluid at low pressure to pass via line 26, restrictor 34 and valves 29, 31 to the legs. This latter flow will continue even if a dead man's handle controlling lines 12, 13 is released. When the pressure in lines 12, 13 has reached a significantly higher value the valve 33 is opened against spring bias to permit high pressure fluid from line 24 to flow to the legs 10, 11. <IMAGE>

Title: Arrangements for converting rotary motion to linear motion
Inventor: STIDWORTHY FREDERICK MICHAEL
IPC: F01L1/12
Filed: 1988-09-12
Abstract: An arrangement for converting rotary motion of a camshaft (1) to linear motion of a reciprocable valve (9) employs a follower (25) which is rotatable with the camshaft about its axis of rotation within a hollow cam (18) having an internal cam profile (2P). The cam profile of the cam is held in engagement with a roller (3) carried by the follower and the valve is held in engagement with the cam, so that on rotation of the camshaft a linear motion is imparted to the valve either as a result of displacement of the cam transversely of the axis of rotation or as a result of displacement of the axis of rotation in the direction of movement of the valve. <IMAGE>
Patent GB-2227388-A (GB)
Title: Superconducting transistors
Inventor: PEROLD WILLEM JACOBUS
IPC: H01L39/22
Filed: 1988-10-05
Abstract: A superconducting transistor of the Gray type comprises first and second superconducting layers (1, 2) which form the emitter and base electrodes, respectively. Those layers have substantially the same bandgap. A first insulating layer (4) is sandwiched between the first and second superconducting layers. A third superconducting layer (3), forming the collector electrode, is separated from the second superconducting layer by a second insulation layer (5). The insulating layers are sufficiently thin for tunnelling to take place therethrough. In a conventional Gray transistor the bandgap of the collector layer is the same as that of the emitter and base layers, and it is found that in such a transistor the current gain decreases sharply as the operating temperature of the device increases. In the present invention the collector layer is formed of a material having a larger bandgap than the emitter and base layers. A set of current gain/temperature characteristics having substantially flat regions is thereby obtained.

Abstract: A semiconductor memory device comprises a plurality of normal memory blocks NB containing only normal memory cells and a redundant memory block RB containing only redundant memory cells. Normal column decoders NCD and normal row decoders NRD are associated with the normal blocks NB. A redundant column decoder RCD and a redundant row decoder RRD are associated with the redundant block RB. A block decoder 18 selects one of the normal blocks NB in response to first address signals (A0, A0 - A3, A3): the redundant column decoder RCD selects redundant columns to replace normal columns which contain defective normal memory cells, according to the output of the block decoder and second address signals (A8, A8 - A11, A11). The decoders NCD, NRD all are disabled by a redundant control clock generator 22 when a defective normal memory cell is addressed. One of the decoders NCD is enabled by the block decoder 18 when a defect-free normal memory cell is addressed. The device addresses the problem of reducing the power consumed in conventional memory devices. <IMAGE>
