Title: Improvements in or relating to variable resistance devices
IPC: H01C10/08
Filed: 1944-10-07
Abstract: 590,560. Regulating switches. WEST & CO., Ltd., A., and COUPAR, J. Oct. 7, 1944, No. 19271. [Class 38 (v)] In a variable resistance comprising two series of stationary contacts 1 connected to tapping points of two separate resistances and mounted in a circular manner around a bridging member, both series being co-axial and located in parallel planes ; the bridge member consists of a non-rotating co-axial insulating disc 3 carrying a contact ring 2, or alternatively separate contact members, on the outer edge, which engage the fixed contacts 1 at diametrically opposite points. The ring is mounted in a tilted position and contact is made from one fixed contact to the next by varying the plane of tilt of the contact bridge. A spindle 7 driven by worm gearing 9 and 10 has fitted to it a spider 6 which is tilted. Rollers 5 on the spider engage on the inside edge of the bridge member which is prevented from rotating by the roller 11 which engages a stop 11<1>. Each series of fixed contacts may extend for rather less than 180 degrees or alternatively may extend along the path of almost a complete circle.

Title: Improvements in or relating to guards for presses and like machinery
Inventor: HUMBER EDWARD JOHN
IPC: F16P3/14
Filed: 1968-04-24
Abstract: 1,218,412. Machinery safety devices. RADIOVISOR PARENT Ltd. 18 April, 1969 [24 April, 1968], No. 19277/68. Heading F2J. [Also in Division G1] For testing the electronic circuit of a light guard for a press, wherein a set of spaced apart electric lamps (not shown) shines on a corresponding number of series-connected photo-cells P1-P12 controlling a relay Rel, interruption of the guard de-energizing the relay to cause stopping of the press, diodes D1-D12 are connected to the anodes of respective photo-cells P1-P12 and the photo-cells and diodes are connected in circuit with changeover contacts Re2/3 and Re2/reeds of a relay Re2 so that when the relay Re2 is energized the photo-cells are connected in parallel, via the diodes, allowing a fault in any one to be detected. The output of the photo-cells controls the relay Re1 via an amplifier including transistors TR1-TR3. Initially all five relays Re1-Re5 in the control system are de-energized, and the guard lamps are dimmed. To prepare the system for operation, a reset button A is pressed to energize the relay Re2 to parallel the photo-cells. If there is no fault, relay Re1 is not energized, allowing relay Re4 to latch in. Pressing the " machine start " switch energizes relay Re3, bringing the guard lamps to full brilliance so that relay Re1 is energized and the press starting circuit is completed via terminal 16, contacts Re4/3, Re3/3, Re1/2, Re5/2, terminal 9, and contact S2. Near the end of the press cycle, a cam (not shown) closes a TEST switch 19, 20, 21 to energize relay Re2 for a period determined by the time constant of a capacitor C2 and a potentiometer P2<SP>1</SP>. Relay Re3 is de-energized via transistors TR5, TR6 to dim the lamps and open the press circuit. The photo-cells are paralleled. A fault would keep relay Re1 energized, breaking the holding circuit of relay Re4 to prevent further press operation. With the press standing idle, a fault, e.g. sun shining into the photo-cells, would energize relay Re1 to prevent energization of relay Re3 by the atart switch. A relay Re5 is operable by a key switch to by-pass the safety circuits, so that the press may be operated for tool setting.

Title: Improvements in or relating to pulsed radars
Inventor: SCHELISCH ERNST FRIEDRICH
IPC: G01S13/528
Filed: 1959-06-08
Abstract: 874,852. Pulse radar. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Nov. 3, 1959 [June 8, 1959], No. 19514/59. Class 40(7) A moving target indicating pulse radar comprises means for transmitting pulses at a varying pulse repetition frequency (p.r.f.), means for translating received echo pulses into corresponding signals stored in a device which is repeatedly scanned at a repetition frequency in fixed predetermined relationship with the varying transmitted p.r.f., means for scanning the storage device at a predetermined repetition frequency to pick off the stored signals, means for feeding the picked-off signals to the parallel input ends of two signal paths one of which has a delay time differing from that of the other by an amount equal to the period of scanning of the reading beam (or an integral multiple thereof), combination of the outputs of the signal paths in opposition to cause cancellation of signals arriving simultaneously at the output ends of both paths, and display or utilization means fed with the combined outputs. Random triggering of transmitter 4 is afforded by amplitude-selected and gated noise peaks from generator 1 and pulse generator 3. The transmitter radio frequency consists of the output of crystal-controlled oscillator 10, which runs at the i.f. of echo receiver 7, mixed in unit 9 with the output of receiver local oscillator 8. The receiver i.f. output is stored on cathode-ray tube plate 13 by a writing beam 14 the scanning deflection of which is produced by sawtooth generator 17 synchronized with generator 3 after a delay 18 which compensates for inherent delays in units 4, 6 and 7. Reading beam 15 scanning is controlled by sawtooth generator 20 and the output signals are fed to coincidence detector 25 via paths 22, 23, the latter of which includes a fixed delay 24 of one or more times the nominal scan period of beam 15. An electrode 27 is struck by beam 15 at the end of each reading scan and its output is fed to pulse generator 30 which gates amplitude selector 2 and to a known comparison unit 28 for automatic frequency control of sawtooth generator 20 by an output signal when a signal from electrode 27 is not simultaneous with, and cancelled by, a signal from unit 25. Further frequency control of generator 20 is exercised by phase comparator 29 to ensure that the frequency contained in the output signal from tube 12 is the same as the i.f. elsewhere. To produce a transmitted pulse leading edge in a predetermined phase relative to the intermediate frequency output of the receiver a bi-stable multivibrator acting as a delay device is inserted between amplitude selector 2 and pulse generator 3, Fig. 2 (not shown).

Abstract: 495,496. Actuation of switches. STANDARD TELEPHONES & CABLES, Ltd. July 14, 1937, No. 19538. Convention date, Jan. 30. [Class 38 (v)] [Also in Groups XXXIX and XXXVIII] Sound-reproducing apparatus, particularly for use as an announcing system on a battleship or in localities where abnormal sounds such as gunfire are likely to occur, comprises a closuremember located in a sound-passage communicating with a diaphragm and moved by the abnormal sound to open or close the passage to the external air. As shown in Fig. 1, the actuation of the electromagnet which operates the closure member 12 is controlled by diaphragms 20, 21 located near the abnormal sound source 26 and associated with switches 17, 18 so that in case of high or low pressure due to the sound, a circuit is completed over a relay 16 which locks up and forms an operating circuit for the coil 14 of the electromagnet which remains energized until its circuit is opened by a switch 25. In an alternative arrangement incorporating a microphone transmitter, the plug is normally in the closed position, and the electromagnet is energized by operation of the diaphragms 20, 21 located adjacent the microphone. The diaphragms 20, 21 may be replaced by a single diaphragm co-operating with switches on opposite sides or with a two-way switch.

The drum 12 is located in a housing 14 to which the rails 17, 18 are secured along each side edge of a slot 16. At each extremity of the helical part of the groove 13, the member 19 of moulded plastics material is rotated through an angle equal to twice the lead angle of each helical part at that point. Preferably, the portion 20 is generally rhomboidal in shape, the follower 21 is circular, rhomboidal or boltshaped and the portion 22 is generally cylindrical. The guide 23 is in the form of a notch 24 cut in a laterally-extending tongue. A lubricating liquid, e.g. mineral oil, forms a reservoir into which the drum 12 dips in the base of the housing 14 to distribute the oil to the relatively moving parts. A passage 27 is formed in the rail 17 for this purpose. Splash guards 28 are provided on the rails 17, 18. The plane mutually-engaging surfaces of the portion 20 and the rails 17, 18 may be formed with a V-shaped slot in each opposing pair of these surfaces to reduce friction therebetween.

Title: Improvements in gas turbine installations
Inventor: GARDNER THOMAS LOWTHIAN
IPC: F01D21/18
Filed: 1962-05-22
Abstract: 1,018,323. Gas turbine engines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 13, 1963 [May 22, 1962], No. 19684/62. Heading F1G. The invention relates to a method of protecting a gas turbine engine from the effect of sudden breakdown in the air flow through the compressor which utilises the abnormally rapid drop in the system air pressure to actuate a device for reducing the fuel flow. The device shown comprises a valve body 1 comprising a valve chamber 2 which is connected in the fuel supply line of the gas turbine engine by means of inlet and outlet ports 5, 6, fuel flow between the ports being controlled by a valve member 13 which co-operates with a seat 14. The valve member 13 is carried by a valve stem 15 which is connected at its lower end to an orifice member 9, the orifice member itself being mounted in a diaphragm 8 which forms a partition between two pressure chambers 4, 3. The chamber 4 is connected by means of a port 7 to a desired signal pressure such as compressor discharge pressure and this pressure is communicated to the chamber 3 by way of the orifices 10 in the member 9 and the valve takes up the position shown in which fuel may pass from the inlet port 5 through the chamber 2 and discharge from the outlet port 6. Should the compressor discharge pressure suddenly fall however, as occurs in the event of compressor stall or surge, the pressure in the chamber 3 does not fall at the same rate as that in chamber 4, the diaphragm 8 therefore moves downwardly and the valve member 13 closes so cutting off fuel flow to the engine. The interior of the bellows 21 is connected to a relief port 20. A screw 11 is provided for adjusting the rate of bleed from chamber 4 to chamber 3.
