Patent GB-763483-A (GB)
Title: Improvements in coincidence detection apparatus
IPC: H03K19/12
Filed: 1954-03-15
Abstract: 763,483. Magnetic amplifiers. REMINGTON RAND, Inc. March 15, 1954 [March 16, 1953], No. 7489/54. Class 40 (4). A transductor operating as a pulse coincidence detectorhas a single core 1 which possesses a substantially rectangular hysteresis characteristic and high remanence, the core being cyclically magnetized to saturation and then partially demagnetized by the alternate application of current pulses to load and signal windings 2 and 3 respectively. As shown in Fig. 1, magnetizing pulses are applied to the load winding 2 from an A.C. source Eac over a half wave rectifier 17 and a load 19, and the whole of a pulse is required to drive the core to saturation whenever substantial demagnetization occurs during the preceding half cycle. An A.C. source Ez, which may have a common origin with Eac, supplies demagnetizing half-wave pulses to signal winding 3 over parallel coincidence circuits each comprising a rectifier 15, 16 and a low impedance pulse source 11, 12. Voltage Ez causes substantial demagnetization of the core unless opposed by the coincident reception of pulse voltages at 11 and 12. A reduced degree of demagnetization arises when Ez is partially neutralized, and the subsequent magnetization by Eac during the next halfcycle in winding 2 causes early saturation which results in a substantial increase in current flow through load 19. The necessary low impedance across each pulse source 11, 12 may be provided by a shunt circuit, Fig. 3, comprising a rectifier 20, a high impedance 22 and a D.C. voltage 21. In a modified detector, Fig. 4, two single-core transductors are arranged with rectifiers 25-32 to provide coincidence detection of input signals occurring at any time in a cycle of operation and a full wave rectified output.

Title: A pressure indicating device
Inventor: GUTKOWSKI JANUSZ
IPC: H01H36/00
Filed: 1967-02-17
Abstract: 1,217,677. Pressure indicators. BTR INDUSTRIES Ltd. Feb.16, 1968 [Feb. 17, 1967], No.7645/67. Heading G1L. A device for indicating when a fluid-pressure exceeds a predetermined value comprises a sensing member movable in response to the pressure of the fluid and an indicator member 3, the sensing member having two pole pieces 18, 20 of magnetic material and the indicator having a pole piece 7 of magnetic material. A sleeve 2 is shaped in a housing 14 by a body 1 to form a seal on the face 16 of the housing. The sensing member comprises a pot 25 of magnetic material containing a non- magnetic sleeve 26 and a bar magnet 4. The free ends of the magnets 4, 25 abut the fixed pole pieces 18, 20 which are separated by a non magnetic ring 19 and the magnetic circuit is completed by the pole piece 7. When the pressure, applied to the sensing member via bores 30, 31, is sufficient to overcome the magnetic attraction between the sensing member and the pole pieces 18, 20, the biasing of a spring 8 and the low pressure applied via a bore 28, the sensing member is moved away from the indicator 3 thus breaking the magnetic circuit and allowing the indicator to be urged outwardly by a spring 9. The sensing member slides in a PTFE seal 16 and returns automatically to its original position on removal of the fluid-pressure but the indicator must be returned manually. The high and low pressures applied at 30 and 28 respectively may be the pressures upstream and downstream of a filter assembly.

Title: Improvements in or relating to electric time switches
IPC: G04C23/22
Filed: 1945-03-27
Abstract: 603,159. Time switches ; snap - action switches. VENNER TIME SWITCHES, Ltd., HORGAN, W. F., and FOX, L. W. March 27, 1945, No. 7705. [Class 38 (v)] A time switch has an insulating casing consisting of a main portion 1, 2, which completely encloses all " live " parts but exposes the timing element or dial 72, and a cover (not shown) which covers the timing element 72. The portion 1 carries terminal sockets connected to the supply leads and engaged by plugs on the portion 2. The fixed contacts 32, 33, co-operate with moving contacts (not shown) mounted on an insulating arm 42 pivoted at 43 and carrying a lug 47, the moving contacts being biassed open by a spring 51. The dial 72 carries two hands 73, 75, and pins 74, 76, and is driven counter-clockwise (as viewed in Fig. 3) by a clockwork or synchronous motor 22. During its rotation, the ON " pin 74 engages two tongues 66a, 68b, Fig. 13, and moves them outwards. Movement of the tongue 66a causes a lever 66 to stress a spring 65 also attached to a bell-crank lever 59, 60 pivoted at 64, movement of which lever is prevented until a part 69a on the lever 68 moves from behind a lug 60a, when the lever 59, 60 moves counter-clockwise, taking with it a lever 57 and the lug 47, to close the switch. Further movement of pin 74 allows the levers 66, 68 to return to their normal positions where part 69a catches over the lug 60a to latch the switch closed. The switch is opened by the engagement of the " OFF '' pin 76 with a tongue 68c on the lever 68, thereby unlatching the lever 59, 60, and stressing a spring 70 which returns the levers 57, 59, 60 to their normal positions, thereby releasing the moving contacts which are opened by spring 51. A push-button (not shown) is provided to enable the switch to be operated manually. The button engages a sliding plate 77 carrying a pivoted lever 79 with two operating points 79a, 79b, one of which (79b) (when the switch is '' open ") engages a part of the insulating arm 42 to close the switch, which is latched by the lug 47 moving into a notch 54b on a lever 54. The next inward movement of the button causes the point 79a to engage a lever 62 which moves the levers 54, 57, to the right to release the lug 47 to open the switch. The arm 42 also carries an indicator arm 48 viewed through a window in the casing. With D.C., a blow-out coil 36 is arranged near the contacts to extinguish any arcs that may form.
