Patent GB-1305404-A (GB)
IPC: G05D23/19
Filed: 1970-01-30
Abstract: 1305404 Automatic control of temperature MAEKAWA SEISAKUSHO KK 30 Jan 1970 4675/70 Heading G3R The temperature of a liquid in a storage chamber e.g. refrigerated or heated, is sensed by a sensor 3, Fig. 1 in the chamber and compared with a pre-set value in a bridge circuit 4, the imbalance analogue voltage of which is amplified and energizes one winding of a servomotor 7. The motor rotates an amount corresponding to the temperature deviation. The amount rotated is an integration of the deviation with respect to time and when the integrated value reaches predetermined levels, switches are successively closed by a cam 12 driven by the motor. Thereby relay circuits 24 1  to 24 n  are successively energized and these in turn control elements 2 1  to 2 n , e.g. compressors or heaters, until the deviation is reduced to zero. Thus, if the sensed temperature is too low such as when no heaters are ON, the motor rotates clockwise so that cam projection 13 tilts a lever 14 whereby contacts 18, 20 are closed and a positive error indicating signal is applied to energize an "addition" coil 25 1  of relay 24 1 . The relay is held ON by the resulting closure of holding contacts 28 1 . Relay 24 1  in turn closes a relay 30 1  to energize heater 2 1  and in addition closes a contact 25 2  allowing the next relay 25 2  to be energized by a positive error indicating pulse when the cam rotates a further 180 degrees and engages contacts 19, 22. Thereby a further heater 2 2  is energized and so on until the temperature deviation is zero. With n heaters energized, if the temperature sensed is too high the motor rotates anticlockwise closing contacts 19, 23 to apply a negative error indicating signal to energize a subtraction coil 26 n  in relay 24 n . Energization of coil 26 n  causes contacts 29 n  to open thereby deenergizing the corresponding addition coil 25 n  and hence the control relay 30 n  which disconnects heater 2 n . If the temperature is still too high the cam rotates to engage contacts 18, 21 to send a negative error indicating pulse to the 'subtraction' coil of the next preceding relay to effect disconnection of a further heater, and so on. The motor is such that the greater the deviation voltage the higher the motor speed and the faster the relays and heaters are switched. In the case of a refrigeration plant, Fig. 3 (not shown) the sensor 3 is in a low-pressure refrigerent vessel and the control relays operate compressor motors (52 1  to 52 3 ) successively to maintain the temperature sensed at a predetermined value.

Filed: 1971-04-26
Abstract: 1338615 Cine projection apparatus; cine cartridges R C ANDERSON 26 April 1971 11383/71 Heading G2E Cine projection apparatus includes a device for storing a stack of film cartridges, a device for locating each cartridge, in turn, in a projection position and a device for ejecting a cartridge from that position after projection. As shown the apparatus is located within a casing 16 and includes a screen 12, a self threading projector 11, take up reel 14 and loudspeaker 13. Film is supplied from one of a number of cartridges 20 stacked on rod 90. The cartridge 20 from which the film is presently being supplied is held in position by a retractable fork 62 and a film leader projecting from the cartridge 20 is supplied to the projector 11 by energizing solenoid 30 to place the drive wheel 34 of motor 32 in contact with it. When the film being projected is completed the solenoid 40 is energized to advance the drive wheel 44 of motor 43 through an aperture 75 in the wall of the cartridge 20. With the film projection mechanism disengaged, the motor 43 rewinds the film 25 back into the cartridge 20. Solenoid 50 is then energized to move friction grip roller 53 from its retracted position to contact the cartridge immediately above the one in the projection position. Solenoid 60 is then energized to retract the fork 62, permitting the cartridge in the projection position to drop down the rod 90. The fork 62 then returns to its unretracted position, the gripping roller 53 is then retracted, letting the cartridge it held fall into the projection position. Drive wheel 34 again supplies the film leader to the projector 11. The time taken for the films to be projected and rewound is set by controls before projection commences. As shown in Fig. 6 the cartridges 20 each consist of a dish 70, a reel 72 having a core 82 and disc 84 and a lid 71.

Abstract: 1339972 Variable capacitors R F OXLEY 11 Feb 1972 [15 Feb 1971] 4633/71 Heading H1M To provide low minimum capacitance in a tubular trimmer capacitor, the fixed electrode constituted by metallizing 12 on the outer surface of ceramic sleeve 10 is separated from tuning slug 22 in the minimum capacitance position by further coaxial sleeve 18 of material of relatively low dielectric constant and supporting the tuning slug whose wire terminal 30 is axially spaced from fixed electrode terminal 14. As shown, wire 30 embraces sleeve 18 and is located in a slot therein so as to extend into central bore 20 and engage screw thread 26 on slug 22. The wire thus functions as a lead nut for the slug and as a terminal, and being of low surface area there is little capacitance between it and terminal 14. The dielectric constant of the ceramic may be 80 and that of the other dielectric material, e.g. polyfluoroethylene, polyphenylene oxide and glass-fibre reinforced alkyd resins, may be 5.

Title: Battery chargers

Filed: 1972-01-12
Abstract: 1350015 Substation equipment STANDARD TELEPHONES & CABLES Ltd 12 Jan 1972 1443/72 Heading H4K A battery B in a telephone substation instrument is charged from the exchange over the telephone line only when the instrument is "on-hook" through circuitry which includes a full wave rectifier RB and a transistor VT3 which is made conductive by a time delay circuit that is enabled when the instrument goes "on-hook". When the instrument goes "on-hook" the exchange battery is connected to terminals L1, L2 and capacitor C2 is charged through transistor VT1. As capacitor C2 charges the base voltage of transistor VT2 rises until the Darlington triplet connected transistors VT2, VT2a, VT3 conduct to charge battery B. Resistor R3 in the emitter circuit of VT3 causes transistor VT4 to conduct if the voltage across it rises and then limits the base current of transistor VT2 to give constant current charging of the battery. When the instrument goes "off-hook", the potential across R4 drops and transistors VT6 and VT5 conduct to discharge capacitor C2. When ringing is applied the Zener diode DZ1 conducts to reduce the current in the Darlington triplet transistors and the capacitor C2 is discharged by transistors VT5 and VT6.
