Abstract: 809,703. Electromagnetic switches; contact members for switches. COMPAGNIE ELECTRO-MECANIQUE. Sept. 21, 1956 [Oct. 28, 1955], No. 29021/56. Class 38 (5). A moving contact 2 is pivoted at 3 on a member 4 and biased against an abutment 16 on the member by a coil spring 15, the member 4 being pivoted at 5 on a member 6 and being biased against an abutment 14 on the member 6 by a coil spring 13. On energization of the electromagnet (not shown) the member 6 is rocked about a pivot 7 away from a back stop 12 and the tungsten tip 10 of the contact 2 engages a similar tip 8 on the fixed contact 1, the curved contact surfaces then rolling on each other as the spring 15 is compressed and the contact 2 leaves abutment 16 and eventually silver plates 9, 11 engage. Further movement of the contact 2 on contact 1 is now impossible and hence further movement of the member 6 to its final position causes compression of the spring 13 to obtain adequate contact pressure (Fig. 4, not shown).

Title: Electrical control circuits
IPC: G05D23/24
Filed: 1972-06-21
Abstract: 1400843 Automatic control of temperature WAYNCO Inc 21 June 1972 29038/72 Heading G3 R In an automatic temperature control arrangement wherein current through a resistance heating element is monitored as a measure of its resistance and hence temperature, a monitoring circuit is provided which passes full load current pulses through the heating element to sense its resistance during periods when the main current feed to the heater is switched off. The application to the control of humidity or pressure, is also suggested. In Fig.2, a P.T.C. heater 25 is normally energized with full wave A.C. via S.C.R.'s 28, 37 controlled by the output from a differential amplifier, the firing of S.C.R. 37 charging a capacitor 38 the charge on which fires S.C.R. 28 in the next half cycle. The output of the amplifier has a magnitude and sense dependent upon the difference between its two inputs - firstly, a negative potential proportional to the actual temperature of heater 25 and derived from the volt drop across a sampling resistor 27 in series with the heater, during negative half cycles of supply; and secondly a positive potential proportional to the desired temperature and set-up on a potentiometer 34. The S.C.R.'s will switch off when the amplifier output drops to zero upon the target temperature being attained. However a pulsing circuit 23 will continue to periodically (once per second) fire the S.C.R.'s to send a current pulse through the heater 25 producing a volt drop across the sampling resistor for comparison with the reference temperature voltage and the output of the amplifier will take over control of the S.C.R.'s from the pulsing circuit if the sensed temp deviates below the desired value. In an alternative embodiment Fig. 3 (not shown); the sampling resistor (45) and a desired temp value resistor (64) are connected in opposite arms of a bridge (46). The imbalance output of the bridge controls the state of a flip-flop circuit which in turn drives a UJ oscillator circuit. The resulting pulse output of the oscillator circuit fires a triac in series with the load (54). When the bridge is balanced the UJ oscillator will be driven directly from the power supply source under control of an RC circuit (56, 56') and the oscillator will again fire the triac periodically to cause current pulses through the load for sampling its resistance.

Title: Improvements in and relating to electric motor control systems
IPC: B65H23/195
Filed: 1934-10-10
Abstract: 445,557. Automatic control of strip tension. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Oct. 10, 1934, No. 29043. Convention date, Oct. 11, 1933. [Class 38 (iv)] [See also Group XXXVII] The current input to a motor 16 is maintained constant by means of a vibratory contact regulator 25, and the setting of the regulator is varied by means of the current passing through a dynamo-electric machine 33 energized in accordance with the variable speed of a second motor 13, and having operating characteristics such that its current varies in accordance with the rate of change of speed of the motor 13. The motor 16 drives the reel 12 on which material is wound at constant tension as it is delivered from rolls 11 operated by the motor 13, and the system is such that the constant tension is maintained during acceleration and deceleration of the motors 13, 16. These motors are fed from a Ward-Leonard generator 14, and the machine 33 which operates a flywheel 34 whereby the desired characteristic is obtained, is included in circuit with an auxiliary coil 35 on the regulator 25 and fed from a generator 32 driven by the motor 13. A variable resistance 41 in shunt to the coil 35 is adjusted simultaneously with the tension-adjusting resistance 28 associated with the main coil 26 of the regulator. The coil 35 acts in opposition to the coil 26 during acceleration of the motors 13, 16, and cumulatively therewith during deceleration. In a modification, Fig. 2 (not shown), the generator 32 is omitted, the circuit comprising the machine 33 and the coil 35 being connected across the Ward- Leonard generator. In this modification also, the field of the machine 33 is fed in series with the field 23 of the motor 16, and the Ward-Leonard generator controller has further high speed positions in which the field of the motor 13 is varied, the regulator 25 also acting to maintain constant tension during this further speed-changing stage. In a further modification of the arrangement shown in the Figure, described with reference to Fig. 3 (not shown), the armature circuit of the motor 16 includes a booster generator driven at constant speed and having a field winding included in circuit with the machine 33. In this arrangement the tension of the material is maintained constant during speed changes, partly by the action of the booster generator, and partly by the regulator. The system is applicable in cases where the material is unwound from the reel under braking tension provided by the motor 16.

Abstract: 982,543. Resistors. PAINTON & CO. Ltd. Nov. 12, 1962 [Aug. 11, 1961], No. 29164/61. Heading HIS. The value of a film-type resistor is adjusted scoring the surface carrying the film to increase the resistance value to at least 75%, and preferably to 90 or 95%, of the desired value when the scoring is discontinued and is resumed at another area of the film surface remote from the area where the first scoring occurred, the second scoring operation increases the value of the resistance at a lower rate than the initial scoring operation and therefore allows a greater precision in the termination of the scoring operation at the required value. In addition, the second scoring operation may be carried out after the resistor.has been aged to stabilize the value. Fig. 1 shows a resistor having a cylindrical ceramic former with a layer of pyrolitic carbon or metal oxide deposited on its surface, whose value has been adjusted to say 90% of the required value by the grinding of the track 7 into the surface film, the grinding is terminated at A and resumed at B to grind a further track 9 to adjust the resistance to the desired value, alternatively the resistance may be reversed in the grinding machine after grinding track 7 and the subsequent grinding may take place from the other end of the resistor, Fig. 4 (not shown). The resistors may be in the form of flat plates, Fig. 5, having a series of grooves 57 ground into the resistance film the second grinding operation taking place, e.g. at 59, separated from the first grinding. The resistance film, as an alternative to those referred to above, may be composed of a mixture of tin chloride and 5 to 10% antimony chloride dissolved in hydrochloric acid and sprayed on a former previously heated to 600-700‹ C.

Abstract: 243,369. Choffel, C., and Jacquelin, A. P., (trading as Choffel et Jacquelin). Nov. 20, 1924, [Convention date]. Liquid raised up to solid; purifying and cooling gases.-In an acetylene, oxygen or other gas generator, the receptacle containing the solid material and the chamber containing the liquid are considerably restricted, the former where the liquid contacts with the solid and the latter above that part. The generator consists of an outer container c for water or other liquid, and an inner container a in which the solid is decomposed and the gas generated, the inner container a, Fig. 1, comprising an immobile open ended vessel having an enlarged head adapted to rest upon the upper edge of the outer container c and a restricted lower portion a<1> provided with a grid d on which the solid rests. Where the inner container narrows, the outer container is constricted also and affords such a small passage for the liquid that the effect on the level of the liquid in the outer container of disturbances caused by the decomposition in the inner vessel is minimized and external shocks are transmitted as little as possible to the liquid in the inner vessel. In another form, the head of water in the outer vessel c, Fig. 2, and consequently the pressure of the gas in the inner vessel a, are increased by forming the vessel with a cup-shaped top a<2> which communicates with the outer vessel c through tubes a<3>. The gas is led through a purifier e to a second purifier l disposed in a chamber k fixed on the inner face of the wall of the outer container. In both forms the grid d is of large mesh and grids m, n beneath it and of finer mesh catch any undecomposed particles which may drop through the grid. In modifications, the inner container makes an hermetic joint with the outer container and additional pressure is obtained either by connecting the outer container to an elevated external tank containing liquid, or by using a gas under pressure, which may be the gas evolved, in the cup-shaped portion a<2>.

[Also in Group XXXV] In a D.C. rolling mill motor, normally arranged to run at a constant speed but compounded so that its speed varies to a small extent with the load, the compounding is made adjustable to meet various load requirements. The motor armature is supplied from a Ward- Leonard generator 4, the field 4a of which is in series with an amplifying exciter 6 across busbars 7 supplied from an exciter 8. The control winding 6a of the amplifying exciter 6 is connected in series with an anti-hunt winding 4b on the generator, a resistor 10, and a tachogenerator 11 (driven by the motor) across the busbars 7. Deviation of the speed of the motor from a value predetermined by the voltage at the busbars 7 varies the resultant voltage applied to the control winding 6a to correct the deviation. A voltage proportional to motor current is tapped off resistor 13 and applied to a potentiometer 14 in turn supplying a magnetic amplifier 15 which applies this current component to resistor 10. The tapping on resistor 13 is gauged to field regulator 9 so that 'the proportion of the voltage tapped off is automatically increased as the regulator 9 is moved in the direction to increase the motor speed. Potentiometer 14 is manually adjustable. In a modification, the field winding of the motor (instead of the generator) is connected in series with the exciter 6 across the bus-bars 7.
