Title: An electrical control system for stabilising at a desired value, a variable factor
IPC: G05B11/01
Filed: 1950-07-25
Abstract: 681,757. Automatic temperature control systems. SIEMENS & HALSKE GES. July 25, 1950 [July 25, 1949], No. 18581/50. Class 38 (iv). A control system for stabilizing at a desired value a variable factor, e.g. the temperature of an oven, comprises a first device having an input which varies in accordance with variations in the factor to be controlled, e.g. the temperature of the oven, a second device having an input which varies in accordance with a second factor which affects the first factor, e.g. the heating current to the oven, and an element responding to the joint influence of the two factors which effects stabilization through an electronic valve circuit. As shown, the output of a thermocouple 1, located in an oven 2, is applied, after comparison with a reference voltage developed across a setting potentiometer 3 to a coil 4, and a measure of the current supplied to the oven heater 8 is developed across a resistor 7, the voltage so developed being compared with that from a battery 6 and applied to a coil 5. The coils 4 and 5 control a moving vane 11 which varies the output of an oscillator 12 in turn controlling the periods of conductivity of a thyratron 9 in series with the heater 8 supply circuit. In operation, should the temperature in the oven rise, say, the coil 4 will effect movement of the vane 11 in a direction such that the heating current is reduced. Such reduced heating current affects coil 5 in such a manner that it influences the vane 11 in a sense opposite to the influence of the coil 4, thereby preventing hunting.

Title: Improvements in and relating to gas-blast electric circuit-breakers
IPC: H01H33/14
Filed: 1944-09-28
Abstract: 584,002. Air - break switches. AKT. - GES. BROWN, BOVERI, & CIE. Sept. 28, 1944, No. 18604. Convention date, Sept. 2, 1943. [Class 38 (v)] A gas - blast circuit - breaker in column form with multiple series connected points of interruption and parallel impedances for controlling the distribution of voltage over the points of interruption, has its extinguishing chambers, impedance supports, and supporting insulator built up of insulating sections having the same length but different internal diameters. This enables the same insulating section to be used for building up different parts of circuit - breakers of various sizes, thus reducing the number of sizes that have to be kept in stock. Thus in. Fig. 1 the extinguishing chambers a<1>-a<5>, the impedance supports b<1>-b<5>, and the support c<1>-c<5> are composed of insulators of sizes A, B, C, of the same length but of internal diameter to suit the requirements. The insulator sections e, of anv bracing member that may be required, are solid. The fixing heads of all the insulators may be the same so that standard fittings may be used. The Specification as open to inspection under Sect. 91 states that the stock keeping may be further simplified by the use of only one insulator and insertion pieces of the bore required. This subject-matter does not appear in the Specification as accepted.
Patent GB-810460-A (GB)
Title: Improvements in or relating to control apparatus for power operated presses and the like
IPC: B30B15/14
Filed: 1955-06-28
Abstract: 810,460. Transmitting mechanical power; electromagnetic clutches and brakes. IGRANIC ELECTRIC CO. Ltd. June 28, 1955 [July 1, 1954], No. 18632/55. Classes 35 and 38 (4). Relates to apparatus of the type described in Specification 804,835 in which, however, the clutch coil 19a and the brake coil 17a are respectively supplied through the power windings 26, 30, and 27, 31, of magnetic amplifiers 28, 29. Depression of both push-buttons 57, 58 energizes control winding 37 of amplifier 28 to oppose the bias winding 34 so that clutch coil 19a is fully energized. At the same time, the control winding 49 of amplifier 29 is disconnected whereby the bias winding 47 becomes effective to turn the amplifier off and to de-energize the brake coil 17a. The friction brake is released by energizing coil 14, and the maximum driving torque is developed to accelerate the press downwardly. As the ram approaches the work, limit switches are actuated to excite coil 49 and to energize brake coil 17a, and the excitation of control winding 37 is reduced by the insertion of resistors 39, 40 in circuit so reducing the current passing through clutch coil 19a. This results in slow down of the ram as it comes into contact with the work. Thereafter, other limit switch actuation disconnects winding 49 to deenergize brake coil 17a whereupon resistors 39, 40 are disconnected in rapid succession from the circuit of winding 37 to again afford maximum energization of clutch coil 19a, and thus drive the press ram at higher speed through the remainder of the forming operation and back towards its upper normal position. As the ram reaches its upper position, the clutch coil is quickly de-energized and the brake coil fully excited. Shortly thereafter, time-delay contacts become effective to apply the friction brake.

Abstract: 979,418. Fluid-pressure brakes. MIDLAND-ROSS CORPORATION. May 24, 1961, No. 18697/61. Heading F2F. [Also in Division G3] A differential pressure motor for operating the master cylinder piston 30 of an hydraulic brake system and comprising an annular diaphragm 49 clamped between plates 47, 48 is connected to the piston 30 through a rod 18 and a plurality of radially disposed levers 82 which react on the manual input member 36 to provide " feel " after an initial movement of the motor. With the parts in the positions shown, vacuum from the intake manifold of an internal combustion engine connected at 24 is effective both in a chamber 23 and, through passages 66b, 66, 63, in a chamber 22 so that the motor diaphragm 47, 48, 49 is held by a spring 116 in the rightward position and the levers 82, which are embedded at their outer ends in a rubber ring 86 and bear against a ring 84 secured to the boss of the diaphragm and against a member 91 mounted on the rod 18, are urged by a rubber &c. reaction ring 90 away from engagement with a member 88 on the member 36. When the member 36 is moved inwardly a valve seat 68 carried thereby is brought into engagement with an annular, rubber &c. valve member 76 to interrupt communication between the chambers 22, 23. Further movement of the member 36 lifts the valve member 76 away from a seat 72 to connect the chamber 22 to atmosphere through openings 64, the interior of a bellows 56, and a filter 59, so that the diaphragm is moved to the left. The resistance to movement of the master cylinder causes the levers 82 to be deflected, compressing the rubber reaction ring 90, until their inner ends engage the member 88 to provide " feel " for the operator. The seat 72 moves with the diaphragm so that the movement of the latter corresponds to the movement of the member 36. Specification 979,419 is referred to.

Abstract: 1,044,772. Films. TOYO RAYON KABUSHIKI KAISHA.May 10, 1963 [May 10, 1962], No. 18727/63. Heading B5B. A process for stretching a thermoplastic film comprises moving the film longitudinally while subjecting it to preliminary general heating, preliminary local heating and, optionally, preliminary transverse stretching so as to cause softening and/or necking in a longitudinal region substantially parallel to the direction of movement of the film, and then subjecting the film to a main transverse stretching. The main transverse stretching may be effected with the aid of further local heating. In one embodiment, Fig. 2, a moving film is subjected to preliminary general heating in zone a, a<SP>1</SP>, b, l<SP>1</SP> by hot air, and to preliminary local heeting by infra-red heater 1-2. In the main transverse stretching zone b, b<SP>1</SP>. c, C<SP>1</SP>, further local heating is carried out by infra-red heaters 3-2 and 4-2. In other arrangements, one or both edges of the film in zone a, a<SP>1</SP>, b, b<SP>1</SP> are locally heated, and one or more heaters are arranged diagonally or in V-formation in zone b, b<SP>1</SP>, c, c<SP>1</SP>. The heaters in the two zones of the film are continuous. The preliminary general heating is suitably above 70 C., and the ratio of preliminary stretching, where applied, is not more than 1.7. In examples, films of polypropylene, and polycapramide are stretched to products of uniform thickness.

Filed: 1939-06-28
Abstract: 530,609. Feed mechanism for grinding machines &c. SMITH, E. R. June 28, 1939, No. 18864. [Class 60] [Also in Group XXII] A lathe or grinding machine is provided with feed mechanism wherein a slide is actuated by a cam mounted on a shaft which is rotated through part revolutions at pre-determined points in the cycle of the machine by means of a pinion on the cam shaft and a number of segmental gears successively engaging the pinion. In one form a longitudinal carriage 10 moves on guides 11 and 12 and carries a cross slide 14. A feed shaft 20 carries a splined worm 21 driving a vertical shaft 31 through a worm gear 22 mounted loosely on a cam shaft 26 and spur gearing 24. Segmental gears 33, 35 may be secured in different angular positions on a gear 30 by screws 37 and each segment intermittently imparts a half revolution to a pinion 40 on cam shaft 26 which carries a fixed cam 42 engaging rollers carried by a member 45 adjustably secured to the cross slide, the slide being adjusted relatively to the cam mechanism by a screw 48. To hold the cam shaft between successive movements a latch plate carrying a locking tooth 56 is mounted on a bell crank 58 pivoted at 59 the tooth being normally engaged with the pinion 40 by a spring plunger 60 and being, disengaged by one of the cams 65, 63, carried by the segments prior to the engagement of the pinion 40 by the corresponding segment. The feed shaft speed is such that the shaft 31 rotates once for each movement of the carriage 10 and during this movement the cross slide is first advanved and then retracted by the cam. By adjustment of the gears 33, 35 points in the cycle at which the cross feed and withdrawal occur and the duration of the dwell in the working position may be varied. By modification of the cam 42 and the number of segments other cycles may be obtained. Thus the cam 42a shown in Fig. 11 may be employed to give two different working positions in addition to the withdrawn position.

Abstract: 376,490. Starting. BLACKSTONE, G. M., CARTER, F., and CARTER, E., Rutland Engineering Works, Stamford, Lin. colnshire. July 2, 1931, No. 19072. [Class 7(v).] For relieving compression at starting or during slow running, an inertia catch 3, pivoted at 4 on a fixed part of the engine and acted upon by a spring 5, enters a groove in a collar 2 on the exhaust or air valve push rod 1 or the valve rocker lever and holds the valve open. When the speed of the engine increases, the catch fails to enter the groove and the valve closes normally. One wall of the groove and the corresponding face of the nib of the catch 3 are bevelled to allow the nib to be pushed out of the groove when a sufficient speed is attained. The Provisional Specification states also that a lever may be employed to open the valve sufficiently to allow the catch to enter the groove, and an arm on the lever may move the fuel injection plunger into an inoperative position.
