Title: Improvements in control arrangements for dynamo electric generators
Inventor: GOULD JAMES HAROLD
IPC: H02P9/12
Filed: 1953-04-22
Abstract: 728,333. Exciting dynamo-electric machines. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 22, 1954 [April 22, 1953], No. 11127/53. Class 35. Residual magnetism in the generator G of a Ward-Leonard set, is neutralized partly by the " suicide " connection of its field winding GF and partly by means of a polarized relay OCPR, responsive to any output current of the generator, causing the injection of a voltage tapped from a resistance BR into the field circuit in such a sense as to oppose the residual flux. The generator field GF is normally fed from supply S1, S2 through a control unit, e.g. a reversing potentiometer CM. It is connected through normally-open contacts C1, C2 of a changeover relay OCC which is energized when the control unit is set for operation, and normallyclosed contacts FD1 and RD1 of " forward " and " reverse " directional contactors OCFD and OCRD which are only selectively energizable through contacts PR of the polarized relay OCPR when the control unit is set for zero movement of the motor M, i.e. when contacts CMO2 are closed. In operation, movement of the control unit CM to energize the generator field, closes contacts CMO1, thus energizing relay OCC and opening its contacts C3, C4 and closing contacts C1, C2 so that the field winding GF is connected to the control unit. Return of the control unit CM to zero position cuts off the field energization and makes the " suicide " connection via contacts C3, C4, and also closes contacts CMO2 so that the tapped portion of resistance BR may be connected by contacts FD2, FD3 or RD2, RD3 to either side of the field winding depending on whether relay OCFD or OCRD is energized, i.e. depending on the sense of the generator current affecting the polarized relay OCPR.

Title: Improvements in means for treating cutaneous affections
IPC: A61M11/06
Filed: 1932-04-19
Abstract: 389,998. Suction-and-vapour treatment appliances. STRICKLER, A., 327, South 16th Street, Philadelphia, COMER, H., 431, State Road, Cynwyd, and ZIFFERBLATT, A. H., 5220, Lebanon Avenue, Philadelphia, both in Pennsylvania, U.S.A. April 19, 1932, No. 11200. Convention date, May 25, 1931. [Classes 81 (i) and 81 (ii).] A device for treating membranous affections comprises a source of medicative vapour, means for evacuating the space adjacent a portion of the membrane to be treated and means for causing a sudden rush of air through said source to said portion, whereby the vapour is projected forcibly upon the membrane. The device shown comprises a cylindrical casing 1 and a detachable end member 2, preferably of aluminium, the former being divided into two compartments 5, 6 by diaphragm 4. The casing is perforated for ventilation. A retort 9 of glass, preferably that known under the registered Trade Mark " Pyrex," resiliently supported in chamber 6, is adapted to be heated by an asbestos-sheathed coil 17. An insulating asbestos layer 15 is also provided. A pipe 25 connected to a vacuum pump branches into pipe 27 attached to the applicator nozzle 53, (Fig. 7) and into a pipe 26 opening into chamber 5. Opposite this opening and that of the inlet tube 12 of the retort 9 are rubber-tipped valves 31 and 30 respectively. These are connected by a yoke 38 and are spring-urged so that normally they do not press against the valve-seats. A valve-actuating pin 40 is pivoted on shaft 41 in which is screwed a pin 44. In operation, powdered medicinal substance is poured into the retort and the heating coil circuit is closed. The vacuum pump is started and the nozzle 53 is applied to the patient's skin. The nozzle, which may vary in shape according to the part of the body to be treated, is preferably ground to engage with the outlet tube 10 of the retort, and is provided with a tube 57 connected to the exhausting tube 27 by rubber tubing 58. The trigger 46 is now pressed, thereby closing the valves 30, 31 by means of a spring-urged rod 48 which engages with the pin 44. When the retort and nozzle are evacuated, the trigger is released, and the valves 30, 31 open, the former somewhat in advance of the latter due to the provision of a stronger actuating spring. Air rushes through the retort and projects the vapourized medicament on to the skin. The evacuating tubes may be cleansed by disconnecting the rubber tubing 58 from the tube 57, and drawing alcohol, and subsequently water, therethrough.

Title: Detector mechanism for multiple shuttle looms
IPC: D03D49/58
Filed: 1938-04-13
Abstract: 513,457. Picking - motions. SMITH, R. H., and SHACKLETON, G. W. April 13, 1938, No. 11292. [Class 142 (iii)] In a detector mechanism for multiple shuttle looms having a detector operated by the swell lever of the cell of a shuttle box about to receive a shuttle, the detector is coupled to a lever which is normally allowed to move about one pivot, but is moved about another pivot when the cell is occupied, to disengage the picking mechanism at the other side of the loom. The lever 9, Figs. 3 and 6, is pivoted at 9b, 9a to arms 19a, 19b, fixed respectively on the adjacent ends of aligned shafts 6a, 6b. An arm 10 on the other end of the shaft 6b is normally held stationary by a spring 10a so that a reciprocating rod 8b causes the lever 9 to oscillate about the pivot 9a. The shaft 6a is therefore oscillated by the arm 19a and an arm 6 on the other end of the shaft oscillates a bell-crank lever, Fig. 4, by means of a linkage. A pivoted catch 3 is normally clear of the path of the nose 4d of the lever 4 but if a shuttle is already in the cell, the swell lever raises the catch 3 and oscillation of the lever 4 is prevented. The shaft 6a is thereby held stationary causing the lever 9 to oscillate about the pivot 9b. The shaft 6b is consequently turned by the arm 19b thus raising the arm 10 which turns a lever 11, carried by the picking mechanism, out of the range of a rotary member 12 by which motion is imparted to the picking mechanism. The mechanism is duplicated so that the picking from each side of the loom is controlled by the detector at the opposite side.

Filed: 1973-03-08
Abstract: 1427361 Ignition timing ROBERT BOSCH GmbH 8 March 1973 [9 March 1972] 11319/73 Heading F1B [ Also in Division G 1] Adjustment of the timing of an I.C. engine ignition system of the mechanical or electronic circuit breaker type, is facilitated by an electromechanical transducer, e.g. a rotary or linear magnet 72 or solenoid-operated vacuum valve (75), Fig. 14 (not shown), acting on the circuit breaker pulse generator 20 and controlled by a feedback signal 17 and a control signal 15 derived from one or more signals 151-156 indicative of various operating variables of the engine. The operating variables are engine speed 151, engine acceleration 152, induction pressure 153, recirculated exhaust gas composition 154, angular position at the butterfly throttle valve 155, and a temperature 156 on or in the engine. All signals are fed to a function generator 10, which produces the control signal 15 which, together with the feedback signal 17, is fed to a servo-amplifier 70 and power amplifier 71 to produce the signal 18 controlling the electromechanical transducer 72 or (75). The servo force 19 is shown acting on a mechanical circuit breaker pulse generator to adjust the angular position of a breaker plate (757), Fig. 15 (not shown), or a rotary cam (209). The adjustment may be in addition to a centrifugal adjustment of the cam on its drive-shaft, and or a vacuum governor adjustment of the breaker plate. As shown in Fig. 1, the feedback signal is derived from the output signal from the circuit breaker 20 fed together with a signal derived from a pulse generator 80, to a bi-stable trigger stage 81. The output signal 823 from stage 81 is fed to an averaging circuit 82 and an amplifier 83 to form the feedback signal 17. The pulse generator 80 includes at least one ferromagnetic member 96 on the periphery of the flywheel 95 of the engine. According to Fig. 14, the feedback signal is fed by a potentiometer or inductive position sensor (76) mechanically connected to the breaker plate to move therewith. Circuit diagrams are provided for the operational parts of the block diagrams.

Abstract: 486,494. Controlling and lubricating change - speed gearing; relief valves. GENERAL MOTORS CORPORATION. Oct. 2, 1936, No. 11336 /38. Convention date, Oct. 16, 1935. Divided out of 484,301. [Class 80 (ii)] [Also in Group XXIX] . Change-speed gearing includes a pump, driven continuously from a driving part of the gearing, and delivering through a port 195 to a pistonvalve 200, which supplies a gear-lubrication main 220 at all speeds, but which supplies a speed-changing servo main 238 only above a critical speed at which the fluid-pressure causes the piston 200 to yield against an adjustable spring 201. At low speeds below the critical speed, pressure from the inlet 195 reaches the lubrication main 220 through annular spaces 203, 202, and a flat 214 on the piston, and also has access through a boring 208 in the piston to a space 209 below the piston. Pressure in such space, and later in the space 202, forces the piston upwards until, at a critical pressure, the piston uncovers an annular space 205, open to the servo main 238, communicating it with a pressure-space 204. At high speeds, the piston lifts further, Fig. 9, and opens a relief port 217, preventing further pressure rise. The servo main 238 continues to be supplied in this position through an inclined boring 213 in the piston. The Specification includes a description of the change-speed gear and its control, which description is an abridged version of that of Specification 484,301. Specification 484,463 also is referred to.
