Title: Improvements in control system for a synchronous motor
IPC: H02P1/46
Filed: 1964-06-10
Abstract: 1,058,120. Control of A.C. motors. GENERAL ELECTRIC CO. June 10, 1964 [June 17, 1963], No. 24080/64. Heading H2J. Direct current obtained by rectifying the output of an A.C. exciter 10, 12 is applied selectively to the field winding 16 of a synchronous motor through controlled rectifier 24, the exciter armature and motor field winding being mounted on the same shaft, together with components in the control circuit. The rectifier 24 prevents the application of field excitation until synchronous speed is approached, discharge resistor 20 being connected across winding 16 during the starting period. The field excitation is removed and discharge resistor re-connected if the motor pulls out of synchronism, the motor being resynchronized if conditions permit it to accelerate to synchronizing speed. When the induced field voltage exceeds a predetermined value, Zener diode 32 renders rectifier 30 conductive to connect resistor 20 across winding 16. As the slip frequency is reduced, capacitor 42 becomes charged sufficiently to fire diode 44, the induced field voltage being clipped by resistors 36, 38, and Zener diode 28. Capacitor 46 is prepared for discharge through unijunction transistor 48 to pulse transformer 56 which renders rectifier 24 conductive. Transistor 48 is triggered by diode 99 at the desired rotor phase angle. The motor may accelerate so rapidly that the optimum angle never occurs at the preselected slip. To meet these conditions, a timing circuit comprises resistor 58 and capacitor 60 which discharges through diode 62 to pulse transformer 56. When the field winding 16 is excited initially through the rectifier 24, rectifier 30 is non- conductive. The resistor 20 may be reconnected, however, if high field voltage transients occur. The rectifier 30 is turned off by momentarily turning off rectifier 24 by means of capacitor 72, inductor 100, and rectifier 70. Diode 66 is fired by capacitor 64 to energize primary winding 68. Secondary winding 69 turns on rectifier 70 so that winding 16 is energized through capacitor 72. The rectifier 24 is turned off, the capacitor 72 discharging and then charging in the reverse direction. Rectifier 30 is rendered non-conductive, the rectifier 70 being turned off when the exciter phase voltage reverses. Rectifier 24 is then restored to conduction. An alternative circuit for charging capacitor 46 comprises capacitor 78, resistor 80, and Zener diode 82. When the exciter frequency and speed are low, indicating that the motor is out of synchronism, capacitor 90 fires transistor 92 to turn on rectifier 94 so that primary winding 96 is energized from capacitor 46. Rectifier 70 is made conductive by secondary winding 97 so that rectifier 24 is blocked. Rectifier 93 prevents the fieldremoval circuit from operating during the normal synchronizing operation.

Title: Improvements in or relating to vessels for impregnating cables
IPC: H01B13/30
Filed: 1931-08-07
Abstract: 389,084. Impregnating cables. PINTSCH AKT.-GES., J., 71, Andreasstrasse, Berlin. Aug. 27, 1931, No. 24091. Convention date, Nov. 29, 1930. [Class 36.] An apparatus for impregnating cables with oil or bitumen &c. consists of a vessel a, Fig. 3, having an inlet pipe b for the oil, and a suction pipe c opening into a centrally disposed displacer d which communicates with the vessel a through a valve e. The valve e consists of a plate f, Fig. 1, mounted on a spring-loaded spindle provided at the lower end with a piston h. The valve is closed by passing oil through a tube i under pressure, whereby the piston is forced downwards. For an alternative form of valve, a similar spring-loaded plate is forced downwards by a member operated by a hand-wheel mounted on top of the vessel a. The cable to be treated is placed in the vessel a, which is then evacuated through the pipe c, whereby the cable is freed from moisture. The oil is then admitted through the pipe band rises to the level of the valve e, which is then closed. Cock t is opened and the vessel is completely filled with oil by a pump connected to the pipe b, which thereafter generates sufficient pressure in the tank to impregnate the cable.

Title: Extruder-roller die
IPC: B29C48/08
Filed: 1967-05-24
Abstract: 1,139,400. Extrusion-roller dies. FARREL CORP. 24 May, 1967 [26 July, 1966], No. 24091/67. Heading B5A. In an extrusion-roller die including an extruder 15 supplying plastics or rubber material to a pair of rolls 13, 14 mounted in a movable frame 22 as described in Specification 998,725, the frame is yieldingly connected to the extruder and there is a sensor for detecting excessive relative movement therebetween, brought about by pressure of the material delivered to the rolls. The resilient connecting means comprises two plungers (32) normally urged outwardly from and held respectively in members (27), 28 on either side of the extruder by Belleville washers (33), Figs. 4, 5 (not shown). The extruder and frame are normally locked a predetermined distance apart by two hydraulically actuated, vertically reciprocating keys (43), each acting laterally and sliding in a channel of the extruder, and in the locked position a switch (49) comprising the sensor is closed by a stop (50) on a column 25 of the frame. In operation, the frame 22 is moved to the extruder until a block (52) on each of columns (25), 26 contacts a portion (53) of a bracket (47) supporting an hydraulic cylinder (46), which then acts to lower the key to a locking position, when a lower limit switch (55) signals that locking is effected and an upper switch (55a) is allowed to close. If pressure builds up, relative movement is opposed by the plunger (32) until a limit is reached when the stop (50) allows the switch (49) to go "off", which de-energizes a relay (R) to de-energize a motor (M) driving the extruder screw 16. When the arm (49) is again closed by the stop (50), the motor is re-energized. In a modification, a strain gauge (60) comprising the sensor in a bridge circuit detects the relative movement. Switches (55), (55a) are in the motor circuit and prevent operation of the extruder and rolls until locking is effected.
