Title: Actuating device for switchgear
IPC: H01H3/16
Filed: 1972-04-17
Abstract: 1391991 Retractive switches LA TELEMECANIQUE ELECTRIQUE 17 April 1972 [21 April 1971] 17729/72 Heading H1N An actuating device for a limit switch comprises a housing supporting a rockable shaft 2, two substantially coaxial members 11 and 13 having ends 15 and 16 engaging a flattened portion of shaft 2, resilient means 14 urging the members 11 and 13 against the flattened portion, said members 11 and 13 being relatively movable in an axial direction, whilst being prevented from relative rotation, and a first one 11 of said members being selectively engageable by one or both edges 6 and 8 of the flattened portion, in response to rocking of the shaft 2, in order to transmit the movement of the shaft to the limit switch (operating button 12 only being shown in Fig. 3), and a rotatable adjusting member 7 coupled to at least one of the coaxial members 11 and 13 for turning them and selecting whether said first member 11 is enengageable by only one or both of said edges 6 and 8, said adjusting member 7 being disposed in the housing about the coaxial members 11 and 13 and the resilient means 14 and being turnable from outside the housing via one or more openings 19. As shown, the members 11 and 13 have respective semi-circular portions 15 and 16 which may be cammed by the edges 6 and/or 8 when shaft 2 is rocked by an external lever (3, Fig. 1, not shown). Cylindrical member 7 has a knurled portion 5 accessible via openings 19 and is keyed at 9, 10 to member 11 whereby members 11 and 13 are conjointly rotatable, the flange 15 abutting the ends of portion 16. Member 7 forms a seating for spring 14 and sealingly bears on main housing 1, on which a head part 4 is scoured by screws (23, Fig. 2, not shown). A seal 41 is also provided between member 7 and head 4. When index marks 21 and 22 are aligned as shown, rocking of shaft 2 in respective directions causes edge 6 or 8 to cam member 11 to actuate switch button 12. If portion 5, and hence members 11 and 13, is turned through 90 degrees then rotation of shaft 2 in one direction causes edge 6 (or 8) to actuate the switch but rotation of shaft 2 in the other direction causes the other edge 8 (or 6) to act on member 13 only, and there is no actuation of button 12. Inadvertent rotation of member 7 during actuation of shaft 2 is prevented by the increased friction on surface 20. A ball detent arrangement (Fig. 7, not shown) between member 7 and shaft 2 serves to locate member 7 and also to lock it while shaft 2 is in an actuated condition. An alternative means of rotating member 7 may comprise bevel gearing on its upper edge co-operating with a bevel gear (26, Fig. 6, not shown) coaxial with shaft 2 and having a screwdriver slot (27) accessible externally of head 4.

Filed: 1969-04-08
Abstract: 1,267,421. Control of D.C. motors. GULTON INDUSTRIES Inc. 8 April, 1969 [5 April, 1968], No. 17842/69. Heading H2J.  In a battery powered vehicle, regenerative braking down to a low speed is facilitated by a voltage boosting circuit 33 connected to the motor 4, and a shunt field 4C is connected, for braking, to the otherwise series-wound motor. The boosting circuit comprises an inductor 35 connected between the positive armature terminal and the battery via a diode 40 and switched periodically by thyristors 43, 44 and 47, 48 with a commutating capacitor 41. The thyristors are fired in alternate pairs by a circuit 45 which comprises a relaxation oscillator and bi-stable circuit (Fig. 3, not shown), the frequency of the oscillator and hence the amount of braking being adjustedby a brake pedal controlled rheostat 26. In an alternative arrangement (Fig. 6, not shown) the average current through the inductor is kept constant for a given pedal setting by an operational amplifier which adjusts the frequency of the oscillator according to the volt-drop across a resistor in series with the inductor. The brake pedal also controls a rheostat 29 in the shunt field circuit and a mechanical brake 22 through a lost-motion link so that it is effective only in the final stage of braking. Change-over from driving to braking is effected by a relay K1 energized by first movement of the brake pedal. The speed of the motor during driving is controlled by a thyristor 6 having a turn off circuit 10 which comprises two pairs of auxiliary thyristors and a commutating capacitor (Fig. 4, not shown) which are fired in alternate pairs by a square-wave generator. Triggering pulses for 6 are produced by a relaxation oscillator and unijunction circuit whose operation is synchronized with the square wave generator, the firing instant and hence pulse width being controlled by an accelerator operated rheostat in the oscillator circuit. Some shunt field current is provided through resistor 5 to prevent runaway on no load.

Title: Motor speed control apparatus for runout tables
IPC: H02P5/50
Filed: 1964-05-01
Abstract: 1,012,392. Control of several D.C. motors. WESTINGHOUSE ELECTRIC CORPORATION. May 1, 1964 [May 10, 1963], No. 18178/64. Drawings to Specification. Heading H2J. In a strip rolling mill, speed regulators and generators are energized initially to control the operation of stand drive motors at a threading speed, determined by the voltage of a " thread " bus-bar associated with an exciter whose output increases in a linear manner. When the workpiece has passed through each of the stands, and passes a run-out table to enter a coiler, a device responsive to the change of load on the coiler-motor provides a signal to sequence control apparatus. This causes the speed regulators for the stand drive motors and the run-out table motors to be connected to a " run " bus-bar for operation at higher speed. Contactors associated with the " run " bus-bar are first closed, and, after a time delay, contactors associated with the thread bus-bar are opened, the speed of the motors being increased in a linear manner. After the workpiece passes through each run-out table motor-section, the speed of that section is decreased to the threading value until a second workpiece enters the coiler. Each stand comprises a roll force Denser which provides a signal to the sequence control apparatus to decrease the speed of the stand when the workpiece has passed therethrough. When an increased load is taken by the coiler motor, which is energized through a generator, a tension regulator is connected to the " run " bus-bar instead of the " thread " bus-bar. As the end of a workpiece leaves a particular table motor section, that section will change from high to low speed operation in accordance with the passage of the strip as sensed by a pulse source operative with pinch rolls. The signals from the pulse source are counted to provide control signals each corresponding to the passage of a predetermined length of strip. Each control signal disconnects a speed regulator for a particular section of table motors from the " run " bus-bar and connects it to the " thread " bus-bar. After the strip has passed the last section of table motors, the counter is re-set.
