Abstract: 1,025,871. Automatic current control. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. May 2 1963 [May 23, 1962], No. 19834/62. Heading G3R. [Also in Division H2] In an electric motor control arrangement having a switching circuit, the mean motor current and therefore the torque is held close to a set value despite variations in the motor speed/time characteristic, while the instantaneous line current is prevented from exceeding a set value within the rating of the switching circuit. As shown, a D.C. motor M is connected in parallel with a diode rectifier D and is supplied from a source E via a switching arrangement S which comprises a commutating capacitor 5, a main controlled semi-conductor rectifier 1, an inductance <, a diode rectifier MR and an auxiliary controlled semi-conductor rectifier 6. The instantaneous motor current is sensed by a device 2, e.g. a transductor, chopper amplifier or Hall effect device, the output from which is applied to a comparator 7 which also receives a reference signal from a device 3; the difference signal from the comparator 7 controls a pulse generator 4 having outputs 8 and 9 which are applied respectively to the gates of controlled rectifiers 1 and 6. The arrangement is such that when the controlled rectifier 1 is fired, the supply voltage appears across the diode D and the motor M; when the instantaneous load current reaches a first set level a pulse appears at output 9 of pulse generator 4 and fires the controlled rectifier 6 thus allowing the previously charged capacitor 5 to extinguish the controlled rectifier 1. When the current falls to a second lower level, another pulse appears at output 8 to refire the controlled rectifier 1 to cause the current to build up again. The mean motor current is thus controlled close to a set value determined by the reference device 3; as applied to a battery driven propulsion system for a vehicle, the upper current level may be varied under the control of a foot pedal. The sensing device 2 may be connected to sense the current from the source E rather than the motor current, and the control means for the switch arrangement may comprise a semi-conductor switch device which can be turned ON and OFF by the application of appropriate signals to one or more control electrodes.

Title: Magazine pencil
IPC: B43K21/22
Filed: 1926-08-16
Abstract: 279,579. Feldman, E. D. Aug. 16, 1926. Pencil holders. - Relates to magazine pencil holders of the type in which the lead is advanced by means of a longitudinallyslidable gripping device. The magazine tube 3 is slidable in the outer casing 1, and is closeed at the lower end by a member 23. Preferably a second closure-member 22 is also provided for acting on the grippers. Secured in the lower end of the magazine tube is a cap 16, the upper wall 17 of which acts as a guide for the grippers 9, and also, by engaging with the upper end 7 of the lead guide-tube 6, serves to limit the downward movement of the tube 3. The grippers 9 slide in slots in the wall 17 of the cap 16 and also in slots in the end 7 of the tube 6, the upward movement of the grippers being limited by the engagement of the enlarged semi-circular parts 10 thereof with the end of the guide-tube. The lower end of the grippers is surrounded by a spring ring 15. The grippers are each provided with a pin 12 on each of which is pivoted a segment-shaped member 13 guided by means of an eccentric slot 14 on the other pin 12. To feed the lead forward, the operating-head 4 secured to the tube 3 is pressed in, thus carrying the gripper forward until the part 19 thereof engages the end of the tube 6. Further movement of the tube 3 causes the cap 16 to release the grippers, and the member 22 to act on the segments 13 and force the grippers out of engagement with the lead. Movement of the tube 3 is stopped by the engagement of the wall 17 of the cap 16 with the end of the tube 6. On release of the pressure, the spring 21 returns the parts to original position, the cap 16 carrying the grippers along until they are arrested by the engagement of the parts 7, 10, whereupon the continued movement of the tube 3 causes the cap 16 to abut against the segments 13 which turn on the pins 12 and, by the engagement of the pins 12 and slots 14, force the grippers on to the lead.
