Title: Improvements relating to the control of continuous electro-magnetic interrupters
IPC: H03K17/288
Filed: 1926-10-22
Abstract: 260,291. British Thomson-Houston Co., Ltd., (Assignees of Carter, E. F.). Oct. 22, 1925, [Convention date]. Thermionic valve circuits. - In order to close and open a circuit 3 intermittently, auxiliary contacts 12 on the interrupter are arranged to control the potential of the grid 7 of a threeelectrode thermionic valve through which the actuating coil 4 is supplied, and the charging of a condenser 10 across the grid circuit serves to determine the time-interval between opening and closing. With the arrangement as shown, the negative potential on the grid is gradually decreasing owing to the discharge of the condenser 10 through the resistance 11. When the potential is low enough the valve is " open," that is to say it conducts, and, in consequence, the winding 4 is energized and the circuit 3 is completed by the bridge 2. The condenser is now connected to the suorce 19 and is charged at a rate depending on the adjustment of the resistances 11, 20. The grid gradually assumes a potential which causes it to " shut," whereupon the relay opens again. This action is continuous, the timing being dependent on the adjustments of the resistances. An auxiliary relay 15 which closes when the bridge 2 closes (by current supplied from the filament battery) is employed to ensure that the full voltage 19 is applied to the condenser during the latter part of the charging period.

Abstract: 266,657. Ackley, A., and Plum, S. H. Dec. 24, 1925. Delivery apparatus.-Sheet gripper mechanism, which is particularly applicable to platen machines for delivering sheets as described m Specification 266,493, comprises a slidably mounted gripper carriage 191, grippers 230, 241 mounted thereon, a sliding member 239 for opening and closing the grippers, and a movable member 226 for maintaining the grippers in open position as they approach the platen to receive the printed sheet. The carriage 191 is mounted and reciprocated on guides 195 mounted beneath a feed board 18, and is constructed as described in Specification 219,916, [Class 100 (ii), Printing processes &c.], but is reciprocated from a pivoted cam 206 which is oscillated by the driving crankpin 207 of the platen press. The cam is designed to impart a rapid initial movement to the delivery stroke of the gripper, with a slight dwell at the end of the stroke to permit ejection of the sheet. As the grippers reach the delivery position they are opened by a cam 240<a> on the member 239 which is moved in grooves in the grippers when a roller 237 on a bell-crank lever 236 engages an adjustable cam member. The member 239 ejects the printed sheet. A catch 226 on a spring-controlled bell-crank lever 224 holds the grippers open until a slide 220 with an adjustable head 221 engages the face of the platen and releases the catch 226. When the member 239 has been returned to its inoperative position by a spring 249, the grippers close under action of a spring 247 and grip the sheet which is registered against pins 233.

In a control system for the lifting winch 5, Fig. 1, of an automatic gripper 1 adapted to be engaged or disengaged from articles 32 after repeated reciprocations of the lifting cable 3, switches are provided for stopping the winch 5 at the engaging or disengaging positions and for starting cyclical movements of the cable which continue until the article is engaged or released, whereupon the winch is automatically restarted. In the particular example the cable 3 passes over a pulley 22 capable of vertical reciprocation in guide ways 27 by a crank mechanism 24, 25 driven from an electric motor 26 and normally retained in the uppermost position. The cable 3 also passes over a pulley 13 mounted on a double pivoted crank 40, 42, Fig. 2, yieldingly held by springs 17a, 18a and adapted to operate switches L, M which stop the winch when the tension is either released or reaches a predetermined maximum. Further switches N, O, P at the loading or unloading positions operate through control 28 to stop or start the motor 26 causing cyclical movement when the load is to be either withdrawn or deposited. The arrangement permits the load to make a limited number of inadvertent engagements with obstructions without being released. The gripper comprises a cylindrical casing 100, Fig. 3, carrying pivoted claws 106 operated by a vertically reciprocal cam 144 in engagement with rollers 137, 138. The cam 144 is actuated through a lost-motion collar 42 by a rod 102 attached to the lifting cable 3 carrying a weighted cam member 110 having stepped grooves 118 engaged by a pin 120 on the cylindrical casing 100. The weight 110 is free to reciprocate vertically when the load in the cable 3 is applied and released and the pin 120 and groove 78 arrangement causing the weight 110 to rotate stepwise. In one group of four rotatable positions of the weight 110, teeth prevent the weight 110 and rod 102 from being raised sufficiently to release the claws 106 so that the load is retained. In another group of four rotatable positions of the weight 110, the teeth 122 do not engage the weight 110 so that the weight 110 and rod 102 are raised sufficiently for a collar 142 on the rod 102 to engage and raise the cam 144 to release the claws 106.
