Patent GB-383966-A (GB)
Title: Improvements in or relating to the distant control of electric circuits
IPC: G08C19/16
Filed: 1931-06-01
Abstract: 383,966. Remote control of motors. JONES, A. E.. 21, Kelso Road, Leeds. June 1, 1931, No. 15924. [Class 38 (iii).] A motor H operates an interrupter in circuit with police &c. lamp signals and is started or stopped by impulses sent over a control circuit B, an indication being given at the control station that the motor has started or stopped. Momentary depression of key A sends an alternating current through the circuit B causing actuation of a relay P and of a ratchet device F, thereby causing the motor H to start. As the motor accelerates, a centrifugal device driven thereby sequentially opens contacts a, b, closes b, d, and opens c, d. When contacts a, bare closed a relay N is energized over the circuit B in series with an indicating relay at the control station, and the relay N maintains its circuit independently of the opening of the contacts c, d until a key AA is momentarily opened. A subsequent depression of the key A causes a further operation of the ratchet device F and stopping of the motor. The contacts a .. d operate in the reverse order. When contacts c, d close relay N and the indicating relay are energized, and when contacts a, b close, relay N is short-circuited so that its armature falls away and opens circuit B, thus the indication is cancelled without it being necessary to depress the key AA. The centrifugal device may also operate contacts in circuit with the interrupter. The circuit B is available for telephonic purposes when the motor is not being controlled.

IPC: B21D7/12
Filed: 1969-11-20
Abstract: 1287870 Angular bending C U PEDDING- HAUS 20 Nov 1969 [23 Nov 1968] 16057/72 Divided out of 1286865 Heading B3E [Also in Division G3] Reverse elastic travel of a bar, which has been bent to a predetermined angle by a rotatable platen having a pair of bending tools coacting with a stationary bending tool, is compensated for by continuing the bending through a supplementary angle which is determined by measurement of the current consumption of an electric motor driving the platen in the elastic deformation range of the bar being bent. In the embodiment shown in Fig. 3 the platen motor 28 is coupled to a control motor 36 by an electromagnetic clutch 35. During the bending of the bar a wiper 38 copies the traversed angle of rotation of the motor 36 on a slipring 39. The wiper 38 is stopped when the circuit of the clutch 35 is interrupted after the excitation of a relay 33 due to current consumption of the motor 28 reaching a preset value. Simultaneously a limit switch 41 is actuated to connect the motor 36 to a voltage source 34 and so cause the wiper 38 to reverse upon the slipring 39. A relay 27 will thus remain activated and so maintain the motor 28 switched on for the duration of the return run of the motor 36. In the embodiment shown in Fig. 4 a capacitor 45 is charged with respect to time until a preset current flow is reached at which time a contact 44 opens. When the predetermined angle is reached a limit switch 41 is operated to discharge the capacitor 45. A relay 50 corresponds to the operating resistance of a transistor 48 and provided sufficient current flows maintains the contact 51 for the circuit of the relay 27 in the closed position.
