Title: Sequential timer suitable for controlling electrical appliances such as washing machines
IPC: H01H43/12
Filed: 1965-10-25
Abstract: 1,059,200. Time switches. MALLORY BATTERIES Ltd. Oct. 25, 1965 [Dec. 3, 1964], No. 45004/65. Heading H2B. [Also in Divisions D1 and G3] A timer for sequentially controlling electrical circuits comprises a cam-shaft 14 intermittently rotated by an escapement (not shown) coupled to a motor 11, switches 18 operated by cams 16 on the shaft 14, and an actuator 23 spring- loaded against a toothed cam 25 on the shaft 14 so as to be movable between a portion in which it holds switch contacts 53, 54 carried by blades 49, 50 in engagement with contacts 51, 52, to close an electrical circuit, and a position in which the contacts 53, 54 are released to open said circuit. The timer may be used for controlling a washing machine to ensure that a drain control circuit is energized to drain the machine before the commencement of a washing operation of pro-selected duration. In such use of the timer a washing programme is initiated by pulling the cam-shaft 14 outwardly so that the cam 25 bears against tabs 47, 48 on blades 49, 50 to engage the contacts 53, 54 with contacts 51, 52 to energize the drain control circuit, and the cam 25 also opens a switch 40 to de-energize the timer motor 11. The shaft 14 is then rotated to select a desired washing interval and so that the actuator 23 lies opposite the toothed part of the cam 25 and the contacts 53, 54, are held in grooves 30, 32 in the actuator 23 in engagement with the contacts 51, 52. By pushing inwardly the shaft 14 the switch 40 is closed to energize the motor 11, and when the cam 25 has rotated by one tooth it coacts with a projection 34 on the member 23 to release the contacts 53, 54 which separate from the contacts 51, 52 to de-energize the drain control circuit.

Abstract: 1324128 Calling systems CHARBONNAGES DE FRANCE 12 Oct 1971 [14 Oct 1970] 47498/71 Heading H4L In a calling system, transmitters E1 to EN operate successively, each being triggered into transmission by a control signal which is generated by the preceding transmitter when it stops transmitting, and which is sent over a wire 6n, means being provided to make the first transmitter E 1 transmit after the last EN has stopped. The control signal from the last transmitter E N  may be fed back over a line 6 1  to trigger E1 to give cyclic operation when a switch 9 is in the position shown, a central call station 7 being arranged to start the first transmission of E1 when switch 9 is in another position. Alternatively, the call station 7 may be connected to E1 and either a switch (8, Fig. 2, not shown) connected in feedback line 6 1  to give cyclic operation, or a succession of start pulses supplied by station 7 (Fig. 1, not shown) with a separation at least equal to the total operation time of all the transmitters. A positive going voltage constitutes the control voltage to a transmitter (Fig. 5, not shown) in which it turns on a transistor (T2); this turns off another transistor (T3) whose output is differentiated (CR) and the positive part used to trigger a monostable (T4, T5) which turns on further transistors (T6, T1) to earth one side of the oscillator (1n) so that the latter draws power (from 3n) and energizes the output of the transmitter. When the monostable period ends, the final transistor (T1) is turned off to de-energize the transmitter and to generate (at 6 n + 1 ) a positive-going signal to trigger the next transmitter control circuit. Each transmitter may have its own power supply, or may have a current regulator (17, Figs. 7, 8, not shown) and a storage capacitor (18) fed from a common supply (16). The common supply (16), a common earth (12) and the control signal wires (6) may form a multicore cable whose sheath (20) acts as a common aerial.

The bore comprising the internal tooth crests of the sleeve 101 and the peripheral surface of the ring 200 may be cylindrical as shown, or, for enhanced synchronizing effect or engaging thrust, may be slightly tapered in either direction. On final meshing the second ring 125 retainingly engages a sharp-cornered recess A in the sleeve 101. The ring 200 is connected to the member 117 by means providing mechanical servo-enhancement of the synchronic ing frictional engagement and baulking force. As shown, two nested split rings 205, 206 respectively connected to the ring 200 by inclined abutments and to a hub 119 of the member 117 have their split ends inclined to co-operate with a trapezoidal block (209). In Fig. 3 (not shown), the ring 200 is connected to the hub 119 by a single split ring (250) having arcuate branches which may be hooked directly into slots (252) in the hub or engage an arcuate strip engaging the hub, and, for differing upshift and downshift servoenhancement, may be of differing lengths. Each ring of the servo mechanism may be negatively or positively pre-stressed. The ring 200 and the inner ends of the teeth 108 may have rounded or tapered lead-in surfaces. The ring 125 is axially shiftable in a seat 202 so as to allow its spontaneous expansion, and for even wear of the rubbing surfaces of the device the ring 125 has its left hand portion extended and is made of softer material.
