Abstract: 1,064,981. Transistor relay circuits. WALLACE DAVIDSON & PARTNERS Ltd. Jan. 14, 1964 [Aug. 21, 1963], No. 33175/63. Heading H3T. [Also in Division G1] A transistor oscillator is switched on and off to control a relay 25 in accordance with the level of illumination detected by a photoresistor 20. The oscillator comprises the transistor 15 with a tuned collector circuit coupled to the base circuit. The photoresistor 20 forms a potential divider with resistor 21 and by governing the base potential of transistor 15 switches the oscillator on and off. Output is tapped from the collector circuit and rectified to operate relay 25, and the output is fed back to the base circuit so that the negative potential on the base to switch the oscillator off is greater than that needed to switch it on. On the verge of switching, the oscillator may squeg without releasing or making the contacts of relay 25 but allowing the relay to function without hysteresis. The photo-sensitive element 20 may be replaced by a resistor while the illumination is monitored by a photo-transistor employed in place of transistor 15.

Abstract: 489,832. Retractive switches. TUGWOOD, R. J. (Hetherington, R.) Dec. 8, 1937, No. 33990. [Class 38 (v)] A switch suitable for a cloth guiding machine as described in Specification 489,315, [Group XXXV], is operated by a spring retracted longitudinally movable plunger 41, which carries one of a pair of contact carriers 44, 47 each of which has a plurality of contacts 46, 48, external connection being made by conductors 39, 40. Fig. 2 shows a normally closed switch comprising a cylinder 30 with ends enclosed by caps 31 and 32, through which passes the plunger 41 comprising insulating parts 42, 43 holding between them by a screw 45, a conducting contact carrier 44 studded with conducting pins 46. A spring 49 presses these pins 46 into contact with conducting pins 48 on another fixed contact carrier 47, separation of the contacts being effected by the linear movement of a part of the machine to which the switch is adjustably fixed by a strap 22. To clean the contacts, they may be rubbed together by angular oscillation of the plunger, several methods of limiting this angular movement being described. Other modifications described include a two-way switch and a normally open switch, the plungers being provided with a lost motion device, and also the switch shown in Fig. 12 wherein the plunger 100 is actuated as shown in Fig. 14, at one end by an armature 97 of a solenoid 98 through a lost motion pin- and-slot device 103, 104, and at the other end by an arm 119 of a crank moved by a pivoted feeler arm 122 engaged by the edge of a travelling web 87. The plunger 100 comprises two insulating ends 109. 111, joined by a resistance portion 110 which carries the movable contact carrier 105. The solenoid is first energized from a source 116 through the switch which is opened by the upwardly moving armature 97, electrical connection now being made through the resistance 110, which reduces the current to a value just sufficient to hold up the armature 97, which, through a cam 93 holds a roller 85 in contact with the cloth 87. When the cloth edge moves, it actuates the lever 122 and the crank 121, 119 which further raises the plunger 110 to bring the resistance 110 out of contact with the fixed contact carrier 106 ; the solenoid circuit is then broken and the armature 97 falls. The armature remains down until the cloth edge moves back sufficiently to allow contacts 46 and 48 to re-engage. A further modification is described wherein the resistance is external to the switch.
