Patent GB-1374594-A (GB)
Title: Proximity switch
IPC: H03K17/95
Filed: 1971-11-01
Abstract: 1374594 Proximity switches G WEBER 1 Nov 1971 [30 Oct 1970] 50753/71 Heading G1N In a proximity switch provided with a control circuit for maintaining the output of the switch at a constant level to mitigate against drift and which includes a delay circuit, switching means are provided to alter the time delay. In the absence of body 1 oscillator 2 provides an output and any departure of the output amplitude from a reference value S due to ambient changes, e.g. temperature, causes control circuit 4 to influence the oscillator to restore its amplitude after a time determined by delay 8 or 8', delay 8' being longer than delay 8. If the body 1 is normally absent for longer periods of time that it is present the shorter delay 8 is connected into the control circuit by switch 7. When the body 1 approaches the oscillator 2 at a rate greater than the time delay of 8 the oscillator output is damped and monostable circuit 10 is switched to provide a switching signal at 5. The switching signal at 5 operates to change over the switch 7 to connect the longer delay 8 into the control circuit so that the latter is thus disconnected and the oscillator output cannot return to its initial level. When the body 1 moves away, before the time delay 8' has expired the output returns to its initial level and can be detected using a Schmitt trigger. If the body 1 is normally present and is absent for only short periods then the shorter delay 8 is normally connected in the control circuit and the switch 7 connects the longer delay circuit 8' when the body 1 moves away, so that the control circuit 4 is ineffective during the absence of the body 1. The output of the monostable circuit may be connected to a store Fig. 2 (not shown), so that presence or absence of the body 1 is indicated and stored. The switching signal at 5 may be blocked off for a short period when the supply is first switched on to prevent false indication.

[Also in Division F2] Cam surfaces (76a) (Figs. 1 and 3, not shown), mounted on a programming drum (34) act alternately with similar cam surfaces on a second drum (36) through followers (40, 42), a cranked lever (20) and rack-and-pinion means (26, 24) to feed successive tools (86) mounted on a lathe turret (84) to a workpiece (84b), each drum being arranged to rotate rapidly through a small angle at the end of a feed stroke to allow the cam follower to clear the cam surface quickly and thereby allow rapid return of the slide (28) and turret (84) under the action of a return spring (27). The cams consist of curved members (76) having elongated slots (82) by which they are adjustably bolted to a series of parallel T-section grooves in the drum walls. In a modification (Figs. 6 and 7, not shown) the two programming drums are replaced by two groups of three cam discs mounted on two coaxial shafts. Cams of one or the other group operate in alternation through followers (130) on cranked levers (128) which bear adjustably on a common pivoted carrier member (100) having a pinion (104) in mesh with the feed rack (106) of the turret slide. In both embodiments normal drive of the drum or cam-shafts is effected through coaxial worm gears in mesh with worms which are slidably mounted on their respective driveshafts. Rapid rotation of the drum or camshafts is brought about by imparting sliding movement to the worm on its drive shaft by means of a fluid pressure cylinder and piston acting at the appropriate point in the cycle (Figs. 5 and 8-10, not shown). In a modified drive arrangement (Figs. 11 and 12, not shown), the cam-shafts are driven through spur gears, one gear in the train having a circumferentially extended keyway to accommodate the superimposed rapid movement through a small angle. An annular gear mounted around the hub of one of the spur gears transmits drive thereto by a one-way drive clutch and is itself driven by a rack forming the end of a piston of a fluid-pressure cylinder.
