Title: Actuator assemblies for electric switches
IPC: H01H23/28
Filed: 1970-12-01
Abstract: 1326400 Mechanical switches ILLINOIS TOOL WORKS Inc 1 Dec 1970 [1 Dec 1969] 57092/70 Heading H1N An actuator assembly for simultaneously operating a plurality of switches 22, 24 by a single pivoted operating lever 16, comprises a rocking actuator member 30 having a portion 32, 34 selectively movable into operative engagement with one or more of the switches by movement of the lever 16, wherein the lever 16 carries a roller 58 biased towards one or more rod members (such as 52b or 52d) mounted on the actuator 30 parallel to the axis of the roller 58, to move the actuator 30 by selective transference of the biasing force from one place on the, or a, rod member to another place on the, or another, rod member as lever 16 is moved. As shown, the actuator 30 comprises two side walls 48 and a base portion providing noses 32, 34, and is pivoted at 28. Five pairs of aligned holes, 50a to 50e, in the walls 48 may receive rod members according to the desired type of switch action. As shown in Fig. 1 a rod 52c carrying a roller 54 is provided in the central pair of holes 50c and the lever 16 has two positions only, the switches 22 being retained operated in one position and switches 24 in the other. If the rod 52c and its roller 54 are omitted the lever 16 has a central neutral position (Fig. 5, not shown). If a pair of rods carrying a metal band (72a, Figs. 3 and 4, not shown) are inserted in holes 50a and 50b (or in holes 50d and 50e) the roller 58 does not go overcentre and the action of lever 16 is retractive. Thus twoway retraction (Fig. 3, not shown) may be provided, or a combination of retraction one side and maintained set the other side may be provided (Fig. 4, not shown). Portions of actuator 30 may engage the switch plungers 22<SP>1</SP>, 241 directly as in Fig. 4 (not shown) but preferably the noses 32, 34 act on springs 38, 40 secured to rods 42, 44 whereby a plurality of switches 22, 24 may be operated over a wider range of manufacturing tolerances. The rods 42, 44 may extend beyond the side walls of housing 12 to operate switches mounted exteriorly thereof (Fig. 2, not shown). As shown, two rollers 58 on an axle 60 are carried by lever 16, but to avoid the possibility of the lever 16 being stable in an intermediate position if the axes of rollers 58 and a rod 52b (or the like) are not strictly parallel, a unitary roller construction (58<SP>1</SP>, Fig. 7, not shown) may be provided.

Abstract: 1,272,859. Fluid servo-control systems. H.M. HOBSON Ltd. Nov.20, 1970 [Nov. 25, 1969], No.57677/69. Heading G3P. A relay spool 10 controlling servomotor 12 is controlled by two pairs of jet tubes A1, B1 and A2, B2 actuated by torque motors 15, 17 receiving normally identical signals from respective comparators 19 in control channels TA1-TB2. Any differences in the output signals from the pairs of jet tubes are detected by respective pistons 21, 23 which apply negative feedback to jet tubes A1, A2 via springs 22, 24. Movement of pistons 21, 23 is arrested when the pistons uncover exhaust port 26, at which point lever 30, 32 disengages micro-switch 29 to operate indicator 27. Introduction of a deadband by opposing null shift of the two pairs of jet tubes is avoided by giving pair A2, B2 force authority over pair A1, B1, this being achieved by providing larger effective areas on spool 10 for A2, B2 than for A1, B1. Springs such as 25 apply negative feedback to the jet tubes from spool 10.

Patent GB-666010-A (GB)
Abstract: 666,010. Radio navigation. DECCA RECORD CO., Ltd., and POWELL, C. July 3, 1950 [July 1, 1949], No. 17509/49. Class 40 (vii). The invention relates to radio navigation systems of the type in which positional indications are obtained at a receiver by the phase comparison of received radio signals of different frequencies which are radiated in fixed multiple phase relationship from spaced transmitters. A system of this type is described in Specification 620,479. In such systems it is found that, if the receiver aerial is placed close to a tree or similar large object as may be required in survey work, the measured phase angles correspond to erroneous position indications. According to the invention means are provided for continuously radiating two signals of different frequencies in fixed multiple phase relationship from a single transmitter and these signals are received and compared in phase at the receiver. Under normal conditions their phase relation will be constant and may be regarded as zero but near a tree or similar object it will differ from the zero value and, from the difference, corrections for all the phase determinations made at the same point may be obtained. If it is assumed that equal phase shifts in all the signals are caused by the object then the error is due to the different factors by which the signals are multiplied in the receiver and from a knowledge of one error value the others can be derived. In one embodiment of the invention signals of the fifth and sixth harmonics of a fundamental frequency are radiated continuously from one station in fixed multiple phase relationship and signals of the eighth and ninth harmonics of the same fundamental and synchronized with these master signals are radiated respectively from two spaced slave stations, Figs. 1a, 1b, 1c (not shown). At the receiver the signals are received on antenna 34 and separated by filters 30, 31, 32, and 33 tuned respectively to the sixth, eighth, ninth and fifth harmonic signals. The outputs of filters 30 and 31 are multiplied to a common comparison frequency (the twenty-fourth harmonic) and compared in phase in discriminator 35 to give a positional indication at 36. Similarly the outputs of filters 30 and 32 compared in phase at the eighteenth harmonic frequency give a second positional indication at 38. The outputs from filters 30 and 33, that is the two signals from the master station, are compared in phase at the thirtieth harmonic frequency in discriminator 39 and normally give zero indication on meter 40 except when it is necessary to apply a correction to the indications at 36 and 38. Specification 620,481 also is referred to.
