Filed: 1962-08-22
Abstract: 946,375. Electric selective signalling systems; burglar alarms. RAD-O-LITE Inc. Aug. 22,1962, No. 32233/62. Headings G4H and G4N. The lights in a building (e.g. shop or factory) can be turned on from a remote point, (e.g. a patrolling police car) by means of an audio frequency signal modulated on a r.f. carrier, and, if desired, the receiver in the building can be linked to a burglar alarm system so that in the event of an alarm being given the lights in the building are also turned on. Transmitter. The transmitter comprises a crystal controlled r.f. oscillator 1, Fig. 1, modulated by the output of a 115 c/s audio frequency oscillator 33, 28, and feeding a tuned aerial 6, 7. A switch 19 permits the carrier frequency to be changed so that other equipment may also be controlled. A modified transmitter, suitable for use by a night watchman (Fig. 5, not shown) is described using a neon oscillator for the audio frequency signal. Receiver (Fig 2). The receiver in the building includes a thyratron 57, Fig. 2, which controls a relay which in turn controls the lights, the thyratron being so biased, via a resistor 59 (the points A and B being normally joined by a very low impedance) that it only conducts in the presence of a received audio frequency modified signal. The thyratron is also coupled to the A. C. mains supply which effects its resetting. Burglar alarm. The receiver in the building is such that if the bias on the thyratron is removed the thyratron will conduct. Thus by arranging that the connection between points A and B is broken by a burglar it follows that the lights will be turned on when a burglar is detected.

Filed: 1975-08-07
Abstract: 1512667 Photo-electric barriers ERWIN SICK GmbH OPTIK-ELEKTRONIK 7 Aug 1975 [24 Oct 1974] 33026/75 Heading G1A A light barrier system comprises: a pulsed light source; a detector arranged to receive light from the source over a predetermined path; signal means responsive when the detector senses the interruption of light; and a power unit supplying the source, detector and signal means and comprising substantially only a transformerless rectifier arrangement directly connectable to an electric supply. Pulsed light from a GaAs diode (26,) Fig. 1. (not shown) collimated by a lens (37) is returned along its own path (52) by a retro-reflector (38) and directed by a semi-reflective splitter (39) to a photo-detector (28) for the detection of objects obstructing the path (52). The apparatus Fig. 3, receives power from a unit 49 comprising a transformerless rectifier arrangement 45 with optional smoothing 44 and RF suppression 46, 47, 48. The source 26 is pulsed by the periodic discharge of a first capacitor 22 (0À2-0À8ÁF) through a first thyristor 25 triggered when the capacitor 22, charging through a first charging resistor 21 (30-80 k#) attains a voltage (25-35V) sufficient to turn on a diac 27 connected to the thyristor trigger 33. The pulse ceases, and charging recommences, when the discharge current falls below the holding current of the thyristor 25. An inductor 23 in series with the capacitor 22 limits the discharge current and lengthens the pulse. The photo-detector 28 provides a pulsed signal to an amplifier 29 powered by the p.d. across a regulating diode 24 in series with the first charging resistor 21 and pulse generator 30. Pulses from the amplifier 29 periodically trigger a second thyristor 12 to discharge a second capacitor 15 charged through a second charging resistor 11. A further resistor 16 carrying charging current, and a forwardbiased diode 13 in series with the regulator 24, provide the thyristor 12 with suitable trigger and cathode bias to ensure clean switching. Failure of pulses 50, due to interruption of the light beam, allows the capacitor 15 to continue charging unchecked until it turns on transistors 19, 43 to energize an alarm relay 42 and lamp 17.

Title: Clamp circuit for bootstrap field effect transistor
IPC: H03K19/094
Filed: 1972-07-14
Abstract: 1358010 F.E.T. Boot strap circuits NORTH AMERICAN ROCKWELL CORP 14 July 1972 [22 Dec 1971] 33126/72 Heading H3T To prevent a F.E.T. 26 from conducting in the reverse direction from supply 21 to output 2 when a voltage fed back through C23 from a control circuit 7 tends to make gate 25 of F.E.T. 26 more negative than -V, a clamping F.E.T. 19 is arranged to clamp its gate 25. F.E.T. 19 clamps gate 25 at a voltage more negative than - V by an amount which is less than its threshold, this being ensured by selecting the threshold of F.E.T. 19 to be less than that of F.E.T. 26. When the input at 4 holds F.E.T.'s 17 and 10 on, F.E.T. 12 will be off and F.E.T. 14 on, so that both plates of C8 will be earthed, while C23 is charged through F.E.T. 28. When the input changes, F.E.T. 17 goes off to allow the side 2 of C8 to begin charging toward -V through F.E.T. 26, which is held on by capacitor 23. When the output 6 becomes sufficiently negative due to increasing conduction of F.E.T. 9 in response to the negative-going potential at 2, F.E.T. 12 turns on and F.E.T. 14 off. Point 16 is carried to -V by the bootstrap circuit F.E.T. 15, and point 2 is carried more negative than - V in order to turn F.E.T. 9 full on and overcome its threshold drop, to produce -V at the output 6. The clamping F.E.T. 19 prevents F.E.T. 26 from conducting reversely to discharge C8 during the final part of its voltage swing.

Abstract: 795,979. Sole trimming machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Nov. 19, 1956 [Nov. 19, 1955], No. 33160/55. Addition to 779,459. Class 17(1) Means for adjusting the work support 18 to and from the work feed member, and means for adjusting the yielding means 78 which urge the work support towards the work feeding member, are incorporated in the machine of the parent Specification. Thus the machine may readily be adapted to operate on soles of widely different thickness or of different materials. The support 18 is adjustable forwardly and rearwardly on carrier 24 pivotable about 26 on block 28 to accommodate different thicknesses of work, block 28 being slidable in a guideway, on support 30, concentric with the upper edge of support 18, so that the support is brought into complete contact with the sole as a result of pressure therebetween. Support 18 is normally held erect by engagement of a spring pressed ball on block 28 with a recess in support 30. Turning of handwheel 92 rotates sleeve 72 with worm 70, which rotates with but is slidable lengthwise of the sleeve, and via 68, 62, 56, 54, and 52, moves carrier 24 and so adjusts the support 18 relatively to the feeding member. By turning arm 96, rod 84 is rotated and, by means of screw 86, moves abutment 80 lengthwise, and so varies the compression of spring 78 which via worm 70 &c. urges support 18 towards the feeding member. Arm 96 may be coupled to wheel 92, by engagement of spring detent 98 in one of a series of holes 100 in the wheel, so that sleeve 72 and rod 84 may be rotated together, but, by disengaging detent 98, either the rod or the sleeve may be rotated relatively to the other. The yielding action of support 18 may also be varied by adjusting the distance between the left hand end of the support and notch 102 in arm 52, i.e. when the sole is of yielding nature the setting is such that the end of the support does not engage arm 52, but if the sole material is hard the end of the support is seated in notch 102. An auxiliary rest 20 below support 18 is adjusted so as to ensure that the shoe, when seated on rests 20 and 18, is presented to the knife at the correct angle. Supports 18 and 20 are retracted, for presentation of a shoe, by depression of a treadle (not shown) which acts via mechanism (not shown) to move forwardly plunger 108 which moves block 106, the latter, via arm 103, retracting the carrier of rest 20 and via a lug 50 retracting support 18. Specification 695,467 also is referred to.
