Title: Improvements in and relating to television
IPC: H04N3/08
Filed: 1923-11-16
Abstract: 209,049. BÚlin, E. Dec. 27, 1922, [Convention date]. Television apparatus; copying telegraphs.- Relates to transmitting and receiving apparatus for wireless television. At the transmitting station light from successive elemental areas of the image to be 'transmitted is directed on to a stationary light-sensitive cell either by the use of two mirrors oscillating at definite relative periods about mutually perpendicular axes or by an oscillograph mirror and an apertured diaphragm moving in definite relation to the oscillations of the mirror. Fig. 1 shows one transmitting arrangement. The real image formed at A, B is reflected by a mirror M<1> on to a diaphragm A<1>, B' formed with a small hole behind which is disposed at S the light-sensitive cell with or without an interposed optical system. The mirror M<1> oscillates continuously about its axis m<1>, and each oscillation serves to bring successively all points in a line on the image to the point S. A mirror M<2> is interposed in the reflected beam, and at each reversal of movement of the mirror M<1> is turned about its axis m<2> sufficiently to bring images of points in a succeeding line to the point S. In the alternative arrangement the oscillograph is supplied with alternating current to oscillate its mirror at a predetermined frequency, and the apertured diaphragm is given a movement of translation parallel to the plane of oscillation of the image produced by the mirror and a system of lenses. At the receiving station the current deflects a mirror R, Fig. 3, in accordance with the degree of modulation and this mirror reflects light from a source E on to a strip T formed with graduated transparency which increases in accordance with increase of illumination of the point S at the transmitting station. A lens L<1> brings the reflected beam to a focus at E<1> and a lens L<2> positions the image on a screen E after reflection from a mirror R<1> oscillated synchronously with the mirror M', Fig. 1, and a mirror R<2> oscillated synchronously with the mirror M<2>, Fig. 1, about an axis at right angles to the axis of the mirror R'. Alternatively a mirror, placed at the focus E<1>, is 'deflected equally with but oppositely to the deflections of the mirror R and the resulting fixed beam is deflected by a mirror system similar to the system R<1>, R<2>, Fig. 3. The received current may be used to deflect a cathode ray in a Braun tube in relation to a lead or like screen of varying thickness or capacity, or the Kerr phenomenon may be utilized. Reference has been directed by the Comptroller to Specification 14503/11.

Abstract: 1291154 Proximity switches W R URMENYI 27 April 1971 [17 June 1970] 29271/70 Heading G1N [Also in Division G4] A capacitance proximity switch comprises a squarewave oscillator 1 ... 3 feeding a pulse stretcher 5 ... 10 including a capacitance 6 and means (12 ... 16) responsive to the mark-space ratio of the stretched pulses. As described, the squarewave oscillator comprises a Schmitt trigger 1 having a feedback loop including resistor 2 and capacitor 3 and is arranged to turn on transistor 5 during each positive half cycle so as to discharge capacitance 6. Capacitance 6 recharges during each negative half cycle via resistor 28 and transistor 27. The circuit is adjusted so that, in the absence of a body adjacent capacitance 6, transistor 8 and Schmitt trigger 10 will be turned on during each negative half cycle so as to maintain transistor 16 conductive and relay 15 energized. Proximity of a body to capacitance 6 prevents transistors 12, 16 being conductive and releases relay 15. A feedback path via transistor 23, time delay 25, 26 and transistor 27 prevents operation by slow changes in capacitance 6 or in the circuit parameters. Capacitance 6 may be part of an insulated safe or part of a window-protecting grill. Alternatively capacitance 6 may be used for counting splices in paper. In Fig. 1 (not shown) the feedback path 23 ... 28 is omitted and capacitor 22 is connected across the collector load of transistor 12.

Abstract: 703,553. Weighing-apparatus. AVERY, Ltd., W. & T. March 3, 1952 [Dec. 2, 1950],. No. 29537/50. Class 143 [Also in Groups XXX and XXXV] Constant rate of feed of powdered, granular, or like materials from a bulk supply is maintained by an apparatus comprising a hopper disposed above a first belt conveyer and arranged to feed it through an adjustable gate or baffle, the first conveyer discharging on to a second belt conveyer supported on a weigh beam the movement of which operates contacts for electrically controlling the gate or baffle. As shown, the hopper 1. Fig. 1A feeds the first conveyer 2 through a vertically-sliding gate 4, and the conveyer 2 discharges through a shoot 5 on to the main conveyer 6, which is driven at constant speed and is suspended by links 8 from a pair of levers 9, Figs. 1 and 1A. The levers 9 hang by :a link 10 from the weigh beam 11 which carries balance weights 12, 12a, 12b and a dashpot 13a at the opposite side of its fulcrum, and is connected at 13 to " over " and " under " weight indicator 14 associated with electric contacts of the kind described in Specification 662,455. If the layer of material on the belt 6 is too thin, its reduced weight causes one of the contacts to close and to start the motor 15 which operates through screw-and nut gear 16 in such direction that the gate 4 is raised by one stage to allow rapid feed. If the layer is too thick, the motor operates in reverse direction. After one operation of the motor, a further operation is prevented until the upper run of the conveyer has traversed its own length. This is effected by an internal switch one contact of which is driven by a chain 6a, and therefore moves synchronously with the conveyer. The internal switch is shunted by a manual switch to permit rapid adjustment of the. gate 4. The Specification includes a diagram of the electric control circuits, Fig. 2 (not shown).
