Title: Improvements in or relating to scanning display devices
Inventor: SCHAGEN PIETER
IPC: H04N3/02
Filed: 1956-10-04
Abstract: 865,665. Television. MULLARD Ltd. July 1, 1957 [Oct. 4, 1956], No. 30359/56. Class 40(3) In a television receiver successive lines of the picture produced by scanning an elongated phosphor strip P 1  (in an elongated cylindrical cathode-ray tube T), in the line direction only, are imaged by means of the operative one of three moving cylindrical lenses L (supported by a carrier C rotated at one-third frame frequency) to provide the frame-deflection components on to a hyperbolic mirror H. An observer looking at light coming from direction Z thus sees a complete picture, B B<SP>1</SP>. The arrangement of cathode-ray tube T and the carrier C may be similar to that described in Specification 827,851 and the cathode-ray tube itself may be the same as that described in either Specifications 865,663 or 865,666. When colour reproduction is required the tube is provided with three phosphor strips P producing three different component colours and the colour trace produced by applying a "spot-wobble" of either sinusoidal or sawtooth waveform to the (single) electron beam. For reproducing colour signals of the N.T.C.S. type the frequency of the "spot-wobble" is made equal to that of the chrominance subcarrier so that the "I" and "Q" signals are decoded at the electron gun. Alternatively three electron beams may be employed to scan the three phosphor strips. For frame sequential colour display the lenses L may be associated with appropriate colour filters or may themselves be arranged to act as colour filters. When both monochrome and colour operation is required the tube may be provided with a phosphor strip producing the monochrome radiation in addition to the three colour phosphor strips. For stereoscopic operation the lenses L may be polarized in different directions. The rotation of the carrier C may be synchronized with the input signals by varying the saturation of a reactor controlled device which governs the (induction) motor driving the carrier in accordance with variations in phase between the frame synchronizing signals and a sawtooth wave generated by a suitably shaped rotor on the carrier driving shaft. Specification 846,544 also is referred to.

IPC: F02M33/04
Filed: 1923-12-04
Abstract: 230,165. Dodson, E. Dec. 4, 1923. Cylinders, pipes for.-Unvaporized fuel particles on their way from the carburettor to the engine cylinders, are collected and reatomized and returned' to the mixture stream in the throat of a Venturi or like construction at a point in advance of that at which they were separated from such stream. Mixture from a carburettor enters at A<3>, passes through a Venturi or other cinstricted passage B, is discharged into an enlargement A and then passes to the cylinder through passages A<4> out of alignment with the discharge end of the Venturi B. The unvaporized fuel particles which may strike the upper wall of the chamber or may fall due to the. decrease in the velocity and the change in direction of the mixture stream collect in the sump C formed by the Venturi and are re-atomized and returned to the mixture stream by and through a series of orifices B<3> in the throat of the Venturi. The collected fuel may be slightly heated by a jacket D. The Venturi may be replaced by another of different bore, and the passages A<4> may slope upwardly to cause fuel deposited in them to drain back into the sump C. There may be any number of passages A<4> and they are preferably of elliptical section with long axis horizontal so that the top of the pipe may be kept lower with reference to the outlet end of the Venturi B.

Title: Outlet selector valve for tiltable and invertible liquid-filled tank
IPC: B64D37/22
Filed: 1956-10-05
Abstract: 800,915. Emptying tanks. SIMCOCK, W. H. Oct. 5, 1956 [Oct. 7, 1955], No. 30479/56. Class 21. [Also in Group XXIX] A selector valve for a tiltable and invertible liquid fuel tank to ensure that liquid is only drawn from the lowermost part of the tank comprises a housing 1, Fig. 2, having a vertical passage 2 accommodating two balls 5, 6 spaced apart by a liner 7 the ends of which constitute seats 8, 9 for the balls, a rod 10 sliding in a bushing 10 interacting on the balls to prevent simultaneous seating thereof, and a horizontal passage 12 in the housing 1 associated with an identical pair of balls 15, 16. The passages 2, 12 are joined by a bore 22 that opens into passage 2 adjacent the seat 8, and another bore from passage 2 intermediate the balls 5, 6 leads to an outlet 24. Two inlet bores 25, 26 open into passage 12 adjacent the seats of balls 15, 16 respectively, whilst a third inlet 29 is connected to passage 2 near the seat 9. The housing 1 is fixed in an aircraft fuel tank 31, Fig. 1, with conduits 32, 33, 34 connected to the inlets 25, 26, 29, Fig. 2, the free ends of the conduits being arranged adjacent the front, rear and top walls of the tank, respectively, with the ends of conduits 32, 33, Fig. 1, also disposed near to the bottom of the tank. The latter has an outlet 24a attached to the housing outlet 24, Fig. 2, and an inlet 31a, Fig. 1. When the aircraft is straight and level the ball 6 is seated to prevent air entering the passage 2 from the conduit 34, and the ball 5 is unseated, due to gravity, whilst either one of the balls 15, 16 is open to supply fuel to the outlet 24 from either inlet 25, 26 ; upon the aircraft climbing or diving one or the other ball 15, 16 is unseated by gravity and fuel is supplied to the outlet 24 from that one of the two conduits 32, 33 having the lower end. Should the tank be inverted then ball 6 is unseated, ball 5 is seated and liquid enters passage 2 from conduit 34; air is prevented from passing between conduits 32, 33 and passage 2. This arrangement of valves ensures that liquid is only drawn from the lowermost part of the tank. In a modification, the valves may be disposed outside the tank.

Title: Improvements in or relating to subscribers' uniselector circuits
IPC: H04Q3/00
Filed: 1956-10-05
Abstract: 831,983. Automatic exchange systems. GENERAL ELECTRIC CO. Ltd., and WHEATCROFT, L. Oct. 4, 1957 [Oct. 5, 1956], No. 30481/56. Class 40 (4). The stepping circuit of a subscriber's uniselector includes normally closed interrupter contacts, normally open line relay contacts, and normally closed cut-off relay contacts, the cutoff relay responding, over a circuit which includes the interrupter contacts, to one of two voltage conditions encountered by a test wiper of the uniselector. As shown, the stepping magnet DM interacts with the interrupter contacts dm when line relay LR responds to a call. Operation of LR also connects up test wiper DM4 over low resistance winding 8 of cut-off relay K, rectifier 10, and contacts dm to earth. A short-circuit is also put across terminals 4 and 5 to the subscriber's meter. The busy condition of an outlet is earth and the idle condition is negative resistance battery which causes K to respond. Operation of K busies the seized first selector, extends the line forward which releases LR, and locks up to earth returned from the first selector in a circuit including winding 9 and magnet DM which however does not operate. When K falls back on release of the first selector, wiper DM1 provides a homing circuit for the selector which may have a number of home positions.

Title: Improvements relating to transfer mechanism for calculating machines
IPC: G06C15/38
Filed: 1922-11-07
Abstract: 210,866. Odhner, V. J. Nov. 7, 1922. Transfer-mechanism.-In a cam-dise and pin-wheel machine each pin-wheel 3 has two transfer-actuating pins 4 pivoted in it to swing in the plane of the pin-wheel. Each pin 4 has an extension 15 and an arm 13 rigid with it, the part 15 carrying a pin 16 moving in a slot 17 in a member 14 pivoted in the pin-wheel. The normal positions of these parts are shown in full lines and at transfer the usual transfer arm 6 contacts with the arm 13, swinging it into the pin-wheel, whereupon the pin 4 swings out from the pin-wheel and actuates the wheel 7 one step, turning the numeral wheel attached to the wheel 8 one step. At the same time the pin and slot connection 16, 17 causes the arm 14 to swing out from the pin-wheel. After transfer the arm 14 contacts with a surface 12, or with a surface 11 in the reverse direction, on a member 10 rigid with the laterally movable totalizing-counter carriage 5. This, as an addition to the usual spring- restoring means, positively restores the arm 14 and the pin 4 into the pin-wheel into inactive position. In a modification, Fig. 3, the pin on the arm 13 co-operates with a slot in a shutter 18 covering an opening 19 in the pin-wheel for the known interlocking Geneva wheel. When the arm 13 is actuated by the arm 6 to bring the pin 4 to active position the shutter 18 is swung inwardly so that the projection 20 on it is protruded, this part 20 then acting, after transfer, with the surfaces 11 or 12, as in the case of arm 14, Fig. 1, to positively restore the pin 4 to inactive position. The arm 14 shown in Fig. 1 may, if desired, be combined with the shutter 18 shown in Fig. 3.

Abstract: 535,795. Automatic circuit-breakers. GENERAL ELECTRIC CO., Ltd., and KEELEY, F. J. Nov. 22, 1939, No. 30587. [Class 38 (v)] The pivoted operating-handle 2 carries pivotally at 15 a latch 14 which carries a roller 17 normally engaging the end of the closing lever 16 and deflectible by a weighted, unbalanced lever 3 pivoted to the handle at 4, if the handle-speed is too low. The lever 3 is urged in the anti-clockwise tripping direction by a tension spring 5, this force being overcome by the centrifugal force of the lever provided the operating speed is adequate. Movement of the lever 3 in the tripping direction near the ends of the travel, when operating-speed is necessarily slow, is prevented by cams 9, 10 engaging a roller 11 on the lever. The handle is latched closed at 20, 21, and an overload trip 19 is provided.

Abstract: 1,087,517. Control of D.C. motors. RAYMOND CORPORATION. July 8, 1966, No. 30740/66. Heading H2J. A series motor A driving a lift-truck has accelerating contactors A1-A3 which are energized in timed sequence following closure of camoperated switches S3-S5. The timing circuit associated with the contactor A1 comprises integrator network C1, R4, which renders unijunction transistor U1 conductive a predetermined period after closure of switch S3. A pulse is then supplied through capacitor C2, which forms part of a differentiating network, to the gate of rectifier SCR1 which is rendered conductive to energize contactor A1 A capacitor C3 prevents the self-induction of the coil of the contactor from inhibiting firing of the rectifier SCR1. The cathode voltage of the rectifier SCR1 is thus applied through integrating network R8, C4, to transistor U2 which provides a pulse through capacitor C5 to fire rectifier SCR2 provided that switch S4 is closed. The acceleration contactor A2 is energized, followed by energization of contactor A3 if switch S5 is closed. An interlock switch I prevents energization of contactors A2, A3, when a load carriage is too high, these contactors being reclosed automatically when the load is lowered. Alternatively, the interlock contacts may be operated by an over-current relay CR. The unijunction transistors may be replaced by neon bulbs or PNPN diodes.
