Title: Improvements relating to mercury switches
IPC: H01H29/18
Filed: 1937-02-24
Abstract: 490,946. Mercury switches. CIANCHI, A. Feb. 24, 1937, Nos. 5597 and 19150. [Class 38 (v)] Energization of a coil 6 depresses plunger 4 to force mercury past a ball valve 7 to flow over the edge of vessel 3 into vessel 2 to complete a circuit between electrodes 8, 9. Energization of a coil 10 surrounding electrode 9 which is magnetic, draws valve 7 downwards to allow the mercury to return and break the circuit. Instead of having an outer vessel 2, the contact 8 may be arranged ina side limb of vessel 3. In a modification the plunger can be held in the depressed position by an external permanent magnet and released either by removing the magnet or by applying an opposing electromagnetic field. A changeover switch is described, in which a third electrode dips down inside the plunger which is provided with a valve in the manner described in Specification 453,229. Instead of releasing the valve by means of a solenoid, a time delay can be introduced by providing a small opening adjacent to or in the seating of the valve. The time delay may be varied by tilting the base on which the switch is mounted.

Title: Improvements in or relating to wireless direction finding, bearing finding, and similar systems
IPC: G01S1/68
Filed: 1932-02-25
Abstract: 397,524. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London, SMITH, S. B., Gordonville, Roxwell Road, Chelmsford, and ECKERSLEY, T. L., Weatheroak, Danbury, both in Essex. Feb. 25, 1932, No. 5691. [Class 40 (v).] Night-effect and similar arrors in direction-finding are eliminated by means which cut-out from the receiver any "repeated" signal impulses due to space waves reflected from the Heaviside laver. The normal interval between the primary or direct-wave signal and its repetition by the space wave is taken to be 0À00015 second. An interrupter at the transmitter is timed to radiate signal pulses lasting 0À00015 second at intervals of 0À01 second. At the receiver, Fig. 2, which may be on an aeroplane, the frame aerial L is connected intermittently to the receiver through an interrupter C1, driven synchronously with that at the transmitter. The signal impulses are fed through brushes B1, B2 to a "flash light-valve carried by a rotating disc RD and then pass to the phones RT. If transmission is interrupted and the primary signal is followed by two space-wave repeats, the tube V would show them stroboscopically at 1, 2, 3, Fig. 4. By synchronizing the interrupters and adjusting the position of the brushes B1, B2, the "repeat" signals corresponding to 2, 3 can be cut out. The critical maximum or minimum position is then ascertained on the first or " direct " wave which is free from polarization error.

Title: Aircraft having rotative sustaining blades and control mechanism for such aircraft
IPC: B64C1/00
Filed: 1948-02-26
Abstract: 644,504. Multi-rotor helicopters. AUTOGIRO CO. OF AMERICA. Feb. 26, 1948 No. 5732. Convention date, Nov. 22, 1946. [Class 4] In a rotary wing aircraft having two main sustaining rotors side-by-side and a third auxiliary rotor on the longitudinal centre line of the aircraft and spaced horizontally from the line joining the centres of the main rotors, control in roll is obtained by differential collective pitch control of the main rotors, control in pitch by collective pitch control of the auxiliary rotor alone, and control in yaw by varying the inclination in the rolling plane of the aircraft of the lift vector of the auxiliary rotor. In the form shown, to control the lift, simultaneous increase or decrease of collective pitch is applied to the forward motors 8, 9 by a control lever 38 acting through cables 39, 40, and screw jacks 32, 32a respectively. For lateral control, the equal and opposite collective pitch variations are applied to the forward rotors by transverse movement of a control column 34 operating jacks 24, 24a through cables 37. The pitching attitude of the aircraft is controlled by the mean pitch setting of the rear auxiliary rotor 10, the swash-plate 45 of which is operated by fore-and-aft movement of the column 34 acting through cables 52, a bellcrank 51 and links 49, 48. Control in yaw is effected by tilting the lift line of the rear rotor, cyclic pitch variation being applied to the blades by a bell-crank 58 and links 57, 55, 54, 53, connected to the rudder bar 60 by cables 59. In order that such tilting of the lift line shall not materially reduce the effective lift of the rear rotor, the mean collective pitch setting of the blades is increased automatically by a bellcrank 64 connected to the member 55 of the cyclic pitch control linkage and actuating the link 48 of the collective pitch control mechanism.

Title: Improvements in or relating to radio receivers provided with time switch control devices
IPC: G04C23/00
Filed: 1954-03-02
Abstract: 752,910. Radio receiving apparatus TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. March 2, 1954 [March 2, 1953], No. 6041/54. Class 40 (5). In a radio receiver comprising a loud-speaker, there is provided a time-switch which is adapted to switch the receiver on at a predetermined time and is adapted to direct, after a predetermined interval, alarm signals to the loudspeaker, over-riding manual control means being also provided which is adapted to prevent the transmission of the alarm signals to the loudspeaker. A shaft rotating continuously at the rate of once every 12 hours carries discs 1 and 2 each having a notch therein. At a predetermined time, determined by the position of disc 1, the switch 4 closes thus switching the receiver on. After a further predetermined interval, which may be adjustable, the switch S operates due to the spring-urged plunger St entering into the notch 3 in disc 2. In the arrangement shown the grid of the output valve R feeding the loud-speaker (not shown) is normally connected via the switch S to the volume control resistor P; when however the switch S operates the full signal voltage, providing an alarm signal, is applied to the valve R. The switch S may be prevented from operating or restored to its original position after operation by depressing a push button 5. The button is held in its depressed position until released by further means (not shown) which may comprise means operated by the disc 1 after the notch 3 has passed the position in which the plunger St can engage therewith. In a first modification, Fig. 2 (not shown), operation of switch S causes a mainsvoltage signal to be applied to the grid of the output valve. Fig. 3 (not shown) shows a twovalve output stage having negative feedback to the first valve. Operation of the switch S causes the feedback voltage to be applied to the second valve, so that the feedback now becomes positive and causes the second valve to oscillate and thus apply an alarm signal to the loudspeaker. The switch S may alternatively be arranged to reverse the sign of the feedback voltage to the first valve. In a final modification, Fig. 5 (not shown), the switch S controls a vibrator energized from the heater supply voltage, the voltage pulses derived from the vibrator being applied to the grid of the output valve.
