Title: Radio navigational system
IPC: G01S13/91
Filed: 1944-12-20
Abstract: 590,620. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. Dec. 20, 1944, No. 25592. Convention date, Sept. 6, 1943. [Clase 40 (v)] In a radio guiding system an energy pulse transmitted from a moving craft causes a radio beacon to' operate and transmit energy pulses successively in two pathdefining patterns. In the system shown in which the equipment indicated at 10 is carried on the moving craft, an impulse source 20 is connected to transmitter 21. which transmits short pulses of energy and also to a blocking circuit 23 serving to block receiver 24 during transmission. The time base 22 of the cathode ray indicator 25 is also synchronized from the impulse source. The transmitted pulses are received at the beacon by antenna 11 and receiver 30 which rectifies the pulse to produce a D.C. impulse which is successively delayed by networks 40 and 41. After delay by network 40 the pulse is applied to relay 42 which operates switches, as shown, to connect aerials 45, 46 and 47, to a, source 44 to transmit a short pulse PA with a radiation pattern such as 16. Relay 42 is released at the end of the pulse and after further delay caused by network 41 relay 43 operates to provide a radiated pulse .PB with a pattern such as 15. Patterns 15 and 16 serve to define an equisignal path. Receiver 24 on the craft receives energy pulses PA and PB successively and their amplitudes IA and IB are compared on indicator 25 showing any deviation from course. An equisignal glide path system for aircraft using further delay networks 50 and 51, relays 52 and 53 and the common source 44 may also be provided, producing glide path' indications IC and ID on the trace. The distance of the craft from the beacon is indicated by the position of IA on the trace, a fixed correction factor being required for the delay in the network 40. If one frequency only is used the ground reflection of a pulse transmitted from an aircraft will be received by receiver 24 and will give a mark on the indicator showing the height of the aircraft. A blocking device 48 is provided at the beacon to prevent reception of its own signals. Specification 588,242 is referred to.

Title: Improvements in or relating to the cathodes of vacuum tubes
IPC: H01J1/14
Filed: 1930-09-03
Abstract: 364,583. Thermionic cathodes; electrodeposition of metals. SOC. DES LAMPES FOTOS, 3, Rue du Midi, Lyons, France. Sept. 3, 1930, No. 26294. Convention date, Sept. 5, 1929. [Class 39 (i).] Cathodes for radio valves, rectifiers, X-ray tubes, &c. and consisting of thermionic substances coated with a thin metallic layer which, when heated, allows electrons to pass through whilst acting as a filter preventing the escape of particles of the substances from the cathode, are made by depositing the layer electrolytically. A layer of platinum, nickel or palladium À001-À01 mm. thick may thus be formed on substances such as caesium, barium, thorium or their compounds or mixtures, the cathode operating at a dull red heat. A tungsten wire 5 with lead-in conductors 8 and with a thick coating 6 of thermionic substances may be electrolytically coated with platinum 7 by using a potential of 2 volts and an aqueous electrolyte containing platinum hydrate and caustic potash in specified proportions, with or without acetic acid to accelerate the deposition. The coating 6 may be barium deposited electrolytically, the wire passing immediately to the platinum bath to prevent oxidation of the barium by the air and not being left in the platinum bath without electrolytic current flowing to prevent attack of the barium by the electrolyte. The coating process described in Specification 308,649, [Class 39 (i), Electric lamps, Arc &c.], may be used. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a cathode consisting of a metal tube filled with emissive material such as oxides of caesium, rubidium, thorium or barium. The tube may be wire-drawn or rolled to reduce its diameter and may have flattened ends secured to wires supplying the heating current. Electron emission may be increased by forming small holes or narrow slots in the tube particularly when the tube contains rubidium or caesium. This subjectmatter does not appear in the Specification as accepted.
Patent GB-444190-A (GB)
Title: Improvements in or relating to electric starter control systems for internal combustion engines
IPC: C09F1/00
Filed: 1934-09-14
Abstract: 444,190. Starting prime movers. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. Sept. 14, 1934, No. 26421. Convention date, Sept. 15, 1933. [Class 38 (iv)] A relay switch for the starting motor of an internal-combustion engine is operated by the return movement after depression of the load clutch pedal, means being provided for maintaining the circuit closed until the engine runs under its own power irrespective of further movement of the pedal. When the switch 11 has been closed, the first part of the return movement of the clutch pedal 3, after it has been depressed to disengage the clutch 2, results in the closing of the switch 7 by which the starting motor SM is placed in circuit with the battery 4. The pedal 3 is connected by a link 19 to a drum 17 having an arcuate contact 21 connected to earth through the winding 16 of the relay switch 7 and the usual engine-driven generator G. Current is conveyed from the battery 4 to the contact 21 either through the spring mounted brush 26 so as to close the switch 16 or through the resistance 23 and brush 22 for holding purposes only. When the pedal 3 is first depressed, the current flowing through brush 22 is not sufficient to operate relay switch 7. Also the counterclockwise movement of sector 21 against the rubber or similar frictional element 25, ensures disengagement of spring contact 26. When, however, the pedal returns, the circuit through contact 26 is completed and switch 7 is closed. As soon as the engine fires and speeds up, the generator G opposes the flow of current through the holding circuit and de-energizes the winding 16 so that the switch 7 opens. The field 27 of the generator is separately excited from the battery to secure higher voltage at low speeds. If the engine fails to start or makes a false start so that the generator G may not build up sufficiently to open the switch 7, depression of the pedal 3 opens both the holding and operating circuits of the winding 16 so that the switch 7 is opened. The return movement of the pedal repeats the starting operation. The resistance 23 and brush 22 of the holding control circuit may be replaced by resistance 23<1> which is always effective, so that the winding can then only be rendered inoperative by opening switch 11 should the engine fail to start.
