Title: Missiles
IPC: F42C19/06
Filed: 1962-07-27
Abstract: 1,005,600. Fin-stabilized missiles and fuzes therefor. OERLIKON-BURHLE HOLDING A.G. July 27, 1962 [Aug. 9, 1961], No. 29061/ 62. Heading F3A. A fin-stabilized missile, Fig. 1, provided with an electric fuze F in which contacts are closed on impact to discharge a current through a detonator 16 is provided with means whereby the contacts may be closed other than by direct impact, the means comprising deformable resilient members housed within sensing devices 5 placed along the edges of the fins 4 and along the missile body 1. The devices 5 are made of resilient material, e.g. rubber, Fig. 3, and house a thin steel strip 10 insulated by the housing from a helically coiled wire 11 therein, except in the region of a gap 9 where the wire may be forced against the strip by a blow on the edge of the fin or on the body 1. The strips and wires are electrically connected by conductors 12, 13 to conductors 28, 29 respectively, which are in circuit with a battery 15, the detonator 16 and a switch 18. Due to the resilience of the devices 5, although the wires 11 and strips 10 may be accidentally brought into contact due to pressure in handling and transport, as soon as the pressure is released, the contact is broken and firing of the detonator cannot take place if the switch 18 is closed at launching of the missile. The fuze body 23 is surrounded by a spring 27, which supports a two-part hood 26 of conductive material connected by conductor 29 to the switch 18, the conductor 28 being connected to a conductive sleeve 25 so supported by an insulating sleeve 24 within the body 23 that, if direct impact occurs, the hood 26 and sleeve 25 are forced into contact. The circuit to detonator 16 is then closed, if switch 18 has been closed. If indirect impact occurs pressure on the devices 5 can also bring about firing of the detonator. The devices 5 may be replaced by wires 21, Fig. 9, which extend from the fin tips to end in sleeves 33 mounted in extensions 31a of a hood 31 separated by insulation 30 from the hood 26. If indirect impact occurs and one or more of the cords 21 is tensed by a blow, hood 26 is tilted into contact with sleeve 25 and completes the circuit to the detonator. A cord may connect all the cords 21.

Title: Improvements in or relating to radio compasses and radio direction finding systems
IPC: G01S3/14
Filed: 1939-11-03
Abstract: 536,178. Directive wireless systems. STANDARD TELEPHONES & CABLES, Ltd., EARP, C. W., and COLES, R. V. Nov. 3, 1939, No. 29315. [Class 40 (v)] Relates to a radio-compass of the kind described in Specification 490,940 where the signals received from a pair of crossed frame aerials are each separately modulated before being combined on a common amplifier and fed to an indicator. According to the invention the input to and output from the modulators are periodically changed-over by a switch. As shown in Fig. 1, signals from a North-South aerial N, S, are applied to push-pull amplifiers M<SP>1</SP>, M<SP>2</SP> together with a lowfrequency modulating-frequency O<SP>1</SP>. Similarly signals from an East-West aerial E, W, are applied to the amplifiers. M<SP>3</SP>, M<SP>4</SP> together with a modulating-frequency from O<SP>2</SP>. The modulated outputs are combined through a phasing valve PV with the signals from a non-directive aerial V. One part of the resulting signals is fed to a pair of phones OP. The other part is applied to the search-coil S of a dynamometer (or to the deflecting coils of a cathode ray tube) the field-coils being fed with currents from the modulators O<SP>1</SP>, O<SP>2</SP> respectively. To detect any unbalance in the circuits, the coil NS is switched over to the amplifiers M<SP>3</SP>, M<SP>4</SP> and the coil WE to the amplifiers M<SP>1</SP>, M<SP>2</SP>, and the connections to the field coils CN, CS, CW, CE, are simultaneously reversed. The mean reading of the two indicators then gives the correct bearing. If quadrantal error is present, it can be compensated by modifying the relative effectiveness of the field coils, for instance by means of a variable shunt resistance.

Abstract: 377,850. Stereotype. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Wood Newspaper Machinery Corporation ; 501, 5th Avenue, New York, U.S.A.) Oct. 22, 1931, No. 29329. [Class 100 (ii).] A mould for making a soft metal casting, particularly a curved stereotype plate, is provided with means for making a positive connection between the riser or tail of the plate and a part of the mould to hold the tail on the mould part after cutting from the plate until the connection is forcibly broken. As shown, the core 10 of a stereotype mould is provided with a strip 13 secured in place by screws 15 and formed with undercut portions 14 preferably in the form of notches, the strip extending substantially throughout the length of the space in which the tail is cast. When the tail is cast it is formed with integral dovetailed teeth which will hold the tail on the core when the cast plate is severed and removed. The pushers for removing the tail from the core will engage the edges of the tail and bend it about the strip 13 so as to facilitate removal. Alternatively, the core may be formed with an undercut recess in which a projection on the tail is cast, this projection being left in the. recess when the tail is broken away, but the new metal when poured into the mould will unite with that in the recess to form an integral projection on the tail.

Title: An improved alternating current relay
IPC: H03C1/10
Filed: 1924-12-09
Abstract: 226,525. K÷nemann, H. Dec. 9, 1924. Magnetic modulating systems and apparatus. -Speech and like currents are amplified by causing them to control by means of a circuit w the saturation of a frequency-multiplying transformer. High-frequency currents in circuit I from, for example, the transmitting alternators appear in circuit II as modulated current of a suitable multiple frequency (which may however be the same as that in circuit I) and are rectified by the device G. The resulting low frequency currents are then made to control a similar but suitably larger arrangement, and so on. The Specification as open to inspection under Sect. 91 (3) (a), describes a differential arrangement, Fig. 2 (Cancelled). Currents from circuit I normally produce currents of equal amplitude in circuits II, III which are tuned respectively to frequencies slightly above and below that of a suitable harmonic. The rectified currents are fed in opposition to a circuit L. The balance is upset by speech currents in circuit w and amplified repeat currents appear in circuit L. This subject-matter does not appear in the. Specification as accepted.

Title: Improvements in or relating to steering mechanism for motor vehicles
IPC: B62D7/15
Filed: 1938-10-17
Abstract: 523,656. Motor-vehicle steering mechanism. BLAGDEN, W. M. Oct. 17, 1938, No. 29971. [Class 79 (v)] In steering mechanism operable on all four wheels of a vehicle a single manually controlled member can be made to act at will either upon the front wheels or the rear wheels or on both in succession, the wheels which are not steered being automatically locked. In the construction shown a floating lever 9 has three pins 6, 7, 8 working in slots 2-5 in a fixed plate 1, the pin 6 being connected by a link 10 to the steering gearbox and the pins 7, 8 by links 12, 13 to the track rods 16, 17 respectively of the rear and front wheels. The lever .9 is pulled towards a pin 27 by a spring 251 and is moved away from the pin by a block 22 which slides in a slot 21 in plate 1 and is operated by the hand lever 25 which also controls the reversing gear. When the reverse lever 25 is in forward or neutral position the block 22 holds the lever 9 in the position shown in Fig. 3 in which the pin 7 lies in a recess 20 in the slot 2 and the rear steering wheels are thereby held against steering movement. Operation of the steering gear now rocks the ]ever 9 about pin 7, the pins 6, 8 move in the slots 3, 5, and the front wheels are steered. As the lever 9 rocks the pin 7 is gradually withdrawn from the recess 7 until, when the front wheels have been steered through about two thirds (say) of a complete lock, the pin 7 leaves the recess and the rear wheels commence to be steered. The pin 8 on the lever 9 now moves into one of two recesses 23 at the end of slot 5 and forms a pivot for the lever, so that the front wheels are now restrained from any further movement and the rear wheels complete their movement. When the vehicle reverses the rear wheels only are steered, the front wheels being locked against steering by movement of the reverse lever 25. This slides the block 22 to allow the spring 25<SP>1</SP> to move the pin 8 into the slot 21, thereby locking the front wheel steering gear, and bringing the pin 7 into the slot 2 and the pin 6 through a gap 26 into slot 4. Operation of the steering gear now rocks the lever 9 about pin 8 and steers the rear wheels only.
