Abstract: 1,012,115. Multiple fastenings. JOHN TANN Ltd. Sept. 7, 1964 [Sept. 11, 1963], No. 35836/ 63. Heading E2A. A strong room or safe door 1 having mechanism for locking bolts on the door against withdrawal, including a chain or the equivalent holding the locking mechanism out of operative position, is provided with means for relieving the tension on the chain or equivalent, operated by contact of a drill with a plate 10 covering at least the vulnerable portions of the door. As shown, in which a pivoted latch 6 is normally held by a chain 7, to permit operation of bolts 2 by handwheel mechanism 4 when one or more locks 5 are released, one end of the chain is carried by a stub 14 projecting from the inside of the door 1 and extending through a drill-resistant metal plate 10 and another plate 15 also secured to the door, such that pressure on a drill applied to the plate 10, displaces the chain from the stub 14 thereby to free the latch 6 and block the bolts 2. The latch 6 is simultaneously locked in the released position by a spring-loaded bolt. In another arrangement, a sheet of armoured glass of the kind which shatters when its skin is broken normally supports one end of a lever to the other end of which the chain is attached. The chain may include a fusible and/or frangible link.

Abstract: 1,199,755. Parametric devices. TDK ELECTRONICS CO. Ltd. 9 Aug., 1967 [13 Aug. 1966 (2)], No. 36620/67. Heading H3B. A parametron is formed by the combination of an open-ended coil 2, Fig. 1, and its distributed inter-turn capacitance, the coil being wound on a conductor 1 coated with a magnetic film and inductively coupled with an input coil 3 and an output coil 4 formed on printed circuit boards 5. A three-stage logic circuit is shown, the A.C. excitation current being biased and applied cyclically and in turn to the conductors I of the three stages I to III. Several spaced open-ended coils 2 may be wound on the same magnetic conductor. The output coil 4 serves as a shield ring which prevents disturbance by external signals, and where a plurality of open-ended coils 2 are arranged in a single conductor, ferromagnetic end plates 7, Fig. 7A, may be provided to prevent interference between adjacent coils. Additionally ferromagnetic guard plates may be provided, Fig. 16A (not shown). A three-dimentional logic circuit is described in which ferromagnetic sheets 7, Fig. 8A, have alternate large and small apertures 9, 10. Each plate serves alternately as guard plates and end plates in the direction of stage progression, the wound conductors 1 being alternately offset to provide the required orientation between the apertures and the open-ended coils 2. A constructional detail is shown in Fig. 9 in which conductive rods 11 are coated with an electrodeposited layer of nickel permalloy, and the open-ended coils 13 are wound on a celluloid tube. The output and input coils are carried on printed circuit boards 16 which are assembled into a sandwich structure with apertured ferromagnetic plates 15 and spacers 17. A three-dimensional logic circuit is assembled by threading ferromagnetic plates 14, 15, the printed circuit boards 16 and the spacers 17 on a matrix of vertical alignment rods 19, the assembly being bonded together by heating a previously-applied thermoplastic, the rods 19 being removed. The magnetic film coated wires with their celluloid liners are then inserted through apertures in the structure, and are connected to terminal plates, Fig. 12 (not shown), the plates and wires being then covered with an insulating solidifying solution. The Specification discloses two constructional modifications, Figs. 13 and 14 (not shown), in which a stack of celluloid tubes is used with each magnetically coated wire.

Abstract: 878,592. Radio navigation. SERVO CORPORATION OF AMERICA. Oct. 28, 1959 [Feb. 20, 1959], No. 36670/59. Class 40(7) Relates to V.H.F. omni-directional ranges (V.O.R.s) in which the azimuth-dependent data is contained in a wave 30% amplitude-modulated at 30 c/s. and the azimuth reference is given by a 9À96 kc./s. sub-carrier frequency modulated at 30 c/s. with a maximum deviation of 480 c/s., the sub-carrier being 30% amplitude-modulated on the transmitted carrier, the airborne receiver comparing the phases of 30 c/s. filters one of which is fed from an F.M. detector connected to a 9À96 kc./s. filter. According to the present invention a Doppler-effect omni-range is provided using an aerial aperture of at least two wavelengths at the carrier frequency and is V.O.R.- compatible. Reduction of site &c. errors is thus afforded and existing aircraft receivers may be used for standard V.O.R. reception. The beacon Fig. 1 comprises a fixed aerial 9 fed from an amplitude-modulated amplifier 3 at a carrier frequency F and a commutated aerial array, Fig. 2 (not shown), fed with a carrier frequency of F9À96 kc./s.; a 30 c/s. signal is derived from an alternator 4 driven by a motor 5 which also commutates the aerial at 30 r.p.s. Harmonic generator 22 may be included to increase angular resolution and speech modulation may be impressed on modulator 7. The aerial commutation described comprises a whirling primary coil and a ring of secondary coils connected to a corresponding ring of fixed aerials; or a whirling single aerial may be used. To ensure a frequency difference of 9À96 kc./s. between the carriers of the fixed and commutated aerials a stable oscillator 19 and reactance tube 13 are used. 48 aerials in a ring of 5À1# diameter are provided to give maximum Doppler-effect deviation. The airborne receiver Fig. 3 is partly of known form and to utilize the additional high resolution channel 39, 40 is provided. Since the Doppler-effect frequency deviation is proportional to cos. (elevation), a constant amplitude signal is fed from unit 41 to F.M. detector 36 the output of which is fed to indicator 44 via potentiometer 42 to allow for carrier frequency value; the indicator may be an A.C. voltmeter with cosinelaw calibration marks and reading directly in elevation.
