Title: Coaxial line to waveguide coupler
Inventor: DAVIES ROBERT
IPC: H01P5/103
Filed: 1967-02-24
Abstract: 1,127,724. Impedance matching. MULLARD Ltd. 24 Feb., 1967, No. 8985/67. Heading H1W. In a coaxial line to waveguide coupler, a rectangular waveguide W has a conductive cross-bar 4 across its width at a position spaced from a short-circuited termination of the waveguide, a coaxial line C having its outer conductor attached to a broad face of the waveguide and its inner conductor 2 extending into the waveguide to contact the cross-bar, which cross-bar has extensions 6 which constitute the inner conductors of a pair of short-circuited coaxial sections 5 extending from the waveguide. Coaxial sections 5 are arranged to have the same characteristic impedance as the bar 4 in situ; the distance of the bar from the short-circuited end of waveguide W is chosen to minimize the variation with frequency of the resistive component of the waveguide impedance; the spacing H between the bar and the broad side of the waveguide to make the resistive component equal to the characteristic impedance of the coaxial line C; the length A to make the reactive component of the waveguide impedance, and the reactance for transmission along bar 4 change sign at the same frequency; and the dimensions of the waveguide, bar, and coaxial sections 5, to make the variation with frequency of the waveguide reactance and the reactance for transmission along bar 4 equal and opposite. A modified arrangement (Fig. 2, not shown) provides for D.C. access to the cross-bar and coaxial line inner conductors 2 by continuing the inner conductor 6 through a tubular polystyrene insulator supported in an earthed conductor having a #/4 radial choke situated #/4 from the end of the coaxial section 5.

Title: Improvements relating to metal detectors
IPC: G08G1/042
Filed: 1964-03-04
Abstract: 1,012,196. Vehicle presence detecting arrangement FERRANTI Ltd. March 4, 1964 [March 9,1963], No. 9270/64. Heading G1N. In a metal or vehicle presence detecting arrangement presence recording means is arranged to be actuated only if a change in potential at a point in the circuitry occurs at a rate greater than a critical value and in a particular predetermined sense. The approach of a vehicle to a coil DL changes the frequency of a transistor oscilator Q1 and in consequence the value of a potential applied to the emitter of transistor Q4 by rectifier CR1. Recording device "REC" is operated through transistor amplifiers Q2, Q3, Q5 the first two of which have a feedback path including a diode CR2 whereby the circuit is effective to changes in the said one direction, and a circuit of predetermined time constant C5, R6 whereby slow changes are rendered ineffective. The recorder is released for operation by a subsequent vehicle after a predetermined time if the first vehicle remains stationary over the coil, and it is not reoperated when the stationary vehicle moves away. Slow changes exemplified are slow moving vehicles, snow, or rain. The potential across capacitor C5 may be used to measure the period of a vehicles stay. Alternative arrangements may use a capacitor sensing probe and/or thermionic devices other than transistors.

Abstract: 1,143,963. Vehicle anti-theft devices. L. C. H. JUY. 3 March, 1966 [4 March, 1965], No. 9439/66. Heading B7J. [Also in Divisions E2 and F1] A vehicle anti-theft device for locking the steering column (or gear lever) and controlling an ignition, and a starting, electric circuit, comprises a spring-loaded bolt 7 slidably extendable by an eccentric member 6 acted on by a key-operated lock 3 to a position in which the bolt 7 (or a catch 10 thereon) engages directly in the steering column B (or in a sleeve M thereon), and a sleeve 2 manually rotatable by its shoulder 2a upon a metal body 1 fixed to a support S, so as to make or break the ignition and starting circuits, wherein the bolt 7 cannot be moved to lock the steering while the ignition circuit is made, and the sleeve 2 cannot be rotated to make the ignition circuit while the bolt 7 locks the steering. The sleeve 2 is operated at 2d for the bolt 7, and at 2c for the tongue 7c of the bolt 7. A conductive switch plate 19 is received at 2g in the sleeve 2, and has projections resiliently locating in apertures 2h so that terminals 19b, (19c), (19d) on the plate are urged towards contacts (14a), 15a, (16a), connected into the ignition and starting circuits. The terminals 19b, (19c) are circumferentially elongated. When the bolt 7 locks the steering and ball 22 engages the notch 2k in the sleeve 2, the contacts 15a &c. do not engage the terminals 19b &c. Partial rotation of the key 4 retracts the bolt 7 from the steering column but rotation of the sleeve 2 is prevented and the key 4 is withdrawable. Further rotation of the key 4 further retracts the bolt 7 so that the sleeve 2 can be rotated until the ball 22 . engages a notch 2m in the sleeve 2 whereupon the terminals 19b, (19c) engage the contacts (16a), 15a to complete the ignition circuit. Further rotation of the sleeve 2 against a spring 21 causes the starting terminal (19d) to engage the contact (14a) to complete the starting circuit, the terminals 196, (19c) still engaging the contacts (16a), 15a.

Abstract: 814,312. Gas turbine plant. TECHNISCHE STUDIEN A.G., FUR. March 29,1956 [March 29, 1955], No. 9938/56. Class 110 (3). [Also in Group XXXII] A mounting for supporting a rigid unit which includes a steam or gas turbine and associated apparatus, comprises a number of leaf springs connected at their lower ends to a bedplate or other base and designed to be connected to the rigid unit at their upper ends, the leaf springs each having flexible portions adjacent their ends and a reinforced middle portion between the two flexible portions. A highpressure turbine 1, a low-pressure turbine 2, a heat exchanger 3, a cooler 4 and a compressor 5 forming part of a gas turbine engine are assembled together to form a single rigid unit. Compressed air from the compressor 5 is led to a heater (not shown) which feeds the turbine 1. The turbine 1 discharges into the turbine 2 which exhausts through the heat exchanger 3 and cooler 4 to the intake of the compressor 5. The unit is supported from the bedplate by two pairs of supports 15, 16. The supports 15 which consist of leaf springs 17 reinforced in the middle section by elements 18, are attached at one end 19 to opposite sides of the heat exchanger 3 and at the other end 20 are clamped to the bedplate. These supports allow the heat exchanger to expand radially. A guide key 23 provided on the axis of the bedplate engages a groove 24 in a part of the heat exchanger to prevent its lateral displacement. The supports 16 are of similar construction to the supports 15 but are arranged so that the bending axes are at right angles to the machine axes. The supports 16 allow the unit to expand axially but not radially. Since the machine casing 6 is comparatively cool there is practically no radial expansion. The invention may be applied to a unit formed by a steam turbine and condenser. The supports 16 may be replaced by a single support on the axis of the bedplate.
