Title: Improvements relating to microwave rotating joints
Inventor: WARD ALAN WILLIAM
IPC: H01P1/06
Filed: 1963-09-06
Abstract: 1,112,402. Rotatable couplings. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 7 Dec., 1964 [6 Sept., 1963], No. 35352/63. Heading H1W. A rotating microwave joint, e.g. for the feeder of a rotating aerial, comprises a pair of coupled, mutually rotating, annular strip lines. The strip lines are of the triplate kind, i.e. they consist of a line (or double line) conductor printed on one or both sides of a dielectric layer arranged between, and spaced from, two parallel ground planes. Fig. 2 shows two such dielectric layers, an inner, rotatable, annular layer 16 and an outer, fixed, annular layer 3, the layers (as shown) being in the same plane. Corresponding pairs of rotatable and fixed ground planes of annular form (not shown) are connected respectively to the outer conductor 34 of a central rotatable coaxial line and to the outer conductor 32 of a fixed coaxial line. The ground planes overlap each other, one pair being rebated to accommodate the other. The fixed line conductor 4, printed on one or both sides of the layer 3, is connected at one end to the inner conductor of the line 31, 32 and at the other to a dissipative termination 23. A similar (rotating) line conductor 9 is connected to the inner conductor of the rotating line 33, 34. Coupling between the fixed and rotating lines is afforded by an intermediate line 17 and two annular arrays 18 of radial sectors spaced at quarter-wave intervals, all these being printed on the rotating dielectric layer 16. The construction behaves as a O db. coupler. In a modification, the fixed and rotating transmission lines are spaced apart axially (instead of radially, as shown), and are in the form of two parallel, annular triplates having a common intermediate ground plane. This ground plane is apertured at intervals to provide coupling. In this construction, a coupling array of the type indicated by 17, 18 on Fig. 2 may be printed on one of the dielectric layers or may be shared between both of them, e.g. with one array 18 on the fixed layer, the other on the rotating layer and two intermediate line conductors 17 coupled through apertures in the common ground plane.

Title: Improvements relating to electromagnetic waveguides
IPC: H01P1/18
Filed: 1946-11-29
Abstract: 624,781. Wave-guides. MILLING, M. C. CROWLEY-, and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Nov. 29, 1946, No. 35506. [Class 40 (v)] The lateral position of a section of a waveguide system with respect to its axis is made adjustable by including a looped portion between the movable section and a fixed section, the length of the loop being varied to maintain the electrical length of the wave-guide constant. The loop section may be connected to the fixed and movable wave-guide section through telescopic joints and a mechanical linkage provided so that variations in electrical length are automatically compensated. As shown, Figs. 2 and 4, the fixed guide A and the laterally movable guide C are integral with U-section members 1, 4 respectively. The U-shaped members 1, 4 co-operate with opposite sides of an H-section centre-piece 2 to form the sidearms B1, B3 of the loop wave-guide, the crossguide B2 of which is formed by a member 3 integral with the centre-piece 2. The centrepiece is preferably linked to the laterally movable guide C so that variations in electrical length due to adjustment of the lateral position of guide C are automatically compensated by variations in the electrical length of the loop guide B1, B2, B3. Specification 624,780 is referred to.

Station A may be an aircraft and station B on the ground. In the embodiment pulse pairs are utilized and data transmission is by digital amplitude or frequency or spacing or phase of a pulse pair. The direction finder consists of two pairs of aerials on orthogonal axes forming a wide-base system and two pairs of aerials on the same axes forming a narrow-base system; the connections between each pair of aerials and its pair of receivers, and between receivers and phase-difference evaluators, are interchangeable. Interrogating stations having the same azimuth modulate an identification signal on the interrogation pulses which they respectively transmit.

Abstract: 1,075,054. Gas analysis. MINE SAFETY APPLIANCES CO. Sept.1, 1964, No.35713/64. Heading G1B. A gas dosimeter comprises a sealed transparent tube 2 having a frangible end 5, and a bed of colorimetric indicator reactive with a gas to be detected to give a colour change within the tube and spaced from the end 5 by a plug 10 of porous material. The purpose of the plug 10 is to prevent extraneous air currents from reaching the surface 12 of the indicator bed. Gaseous diffusion into the bed causes a colour change in the indicator the length of the colour change zone being dependent on the concentration of the gas to be detected. In draught-free conditions the plug 10 may be replaced by length of narrowbore tube, but a small plug will also be required to keep the indicator bed in place. The indicator may be activated alumina impregnated with silver cyanide for H 2 S, a granular solid carrying the reaction product of tetramethyldiaminodiphenylmethane and an oxidizing agent for SO 2 , silica gel carrying a benzidine derivative for NO 2  Cl 2  or Br 2 , or activated alumina with thymol blue for CO 2 , and the plug 10 may be a wad of fibre or cloth such as glass wool or cloth or organdy or of sintered glass. A removable cap or stopper may be provided in place of the frangible end 5, and the tube 2 may be marked with a suitable scale or the tube may be mounted on a card incorporating a scale.

Title: Improvements in or relating to decorated rubber articles and methods of making the same
IPC: B29C37/00
Filed: 1932-12-17
Abstract: A decorated rubber article is produced by applying to an unvulcanized rubber base a liquid decorating layer of rubber which is of lower plasticity at all temperatures to which the rubber is subjected during vulcanization than the base.  The base layer may be of masticated unvulcanized rubber and the applied pattern of latex which is dried, the article then being vulcanized.  The lower, more plastic, layer flows around the applied decoration which becomes thus firmly embedded.  After vulcanization the two surfaces have different coefficients of friction, and may thus be used in the manufacture of inlaid motor-car steering wheels. Other articles referred to or illustrated are tyres, corrugated mats, hot water bottles, bath caps and shoes, toys, hard rubber table and desk tops, wearing apparael, &c.
