Title: Improvements in or relating to devices having non-reciprocal transmission characteristics
Inventor: DOUGHTY DOUGLAS CAMPBELL
IPC: H01P1/32
Filed: 1958-12-22
Abstract: 863,960. Non-reciprocal transmission devices. GENERAL ELECTRIC CO. Ltd., and DOUGHTY, D. C. Dec. 22, 1959 [Dec. 22, 1958], No. 41314/58. Class 40(8) A non-reciprocal transmission device comprises an element 7 of gyromagnetic material, e.g. ferrite, located in a region of circularlypolarized r.f. field generated by two parallel portions 4, 5 of a transmission line conductor which are excited in phase-quadrature. One end of the portion 4 is connected to a coaxial terminal socket 21 and one end of the portion 5 to a further socket 22, the other ends being connected together by a loop 1 of coaxial line of length (2n + 1) #/4 where # is the wavelength of the operating fre quency. A two-part brass block 8 provides a common outer conductor for the two parallel conductors 4, 5. The element 7 is in the form of a rod supported by a piece 19 of dielectric material at a point where the magnetic r.f. fields of the two conductors cross at right angles. It is subject to the longitudinallydirected field of a bar magnet 20 which is of a value sufficient to produce gyromagnetic resonance in the element. The effect is non- reciprocal as regards r.f. energy propagated between terminals 21, 22 and the device behaves as an isolator. Alternatively, the magnetic field may be adjusted to a value sufficient to produce a non-reciprocal phase delay. In a modification, use is made of four parallel conductors which, as seen in a section similar to that of Fig. 3, are arranged at the corners of a square with the ferrite element at the centre of the square. In order to produce the necessary circularly-polarized field, adjacent conductors must be excited in phase-quadrature and diagonally-opposite conductors in phase-opposition. In one arrangement, two transmission paths are provided by two adjacent pairs of conductors, the two conductors in each path being connected by a loop in the manner shown in Fig. 2. Each path is connected at one end to the input of the device and at the other to the output so that the paths are in parallel. In an alternative arrangement, the four conductors are in series and three loops are used each joining an adjacent pair of conductors. Specification 862,451 is referred to. Reference has been directed by the Comptroller to Specification 788,345.

Abstract: 918,267. Manifolding stationery. FANFOLD Ltd. March 24, 1960 [Dec. 24, 1958], No. 41752/58. Class 16. A continuous form stationery assembly comprises at least three superposed webs formed by folding a single wide web at least twice in zig-zag fashion along longitudinal lines of weakening, a row of feeding apertures along at least one marginal edge of the assembly, and transfer material between at least some adjacent webs. At least one web may be narrower than the overall width of the assembly. A single wide web is folded in zig-zag fashion along longitudinal lines of weakening 7 and as shown in Fig. 2 the webs 1, 2 ; 3, 4; 5, 6 are interconnected by lines of adhesive 13 (or by stitching or stapling). In addition, carbon webs 14, 16, 18 are secured between the webs 1-6 by said lines of adhesive 13 acting through rows of widely spaced apertures in the webs 2, 4. With reference to Fig. 7, the webs 2, 3 are connected together by a line of adhesive 13, which extends through rows of apertures in said webs to secure the carbon webs 14, 16 to the carbon web 15. The assembly is provided with a row of feeding apertures along each edge and is divided into form lengths by transverse lines cf perforations in the stationery and carbon webs. Longitudinal lines of weakening are provided in the webs 1-6 along the inner edges of the lines of adhesive 13. The widely spaced apertures may be dispensed with and each carbon web secured to the stationary web above by a continuous or discontinuous line of adhesive. The carbon webs may be replaced by a transfer coating applied uniformly or locally to the underside of the stationary webs.

Abstract: 914,906. Liquid fuel burners. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Dec. 9, 1959 [Dec. 10, 1958], No. 41922/59. Classes 75 (1) and 75 (3). [Also in Group XXVI] A burner for an aircraft engine combustion chamber 1 through which a gaseous flow travels at high speed comprises a divergent nozzle 2 supplied with hot liquid fuel, the length and divergence of the nozzle being such that the fuel is vaporized at least partially by expansion. The nozzle also comprises a convergent portion upstream of the divergent portion. The cross-section of the throat may be regulated by a needle valve 9. The end of the divergent portion is cut away over a semicircular area to allow part of the fuel to enter a recess 5 in the wall of the combustion chamber where it is ignited by a sparking plug 8. The uncut end of the divergent part may be flush with the combustion chamber wall as shown or may project into the chamber. The nozzle may be inclined upstream or directed in countercurrent to the gaseous flow in the combustion chamber. In a modification, Fig. 6 (not shown), the nozzle discharges into a cylindrical pipe 11 which leads to the combustion chamber and the fuel aspirates air into the cylindrical tube 11. The mixture so ignited by a sparking plug in a recess in the wall of the combustion chamber beside a cut-away portion of the end of the cylindrical tube 11. Figs. 7, 8, 9 (not shown) show a ring of nozzles mounted on the outer wall or on the inner wall of an annular post combustion chamber of a turbo-jet engine, the nozzles discharging in a radial direction. Nozzles producing short wide jets alternate with nozzles producing longer jets. Figs. 10, 11, 12 (not shown) show burners according to the invention mounted in alternate arrangement with conventional burners in a ring and discharging into an annular combustion chamber in the direction of the main air flow therein. Each nozzle of the burners according to the invention takes the form of two coaxial cones bounding a space which first decreases and then increases. Fig. 13 (not shown) shows nozzles according to the invention mounted on an aircraft upstream of a ram jet engine and discharging into the external air stream entering the engine. Fig. 14 (not shown) shows nozzles according to the invention mounted in a triangular wing and discharging into the external air flow below the wing.

Abstract: 879,143. Yarns and threads; preparing and treating fibres. ELOFLOCK OBERFLACHENVEREDLUNG G. m. b. H. Dec. 11, 1959 No. 42235/59. Classes 120(1) and 120(3) In a method of electrostatically coating a filament, yarn, thread, wire or like filamentary body, with particulate material such as short pieces of fibrous material or flock, the particles are subjected to the influence of two or more simultaneously produced electrostatic fields acting in succession on the particles during their movement relative to the filament, &c. Thus, particles after entering a coating zone may be subjected to a first electrostatic field directed towards a high potential mesh electrode through which they travel and, whilst maintaining the same direction of movement, are conveyed under the action of a second electrostatic field (which may be generated by the same high potential electrode) to the filament &c., which is at a quasiearth potential: particles carrying beyond the filament reverse their movement, return to their starting position, and the cycle recommences, so that the filament, which is adhesive or has an adhesive coating, becomes uniformly coated with particles. The enclosed apparatus shown comprises a storage container 2 wherein a supply of flock maintained from a hopper 27 is distributed by a rotating brush 3 (wings 4 of which carry brushes, bristles or rubber lips) over a resilientlymounted, foraminous closure or screen 5, a portion 6 of which is reciprocated by engagement of a catch on a shaft 7. Flock passes uniformly on to an endless conveyer 8, driven through an infinitely variable gear 9 from a motor which also drives shaft 7, and is carried beneath reciprocated, high-voltage and earthed, mesh electrodes 11 and 30 between which fibres oscillate under the influence of electrostatic fields and form a coating on filaments 29 supported within the casing in stretched condition. Excess fibres are collected in a hopper 16 to be blown by a fan 17 through a pipe 18 into container 2: air escapes through a permeable, accordian-pleated, fabric closure 19 from the underside of which fibres are shaken free by arms 24, 25, 26, actuated by engagement of wings 4 with lever arm 22. The mesh of electrode 11 may be larger than that of electrode 30.
