Title: Apparatus for manufacturing extension springs
Inventor: SHIGUMA HEIJIRO
IPC: B21F3/00
Filed: 1968-12-16
Abstract: 1,255,947. Coiling helices; making springs. NHK SPRING CO. Ltd. 16 Dec., 1968, No. 59613/68. Headings B3A and B3E. Apparatus for feeding and coiling a spring wire 112 comprises a rotatable mandrel 102, a reel device 30 having a reel supporting member 105 horizontally mounted in a casing 104 so as to rotate about shafts 109 and 110, a reel assembly 107 mounted on the supporting member 105 and rotatable about a shaft 111 disposed perpendicularly to the shafts 109, 110, a guiding passage 106 passing through the casing, the supporting member and the shaft on the side adjacent the mandrel, and a mechanism 108 for rotating the reel device about the shafts 109, 110 whereby the wire 112 is twisted before it is wound on to the mandrel. In operation the leading end of the wire is connected to the mandrel 102 and the mandrel rotated to wind the wire so that adjacent turns are in close contact with each other. Since the wire is drawn by the mandrel, the reel 107 is rotated around the shaft 111 and the rotatable supporting member 105 is then rotated around the axis of shafts 109 and 110 in a gear ratio determined by the gear train of mechanism 108. As a result, the coiling wire is twisted before it is wound on to the mandrel and an initial tension is imparted to the wire.

Abstract: 1,273,820. Strip transmission lines; filters and non-reciprocal devices. R.C.A. CORPORATION. 12 Dec., 1969 [27 Dec., 1968], No. 60677/69. Heading H1W. A transmission line (Fig. 6) comprises a substrate 55 having a dielectric constant greater than 8, e.g. rutile which supports a conducting strip 51 and one or more coplanar ground conductors 52, 53 which are at least twice as wide as strip 51. Preferably the distance between the two ground conductors is less than half the operating wavelength, and the substrate thickness is more than twice the separation of the strip 51 and a ground conductor. The magnetic field at the dielectric-air interface between the conductors is stated to be substantially circularly polarized in the same sense on opposite sides of the strip 51 such that a resonant isolator or a differential phase shifter may be provided by placing gyromagnetic material 54, 56 between the conductors with a magnetic field bias in the direction 57. In another arrangement a field displacement isolator is provided by placing lamellar strips for example of resistive carbon sandwiched between low-loss dielectric teflon and a gyromagnetic material, with the teflon placed adjacent the dielectric substrate. In an alternative embodiment a slab of gyromagnetic material is mounted above and across the conductors. Directional coupler in Fig. 5 comprises transmission strips 42, 43 coplanar with ground conductors 45-48 on a dielectric substrate 40. The length of the strip lines in the coupling region 49 is preferably an odd multiple of a quarter of the operating wavelength. Resonant band pass filter in Fig. 11 comprises a centre conducting strip 91 and coplanar ground conductors 92, 93 on a dielectric substrate in which the centre strip is shorted at 99 to ground conductor 92 such that the portions 97 and 98 are mutually perpendicular and ground conductor 93 is extended in the region of 99 for the purpose of impedance matching. A sphere of for example yttrium iron garnet is placed near point 99 and there is applied a magnetic field H DC  to bias the gyromagnetic material near resonance at the operating frequency such that coupling occurs between portions 97 and 98 of the strip conductor 91 only for signals near the centre operating frequency.

Patent GB-2012026-A (GB)
Title: Improvements in and relating to valves
IPC: F16K17/24
Filed: 1979-01-24
Abstract: A valve, particularly of the type which closes automatically when, e.g., leakage of fluid occurs due to fracture of a downstream hose, comprises a valve member 3 slidable between an open position as shown and a closed position preventing or restricting flow of fluid in the direction of arrow 9. The valve member is urged towards its closed position by the differential pressure on the valve against the biasing force of a biasing means, e.g. spring-biassed balls or a polygonal spring 7. The biasing means exerts a radial force on the peripheral surface of the valve member such that, while the valve member is in its open position, the biasing means act against conical surface part 8b to produce an axial basing force component but when the valve member moves to its closed position the basing means act against cylindrical surface part 8c so that the axial force component is zero. Thus the valve member will not re-open until a reverse differential pressure is applied thereto. <IMAGE>

Title: Magnet assembly for support of a rotor
IPC: F16C39/06
Filed: 1980-12-19
Abstract: An elongated rotor 16 supported by a thrust bearing at its bottom end, is supported at the top end by coaxial tubular magnets 11 and 15. The magnet 15 is of shorter axial length and is mounted on the rotor. The inner magnet 11, poled in the same direction, is adhered or bonded to a magnet holder 12 mounted for damped radial movement by means of resilient rods 13 attached to the rotor housing. Axial relative movement of the magnets resulting from transverse forces acting on the rotor when rotating causes changes in radial stiffness and in axial forces due in each case to the magnetic interaction. The axial force can be tensile when the rotor is stationary and progressively change to a pressure against the thrust bearing as the rotor runs up to speed. Composite magnet construction, special shapes and forms of magnetization and magnetic screening can be used to control the magnetic interactions. <IMAGE>
