Title: Improvements relating to end fittings for flexible hoses, and hoses having such end fittings
Inventor: USHER STANLEY
IPC: F16L33/01
Filed: 1957-10-03
Abstract: 837,045. Hose end fittings. K. A. C. Ltd. Sept. 23, 1958 [Oct. 3, 1957], No. 31059/57. Class 99(1). In an end fitting for a flexible hose 3 of non - metallic material, e.g. rubber, synthetic rubber or a plastic such as polytetrafluoroethylene, the hose is trapped between a tubular spigot 1 and a sleeve 8 either or both of which is or are formed to resist withdrawal of the hose from therebetween, and the spigot and sleeve have complementary surfaces 4, 11, inclined to the axes thereof for sealing interengagement beyond the extremity of the hose. A ring nut freely rotatable with respect to the spigot or sleeve and having direct or indirect screw-threaded engagement with the other of these components secures the sleeve and spigot with the surfaces 4, 11, in fluid-tight sealing contact. As shown in Fig. 1, the spigot 1 has a frusto-conical portion 4 for sealing with the belled or radiussed part 11 of the sleeve 8 and an annular shoulder 5 which acts as an abutment for the shoulder 7 of a ring nut 6 screwed into the cylindrical extension 12 of the sleeve. The internal diameter of the sleeve is less than the external diameter of the hose and terminates in a portion 10 of a diameter substantially equal to the external diameter of the spigot. Furnished on the internal, and tapered, exterior surfaces of the sleeve are annular grooves 15 or the exterior surface is knurled, roughened or helically grooved. Where the hose is provided with an external sheath of braided metallic or non-metallic strands the sheath is gripped between the sleeve and the internal frusto-conical surface of an anchoring ferrule 17 formed with an internally screwthreaded, cylindrical extension 18 in which is engaged a ring nut 13 engaging the extension 12. To lock the assembly, a hole 19 is drilled through the ferrule, ring nuts and extension 12 and tapped to receive a screw 20. In modifications, (a) the narrow end of the sleeve is deformed inwardly by the ferrule to bite into and form a lip seal around the hose, (b) the ring nut 13 is omitted and the ring nut 6 is screwed into the extension 18 of the ferrule, and (c) the ferrule is swaged into the reinforcement-anchoring position thereof and interlocks with the sleeve and/or spigot.

IPC: F01P11/02
Filed: 1969-06-20
Abstract: 1,246,552. Container closures. FORD MOTOR CO. Ltd. 20 June, 1969, No. 31240/69. Heading B8T. [Also in Divisions F2 and F4] An I.C. engine cooling system filler cap, of the type having first and second valves 6 and 7 adapted to open automatically above and below predetermined pressures, incorporates a manual arrangement to relieve any excess pressure in the cooling system prior to removal of the cap from the filler neck (11, Fig. 2, not shown), which it closes. The filler cap and neck.(11) are provided with coacting cam surfaces so shaped that the cap must first be depressed to open the valve 7 before it can be rotated in the normal way to release it from engagement with the filler neck. Depressing the cap causes the extension 3a of a rivet 3 fixed to the main part 1 of the cap to bear down against a spindle 10 which opens the valve 7 against the force exerted by a spring 8. Any excess pressure in the system is thus released through aperture 9. The valve 6 seals against an internal shoulder formed in the filler neck under the action of a coil spring 5.

Title: Improvements in and relating to compensation elements for reducing the crosstalk in trunk communication cables
IPC: H04B3/34
Filed: 1934-10-31
Abstract: 432,515. Preventing inductive disturbance. SIEMENS & HALSKE AKT.- GES., Siemensstadt, Berlin. Oct. 31, 1934, No. 31267. Convention date, Oct. 31, 1933. [Class 40 (iv)] In order to minimize cross-talk in the case of lightly-loaded lines and high-frequency lines, it is important to balance the inductive couplings between conductors in addition to the capacity couplings, and this is effected by the use of corrective capacity elements which also provide an inductive coupling, the ratio of the inductive coupling being approximately the same as the corresponding ratio for the quads or conductor groups to be compensated. The ratio may be adjusted by varying the form and the spatial arrangement of the condenser plates and by suitable choice of dielectric or by interposition of magnetic material. Small supplementary capacity or inductance elements may be added if necessary. The element may be subdivided so as to provide an initial rough compensation and a supplementary fine compensation. The element may take the form of two or more coils inductively coupled together and dimensioned so as to give the desired capacity coupling. The elements shown are suitable for balancing quads and comprise four wires which are round in Fig. 1 and of angular section in Fig. 2 and which constitute the condenser plates. These wires are arranged in spiral quad form and are insulated by material 16 of high dielectric constant, the whole being surrounded by a sleeve 15, 25 of insulating material or of metal.

Abstract: 1307864 Klystrons PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 June 1970 [2 July 1969] 31311/70 Heading H1D A permanent magnet periodic focusing arrangement for a klystron includes, around each drift tube, a group of radially magnetized magnets, the magnets of a group being axially spaced from one another and magnetized in the same direction; the use of radial magnetization prevents undue beam diameter nipple, despite the small ratio between the axial extent of a group and the spacing between successive groups imposed by the presence of the intervening klystron cavities. The magnets may be in the form of annuli or spoked configurations (Fig. 8, not shown); successive groups may be magnetized either in the same or in opposite senses (Fig. 6 and 7, not shown); and the polepieces 3 may project into the cavities, as shown, or constitute part of the drift tubes. It is stated that by suitable choice of the number, diameter, and spacing of the magnets in the groups, and of pole shoe shape, the first Fourier component of the variation of the square of the axial magnetic field with position along the axis may be largely suppressed, to minimize beam diameter ripple (Figs. 3 to 7, not shown).

Title: An electric resistance material and a process for manufacturing same
IPC: H01B1/08
Filed: 1920-11-09
Abstract: A material which is probably a mixture of cuprous and cupric oxides and is obtained by fusing cupric oxide, is used as an electric resistance of the type having a negative temperature coefficient of resistivity.  The material may be produced by striking an electric arc between copper electrodes in contact with copper oxide, preferably in the form of a block formed by compressing and heating a mixture of powdered cupric oxide and water, the electrodes being gradually separated without breaking contact with the block so that the current flows through a molten path in the surface of the oxide owing to the reduced resistance of the molten oxide, and the material being collected from this molten path.  If direct current is used, the material collected near the positive electrode is a greater specific resistance than that collected near the negative electrode, this variation being increased by increasing the current.  The resistance of the material at normal temperature may be increased or decreased by subsequent heating in an oxidizing or reducing atmosphere.  The molten path may be maintained or increased by the addition of copper or powdered copper oxide.  According to the Provisional Specification, the block of copper oxide used in the fusion process may be formed by melting the oxide in a crucible and allowing it to cool.
