Title: Improvements in electrical cable design
IPC: H01B13/06
Filed: 1942-02-03
Abstract: 555,152. Electric cables. LANE, N. Feb. 3, 1942, No. 1429. [Class 36] An electric cable has two or more conductors insulated by granulated or particulated dry sand or fused silica, the cable having concentric conductors or a multicore within an outer sheath. The sheath may consist of copper or steel tape, lead tubing or combined copper tape and lead tubmg. The cable is made by drawing the inner conductor IC through a hopper H containing the insulating material, with which it passes to a taping-head TH<SP>1</SP> where the outer sheath or conductor OS is formed. The cable then passes to a second taping-head TH" where a steel sheath PS is applied, and this may be covered by a lead or other damp-excluding sheath. Spacing pieces may be applied during manufacture to maintain the disposition of the conductors, and the cable ends should be closed or plugged.

Abstract: 1,010,964. Grinding aspherical surfaces. DIRECTOR OF KOGYOGIJUTSUIN.Oct.28, 1961 [Dec. 14, 1960], No. 15511/61. Heading B3D. In a process of producing a precise aspherical surface A on a rotatable workpiece by means of a rotatable grinding tool B, the axis of rotation of the tool is angularly displaced with respect to the position of the axis of rotation of the tool necessary to produce a spherical surface, such as to produce the required aspherical surface on the workpiece. The axis of rotation of the tool may be displaced with respect to the axis of rotation of the tool necessary to produce a spherical surface such that the displaced axis lies in a plane parallel with the plane containing the axis of rotation necessary to produce the spherical surface, the displacement being effected prior to the angular displacement. In the arrangements shown in Figs. 5A and 5B a grinding wheel B 1  grinds a spherical surface and a grinding wheel B 2  grinds an aspherical surface. A machine for carrying out the process is shown in Fig. 6.

Filed: 1968-01-11
Abstract: 1,249,300. Glazing. IMPERIAL CHEMI. CAL INDUSTRIES Ltd. 2 Dec., 1968 [27 Dec., 1967; 11 Jan., 1968], Nos. 58669/67 and 1566/68. Heading ClM. [Also in Division C7] An electrode, which may be used as an anode in a Hg cathode cell for the electrolysis of brine, comprises a support material in the form of a "valve metal" carrying on at least a part of its surface a layer of an "operative electrode material" in combination with an "inorganic glaze". "Valve metal" means Ti, Zr, Nb, Ta, W or an alloy comprising more than 50% by weight of one of these metals. "Operative electrode material" means an electroconducting material which is active in transferring electrons to or from the ions of an electrolyte and which is resistant to electrochemical attack. The material may be a platinum metal (i.e. Pt, Rh, Ir, Ru, Os, Pd or an alloy of two or more of these metals) and/or oxides thereof. "Inorganic glaze" means an inorganic oxide or a combination of such oxides which has been laid down by solidification in the vitreous condition from the molten state. The electrode may be made by depositing on the valve metal a coating of the operative electrode material, applying over the coating a layer of an inorganic glazing composition and melting the glaze. Alternatively, both the operative electrode material and the glazing composition may be deposited in a single step from a suspension containing particles thereof. The glaze may comprise silica, titania and zirconia. The glaze may be produced by coating the electrode with an aqueous sodium silicate solution optionally containing titania and then firing the coating. In an example, Ti was etched in oxalic acid; coated with Ru by painting on a mixture containing ruthenium chloride, isopropyi alcohol and, as reducing agent, linalool and then heating at 300‹ C. in air to dry; the Ru coated Ti was then heated in air at 450‹ C. to oxidize at least the outermost part of the Ru layer; glass enamelling slip was applied and melted by heating at 590‹ C. The slip consisted of PbO, B 2 O 3 , SiO 2 , CdO, Na 2 O, kaolin and H 2 O.

Title: Improved valve arrangement
IPC: G05D16/10
Filed: 1944-01-28
Abstract: 589,231. Shock-absorbers. ARMSTRONG, F. G. G. Jan. 28, 1944. No. 1641. [Class 108 (iii)] [Also in Group XXIX] In an arrangement of two oppositely-acting release valves for controlling the flow of liquid in a hydraulic circuit and which includes at least three relatively-movable parts each presenting at least one valve surface, disposed co-axially, both said valves being influenced by a common thermal-responsive element, the element also controls an independent leak orifice adapted to byepass one of or both the release valves. In the arrangement shown, a casing 20 having a detachable end plate 21 and side ports 22, 23, houses a thermal-responsive hard rubber tube 18 surrounded by a rigid support 29 and loosely fitted on a spindle 19 formed with two flats 36 and a circumferential groove 37, a valve head 30 and valve element 17 being slidable on the spindle. A spring 26 is positioned between the plate 21 and a collar 28 on the spindle the other end of which engages a bore 24 in the closed end of the casing. A second spring 33 is positioned between a second collar 35 on the spindle and the valve element 17 and acts on the latter to press the valve head 30 against the rubber tube 18. The pressure release valves are constructed by co-operating surfaces 11, 12 on the valve head 30 and casing and by co-operating surfaces 13, 14, valve head and element 17, while the leak orifice is constituted by surfaces 15, 16 formed on the element 17 and on the spindle 19. In operation, if the fluid pressure at the port 23 exceeds that at the port 22 sufficiently to compress the spring 26, the valve surfaces 11, 12 separate and fluid passes from port 23 between the surfaces 11, 12 to port 22. If the pressure at the port 22 is the greater and is sufficient to compress the spring 33, the surfaces 13, 14 separate, valve 11, 12 being closed, and fluid passes from port 22 through radial bores 31 and an axial bore 32 in the valve head, and between the surfaces 13, 14, to the port 23. With equal pressure at both ports, both valves are closed. On increase of temperature tube 18 expands to a greater extent than the spindle and, assuming valve 11, 12 is closed, the springs 26, 33 are compressed and the surfaces 11, 12 and 13, 14 pressed together with greater force, while, simultaneously, the surface 16 approaches the surface 15 to reduce the size of the leak orifice. Thermal-responsive elements other than of rubber may be used.
