Title: Improvements in or relating to processes for connecting wires to printed circuits
IPC: H01R12/55
Filed: 1955-12-30
Abstract: 808,814. Making printed circuits; soldering. STANDARD TELEPHONES & CABLES Ltd. Dec. 30, 1955 [Dec. 31, 1954], No. 37414/55. Classes 83 (2) and 83 (4). In connecting an electrically conducting wire to a printed circuit formed on an insulating support, a hollow electrically conducting rivet having a hollow axial extension is fixed in the support for making electrical contact with the circuit, the extension being proud of one surface of the support, inserting the wire in the rivet so that a portion of the wire is in the extension and soldering the portion to the extension. A hollow rivet 1 with a slotted extension 10, a head 11 and an annular flange 2 is fixed in support 12 to be in contact with part 13 of a circuit etched from a copper plating. The rivet may be electrocopper-plated to the plating before the circuit is etched. The wires of components are held in such rivets by bending the slotted sides of the extensions and the support with components in position is located over a bath of molten tin 8 in which the extensions are dipped. A circuit may be provided on both sides of the support and the hollow rivet may connect the circuits.

Title: Process for the removal of hydrogen and/or oxygen from gaseous mixtures
IPC: G21C19/303
Filed: 1965-09-02
Abstract: Hydrogen and/or oxygen are removed from a gaseous mixture containing both by passing the gas through the gas-flow channels of a supported catalyst, the support of which comprises a catalytically inert unitary essentially crystalline refractory structure having a bulk density of from 0.45 to 1.05 grams per c.c. and a plurality of gas-flow channels extending therethrough and the catalyst deposited on the surfaces of said channels and on superficial macropores of said structure which communicate with said channels being an activated refractory metal oxide on which has been deposited platinum, palladium, rhodium, ruthenium or an alloy or mixture of two or more of these.  Free oxygen can be removed from gases such as H2, D2, N2, He, A, Ne and combination with hydrogen and H2 can be removed from O2, N2, He, A and Ne by combination with O2, the H2 or O2 required to remove the other may be added if it is not originally present in the stoichiometric amount required.  The reaction may be carried out at between -20 and 100 DEG  C. at a space velocity of 10-106 standard volumes of gas per volume of catalyst per hour.  The preferred supports are zircon-mullite and alpha alumina and may be prepared as described in Specification 882,484, and the preferred refractory oxides are of the gamma or activated alumina family.  The supported catalyst is described in Specification 1,052,105.  A gaseous mixture of oxygen together with H2 and/or D2 formed by radiolytic dissociation of H2O and/or D2O used as a moderator/coolant in a nuclear reaction may be combined using the catalyst.

Abstract: 832,861. Presses for separating liquids from solids. ETHYL CORPORATION. Dec. 9, 1957 [Dec. 10, 1956], No. 38182/57. Class 46. [Also in Groups V and XXII] A sludge containing finely-subdivided lead, a normally-liquid alkyllead compound and an aqueous liquid such as sodium chloride is forced through an extrusion aperture of appreciably lower cross-sectional area than the extrusion zone in which the pressure is applied, whereby the liquid phase is eliminated and the lead particles emerge as a rod. During initial application of pressure by a ram 19 in a cylinder 11 the solids are pushed closer together without significant deformation. Liquid thereby displaced escapes backwards through a clearance 18 (of the order of thousandths of an inch) between the ram and cylinder. In the region 15 the solids are flowing to a die aperture 13 with further liquid separation. Such liquid is expelled through the die-aperture with the rodlike product 16, a little of it adhering to the rod and the remainder falling as globules 17. The die may have two or more slots. Instead of the ram extrusion apparatus, screw extrusion apparatus may be used.

Title: Transit time diode oscillator

Abstract: 1275091 Semi-conductor device SEMICONDUCTOR RESEARCH FOUNDATION 1 Aug 1969 [1 Aug 1968] 38791/69 Heading H1K A transit time oscillator includes a junction which is reverse biased in operation so that carriers are injected by the tunnel effect, and transit a space charge region associated with the junction. In a first embodiment, Fig. 1 (not shown), a PNIN or NPIP device is constructed so that carriers are injected into the I type region by the PN junction by virtue of the tunnel effect which predominates over any avalanche effect present. In an example, a high resistivity P type layer is epitaxially deposited on a P type Si substrate doped with B which is then diced and an alloy of Ag, Pb, Sb and Al placed on the epitaxial layer and alloy diffused to produce the required structure. The substrate is soldered to a N-plated Mo body by means of an Al-Si foil. The device is placed in a cavity resonator and operated by applying pulses which reverse bias the PN junction. In a second example, a P type high resistivity layer is epitaxially deposited on a (100) surface of a P type GaAs substrate doped with Zn which is then inserted in a quartz ampoule together with Zn and As and the Zn diffused-in. Sn is evaporated on to the epitaxial surface and In is evaporated on to the surface of the substrate and both are alloyed in. The wafer is then subdivided by cleaving. Various other methods may be used including double diffusion, epitaxial growth, melt back, alloy-diffusion and diffusion followed by alloying. In a second embodiment, Fig. 2 (not shown), a tunnelling junction is produced by means of a point contact. In a third embodiment, Fig. 3 (not shown), the device comprises an abrupt PN junction diode which may be constructed by depositing a layer of N type GaAs doped with Sn on a polished and etched (100) face of a P type GaAs substrate doped with Zn by a solution growth method. The surfaces are lapped and nickel plated, the wafer is heated and then the surfaces are plated with Ni and Au. The wafer is then cleaved into squares or rectangles to form individual diodes which are soldered to the end of a Cu stem and mounted in a resonator, Fig. 7 (not shown). In a further embodiment a PIN structure is used in which the PI and NI junctions are abrupt, Fig. 4 (not shown), and this may be approximated to by a graded junction diode, Fig. 5 (not shown). The semi-conductor material may be of InSb, GaP or Ge instead of GaAs or Si.
