Abstract: 1,220,114. Laminating with synthetic resin interlayer. CESKOSLOVENSKA AKADEMIE VED. 29 April, 1968 [12 May, 1967], No. 20171/68. Heading B5N. A hydrophilic polymer or copolymer of glycol methacrylate or acrylate is bonded to a hydrophobic layer by creating one or more intermediate layers between the hydrophilic and hydrophobic polymers, the hydrophilic properties of the intermediate layer(s) decreasing gradually or stepwise from the hydrophilic to the hydrophobic polymer. The intermediate layer can be formed first and the two articles to be bonded together are then glued on e.g. by polymerizing monomers between them and the intermediate layer, or by adding further intermediate layers with different hydrophilic properties, or by a suitable adhesive e.g. an epoxy resin for metal. The intermediate layer can be formed by gradually applying layers on to each other; or by controlled diffusion of the monomer forming the hydrophobic (hydrophilic) component or of a mixture of such monomers into the hydrophilic (hydrophobic) polymer and polymerizing the diffused monomer e.g. by heating, ionizing radiation or chemically. Specific embodiments relate to the bonding of polyglycol methacrylate/acrylate to polymethyl methacrylate, polystyrene, epoxide resins, metals. In the examples: (1) a copolymer of ethylene glycol monomethacrylate and ethyl methacrylate was cast into a layer on a horizontal glass plate. On to this layer a foil of crosslinked polyglycol methacrylate was formed by polymerizing a mixture of glycol methacrylate, glycerol and di-isopropyl percarbonate. The double layer product was removed from a glass plate and the copolymer layer joined with a polymethyl methacrylate article by means of methyl methacrylate monomer polymerized .therebetween; (2) on to a polyglycol methacrylate foil provided on both sides with intermediate copolymer layers as in (1), there were glued blocks of polymethyl methacrylate by means of a viscous solution of polymethyl methacrylate; (4) a solution of a block copolymer of ethylene glycol monomethacrylate and epoxide resin was cast into a layer on a glass plate and a polyglycol methacrylate layer formed on the copolymer as in (1). The double layer product was swelled in water and removed from the glass plate, dried and glued to a roughened and degreased copper sheet.

Filed: 1954-07-09
Abstract: 751,824. Washing gases. SIMPSON CORPORATION, H. July 9, 1954, No. 20199/54. Class 55(2). Dust containing gases are washed by first contacting the gases with a liquid, such as water, so that droplets of the liquid are entrained in the gases which are then passed upwardly through a filter bed and at such a velocity that the liquid and dust particles deposited in the filter bed are washed upwards to form a layer of dust-laden liquid of a predetermined maximum depth on top of the filter bed. As shown in Fig. 1 dust-laden gases enter a washing apparatus 10 by an inlet 12 leading to a horizontal pipe 23 with an upturned end 24 which is partly immersed in a body of water 17 and in communication therewith by a branch pipe 25. Gases with entrained water pass upwardly through a filter bed 15 composed of glass balls supported on a foraminous tray. A layer 26 of dust laden water is formed above the filter bed 15 and an overflow 28 returns this dust-laden water to the base of the apparatus. Sediment is removed by a conveyer 30 and the gas leaving the filter bed 15 passes upwardly through subsidiary filter beds 16 to leave the apparatus at 14. In a modification the dust-laden gases enter the apparatus by a central duct and the filter beds are of annular form. The entering gases are discharged over a conical deflector into a saucershaped baffle which is partly submerged below the level of the water in the bottom of the apparatus. In a further modification the gases enter by a pipe with an upturned end into which water is fed so that water is sprayed into the upwardly moving dust-laden air.

Filed: 1938-07-11
Abstract: 503,296. Magnesium. METALLGES. AKT.-GES. July 11, 1938, No. 20453. Convention date, March 30, 1938. [Class 82 (i)] In a process for producing magnesium by heating magnesium chloride with hydrogen, the magnesium chloride is vaporized in a heated vessel 14 before being introduced into the reaction chamber 1, the evaporation being promoted by passing hydrogen through the evaporation chamber, and thence into the reaction chamber. The reaction chamber may be externally heated, in which case the outgoing heating gases may be used to heat the hydrogen, or to evaporate the magnesium chloride, or for both purposes. In the apparatus shown, the mixture of magnesium vapour, hydrochloric acid, and hydrogen resulting from the reaction in the chamber 1 passes in succession into a cooler 6 in which the magnesium is deposited, a heat-exchanger 7, an absorption apparatus 8 which removes the hydrochloric acid, and a drier 9 for the hydrogen. The hydrogen then passes through the heatexchanger 7, a jacket surrounding the cooler 6, a heat-exchanger 11 heated by the gases from the heating-jacket 2 of the reaction chamber, and thence, wholly or in part, over the surface of the magnesium chloride in the vaporizer 14 before returning to the reaction chamber. The heating-gases after passing through the exchanger 11 serve to heat the vaporizer 14.

Filed: 1967-05-03
Abstract: 1,174,671. Transistor pulse dividing circuits. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 3 May, 1967, No. 20500/67. Heading H3T. A pulse halving circuit comprises a pair of transistors TRA, TRB and a pair of relays PA, PB, each relay having only a single make contact, the interconnections between the transistors and relays comprising only diodes and resistors. Assume initially both transistors TRA, TRB are cut-off, and both relays PA, PB are de-energized. An input signal, provided by closure of a switch XI, connects earth to the emitter of transistor TRA to render it conductive, and relay PA operates to close contact PA1 putting earth on the output line OP. Opening X1 removes the earth from the base of TRB allowing it to become conductive and energize relay PB which locks in over contact PB1. 1. Closure of PB1 also cuts off transistor TRA, relay PA remaining energized via TRB. The next closure of switch X1 earths the base of TRB to cut it off, and relay PA releases to disconnect earth from output OP. The next opening of X1 removes earth from relay PB which releases to restore the circuit to its initial condition ready for another cycle.

Abstract: 677,255. Resistance measurements. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 17, 1950 [Aug. 17, 1949], No. 21440/49. Class 37. The resistance of a neutral/earth loop is determined by measuring the voltage across the ends of the loop with normal circuit current injected through the loop. By neutral/earth loop is meant the path which includes the route to earth via wiring conduit, apparatus casing, &c. in the consumer's installation and the route to earth via the supply system neutral line. In the circuit diagram shown, 8 is a three-pin plug inserted in a three-pin phase/neutral/earth socket in the installation under test so as to energize a step-down transformer 1 (e.g. secondary at 25 volts) and apply via the transformer secondary and variable choke 2 and ammeter 6 the normal circuit current, for example 10 amps, through the neutral/earth loop. Under this condition a voltmeter 7 connected to the plug 8 measures neutral/earth voltage. The voltmeter 7 may be scaled in ohms or the resistance value obtained from the voltage and current values. Errors due to system neutral/ earth voltage components may be minimized by swinging the injected testing current through 180 degrees with reversal of switch 3 and taking the mean of two voltmeter readings corresponding to the two switch positions. The off position of switch 3 permits determination of system neutral/earth voltage before testing. The maximum permissible loop resistance may be based on 40 volts as maximum neutral/earth voltage under normal circuit current conditions. The Specification includes an illustration (not shown) of a portable casing incorporating the required testing components including neon indicating lamp 5.
