IPC: C09J7/38
Filed: 1963-06-26
Abstract: A pressure-sensitive adhesive composition comprises a mixture of (a) a non-crosslinking polymer and (b) a cross-linkable copolymer, said cross-linkable copolymer comprising the copolymer of the monomeric units of the polymer (a) and a cross-linkable comonomer.  A cross-linkable comonomer is defined as one which when polymerized with one or more other monomers will result in the formation of a polymer containing a pendant reactive group which will self-cross-link.  Preferably the composition of the cross-linkable copolymer is very similar to the composition of the non-cross-linking polymer.  Cross-linkable monomers specified are N-methylol acrylamide, glycidyl acrylate, hydroxyethyl acrylate, hydroxypropyl acrylate and the corresponding methacrylic acid derivatives. Exemplified monomers for the non-cross-linking resins are vinyl acetate, ethyl acrylate, butyl acrylate, octyl acrylate, vinylidene chloride and copolymers thereof.  The composition may be dispersed as an aqueous emulsion, or dissolved in organic solvents and solvent mixtures.  Further ingredients such as melamine formaldehde resins and acidic catalysts may be present.ALSO:A pressure-sensitive adhesive tape comprises a flexible backing, such as a polyethylene terephthalate film, coated with a composition comprising a mixture of (a) a non-crosslinking polymer, and (b) a crosslinkable copolymer, said crosslinkable copolymer comprising the copolymer of the monomeric units of the polymer (a) and a crosslinkable comonomer.  A crosslinkable monomer is defined as one which when polymerized with one or more other monomers will result in the formation of a polymer containing a pendant reactive group which will self-crosslink. Crosslinkable monomers specified are N-methylol acrylamide, glycidyl acrylate. hydroxyethyl acrylate, hydroxypropyl acrylate and the corresponding methacrylic acid derivatives.  In an example, (a) is a vinyl acetate:octyl acrylate copolymer (50:50), and (b) is a vinyl acetate:octyl acrylate:N-methylol acrylamide (50:50:4) copolymer.

Title: Integrated assembly of circuit elements

IPC: H01L27/00
Filed: 1968-05-28
Abstract: 1,220,843. Integrated circuits. GENERAL ELECTRIC INFORMATION SYSTEMS ITALIA. 28 May, 1968 [30 May, 1967], No. 25487/68. Headings HlK and [Also in Division G4] The matrix of surface barrier diodes 7 shown is made from a silicon body la of low resistivity bearing a relatively resistive epitaxial layer lb The body is thermally oxidized and areas of the oxide over the epitaxial layer are removed to allow deposition of the gold surface barrier 5. Formation of the vertical conductors 4 (which lie on the oxide) is started by the vapour deposition of a pattern of Ni-Cr strips, upon which nickel is deposited without breaking the vacuum. An antioxidant layer of gold is then applied electrolytically and resistive bridges 6 of Ni-Cr are formed by vapour deposition. A thick layer of gold is then electrolytically deposited to complete the vertical conductors 4. Oxide is removed from the lower face of the body and a pattern of gold ohmic contact strips 2 applied-these function as a mask through which the body is etched to separate it into row strips which are held together by the vertical conductors 4. The matrix is converted to a read-only memory device by selectively energizing the conductors at power levels sufficient to burn out the resistive bridges 6 in the energized circuits. Such matrices may also be used in integrated logic circuits. Similar structures may be formed which include bipolar or field-effect transistors.

Abstract: 1476791 Stretched porous polymer films MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 7 June 1974 [11 June 1973 6 Feb 1974] 25489/74 Heading C3C Porous polymer films are made by the separate sequential steps of (a) forming voids in a stretchable polymer composition having a phase separation structure (i.e. in which the same or different compounds form two or more phases) and having the property of forming voids on deformation at a temperature below its m.p. (b) heating the polymer composition concontaining the voids to its stretching temperature (which is lower than the m.p. and higher than the temperature at which voids are formed on deformation) under tension of at least 0À1 Kg/mm<SP>2</SP> in one direction so that the voids do not disappear and (c) enlarging the voids by multi-axial stretching of the polymer composition at the stretching temperature. In the examples sheets of isotactic polypropylene which was connected to let crystalline particles grow high impact polystyrene (containing butadiene) and blends of polyethylene isotactic and atactic polypropylene nylon 6, polystyrene, ethylene vinyl acetate copolymer, polyethylene terephthalate, nylon 12, polyvinyl chloride, polyacetal and/or polycarbonate were cracked by bending along a bar in liquid nitrogen or at room temperature, by pressing a metal bar against the sheet placed on a rubber plate, by winding the sheet around a metal bar or by stretching the sheet by rolling between belts; the cracked sheets were then heated under tension and then stretched biaxially in one or two stages.

Abstract: 729,775. Electric motor driving arrangements. BENDIX AVIATION CORPORATION. Oct. 13, 1952 [Oct. 19, 1951], No. 25613/52. Class 35. [Also in Group XXXVII] A geared motor actuator for moving an output shaft 26 to a selected position comprises a motor 37 having a brake 71 and reduction gearing 25, cam operated switches 109 being controlled by the output shaft for effecting the appropriate energization and de-energization of the motor and its brake. The motor which is enclosed within a cover 10 comprises a field assembly 32 integrally connected to the endshield bearing supports 31, 33 by suitable spacing parts 34, 35. The field windings 38, 39 are retained in position by pairs of stiff, insulated conductors 40, 41 and 42, 43 respectively, one lead of each coil being connected to 40 and 41 and the remaining leads joined on 41. The lower ends of these stiff conductors are connected to the switch while the upper ends support the rocker clips 50 to which two carbon brushes 46, 47 are secured by plating and soldering and by a small boss 46a on the brushes extending through apertures in the clips to secure the connection. Pressure is applied to each brush by a torsion spring 52 carried by insulating tubes on the ends of retaining screws 54. The apertures for the rotor ball-bearings 60 are bored out simultaneously and at the same diameter as the pole faces by a single tool so as to obtain an accurate positioning of the rotor. This enables a very small air-gap to be used. The pole windings 38, 39 are wound in opposite directions and are arranged in operation to be energized alternately for the different directions of rotation of the motor. The motor brake comprises a disc 80 which is slidably splined on to the motor shaft and biased into frictional engagement with the end-shield 70a by a spring 83. Motor current passing through coil 88 lifts the disc 80 and allows rotation of the armature. The switching unit 11 comprises two pairs of spring contact arms 90, 91 and 92, 93 connected to the stiff conductors 40, 42 and actuated by cams 28, 29 on the load shaft 26 (see Group XXXVII). As shown in the operating circuit, Fig. 9, the supply from source 115 is controlled by switch 116. In the neutral position shown, current passes to contacts 105, 106 thus causing the rotor to run in such a direction that both contacts are open and then-to stop. Movement of the switch 116 to either extreme position energizes contact 107 or 108 to cause the motor to move into the required position at which point the cam 28 opens the switch 92 or 93. The block 109 having' the stationary contacts also carries permanent magnets 112 which attract the spring arms to produce a snap action.
