Title: Improvements in and relating to emulsion polymerisation
IPC: C08F283/06
Filed: 1960-02-09
Abstract: 940,200. Emulsions of graft polymers. SHAWINIGAN RESINS CORPORATION. Feb. 9, 1960 [April 24, 1959], No. 4499/60. Heading C3G. A stable aqueous emulsion comprising solid water-insoluble polymer particles consisting of graft polymers of a vinyl ester with a polyoxyalkylene compound which is a block copolymer of ethylene oxide and propylene oxide, or the reaction product of an active hydrogen containing compound with an oxide having at least three carbon atoms and with ethylene oxide, is made by polymerizing the vinyl ester in an aqueous dispersion of the polyoxyalkylene compound in the presence of a water-soluble initiator by adding, after the polymerization has been initiated, successive amounts of both the vinyl ester and the polyoxyalkylene compound at such a rate that an emulsion viscosity of no more than 5,000 centipoises is maintained. Additional emulsifiers and stabilizers may be present in the initial dispersion. The vinyl ester may be vinyl acetate, propionate, butyrate, hexoate, or benzoate. The polyoxalkylene compounds which are the reaction product of active hydrogen containing compounds may be made by the methods disclosed in U.S.A. Specifications 2,674,619 and 2,677,700. The additional emulsifier is preferably a wetting agent containing a sulphonate group and at least one alkyl group. The water-soluble initiator may be a peroxy compound alone, or in admixture with a reducing agent. The additional stabilizer may be a cellulose derivative such as hydroxy-ethyl cellulose, a polyvinyl alcohol, a gum, or a starch. The stable aqueous emulsions are useful in coating applications e.g. as paints, paper coatings, over-print varnishes, wood finishes, floor waxes, and treating fabrics. They are also useful as bonding agents, and in the manufacture of films.

Title: Miniaturized electronic circuits and method of fabricating same
IPC: H01C7/00
Filed: 1962-02-06
Abstract: 999,689. Semi-conductor devices; circuit assemblies. TEXAS INSTRUMENTS Inc. Feb. 6, 1962 [Feb. 10, 1961], No. 4556/62. Headings H1K and H1R. The resistors in an electrical circuit are replaced by resistive paths in a uniform sheet or block of resistive material defined by electrodes attached to appropriately spaced points on the body. In one arrangement, Fig. 1, the resistors in a multivibrator circuit are constituted by the shaded portions of a sheet of resistive paper of 2000 ohms/square resistivity defined by the electrodes shown. Where the transistors and diodes of the circuit are small enough they may be mounted on the sheet to produce a more compact arrangement. Two resistive sheets of the type shown may be mounted end to end or may form two halves of a single sheet. In this case little interaction occurs between the two multivibrator circuits. Another possibility is for the resistive paths to be defined in a monocrystalline body in or on which the remaining components in the circuit are formed. Such an arrangement, shown in Fig. 5, is made by the following steps. An oxide layer is first formed on one face of a 5-10 ohm./cm. N-type silicon wafer, removed locally, and boron diffused into the thus exposed areas to form the P-type base zones of transistors 11, 12 and PN junctions of diodes 20, 23. The oxide is then removed from other areas and phosphorus diffused into these to form the transistor emitter zones and N + areas through which good ohmic connections may be made to the wafer. After applying aluminium by evaporation through a mask to form contacts where required, printed interconnections 52, 53 are formed by evaporating aluminium through a further mask. At the same time areas 32<SP>1</SP>, 37<SP>1</SP> are formed which, with the underlying oxide layer and wafer, constitute capacitors. The wafer thickness is then reduced by lapping the back surface. Capacitors 21, 24 are formed in situ by evaporation or are ceramic capacitors attached to the oxide layer. The remaining interconnections shown are made by gold wires thermally bonded to the wafer. In an alternative arrangement some of the connections are made to the back surface of the wafer.
