Abstract: 536,722. Vinyl polymerization products ; unsaturated acrylates. NORTON GRINDING WHEEL CO., Ltd. Aug. 22, 1939, No. 24140. Convention date, Aug. 27, 1938. [Class 2 (iii)] A resin, suitable for use in the manufacture of optical elements or abrasive bodies, is prepared by co-polymerizing vinyl methacrylate with methyl methacrylate, styrene or vinyl acetate. A further polymerizable substance adapted to modify the refractive index and/or dispersion value of the co-polymer may be present, e.g. acrylic or methacrylic acid esters of the hydroxy-quinolines, the nitrophenols, the chlorophenols and triphenylmethyl-carbinol, styrene, nitroethylene and o, m, and p-nitrostyrene. In examples, (1) vinyl methacrylate and methyl methacrylate are heated in the presence of a polymerization catalyst such as benzoyl peroxide ; (2) a grinding wheel is prepared by pouring a mixture of vinyl methacrylate, methyl methacrylate and benzoyl peroxide upon abrasive grain, e.g. aluminium oxide or silicon carbide, in a mould which is then heated to effect the polymerization ; and (3) a grinding wheel is prepared by mixing a finely divided co-polymer of vinyl methacrylate and methyl methacrylate, obtained either by grinding the solid copolymer or by polymerizing the monomers in solution in carbon tetrachloride in which the co-polymer is insoluble, with abrasive grain in a mould and submitting the mixture to heat and pressure. In making lenses, the co-polymer is formed in a two-part cylindrical mould, the resulting rod being cut into discs and ground to shape. Specification 512,806 is referred to. According to the Specification as open to inspection under Sect. 91, vinyl methacrylate is co-polymerized with any compatible substances containing a CH  2  = group. Vinyl acrylate, vinyl methacrylate and homologues thereof are prepared by the addition of acetylene or a substituted acetylene, e.g. allylene, to acrylic or methacrylic acid using a mercuric sulphate catalyst. Vinyl methacrylate may be alternatively prepared by the addition of methacryl chloride to acetaldehyde and dehydrohalogenation of the product, or by esterifying ethylene chlorohydrin with methacryl chloride and dehydrohalogenating the chloroester thus formed. This subjectmatter does not appear in the Specification as accepted.

Title: Process and apparatus for coating wire and the like
IPC: A46D1/00
Filed: 1962-06-28
Abstract: 992, 346. Coating wires &c. OSBORN MANUFACTURING CO. June 28, 1962 [Aug. 11, 1961], No. 24886/62. Headings D1L and D1P. A method of forming a beaded coating on wire, thread, synthetic filaments or composite bundles thereof comprises coating the wire or the like with a liquid which has a surface tension such that it forms into longitudinally spaced beads on the wire or the like, the beads then being solidified. In a preferred form the beads are substantially uniform in size and spacing. In Figs. 1 and 2 a plurality of wires from a roll 18, passes about a grooved roller 12a and is coated with primer liquid in a trough 20a which it enters through openings in a layer of closed cell polyurethane foam 22, acting as a seal. The primer coating is then doctored by a die 21a before having it solvent driven off by the passing of the wire through the electrically or steam coil heated chambers 13b, 13a. The wires then pass about rollers 11, 16, 17 and about grooved roller 12b before entering a second trough 20b (similar to trough 20a) to have coating liquid applied thereto; the thickness of the coating is regulated by dies 21b so that beads form on the wires before they enter chambers 13b, 13a in which the beads are solidified; the coated wires which are suitable for the bristles of rotary wire brushes, are wound on to a take up roll 19. In the above process the primer is preferably a solution of rubber in methyl ethyl ketone while the coating material is a plastisol comprising 100 parts of P.V.C. resin in 25 parts dioctyl phthalate and 25 parts dioctyl adipate with 3 parts cadmium 2-ethylhexanoate as a heat stabilizer. Other coating materials may be solutions or melts of phenol-formaldehyde resins, polyurethane resins or preferably thermoplastic resins e.g. vinyl resin, polystyrene resins, polyacrylate resins, nylon resins or linear polyesters. Particularly preferred coating materials are plastisols (i.e. a dispersion of fine particles of thermoplastic resins in a plasticizer) which form solid solutions on heating. In other fields molten metals, solutions of gums and certain waxes may constitute the coating material. Examples detailing the speed of wire advance, the temperatures of chambers 13a, 13b and the times taken for the wire to pass from die 21b to chamber 13 and to pass through chamber 13 are given. Details are also given of suitable diameters for the primer and coating dies for a range of wire gauges.

Title: Glass forming machine with automatic control system
IPC: D01H1/24
Filed: 1965-06-15
Abstract: A multiple operation glass forming machine, e.g. an I.S machine, has automatic control means comprising an electric signal source for generating a signal having a time span representing at least part of a multiple operation forming cycle, signal monitoring means arranged to respond to the generated signal and to generate control pulses indicative of a sequential series of pre-selected cycle times and means responsive to said control pulses for sequentially effecting changes in the forming operations of said machine.  As described, an electric signal from a pulse generator is fed into a pulse selector such as a counter. The counter, which may be a binary counter, contains hundreds, tens and units stages each having ten terminals. Selected terminals of each stage are connected to pulse selecting sections corresponding in number, i.e. 19 for an I.S. machine, to the number of operations to be controlled.  Each section includes an AND gate which emits a pulse when it receives three coincident pulses from the counter.  This emitted pulse is used to actuate the associated machine operation by means of an amplifier, solenoid and fluid energy valve.  The control system simplifies adjustments to the timing cycle, adjustments requiring merely the changing of the connections to the counter.  A single control means may control several machines.
