Title: Polyacrylate compositions
Inventor: MURE WILLIAM SIDNEY
IPC: C08L27/06
Filed: 1964-04-10
Abstract: A composition comprises (A) a polyalkyl acrylate latex and (B) a polyvinyl chloride latex, the proportions by weight of the polymer content of A to that of B lying between 10:90 and 90:10. Alkyl acrylate units comprise at least 60% of the polymer of the polyalkyl acrylate latex, the remaining units being derived from a monomer other than butadiene, and vinyl chloride units comprise at least 60% of the polymer of the polyvinyl chloride latex. Specified polyacrylates are homopolymers of alkyl acrylates and copolymers of alkyl acrylates with e.g. methyl methacrylate, acrylonitrile, styrene or vinyl chloride.  The polyacrylate may contain units of a carboxylated monomer e.g. acrylic acid and may be heat reactive, i.e. it may contain monomers capable of reacting with themselves at elevated temperatures. Vinyl chloride polymers specified are homopolymers and copolymers with e.g. vinyl acetate, vinylidene chloride, methyl acrylate, ethyl acrylate and higher acrylate esters. Conventional P.V.C. plasticizers are used.  The compositions are used as paper saturants (see Division D2).  In examples latex (A) is a copolymer of ethyl acrylate, methyl methacrylate, N-methylolacrylamide and acrylic acid and latex (B) is polyvinyl chloride, or a vinyl chloride-ethyl acrylate copolymer plasticized with a phthalate ester of C7 to C9 alcohols.ALSO:Paper is saturated with a composition comprising a mixture of (A) a polyalkyl acrylate latex comprising at least 60% alkyl acrylate units, the other units being derived from a monomer other than butadiene, and (B) a polyvinyl chloride latex comprising at least 60% vinyl chloride units, the weight ratio of polymer (A) to polymer (B) being between 10:90 to 90:10.  In examples standard white base paper is saturated, latex (A) being a copolymer of ethyl acrylate, methyl methacrylate, N-methylolacrylamide and acrylic acid and latex (B) being polyvinyl chloride or a vinyl chloride-ethyl acrylate copolymer.

Title: Enameling of cast and sheet metal
IPC: C03C3/066
Filed: 1925-06-16
Abstract: 262,159. Gibaru, C. Totot-. June 16, 1925. Enamelling vitreous.-To eliminate the employment of a first layer of clear ground enamel when employing leadless glazes for enamelling metals by the dry method, an enamel is used having silica, borax or borate-forming substances, and at least 20 per cent of zinc oxide as essential ingredients. An example of an opaque white enamel to serve as a sole layer in the case of sanitary ware or as a first layer in the case of decorated or glazed ware is given as follows. Silica 22.5 per cent, alumina 3.5 per cent, lime 3.5 per cent, zinc oxide 23.5 per cent, soda 16.5 per cent, potash 2.5 per cent, oxide of antimony 12.5 per cent, boric anhydride 13.5 per cent, and fluorine 2 per cent. Each of the above ingredients of the mixture may be varied within the following limits. Silica from 2-25 per cent, zinc oxide from 20-35 per cent, hydrated borax from 35 to 70 per cent, alkaline nitrate from 2-20 per cent, alkaline fluorides from 0-8 per cent, carbonate of lime from 0-30 per cent. Additional substances may be added for colouring effects or for increasing the opacity as may be found necessary. This white enamel may be covered by a second layer or top glaze of colourless enamel comprising silica 15 per cent, alumina 1 per cent, lime 12.6 per cent, soda 18 per cent, zinc oxide 30 per cent, boric anhydride 21 per cent and fluorine 2.4 per cent. A table of widely-differing limits is also given for each constituent of this second enamel. Specifications 4610/79 and 5934/95, [both in Class 87. Moulding &c.], are referred to.

Title: Improvements in or relating to devices for scanning cinematograph films
IPC: H04N3/36
Filed: 1939-05-25
Abstract: 525,870. Television. PHILIPS LAMPS, Ltd. May 25, 1939, No. 15593. Convention date, May 28, 1938. [Class 40 (iii)] Relates to film scanning systems comprising a light source L, Fig. 1, a perforated scanning disc 3, a lens 6, and a rotating or oscillating mirror device 5 throwing a spot of light on the film 1, the light passing through the film to a photoelectric 7 directly or through a lens 17. In such a system, the position of the spot of light on the cell varies leading to variations of output due to local variations of sensitivity of the cell. To avoid this defect, the invention provides between the film and the cell two cylindrical lenses 9, 13, Fig. 2b. The cylindrical lens 13 forms an image g of each mirror 11 in the plane 14 of the photo-cathode of the cell. Similarly the cylindrical lens 9 forms a transverse image of the lens 6 in the same plane 14. Thus the light passing through the film is always uniformly distributed over the same part of the surface of the photo-cathode. The two cylindrical lenses may be replaced by an equivalent combination of spherical and cylindrical lenses or by a spherocylindrical or sphero-torical lens. In a modification, the positions of the light source L and photo-cell 7 are interchanged.

Title: Squrrel cage rotor electrical machines
IPC: H02K9/02
Filed: 1976-04-15
Abstract: In the case of asynchronous machines having a double squirrel-cage rotor, the problem of good dissipation of the heat losses is solved in that some of the operating bars (7, 7b, 7c) are lengthened and are electrically conductively connected to air guide rings (9). Furthermore, the starting bars (7a) are electrically conductively connected to either the operating bars or to rings (8, 15), the successive starting bars being arranged symmetrically between the operating bars. The rotor electrical resistance in the transverse direction is increased. As a result of these measures, it is possible to dispense with an internal fan. This construction allows good heat dissipation and an increase in power with a simple design. <IMAGE>
