Abstract: 792,862. Facsimile telegraphy; trnaslating from one code to another. EASTMAN KODAK CO. Nov. 29, 1954 [Nov. 30, 1953], No. 3736/56. Divided out of 792,861. Class 40 (3). Facsimile signals corresponding to vertical line-by-line scanning of a character made up of a 7 Î 5 dot rectangle are produced in response to a potential appearing on a selected lead 119, Fig. 2, by means of a network of crystal diodes which cause potentials to appear on appropriate ones of seven groups of five leads 127 corresponding to the configuration of the character. These potentials then condition over vertical leads 172 corresponding diodes 178, Fig. 1, arranged in a 7 Î 5 matrix, whereby in response to the application of further potentials in succession to five horizontal leads 161, normally non-conducting valves 139 are rendered conducting in appropriate combinations to pass signals over leads 170 corresponding line-by-line to the character. The network of diodes, Fig. 2, is arranged in three parts, a first 132 setting up the potentials on groups of leads 127 which are common to a number of characters (thus letters E, F, H, K, L, M, N, P, R and W cause potentials to appear via rectifiers 131 on leads corresponding to the left-hand vertical stroke), a second section 133 setting up the potentials not common to any character, and a third section 134 which interconnects the first two sections to produce a complete character. The arrangement forms part of an apparatus as described in Specification 792,861 arranged to respond to character-determining signals which are in a six-unit binary code. The code elements control the setting of six flip-flop circuits and a network of crystal diodes (of which a part is illustrated in Fig. 3, not shown) is employed to produce, in response to the flip-flop settings, a potential on the appropriate lead 119 corresponding to the character indicated by the code. Specification 711,498 also is referred to.

Abstract: 1384591 Production of polymer latices EXXON RESEARCH & ENG CO 27 Jan 1972 3913/72 Headings C3G and C3P  A latex in which the dispersed phase is a polymer or polymer composition is produced by (a) providing a flow of gas containing steam as an initial continuous phase; (b) providing a cement of a polymer or polymer composition in a waterimmiscible volatile organic solvent; (c) emulsifying together the cement and water in the presence of an emulsifier to form an unstable emulsion; (d) dispersing the emulsion into the flow of steam to vaporize the solvent so that the vapour and dispersion droplets form an aerosol of latex in said vapour; (e) adding additional emulsifier to the aerosol and (f) separating the latex from the vapour phase of the aerosol. In modifications (1) the additional emulsifier is added between stages (c) and (d); (2) the unstable emulsion of stage (c) is formed in two steps, in the first of which an unstable crude emulsion is formed and in the second of which the emulsion is reduced to an unstable fine emulsion and additional emulsifier may not be necessary; (3) the additional emulsifier is added after step (f) and before or after concentration of the latex yielded by step (f); (4) in step (d) the steam condensed is added to the discontinuous phase of the aerosol and then (i) part of the water content of the latex flow separated from the aerosol flow is vaporized to convert the latex flow into a flow of water vapour mixed with more concentrated latex, which flow is (ii) commingled with the aerosol flow of step (i) (the latter flow and/or the commingled flows may be subjected to coalescing stresses); (5) after step (b) an ethylenically unsaturated monomer is added to the polymer cement and subjected to polymerization in the presence of a free radical catalyst to yield a graft polymer cement which is then subjected to steps (c) and the subsequent steps; (6) an ethylenically unsaturated monomer is added to the latex produced in step (f) and graft polymerization is carred out. Examples are given in which latices are produced from cements of toluene containing ethylenepropylene copolymer, butyl rubber, ethylenepropylene-diene terpolymer, polyisoprene, polyisobutylene and butyl rubber grafted with acrylonitrile. In addition, a toluene/butyl rubber cement is converted into a latex and then grafted with 2-vinylpyridine and a toluene/ butyl rubber cement, optionally containing silica, is converted to latex form and grafted with 2-hydroxyethyl methacrylate, acrylonitrile or ethyleneglycol dimethacrylate.
