Abstract: 1393558 Photographic development HOECHST AG 22 Dec 1972 [28 Dec 1971] 59331/72 Headings G2H and G2X Photo-sensitive material is developed by passing it into a bath of circulating developer liquid at a relatively static portion thereof and discharging it from the bath below the surface of the liquid through squeezing means which squeeze the material and substantially prevent developer from escaping from the bath. An apparatus for effecting the development has a pair of rollers for effecting the squeezing and an inclined bowed base element, the lower end of which is positioned close to the nip of the rollers, for supporting the material as it is transported through the bath. As shown an exposed electro-photographic printing plate 13 slides from a table 12 on which it has been held by a stop 11 between rollers 1, 2 which feed it into a bath 7 into which developer has been sprayed through orifices 8. The spraying causes circulation of the developer, but a baffle 6 provides a relatively static zone, into which the plate is inserted. The plate then passes through the developer over a supporting element 10 and ribs 15 and is then ejected by squeeze rollers 3, 4 on to table 17. Rollers 3, 4 substantially prevent escape of developer, but a bath 16 is provided for collecting any which does escape and also any developer from overflows (27) which control the developer level 14 in bath 7, this developer is then returned to supply tank (22) for recycling. The rollers may have roughed metal, glass, ceramic or elastomeric surfaces.

IPC: C08F16/12
Abstract: 763,635. Cellulose derivatives; artificial filaments &c. ROHM & HAAS CO. March 29, 1954 [April 10, 1953], No. 9093/54. Classes 2 (2) and 2 (6). [Also in Groups IV (b), IV (c), V, VI and VIII] Vinyl ethers of the formula and ureido derivatives thereof obtained by subsequent reaction with ammonia or amines, wherein Z is a methylene or polymethylene group optionally carrying hydrocarbon substituents and containing not more than seven carbon atoms, and R<SP>1</SP> and R<SP>11</SP> are alkyl groups when Z is such that O and N are separated by not more than 3 carbon atoms, and are hydrogen or alkyl groups when Z is such that O and N are separated by more than 3 carbon atoms, alone or admixed with one or more other monomers, are polymerized in bulk, aqueous emulsion or organic solution in the presence of a polymerization catalyst. Alternatively, the monomers may be reacted with natural or pre-formed synthetic polymers, e.g. cellulose, rayon, cotton, silk, wool, blood, polyamine resins, acrylic resins, alkyd resins and polyvinyl alcohol resins. Reaction products with blood may be further polymerized. The monomers may also be mixed with alkyd resins and a polyfunctional acid such as adipic acid and polymerized in presence of an acid catalyst. The other co-monomers may be acrylates (e.g. methyl, ethyl, propyl and butyl acrylates), methacrylates (e.g. methyl, ethyl, isopropyl, butyl, tert.-butyl, and tert.-amyl methacrylates), acrylonitrile, methacrylonitrile, acrylamides, methacrylamides, styrene, vinyl esters or mixtures thereof. In aqueous emulsion the emulsifier may be sodium octylphenoxyethoxyethoxyethyl sulphonate. Specified solvents are dimethylformamide and toluene. Exemplified vinyl ethers are 2-vinyloxy-4- methyl - 4 - pentylisocyanate, 2 - isocyanatoisobutyl vinyl ether and 2-ureidoisobutyl vinyl ether. The catalyst may be azodiisobutyronitrile; azodiisobutyramide; dimethyl, diethyl or dibutyl azodiisobutyrate; azobis- (α : γ - dimethylvaleronitrile); azobis - (α- methylbutyronitrile; azobis - (α - methylvaleronitrile) ; dimethyl or diethyl azobismethylvalerate; benzoyl, methylethylketone or caproyl peroxide; tert.-butyl hydroperoxide; butyl perbenzoate; or in aqueous systems ammonium, sodium or potassium persulphate in conjunction with sodium hydrosulphite. The above polymers may be after-treated with amines to yield polyureido derivatives. Thus, (1) a toluene solution of polymerized 2-isocyanatoisobutyl vinyl ether yields a gel on treatment with iminobispropylamine; (2) an acetone solution of polymerized 2-isocyanatoisobutyl vinyl ether yields a dimethylaminopropylurea derivative on treatment with dimethylaminopropylamine; and (3) a toluene solution of a 2-isocyanatoisobutyl vinyl ether/ methyl methacrylate copolymer increases in viscosity on treatment with iminobispropylamine. The above polymers, in particular polymerized 2-isocyanatoisobutyl vinyl ether, may be added to cellulose acetate dopes. Films or fibres formed from thus treated dopes possess improved tensile strength and are highly resistant to solvents' after heat treatment.
