Abstract: 972,932. Spinnerets for sheath and core filament production. BRITISH NYLON SPINNERS Ltd. Feb. 5, 1963 [Feb. 10, 1962], No. 5193/62. Heading B5B. A spinneret for the manufacture of sheath and core type of hetero or composite filaments comprises a plate having in the upper or inlet face thereof a bore and in the lower face thereof an extrusion orifice communicating with the bore, a hollow insert having in the lower end thereof an extrusion orifice, terminating above and out of contact with the extrusion orifice in the lower face of the plate, secured firmly in the bore, the lower portion of the insert being of smaller diameter than that of the bore to provide a space of annular cross-section around the lower portion of the insert, and a material supply duct communicating with this space. The hollow portion of the insert and the extrusion orifice are coaxial and the two axes are in the same vertical line. As shown in the drawing, a stainless steel plate A has a stepped bore B in which C is a locating shoulder and which terminates in an orifice D. The wall of the portion E of the bore B above the shoulder C is threaded to allow a hollow insert F, the upper portion of which is threaded and provided with a shoulder, to be screwed in and located in position on the shoulder C, the top of the insert F then being flush with the upper face of the plate A. The diameter of the lower end G of the insert F is smaller than that of the bore B, thus forming a space L of annular cross-section, which communicates with the material supply duct M, between the insert and the plate, the main body of the insert F being a close fit in the hole B. The hollow portion H of the insert F terminates in the orifice I, the axis of which lies on the same vertical line as that of the orifice D. Slot K is cut in the top of the insert to facilitate the removal and replacement of the insert. The orifices D and I are prefer. ably of equal diameter.

Filed: 1944-03-21
Abstract: 577,230. Transferring photographic emulsions. HART, J. A. H. March 21, 1944, No. 5213. (Class 98 (ii)] An emulsion is dry-transferred from a temporary to a permanent support by applying to the latter a water-insoluble organic colloid composition which dries or gels to a tacky layer containing at the most only a small proportion of volatile solvent, allowing the composition to. become tacky, pressing thereon the outermost organic colloid surface of a photographic element comprising a temporary support, a drystripping layer, an emulsion layer, and an adjacent layer of water-insoluble organic colloid, and dry-stripping away the temporary support. The temporary support (paper or film) may have a gelatine or other substratum, the stripping layer may be gum dammar or similar resin, and the water-insoluble organic colloid layer a cellulose nitrate or acetate or synthetic resin, preferably containing a plasticiser. The emulsion and colloid-layers may be transposed and the temporary support stripped prior to adhesion of the. colloid layer to the tacky layer. The water-insoluble colloid layer to be applied to the permanent support may be cellulose acetate or nitrate, which may be plasticised with triacetin, may be sprayed thereon, and may contain a white, black, or coloured pigment. The sensitive material may have a cellulose nitrate coating, which may contain triacetin, and the permanent support a coating containing polyvinyl acetate, a small proportion of cellulose nitrate, and triacetin. The permanent support may be wood or metal and may be later cut to form a template. In an example, paper is successively coated with gelatine, gum dammar, a silver halide emulsion layer, and a composition comprising cellulose nitrate, ethyl ether, and methyl alcohol, and an aluminium sheet with a composition comprising polyvinyl acetate, titanium dioxide, cellulose nitrate, triacetin, acetone, isopropyl alcohol, butyl alcohol, and butyl acetate or with a composition comprising a different polyvinyl acetate and omitting the isopropyl alcohol or with a composition comprising cellulose nitrate, tricresyl phosphate, triethyl phosphate, butyl alcohol, methyl isobutyl ketone, and methyl alcohol. After drying the cellulose nitrate surface of the sensitive material is pressed into contact with the tacky surface of the aluminium sheet and the paper stripped off. The emulsion may contain a plasticiser such as glycerol or a wetting agent such as sodium, ammonium, or triethanolamine salt of dodecylsulphuric acid. With plasticised emulsions, the stripping layer may be cellulose acetate, polystyrene, or polymerised methyl methacrylate. The plasticiser for the colloid coating may also be trimethyl or triethyl phosphate, diacetin, or p-toluene sulphonamide. The permanent support may also be of glass or plastic material. Specifications Nos. 554,292, 554,298, 554,300 and 554,301 are referred to.
