Patent GB-1235894-A (GB)
Title: Method of migration imaging
Inventor: GOFFE WILLIAM LOCKE
IPC: G03G17/10
Filed: 1968-04-26
Abstract: 1,235,894. Detormation imaging. XEROX CORP. April 26, 1968, No.19967/68. Heading G2H. A surface deformation imaging structure comprises a supporting substrate overlaid with a softenable binder containing a hanogeneous disperson of photo-sensitive particles. The structure is uniformly charged, imagewise exposed to an original to form a latent electrostatic image, and developed by exposure to a solvent or its vapour, or by heat, whereupon photo-sensitive particles migrate to the substrate and adhere thereto in image configuration, the softenable layer and remaining photo-sensitive material being washed away. The substrate may be conductive, e.g., a metal or conductively coated plastic and conventional corona charging employed, or non- conductive, in which case the structure is charged whilst in contact with an earthed plate or is oppositely charged on its two sides. The softenable layer may be, e.g., a hydrogenated rosin ester, an alkyd, expoxy or silicone resin, or a copolymer, of e.g. methyl styrene and vinyl tolvene or styrene and hexylmethacrylate. The photo-sensitive particles may be inorganic e.g. selenium, or an organic pigment, the 'x' form of metal free phthalocyanine being preferred. The developer solvent, which must be insulating, may be e.g. xylene, dioxane, benzene, toluene or cyclohexane. Many examples are given of imaging plate preparation and a variety of charging, exposing and developing conditions are described. The image may be fixed on the substrate, during or after development, e.g. by softening the substrate and embedding the photo-sensitive particles therein, or by overcoating the image with a clear plastics film. In a modification, the photo-sensitive particles are replaced by non-photo-sensitive particles, e. g. carbon black, garnet, iron oxide and insoluble dyes.

Title: Production of elemental phosphorous and ferrous chloride
IPC: C01G49/10
Filed: 1956-06-28
Abstract: Phosphorus and ferrous chloride are obtained by the incomplete chlorination of ferrophosphorus at temperatures between 500 DEG  and 700 DEG  C. at atmospheric pressure, with corresponding temperature variations for super- or sub-atmospheric pressures.  The reaction is preferably carried out in an elongated inclined reactor. Chlorinating agents specified are chlorine, phosphorus tri- and penta-chlorides and the complex (FECl3)2PCl5, which is a product of the complete chlorination of ferrophosphorus.  The chlorinating agents are conveniently added in the vapour state.  The phosphorus is removed as formed, and the ferrous chloride is either drained off as formed by conducting the reaction above 670 DEG  C. or, the residue may after the reaction be heated to above 670 DEG  C. and the ferrous chloride then drained off. Specification 805,153 is referred to.

Filed: 1939-07-10
Abstract: 531,033. Cracking and refining hydrocarbons. STEVENS, A. H. (Gray Processes Corporation). July 10, 1939, No. 20052. [Classes 1 (i), 32 and 91] Hydrocarbon vapours are treated to polymerize and remove gum forming and like constituents therefrom by passing the vapours into the centre of a body of fuller's earth or like contact material and causing the vapours to pass horizontally through the material to a plurality of points of withdrawal adjacent the periphery of the body. Consolidated masses of finely divided material are provided horizontally above and below the body of fuller's earth which are pervious to the liquids formed but restrict the flow of vapours in the horizontal direction. As shown 'in Fig. 1 the treatment vessel comprises a shell 1 with conical ends 1b, 1c in which the fuller's earth is supported on packed granulated material 6 through which the liquids formed are withdrawn and pass off through a pipe 1!1. The vapours are fed through a pipe 17 into a central perforated shell 2 which is covered with a wire mesh screen 3. The vapours flow horizontally through the fuller's earth and are withdrawn through perforations 4, also covered with wire mesh, to an annular space formed between a cylinder 18 and the walls 4 of the treatment vessel. In a modification, the withdrawal means comprise a series of perforated cylinders spaced round the sides of the treatment vessel. The vapours treated may be fractionated so as to contain fractions of higher boiling point than those required in the final product and the temperature of the treatment chamber is arranged so that these fractions are condensed as the vapours flow through the fuller's earth and are removed along with the polymers from which they may be separated by distillation. Treatment temperature of 240‹ to 400‹ F. and upwards are specified.
