Abstract: 1,078,760. Fluidizing apparatus. SOCIETE INDUSTRIELLE D'EXPLOITATION DES MOYENS DE TRANSPORT " SIMOTRA ". Oct. 19, 1964 [Jan. 29, 1964; May 12, 1964], No. 42597/64. Headings B8A and B8E. Apparatus, which may take the form of a wagon, for the pneumatic handling of granulated materials having combined means for fluidization and ejection comprises staged porous elements 5 longitudinally set in a cylindrical tank 1 on each side of and inclined towards the lowest line of the cylinder, and a discharge orifice positioned on this line. Pressurized air fed via conduits 11, 12 to the porous surfaces 5 mounted on supports 4 fluidizes the material and directs it towards the bottom of the cylinder where further porous fluidizing surfaces longitudinally inclined, and below the bottom of the cylinder direct the material towards the discharge orifice. This orifice may be coupled to two discharge pipes, for discharge to either side of the tank. The pressurized air is also fed direct to the tank 1 to facilitate material discharging. Material is fed to the tank through hoods 3 and is prevented from stagnating in the tank ends by inclined plates which have an equal pressure applied to each side. A manually operated flap (16), Figs. 6, 7 (not shown) may be opened to permit gravitational discharge of the material. The tank 1 may be divided into a plurality of separate fluidizing and ejecting apparatus.

Abstract: Copolymers which may be block, of a compound of the formula CH2=CHR and a compound of the formula <FORM:1033283/C3/1> where R represents a hydrogen atom, or an alkyl, aryl, or alkaryl group, Ar an aromatic radical, and R1 represents an alkyl group, an alicyclic ring or an aromatic radical, in which the aromatic radical or radicals may be unsubstituted or substituted by one or more alkyl, cycloalkyl, aryl, alkoxy, aryloxy, or dialkylamino radicals or halogen atoms or wherein the <FORM:1033283/C3/2> represents a polycyclic heterocyclic radical containing only one hetero atom and at least one carbocyclic aromatic ring, and where n is an integer in the range of 1 to 12, are made by copolymerizing the monomers in the presence of a catalyst comprising titanium tetrahalide an aluminium trialkyl and/or an aluminium alkyl halide.  The copolymerization may be carried out by introducing the monomers together or sequentially to the polymerization zone, and the reaction may be effected in bulk, or in the presence of diluent.  The titanium tetrahalide is preferably reduced to the trivalent form either by treatment with an organoaluminium compound, or reduction by hydrogen.  The copolymers are recovered by conventional techniques, e.g. addition of n-butanol. The copolymers may be fractionated by treatment with n-hexane, methanol, and acetone.  Exemplified copolymers are propylene, or ethylene, and N-methyl-N-undecenyl aniline, propylene and N-methyl-N-butenyl aniline, or N-methyl-N-pentenyl aniline, or N-ethyl-N-butenyl dimethyl aminoaniline, or N-phenyl-N-butenyl-beta-naphthyl amine, or N-methyl - N - pentenyl - alpha - naphthyl amine, or N-alkyl carbazole, or N-butenyl indole, and block copolymers of propylene and N-methyl-N-undecenyl aniline.

Title: Electrophotographic method for preparing planographic printing plates
Inventor: FIERENS JOSEPHUS JULIUS
IPC: G03G9/12
Filed: 1964-10-22
Abstract: 1,088,834. Electro-photographic processes for producing printing plates. GEVAERT-AGFA N.V. Oct.22, 1964, No.43223/64. Headings G2H and G2M. A hydrophobic photo-conductive surface is given a temporary or permanent hydrophilic character, in the configuration of an electrical latent image, by the imagewise or overall application of a liquid to it, after or during charging. Preferably, the liquid, applied overall, wets the charged areas, which it converts to a hydrophilic character, and is repelled from the uncharged areas. The liquid may, however, be deposited only in the charged areas, through the influence of the charge on a capillary applicator. Alternatively, the potential of charging electrodes can be varied to cause wetting in either the more conductive or less conductive parts of a latent conductivity image. The mere presence of an aqueous wetting liquid may be sufficient to repel lithographic ink from the non-image areas. Preferably, however, the liquid has a permanent hydrophilizing effect and is acidic to react with photo-conductive zinc oxide to form a hydrophilic precipitate. In the examples, photoconductive zinc oxide in a binder of polyvinylacetate or a copolymer of vinylacetate/laurate or vinylacetate/stearate is coated on a sheet aluminium or paper support. After treatment with liquid applied by means of a helically grooved roller Figs. 1 and 2 (not shown) the surface is contacted immediately with lithographic ink. The hydrophilizing liquids used include aqueous solutions of acid cupric chloride, hydrochloric and tannic acids, aluminium sulphate, ferric chloride, oxalic, tannic and phosphoric acids and potassium ferrocyanide. The following aqueous solutions are also referred to in this connection: ammonium and sodium phosphates, potassium ferricyanide and tartaric and fluorobutyric acids. Thickening agents used include: gum arabic, carboxymethyl cellulose, casein and polyvinylpyrrolidone. Other additives include dyes, surface active agents, water miscible solvents, soluble salts, hygroscopic salts and glycerine. Alternative binders for photo-conductive zinc oxide include polyvinyl butyral and silicone resins. The hydrophobic nature of the photoconductive surface may be increased by the application of a lithographic lacquer. A photo-conductive layer may be overcoated with a hydrophobic layer.

Title: Improvements in or relating to fuel injection pumps

Filed: 1963-11-05
Abstract: 1,029,189. Fluid-pressure servomotor systems. M.J. BERLYN. Nov 5,1963 [Jan 23, 1963],No.43699/63. Heading G3P. [Also in Divisions F1 and F2] A fuel injection pump comprises a piston 26 reciprocable and rotatable in the bore 27 of a cylinder block 28 by means of a cam 16 and gearing 15,21, driven by a shaft 11. The cam 16 acts on a follower 40 the motion of which is transmitted to the piston 26 through a rocker 39,47 which oscillates about a shaft 49 one end of which carries a piston 50, Fig. 3, and the other a spring loaded crosshead 51. The piston 50 is housed in a cylinder 52 subject to the pressure of fuel entering through a duct 80. The piston 50, shaft 49 and crosshead 51 constitute an injection timing servomotor 57. The piston 26 is provided with a distributor annulus 62,a distributor slot 63 and a spill annulus 61 which communicates with an axial spill duct 59 via radial ducts 60. The bore 27 is provided with annular recesses 74,75,76,discharge,supply and spill recesses respectively. The head of the bore 27 has counter bores 66 and 67 which house a valve 69 mounted on a piston 65. The lift of the valve 69 from the seat 68 may be adjusted by varying the thickness of a shim 72. Fuel from the discharge recess 74 passes through a delivery valve 86, Fig. 2, to the distributor annulus 62 and the distributor slot 63 which serves a plurality of discharge ducts 73,Fig.1,in succession. The recesses 75,76, and counterbores 66 and 67 are connected by ducts, Fig. 8,to the injection timing servomotor 57, a duct 84 leading back to the fuel supply and a fuel transfer pump 25, constituted by by the gearing 15,21, contained in a casing 24, Figs. 1 and 8. The injection timing servomotor 57 is responsive both to the quantity of fuel injected and the speed of the pump 25. The quantity of fuel injected will govern the timing of the operation of the valve 69. The smaller the quantity of fuel injected the later the valve operation and vice versa. The valve 69 permits communication between ducts 124 and 121 tending to lower the pressure in the duct 80 to retard injection. Increase in speed of the pump 25 increases the pressure of the fuel supply which is transmitted to the duct 80 through ducts 82 and 81 to advance the injection. For increased speed of rotation of the pump 25,for a given quantity of fuel injected, increased pressure in duct 82 results and thus the injection timing is automatically advanced. Adjustable constrictions 126 and 127 are provided in the ducts leading from duct 80 to recess 67 and pump 25.

Several alternative methods of product recovery are given: (1) removing the alcohol, ester by-product and catalyst by extraction with water, and either evaporating or steamdistilling; (2) adding additional alcohol to the reaction mixture, at reflux temperature, allowing the mixture to stand for a period, and then agitating to produce a rubbery crumb; or (3) adding further alcohol at reflux temperature to precipitate the product. Which method is used depends on the residual vinyl ester content of the product.
