In the production of a printing plate using a dispersion of gelatine in carrier liquid as electrostatic latent image developing agent, the dispersion is produced by (a) dispersing a 1-20% aqueous solution of gelatine (optionally containing an alcohol in an amount insufficient to cause precipitation of the gelatine) in an organic solvent which is miscible with water but is a non-solvent for gelatine to form a dispersion of gelatine particles, (b) adding to the dispersion a solution of a resin which is insoluble in the organic solvent but soluble in the carrier liquid to form a coprecipitate of gelatine and resin, and (c) adding the co-precipitate to the carrier liquid. The proportion of solvent to gelatine solution may be 10-300. The organic solvent may be dimethyl or methyl ethyl ketone or ethyl alcohol. It may contain a vegetable oil or surface active agent. Dispersion in the organic solvent may be effected by ultrasonic or high-speed stirring. The resin may be polyisobutylene, polybutylene, polystyrene, styrene-butadiene copolymer, or a resinmodified phenol-formaldehyde resin. The resin solvent may be xylene, toluene, or methyl, ethyl or butyl acetate. The co-precipitate may be separated by decantation followed by centrifuging. The carrier liquid may be cyclohexane, kerosene, heptane, hexane or gasoline. It may contain a viscosity regulator or non-ionic surface active agent.

Title: Process for the manufacture of titanium dioxide pigments
Inventor: RICHMOND JAMES THOMSON
IPC: C01G23/08
Filed: 1956-02-21
Abstract: Titanium dioxide pigments are prepared by hydrolyzing an aqueous solution of a titanium salt to yield a hydrous titanium dioxide precipitate which is heated at a temperature not exceeding 800 DEG C, to remove water and other volatile matter, and the dry precipitate is calcined in a bed fluidized by a stream of hot non-reducing gas preferably at 600 to 900 DEG C.  The initial heating of the precipitate may be effected in a rotary kiln or alternatively the precipitated titanium dioxide, in aqueous suspension, may be spray dried in a current of hot gas, the gas for the heating stage preferably being the effluent gas from the calcination step.  The non-reducing hot gas is preferably obtained by the combustion of carbonaceous fuel with excess air and the fluidizing gas velocity is preferably between 0.5 and 5 f.p.s.  The hydrous oxide precipitates are preferably such as yield rutile on calcination, and a conditioning agent such as zinc oxide may be incorporated into the precipitate prior to calcination.  According to an example, a precipitate of hydrous titanium dioxide was prepared by hydrolysis of titanium sulphate solution in the presence of a nucleus liquid as described in Specification 623,813.  The precipitate was washed, filtered and the resulting pulp with a water content of 33% was mixed with 1% of zinc oxide and heated in a rotary kiln at 750 DEG C. in a current of hot gas.  The dried material was passed to a fluidized bed and calcined at 850 DEG C. in a current of gas produced by the combustion of fuel oil with excess air.  The process is compared with one where calcination was effected by heating a layer of titanium dioxide one inch thick in an electric furnace.

Abstract: Solvent-resistant polymers are produced by adding to an aqueous solution of an emulsifying agent 15 to 100 parts by weight of a butadiene (90-10%)-styrene (10-90%) copolymer in the form of a finished, i.e. "dead", latex, a catalyst, and 100 parts by weight of a mixture of butadiene, styrene and acrylonitrile or methacrylonitrile, and maintaining the resulting mixture at polymerization temperature until 90 to 100% of the added monomers has polymerized, the proportions of the monomers in the mixture being adjusted so that the resulting polymer contains between 10 and 40% of acrylonitrile or methacrylonitrile, 10 and 60% of styrene and 30 and 80% of butadiene.  Catalysts specified are alkali metal and ammonium persulphates, sodium perborate and hydrogen peroxide.  Also present during polymerization may be a mercaptan modifier.  The resulting graft polymers may be used in applications where solvent-resistance is required and also in the production of polymer dispersions in organic liquids as described in Specification 880,509.

The invention relates to a method of starting a gas turbine engine of the kind comprising a low pressure compressor and a high pressure compressor in series flow and driven by a low pressure turbine and a high pressure turbine respectively. The engine is started by means of a jet of air under pressure discharging into the air duct between the two compressors, the pressure air duct being located centrally within the air duct with its outlet nozzle passing through a valve disposed across the air duct and comprising a pair of flaps which when the starting air jet is operative are closed so as to prevent the back flow of pressure air introduced by the jet, and which when the engine starts are opened so as to allow air flow from the low pressure compressor to the high pressure compressor. In the embodiment shown air flows from the L.P. compressor, not shown, through the duct 1 to the H.P. compressor 2. The engine is started by means of air under pressure introduced into the duct 1 through a nozzle 3. A valve device comprising a pair of pivotally mounted flaps 5, 6 is disposed across the duct 1 at the outlet of the nozzle 3, the flaps being moved to the closed position indicated in chain dot lines by means of the actuators 9, 10 when the starting device is operative, and to the open position shown in full lines once the engine starts. The flaps are recessed at 7, 8 to permit engagement with the nozzle 3.

Abstract: 955,497. Moulding reinforced plastic products. COMPTOIR LINIER. Feb. 16, 1962 [March 14, 1961], No. 6161/62. Heading B5A. A process for moulding a reinforced plastic product comprises distributing a powdered incompletely condensed phenol-formaldehyde resin within a fleece or felt consisting predominantly of jute or flax fibres and moulding to the required shape whilst completing the condensation of the resin. Jute is chopped to a required length e.g. 2 to 5 cm., and is dried to a humidity of 4 to 6%, the fibres then being formed into a fleece. The fleece is sprinkled with a powdered incompletely condensed phenol-formaldehyde resin, and then converted to the form of a needlefelt, which is then cut into workpieces of the appropriate size and moulded in a heated press thus completing the condensation of the resin. Alternatively a fleece may be formed into a needle-felt, cut to the required size and one out of every two pieces formed sprinkled with resin, a second non-sprinkled piece placed on the first and the sandwich so obtained placed in a heated press to fuse the resin and then transferred to a heated moulding press to complete the condensation of the resin.
