C 10-14  Monochloroparaffins are obtained by a liquid-phase non-catalytic chlorination process in which C 10-14  n-paraffins are reacted at 100‹ to 150‹ C. with mixtures of chlorine-containing gases obtained by the oxidation of hydrogen chloride with molecular oxygen at elevated temperature in the absence of paraffinic hydrocarbons. The n-paraffins and chlorine-containing gases may be fed to the base of a reactor and the gases from the reactor may be separated from the liquid at the top of the reactor and passed over zeolites to effect co-adsorption of paraffins and water, hydrogen chloride being recycled to the oxidation reactor.

[Class 39 (i)] [Also in Group XX] Relates to a method of reproducing drawings in which a fluorescent layer coated on a rigid backing sheet as of steel is coveted, with an opaque lacquer layer which is scribed through to produce the drawing, whereafter the fluorescent layer is excited ias by X rays or visible light, and a contact copy is made on a light-sensitive sheet. According to the invention, in order to prevent the scribing tool from damaging the fluorescent layer, the fluorescent medium is incorporated in a vehicle as of hard enamel which resists the tool, or is overcoated with a transparent layer having similar resistance. The fluorescent layer may comprise barium chlorofluride in a vehicle of modified alkyd and melamine resin and may be sprayed, on over an oil-type priming layer. The scribable overcoat may be of pigmented lacquer containing beeswax to facilitate scribing and a pigment such as lead chromate to reduce fog by absorbing unwanted X-radiation if X rays are used for the excitation. If a transparent layer is interposed between the fluorescent layer and the scribable layer, the vehicle of the fluorescent layer may be of the known nitrocellulose lacquer, and the transparent layer may be of hard clean lacquer formed as by coating half-second cotton solution.

Title: Improvements in and relating to resinous compositions and method of making
IPC: C08G63/127
Filed: 1925-06-13
Abstract: The complex ester resins, produced by the interaction of a polyhydric alcohol such as glycerine and a polybasic acid such as phthalic acid or its anhydride, are blended with a glyceryl ester of a fatty acid such as a drying oil for the purpose of making a japan base or varnish, for example for coating wires, by heating them in the presence of a common non-volatile solvent.  After the dispersion the solvent may be removed and the resulting viscous mixture used as such or dissolved in a volatile solvent. Specified oils for incorporation are drying oils such as china wood oil or linseed or perilla oil, and semi-drying oils such as soya bean oil, cotton-seed oil, or castor oil; non-drying oils may also be used.  Suitable non-volatile solvents are benzyl benzoate, benzyl acetate, nitrobenzene, toluidine, benzyl alcohol, cresol, aniline, glycol diacetate, phenylhydrazine and o-cresyl benzoate. In an example "glyptal" preferably in the fusible state is heated with china wood oil and benzyl benzoate to about 200 DEG  C. and the solvent afterwards removed.  The resin-oil blend may then be dissolved, in solvent naptha for example for application as a varnish.  The resin during the process of heating undergoes a partial "curing," as described in Specification 235,589.  The resinous compositions obtained may also be mixed with fillers and hardened by heat.  Specification 22544/13 also is referred to.

Abstract: A non-specific substantially non-toxic immunogenic agent adapted for use in stimulating non-specific immunity is obtained by incompletely acylating under substantially anhydrous conditions a pyrogenic lipopolysaccharide endotoxin extracted from a bacterial endotoxin-producing source microorganism, cooling the reaction-mixture to form a precipitate, separating the precipitate from the residual liquid, treating the precipitate with a pyrogen-free aqueous medium to form a fine suspension and precipitate, separating the precipitate, washing the precipitate with pyrogen-free water and recovering the immunogenic agent from the washed precipitate.  Acylation may be carried out at 80-120 DEG C. by means of acetic anhydride or benzoyl chloride.  A preferred endotoxin is a trichloroacetic acid extract of Salmonella typhosa.  Other microorganisms may be used e.g. E. coli, Pseudomonas aeruginosa, Serratia marscens, Brucella abortus, Shigella dysenteriae, Hemophilus pertussis, S. aureus and M. tuberculosis.  The immunogenic agent may be admixed with sulphonamides and antibiotics, e.g. penicillin and streptomycin.
