Abstract: 1304647 Cephalosporins TAKEDA YAKUHIN KOGYO KK [trading as TAKEDA CHEMICAL INDUSTRIES Ltd] 28 July 1971 [10 Nov 1970] 35510/71 Addition to 1300692 Heading C2A Novel cephalosporin derivatives of Formula wherein R is hydrogen or an acyl group and X is hydrogen or halogen, and salts thereof, are prepared by reacting a compound of Formula or a, salt thereof, with a compound of Formula or a salt thereof, R and X being as previously defined. Alternatively the inventive compounds wherein R is H may be prepared by deacylating the corresponding compound in which R is acyl, and vice versa. The preferred acyl groups R are represented by the formula R<SP>1</SP>R<SP>2</SP>CHCO- wherein R<SP>1</SP> is phenyl, phenoxy, cyclohexenyl, thienyl or 3-amino-3-carboxypropyl and R<SP>2</SP> is H or an amino group. The reaction between compounds (II) and (III) is usually conducted in water or a polar organic solvent. De-acylation of acylamino comounds to compounds wherein R is H may be effected by treatment with an imide halide-forming agent followed by conversion to the imino-ether and hydrolysis or alcoholysis; or when the acyl group contains a free amino group, deacylation by nitrosating this group followed by hydrolysis. The resulting 7-amino compounds of Formula (I) may then be re-acylated with a desired acyl group using a conventional N-acylating derivative of an appropriate carboxylic acid. Pharmaceutical compositions having broad spectrum antibiotic activity comprise a cephalosporin derivative of Formula (I) as defined above or a non-toxic salt thereof together with a pharmaceutically acceptable carrier or diluent.

Title: Process for cross-linking cellulosic-fibre containing materials  and products  thereof
IPC: D06M13/127
Filed: 1972-07-20
Abstract: 1403574 Cross-linking cellulosic fibres VAPORTECH Corp 20 July 1972 34031/72 Heading D1P [Also in Division C3] A process for cross-linking cellulosic fibres comprises depositing a solid polymer capable of thermal dissociation to yield a gaseous organic cellulosic fibre cross-linking agent on the cellulosic fibres, and heating the cellulosic fibres having the solid polymer deposited thereon to a temperature sufficient to thermally dissociate the deposited polymer in situ to yield the gaseous cross-linking agent which reacts with and cross-links the cellulose molecules making up the cellulosic fibres. The polymer is preferably a branched chain aldehyde polymer, which may be prepared by refluxing together a formaldehyde donor such as paraformaldehyde, and an aliphatic monocarboxylic acid (1-4C) such as acetic or formic acid and cooling the reaction mixture to effect precipitation of the polymer. The polymer may be deposited from the gas phase by maintaining the cellulosic fibres at a temperature between 0‹ and 95‹C. Alternatively the solid polymer may be deposited from a gaseous mixture of the aldehyde and carboxylic acid, the cellulosic fibres being maintained at a temperature at or below the polymerisation temperature of the polymer. The gaseous mixture may be generated by thermally dissociating an extraneous supply of the polymer. Alternatively the polymer may be deposited from aqueous suspension or a solvent system. The thermal dissociation is effected by heating the fibres after deposition to a temperature of 105‹ to 150‹C. Unreacted substances may be removed by flushing with an inert gas such as air. The process may be carried out batchwise or may be continuous and may be effected at, above, or below atmospheric pressure. The fibrous materials may be pre-treated with, e.g. emulsified polyethylene to enhance tear strength and abrasion resistance. For polymer deposition from the gas phase, the gaseous atmosphere may contain 20-60% by volume of gaseous polymer-forming chemicals and 80- 40% by volume of an inert gas such as air, nitrogen, carbon dioxide, aron or helium, and may have a moisture content of 4-16% by weight. Permanent press garments of woven, knitted or non-woven construction and flat, wrinkle-resistant woven or non-woven fabrics may be produced. The materials treated include 100% cottons, linens, rayons, paper, wood, etherified or esterified cellulosic fibre, and oxidised cellulosic fibre, and cotton-wool, cotton-polyester, and cotton-rayon blends. The materials may be in the form of fibres, yarns, woven, knitted or non-woven fabrics.

Title: Improvements in or relating to bonded materials
IPC: C08L67/00
Filed: 1929-11-08
Abstract: A resinoid binder and a filler particularly fabric are intimately incorporated together and during setting by heat the binder is given a reticulated structure by dispersing in it, before setting, a material which is liquid and insoluble in the binder or gaseous at the temperature of setting.  In various modifications of the invention the reticulated structure is obtained by (1) heating in the presence of a liquid such as water, which may contain hygroscopic substances, in which the binder is insoluble; (2) by volatization of a volatile solvent of the binder during setting; (3) by using a solution in the solvent of a material in which the binder is insoluble; (4) by dispersing in the binder before setting a volatile substance such as ammonium carbonate; or (5) by the use of a flexible resinous product immiscible with the binder such as a resin of the phenoltung oil type.  The term resinoid includes such as phenol, formaldehyde and phthalic anhydride-glycerol resins but does not include water-soluble salts of resins containing carboxylic acid groups. In one form of the invention, impregnated fabric is soaked in water until saturated and then subjected to heat and pressure.  A form of press which allows of any volatile ingredient being retained in the composition during pressing is described. Specifications 281,717 and 298,085, [both in Class 22, Cements &c.], are referred to.

Title: Method of coating an object having an elongated circular suface  particularly but not exclusively a pipe
IPC: F16L58/10
Filed: 1973-07-19
Abstract: 1414059 Forming protective coatings by winding HIELEMA EMMONS PIPE COATING Ltd 19 July 1973 [31 July 1972] 34378/73 Heading B8G [Also in Division F2] A method of forming a protective coating consisting of a thermoplastic resin and a resin compatible adhesive on an object having an elongated circular surface, e.g. a steel pipe 10, includes the steps of rotating the pipe 10 about its longitudinal axis whilst simultaneously advancing the pipe 10 longitudinally, extruding a sheet 22 of the adhesive on to the surface 12 of the pipe 10, thus forming helical windings 24 of the -adhesive on the pipe 10 and extruding a sheet 34 of the resin on to the adhesive covered pipe in sufficiently close proximity of time to the first extruding step to assure bonding of the helical windings 36 of the resin to the adhesive. The rates of rotation and longitudinal advancement of the pipe 10 are chosen such that (a) the distance advanced by the pipe 10 per revolution is no greater than one-half the width of the narrowest sheet, thus ensuring that at least two plies of each sheet is wound on to the pipe and (b) the speed of the surface of the pipe 10 due to its rotation is at least equal to and not more than 5% faster than the speed at which the resin sheet 34 is extruded. The extruders 20 and 32 are also positioned such that the lengths of the sheets 22, 34 before they contact the pipe are less than their widths. The pipe 10 is cleaned at a cleaning station 14 before the coatings are applied, the pipe 10 being at the temperature of the ambient air when the adhesive layer is applied. After coating the pipe 10 passes a cooling station 40. As described, the adhesive consists of a synthetic rubber composition and forms a two-ply layer 26 (Fig. 3), on the pipe 10 and the resin may be polyethylene, polyvinyl chloride or acrylonitrile-butadiene-styrene copolymer and forms a three-ply layer 38.
