Patent GB-449393-A (GB)
Title: A process of preparing improved wetting agents and detergents, and products thereof
IPC: C07C305/00
Filed: 1934-12-20
Abstract: Soaps produced from olefine mixtures, containing more than six carbon atoms in the molecule and obtained by cracking paraffin wax or petrolatum, by treatment with strong oxygen containing mineral acids and neutralizing are subjected to partial hydrolysis to remove the more readily decomposable component.  A stable product which does not develop acid when heated, e.g. in drying, milling and moulding processes is thus obtained.  The product is thus of greater utility in wetting and washing processes.  In an example, a fraction of a cracked petrolatum is treated with oleum and diluted with water while cooling.  The aqueous sulphuric acid is separated and the remainder treated with excess of alkali. Hydrolysis is then effected in the presence of isopropyl alcohol. On cooling, carbon dioxide is passed into the mixture which is then allowed to stand, when three layers are formed; the lower layer is discarded, the middle layer is evaporated to give a stable soap, and the top oily layer comprising alcohols and unattacked oils may be returned to the process.  Buffers and also alkalies may be added to the soaps before they are dried to ensure that no acid will be developed.  Hydroxides and carbonates of the alkalies, alkaline earths, ammonia, organic bases, e.g. hydroxyalkylamines, sodium acetate and sodium oleate may be added for this purpose.  The mixtures in the form of a spray may be dried by means of hot gases or a rotating drum drier may be used.  The Specification as open to inspection under Sect. 91 comprises also the subject-matter of the parent Specification as open to inspection. This subject-matter does not appear in the Specification as accepted.

Title: Improving the surface of plastic sheet material
IPC: B29C71/00
Filed: 1954-12-17
Abstract: <PICT:0759463/IV(a)/1> Sheet material of organic thermoplastic has its surface characteristics improved by immersing it in a bath of molten metal at a temperature sufficient to soften the material, at least superficially, but not to melt it.  The sheet is preferably drawn through a bath of the molten metal at such a level that the molten metal exerts a pressure of at least one atmosphere on the sheet, and is preferably drawn over and under rollers in the bath, so that both faces of the sheet contact the rollers. Smooth-surfaced rollers are preferably used, whereby a polished finish is imparted to the sheet, or they may have embossed or roughened surfaces to impart a patterned effect.  The rollers are conveniently carried on frames which may be lowered into the bath after threading up, or the bath may be raised or lowered by screw jacks.  The metal used is preferably mercury, thermostatically maintained at 325-400 DEG  F., but other suitable metals are lead, plumbers' solder, tin, white metal, bismuth amalgam, an eutectic alloy of tin, lead and cadmium, or germanium.  Suitable thermoplastic materials are organic substitution derivatives of cellulose, particularly esters, ethers or mixed ester-ethers: polyamides such as polyhexamethylene adipamide or the polymer of caprolactum; polyurethanes such as the reaction product of tetramethylene diamine with the bis-chloroformate of butanediol-1.4; polyesters such as polyethylene tetraphthalate; vinyl polymers and co-polymers.  Such materials may be formed into sheets by extrusion, rolling, or casting, after incorporating a plasticizer where necessary.  As shown, a cellulose acetate composition is extruded from die 11 at 400 DEG  F. as a continuous sheet 12.  The sheet is passed into a bath of mercury 13 maintained at 365 DEG  F. over smooth freely rotatable rollers 16, 17, 18 whose lower surfaces are 3 1/2 feet below the surface of the bath.  The sheet is drawn over guide roller 19, between cooling air jets 21 and is wound up by driven roller 22, at about 190 DEG  F.  The sheet is in the bath for about 1/2 minute.  The bath can be raised and lowered by screw jacks 15.

[Also in Divisions A5 and D1] A non-absorbable surgical suture having improved knotting characteristics comprises a polyfilamentous polyester strand having polytetrafluoroethylene (P.T.F.E.) both within the interstices thereof and on the surface thereof, the total amount of P.T.F.E. within the interstices and on the surface of the strand being not more than 4%, and preferably not more than 2%, by weight of the polyester. The polyester strand may be braided. As exemplified, the polyester is polyethylene terephthalate; other polyesters which may be used include those obtained from ethylene glycol or cyclohexane dimethanol and both isophthalic and terephthalic acids. The sutures may be sterilized by known techniques, for example by autoclave ethylene oxide or by electromagnetic radiation. To obtain the treated suture, the polyfilamentous polyester may be contacted with an aqueous dispersion of P.T.F.E. and then dried. Before drying, the suture may be washed to remove excess particulate material; after drying, the suture may be hot-stretched by any desired amount up to the breaking point, for example by up to 50% of the original length, by known methods at platen temperatures ranging up to the "sticking" temperature of the polyester. The P.T.F.E. dispersion preferably is below 50% by weight solids, advantageously below 20% by weight solids; such a dispersion may be prepared by dilution of a more concentrated P.T.F.E. blend, a wetting agent being used to assist dispersion of the P.T.F.E. particles. In the example, an aqueous dispersion, prepared by tenfold dilution of a commercial material containing 58% by weight P.T.F.E. having a particle size of half a micron, is used to treat a polyethylene terephthalate suture which thereafter is stretched, at a temperature of 450‹ F., by 40% based on its original length.
