Abstract: 547,494. Films etc.; synthetic resin compositions and articles. DU PONT DE NEMOURS & CO., E.I. Feb. 28, 1941, No. 2735. Convention date, March 2, 1940. [Classes 2 (ii) and 2 (iii)] A thin transparent film or sheet is made of a polyvinyl acetal resin plasticized with an octadecane-diol di-ester in an amount not exceeding about 30 per cent of the total weight of the film or sheet. The acetal resin may be a polyvinyl formal, butyral, iso-butyral, benzal, or acetal, or an interpolymer of different acetal forming radicals, or a mixture of polyvinyl acetals. Di-esters of octadecanediol-1 : 12 may be used. The di-ester may be formed from acetic, propionic, n- or iso-butyric, capric, caprylic, caproic, lauric, levulinic, glycollic, lactic, benzoic, benzoyl benzoic, chlorobenzoyl benzoic, hexahydrobenzoic, octahydrocinnamic, cyclohexyl acetic, furoic, or picolinic acid. The aliphatic groups in the acid. part of the ester may be branched or straight chain, substituted or not, and saturated or not. The ester may be formed from paraffinic or naphthenic acids obtained in the petroleum industry or from mixtures of acids corresponding to the higher alcohols obtained by the hydrogenation of oxides of carbon. The resin composition may be dissolved in a solvent such as methanol, acetone, ethyl formate, mixtures of methanol and benzene, or methyl acetate and methanol. The solutions may be formed into films or sheets by casting on to glass plates or polished nickel-surfaced drums. In examples, films are made from solutions of polyvinyl iso-butyral, polyvinyl benzal-butyral, polyvinyl formal, mixtures of polyvinyl butyral, isobutyral, and formal, and mixtures of polyvinyl formal, acetal, and butyral. These resins contain small proportions of hydroxyl and acetyl groups. The films are suitable for use as wrapping material or for making raincoats, capes, mittens, umbrellas, parasols, shower curtains, bridge-table covers, or tea-infusion bags. The material may be stitched or perforated without showing any marked tendency to tear. The Specification as open to inspection under Sect. 91 comprises also the use of di-esters of other glycols, e.g. tetradecanediol-7 : 8, dodecanediol-6 : 7, cetene glycol, and hexadecanediol- 1 : 2. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in inlaid linoleum
IPC: D06N7/00
Filed: 1929-01-28
Abstract: 305,628. Congoleum-Nairn, Inc., (Assignees of Clarke, A. E.). Feb. 8,1928, [Convention date]. Inlaid linoleum.-Inlaid linoleum is made bv assembling inlays of linoleum composition upon a plastic and adhesive base layer of composition, spaces being left between adjacent inlays, and consolidating the whole so as to embed the inlays partly in the base layer while maintaining the spaces between the inlays. The invention is particularly applicable to tile-pattern linoleum. A relatively thick layer 2, Fig. 1, of linoleum composition is applied to a backing 1 in the usual manner, its colour being chosen to represent the mortar between the tiles. The base layer may be partly cured or seasoned. The tile pattern is then formed by assembling blocks or tesserae 3, 4, cut from unseasoned sheets of composition, preferably of less thickness than the base layer. Spaces are left between the blocks to show the base layer. The linoleum is then subjected to heavy pressure to unite the tesserae with the base layer and to cause the edges 8 of the former to be rounded as shown in Fig. 3. Pressure may be applied by a smooth roll or by a ribbed roll or plate of which the ribs coincide with the channels or depressed parts of the finished linoleum.

Title: A process for the manufacture of pyridoxal phosphate
Inventor: LONG ROBERT FRANK
IPC: C07F9/58
Filed: 1954-02-03
Abstract: Pyridoxal phosphate is made by treating an aqueous solution of the alkali-metal salts of pyridoxamine phosphate and pyruvic acid, or a substituted pyruvic acid wherein the substituent may be an electrophilic radical or an alkyl, aryl or aralkyl group which may be substituted by an electrophilic radical, with a cupric, iron, nickel or cobalt salt which is soluble in water or in the reaction mixture, passing the reaction mixture through a cation exchange resin and eluting the pyridoxal phosphate therefrom with water. The reaction is preferably carried out in an inert atmosphere in the absence of light using proportions of from 1 to 2 mols. of pyruvic acid or substituted pyruvic acid to 1 mol. of pyridoxamine phosphate and 1/n mols. of the cupric, iron, nickel or cobalt salt (n being the number of atoms of the metal per mol. of the metal salt chosen).  Suitable electrophilic substituents which may be present on the pyruvic acid or alkyl, aryl or aralkyl pyruvic acid are for example carboxyl or acetyl groups. The completion of the reaction and the elution of the desired fraction from the cation exchange resin may be followed by measurement of the ultra-violet absorption spectrum.  In examples pyridoxamine phosphate is converted to pyridonal phosphate in aqueous alkali according to the invention by treatment with (1) pyruvic acid and cupric sulphate; (2) a -keto-glutaric acid and copper acetate; (3) a -keto-butyric acid and copper acetate; (4), (5) and (6) sodium pyruvate and copper acetate; (7) sodium pyruvate and ferric ammonium sulphate; (8) sodium pyruvate and cobalt nitrate; and (9) sodium pyruvate and nickel nitrate.

Filed: 1928-02-04
Abstract: 317,099. Taylor, A. M. Feb. 4, 1928, No Patent granted (Sealing fee not paid). Transmission conductor arrangements.-Long distance super-tension transmission between three-phase generating and consuming plant is effected through a two-phase transmission line and Scott-connected transformers, the trans mission line comprising four working cables, with or without spares, and switching arrangement whereby two transformer windings in 90 degrees phase relation and cables connected thereto may be associated with a cable connected to the neutral point for temporary transmission of the load in a quarter-phase system on failure of one of the cables, the cables being arranged in the ground in such a manner as to favour heat dissi pation at all times, and the arrangement being such that the magnetic fields of the cables or the electromotive forces induced in the lead sheaths are cancelled. Spare cables, normally connected to the neutral point, or a broken down cable may temporarily be used as a neutral conductor. Intersheath cables as described in Specification 264,196 may be used as main cables and spare cables. To reduce heating and cancel fields the cables are laid in pairs A, B, and C, D and the pairs well spaced, spare cables being also laid in pairs E, LT preferably between the others. Where the absence of telephone lines permits the cables may be laid separately and widely spaced, the lead sheaths being sectionalized and interconnected to cancel the sheath e.m.f. ; reactors may be arranged in the interconnections. The cancellation of cable fields may be effected through an additional insulated stranding of wires near the lead sheath these extra strandings being connected in a. closed loop whereby neutralizing currents may flow in them; armouring may be applied to such cables. To ensure a balance in cable currents after a breakdown series transformers ST may be arranged as in Fig. 3 with series connected secondaries or the cables may be re-connected, Fig. 4, where a spare low tension cable LT is provided so that it and the faulty cable B carry induced field cancelling currents assisted by the series transformers ST as shown. Where a low tension cable is connected to the neutral point a spark-gap in shunt to an earthing resistance, is used for protection. Where more than one spare cable is used the switching arrangements may make provision for succeeding breakdowns. Fig. 9 shows the interconnection of the sections of lead sheathings of two cables A, B and a spare cable E with reactors l in certain connections to prevent local circulation of sheath current whilst permitting any fault current to return readily bv the sheaths. An alternative method of sheath e.m.f. neutralization consists in cross-connecting core sections instead of sheath sections.
