Title: Improvements in and relating to synthetic resins
IPC: C08G63/668
Filed: 1942-09-21
Abstract: Alkyd resins are modified with a b -furylacrylic acid or an esterifiable derivative thereof.  They may be further modified with fatty oils, particularly drying and semi-drying oils such as linseed and soya oils.  The products dry quickly, to very hard films.  A preferred method is to heat a drying oil with a polyhydric alcohol in the presence of an alcoholysis catalyst to form a partial polyhydric alcohol ester, and then to esterify this partial ester with a polybasic acid and a b -furylacrylic acid. The preferred b -furylacrylic acid is b -(2-furyl) acrylic acid, but other specified acids are a -methyl-b -(2-furyl)acrylic, a -cyano-b -(2-furyl) acrylic, a  : b  - di - (2 - furyl)acrylic, a -phenyl-b -(2 - furyl)acrylic, a  : b  - dimethyl - b  - (2 - furyl) acrylic, b -cyclohexyl - b  - (2 - furyl)acrylic, b -(3-furyl)acrylic, b -[2 - (5-methylfuryl)]acrylic, and b -[2- (5 - chlorofuryl)]acrylic acids. According to examples: (1) soya oil, glycerol and litharge are heated together, and phthalic anhydride and xylene are then added, and heating contined.  b -(2-Furyl)acrylic acid and further glycerol are added, and heating continued.  The resin is thinned with mineral spirits and a cobalt drier is added.  The solution dries quickly to a hard film; (2) linseed oil, glycerol and sodium hydroxide are heated together under a carbon dioxide blanket, and the product is mixed with more glycerol, phthalic anhydride, b -(2-furyl)acrylic acid and xylene, and heated further.  On the addition of a drier, a fast- and hard-drying clear coating composition is obtained; (5) soya oil, linseed oil, glycerol, mineral spirits and an aqueous solution of sodium hydroxide are heated together.  Phthalic anhydride, maleic anhydride and b -(2-furyl)acrylic acid are then added, and heating continued; (9) a resin prepared from coconut oil, glycerol, phthalic anhydride and b -(2-furyl)acrylic acid, is mixed with nitrocellulose, ethyl acetate, butanol, butyl acetate and toluene, to produce a lacquer drying to hard but flexible films.  Other examples are given, in which dehydrated castor oil, coconut oil, pentaerythritol, and adipic acid are specified starting materials.  Many alternative polyhydric alcohols and polycarboxylic acids are specified.  Other modifying agents which can be used include chinawood, cottonseed, oiticica, perilla, sunflower seed and corn oils; butyric, stearic, acrylic, oleic, glycollic, lactic, chloroacetic, benzoic, salicylic and rosin acids; butyl, n-dodecyl, allyl, benzyl and cyclohexyl alcohols; and the various synthetic oils which are described in Specification 569,404.  Coating compositions prepared from the resins of this invention may comprise driers, pigments such as barytes and titanium oxide, and solvents such as mineral spirits, toluene, butanol, butyl acetate, ethyl acetate and b -ethoxyethanol.

Abstract: 499,703. Plug cocks ; lubricating. HERVIEU, H. R. May 4, 1938, No. 13275. Convention date, Nov. 8, 1937. [Class 135] [Also in Group XXXIV] A lubricated plug cock is provided with an additional cylindrical stem i at the end opposite the usual operating stem g, the shoulders formed by the stems being such that the lubricant pressure acting on them partly balances the plug b axially. The two lubricant chambers n, o formed adjacent the shoulders are in communication by means of two diametrally opposed longitudinal channels p in the plug casing a which in the closed position of the cock connect with U-shaped channels formed in the plug surface so as to surround the ends of the through passage c with a frame of lubricant channels. Each U-shaped channel comprises a vertical groove q joined by two arcuate grooves r, r and in the open position of the cock is cut off from the lubricant supply pressure so that lubricant in the parts exposed at the casing ports e, f is not projected into the controlled stream of fluid. Each stem g, i has sealing grooves j. The upper stem g and if desired the lower stem i also passes through a gland h. The axial position of the plug is adjustable by a screw m. A safety device for cutting off the lubricant channels from the exterior when the lubricant is exhausted or when re-charging with lubricant comprises a spring-pressed piston s bearing a needle or other valve s<1> which closes the passage v<1> when the pressure in the reservoir v falls or the filling screw x<1> is removed. The piston carries also an indicating tail s<2> which projects to the exterior. The safety device may be designed as a separate fitting adapted to be connected to the grooves p or to either of the chambers n, o and its piston may have the filling screw mounted axially therein.

Title: Incandescent Lamp with Addition of Fluorine Compounds to the Gas Filling
IPC: C08F4/34
Filed: 1967-03-21
Abstract: 1,185,663. Coating with metals. DUROTEST CORP. March 21, 1967 [April 8, 1966], No. 13294/67. Heading C7F. [Also in Division H1] In an incandescent filament lamp containing a source of fluorine the ends of the filament, which in operation are cooler than the main central portion, are protected by a coating of fluorineresistant metal, preferably iridium, osmium or rhenium. The ends, which may first be reduced in diameter, can be coated by electrolytic deposition, vapour deposition or cathodic sputtering in a low pressure gas discharge. In an alternative method, the whole filament is coated with a thin layer of the metal, assembled in the lamp bulb together with an argon-nitrogen-nitrogen fluoride filling, and operated for between 30 seconds and 30 minutes. During this time the metal evaporates from the central portion of the filament at a faster rate than from the cooler ends, combines with the fluorine in the cooler parts of the bulb, and is redeposited on the filament as a result of thermal dissociation of the metal fluoride, the rate of deposition being substantially the same over the whole filament length. Consequently, the metal coating migrates to the filament ends where it is required.

Title: Process for the production of plastic-elastic compositions
IPC: C08L19/00
Filed: 1934-05-03
Abstract: A plastic composition comprising rubber and cumarone and/or indene resin is prepared by kneading together vulcanized rubber and the indene or cumarone at temperatures of 120-130 DEG  C. to form a homogeneous mass consisting of a solution of vulcanized rubber in the resin, and thereupon incorporating additional vulcanized rubber with the mixture; but taking care that the incorporation is carried on just long enough to complete the admixture but short of the mass becoming homogeneous.  Up to 50 per cent of the vulcanized rubber may be replaced by unvulcanized rubber, and a small amount of the indene or cumarone may be replaced by other resins such as colophony. Fillers such as wood flour, oils, factis and linoxyn may be added in small amount.  In an example 2 parts of old motor tyres are homogenized with 6 parts of cumarone resin and 1 part dried linseed oil at 140 DEG  C.  4 Parts of this mass are then further mixed with 4,3 parts chalk and 2,3 parts vulcanized rubber the second mixing being stopped before the mass becomes homogeneous.

Abstract: 801,604. Respiratory appliances. NORMCLAIR, Ltd. April 26, 1957 [May 3, 1956], No. 13689/56. Class 81 (2). In order to avoid loss of oxygen at low altitudes and to admit atmospheric air to an aircraft breathing mask when no oxygen is required a light, flap valve 16 is mounted on the regulator diaphragm 3. This has less flow resistance than the oxygen valve mechanism 12 and opens at low altitudes to pass air through ports 18 to pipe 7 and mask 6. At greater altitudes known mechanism operating on the diaphragm causes oxygen to be supplied at positive pressure, which causes the valve 16 to be held closed continuously. At such altitudes, oxygen passed by valve 11 operates in a venturi arrangement to draw air through an aneroidcontrolled valve 13 in accordance with the proportion necessary. In a second embodiment a non-return valve is fitted into a pipe leading into the flexible pipe 7, so that again air may be freely drawn in at low altitudes, but the valve is held closed by excess pressure at greater heights.
