Title: Surface curing of amine modified alkyd resins
IPC: B05D3/10
Filed: 1945-03-02
Abstract: The surface of a coating containing an amine-modified alkyd resin is cured with a solution containing a salt of a heavy metal, e.g. iron, cobalt, nickel, manganese, chromium, cadmium, aluminium, tin, copper, lead, zirconium, titanium, zinc, silver, antimony, vanadium, bismuth, mercury, tungsten, molybdenum.  The resin may be prepared from polyhydric alcohols such as glycerine, ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, hexaethylene glycol, decamethylene glycol, octadecandiol, trimethylene glycol, the butylene glycols, pentaerythritol, dipentaerythritol, sorbitol and dicarboxylic acids such as succinic, adipic, sebacic, phthalic, tetrahydrophthalic and azelaic.  The amine modifier is preferably an alkylolamine, such as monoethanolamine, diethanolamine, triethanolamine, ethyl monoethanolamine, phenyl monoethanolamine, the propanolamines and methanolethylene diamine.  Ethyl diethanolamine, aniline, methyl aniline, piperazine, pyridine, ethylene diamine, diethylene triamine, triethylene tetramine, tetraethylene pentamine, tetramethylene diamine, pentamethylene diamine, hexamethylene diamine or decamethylene diamine may be employed.  Further modification with monohydric alcohols, monocarboxylic acids or with hydroxy acids, fatty oil acids or their glycerides may be carried out.  Solvents for the heavy metal salt are preferably those having some solvent action on the coating and may be anhydrous or diluted with water, such as alcohols (e.g. methanol, propanols, butanols, amyl alcohols, cyclohexanol, benzyl alcohol), acetone, dioxan, ethyl acetate, a monomethyl ether of ethylene glycol or of diethylene glycol, hydrocarbons such as benzene, toluene, xylene and gasolene, but water with added wetting-agent is preferred. Fillers such as wood flour, walnut shell flour, a -cellulose, lithopone, red lead, zinc oxide, zinc yellow, asbestos or glass fibres and titanium dioxide may be employed.  In the examples: (1) a resin, prepared from diethylene glycol and sebacic acid modified with ethylmonoethanolamine and diethanolamine, asbestos fibre, wood flour and zinc yellow form a composition coated on an aluminium sheet, which is cured with a solution of 10 per cent aqueous ferric chloride and 50 per cent ethanol; (2) the same film as produced in example (1) is cured with 5 per cent aqueous ferric chloride solution containing 20 per cent ethanol; (3) 10 per cent ferric chloride in ethanol is employed; (4) 10 per cent ferric chloride and 0.5 per cent of the sodium salt of the dihexyl ester of sulphosuccinic acid is employed as the curing agent; (5) the curing agent is aqueous ferric ammonium oxalate with ethyl alcohol; (6) a composition of the resin of example (1) is treated as in any previous example; and (7) example (6) is repeated using an alcoholic solution of ferric chloride with added water as the curing solution.

Filed: 1916-04-11
Abstract: 100,276. Pons, V. April 14, 1915, [Convention date]. Spray carburettors.- The carburettor has a single control member which serves to maintain the proportion of air to fuel constant. The air passage 3 is controlled by a manually-actuated spring- loaded piston 14, with hemispherical end 18, which slides in a passage 4 of the same diameter as the passage 3. The nozzle 5 projects into the passage 3 to about its centre, the exterior surface 10 of the nozzle being of conical shape. The fuel passage 6 is reduced at 11 to form a spraying-orifice and is enlarged again to form a cavity 12, which serves the double purpose of holding a reserve supply of fuel and of preventing the force of the air current in the passage 3 from interfering with the discharge of fuel from the orifice 11. The piston 14 has a cylindrical cavity 19 which co-operates with the conical portion 10 of the nozzle to control the suction on, and therefore the flow of fuel from, the nozzle, simultaneously with the control of the passage 3 by the lower end of the piston. Cleaning of the nozzle and removal of the piston 14 are facilitated by the provision of caps 13, 17.

Filed: 1927-03-02
Abstract: 289,993. O'Brien, G. H., (Aspinall and Howell). March 2, 1927. Charge indicators.-A device for indicating by means of an external electrically operated indicator whether a storage battery is charged or discharged comprises two floats C', C<2> immersed in the electrolyte of the battery, the float C<1> rising when the battery is fully charged and the float C<2> sinking when the battery is discharged. For any intermediate condition of the battery the float C' rests on the bottom of the battery, the float C<2> remaining on the surface of the electrolyte. The floats carry contacts D<1>, D<2> by means of wires c<1>, c<2> which have loops c which by reason of the surface tension of the electrolyte cause the floats to rise and fall suddenly. The circuit through the external indicating circuit is completed by the contacts D<1>, D<2> through members E<1>, E<2> each of which consists of four segments connected diagonally in pairs, the two sets being provided with terminals e<1>, e<2>. One of the terminals e<1> is connected to the negative terminal a<1> of the battery, the other being connected to the terminal g<1> of a socket G for a three-point plug H. The terminals e<2> are connected respectively to the negative terminal a<1> of the battery and the socket terminal g<2>. The third terminal g<3> of the socket G is connected to the positive terminal a<2> of the battery. The plug H has three pins for the socket G and is connected to an indicating device K. When the battery is fully charged the float C' rises and completes the connection between the terminals e<1> and so makes the circuit through the socket g<1> and indicator K. When the battery is discharged the float c<2> falls and connects the terminals e<2> and completes the circuit through the indicator by way of the socket g<2>. The pointer of the instrument K moves in one direction or the other according as the circuit is completed through the socket g<1> or g<2>.
