IPC: C08G77/445
Filed: 1955-03-24
Abstract: A silicone-alkyd resin consists essentially of the reaction product of (1) 5 to 60 per cent (by weight) of an organosilicon compound of the general formula RnSiXmO4-n-m/2, wherein each R is a monovalent hydrocarbon or halogenated hydrocarbon radical, each X is a halogen atom, alkoxy or hydroxy radical, n has an average value of 1 to 2 and m has an average value of 0.05 to 3; (2) 10 to 35 per cent of alcohol composed of 20 to 100 per cent by weight, calculated on the total alcohol content, of trimethylolethane, 0 to 50 per cent of a dihydric alcohol and 0 to 30 per cent of another trihydric alcohol; and (3) 20 to 60 per cent of a dicarboxylic acid, anhydride or lower alkyl ester (i.e. containing less than 9 carbon atoms) thereof.  The preferred method of making the resins comprises the single stage reaction of (1) 5 to 60 per cent of the organosilicon compound, (2) 10 to 35 per cent of alcohol composed of 50 to 100 per cent of trimethylolethane and 0 to 50 per cent of a dihydric alcohol, and (3) 20 to 60 per cent of a lower alkyl ester of a dicarboxylic acid, at 100 DEG  to 250 DEG C. until the desired viscosity is obtained.  The reaction may be effected in the presence of a catalyst such as magnesium acetate or perfluoroglutaric acid.  Reactants specified are: (1) dimethyldichloro-, dibutyldi-isopropoxy-, phenylmethyldichloro, divinyldibutoxy-, tolyltriethoxy, cyclohexyl-trimethoxy-, phenylmethyldibromo-, (trifluoromethylphenyl) methyldichloro-, chlorophenyltriethoxy-, bromoxenyltrichloro-, stearylmethyldiethoxy and allylstearyloxydimethoxy-silanes, mixtures and hydrolysates thereof, diphenyl-, phenylmethyl-, dimethyl-, chlorophenylmethyl- and octadecylmethyl-silanediols; (2) ethylene glycol, neopentylglycol and glycerine; (3) malonic, adipic, maleic, dimethylmaleic, cyclohexyldicarboxylic, phthalic, terephthalic, isophthalic, naphthalic, stilbene dicarboxylic, diphenic, tolane dicarboxylic and dibenzyl dicarboxylic acids, their anhydrides and alkyl esters containing less than 9 carbon atoms.  In a modification up to 50 per cent of (1) may be replaced by a drying oil and/or drying oil acid, e.g. linseed, sardine, soyabean, dehydrated castor, tung, oiticica, perilla, chinawood, hemp seed, poppy seed, safflower, sunflower or walnut oil or acid derived therefrom.  The resins may be dissolved in solvents such as acetonyl alcohol, naphtha, isophorone or cresylic acid or solvent mixtures such as diacetone alcohol and butyrolactone; petroleum hydrocarbons, isophorone and methylamylacetate; acetonyl acetone and diacetone alcohol; and C6H5.OCH2.CH2.OOC.CH3 and diacetone alcohol, and used for coating metal surfaces, particularly fine wire.

Abstract: 610,346. Temperature-responsive actuating-elements. NEWTON, E. P. (Telefonaktiebolaget L. M. Ericsson.). March 15, 1946, No. 8178. [Class 64(ii)] A thermo - contact more especially for f i r e installations, comprises two bimetallic strips fastened at one end to a base or the like, and soldered together at their other -ends by an easily fusible alloy, said strips when so soldered being entirely on opposite sides of a dividing plane passing through the soldering point and perpendicular to the main limbs of the strips. The strips 1, joined by solder 3 are mounted on base 2 so as to have only a small tendency to separate. This tendency increases with rise in temperature until the melting point of the solder is reached, when the strips move to the positions shown in dotted lines and contact is broken. In a modification. Figs. 2, 3 (not shown), the plane of the strips is perpendicular to that of the base. In a further modification, Figs. 5-7 (not shown), the planes of the strips when soldered together form an angle with each other. The strips may be soldered without first being bent at the ends, and they may also be mounted so as to flex in the same direction on heating.

Title: Improvements in or relating to the production of aluminium chloride
Inventor: DERHAM LESLIE JACK
IPC: C01F7/58
Filed: 1962-03-07
Abstract: In the production of aluminium chloride, a molten zinc-aluminium alloy is treated with a stream of chlorine gas, aluminium chloride vapour is formed and substantially pure, e.g. 98-98.5% pure, zinc metal is recovered.  Suitable apparatus is described and claimed in Specification 1,035,808.ALSO:Anhydrous aluminium chloride of 99% purity is prepared by passing chlorine gas into a molten zinc-aluminium alloy, preferably at 430-500 DEG  C.  The AlCl3 vapour produced may be passed through a layer of aluminium pieces maintained at 200 DEG  C. to remove residual free chlorine, and then withdrawn as vapour or condensed to the solid.  Massive or crystalline aluminium chloride may then be produced by heating the solid to 200 DEG  C. under pressure (e.g. 2.5 atm.) and solidifying, or by sublimation and recondensation.  A suitable alloy comprises zinc and aluminium in the ratio 9: 1. Apparatus for preparing aluminium chloride by this method is described and claimed in Specification 1,035,808.

Abstract: 442,056. Exhaust and like silencers. BURGESS LABORATORIES, Inc., C. F., Madison, Wisconsin, U.S.A. March 25, 1935, No. 9264. Convention date, March 24, 1934. [Class 7 (ii)] In apparatus for silencing gaseous currents in the intake or exhaust conduits of internalcombustion engines, compressors, &c., the conduits are connected to a perforated manifold arranged within a casing so as to form spaces between the manifold and casing which comprise means for attenuating the gaseous pressure waves. Fig. 1 shows a silencer comprising a casing 1 in which is secured a perforated shell 5 with sound-deadening filling in the space 11 formed between the shell and casing, the shell communicating with the engine &c. ports by conduits 8, and with the inlet or exhaust pipe at 10. In the case of exhaust silencers, the connections 91 between the shell and casing are arranged to allow free expansion of the former. The casing may be rectangular, circular, or of irregular shape in cross section. The shell may be made in sections, the portions opposite the ports 8 being thicker than the others and also imperforate, to offer more resistance to the heat of the exhaust gases. The filling 11 may be cotton, wool, felt, wood fibre, &c., or for internalcombustion engine exhausts, metallic or rock wool, asbestos, vermiculite, pumice, Haydite, &c. Fig. 8 shows another silencer with resonator chambers formed by the casing 40, perforated shell 47, partitions 51, 54, 55, and perforated pipes 59 leading to the engine &c. ports. An air filter 65 is shown connected to the inlet 45. The space 50 may be filled with absorbing-material. The size of the openings 62 in the pipes 59 is such that these attenuate waves of low frequency, while the other chambers attenuate the higher frequencies. Fig. 11 shows conduits 71 leading into a manifold 70 fitted with a silencer casing 73 provided with perforated partitions 79 and absorbent filling 80.

[Class 132 (ii).] A racket for use in playing a tip-cat game comprises a frame having a slightly curved or straight side a forming a continuation of the racket handle and a substantially curved or semicircular side c, the frame so formed being strung with gut or the like after the manner of a tennis racket, and a projecting finger or nose e in substantial alignment with the handle for tipping the tip-cat into the air. The tip-cat may consist of a hollow piece of cork g, Fig. 5, plugged by pointed cork ends h which may be forced in to compress the entrapped air and thus give resiliency. A protective coat of enamel is applied or polished shields are affixed thereto. The tip-cat may be made in one piece of hollow celluloid, rubber, compressed cork or other light material. When made of rubber the contained air may be under pressure. The tip-cat may be built up of cork containing an inflated rubber bag. In Fig. 9 is shown a device, in the form of a thistle, for projecting the tip-cat into the air preparatory to being struck by the racket. The device comprises a helical spring l enclosed between a rubber cover k and a loose cone r. The cone rests on the domed top of a sliding collar s bearing on a pair of weighted clutch arms l. A plunger p when depressed by the player compresses the spring and is retained in the lower position by the clutch arms. The tip-cat is placed on the top of the device and is projected upwardly by the spring when the player disengages the clutch arms by striking the top of the device with the racket. To add interest to the game further appliances may be introduced, for example, wickets, miniature goals, baskets or suspended nets.
