Title: Wrinkle finish coating composition containing a vinyl chlorideí¬vinyl acetateí¬vinylalcohol terpolymer and an alkyd resin
IPC: D06M15/39
Filed: 1953-11-17
Abstract: A wrinkle drying coating composition comprises an organic solvent, a terpolymer of vinyl chloride, vinyl acetate and vinyl alcohol with either (a) an alkyd obtained by cooking together, by weight, 19.0 per cent glycerine, 38.0 per cent phthalic anhydride, 21.5 per cent linseed oil acids and 21.5 per cent tung oil, or (b) an alkyd obtained by cooking together 12.28 per cent glycerine, 19.93 per cent phthalic anhydride, 1.15 per cent maleic anhydride, 16.94 per cent linseed oil acids, 23.12 per cent rosin and 26.58 per cent tung oil. In a modification the tung oil is replaced by dehydrated castor oil or oiticica oil.  The terpolymer specified consists of 91 per cent vinyl chloride, 3 per cent vinyl acetate and 6 per cent vinyl alcohol.  The composition is preferably made by mixing the chosen alkyd with a solvent therefor, e.g. toluol, mixing the resulting solution with a pigment to form a paste and mixing the paste with a solution of the alkyd and a metal drier, e.g. cobalt naphthenate together with a solution of the terpolymer in the same solvent or a solvent compatible with the alkyd resin solution and thinning the composition to a sprayable consistency with further solvent. Examples are given in which the solvents and pigments specified respectively toluol, xylol, cyclohexanone and methyl ethyl ketone, and ultramarine blue, titania and magnesium silicate.  Specification 599,277 is referred to.

A steam or hot-water boiler comprises a horizontal tubular shell, a tubular furnace chamber and flue extending longitudinally through the shell from the front end to a combustion chamber at the rear, first and second pass tubes respectively conveying the combustion gases through the water space within the shell forwardly to the front and backwardly to the rear of the boiler, heat insulating lagging surrounding the shell, an outer casing spaced from the lagging, and a fan delivering air from the space between the outer casing and the lagging to the furnace chamber, an opening at the rear allowing the admission of air to said space. Within a longitudinal boiler shell 10 surrounded by rockwool lagging 23 are a furnace chamber 12, a furnace flue 13 and a combustion chamber 15. Combustion gases from the latter successively traverse first pass tubes 16 arranged in arcuate formation around the furnace chamber, a transfer box 18 at the front end of the boiler, and second pass tubes 20 of smaller crosssection than the first, before leaving by an outlet 22. Above the tubes is the normal water level 14. An outer sheet steel shell 24 is spaced from the lagging and provides a mounting for subsidiary equipment. The fuel injection apparatus 26 with a rotary cup type of burner is mounted on the front end of the casing. Air enters the space between the lagging and casing by louvres 36 and is heated by any heat escaping through the lagging before being forced by a fan 30 driven by an electric motor 31 into the furnace chamber 12. In the rear wall two doors give access to the smoke box 21 and the ends of the second pass tubes whilst a third door gives access to the combustion chamber and the adjacent ends of the first pass tubes.

The inert atmosphere may be e.g. neon or nitrogen or a reduced pressure of 10-4 to 10-6 mm. Hg.  A one-stage heating process may be carried out within the range 2500-3000 DEG C. at atmospheric pressure or 2000-2500 DEG C at the above reduced pressure.  Alternatively the mixture may be heated at a minimum of 1450 DEG C. to melt the mixture and form the metal carbide followed by heating at a higher temperature, up to 200 DEG C. below the boiling point of the film, e.g. about 3700 DEG C. to evaporate the silicon.ALSO:A film of a carbide of at least one of Ta, Nb, W, Hf, Mo and V is formed on the internal surface of a carbon container by heating the container having therein a mixture of the metal, sufficient to form a film at least 0.1 mil thick, and silicon in amount at least one quarter the weight of metal, in an inert atmosphere at a temperature sufficient to melt the mixture and react the metal with the carbon surface and to volatilize the silicon, but below the boiling point of the carbide film.

Abstract: 576,417. Endless tracks for vehicles. WINGFOOT CORPORATION. March 11, 1943, No. 4018. Convention date, July 15, 1942. [Class 79 (i)] An endless track for tanks and vehicles comprises a plurality of parallel, laterally. spaced belts 20 and a plurality of transverse metal shoes 22, 24 secured to the cables, each belt being formed by a single rubber-covered wire or cable 26 wound helical-fashion so that each turn extends lengthwise of the belt. In the construction shown in Figs. 1, 2, 3 and 5, four belts 20 are each enclosed in a rubber cover 28 ; an outer rubberized fabric cover 30 may also be provided. The cables 26 are preferably brass-coated and the rubber 28 is vulcanized thereto. The ends of the cables are clipped or otherwise secured to adjacent cables to hold them in place. Two or more belts 20 may be used to form a track ; as shown, four are used, and they are connected together by main shoes 22 extending right across the track and subsidiary or link shoes 24 leaving a gap 69 for engagement with the teeth of a driving sprocket 58. Each shoe 22 is made in two parts 34, 36 secured together by rivets 38 so as to clamp the belts 20 in recesses 39 formed in the parts. Pins 42 embedded in recesses at each end of the shoe parts serve to align the parts and are prevented from end movement by adjacent rivets 38 which engage grooves in the pins. The shoes 24 are similarly made in two parts 62, 64 riveted together at 66. The recesses formed in the shoes for the reception of the belts 20 are flared as shown at 56, 67 to facilitate the bending of the track around the supporting and driving wheels. The abutting ends of the shoes are curved also to facilitate the bending of the track. Central guide members 46 are secured to the main shoes 22 by rivets 48. In a modification, Figs. 6 and 7 (not shown), rubber collars or washers 70 surround the belts 20 between the ends of the shoes 22, 24 and seal the recesses 39, 65 in which the belts are clamped. In another modification, Figs. 10 and 11, the belts 20 are replaced by single cables 80 or 82, each cable passing several times round the whole length of the track and having its ends secured at 130 to one of the shoes. Each cable is rubbercovered and passes through cylindrical grooves formed in the shoes 84, 86 when the two parts thereof are riveted together. The grooves in the shoes near the ends of the cables are inclined as shown in Fig. 10, but in the remainder of the shoes they are parallel to the length of the track. The main shoes 84 are formed with recesses 120 co-operating with semi-cylindrical parts on the link shoes 86 to form a hinge joint to prevent grit from working into the track.
