Abstract: 1,143,740. Gas turbine engine combustion equipment. GENERAL ELECTRIC CO. Nov. 17, 1967 [Feb.24, 1967], No. 52465/67. Heading F1L. The invention relates to combustion equipment for a gas turbine engine and in particular to a method of inter-connecting sections of an annular flame tube by means of a corrugated spacer member so as to define annular cooling air passages between the flame tube sections. In the embodiment shown the combustion equipment comprises an annular flame tube disposed within an annular air-space formed by inner and outer walls 16, 15. The flame tube comprises outer sections 36 and inner sections 39, an end dome 41 and guide members 43, 44, the parts being spaced apart to form annular cooling air inlets 30, 31, 32, 33 as indicated in Fig.1. The cooling air inlet 30 is shown in detail in Figs.2, 3, 4, the flame tube section 36 and the dome 41 being spaced apart to form an annular passage 48 by means of a corrugated annular spacer member 53, the spacer member comprising circumferentially-extending portions 58, 59 and substantially radial portions 56. The guide member 43 is in close contact with the flame tube section 36. The parts are secured together by means of rivets 65 which are located at alternate radial portions 56, the rivets carrying spacers 67 which abut against the dome 41 and the tube section 36 so as to maintain the desired radial clearance 54. Openings 70 are formed in the flame tube section 36 downstream of the rivet connections 65 so as to allow flow of cooling air into the wakes of the connections. Smaller holes 71 are formed in the flame tube section 36 downstream of the radial portions 56 not associated with rivet connections. By locating the rivet connections at the alternate radial portions 56, the obstruction of the annular cooling air passage is minimized.

Abstract: 1,227,868. Cleaning moulding surfaces. GOODYEAR TIRE & RUBBER CO. 17 Sept., 1968 [17 Sept., 1968], No. 44048/68. Heading B5A. [Also in Divisions C3, C5 and C7] Surfaces of moulds for shaping articles of synthetic polymers are cleaned from deposits formed by contacting the surface in the presence of water and CO 2  with at least one substituted methylamine compound as hereinafter defined, by treating the surface with at least one of formic acid, acetic acid and propionic acid and drying the surface. The methylamine compound is defined as being characterized by forming a turbidity within 60 minutes when 11. per minute of CO 2  at 25‹ C. is passed through 1 1. of a solution of 10 to 20 parts of the methylamine compound per 100 parts by weight of methyl ethyl ketone, which solution has been aged for 8 hours at 25‹ C. and then warmed to 40‹ C. The process is particularly directed to cleaning moulds used for polyurethane and epoxy resin reaction mixtures. The mould may be made of a metal preferably coated with a release agent, or a cured millable gum silicone rubber, a cured natural rubber or synthetic rubber-like polymer, or a thermoplastic or thermoset polymeric material. Suitable release agents are polyethylene and polypropylene waxes and emulsions, natural and synthetic waxes, dimethyl silicone fluids, greases and higher polymers, soya bean fatty acids, vegetable lecithin and cephalin, soaps, fluorocarbons polyvinyl alcohol and fluorosilicones. The mould material may contain fillers such as pyrogenic silica, silica aerogels, organo-silane modified silicas, barium and cadmium titanates, zirconates and stannates, diatomaceous earth, clays, calcium carbonate, finely ground quartz, barites, iron oxide, zinc oxide, and titanium dioxide. The cleaning acids may be employed separately or together, or may be dissolved in an inert organic solvent. Particularly for cleaning silicone rubber moulds, they are preferably used successively in decreasing order of molecular weight. The cleaning process is said to restore the release properties of the mould and rejuvenate the surface definition.

Polyurethane elastomers are prepared by reacting an organic polyisocyanate with at least one glycidol to prepare a glycidyl carbamate, heating the glycidyl carbamate to form the corresponding 5 - hydroxytetrahydro - 1,3 - oxazine- 2-one and reacting this with an organic polyisocyanate so that the NCO to OH ratio based on the OH groups of the oxazine is from 0À9 to 1À2. The organic polyisocyanate is most suitably an NCO terminated prepolymer prepared by reacting a monomeric organic diisocyanate with a polymeric polyol, e.g. a polyether or polyester. Excess of the polyisocyanate may be reacted with the glycidol, which excess will then react with the oxazine formed by heating. Alternatively the glycidol may be reacted with a substantially equivalent of polyisocyanate and more polyisocyanate, which may be the same or different, may be added subsequently for reaction with the oxazine. The mixture of glycidyl carbamate and polyisocyanate is substantially stable and may be kept as such until heated to a temperature suitably in the range of 80‹ to 160‹ C. Conventional polyisocyanates and NCO terminated prepolymers are described. The rearrangement of the glycidyl carbamate to the hydroxy-tetrahydro-oxazine may be catalysed by catalysts, e.g. boron trifluoride adducts of monoethylamine, di-sec-butylamine, N,N-dimethylaniline and pyridine.
