[Also in Group XIII] In a de-icing apparatus for aircraft elements air from the vicinity of the leading edge of the element is fed to a combustion chamber independent of the aircraft propulsion plant, the products of combustion being conveyed to the outer surface of the element, over which they are discharged as a thin layer which mingles with the boundary layer and thus improves the aerodynamic qualities of the element. As applied to an aerofoil such as a wing 1, Figs. 1 and 2, air entering an opening 3 in the undersurface near the leading edge passes into a combustion chamber 5, in which fuel supplied to a burner 6 is ignited by a sparking plug 8, the products of combustion passing through pipes 10 to slots 11 in the upper surface. through which they are discharged in a rearward tangential direction. Fig. 4 shows a half-section of an engine air intake, in which combustion air enters through an axial duct 12 and cooling air through a co-axial annular duct 13. A portionof the cooling air passes through passages 4 to the independent combustion chamber 5, the combustion products being led to an annular duct 11 near the leading edge of the inner surface 17 of the cooling air duct. from which duct they pass through slots 22 rearwardly over the surfaco 17. In the ease of the air inlet shown in Fig. 7, the products of combustion are fed to two duets 11a, 11b from which they are discharged rearwardly over the inner and outer surfaces 17, 18 of the cooling air duct and also, through ducts 30. to the leading edge of the intake. A duct 28a within the duct 30 is traversed by cold air entering a chamber 28 surrounding the duct 11a. In the further embodiment shown in Fig. 13, an inner cowl 1a carries an axial burner 5 to which air is supplied through openings 34, and the combustion products pass through pipes 10 and openings 35 over the cooling air duct surface 17. The pipes 10 lie in depressions 3S at the leading edge of the air intake 12, cold air passing through passages 37 formed by the depressions 38 and then being discharged over the surface 17 through openings 39. In addition, hot lubricating oil may be circulated by pipes 42, 43 through a, chamber 40 at the leading edge 15 of the outer cowling.

Title: Improvements in or relating to Carburettors for Explosion Motors.
Inventor: CHANARD AUGUSTE
IPC: F02M7/133
Filed: 1918-12-17
Abstract: 121,735. Chanard, A. Jan. 6, 1917, [Convention date]. Spray carburettors. - A spray carburettor is provided with a main nozzle c and supplementary nozzle h in the choke tube f, and with a by-pass nozzle j in a chamber k which delivers mixture through an orifice k' near the edge of the throttle i in its closed position. The outlets of the nozzles h, j are at the level B-B which the fuel attains in the float-chamber a when the float-valve closes the inlet passage b. This occurs when the engine is stopped or running slowly. The level A-A is that which the fuel assumes in the float chamber when the engine is running at normal speeds, and when the inlet of fuel through the passage b is equal to that discharged through the nozzle. At intermediate speeds, the fuel assumes a level between A-A and B-B. The rise of the level during stoppage or slow running provides a reserve of fuel which facilitates starting and accelerating. The nozzles h, j are fed through a passage g at the level A-A, or the nozzle j may be fed through a separate passage at the same level. To prevent an excessive flow of fuel through the main nozzle, and also a gravity flow therefrom before it comes into action when the level is above A-A, a braking effect on the fuel flow is produced by directing the nozzle downwardly, as shown in Fig. 1, the highest portion of the bend reaching the level B-B. The braking effect may also be obtained, as shown in Fig. 2, by enlarging the upper part of the nozzle and providing capillary passages l therein or, as in further modifications, by placing wicks or capillary tubes in the enlarged part or forming such part to produce opposed or annular sheet-like capillary passages.

[Also in Division D1] A clear product is obtained by heating together i.p.o. a C 1-4  saturated monohydric alcohol a methylol compound of an aminoplast-forming nitrogen compound with 0À5-10 moles of a dicarboxylic anhydride and 0À75-10 moles of an aliphatic C 8 -plus monohydric alcohol per mole of methylol compound. The methylol compound may be derived from melamine, urea, ethyleneurea, propyleneurea, hydroxypropyleneurea or acetyleneurea and may be partially etherified with a C 1-4  alkanol. Suitable anhydrides are those of C 4-10  aliphatic dicarboxylic acids, phthalic acid or naphthalic acid. The C 8 -plus alcohol is preferably saturated, having 16, 17 or 18 C atoms. An optional component is 0À2-0À6 moles per mole of methylol compound of a C 16 - plus aliphatic monocarboxylic acid. The reaction may be conducted by heating the reactants in 10 times their weight of the solvent alcohol until the mixture becomes clear, then distilling off the alcohol and heating the mixture at 160-180‹ C. The products may be dissolved in a hydrocarbon or chlorinated hydrocarbon to give a solution suitable for the " dry " impregnation of a textile material. This solution may also contain a water repellant material, e.g. a wax in amount 50-150 wt. per cent of the product, and 5-15 g.p.1. of an alcoholate of Al, Zr or, Ti with a saturated C 1-4  alkanol. In examples methylol derivatives, which may be partly methylated or ethylated, of melamine or urea or ethyleneurea are heated in methanol, or isopropanol with phthalic or maleic or succinic anhydride and dodecanol or hexadecanol or octadecanol and optionally with stearic, palmitic or cerotic acid to give products which are further heated, and on cooling prove to be soluble in perchlorethylene, trichlorethylene, and in hydrocarbons and chlorinated hydrocarbons in general.
