Abstract: 315,224. Sturm, W. July 9, 1928, [Convention date]. Addition to 287,902. Spray carburettors.-The parent Specification describes a carburettor having an air throttle b, and in which a main choke tube c is connected by a duct h with the air space of a float chamber e, and surrounds an auxiliary choke tube d into which the fuel nozzle k discharges. The fuel passage has a branch m the mouth n of which opens into an auxiliary air passage 1 located at the side of the main choke tube c, and controlled by an automatic valve 2. According to the invention, the valve 2 is adapted to actuate means for controlling the fuel flow through the nozzle. The valve may actuate, through a gear wheel 4 and teeth, a coned valve 5 which, as the valve 2 opens, closes the mouth n, reduces the air flow through branch m, and increases the fuel supply. In a modification, the valve 5 is placed transversely of chamber 1, and is moved bv a forked extension of valve 2. In a further modification, Fig. 3, an extension 7 of valve 2 moves over the mouth n. In a further modification, the branch m is dispensed with, and the valve 2 actuates a needle valve in the nozzle k. In a still further modification, the branch m is again dispensed with, and the valve 2 actuates a shutter over the inlet end of choke tube d into which the nozzle k delivers at rightangles.

Class 98 (2). A material which on exposure and heating without application of liquid or vapour produces a positive copy of an original comprises a black base web bearing a transparent coating containing ferric ammonium citrate, ferric ammonium oxalate, or a mixture thereof, the exposed and developed areas appearing white. To augment the vesicular image produced, an undercoating containing a toning agent such as potassium ferrocyanide, potassium ferricyanide, silver nitrate, gallic acid or aniline may be applied to the base before the light-sensitive ferric salt layer to provide a white or coloured compound where exposed. The ferric salt and toner layers preferably include a colloid such as gelatin or polyvinyl alcohol. To avoid oxidation of the image as in the case when potassium ferrocyanide is used in the toner layer, an airtight outer coating may be applied or a reducing agent such as an aldehyde, ketone, carboxylic acid, hydroxycarboxylic acid (e.g. glycolic acid), an aliphatic polyhydroxy or amino compound, an amino acid, or a sugar (e.g. glucose) may be included in the ferric salt layer.

[Also in Groups XXVI and XXIX] A member movable in response to the difference between the pressures in the duct upstream and the duct downstream of an adjustable throttling device controls the amount of fuel fed to a gas generator. In Fig. 1 a free piston gas generator A supplies a gas turbine B by way of a reservoir 18 and a pipe 19. A throttling valve 20 is provided and is controlled by a speed governor 21. The supply of fuel is controlled by a piston 26 under the control of a valve 25 which is operated by a piston 22 the opposite sides of which are connected to opposite sides of the throttling valve. A discharge valve 46 opens when the pressure drop across the throttling valve exceeds a predetermined amount. A buffer tank 51 retards the opening of the valve 46 on sudden closing of the throttling valve, the non-return valve 50 closing in this case. If a cylinder 48 and pipe 49 are big enough they may themselves comprise the buffer tank. In Fig. 2 the gas generators A supply a common reservoir 18a which supplies several gas turbines B. Lifting of either the valve 25 or the valve 25a can permit supply of pressure fluid to the cylinder 27 but both valves must be lowered to release fluid from the cylinder. The fuel control incorporates resilient links constituting circuit breaking devices such as springs 30, 30a. In Fig. 3 the fuel supply is controlled by a piston 26 associated with a control valve 25. A calibrated orifice 45 is located in a pipe 24a leading to branch pipes connected through non-return valves to the downstream sides of the throttle valves 20, 20a. The gas generators may be of opposed piston type. There may be several gas generators and several turbines and the number of generators may be different from the number of turbines. The machines for delivering compressed gas may be free-piston air compressors. There may be a direct connection between the fuel supply and the throttle valve. The throttling passage is reduced on an increase of speed. The pressure drop due to throttling remains practically constant.
