Title: Improvements in or relating to carburetting apparatus, particularly for internal combustion engines of motor vehicles, air craft, and the like
IPC: F02M7/18
Filed: 1930-08-11
Abstract: 362,924. Spray carburetters. HALSEY, W., 4, Densome Wood, Wood Green, Salisbury, Wiltshire. Aug. 11, 1930, Nos. 24011/30 and 11311/31. Class 7 (iii).] The fuel flow is controlled by a valve actuated by a diaphragm, or the equivalent, subjected to the vacuum on the engine side of the throttle valve as modified by an inflow of air from a source at which the density is substantially the same as that of the main supply to the carburetter, the control being such that a constant fuel to air ratio is maintained under all phases of speed and air density, but the flow is restricted if the engine speed becomes high relatively to the throttle opening. A casing 10 is divided by a flexible corrugated diaphragm 11 into two compartments 12, 16, of which 16 is in communication through ducts 28, 29, Fig. 2, with the engine side of the carburetter throttle valve, and 12 is in communication through ducts 13, 13a with an annular chamber 14 supplied with fuel from an overhead tank through a filter 15. The diaphragm carries at its centre a screw 17 which is adapted to actuate in one direction, a fuel valve 20 with two seatings 22, 23, and, in the other direction, a supplementary air valve 21. When the engine is at rest, the valve is closed against the seat 22 and the fuel is cut off. During running, the valve is held in a position between the seats, but should the vacuum become excessive, it is drawn downwardly towards the seat 23 and the flow of fuel is reduced ; at the same time the valve 21 is opened and air admitted to the chamber 16 and thence to the induction pipe. To regulate the rate at which the chamber 16 is exhausted, a needle valve 25 is provided which controls an orifice 27 between the ducts 28, 29, the valve being loaded by a spring 36 and sliding in a bush 32, its outer end 31 being actuated by a setscrew 39 mounted in a lever 38 connected to the throttle-actuating mechanism. Initial adjustment is effected by rotating the bush 32. Any sudden opening of the throttle valve releases the diaphragm abruptly and fuel is forced to the float chamber to facilitate acceleration. A decrease of air density will result in a lowering of the diaphragm and reduction of fuel supply. A valve 40 loaded by a spring 41 is adapted to control a further supplementary air supply and is connected, through a lever 42, with adjustable fulcrum, to the valve 21. Fuel may be bye-passed direct to the float chamber through a duct 48. In a modification, a simpler form is described in which the fuel valve is located in the fuel-pipe line. In a further modification, the diaphragm is embodied in the carburetter float chamber, and a piston on the fuel valve stem acts as a pump to facilitate acceleration. Water vapour may be admitted through the supplementary air valve, a porcelain diffuser 67, Fig. 9, receiving water from the radiator through a perforated tube 68, air entering through holes 69 and passing to the air valve by a pipe 70 of small bore.

Title: Axial flow fan assembly
IPC: F04D19/00
Filed: 1972-05-22
Abstract: 1370573 Axial-flow fans HUDSON PRODUCTS CORP 22 May 1972 [20 Dec 1971] 24026/72 Heading F1C An axial flow fan comprises first and second impellers 19, 20 of equal outer diameter and rotating at a desired speed within a ring 18 of constant inner diameter, the blades of the second impeller being of greater average pitch than those of the first impeller, and the axial spacing  between the impellers being considerably less than would be necessary for the impellers to do the same useful work with the blades of the second impeller at the same average pitch as the blades of the first impeller and rotating at the desired speed. For 14 foot diameter impellers, the centres of the hubs may be spaced apart by 20 inches, whereby the air entering the second impeller retains most of the whirl velocity with which it left the first impeller, this necessitating the greater blade pitch provided on the second impeller. The blades of the second impeller are offset circumferentially relative to those of the first impeller to avoid the most turbulent part of the air stream. As shown, the fan may be used to draw air through a heat exchanger 11.

Title: Improvements in or relating to a method of fuel oil injection for direct injection oil engines or motors and apparatus therefor
IPC: F02M61/04
Filed: 1936-09-04
Abstract: 484,699. Liquid-fuel injectors. RIEGELS, O. L. A. Sept. 4, 1936, No. 24228. [Class 7 (iii)] To obtain a steady discharge of fuel from an injector, a stop valve, which is normally open, is closed as the injection valve is opened and the shapes and areas of the openings controlled by the valves are proportioned in relation to the forms and lifts of the valves to provide for the passage of equal volumes of fuel during the same time intervals. Closing the stop valve sets up pressure waves, in the fuel system, equal in intensity and opposite in phase to the rarefaction waves caused by the opening of the injection valve. A pump or equivalent supplies fuel from a tank through a duct 4 in a valve housing 1 to a chamber 2x around the tip of an injection valve 3. When the valve is closed the fuel is conveyed through a passage 5 past a stop valve 8 back to the fuel tank. When the increase in fuel pressure opens the valve 3 a rocking lever 11 forces the stop valve 8 on to a replaceable seat 8a. To enable the lift of the valves to be adjusted, the lever 11 is mounted on an adjustable eccentric 11a and the heads of the valve stems are provided with screwed caps 10. The valve 3 may be a pintle valve and the valves 3, 8 may be operated mechanically as described in Specification 391,958.

Title: Improvements relating to milking machines
IPC: A01J5/10
Filed: 1927-09-14
Abstract: 277,672. Aktiebolaget Separator. Sept. 17, 1926, [Convention date]. Cow-milkers.-In milking-machines of the kind wherein the pulsations in the teat cups are regulated by a primary pulsator which is connected with a secondary pulsator in proximity to the cups by a line wherein vacuum is interrupted at regular intervals by short puffs of air, in order that the primary pulsator may be arranged near the point of milking a direct mechanical drive therefor from the vacuum pump is dispensed with. In the pulsator shown, a piston B with ports H moves in a cylindrical portion A having ports C, E open respectively to the atmosphere and to the inside of the pulsator, which is in constant communication at F with the vacuum line of the plant, the connection G leading to the secondary pulsator. While the ports H open to the atmosphere, air pressure will raise the piston and cause it to press upward a looselyguided rod J connected to a crank K on a spring- controlled balance mass or flywheel P or a, wheel N geared thereto. On the return swing of the mass under the action of the tensioned spring the rod J engages the piston and returns it to its lowest position. Instead of being unconnected to the piston the rod J may be secured thereto and connected to the crank by an openfork shaped part. A weight upon the crank and a spring may be provided to ensure that the piston shall fall to its lowest position when the apparatus is no longer being used, or the piston or the cylindrical part may be magnetized for this purpose. Fins or wings S tend to damp the oscillation of the flywheel. By closing the cylindrical part at the top the vacuum line may be coupled directly to the upper portion thereof and the pulsator housing need not then be under vacuum. Also, the rod J may be omitted and the crank arranged to bear directly on the piston as by a roller on a ball bearing. Instead of having a linear motion the piston may oscillate about a centre within a part-circular casing. A spring-pressed rod, passing through a hole in the housing and adapted to be pressed inwards to engage a nose on the crank, may be provided for starting the pulsator.
