Title: Improvements in carburettors
IPC: F02M23/09
Filed: 1931-01-27
Abstract: 372,287. Spray carburetters. ANDERSON, J. G., Gaywood House, Wood Street, Westminster. Jan. 27, 1931, No. 2680. [Class 7 (iii).] A substantially conical member 53, which may be grooved, is adapted to be actuated by suction to control the air intake. The carburetter casing has an outlet 2 provided with a throttle 61 and an inlet portion provided with inserted conical members 11, 13, which, in conjunction with a flanged member 7, form adjacent peripheral slots for fuel from an orifice 14, and extra air from an orifice 15 respectively. The member 53 is attached by a hollow rod 54 to a piston 56 of two diameters. Suction is transmitted to the smaller diameter through holes 59 and bore 58, and to the larger diameter through a pipe 77 connected to the engine side of the throttle. The lower face of the piston is open to atmosphere at 60. The function of the pipe 77 is, when the throttle is closed, to permit suction to act on the annular part of the piston 73 and lift the member 53, thus preventing an excessive feed of fuel. The fuel is supplied from an inlet 26 past a valve 23 urged towards its closed position by a spring 29. The valve is opened by suction transmitted through the duct 14a to a corrugated diaphragm 30, which may be depressed by a plunger 32a to flood, the carburetter e.g. at starting. The extra air is controlled by a ball valve 64 and screw 63. In a modification, Fig. 2, a conventional float-chamber 36 is employed, and the fuel is controlled by a valve 39 having a bore 41 leading to a chamber 42 to which air may be admitted by a ball valve 43 loaded by a spring 44 the compression in which may be adjusted by screwing the part 46. Extra air is admitted by an adjustable spring- loaded ball valve 69 to a recess 20, and the grooves on member 53 are of helicoidal form. In a further modification, Fig. 7, the fuel flows past a ball valve 48 the lift of which is limited by an adjustable member 49 through ducts 50, 51, in which air may be admitted. With an increase of fuel flow, the ball is raised and cuts off the air supply. In a still further modification, Fig. 10 (not shown), the member 53 and its actuating piston are arranged horizontally the piston and member being returned by a spring. The conical member may be acted upon directly by the suction.

Title: Heat exchange circuit
IPC: F25B49/02
Filed: 1968-01-19
Abstract: 1,218,063. Refrigerating; heating by circulation of fluids. AMERICAN AIR FILTER CO. Inc. 19 Jan., 1968 [24 Jan., 1967], No. 3046/68. Headings F4H and F4U. In a heat exchange circuit in which a fluid is circulated to be alternately vaporized and condensed, a condenser has at least two separate fluid flow paths which are controlled in accordance with either the pressure or the temperature of the fluid leaving the condenser. The condenser may have four flow paths leading to inlets 9a, 11a, 12a and 13a of a valve casing 10, as shown in Fig. 3. Fluid from the condenser flows through a casing outlet 14 to the remainder of the circuit. A piston 21 having sealing rings 22 slides in the casing between an upper position in which the inlets 9a, 11a and 12a are open and a lower position determined by a stop 20 in which those inlets are closed. The inlet 13a remains permanently open. The position taken up by the piston depends on the pressure in the chamber 27 below the piston acting against a compression spring 23. Thus if, for example, the pressure of fluid from the condenser rises, the piston will rise to open a further condenser flow path or paths and the resultant increased condenser cooling capacity will reduce the condenser outlet pressure. The chamber 28 above the piston has an outlet 16 with a relief valve 16a so that any fluid leaking past the piston from the chamber 27 maintains a constant pressure on the upper face of the piston. In a modification, Fig. 4 (not shown), the piston moves in accordance with the temperature in the chamber below the piston. That chamber includes a temperature responsive device of the type filled with expansible fluid which raises the piston with increasing temperature. The spring above the piston serves only to maintain the piston in contact with the device. The heat exchange circuit may be a compression-condensation refrigeration circuit, Fig. 1 (not shown), or may, as shown in Fig. 2, be a circuit including a heated vapour generator 41 and an air heating condenser 40. Vapour passing from the generator and the condenser drives an engine 42 which powers a fan 47 for passing air over the condenser, a pump 53 for moving fluid around the heat exchange circuit, a generator fuel pump 48, and a generator combustion air supply fan 44. The fuel supply is controlled by a valve 49 in accordance with the temperature of heated air leaving the condenser. An automatically controlled engine by-pass 45 maintains a constant pressure drop across the engine.
