Abstract: A carbonated beverage appliance in accordance with the present invention includes a housing and a carbonating head assembly configured to releasably engage a top end of a bottle containing a liquid to be carbonated. The bottle is engaged with the head assembly in a manner so as to provide a liquid and gas-tight seal. A tube is arranged in the housing for directing a flow of pressurized gas from a gas cylinder to the liquid within the bottle to produce a carbonated beverage. The carbonated beverage appliance includes a quick-connect mechanism for attaching a gas cylinder to the appliance, and a dispensing mechanism for the on-demand dispensing of a carbonated beverage from the bottle while it is attached to the appliance.

Abstract: The present invention relates to an apparatus and method for an air bypass system for a natural draft cooling tower that employs a wet heat exchanger, a direct dry heat exchanger or an indirect dry heat exchanger to extract heat from a heated fluid, which is usually liquid or steam.

Abstract: A carburettor includes a primary air passage (19), an adjustable throttle valve (8) situated within the primary air passage, a fuel supply nozzle (28) communicating with the primary air passage and connected to a fuel metering valve for varying the amount of fuel discharged through the nozzle. The fuel metering valve includes an elongate sleeve (32) movably accommodating an elongate valve member (33). The sleeve and valve member define a fuel inlet space (35). A fuel inlet (37) communicates with the fuel inlet space. A fuel outlet (39) passes through the wall of the sleeve (32) and communicates with the fuel supply nozzle (28). A portion of the outer surface of the valve member (33) is so profiled that the valve member (33) is movable relative to the sleeve (32) such that the area of communication between the fuel inlet space (35) and the outlet (39) varies progressively between a maximum and a minimum value.

Abstract: To enable a carburetor having a manual choke valve to be provided with a gas mixture of adequate concentration in accordance with the atmospheric temperature when an engine starts up and when the engine runs continuously right after starting up, there is provided an open-close valve 40 that slides reciprocatingly inside a valve hole 4 provided partway along a bypass air passage 5 for bypassing a choke valve 3 so that the bypass air passage 5 is opened and closed. The open-close valve is pressed by urging means and slides in accordance with an angle of rotation of a choke valve shaft 30 while a distal end side is in continuous contact with a side face of the choke valve shaft 30; a projecting part 42 that projects from and recedes into a distal end of a body 41 is urged by a coil spring 42b so that a distal end face is pressed to the side face of the choke valve shaft 30. The urging means comprises a temperature-sensitive material that expands in the direction of sliding at a prescribed temperature or higher.

Abstract: An object of this invention is to provide a liquid material vaporization apparatus that is capable of increasing the flow rate of a carrier gas without changing the shape of a nozzle. The liquid material vaporization apparatus comprises a gas-liquid mixing chamber in which a liquid material and the carrier gas are mixed, a liquid material introduction path that introduces the liquid material into the gas-liquid mixing chamber, a carrier gas introduction path that introduces the carrier gas into the gas-liquid mixing chamber, a vaporization nozzle section that is communicated with the gas-liquid mixing chamber to subject a mixture of the liquid material and the carrier gas to flash boiling, and a mixed gas derivation path that is communicated with the vaporization nozzle section to derive the mixed gas vaporized by the vaporization nozzle section.

Abstract: A carburetor for feeding separate lean and rich channels of an engine intake duct includes a body having a mixing passage with an air intake side and an engine outlet side. A throttle shutter is rotatable about an axis transverse the mixing passage, and a partition is located within the mixing passage upstream of the throttle shutter. The downstream edge of the partition is adjacent the throttle shutter axis whereby in use of the carburetor the partition defines an extension of the lean and rich channels upstream of the throttle shutter, the partition thus providing substantial isolation between the lean and rich channels for all rotational positions of the throttle shutter. In a preferred embodiment a choke shutter is located upstream of the throttle shutter and is rotatable about a further axis transverse the mixing passage, the upstream edge of the partition being adjacent to the axis of the choke shutter.

Abstract: A versatile rotary carburetor has an idle adjustment needle, a high speed adjustment needle, and preferably an air bypass screw which are substantially parallel to one another and are axially exposed for adjustment in a substantially common direction. Preferably a cammed rotary throttle valve is seated in a body of the carburetor for rotation about and axial movement along an axis. The rotary throttle valve intersects a mixing passage in the body, and carries a through-bore that variably generally aligns to the mixing passage upon rotation of the throttle valve. The throttle valve projects axially through an external surface of the body and threadably receives the idle adjustment needle oriented concentrically to the axis.

Abstract: A carburetor assembly includes a base plate (12) having an air bypass passage (30) extending there through, with air channels (71-74) formed in the surface of the base plate intersecting the air bypass passage and each of the butterfly bores (25-28) of the base plate. An adjustable air bypass valve (31) is mounted on the base plate and controls the movement of air through the bypass passage. A valve needle (50) is adjustably mounted to the valve body (48) for adjustably constricting the flow of fluid through the radially extending air inlet ports (60) and through the base plate air bypass passage, to allow for the adjustment of the volume of the air delivered to the engine at idle speed, independently of the movements of the butterfly valves.

Abstract: The fuel preparation system of an internal combustion engine is provided with an air bypass line which delivers fresh air directly to the intake manifold downstream of the mixture generator, which may be a carburetor, for example. The air flow through the bypass is controlled, firstly, by a valve actuated in synchronism with an air flow meter in the main induction tube and, secondly, by a pressure controlled valve. The pressure controlled valve is connected to sources of different pressure by solenoid valves which are operated on the basis of engine information, for example the exhaust gas composition.

Abstract: A process and related apparatus for regulating the fuel-air mixture delivered to the combustion chambers of an internal combustion engine by the admission of auxiliary air the quantity of which corresponds with the quantity of the aspirated fresh air forms the subject of this invention. An air bypass line is provided for bypassing a venturi constriction disposed in a suction tube upstream of a throttle flap valve. Associated with the air bypass line are a pressure regulating valve, a bypass throttle device and a control circuit including a pair of shut-off valves, or alternatively a three way valve, with an appropriate control for controlling the valves and accordingly the reduced pressure produced by the venturi constriction, which is communicated to the bypass throttle device, or the control pressure of the pressure regulating valve.
