Abstract: An aircraft waste storage system and method intended to avoid leakage of liquid waste from an aircraft waste holding tank through the tank outlet tube during flight. The system uses a valve movable from a position at a predetermined depth within the outlet tube to form a liquid-tight circumferential seal with the outlet tube interior surface during flight to an open position during ground servicing in which the valve is withdrawn into the tank to allow the waste to discharge. The waste system uses an electric motor and drive screw to move the valve, which is controlled from the aircraft. It incorporates an alarm to provide a warning if the valve has failed to reach the predetermined depth within the outlet relied upon to prevent leakage.

Abstract: A fluid flow control valve of the ball type has a unitary body moulded in an elastomer and defining inlet and outlet passageways and a spherical cavity accommodating a plastic, ball-shaped closure member. The closure member is located in the cavity by forcing it, together with its actuating spindle, through a bore formed in the body until it is sealingly located, as a snap fit, in the cavity, during which process the bore is resiliently deformed outwardly but subsequently resiles into contact with the actuating spindle. The valve may, thus, simply have a pair of injection mouldings and, relative to prior ball valve constructions, is therefore simpler and more economic to manufacture. The body is integrally formed with a peripheral external recess whereby it may readily be sealingly engaged, simply as a snap fit, in, for example, an aperture formed in the base or a compressed sir filter bowl, the valve acting as a manual drain valve.

Abstract: An actuator system for controllably rotating a rotary (valve) element positioned in a pressurized fluid vessel. A double-acting piston-cylinder intermittently rotates a ratchet wheel operatively connected to the rotary element. The cylinder is sealed within a bellows chamber assembly in the vessel and is controllable by a pressure source positioned outside of the vessel. The wheel is rotated by a ratchet member biased against the ratchet wheel and attached to the cylinder and reciprocable therewith. A ratchet pawl biased against the ratchet wheel prevents the reverse rotation of the wheel, and thereby of the rotary element.

Abstract: An internal valve and metered positive displacement pump for a pressure fluid tank. The tank defines a fluid compartment, and first and second vessels are positioned within the protective envelope of the tank. A bellows pump assembly disposed in the first vessel includes a bellows and a piston cylinder arrangement positioned within and attached to the bellows. Pressurized fluid is pumped into and out of the first vessel to actuate the piston cylinder arrangement. With this actuating movement fluid is pumped from the compartment through a valve in the second vessel and into the second vessel for removal therefrom. The valve is normally closed against the working pressure of the fluid in the compartment by a spring bellows relief assembly in the second vessel. The force of the fluid pump by the piston cylinder arrangement opens the valve, and a check valve prevents fluid from flowing back from the valve into the first vessel.

Abstract: A valve is in the form of a valve body having a valve inlet, a valve outlet and a valve seat disposed between the inlet and the outlet. A valve closure member is movable between a first, closed position in abutment with the valve seat and a second, open position in which it is displaced from the valve seat.A shaft is pivotally mounted within the valve body and one end is connected to an actuating handle, by means of which it is pivotable. An arm is connected to the shaft and to the valve closure member, whereby movement of the actuating handle causes opening and closing of the valve.The positioning of the pivoting portions of the valve and the spring within the valve body (i.e. in an aperture actually within the material forming the valve body) means that the only item other than the valve closure member in the path of the material being discharged is the arm, and that when in the open position the valve closure member causes no constriction of the bore.

Abstract: Safety device for liquefied gas bottle valves for use with a quick-coupling connector. The device is positively controlled and activated by the same control knob as the valve. The quick-coupling connector can be disconnected only when the valve is completely closed, and vice versa the valve can be opened only when the quick-coupling connector is inserted perfectly, all of which can be effected by a single fixed-amplitude rotation of nearly 360.degree. of the knob. This rotation causes synchronously both the activation of the internal dispensing valve member and the locking of the quick-coupling connector.

Abstract: The valve includes a rubber gasket which is clamped and sealed to the sheet metal vessel of a fuel/water separator by a rivet nut and which serves as a seat for the valve head of a valve member that is screwed into the rivet nut. When the valve member is opened, the valve head moves upwardly away from the gasket to allow air to enter the vessel through one passage in the valve member and to enable liquid to drain from the vessel through a separate passage in the valve member. The valve member may be formed as two die cast parts which interfit with one another to define the passages and which eliminate the need of machining the passages. Alternatively, the valve member may be a single die cast part with internal passages, there being a die cast operating knob attached to the valve member.

Abstract: A pressurized flushing apparatus for commodes in which low volumes of pressurized water are used for flushing. The apparatus includes a pressurizeable tank having a closed water outlet. The tank is pressurized by the introduction of pressurized water into the tank until a pressure of between 8 and 25 psi is achieved. Within the tank is a bellows to which a plug is attached to one end for closing the water outlet. A restrictable open channel connects a pressure zone above the water in the tank with an internal chamber located within the bellows. The open channel is consticted by a needle valve which controls the rate at which the pressure within the pressure zone and the internal chamber are equalized. When the pressure within the internal chamber is reduced to ambient pressure, the bellows will collapse and withdraw the plug from the water outlet. When this occurs, the pressurized water within the tank will be forced out of the tank and into the toilet bowl.
