Abstract: A valve used in a sewage handling system allows outer casing components to be disconnected from each other while both of the fluid transporting or retaining components that are connected to the valve remain sealed from the environment when the valve is in a closed position. Yet, the valve can be operated by simple rotation of a single actuator. For example, the valve connects a conduit connected to a toilet with a sewage holding tank. The valve includes first and second connecting parts of an outer casing which are circular cross section housed cylinders with one end perpendicular to the axis of elongation of the cylinder and the second end forming an oval face disposed at an angle of about 35.degree.-55.degree. to the axis of elongation.

Abstract: The emptying of the contents of a holding tank for a recreational vehicle or the like into a land based water closet is greatly simplified, and made much less unpleasant. A portable tank has wheels at one end and a handle at the other, with a discharge valve located adjacent the handle. A deployable stationary support is provided with the tank. The deployable support includes collars engaging stub shafts extending outwardly from the sides of the tank, and two sets of legs which provide a supporting base. As the tank is moved into a vertical position it moves to a point where it is no longer supported by the wheels, but instead is supported by the legs, and the connection between the tank and the legs is automatically unlatched. The tank is then tilted (pivoted) about a horizontal axis so that the discharge valve is right above a water closet. A tube extends from the valve into the toilet to about the point of the liquid level.

Abstract: A closed pressurized container for producing a carbonated beverage of superior quality by providing for contact therein of water and a solid carbonation source. The pressurized container is designed to withstand the pressures and temperatures generated during the preparation of a carbonated beverage from a solid carbonation source. In a preferred embodiment, the container is a rigid receptacle in the shape of a wide mouth bottle adapted to receive a large cap or cover. A perforated basket is mounted inside the cover, and is accessible to water in the bottle when that vessel is turned upside down to an inverted position. A spring loaded, manually operated valve is provided in the cover to permit venting of carbon dioxide from the interior thereof after the water-based mixture within the container has become sufficiently carbonated by absorbing carbon dioxide released by contact of water with the solid carbonation source.

Abstract: A spreader for distributing particulate material, particularly adapted for use as both a package for particulates and as a disposable spreader, comprises a dispenser, a pair of wheels mounted at opposite ends of the dispenser and a handle for advancing the spreader along a given path as the dispenser rotates. The dispenser has inner and outer chambers, the inner chamber adapted to act as a reservoir for particulate material, the outer chamber adapted to provide a circumferential passageway for particulate material passing from the inner chamber to the exterior of the spreader. A one-way valve arrangement in the passageway restricts particulate flow to the exterior when the dispenser is rotated in one direction but permits flow when rotated in the opposite direction.

Abstract: A manually actuatable fluid dispenser comprises a plastic bottle container which includes an upstanding bottle neck portion having a flexible bellows formed integrally on one side thereof operable by a reciprocal trigger member which engages the bellows through a trigger spring for exerting a sustained but limited force on the bellows, and reaction force on the trigger member, over extensive trigger actuation travel and speed. The upper end of the cylindrical neck of the container is closed by a dispenser body which includes a fluid passage having a check valve disposed therein for controlling the flow of fluid in the fluid passage. A fluid tube disposed in the bottle neck includes a seal for fluid isolation of the bottle neck from the bottle, and a check valve for allowing flow of fluid from the bottle into the bottle neck.

Abstract: A manually charged fluid dispenser includes a charging cylinder disposed in the mouth of a bottle and a manually reciprocable piston carried on a charging rod which extends out each end of the cylinder. The charging rod has a differential diameter for providing hydraulic return thereof by fluid pressure in the charging tube after manual charging of the tube. The charging tube is in fluid communication with a spray nozzle mounted on the bottle and tube through a ball valve which is selectively unseatable by a cam actuated by a slidable trigger, which is hydraulically biased by a piston which is in connection with pressurized fluid at the ball valve. An alternative embodiment of the charging cylinder provides a charging rod slidable in a draw tube disposed above an end of a charging cylinder and a piston slidable therein so that fluid pressure in the cylinder will return the rod to its rest position.

Abstract: A child's motorized swing includes a frame from which a seat is suspended by spaced-apart hangers pivotally connected to the frame so that the seat and its occupant can swing like a pendulum. A battery operated drive unit mounted on the frame adjacent one of the hangers rotates a small crank situated adjacent the hanger. A resilient, lost motion linkage connected between the hanger and the rotating crank applies reinforcing impulses to the hanger which maintain the weighted seat in oscillation at its natural frequency.

Abstract: A viscous fluid clutch including a clutch plate member rotatably mounted in the clutch housing, and serving as a rotatable wall dividing the chamber within the housing into an annular working chamber adjacent one face thereof and an annular reservoir chamber adjacent the other face thereof, with inlet and outlet ports formed in the clutch plate and a radially extending, resilient, flexible valve member mounted on the reservoir chamber face thereof for controlling the flow of fluid medium from the reservoir chamber to the working chamber through the inlet port, in response to the action of a temperature-responsive power unit mounted on the housing.

Abstract: A liquid mixing valve having a single handle for mixing hot and cold water which incorporates a pair of resilient, tube-like squeeze elements for water passage. A pair of cams, controlled by the handle through a linkage arrangement, restrict the cross-sectional area of the squeeze elements thereby regulating the hot and cold water flow rates.

Abstract: Adhesive joining system for joining a plurality of superimposed material layers. An elongated needle-like member is reciprocally and rotatably driven along and about its longitudinal axis so that each reciprocation causes the needle to pass through and be withdrawn from the superimposed layers. After the needle has passed through the layers, at least the outer tip is coated with an adhesive material. The adhesive material itself may be in solid, liquid or powdered form and be either heated or unheated. After coating, withdrawal of the needle from the material layers causes the adhesive on the needle to be deposited on the material through a wiping action caused by the pressure of the material exerted against the needle. Rotation of the needle-like member gathers loose fibers from the material layers and wraps them together in the adhesive to form a reinforced joint.
