Abstract: A cone type control valve comprising a cone shaped valve plug movably retained in an similarly shaped opening of a valve housing having horizontal inlet and outlet ports and wherein any reciprocal movements of the conical plug can control fluid flow from the inlet to the outlet port. The cone shaped opening furthermore has cavities located perpendicular to the ports, capable to accelerate and de-celerate fluid passing between the two ports.

Abstract: A differential pressure sealing device for use with ball valves that utilizes the pressure of the fluid being communicated in a piping system to increase the sealing force created by the sealing device. Fluid being communicated through a ball valve is provided to a sealing device that includes some type of element for creating a bias force. The pressure of the fluid being communicated increases the sealing pressure created by the sealing device. In this manner, the bias force created in the sealing device benefits from the pressure of the fluid being communicated to enhance the sealing when used with a ball valve or similar component.

Abstract: An anti-cavitation control valve suitable to reduce high pressure in a fluid control system without creating cavitation or high noise levels, comprising a housing having one fixed and one movable cylinder, both having equally spaced holes that can be opened or closed simultaneously.

Abstract: A cradle type bed for immobile patients, comprising a bed frame supporting a curved center portion being able to be tilted around the longitudinal axis of a supine patient and its center of gravity in order to relief constant pressure points between the skin and a mattress.

Abstract: A variable resistance device, suitable for pressure reduction in fluid control systems, comprising a housing with a pair of perforated tubes motivated to slide against each other in order to vary the amount of flow area exposed in such perforations, and wherein a cam and lever system causes sliding motion of one of the tubes.

Abstract: A device capable of dividing the difference between inlet and outlet pressures in a pressure reducing system, in a given proportion, between a conventional control valve and a regulating device, wherein the latter comprises a cylindrical housing being attached to said control valve, having perforations and an interior sliding piston featuring similar perforations, and where the piston is motivated by an inlet pressure pressurized diaphragm, whose force is counteracted by a compression spring.

Abstract: A double eccentric butterfly valve having a housing, a shaft, a seat ring, and a vane, wherein the seat ring is radially flexible to conform to the spherical rim of a vane having one of the rim portions extending in width in order to improve the dynamic torque characteristics of the valve; means to prevent expulsion of the shaft from the vane due to hydrostatic forces of fluid passing the valve.

Abstract: The invention relates to vanes used in butterfly valves utilized in fluid control systems requiring special relationships between passing fluid and vane rotation and furthermore can provide leak proof shut-off when in the closed valve position and due to the extended contact length between the vane and the valve bore assures low opening friction. The invention furthermore features a shape that greatly reduces the customary high dynamic torque created by fluid suction effects on a vane when in the open position.

Abstract: A toilet leak preventing system comprising a conventional toilet, having attached thereto a sensing device able to detect sound or vibration from a leaking toilet, and having means to close the water supply to the toilet after a predetermined time interval.

Abstract: A ship propulsion system comprising a mechanism to convert mechanical power into a swinging, paddle-like action of a fin-like plate, located at the exterior of a vessel, thereby mimicking the propulsion made by the tail of a fish.

Abstract: The invention relates to offset-type ball valves utilized in fluid control applications requiring special relationships between the amount of passing fluid and the camming motion of a spherical element; and furthermore can provide leak proof shut-off when in the closed position. My invention, due to the absence of sliding plug seals, offers very little friction, making it ideal for throttling applications as part of automatic control systems.
