Abstract: Disclosed is a device for causing turbulent flow in a tank assembly that includes, inter alia, a base portion and a vane element that extends in an axial direction from the base portion. The vane element has a curved surface formed at a distal end thereof which is adapted and configured to redirect fluid traversing the device axially in a non-axial direction. Still further, a plurality of shoulder elements extend radially outward from the axis of the vane element and are adapted and configured for limiting that axial insertion of the device into a fitting associated with the tank assembly. In an embodiment of the present invention, the vane element includes lateral edges which are adapted and configured for press-fit engagement with an inside diameter of the fitting associate with the tank assembly.

Abstract: A pressure vessel with a protective jacket disposed thereon, wherein the vessel is formed of a metal liner surrounded by a layer of thermoplastic composite filament winding and a protective jacket disposed thereon that facilitates stacking and portability of the vessel, while also providing sufficiently sized openings for visual inspection of the composite layer integrity.

Abstract: A non-metallic, diaphragm-type tank assembly for use with a pressurized water system is disclosed. The tank assembly comprising a non-metallic outer body; a non-metallic inner shell assembly, including an upper portion and a lower portion, that is contained by the non-metallic outer body; and a diaphragm that is structured and arranged about the upper and lower portions of the inner shell assembly to separate said inner shell assembly into a water portion and a pressurized gas portion. Preferably, the diaphragm comprises a resilient, non-porous material and includes a bead portion comprising an annular ring that is convex on an inner side and concave on an outer side at its outer periphery. More preferably, the bead portion is removably secured to the overlapable end portion of the lower portion of the inner shell assembly by a clamping system that comprises an inner clamp hoop and an outer band.

Abstract: An in-well aeration device which includes a water pumping section disposed within the well for drawing water from the well, an aerating section operatively connected to the water pumping section for drawing air into the well and subsequently injecting the air into the well water above the level of the water pumping section, and a motor operatively connected to the water pumping section and the aerating section for operating both sections simultaneously.

Abstract: A method of aerating a well having a well pump positioned therein is disclosed which includes the steps of positioning an air diffuser within the well above the level of the well pump, determining the recovery period for the well, and supplying air to the diffuser to aerate the well water, for the well recovery period, upon activation of the well pump to remove or otherwise release contaminants from the well water.

Abstract: A mobile prepressurized fluid storage tank is disclosed where the compressed air, completely separated from the fluid by a flexible diaphragm, dispenses the fluid under pressure, e.g., into an engine. The prepressurized diaphragm-type fluid storage tank is initially charged with a gas on one side of the diaphragm. A connector on the other end of the tank is connected to the fluid pumping system. Fluid is pumped into the tank until a predetermined pressure is reached and then the fill valve is shut off. A second connection attached to a bottom system connection has a hose. At the end of the hose there is a fluid shut off valve. Dispensing of the fluid takes place through the fluid shut off valve. The prepressurized fluid storage tank is mounted on a frame that contains wheels for mobility.

Abstract: A valve for a pressurized container includes a valve housing having a central bore and a port in the for connection of a nozzle. Preferably, the valve has a unidirectional stepped valve housing. In the housing is a central bore that includes an upper portion, lower portion and a middle portion. The lower portion is narrower than the middle portion which in turn is narrower than the upper portion. The port is provided in the middle portion of said housing to facilitate connection of a nozzle to the valve. The valve has a t-stem with a lower end having a key-way and a cavity for receiving the upper portion of the valve seat. The valve seat provides the primary valve seal when the valve is closed. The upper portion of the valve seat has a geometry for engaging the t-stem to provide a locked assembly.
