Abstract: A hose assembly, preferably a garden hose assembly, including a jacketed tube that is lightweight, durable and versatile. The tube is able to expand longitudinally along the length-wise axis of the hose between hose ends, as well as radially or circumferentially, to an expanded state in response to application of at least a minimum fluid pressure to an inner tube of the hose. Once the fluid pressure falls below the minimum fluid pressure, the hose assembly will contract. The two layer construction of the hose assembly allows for storage in relatively compact spaces, similar flow rates, approximately one-half the weight, and improved maneuverability when compared to conventional hose constructions. In one embodiment the jacket is formed around the tube in a continuous process that welds a material, preferably using hot air, into the jacket. The welded joint forms a region of jacket that is preferably about twice the thickness of the rest of the jacket.

Abstract: A sealing device is provided for use with a fitting. The fitting has circular port and a flow path with a longitudinal axis. A circular port encircles a portion of the flow path opposite the port with the sealing device inserted into the port. The sealing device has a circular top with two opposing surfaces depending therefrom but inclined so the surfaces are closer at the top. A continuous sidewall joins the periphery of the two surfaces. The opposing surfaces are inclined and spaced apart further at the top than at an end opposite the top. A cylindrical hole through the opposing surfaces encircles the flow path during use.

Abstract: The invention is an improved line blind valve which provides absolute positive flow shut-off in piping systems. It uses fluid pressure to separate the seal surfaces while ensuring the end connections do not move relative to each other. Once separated, the blind can be moved easily into either the closed blind position or the open full flow position. The assembly consists of an outer housing, two end pipes and a sliding carrier that allows a blind to be either inserted into the flow or removed by pivoting the blind about a pin.

Abstract: Apparatus and methods for lining a pipe line having a first pipe section in communication with a second pipe section where the first pipe section has an inside diameter greater than an inside diameter of the second pipe section. A transition tube having an outside diameter substantially equal to the inside diameter of the second pipe section and a length substantially equal to or greater than the length of the first pipe section is inverted into the pipe line along with a liner. A resinous material applied to the liner cures and hardens the liner after inversion. The transition tube creates a surface against which the liner can be compressed to help prevent the liner from being overstretched in the wider first pipe section.

Abstract: A method of lining an interior of a pipe in need of repair comprises providing a carrier tube having one or more expandable materials, coating the carrier tube with a binder, securing one or more layers of a fiber-laden material along an exterior surface of the carrier tube with the assistance of the binder. The carrier tube is delivered, together with the at least one layer of the fiber-laden material and the binder, to a targeted location inside a pipe in need of repair. The carrier tube comprises a first diameter while the carrier tube is being delivered to the targeted located inside the pipe in need of repair. The method additionally comprises radially expanding the carrier tube from the first diameter to a second diameter, such that the one or more layers of the fiber-laden material and the binder at least partially contact and/or adhere to an interior wall of the pipe.

Abstract: A flow regulator system includes a flow regulator placed within a fluid flow path to maintain fluid flow therethrough at a desired flow rate. The flow regulator includes a flow washer having an orifice therethrough and a regulator body that receives the flow washer. At fluid pressures between a first fluid pressure and a second fluid pressure, the flow washer rotationally deforms to decrease or increase the size of the orifice, thereby maintaining the desired flow rate. When fluid pressure is greater than or equal to the second fluid pressure, the flow washer contacts a portion of the regulator body to prevent further rotational deformation of the flow washer. In addition, the flow washer radially compresses or expands to increase or decrease the size of the orifice, thereby maintaining the desired flow rate.

Abstract: The present invention is a distributed piston elastomeric accumulator which stores energy when its elastomeric member stretches from its original length in response to the flow of a pressurized fluid. The stored energy is returned when the fluid flow is reversed and the accumulator discharges the fluid as its elastomeric member returns to its original length and moves the piston to its initial position. At least one part of the novelty of the invention is that the accumulator is not subject to radial strain gradients and the accumulator allows for precise pressure and linear position measurements. Accordingly, the invention allows for optimization of the energy strain storage capacity of a given elastomer.
