Abstract: A valve assembly is disclosed in two embodiments for selectively controlling pressurized fluid flow to operate a fluid operated working cylinder and piston. The valve assembly includes a valve body, groups of three bores operably paired in the body, biased plunger valves interposed in each of the bores, and a separate passage inter-connecting between each bore group on one side of the interposed valves. There is provided a pressure connection to a first one of the bores in each group on the other side of the interposed valves away from the passage and a first side cylinder connection to a second one of said bores in one of each pair of groups. The other cylinder connection is provided to a second one of the other one of each pair of groups of three bores while an exhaust connection is provided to a third one of the bores in each group.

Abstract: A system and method for repair of leaking storage tanks containing fluids which contaminate ground water has been devised requiring reduced funding which will make it economically feasible for repair of all old tanks suspected of being potential leakers, thereby protecting the public and environment from future severe hazards.All internal appurtenances are removed from the tank before it is gas freed and fitted with a new combination manway and appurtenances access. All tank openings originally utilized by appurtenances are plugged liquid tight except for the tank vent system. A flexible fluid tight containment means is formed to the tank interior shape and contains an opening edge which is assembled as a fluid tight gasket seal between the flange cover of the new access. All internal appurtenances are relocated to extend through the new access.

Abstract: A solar energy collector comprising a parabola shaped mirror formed a plurality of flexible reflective film strips stretched over a plurality of supports being arranged to position the film in a parabola shape. The supports are held in place by a plurality of trusses. The mirror is pivotally secured to a support assembly whereby the mirror can be maintained at the same relative position to the sun. Positioning of the mirror is controlled by an energy rays tracking device. The supports are adjustable such that light and infrared energy rays striking the film between the supports are reflected to the focus of the mirror around which a collector assembly is located. The collector assembly comprises a surface coated with a black substance which is capable of maximum heat absorption from the light and infrared energy rays; and, a contained fluid passing in contact with said surface absorbs and transfers the heat in order that useful work can be obtained therefrom.

Abstract: A fluid energy convertor comprising a turbine having a cylindrically shaped interior whose exterior surface is exposed to a fluid front which is naturally accelerated while flowing around same creating a current of fluid which is contained only within a portion of a cylindrically shaped passageway, located around the outside of said cylindrically shaped interior, where contact is made between said current of fluid and a series of turbine vanes causing their movement and providing an active force on same which is transmitted by way of the turbine's structure to a centrally rotating spindle and other means for providing useful work. Multiple automatically controlled adjustable louvers assist in directing the fluid front into said passageway and in containing said current of fluid within said passageway with said louvers being adjustable to either speed-up or throttle said current of fluid as required for maximum work within limits dictated by the fluid velocity, turbine size and convertor structural strength.

Abstract: An energy rays tracking device including a receiver for fixing a position relative to the direction of maximum energy rays, a prime mover for maintaining the alignment of the receiver and an energy rays user, an energy rays tracker for controlling the power to the prime mover in response to the receiver, a timed tracker for controlling the prime mover when the energy rays tracker is not functioning due to energy rays being too diffused, an energy sensitive element for detecting the presence or absence of energy rays, and a power controller responsive to the energy sensitive element for repositioning the receiver and the energy rays user for the following period of tracking is disclosed. The receiver includes an enclosure which only allows a selected pattern of direct rays to penetrate into the enclosure. A razor sharp edge at the opening of the enclosure maintains the outermost direct energy rays undiffused.

Abstract: A solar energy collector comprising a circular paraboloid mirror formed from a plurality of flexible reflective film strips stretched over a plurality of concentrically arranged support rings being arranged to position the film in a circular paraboloid. The support rings are supported by a plurality of trusses. The mirror is pivotally secured to a lower support assembly which is rotatably about an azimuth bearing and rotatable for elevation through a pivot point which passes through the mirror. The support rings are adjustable such that light rays striking the film between the support rings is reflected to the focal point of the mirror wherein a solar collector is located. The solar collector comprises a plurality of helically arranged tubes coated with a black composition of plaster of paris and carbon black to maximize collection of heat to the fluid passing through the tubes. The nest of tubes are hermetically sealed to minimize losses from convection.
