Abstract: A process for the ultrasonic treatment of mined sand proppant for hydraulic fracture treatment, the process comprising the steps of pumping sand particles in an aqueous fluid to an ultrasonic device operating at a suitable frequency and a suitable power range. The sand particles remain at a proximity to the ultrasonic device for a first predetermined period of time to remove contaminants from the sand particles.

Abstract: A diamagnetic levitation system having an open torus magnet segment with a pair of arms extending from a central base. The ends of the arms form a gap. The arms are superconducting magnets and the base is an electromagnet. The magnet segment creates a planar magnetic field which forms a flat ellipse as the planar magnetic field crosses from one arm to the other and which is positioned only across the gap. The electromagnet oscillates the planar magnetic field. The magnet segment levitates a diamagnetic object within and/or above the gap. A plurality of magnet segments can be arranged in series to form a levitation system of defined length. The magnet segments are rotatable so that the planar magnetic field may be tilted.

Abstract: A diamagnetic levitation system for levitating users to a levitation surface upon which they may engage in sports and other activities under relatively weightless conditions in a dome-shaped structure. Superconducting magnet segments are connected in series to form a superconducting magnet segment assembly. A plurality of these superconducting magnet segment assemblies form the diamagnetic levitation system. The diamagnetic levitation system not only generates the levitation surface to which players or other users are levitated but also confines them within the boundaries of the levitation surface. The magnetic field strength of the diamagnetic levitation system is self-terminating so that spectators viewing the players are not affected by the levitating magnetic field.

Abstract: A diamagnetic levitation sphere having concentric superconducting coils encircling a hollow sphere. The inner surface of the sphere is lined with a 3D visual display screen. Users in carbon fiber suits are positioned within the hollow sphere by entering the sphere at its bottom end, standing on an elevator platform, and then being elevated up towards the center of the sphere. The superconducting coils are energized, the users are levitated while on the elevator platform, and then the elevator platform is lowered to the bottom of the sphere, closing the sphere. The users then float freely in space and can participate in a full emersion space ride game. The diamagnetic levitation sphere can also provide users unique experiences in physical training, therapy, entertainment, and education.

Abstract: A method for reducing or substantially eliminating oxides of nitrogen from an effluent gas stream, that includes providing a source of ultraviolet radiation with a precise wavelength, adding ammonia or an ammonia based reagent to the effluent stream, upstream of the ultraviolet radiation source, controllably operating the ultraviolet radiation source to irradiate the effluent stream flowing in the duct and substantially reducing or eliminating oxides of nitrogen by promotion a reaction of ammonia with the oxides of nitrogen to produce N2 and H2O, and also thereby destroying any surplus ammonia. This process can also be modified to oxidize carbon monoxide and VOC's to CO2 and H2O.

Abstract: A tool having a tube string made of inner and outer coaxial tubes, and a dewatering natural gas-assisted pump at the bottom of the tube string. The pump includes a nozzle, an eductor, and a diffuser. The nozzle has a central inlet and a number of primary angled gas outlets, each opening to a gas supply space between outer and inner pipes, and to the interior of the inner tube. These angled outlets allow the gas to accelerate, contributing to a venturi effect in the tool. A fluids/debris/etc. mixture moves from the nozzle ring to the inwardly inclined eductor, which causes the mixture to converge. Then, the mixture diverges along the outwardly inclined diffuser to the inner pipe in which the mixture moves to the surface. At the convergence/divergence area, the venturi effect is enhanced. That is, a number of secondary outlets, formed in the diffuser, introduces additional gas from the gas supply space to the interior of the inner tube.

Abstract: This invention provides an apparatus and process for producing heavy crude oil from a subterranean formation penetrated by a well bore. In accordance with the process, an aqueous alkaline chemical solution is introduced into or formed in the well bore penetrating the formation. The aqueous alkaline chemical solution mixes and reacts with produced heavy crude oil in the well bore and ultrasonic waves are emitted into the mixture whereby an emulsion is formed. The viscosity of the formed emulsion is less than that of the crude oil or the crude oil and water mixture flowing into the well bore which allows the oil to be more efficiently pumped to the surface and transported for further processing.

Abstract: The present invention provides methods and apparatus for enhancing the production of liquid hydrocarbons from a subterranean formation penetrated by a well bore. The methods basically comprise placing one or more electric powered sonic energy transducers actuated by magnetostrictive actuators which preferably have drive rods formed of terfenol alloy in the well bore, and causing sonic energy to be emitted from the transducers in the form of pressure waves through the liquid hydrocarbons in the well bore and/or in the formation thereby causing the liquid hydrocarbons to flow into the well bore and to the surface more freely.
