Abstract: A diversionary spool assembly for the completion hook up of any type of oil and gas well without the use of an expensive and cumbersome valve tree as a permanent part of the producing well. A single valve tree is provided, and is removably mounted on any one of a group of wells provided with diversionary spool assemblies only when a particular well in that group requires maintenance or remedial work to be performed thereon.Each diversionary spool assembly includes a rigid body having at least first and second passages therein, which body is operatively mounted on a tubing hanger supporting casing head for the first passage to be vertically aligned with a vertical bore in the tubing hanger and a tubing string that depends from the latter.The first passage in the normal operation of the well has a plug removably and sealingly disposed therein.

Abstract: An improved manually operated slide valve, particularly adept for use with a dental aspirator assembly, which valve is characterized by being formed from a number of components removably associated with one another to permit the valve to be disassembled for cleaning purposes. The improved value is also characterized by including means for preventing the slide member to move from an open to a closed position due to variations in pressure within the interior of the valve.

Abstract: A single valve and associated conduits for so operating a reverse osmosis assembly that includes a reverse osmosis cartridge, a reservoir that has a movable barrier therein that sub-divides the interior into first and second confined spaces of variable volume, and a manually operated purified water dispensing valve, so that as the first confined space approaches a filled condition with purified water, the single valve throttles the flow of pressurized feed water to the cartridge to minimize the use of feed water in the operation thereof, with the maximum back pressure to which purified water is subjected in discharging from the cartridge is that due to the weight of reject water in the second confined space, and the membrane in the reverse osmosis cartridge being fast flushed with feed water to remove foreign material therefrom when the purified water dispensing valve is discharging purified water.

Abstract: A top entry electrical transmission safety assembly for removably effecting electrical communication through a tubing hanger, between an above ground electric power supply cable and an electric power receiving cable that extends upwardly from a motor driven submersible pump in a bore hole. The electric power supply portion of the assembly may be removed from the tubing hanger without removing the latter from a supporting well head. The supporting well head has a bonnet removably secured thereto through which the electric power supply cable extends, which bonnet not only serves its normal function, but acts in a safety capacity to prevent the electrical transmission assembly being uncoupled inadvertently to create an electric arc or spark in a hazardous potentially explosive area such as on an off shore platform or island.

Abstract: A reverse osmosis system in which a pair of oppositely disposed, vertically aligned rigid cup shaped bodies that have outwardly extending first flanges are by a circumferentially adjustable band forced into pressure sealing contact with a second flange of a pliable cup shaped barrier to define a reservoir. The barrier when not deformed occupies only a portion of the interior of one of the cup shaped bodies, and requires a minimum of material to define. The uppermost one of the cup shaped bodies supports a single valve that has a pressurized feed water inlet and outlet, and a movable portion that extends into the interior of the upper cup shaped member. Upward movement of the movable portion throttles the rate of flow of pressurized feed water between the inlet and outlet.

Abstract: A purified water dispensing and reject water control device that when operatively associated with a pressurized feed water supplied reverse osmosis cartridge that has purified water and reject water outlets and a tank that is subdivided by a movable barrier into first and second compartments of variable volume that receive purified and reject water and may have same discharged therefrom. The control device includes a single elongate tubular member that actuates first and second valve members that tend to remain in first positions. Purified water from the purified water outlet flows to the first compartment and reject water from reject water outlet flows through a first flow restrictor and then through a second flow restrictor defined by the tubular member to the drain when the valve members are in first positions.

Abstract: A flexible endoscope with a carbon dioxide laser connected thereto for simultaneous viewing and performance of a surgical operation on either exterior or interior tissue of a patient. The laser operates at 10.6 microns, with the laser beam being transmitted through a flexible bundle of drawn fiber optics that are held in adjacently disposed fixed relationship by a flexible sheath. Each laser beam transmitting fiber optic has a core of infra red transmitting true amorphous chalcogenide glass that is clad by a thin flexible film of material having a lesser refractive index. The infra red transmitting glass will preferably have a transmission efficiency of between 38 to 62 percent.

Abstract: A portable tubular metal member straightening apparatus that complies with ecological standards by retaining all foreign solid material displaced from an elongate member as the latter is straightened, recirculates the cooling and wash water rather than spilling it on the ground, and includes a rearward frame extension portion that may be pivoted to an upwardly and forwardly extending position prior to the apparatus being moved over a public highway to bring the apparatus within the length limits imposed on the highway.

Abstract: A turbine for operating on pressurized gaseous products of combustion resulting from the burning of coal and which gaseous products contain fly ash. The turbine includes a housing that supports a power take off shaft on which a rotor is mounted that includes a central circular plate that supports an equal number of first and second ring shaped discs on opposite sides thereof, with the first discs being of substantially greater diameter than the second discs. The second disc cooperates to define a number of first inwardly extending passages therebetween, and the second ring shaped discs cooperate with the first ring shaped discs to form second passages therebetween of substantially less width than the first passages.

Abstract: A packing supporting piston assembly removably securable to an end section of a production casing of a geothermal well, which end section is disposed above a well head. The piston assembly when so mounted has packing in abutting sealing contact with the end section of the production casing and also has packing that is in slidable sealing contact with the interior surface of the expansion spool. The piston assembly is of such structure that the pressures exerted by the packing on the end section of the casing and on the interior surface of the expansion spool are independently adjustable to desired magnitudes. The degree of pressure exerted by the packing on the interior surface of the expansion spool is adjustable after the packing has been disposed within the confines of the spool. The piston assembly in a preferred form includes a circumferentially extending high temperature resisting grease seal situated within the confines of the piston assembly.

Abstract: An energy storing flywheel assembly in which first and second reels are operatively connected by a flexible band, with the first and second reels capable of being rotated by first and second electric motors, and the second reel that can rotate either clockwise or counter clockwise through a clutch mechanism driving a flywheel. The flywheel that stores rotational energy is free to rotate independently of the second reel in a clockwise direction except when it is eccelerated to a predetermined maximum rate by the second reel. Acceleration of the flywheel occurs as the first motor drives the first reel at a constant rate to wind the band thereon. After the flywheel has reached the desired maximum rate of rotation the second reel is rotated to rewind the band thereon. Upon the rate of rotation of the flywheel decreasing to a predetermined minimum the above described operation is repeated.

Abstract: Radioactive and associated chemical contaminants present in uranium mill tailings, for example, are isolated from the environment. A matrix product is formed by combining selected clays and lime with the soluble radioactive and chemical contaminants. The clays absorb the majority of all the contaminants. The lime neutralizes the contaminants and cements the clay silicates and absorbed contaminants. The resulting product is of a matrix-like nature and is reverted into a limestone by the uptake of carbon dioxide in a recarbonization process. The radionuclides and chemical contaminants in the resulting product are converted into insoluble oxides or hydroxides which do not appreciably leach out into the ground water. The release of radon gasses is substantially inhibited in the final product, and the release of radon gasses is virtually nonexistent in the final limestone.

Abstract: A rotary ball valve assembly including an elongate valve body, a first passage having a transverse pin and an elongate key of a rotatable actuator extending therein, a lower valve seat, and a ball member resting on the lower valve seat. A pair of slots are formed on the exterior of the ball member normal to the longitudinal axis of the passage extending therethrough, which slidably engage the pin and key when the ball member rests on the lower valve seat. By rotating the ball member one quarter turn by the key of the actuator the ball member is moved downwardly to compress the elastomeric ring which partially defines the lower seat. An upper ring shaped valve seat is disposed on the first passage above the ball member. The upper surface of the valve seat is in abutting contact with a segmented ring that has an upwardly and inwardly tapered external side surface and an internal side surface that tapers upwardly and outwardly.

Abstract: A water jet propelled boat that includes a source of pressurized air that by a single action control may be delivered to bow and stern portion positioned resilient bags to inflate the same to vary the contour of the wetted portion of the boat to a desired configuration. The boat includes a number of laterally spaced sponsons that have forward bottom surfaces that taper downwardly to merge into substantially straight rearward bottom surfaces on which the boat rides when traveling at high speed. Pressurized air is discharged from the source to flow rearwardly under the boat and impart a lift to the latter. The desired configuration of the bags is one which in combination with the action of the sponsons and the rearwardly flowing bubbles results in the boat moving through the water in a fuel efficient manner.

Abstract: A mechanical transmission with a variable speed ratio that generates two oscillatory rotary motions that may have the velocities thereof selectively increased or decreased by concurrently increasing or decreasing the effective lengths of a pair of crank arms, with one of the oscillating rotary motions being rectified by two over riding clutches to become a pulsating rotary motion in a constant direction, and the pulsating and oscillating rotary motions thereafter being combined by a differential to result in a fixed ratio of output to input velocity for each setting of the pair of crank arms.

Abstract: An apparatus in which a current of air is directed across a surface of a substance of unknown identity to have molecules of the latter entrained therewith. The molecules are attracted electrostatically to the surface of a piezoelectric element to cause microscopic vibrations of the element. The microscopic vibrations result in the piezoelectric element emitting a minute voltage at a like frequency that is subsequently amplified. The amplified voltage is used to produce pulsed sound waves that are directed onto a resilient diaphram to vibrate the latter, and the mechanical energy of the diaphram being transferred to the piezoelectric element to amplify the voltage emitted. The amplified voltage is of sufficient magnitude to actuate an oscilloscope or recording computer to provide a distinctive pattern that is used to identify the unknown substance.

Abstract: An improved fuel burning assembly particularly adapted for use with a boiler having a fire box situated below an array of boiler tubes. The assembly discharges a number of spaced rotating streams of minute droplets of a flowable fuel both laterally and longitudinally into the fire box to intermix with a stream of air that is moving rearwardly therein. The fuel air mixture when burning blankets substantially all the boiler tubes with a sheet of flame. Due to such flame contacts substantially all of the boiler tubes are heated uniformly thereby, rather than only a portion of the boiler tubes being contacted by the flame as occurs in a boiler when a conventional burner assembly is used. As a result of the flame distribution and uniform heating of the boiler tubes, an increased thermal efficiency is attained in the operation of the boiler on which the burner assembly of the present invention is used.

Abstract: A device for automatically igniting the oxygen-acetylene mixture flowing from a welders torch when the tip of the torch is brought into pressure contact with an elongate resilient member that forms a part of the invention.

Abstract: An internal combustion engine in which first and second elongate blocks of identical structure are axially aligned and held in longitudinally spaced relationship by a generally cylindrical connector. The first and second blocks cooperate to define a number of axially aligned cylinders, each of which has a double ended piston slidably mounted therein, and each of which piston supports a pair of cam engaging members. A drive shaft is rotatably supported in the first and second blocks, which drive shaft supports a force receiving cam that is engaged by the pairs of members on the pistons, with the cam situated within the confines of the connector.
