Abstract: A portable power operated apparatus that may be positioned adjacent a first stack of lengths of oil well tubing having collars screwed on first ends thereof. The lengths of tubing are subsequently removed from the first stack onto the apparatus. Each length of tubing after being disposed on the apparatus is power rotated with the collar being removably held stationary relative to the tubing to separate the collar therefrom. The collar after removal is inspected, and if found satisfactory for further use is directed to the rearward end of the apparatus. The collar at the rearward end of the apparatus is removably gripped in a reverse position and screwed onto the second end of the tubing by rotating the latter. The length of tubing with collar attached is then lifted by the apparatus and moved to a second stack of tubing where it remains until again needed.

Abstract: A cable stripper, including an elongated handle, a conventional single edge razor blade supported in each opposite end of the handle, one of the blades having an exposed corner of its cutting edge, while the other blade has a portion of its cutting edge inside a groove formed on the handle.

Abstract: A portable auctioneer's podium assembly movably supported on casters that may occupy either a first or second position, which assembly when in the first is defined by a vertically disposable elongate structure that supports a shelf on which the auctioneer may rest papers and the like, and an elevated platform rearwardly of the structure on which the auctioneer may stand to look down on a crowd to spot bidders. The platform is hingedly connected to the structure and may be pivoted into the latter when the assembly is disposed in a second position to occupy less space than in the first position to facilitate the transportation of the assembly from one auction site to another. Fastening means are provided to removably secure the platform in the second position.

Abstract: An elongate container for drinking water formed from a resilient laterally deformable polymerized resin. The container has a wide mouth neck that has first coarse threads on the exterior thereof that are threadedly and frictionally engaged by second coarse threads on the interior of the combined closure and drinking water dispensing assembly. The assembly has a water dispensing tube projecting outwardly therefrom through which a jet of drinking water is discharged when the container is squeezed by an athlete. The assembly rotatably supports an inverted cup shaped guard, which guard is free to rotate thereon. Visual insignia are provided on the guard to axially align first and second pairs of openings in the closure and guard to permit an elongate rigid member to be extended therethrough, and used to twist the closure assembly into binding frictional engagement with the neck. The elongate member when removed from the openings allows the guard to rotate freely on the closure.

Abstract: A handlebar structure particularly adapted for use on motorcycles employed in racing over rough and uneven terrain. The grips and the angulation of first and second oppositely disposed cross members structures are manually adjustable to suit the riding characteristics of a particular rider. A combination of resilient pads and a fluid containing shock absorber cooperate to minimize the shock transmitted to the arms of a rider in traveling over a rough and uneven course. In an alternate form of the invention resilient cross members serve to minimize the shock transmitted to a rider as his motorcycle traverses an uneven course.

Abstract: A portable, power-driven device capable of being carried by an operator to force stiff but bendable fishing tape through an electrical conduit until engageable means on the free end of the tape project from the conduit. The free end of a length of wire is removably secured to the engageable means, with the device now being operated to retract the tape into a storage reel that forms a part thereof. As the tape is retracted, the wire is drawn through the conduit. The device is of such structure that it may exert a pull on the wire of a far greater magnitude than that possible by a single person, and as a result extremely long lengths of wire may be drawn through a conduit or other elongate confined space.

Abstract: An improvement to a grain drying and storage structure which reduces moisture condensation on the inside of the walls of the grain drying structure by forcing heated air out through a peripheral opening at the top of the wall of the drying structure into a space between the wall and an external shell, thus heating the wall, and which allows moisture that condenses under the roof of the grain drying structure to drain to the outside of the grain drying structure so that it does not drain down onto the drying grain.

Abstract: A substantially all wood, lightweight, inexpensive tool that includes two elongate laterally adjustable base members that have longitudinal slots therein that are removably engageable by dowels to grip marginal edge portions of a sheet covering material therebetween. The span of covering material extending between the base members may be coverite, silk, monokote, solar film, silk span tissue, 3/4 inch fiberglass or the like. The tool when so containing the covering material is caused to overlie a wing or other desired portion of a model airplane that rests at a sufficient elevated position on a flat horizontal surface that the base members do not contact the latter; and the weight of the tool tensioning the span of covering material so that the latter extends over the leading and trailing edge of the wing. The span of covering material may be heat sealed or otherwise secured to the wing or model aircraft component.

Abstract: A bladeless pump that includes a housing that defines a circular confined space of substantial width into which either a single phase fluid or multiphase fluid is sequentially introduced through a centrally disposed inlet in a first side of the housing to be subjected to boundary layer rotational drag by at least one substantially smooth disc that rotates in the confined space intermediate the first and second side pieces of the housing and parallel thereto. The pump is capable of pumping a multiphase fluid such as that from a geothermal well that includes water, dissolved solids, steam and gas vapor, or a fluid in which the outer phase is water and the inner phase may range through such diverse materials as particled coal, marine animals such as fish, shrimp and crustaceans, and edibles that include fruits, vegetables and berries, as well as metallic objects of which steel ball bearings is an example. The pump has the capability of pumping beer without appreciably frothing the latter.

Abstract: A valve supporting tubular assembly capable of being mounted on a geothermal well head, with the tubular assembly of such structure that an internal plug that supports resilient packers and has circumferentially extending teeth defined thereon may be removably locked in a first position to seal the interior of the tubular assembly above the outlets to the valves, the plug may also be moved longitudinally in the tubular assembly to scrape solids deposited on the interior surface thereof by geothermal fluids, and the plug may also be moved to a second position to pack off the interior of the tubular assembly below the valve outlets to permit the valves to be moved or maintenance work performed thereon without shutting down the geothermal well. In addition, the plug is provided with means to equalize the pressure above and below the plug in the tubular assembly to permit the plug and components situated thereabove to be removed from the tubular assembly.

Abstract: A hydraulically operated downhole pump that is connected to or disposed in a string of tubing, and when operated by pressurized oil from the ground surface, is capable of discharging production fluid, gas, and pressurized oil from the well either separately or in desired combinations thereof. The pump includes an elongate housing preferably of such transverse cross section as to be longitudinally movable through a tubing string, with the pump including universal joint connected upper and lower helical screws that rotate in slidable sealing contact with upper and lower double threaded resilient stator blocks secured to the interior of the housing. As pressurized oil is discharged into the upper end of the housing the upper helical screw and associated stator act as a motor to drive the lower helical screw relative to the lower stator block.

Abstract: An inexpensive, sanitary, disposable assembly for enveloping the tail of an animal that is particularly useful in breeding and foaling. The assembly includes a guide ring that supports an elongate sleeve in overlapping folds, which ring may have the tail of the animal extended therethrough to dispose the ring adjacent the tail bone of the animal. A first end of the sleeve is removably secured to the tail bone, with the guide ring thereafter being moved away from the tail bone, and the sleeve peeling from the guide ring until none remains thereon. The guide ring is then discarded and the outer second end of the sleeve knotted for the sleeve to envelop the tail, preferably when the tail is in a doubled over configuration.

Abstract: The invention is a method of producing dispersions of aqueous globules in an aqueous medium. The aqueous phases are rendered insoluble or immiscible in one another by the presence in separate phases of colloidal ionic reactants, preferably macromolecular polyelectrolytes, which are opposite in charge. The dispersed globules are larger than colloidal dimensions, and may be as large as one-half inch or more in length. If desired, they can be separated from the continuous medium and dried as discrete particles. When one or more of the aqueous phases are different in color, the compositions are useful in producing multicolor coatings, ceramic glazes, and fibrous webs. The dispersion is unique in that each of the dispersed globules possesses such plasticity and coherence that it may be subjected to substantial shear without subdividing. The dispersion when the globules are colored may be applied to a desired surface to impart either a first or second decorative appearance thereto.

Abstract: A golf club shaft of such structure that the stiffness thereof is controlled by rotatably adjusting the shaft relative to the striking surface of the club head asociated with the shaft. The shaft is also of such structure that the torque developed on the club head upon impact with a golf ball is distributed over the entire length of the shaft, and the club head as a result thereof having a minimum tendency to rotate relative to the arcuate path through which it travels. Due to the two above-mentioned operational advantages a club embodying the shaft permits the user to impart maximum kinetic energy to the ball impacted thereby and the ball having a minimum tendency to deviate laterally in flight from an extension of the arcuate path through which the golf club head moves. The invention also includes a method of making the shaft.

Abstract: An underwater pile driver assembly that includes a vertically disposed tubular housing that may slidably engage the upper end portion of a pile, with the housing having an upper open end, and the housing supporting an anvil that may be placed in abutting contact with the pile. An impact imparting ram is slidably and sealingly mounted in the housing, and may be successively raised to a first position therein. Pump means are provided to successively evacuate water from the interior of the housing between the ram and anvil. After each evacuation the ram is released to be forced downwardly by the hydrostatic head imposed on the upper surface thereof to impact the anvil, with the force imparted to the anvil being transverse to the pile to drive the latter downwardly. The greater the distance of the upper end of the housing from the surface of the water, the greater will be the magnitude of the downward force exerted on the pile each time the ram impacts the anvil.

Abstract: A power driven device for twisting a crown cap from a neck of a bottle as the cap and neck are inserted into a cup shaped driven head that pivotally supports a number of cap engaging knives. The head contains a spring loaded member that moves the loosened cap outwardly with the neck, as the latter is withdrawn from the head. A sring mounted on the interior of the head separates the cap from the neck should the cap tend to cling to the latter.

Abstract: A high lift check valve resistant to the flow of abrasive containing fluid therethrough, which valve may be transformed to also act as an excess fluid control valve.

Abstract: In the method of the present invention, the slurry as it flows from a source thereof is pre-rotated prior to entering a circular vertical confined space that has a cut water discharge in the upper portion thereof. The pre-rotating slurry upon entering the confined space is subjected to the rotary action of first and second laterally spaced circular surfaces that have a number of laterally spaced ring-shaped surfaces situated therebetween. The circular surfaces and ring-shaped surfaces are power driven and rotate concurrently as a unit. As such rotation takes place, the boundary layers of slurry that adhere to the circular surfaces and ring-shaped surfaces are sheared from the balance of the slurry, and the slurry in the confined space rotating as a result thereof. As a result of this rotation, the slurry in the confined space sequentially discharges through the cut water to be replaced by pre-rotating slurry that enters the confined space.
