Abstract: A device method for repairing leaks in pressurized lines, particularly refrigeration lines, without having to drain the fluid from the line, thereby reducing the possibility of refrigerant contamination and/or loss, and providing protection to the environment. The device of this invention is installed over a leak in the line and remains in service for the life of the line.

Abstract: A deployment system and apparatus for running bottomhole assemblies and/or downhole tools in wells, particularly applicable to coiled tubing operations, including pressurized deployment apparatus, a pressure operated connector tool and a multi-functional coiled tubing head.

Abstract: An improved impact absorbing composite comprising protective gear including a shell and a protective layer and a fitting pad comprising a substantially air-tight foam-filled enclosure attached to the protective gear and providing means for adjusting the internal pressure of the enclosure.

Abstract: A composition and method for protecting skin from the damaging of UV or solar radiation, comprising topical application to the skin of a composition containing a yeast cell wall extract.

Abstract: A method for profiling of a gas and liquid producing wells comprising compiling calibration data from measuring instruments within non-in situ test equipment, valuing downhole gas and liquid density, determining average values for downhole instrument measurements and predicting, utilizing the above information, a percent of total gas flow and a percent of total liquid flow at a downhole depth.

Abstract: Method and apparatus for running a mechanical roller arm centralizer through restricted well pipe including roller arms with staggered longitudinal height and limitations upon extension and compression of the arms.

Abstract: Apparatus and method for extending the life of a blade cutting edge including a unit having at least two oppositely charged permanent magnet polar surfaces, the unit defining a receptacle area for holding a blade wherein the oppositely charged polar surfaces and the receptacle area are oriented with respect to each other so that a length of a cutting edge of a blade held in the receptacle would be held in close proximity to at least one polar surface, the plane of that blade would be aligned to coincide with strong magnetic lines of force existing between the at least two oppositely charged polar surfaces and the coinciding lines of force would pass through the cutting edge and turn in the blade.

Abstract: Nozzle, apparatus and method for extinguishing fires that includes applying to a fire simultaneously a first fluid surrounded by a second fluid and that includes a nozzle for discharging a first fluid in a path surrounded by a second fluid.

Abstract: A rotary control valve for controlling fluid flow through a conduit comprising at least one fixed trim element and a rotatable plug element located in the conduit in closely abutting position. The trim element and the plug element have a plurality of ducts extending therethrough. The plug element has at least one transverse duct communicating between at least two of the plurality of ducts. The opening of the ducts on the inside face of the trim registers with the opening of the ducts on a face of the plug.

Abstract: A one-time trouble-free sun visor made from a detachable page of a program, the page having a perforated line that separates a substantially rectangular interior portion of the page from a substantially rectangular exterior portion of the page along three sides of the page. The fourth side of the page forms the front of the visor. The exterior portion forms a continuous band that encircles the head. The interior portion is bisected by a fold line that approximately parallels the front of the visor.

Abstract: A snap-together universal-jointed electrical device comprised of an essentially spherical plug and socket that can rotate and swivel with respect to each other, the plug and/or socket portions being comprised of elastic material that resiliently deforms to permit the plug to be pushed and snapped into, and pulled and snapped out of, the socket, the plug being connected to a bulb with filament and means provided for linking together multiple socket/plug units.

Abstract: A snap-together universal-jointed electrical connection device comprised of an essentially spherical plug and socket that can rotate and swivel with respect to each other while providing for conducting current through the joint on up to three paths, the plug and/or socket portions being comprised of elastic material that resiliently deforms to permit the plug to be pushed and snapped into, and pulled and snapped out of, the socket.
