Abstract: A system and method of cooling a steam turbine having internal moving components to a predetermined temperature by controlling a flow of nitrogen through the turbine, thus decreasing the downtime associated with maintaining the turbine. This provides a more efficient and cost effective method of operating a power plant.

Abstract: A safety valve (100) replaces an existing safety valve (102) in order to isolate a production zone from a tubing string when closed. Preferably the safety valve (100) includes a flow interruption device (106) displaced by an operating conduit extending from a surface location to the safety valve (100) through the inside of the production tubing. A by-pass conduit (150) allows communication from a surface location to the production zone through the safety valve (100) without affecting the operation of the safety valve (100).

Abstract: A roof stowage system includes a support having a first end and a second end opposite the first end. The second end is pivotably coupled, at least indirectly, to the roof. A lift is coupled to the support and operable to selectively cause the support to pivot between a first position and a second position. The support is generally parallel with and adjacent to the roof when in the first position. The first end of the support is generally adjacent to a floor when in the second position.

Abstract: A method and apparatus for inserting a small diameter continuous hydraulic conduit or capillary tube down a well bore is presented. The methods and apparatus allow either the injection of chemicals to enhance production of oil and gas, or to provide a conduit for production up through the small diameter tubing in marginal wells, into a hanger below a well valve to permit its removal from below the valve if the valve should be required to be closed and its reinsertion without pulling the tubing from the well bore.

Abstract: A method for teaching stringed instrument students how to play sheet music through the use of colored fingering numbers. This method assists the user in knowing which finger to use on which string as they play instrumental music. It also indicates which position their hand should be in as they play sheet music. Numbers correspond to which finger should be used to play a particular note. Separate, distinctly identifiable colors are assigned to notes that should be played on a particular string in a particular position, and are visually displayed as colored fingering numbers that indicate which string and in which position the user should play the fingered notes on.

Abstract: The present application is directed to a wrist covering designed to be worn over the gloved hand and arm-sleeve of a user. The wrist covering comprises a flexible, generally tubular member extending from a first opening, designed to fit around the forearm of the user, to a second opening, designed to fit around the hand of the user. The first opening has a larger circumference than the second opening. The wrist covering further includes a thumb aperture in the tubular member proximate to the second opening. A first fastener is positioned on the tubular member in a manner that allows tightening of the tubular member around the user's hand. A second fastener is positioned on the tubular member in a manner that allows tightening of the tubular member around the user's wrist. A third fastener is positioned on the tubular member in a manner that allows tightening of the tubular member around the user's forearm. A method of making the wrist covering is also disclosed.

Abstract: A coiled tubing connector having a body and a plurality of entry or transition sections connected to the body wherein the connector has a low cycle fatigue life of at least 30%, more preferably at least 50% of the coiled tubing. A preferred embodiment contains two shoulders that form an annular void, a plurality of centralizers about an exterior of the body, and/or a plurality of elastomer molds separating the centralizers. The connector is preferably longer than the connectors of the prior art and is a composite of fluoroplastics or aluminum alloys.

Abstract: A frameless inflatable pontoon boat in which the pontoons and connecting section have a generally flat top and a generally flat bottom. Sufficient rigidity is achieved in the inflatable connecting section and the pontoon by the use of internal thread connections between the top surface and the bottom surface. The internal thread connections confine the inflated shape of the pontoons and connecting section to a flat shape.

Abstract: A method and apparatus for disinfecting water using ultraviolet light. An apparatus with an ultraviolet light source is floated in a water container such that the ultraviolet light source is suspended beneath the water surface and is capable of emitting ultraviolet light into the surrounding water.

Abstract: An improved well completion system for completing two or more separate production zones in a well bore during a single downhole trip is disclosed. The improved completion system comprises a completion assembly comprising two or more production zone assemblies and a completion tool assembly. Each production zone assembly may comprise an automatic system locating assembly and at least two inverted seal systems for sealing against the tool assembly.

Abstract: A hydraulic sleeve valve is disclosed that comprises a bypass relief system that provides an indication that the valve has reached a predetermined position, such as, for example, the fully opened or fully closed condition. The bypass relief may also provide a valve control fluid circulation function to filter or otherwise manipulate the control fluid. Also disclosed are flow port alignment systems that maintain the valve flow ports in predetermined relationships.

Abstract: The invention is a protective cover for a buckle, for protecting a vehicle from the buckle, which may be used with a strap to secure loads such as kayaks, rafts, and canoes to the vehicle roof. The buckle and its attached strap can be inserted into the protective cover, and can later be removed from the protective strap if desired. The release lever of the buckle is covered by the protective cover, and is depressed by pressing down on a portion of the protective cover.

Abstract: A mechanical flow control device is provided that allows flow of production fluids along an annular path and across an valve body. A sliding sealing member can be mechanically transitioned between an opened flow position and a closed flow position as desired. The mechanical flow control device may be combined with one or more interventionless flow control devices.
