Abstract: This application relates to an apparatus and method for cleaning drill cuttings recovered from a wellbore. Specifically, the apparatus includes an effective system for handling and washing drill cuttings at a well site to remove hydrocarbon contaminants. The system successively washes hydrocarbon contaminated drill cuttings in organic solvent and water to remove and recover the hydrocarbon contaminates, and produce cleaned drill cuttings that may enable disposal of clean drill cuttings without further treatment.

Abstract: A method for producing special supramolecular assemblies of colorants, in particular cyanine dyes, called J aggregates consists in depositing a monolayer of dendrimers on a support and subsequently in deposing cyanines in solution for forming the organized monolayer of J aggregates. The method can be used for producing a secondary light source for injecting light into a waveguide from a light energy received from a primary light source emitting at different wavelength. The secondary source, which consists of the J aggregates incorporating energy acceptors, can also be integrated into an optical device incorporating the waveguide.

Abstract: The invention relates to a method for producing special supramolecular assemblies of colorants, in particular cyanine dyes, called J aggregates. The inventive method consists in depositing a monolayer of dendrimers on a support and subsequently in deposing cyanines in solution for forming the organised monolayer of J aggregates. Said method can be used for producing a secondary light source (28) for injecting light into a waveguide (24) from a light energy received from a primary light source (30) emitting at different wavelength. The secondary source, which consists of the J aggregates incorporating energy acceptors, can be also integrated into an optical device (23) incorporating the waveguide.

Abstract: A flare tank apparatus for separating combustible gases from a mixture of such gases and a liquid, for example combustible gases in drilling fluid from an oil or gas drill string. The apparatus has an inlet conduit having two or more connectors which permit components of the inlet conduit to swivel relative to each other. The connectors can be loosened to permit swivelling without disassembling the inlet conduit. The swivelling of the connectors permits the free end of the inlet conduit to be moved and positioned for connection to the outlet end of a flare line from the drill string and to be positioned against the holding tank of the flare tank apparatus for convenient transport.

Abstract: A beverage belt adapted to be worn upon a person, said belt including a housing formed of insulative material, said housing including a plurality of spaced apart beverage containing pockets, each said pocket adapted to be closed by a lid, each said lid to be securable upon its respective said pocket by means of a bayonet slot assembly, and the free ends of said belt including securing means to interconnect together the ends of said belt when placed about a person's body.
