Abstract: In one aspect there is provided a gas flare comprising a hollow cylindrical member having a bottom end, a top end, a discharge end at said top end, and defining an interior volume having a mixing region. The gas flare further comprises a gas inlet to receive waste fluids, an air inlet to receive and direct air into the interior volume, and an internal riser having an outlet. The mixing region is located above the air inlet and below the discharge end. The internal riser fluidly and sealably connects to the gas inlet and directs all waste fluids from the gas inlet, out through the outlet, into the mixing region.

Abstract: Provided are active materials for electrochemical cells. The active materials include silicon containing structures and treatment layers covering at least some surface of these structures. The treatment layers may include aminosilane, a poly(amine), and a poly(imine). These layers are used to increase adhesion of the structures to polymer binders within active material layers of the electrode. As such, when the silicon containing structures change their size during cycling, the bonds between the binder and the silicon containing structure structures or, more specifically, the bonds between the binder and the treatment layer are retained and cycling characteristics of the electrochemical cells are preserved. Also provided are electrochemical cells and fabricated with such active materials, methods of fabricating these active materials and electrochemical cells and devices containing electrochemical cells fabricated with such active materials.

Abstract: The present embodiments describe methods and apparatuses for protecting the privacy of one or both parties involved in a two-party telephone conversation. The embodiments also use an SMS text network to provide advance, substantial, customizable information to a recipient prior to the joining of two parties in conversation. The embodiments also provide dynamic control over who responds to an incoming call based on multiple criteria. The invention uses SIP various forms of VoIP technology to determine and route calls incoming to a communications system and sends advance notification(s) to recipient(s) prior to the joining the parties for conversation.

Abstract: A method and an apparatus for separating and measuring solids from multi-phase well fluids. The apparatus comprises a separator; an upper solids level and a lower solids level sensor, both connected to the separator; a dump valve operatively connected to the separator; and a control module operatively connected to the dump valve to move the dump valve between an open and a closed position. The upper solids level sensor generates a first signal when the upper level of accumulated solids-within the separator reaches a pre-determined upper level. The lower solids level sensor generates a second signal when the upper level of accumulated solids within the separator reaches a predetermined lower level. The control module receives the first and second generated signals such that upon receipt of the first signal the control module causes the dump valve to open and upon receipt of the second signal the control module causes the dump valve to close.

Abstract: An improved side pocket mandrel having an orientation housing, which in turn has an orienting slot and guide surfaces integrally formed with the orientation housing. The orientation housing is preferably manufactured by machining out of a single piece of metal. The orientation housing is then welded onto the remainder of the side pocket mandrel.

Abstract: The drilling fluid returns from underbalanced drilling are introduced into a separator and a separate gas stream is recovered. The gas stream is cleaned at the well site to remove entrained liquid and particulate solids, to produce gas suitable to be fed to a compressor. The cleaned gas is compressed to re-injection pressure and recycled to the well.
