Title: Cogeneration of electricity and liquid carbon dioxide by combustion of methane-rich gas
Inventor: MARKBREITER STEPHEN J
IPC: C01B32/50
Filed: 1990-05-02
Granted: 1993-11-09
Abstract: COGENERATION OF ELECTRICITY AND LIQUID CARBON DIOXIDE BY COMBUSTION OF METHANE-RICH GAS                 ABSTRACT OF THE DISCLOSURE     Cogeneration of electricity and liquid carbon dioxide is conducted by combusting methane-rich gas to power a gas turbine and a steam turbine; each turbine drives an electric generator.  Carbon dioxide is separated from the combustion products by an amine absorption system to which heat for re-leasing absorbed carbon dioxide is supplied by steam drawn from the steam turbine.  Some of that steam is used to pro-duce refrigeration with an ammonia absorption refrigeration unit.  The refrigeration is applied to the separated carbon dioxide to liquefy it.  Fractionation to yield purified liquid carbon dioxide is easily achieved and saleable re-frigeration is another optional product of congeneration.

Title: Optimized offset strip fin for use in compact heat exchangers
Inventor: SO ALLAN K
IPC: F28F1/10
Filed: 1991-04-15
Granted: 1995-04-18
Abstract: An offset strip fin for use in compact automotive heat exchangers is disclosed.   The offset strip fin has multiple transverse rows of corrugations extending in the axial direction wherein the corrugations in adjacent rows overlap in order that the oil boundary layer is continually re-started.   The fin dimensions have been optimized in order  to  achieve  superior  ratio  of  heat  transfer  to pressure drop along the axial direction.  In one aspect, an compact concentric tube heat exchanger has an offset strip fin located in an annular fluid flow passageway located between a pair of concentric tubes. The preferred range of lanced lengths is determined to be between 0.035" to 0.075" for periodically developed flow.   Maintaining the lanced length in the regime of periodically developed flow is advantageous  in  that it  gives  a higher heat  transfer coefficient than is achievable with fully developed flow.          This also provides the added advantage that variations in the shape of the flow passages from the rectangular do not impact negatively on the heat transfer.

Granted: 1996-10-15
Abstract: An elongated resilient wedge and spool retaining structure longitudinally extends through generally aligned openings formed in a replaceable excavating tooth point, and an adapter nose portion received in a tapered socket within the tooth point, to captively hold the tooth point in place on the adapter nose. The retaining structure includes a tapered spool member having an enlarged side portion received in the tooth socket and blocking removal of the spool member, and a tapered wedge member driven into the tooth and adapter openings to a position in which longitudinally extending series of ratchet teeth on facing sides of the spool and wedge members are intermeshed and releasably lock the structure in place within the tooth and adapter assembly. A recess formed in a nontoothed side of the wedge member receives a locking member that forcibly bears against a surface portion of the adapter nose opening and is movable into the recess in a manner compressing a plurality of elastomeric members therein. The elastomeric members are maintained in compression and exert resilient reactive forces that simultaneously act to draw the adapter nose into the tooth socket and forcibly hold the spool and wedge member ratchet teeth in intermeshed engagement with one another. A removal tool may be driven into a longitudinal passage extending through the retaining structure, centrally through the intermeshed series of ratchet teeth, to laterally separate the wedge member from the spool member and thereby facilitate the removal of the installed wedge member.
