Title: Live well deployment of electrical submersible pump
Inventor: COX DON C
IPC: E21B33/068
Filed: 2000-02-24
Granted: 2008-08-12
Abstract: A method for installing a submersible pump assembly that allows deployment in a live well under pressure. In some of the embodiments, a pressure barrier is installed in the well lower than a length of the submersible pump assembly. The submersible pump assembly is lowered on a line into the chamber, then a lubricator at the surface seals around the line by allowing the pressure barrier to be released and the submersible pump assembly to be lowered into the well to a desired depth. Preferably, there is a lower pressure barrier in the well. The upper pressure barrier may be a packer that may be collapsed and retrieved alongside the submersible pump assembly. The pressure barrier also may be a packer that is temporarily set in the well, then engaged by the submersible pump assembly, with the pump assembly and packer then being lowered as a unit to a further depth in the well.

Title: Assessing lipid metabolism
Inventor: BARENDSE WILLIAM JOHN
IPC: C12Q1/6876
Filed: 1998-10-23
Granted: 2009-07-21
Abstract: This invention relates to methods and nucleic acid probes for assessing characteristics of lipid metabolism in animals, and in particular to methods of predicting fat levels in meat, milk, or other fat depots of animals. Thus the invention provides a method of assessing the fat metabolism characteristics of an animal, comprising the step of testing the animal for the presence or absence of one or more markers selected from the group consisting of: a) an allele of the 5' untranslated region of the gene encoding thyroglobulin; b) an allele of the DNA polymorphism CSSM34, associated with the gene encoding retinoic acid receptor gamma (RARG); c) an allele of the DNA polymorphism ETH10, associated with 11-cis, 9-cis retinol dehydrogenase (RDH5). The invention is particularly applicable to predicting deposition of fat in muscular tissue, which produces the characteristic "marbling" of meat, and to assessment of milk fat content. The methods of the invention are useful in selection of animals, particularly cattle, for ability to produce or high levels of marbling in meat, and to produce high or low levels of milk fat content.

Abstract: A showerhead includes a housing and a face plate to confine a chamber therebetween. A plurality of spray nipples are mounted on the face plate. Each spray nipple includes a nozzle body and a securing sleeve member. The nozzle body is made of a deformable material, and includes a stem portion with a shank end fitted to a respective inner peripheral wall in the face plate, a tapered end extending outwardly of a front major wall of the face plate, and a shoulder portion formed at a juncture of the shank and tapered ends. An enlarged head portion is secured to the shank end opposite to the tapered end, and defines an abutment shoulder to abut against a rear major wall of the face plate. A spray passageway extends from the stem portion through the enlarged head portion. Thus, the tapered end is bendable relative to the front major wall such that particulate dirt will be bounced out of the spray passageway once the tapered end swings back to its original state.      The securing sleeve member is sleeved on the shank end, and abuts against the shoulder portion and the front major wall to cooperate with the abutment shoulder to clamp the face plate therebetween so as to secure the respective spray nipple to the face plate.

Abstract: A finishing section of a recessed wall wash light fixture has a heat conducting side wall. The inner surface of the side wall has a reflective finish. A lamp is non-centrally aligned within the finishing section. The reflective sides cooperate with the off axis location of the lamp to operate as a kick reflector to kick a portion of the light emitted outward from the fixture at high angles to illuminate a nearby wall close to the ceiling line. The finishing section functions as a lamp support, heat shield and kick reflector reducing the number of parts and complexity of assembly typical of wall wash light fixtures. The finishing section is mounted substantially within a rough-in section housing. An aperture cone section, lens, hinge and bias mechanism, and rotatable collar improve performance and functionality of the fixture.

Granted: 2009-09-08
Abstract: A fluidized catalytic cracking system (10) includes a riser (16) for contacting catalyst and hydrocarbon feedstock. The riser (16) has an inner surface that defines a central passage (17). The central passage (17) acts as a flow path for the catalyst and the hydrocarbon feedstock. A plurality of ribs (29) are disposed on the riser inner surface. The ribs (29) increase the degree of mixing that occurs between the catalyst and the hydrocarbon feedstock within the central passage (17). In particular, each rib (29) has a contoured inner wall (29a). The contour of the inner wall (29a) forces a portion of the catalyst flow inward, toward the hydrocarbon-rich center of the central passage (17).
