Abstract: A gas burner mounting assembly includes a gas injector having a main body portion positioned between a chassis member of a gas cooking appliance and a ceramic based cooktop of the appliance. The gas injector also includes an upper body portion which extends through an aperture formed in the cooktop. A burner retention bracket is interposed between the main body portion of the gas injector and an underside of the cooktop. A resilient support preferably acts between the gas injector and the cooktop, although no rigid attachment is made between these elements. The gas injector is mechanicaly, fixedly secured to the cooktop in order to allow the gas injector to flex with the cooktop.

Title: Procede pour purifier des solutions de silicate de metal alcalin
Inventor: DADE-FIGUEROA TANYA
IPC: C01B33/20

Granted: 2004-07-13
Abstract: L'invention concerne un procédé pour purifier des solutions commerciales de silicate de métal alcalin. Le procédé consiste à faire passer la solution de silicate de métal alcalin à travers un dispositif de nanofiltration qui comprend une membrane présentant un seuil de rétention des molécules compris entre environ 400 et 3000 daltons. De préférence, le seuil de rétention des molécules se situe entre environ 400 et 1000 daltons ou, mieux encore, entre environ 400 et 800 daltons. On peut ainsi éliminer une grande partie des impuretés présentes dans les solutions de silicate de métal alcalin et tendant à se mélanger avec des silicates de poids moléculaire supérieur. Une pression différentielle peut être mise en oeuvre pour faire passer la solution à travers le dispositif, duquel on retire un perméat sous forme de solution purifiée de silicate de métal alcalin. Le retentat resté dans le dispositif est, de préférence, recyclé vers la solution de silicate de métal alcalin d'alimentation pour former un mélange, lequel est placé dans le dispositif de nanofiltration. Deux ou plusieurs dispositifs ayant un seuil de rétention des molécules décroissant peuvent être utilisés en série pour obtenir une forme plus concentrée d'une solution de silicate purifiée. Lorsque deux dispositifs sont utilisés, le deuxième dispositif présente un seuil de rétention des molécules suffisant pour permettre aux molécules d'eau de passer mais en retenant la plupart des molécules résiduelles. Ce résultat peut être atteint avec un seuil de rétention des molécules d'environ 100 à 600 daltons ou, de préférence, d'environ 150 à 400 daltons.

Title: Methods and apparatus for exchanging data
Inventor: GRIMES JAMES E
IPC: H04J3/06

Granted: 2012-06-19
Abstract: The present invention is a communication unit (18) for exchanging data. More specifically, the unit (18) includes an initiator (20) and a responder (24) that exchange data with a single time base. In one embodiment, the initiator (20) generates a time base output signal that is used for determining a multiple of the rate at which data will be transferred to the responder (24).  When data is received from the responder (24), the time base signal is used to over-sample the data to determine the point at which the data from the responder (24) is valid.

Abstract: The present invention is directed to a disposable pull-on garment having a longitudinal center line, a front region, a back region and a crotch region between the front region and the back region. The disposable pull-on garment includes a chassis provided in the front, back and crotch regions. The chassis has edge lines in the front and back regions and includes a liquid pervious topsheet, a liquid impervious backsheet associated with the topsheet, and an absorbent core disposed between the topsheet and the backsheet.      The disposable pull-on garment further includes at least one pair of extensible ear panels extending laterally outward from the chassis in the front or back region. Each of the ear panels has an outermost edge line. In one aspect of the present invention, at least one of the outermost edge lines has a nonuniform lateral distance from the longitudinal center line in the unconcracted state of the garment. The ear panels are joined to the chassis along the corresponding edge lines to form two leg openings and a waist opening. In another aspect of the present invention, each of the ear panels is joined to the chassis along the corresponding edge lines to form a seaming line, thereby forming two leg openings and a waist opening. At least one of the seaming lines has a nonuniform lateral distance from the longitudinal center line in the uncontracted state of the garment.

Patent CA-2342657-C (CA)
Inventor: GRAVES KYLE
IPC: E21B33/16
Filed: 2001-03-30
Granted: 2004-11-02
Abstract: The present invention is a method and apparatus for the completion of wells in which the production tube is run and cemented with only one downhole trip into the well. The completion tool string includes a pressure activated cementing valve, an external casing packer, a pressure activated production valve and a plug landing collar. This tool series is assembled near the end of a production tube string between a well production screen and a well production packer. With the production screen in place, an opening pump-down plug is delivered against the landing collar to seal the internal bore of the tube string below the pressure actuated production valve. Fluid pressure within the tube string is raised to inflate the external casing packer against the borehole wall or casing. Additional pressure increase opens the pressure actuated cementing valve. The desired quantity of cement is pumped down the tubing bore and through the cementing valve into the borehole annulus. Cement flow is forced toward the up-hole direction by the external casing packer which blocks the annulus below the cementing valve. A closing pump-down plug caps the cement volume and is driven down the tubing bore by water or other well working fluid. The closing plug engages a valve closing seat in the cementing valve. Increased fluid pressure behind the closing plug first closes the cementing valve and second, shears the seat retaining pins to drive the closing plug against the fluid column between the two plugs. The resulting fluid pressure increase opens the pressure actuated production valve to purge the residual cement between the plugs and open a well fluid flow path around the plugged landing collar into the production flow tube.

Abstract: In the process of producing corn-based pellets, preconditioner steam and wat er addition, as well as extruder water or screw configuration and RPM, can be manipulated to precisely control the cook level, gelatinization, and moistur e level of the meal during processing, and level of defects despite minor variation in the characteristics of the corn flour. Specifically, the preconditioner added steam-to-water ratio can be manipulated to effect cook, hydration, and partial gelatinization of the meal. In the extruder, lower extruder rotational speeds increase the residence time and increases cook. With the increase in residence time the volume of bed pack in the extruder increases. This can be reversed by adding water directly into the extruder, thereby decreasing the viscosity of the meal in the extruder. Product bulk density is changed by increasing and decreasing cook of the meal.

Granted: 2012-07-17
Abstract: A reagent composition adapted to be coated onto a support surface in order to provide that surface with a high density of reactive groups. The surface, thus coated, can be used for any suitable purpose, and is particularly well suited for use as a solid phase synthesis support surface. The synthesis support surface, in turn, can be used in repetitive and combinatorial syntheses such as the synthesis of polynucleotides, polypeptides and polysaccharides. The polymeric coating can be used to provide increased effective surface area, particularly in situations in which the effective area of the support surface is itself limited, as on the surface of a silicon wafer. In so doing, the polymeric coating provides an optimal combination of such properties as reactive density and surface area or volume.
