Abstract: L'invention concerne un procédé permettant de propager des progéniteurs mammaliens d'origine endodermique, tels que les progéniteurs hépatiques, leur descendance, ou des mélanges de ceux-ci sur une couche de cellules nourricières embryonnaires mammaliennes dans un milieu de culture. Le milieu de culture peut être complété par une ou plusieurs hormones et par d'autres agents de croissance. Ces hormones et autres agents de croissance peuvent comprendre l'insuline, la dexaméthasone, la transferrine, la nicotinamide, la sérumalbumine, le .beta.-mercaptoéthanol, l'acide gras libre, la glutamine, le CuSO¿4? et le H¿2?SeO¿3?. le milieu de culture peut également comprendre des anticorps. Le milieu de culture ne comprend pas de sérum. Le procédé décrit dans cette invention comprend des moyens permettant d'inciter la différentiation des progéniteurs de leurs formes adultes, telle que la différentiation des cellules souches hépatiques des hépatocytes ou des cellules biliaires, par ajout ou par exclusion du facteur de croissance épidermique, respectivement. Le procédé de production de progéniteurs mammaliens est utile en ce que les progéniteurs peuvent être utilisés ultérieurement dans un ou plusieurs des procédés suivants: l'identification des facteurs de croissance et de différentiation, les études toxicologiques, la mise au point de médicaments, les études antimicrobiennes, ou la préparation d'un organe extra-corporel, tel qu'un foie bioartificiel.

Abstract: A downhole pump assembly is suspended by tubing in a well. The pump assembly has a separator attached below a progressing cavity pump with a flexible shaft to accommodate the concentric path of the shaft of the separator and the eccentric path of the rotor of the pump. Vanes on the shaft of the separator use centrifugal force to separate the heavier liquids from the lighter gases in the well fluids. The separator discharges the gas into the casing and the liquid to the pump. A motor drives both the separator and the pump. A gear reduction unit is located between the motor and the pump in order to reduce the rotational speed from the motor to the desired rotational speed of the rotor for the pump.

Abstract: Each time a predetermined type of note controlling performance data (e.g., note-on event data) is detected from among a series of performance data, deviation values for a plurality of channels, varying in deviation state among the channels, are set such that a control value of a predetermined tone characteristic (e.g., event generation timing), included in the note controlling performance data, is caused to vary among the plurality of channels. Then, values, obtained by causing the control value vary among the plurality of channels in accordance with the respective deviation values of the channels, are set as new control values for the corresponding channels. Then, for each of the channels, there is created note controlling performance data of the predetermined type having the corresponding new control value incorporated therein. In this manner, there can be generated performance data of a plurality of channels which have respective control values subtly varying among the channels, and these performance data can be used for an ensemble performance. As a modification, a break of a phrase in a series of performance data may be detected so that control can be performed to allow a control value of a predetermined tone characteristic to vary among a plurality of channels per phrase.

Abstract: This invention is a method and apparatus for making a pressure-containing threaded tubular connection, suitable for remotely operated connection and separation, utilizing electrical heating to reduce the amount of makeup torque required to produce reliable preloading of the connection. One aspect of the present invention comprises: a) a first hub with male threads on its exterior and having a sealing face and axial flow passage, b) a second hub having an axial flow passage and carrying an annular seal which can be mated with the sealing face of the first hub and mounting a rotatable nut having female threads on its interior and integral nut heating means. After stabbing and initial make-up of the connection, the nut is heated and thereby expanded in a controlled manner and the connection retightened. Following cooling, the structural connection is fully preloaded and the annular seal fully compressed so that it seals. Reversing the procedure permits disconnection.

Abstract: The sulfur content of liquid cracking products, especially the cracked gasoline, is reduced in a catalytic cracking process employing a cracking catalyst containing a high content of vanadium. The cracking process involves introducing at least one vanadium compound into a hydrocarbon-sulfur containing feedstock to be charged to a fluid catalytic cracking reactor operating under steady state conditions and containing an equilibrium fluid craking catalyst inventory within the reactor. The amount of sulfur in the liquid products, in particular gasoline and LCO fractions, is reduced as a result of the increased vanadium content on the equilibrium catalyst. Advantageously, sulfur reduction is achieved even in the presence of other metal contaminants, such as nickel and iron, on the equilibrium catalyst.
