Abstract: L'invention porte sur des particules qui ne sont pas rapidement éliminées du flux sanguin par les macrophages du système réticuloendothélial, et qui peuvent être modifiées pour obtenir des taux de libération variables ou pour viser des cellules ou organes spécifiques. Les particles ont un noyau solide biodégradable contenant de la matière biologiquement active et des fractions de poly(alkylène glycol) sur sa surface. Le groupe hydroxyle terminal du poly(alkylène glycol) permet la liaison covalente des molécules biologiquement actives sur la surface des particules, mais aussi des anticorps ayant pour cible des cellules ou organes spécifiques, ou des molécules affectant la charge, la lipophilie ou l'hydrophilie de la particule. Il est aussi possible de modifier la surface de la particule en fixant des polymères biodégradables de la même structure que ceux qui constituent le coeur des particules. La taille type des particules est comprise entre 1 nm et 1000 nm, généralement entre 1 nm et 100 nm, encore que des microparticules peuvent aussi se constituer selon le processus décrit ci-dessus. Parmi les particules en question peuvent figurer des particules magnétiques ou des matières radiopaques telles que l'air et d'autres gaz, utilisables pour l'imagerie diagnostique, des molécules biologiquement actives à délivrer sur un site, ou des composés ayant ces particules pour cible. Ces particules ont une demi-vie dans le sang prolongée par rapport aux particules ne comportant pas de fractions poly(alkylène glycol) en surface.

Abstract: A packaging container comprises a holding container (11) formed by deforming a multi-layer sheet made of a resin according to a thermoforming method, a lid (13) made of resin and adapted for sealing the holding container (11), and an exterior covering surrounding the exterior of the holding container (11) and made of a non-metallic material having a hardness and a thermal insulating performance higher than those of the holding container (11).  Since no metal is used in the packaging container, the packaging container can be easily crushed after being thrown away, and the collection of the packaging container can be made easier.  Since the holding container (11) and the lid (13) are made of resin and the exterior covering is made of a non-metallic material, food in the packaging container can be directly heated by dielectric heating.  According, the food can be heated to a sufficient temperature within a short time.  Moreover, since the exterior covering has a good thermal insulating performance, the packaging container can be held by hand even immediately after being taken out from a vending machine, and the food held therein is prevented from quickly getting cold.

Abstract: An embryonic stem cell which may be induced to differentiate homogeneously into a desired primary cell line. The embryonic stem cell may be engineered with DNA, which encodes a protein or polypeptide which promotes differentiation of the stem cell into a specific cell line, such as, for example, a neuronal cell line, a muscle cell line, or a hematopoietic cell line. The DNA may encode a transcription factor found in the particular cell line. In another alternative, a desired cell line is produced from embryonic stem cells by culturing embryonic stem cells under conditions which provide for a three-dimensional network of embryonic stem cells, and then stimulating embryonic stem cells with an agent, such as retinoic acid, or dimethylsulfoxide which promotes differentiation of the embryonic stem cells into the desired cell line, such as, for example, a neuronal cell line, or a muscle cell line.

Abstract: A skimmer/coalescer system includes a skimmer which skims a two-component liquid from the surface of a liquid mixture in a tank, and a pump which pumps the skimmed liquid to a coalescer for separating and collecting a lower density liquid component from the mixture and returning the rest of the liquid to the tank.      The skimmer includes a housing submerged below the liquid surface in the tank, an outlet operatively connected to the pump and an intake which supplies liquid to the housing by gravity. The intake includes a vertically movable inlet which remains adjacent the liquid surface regardless of liquid level changes in the tank, thereby to skim near the surface where the lower density liquid dominates, and to enhance skimming efficiency. The skimmer also includes a sensor inside the submerged housing which cooperates with the intake to expand or contract the size of the inlet to increase or decrease in-flow to the housing, respectively, depending on whether the liquid level in the submerged housing is receding or raising. This maintains consistent and continuous liquid flow through the system during operation and minimizes the possibility of pump damage.

Abstract: The present invention defines a convertible elec- trical contact. The convertible contact comprises two pairs of movable contacts attached to an actuator which is supported by and enclosed within a housing. The ac- tuator is biased to a first position and is slidably mov- able to a second position in response to a force applied to the actuator. The movable contacts are attached to the distal ends of a flexible member which is supported at its approximate midpoint by the actuator. The mov- able contacts are also movable between a first position and a second position as the actuator is moved. A pair of contact cavities are defined by the housing such that the one contact cavity lies on each side of the actua- tor and the flexible member and movable contacts are contained within the cavities. The housing defines a first pair of access apertures associated with the first position of the movable contacts and a second pair of access apertures associated with the second position of the movable contacts. A convertible stationary contact module which includes a pair of bussing conductors, each with a stationary contact attached at its end, is employed to complete the electrical contact. By selec- tively placing the bussing conductors and then asso- ciated stationary contacts in either the first or second pair of access apertures, either a normally closed or a normally open electrical contact can be chosen. The contact module is attached to the outside of the hous- ing by a mounting screw.

Abstract: This  invention  pertains  to  rechargeable  zinc  alkaline electrochemical cells.    In cells of the invention,  the anode current collector comprises copper, and from about 0.5% by weight to about 11%  silicon.   Preferred compositions for the anode current collector comprise from about 1% by weight silicon to about  6% by weight  silicon.   Cells  embodying anode  current collectors of the invention exhibit reduced current flow under anode polarization  in alkaline  conditions,  and  reduced cell expansion under abusive electrical drain conditions.  The cells are less susceptible to oxidation of the anode current collector, which is typically irreversible, than known brass anode current collectors.    In  general,  cells  of  the  invention  are  less susceptible to, and generally do not exhibit as much, irreversible chemical reaction activity, as conventional current collectors, especially oxidation of copper at the anode current collector.

Abstract: An  aftercooler  apparatus  condenses  vapor  in untreated  gas discharged from a compressor of a gas drying system.   The apparatus includes a radiator, a bypass line and a bypass valve.          The radiator features a first inlet,  a second inlet and an outlet.  The first inlet connects to the compressor from which it receives the untreated gas.  The outlet connects to the next component in the gas drying system.  The radiator condenses the vapor suspended in the untreated gas and passes aftercooled gas resulting therefrom via its outlet to the next component.  The bypass line, through which the untreated gas may flow, connects at one end between the compressor and the first inlet and at another end to the second inlet.  The bypass valve senses the difference in pressure between the first inlet and the outlet.          The bypass valve also controls the flow of the untreated gas in response to the difference in pressure.  When the difference in pressure is below a preset value,  the bypass valve closes thereby allowing the untreated gas to flow into the first inlet and through the radiator wherefrom the aftercooled gas passes to the  next  component while  carrying  therewith the  condensed moisture for expulsion from the system.  When the difference in pressure reaches or exceeds the preset value, the bypass valve opens thereby diverting the flow of the untreated gas through the bypass line and into the second inlet so as to defrost in the radiator frozen moisture accumulated therein that caused the difference in pressure.

Abstract: A method and apparatus to control the rate at which molten metal is initially fed to a plurality of continuous casting molds (20). Elevation sensors (102, 190) are suspended from beams (68) which in tum are suspended from an elongated rack (56). The sensors generate a signal used to control valve mechanisms (86). During the initial filling phase of the mold (20), the sensors (102, 190) are locked into an initial position in which molten metal is fed to the molds at a specific rate. When the molten metal in the individual molds reaches a specific intermediate level, triggers (66) are activated which allows the elevation sensors (102, 190) to assume control of the rates at which molten metal is fed to the molds. The elevation sensors (102, 190) control the height of the metal columns in the molds at a constant height with respect to the position of the elongated rack (56). After a period of time in which the height of molten metal in the individual molds (20) have established equilibrium, the elongated rack (56) is elevated at a controlled rate to an operating position. In turn, the molten metal in the respective molds is raised to an operating position at a controlled rate.
