    Abstract: A single-state apparatus for injection molding structural foam articles has a resin plasticating barrel in which a cylindrical plunger reciprocates and rotates. The plunger has a screw section for plasticating resin and advancing the plasticate into a metering section with grooves in which plasticate flows. The grooves are contiguous to a fluid foaming agent inlet in the side of the barrel so that they alternately open and close the inlet to introduce fluid foaming agent periodically into the plasticate. Downstream, the plunger has channels for mixing and advancing plasticate to the forward end of the plunger where it accumulates and is periodically rammed by the plunger into the mold.

    Abstract: A system and method for improved cryogenic cooling of process streams in polysilicon manufacturing is provided. The disclosed system and method provides for the cryogenic cooling of a silane and hydrogen process stream during the manufacture of polysilicon with concurrent recovery of refrigeration capacity from the vaporized nitrogen as well as the recovery of refrigeration capacity from the cold hydrogen stream. The improved cryogenic cooling system and method reduces the overall consumption of liquid nitrogen without sacrificing cooling performance of the cryogenic cooling of the silane and hydrogen process stream.

    Abstract: Biological liquid substances in a disposable bioreactor or a disposable fermentor is enriched with a dissolved gas such as oxygen. The gas is provided to the liquid in meeting growth needs of biomass within the disposable vessel. The liquid is processed through a bubble forming element such as a supersonic mixer, a membrane sparger, or the like, to form a gas-liquid dispersion. The dispersion has a high interfacial surface area for facilitating gas dissolution in the liquid. Receptacles of the disposable vessel may be coupled (e.g., magnetically) to one or more processing devices (e.g., motors, pumps, gas sources) outside of the disposable vessel so that components within the disposable vessel are able to perform functions suitable for furthering reaction and/or fermentation processes.

    Abstract: Oxygen is delivered into a liquid contained within a vessel. Oxygen-rich gas is introduced at an inner mixing region of a vessel toward an agitating element for dissolving some of the oxygen into the liquid. Air is introduced to the liquid at a location different from where the oxygen-rich gas is introduced, minimizing coalescing of bubbles of the oxygen-rich gas and air bubbles. Running the agitating element in the vessel may induce mixing of the liquid and improve oxygen dissolution. Movement of the air bubbles can also generate a mixing effect on the liquid, yet independent from mixing caused by the agitating element. In some embodiments, currents produced by the agitating element are asymmetric with respect to a vertical axis of the vessel. Air bubbles may also form an asymmetric configuration of bubbles about the vertical axis.
