  • Patent number: 11365382
    Abstract: The present invention relates to bioreactor system and method thereof wherein support matrix (2) comprises at last one central shaft and plurality of peripheral shaft being radially surrounds central shaft. Arrays of discs (11) are mounted along the shaft by defining interspatial vicinities between two successive plates. Thus, discs mounted on peripheral shafts are rotated within the interspatial vicinity of discs of central shaft to ensures sufficient mixing and avoid stagnant fluidic zones which is created when discs are mounted closely apart from each other on shafts. Further, plurality of deflector vanes that are axially provided along the length of the central shaft to redirect substantially co-axial direction fluid flow into interior of culture vessel and more specifically towards the central axis.

  • Publication number: 20040103180
    Abstract: Signals to a management module are generated on an occurrence of an event affecting one of a plurality of server blades housed in a common chassis with the management module and aggregated in the management module. Signaling in accordance with this invention may be originated at a number of levels of operation of information handling systems, and distinction can be drawn between an occurrence requiring prompt attention from an operator—an alert—and occurrences where such prompt action is unnecessary. Occurrences signaled are logged for possible later review, and such a log will, in the contemplation of this invention, contain events related to a number of server blades.

  • Publication number: 20030023484
    Abstract: An electrode and getter structure for a ring laser gyroscope that includes a frame having a cavity therein that contains a gain medium and an electrode bore extending from a surface of the frame to the cavity includes a metalization layer formed on the surface of the frame. The metalization layer includes an electrode that is adjacent the electrode bore. A getter well is sealed to the metalization layer around the electrode bore, and a getter is mounted in the getter well spaced apart from the frame. The getter well preferably is a hollow glass cylinder having a closed end and an open end mounted to the metalization layer. A spring preferably is retained in the getter well by elastic forces in the spring with the getter being attached to the spring and aligned with the electrode bore.

  • Patent number: 6447653
    Abstract: The present invention provides a method for shaping a mask to reduce coating non-uniformity in the radial direction. A test run of the ion beam sputtering system coats a stationary glass plate having the same area and shape as the platen. The resulting coating thickness is measured across the surface of the glass plate and plotted as a function of position. This is the plot of the flux distribution. The coating rate pattern is determined by coating thickness by coating time. The desired width of the mask, which takes the form of a segment of a radial band is adjusted to obtain the desired average coating rate for the entire segment, masked and unmasked. This is repeated for each radial band. All these radial widths put together design the functional form of the mask, the use of which provides a uniform coating of the platen in a radial direction.
