Title: Hollow fiber bundle element for an adsorber
Inventor: PAN CHUEN YONG
IPC: B01D53/04
Filed: 1990-08-10
Granted: 1999-04-27
Abstract: An  adsorber  is  provided  comprising  a bundle  of microporous hollow fibers disposed in a cylindrical impermeable casing.   With respect to each fiber, its wall is selected to provide a permeability in the microfiltration range (0.05 to 5 micrometers).   The bundle forms two longitudinal passageways, being the lumina of the fibers and the other being the void space between the fibers.  A first of these passageways is densely and uniformly packed with minute adsorbent particles.  No binder is used to fix the particles - they maintain their distribution in the passageway as a result of having been densely packed under pressure.  The ends of the first passageway are sealed and the fiber wall pores are smaller than the particles, whereby the adsorbent particles are immobilized therein.  A fluid mixture, comprising a carrier and an adsorbate, is introduced into the second passageway.   The adsorbate diffuses through the fiber walls and is collected by the adsorbent particles.  By way of result,  the particles used in this adsorber can be of much smaller size than those used in a conventional fixed bed column.          The use of small adsorbent particles enhances adsorption rate, and availability of a  separate longitudinal  flow passageway reduces pressure drop across the adsorber.

Abstract: HIGH-SPEED TIME-DIVISION SWITCHING SYSTEM Abstract A non-blocking broadband broadcast time-division switching system (10) comprises a time-slot replication stage (12) followed by a conventional TMS stage (11). The replication stage replaces the TSI stage of conventional switching systems. Time division multiplexed links (16) are connected to inputs of the system. Each input link is connected to the input of a different replicator (14). Each replicator has as many outputs as there are timeslots (202) in a frame (201) on an input link. Replicators' outputs are connected each to a different input of the TMS stage. In one embodiment, a replicator generates each time slot of a received frame at a different output and replicates the individual time slot at the individual output during each time-slot interval of a frame interval. In another embodiment, a replicator generates each time slot of a received frame at a different time at each output, thus generating a delayed replica of the received frame at the outputs. In either embodiment, during each time-slot interval, each replicator transmits a frame of different received time slots to the TMS stage.

Title: Production of nitrogen free of light impurities
Inventor: AGRAWAL RAKESH
IPC: F25J3/08
Filed: 1991-07-30
Granted: 1994-05-17
Abstract: ABSTRACT   This invention relates to a cryogenic process for the separation of air utilizing an integrated multi-column distillation system wherein an ultra high purity nitrogen rich, oxygen rich and optionally an argon rich product are generated.  In the cryogenic distillation separation of air, air is initially compressed, pretreated and cooled for separation into its components.  Ultra high purity, e.g., nitrogen having less than 0.1 ppm of volatile impurities is generated with enhanced nitrogen product recovery by withdrawing liquid nitrogen from the higher pressure column at an intermediate point and charging that fraction as reflux to the lower pressure column, withdrawing a nitrogen stream which is rich in volatile contaminants from the top of the high pressure column, partially condensing the nitrogen stream and removing the uncondensed portion as a purge stream, and, withdrawing an ultra high purity nitrogen product at a point below a nitrogen vapor withdrawal point at the top of the lower pressure column.  Alternatively, no purge need be taken and the volatile impurities allowed to pass to the low pressure column.  In that case, a nitrogen fraction rich in volatile impurities is removed from an upper portion of the low pressure column, condensed and at least a portion of the uncondensed fraction removed as a purge and the condensed portion returned to the low pressure column.

Abstract: A  3D  scientific  visualization  system  for viewing models composed of polyhedra or other elements having vertices at which analysis results (e.g., temperature or pressure) are defined.  The model is viewed either in a cutting plane or as a contour surface in which a given result assumes a specified value.  Polygons making up an intersection surface formed by the intersection of the cutting  plane  or  contour  surface  with  the  polyhedra forming the model are generated and passed to a polygon processor  for  rendering  and display  on  a  raster-scan device.  A series of intersection surfaces are generated for display by varying either the position of the cutting plane  along  its normal  or the value  that the  result assumes on the contour surface.  The testing of elements for possible intersection by the cutting plane or contour surface is speeded up by presorting the elements into zones, based upon either  the position of each element along the cutting plane normal or the value of the result over  the  vertices  of  the  element,  and  testing  only elements within certain zones for intersection with the plane or surface.   Intersection calculations for edges shared by multiple elements are minimized by maintaining a global list of edges and flagging those edges whose intersection point with the  cutting plane  or  contour surface has been calculated for any element of the model.          The  outer  surfaces  are  identified  for  viewing  in  an alternative mode of operation by counting the elements sharing a given face of the model and flagging as outer faces those faces associated with only a single element.
