IPC: B01D53/08
Filed: 2001-12-10
Abstract: A rotary module for implementing a high frequency pressure swing adsorption process includes a stator having a number of function compartments opening unto the stator valve faces, a rotor rotatably coupled to the stator and including a number of apertures opening into the rotor valve faces, and a self-regulating clearance-type valve seat positioned between the valve faces of the stator and rotor so as to regulate the rate of gas flow between the stator and the rotor. Each valve seal includes a sealing face disposed adjacent a respective one of the rotor valve faces and is pivotable relative to the respective rotor valve face for varying the gas flow rate in accordance with the clearance distance between the sealing face and the respective rotor valve face. Each valve seal also includes a passage which communicates with one of the function compartments for varying the clearance distance in response to a pressure differential between the passage and an approaching aperture. In this way, the valve seal maintains a smooth pressure transition profile as the flow paths are switched between the function compartments. As a result, equilibrium is maintained between the adsorbent material and the mass transfer front of the gas, and the efficiency of the gas separation process is enhanced.

Title: Stent for holding passageways open
Inventor: JORDAN ANDREAS
IPC: A61L31/08
Filed: 2000-04-28
Abstract: The invention relates to a stent which can be implanted in passageways or other body cavities, which is made of a metallic and/or non-metallic materia l, and which is evenly coated with nanoscalar particles.

Inventor: HU XIAOPING
IPC: H03M7/40
Filed: 2002-02-11
Abstract: A technique is presented for compressing data which leverages the frequency of an escape symbol for better compression. The prefix of a data string is evaluated and the probability of all characters that might succeed it is predicted in tabular form. Symbols are designated "Hit" or "Miss" based upon whether they are in the table. A binary tree is generated by partitioning nodes into Zero and One groups based on a single bit value. A partition bit is chosen to maximize the difference of probability sums of Hit symbols in Zero and One groups, with exceptions for partitions having non Hit symbols in one of the groups. A  probability value is assigned to each branch, based on the probabilities of Hit and Miss symbols. Encoding a symbol is facilitated by encoding the branch probabilities on the shortest path from the root to the leaf node containing the symbol using arithmetic encoding.
