Title: Binding molecules derived from immunoglobulins which do not trigger complement mediated lysis
Inventor: ARMOUR KATHRYN LESLEY
IPC: A61P37/00
Filed: 1999-05-07
Granted: 2010-10-26
Abstract: Disclosed are binding molecules which are recombinant polypeptides comprising:  (i) a binding domain capable of binding a target molecule, and (ii) an effector domain having an amino acid sequence substantially homologous to all or part of a constant domain of a human immunoglobulin heavy chain; characterised in that the binding molecule is capable of binding the target molecule without triggering significant complement dependent lysis, or cell mediated destruction of the target, and more preferably wherein the effector domain is capable of specifically binding FcRn and/or Fc.gamma.RIIb. These are generally based on chimeric domains which are derived from two or more human immunoglobulin heavy chain CH2 domains. In preferred embodiments the regions 233-236, and 327-331, are modified, as are further residues to render the molecule null allotypic. The binding domain may derive from any source appropriate to the (usually clinical) application for the molecule and may be from e.g. an antibody; an enzyme; a hormone; a receptor; a cytokine or an antigen; a ligand and an adhesion molecule. Also disclosed are nucleic acids, host cells, production processes and materials, and uses e.g. to inhibit B cell activation; mast cell degranulation; phagocytosis, or to inhibit the binding of a second binding molecule to the target molecule.  Pharmaceutical preparations are also disclosed.

Abstract: A pump has a rotor with two or more flexible vanes forming one or more compartments between adjacent vanes. The rotor is mounted offset relative to a rotor sleeve such that the volume of the compartments varies as the rotor rotates in the sleeve.      Incoming fluid is supplied to the compartments along a plane perpendicular to the plane of rotation of the vanes. Fluid is discharged from the compartments through discharge slots in the sleeve leading into a discharge outlet which is tangential relative to the plane of rotation of the vanes. Each flexible vane is formed from at least two thin leaf springs separated by a layer of laminate and joined to a shoe which engages the inner surface of the sleeve as the rotor rotates. The pump in accordance with the present invention is energy efficient and uses significantly less power than comparable known devices.

Title: Method and apparatus for locating gps equipped wireless devices operating in analog mode
Inventor: SOLIMAN SAMIR S
IPC: G01S5/00

Granted: 2009-07-14
Abstract: An apparatus and method for locating a remote station operating in analog mode, and that may not have a sense of network time, using an inverted GPS approach. The invention also enables remote stations operating in analog mode that do not know true GPS time to determine their own location. A time stamp, reflecting the approximate time a satellite range measurement is made, is assigned to the measurement at either the remote station or elsewhere in the network. The difference between true GPS network time and the measurement time is treated as a variable "error" in measurement, the length of which is unknown. This variable error is determined and used in determining the physical location of the remote station.

In the fabric weave pattern, each member of each triplet set of warp yarns interweaves with the paper side weft yarns to occupy in sequence segments of an unroken warp path in the paper side surface, and the members of each triplet interlace in pairs with single machine side layer weft yarns.  Each segment in the unbroken warp path is separated by at least one paper side layer weft yarn. The machine side layer interlacing points can be regularly or irregularly spaced. After heat setting, the fabrics typically have a warp fill from boutt 105 % to about 140 %, an open area of at least 35 % in the paper side surface, and an air permeability typically from about 3,500 to about 8,200 m3/m2/hr.

Abstract: A stainless steel sheet useful as a separator for a low-temperature fuel cell has the surface state that a lot of fine projections (p) stand clo se together around many fine pits (d) formed over a whole surface. The surface state is realized by alternating electrolytic etching in a ferric chloride solution. When the stainless steel separator is built in a fuel cell, contac t resistance between the separator and a graphite electrode is kept at a lower level even in a corrosive atmosphere. Consequently, the fuel cell can be driven with high power-generating efficiency over a long term even under severely corrosive conditions without generation of massive Joule heat.

Abstract: In a moving picture, pixel values are a function of both space and time. A  measure of visual significance is generated by taking the pixel along with a second, nearby, randomly chosen pixel (though its temporal offset from the first may be fixed) and comparing these with a comparison pixel pair. The comparison pair are randomly selected from the image (though its temporal offset may be fixed) but the spacial and temporal displacement between the members of the comparison pair is the same as between the numbers of the test pair. Further comparison pairs are then chosen, and the measure generated depends on the number of matches obtained in the comparisons. A third pair may also added. Also, the pairs may be replaced by groups of more than two.
