Abstract: A method for assaying for the presence of analyze in a sample based on differential binding affinity involves detecting dissociation of a complex of receptor and ligand in the presence of analyte, The receptor binds the analyte with high affinity and with the ligand with low affinity. The receptor-ligand complex may be formed in situ or may be preformed. In the presence of free analyte, the receptor releases from the receptor-ligand complex and binds free analyte. Release of the receptor-ligand complex is detectable. A kit for performing release assays to detect the presence of analyte is also provided.

Abstract: A sling-type combination child carrying and seat harness apparatus comprises a piece of suitable fabric having at opposite first and second ends thereof a pair of rings and a pair of elongated ties, the latter being adapted to be threaded through the rings and secured thereto to form a loop which is required in a child carrying position of the apparatus. The fabric defines a pouch between the first and second ends for receiving the child in the child carrying position of the apparatus which has been suspended from an adult's shoulder. The apparatus comprises a pocket defined at the first end adjacent the rings in order that the apparatus may be used as a seat harness for a chair or the like having a seat and a back rest. In this case, the apparatus and, more particularly, the pouch is laid partly on the seat of the chair and the pocket is slidably engaged over the back rest. The child is then seated and the fabric intermediate the child and the ties is twisted and brought up diaper-like between the child's legs. The ties are pulled apart and the fabric slack is rolled up, sausage-style, until gathered closely against the front of the child's body. The ties are then brought around the sides of the child and of the back rest of the chair before being secured to the rings behind the back rest.

Abstract: A film of linear organosilsesquioxane polymer, or "ladder" organosiloxane, coated upon the surface of an LiMn2O4 secondary battery electrode (19) and cured to a glassy layer is subjected to plasma oxidation to remove pendant organic groups comprising the coated polymer. The resulting ultrathin silica separator layer (17) is replete with minute pores which take up and retain by capillarity a typical LiCIO4 electrolyte solution. A counter-electrode (15) placed in intimate contact with the silica electrolyte element completes a secondary battery structure (10) in which lithium ions readily migrate through the electrolyte during repeated discharge/charge cycles without loss of element integrity or efficacy.

Title: Improved method for the refolding of proteins
Inventor: THOGERSEN HANS CHRISTIAN
IPC: C07K14/74
Filed: 1994-02-04
Granted: 2001-06-05
Abstract: A novel, generally applicable method for producing correctly folded proteins from a mixture of misfolded proteins, e.g. bacterial inclusion-body aggregates.  A major new aspect of the method is that over-all efficiency is achieved by subjecting proteins to a time-sequence of multiple denaturation-renaturation  cycles, resulting in gradual accumulation of the correctly folded protein. The method has proven efficient for a variety of recombinant proteins.  Also provided are novel encrypted recognition sites for bovine coagulation factor Xa. The encrypted recognition sites described may be activated in vitro by controlled oxidation or by reversible derivatization of cysteine residues and thereby generate new cleavage sites for factor Xa. Two new recombinant serine protease exhibiting narrow substrate specificity for factor Xa recognition sites are also provided.  They may replace natural coagulation factor Xa for cleavage of chimeric proteins.

Abstract: A spool for receiving a fiber optic sensor coil includes a single, substantially-planar mounting flange and a central hub.  The coil can be directly wound upon the hub.  The coil is mounted transverse to the plane of the mounting flange and is unconfined in that direction as the surface of the hub is substantially non-adhesive with respect to the inner layer of the coil. This allows axial coil expansion with increases in temperature without generating gyro bias errors.  The device is also substantially free from vibration-induced bias errors due to the relatively high resonant frequency (vis a vis environmental vibration) of the integral spool-plus-coil structure.

Abstract: Casting device for a metal strip (9) where the solidification is effected by passing the molten metal between two counter rotating rolls (1,1') on horizontal axes. The rolls (1,1') are cooled by the internal circulation of a cooling fluid and the roll gap defines the casting space (2) for the molten metal. The outer surfaces (3,3') of the rolls have a specified roughness. The casting space (2) is rendered inert by blowing a given quantity of a gas or gas mixture across a cover (10) covering the casting space (2). The camber of the rolls (1,1') is regulated by changing the quantity of injected gas and/or the nature of the gas or the composition of the gas mixture, at least around the surface of each roll upstream of the contact zone with the molten metal. Also claimed is device (14,15,16) for blowing the gas and a system (7,18,19,20,21,22,22',23,23',24,24') for modulating the quantity of gas injected and/or the nature of the gas or the composition of the gas mixture. The gas mixture used may be a mixture of nitrogen and argon.

Title: Polyoxyalkylene polyether monool polyurethane foam additive
Inventor: PATTERSON JIMMY L
IPC: C08G18/48
Filed: 1996-04-16
Granted: 2008-11-25
Abstract: There is now provided a polyol composition containing a polyol having polyester linkages, an aliphatic or cycloaliphatic C4-C7 hydrocarbon blowing agent, and a polyoxyalkylene polyether monool initiated with a C8-C24 fatty hydrocarbon having one alkylene oxide active hydrogen atom. We have found that the monool emulsifies the C4-C7 blowing agent in the compound having polyester linkages, to form an emulsified polyol composition, after which an organic aromatic isocyanate may be reacted with the emulsified polyol composition to form a closed cell polyurethane foam. The polyol composition is used to make rigid closed cell polyisocyanate based foams which are dimensionally stable, and have good insulation values and flame retardance. Combining the monool with the polyester based polyol produces a foam having a density lower than that of a reference foam made with the same ingredients and amounts except in the absence of the monool. Whether the monool is merely mixed with the polyol or used to form an emulsion with the hydrocarbon blowing agent and the polyol, the foam density may be lowered when the monool is used.

Title: Sensor system having detector to detector responsivity correction for pushbroom sensor
Inventor: RUSSELL EDGAR E
IPC: H04N5/365
Filed: 1996-05-07
Granted: 1999-08-03
Abstract: A responsivity calibration system for use with an array of detectors. The invention includes a first mechanism for changing the orientation of the detector array from the first orientation, during an operational mode, to a second orientation, during a calibration mode, in which each detector sequentially samples the same portion of the same scene. The inventive system adjusts the output generated by each of the detectors in the first orientation in response to an associated signal generated by that respective detector in the second orientation. In a specific implementation, a normalization factor is generated based on the output of each detector during said calibration mode. The normalization factor is stored and multiplied by the outputs of the detectors during the operational mode. Hence responsivity correction is implemented without the need for either a wide area scene of extreme uniformity or an on-board target.
