Patent EP-0473775-A4 (EP)
Title: Methods for reducing lost motion and wire distortion in spring clutches
IPC: F16D13/08
Filed: 1991-02-20
Abstract: A spring clutch for limiting lost motion during release is provided. The spring clutch includes a shaft (29), a helically wound coaxially mounted spring (31) for making frictional contact with the shaft (29), and means (33), such as a tang element, for selectively applying a loosing force to at least one end of the spring (33) for rotation thereof with respect to the shaft (29). The inventive spring clutch further includes means (39) for urging the spring (31) toward the shaft (29) when the spring (31) is rotatably loosened. As a result, radial movement of the spring (31) away from the shaft (29) is substantially prevented. The urging means (39) may be retained by a housing (35) coaxially mounted about the shaft (29) and may be chosen from a boss (27) or an auxiliary spring (39). Preferably, the urging means is located at about 90 degress along the outer radial surface of the shaft from the end of the spring at which the tang element (33) is located. In another embodiment, a core is coaxially mounted within the shaft such that the spring is located between the shaft and the core and the urging means is retained by the core.

Patent EP-0746774-A4 (EP)
Title: Detection of explosive and narcotics by low power large sample volume nuclear quadrupole resonance (nqr)
Inventor: BUESS MICHAEL L
IPC: G01N24/00
Filed: 1992-04-24
Abstract: The sensitive detection of explosives and narcotics by nuclear quadrupole resonance (NQR) is performed at low rf power by assuring that the rf field strength is larger than the local magnetic field. Additionally, it has been recognized that signal-to-noise ratio of a signal induced by a specimen of fixed size decreases by only the square root of the coil size. Thus, rather than scaling power linearly with coil size, as conventionally done to maintain the same rf field intensity, the power needs only be increased by the square root of the increased coil size to assure maintenance of the same signal to noise ratio. This technique permits the use of larger coils than previously used. The invention is useful for both volume coils and surface coils.

Title: Membrane-associated immunogens of mycobacteria.
Inventor: KAPOOR ARCHANA
IPC: A61K39/00
Filed: 1993-06-28
Abstract: Nucleic acid encoding four novel immunodeterminant protein antigens of M. bovis BCG, which is a vaccine strain for tuberculosis, have been isolated. These genes were isolated as immunoreactive recombinant clones from a genomic library of M. bovis BCG DNA and screened with sera collected from tuberculosis patients. The BCG DNA expressed an antigen of Mr 90 kD, and an ORF encoding 761 amino acids encoding a protein of deduced molecular weight 79 kD, was indentified to encode a membrane bound, ion-motive ATPase of M. bovis BCG. The approach described here can be used to identify immunogens of mycobacteria. The well-characterized M. bovis BCG antigens can be used in the prevention, diagnosis and treatment of tuberculosis. The 79 kD antigen is also useful in the design of recombinant vaccines against different pathogens. The sequence of the 79 kD membrane-associated polypeptides also are useful for the development of specific PCR amplification based diagnostic procedures for the detection of mycobacteria. The promoter of the 79 kD antigen is useful for expressing homologous and/or heterologous antigens in mycobacteria.

Title: Improvements in protein separation
Inventor: MARGOLIS JOEL
IPC: G01N27/447
Filed: 1994-04-07
Abstract: A method and apparatus for preparative electrophoresis useful in large scale recovery of macromolecules such as proteins. An electrophoretic potential with an initial polarity is applied across an electrophoretic medium (13) so as to induce at least two species of macromolecules (1, 2) in a mixture (3) with a first electrolyte solution to move into the medium (13) and towards a second electrolyte solution on an opposite side of the medium (13). The at least two species of macromolecules (1, 2) have similar transport characteristics, although at least one (1) of the at least two species of macromolecules (1, 2) move(s) through the medium (13) at a faster rate than the other species of macromolecules (2). The initial polarity is maintained until just before any of the other species of macromolecules (2) have emerged into the second electrolyte solution whereupon the polarity of the electrophoretic potential is reversed while preventing the proportion of the at least one species of macromolecules (1) which has already emerged into the second electrolyte solution from being drawn back into the medium (13). The application and reversal of the electrophoretic potential is repeated until a desired proportion of the at least one species of macromolecules (1) has been transferred to the second electrolyte solution. Preferably, the ratio of times of the initial polarity to the reversed polarity is between 1:2 and 1:4 so that the other species of macromolecules (2) are substantially completely driven back into the first electrolyte solution.

Title: Composition and method for enrichment of white blood cells from whole human blood
Inventor: KASS LAWRENCE
IPC: A61K35/18
Filed: 1994-04-14
Abstract: A composition and method for separating red blood cells from whole blood comprising a rouleaux-forming aggregator and an enhancer for enhancing the settling rate. The enhancer is a material which alters directly or indirectly the properties of the red blood cell and may alter the structure and/or reactivity of the aggregator, without adversely affecting the morphology and function of white blood cells. In most instances, the red blood cell enhancers of the invention are osmotic agents. Such agents create a hypertonic solution while not entering the cells themselves. Preferably the enhancer is a salt of oxalic acid, a salt of malonic acid, mannitol or sucrose. Potassium oxalate is most preferred. High molecular weight substances which are large enough to form molecular bridges between red blood cells from the aggregators used in the invention. Examples of useful aggregators include dextran, hespan, pentaspan, ficoll, gum arabic, polyvinylpyrrolidone, nucleic acids, and proteins such as fibrinogen and gamma globulins.
