Granted: 2001-07-17
Abstract: The present invention consists of a shaft packing with an inner seal (4) and an outer seal (2) which are biased by means of springs (5) and an intermediate ring (1). The spring package and the major part of the shaft packing are positioned on the outside of a wall (20) of a container or the like, on the inside of which container an aggressive medium may be found. On the inside of the wall and in contact with the medium there are only a counter ring (4'), the inner seal (4), the in-termediate ring (1), and a mounting (14). All these parts have smooth surfaces without grooves, notches or the like in order to avoid that the possibly aggressive medium accumulates on the shaft packing. The shaft (19) is journalled in the wall (20) by the mounting (14), and the contact surfaces (22) between the mounting (14) and the wall (20) have circular cross-sections. The mounting (14) is prevented from ro-tating by means of a washer (17) secured to the wall (20) and lowered into a groove (21) on the outer surface of the mounting (14). A flush-ing space as defined between a sleeve (8) fixed on the shaft, the inner sleeve (4'), the inner seal (4), the intermediate ring (1), the outer seal (2) and the outer sleeve (2') for lubrication of the inner and outer seals (2, 4) and their sliding surfaces. The flushing is also intended to re-move particles possibly detached by the rotation of the shaft.

Title: Methods and compositions for the detection of soluble .beta.-amyloid peptide
Inventor: SCHENK DALE B
IPC: C12Q1/68
Filed: 1993-09-10
Granted: 2011-11-01
Abstract: Soluble .beta.-amyloid peptide (.beta.AP) is measured in biological fluids at very low concentrations, typically in the range from 0.1 ng/ml to 10 ng/ml. The measurement of .beta.AP  concentrations in animals or conditioned medium from cultured cells can be used for drug screening, where test compounds are administered to the animals or exposed to the cultured cells and the accumulation of .beta.AP in the animal or culture medium observed. It has been found that elevated levels of .beta.AP in body fluids, such as blood and cerebrospinal fluid, is associated with the presence of a .beta.AP-related condition in a patient, such as Alzheimer's Disease. Methods for diagnosing and monitoring .beta.AP-related conditions comprise measuring the levels of .beta.AP in such body fluids from a patient.

Patent CA-2135939-C (CA)
Inventor: MCGUIRE JOHN DENNIS
IPC: E06B11/08
Filed: 1994-11-16
Granted: 1999-02-02
Abstract: A turnstile is disclosed which is easily adapted to operate in either a clockwise or counterclockwise direction of rotation and which does not permit reverse rotation during operation. Resistance to rotation in the reverse direction is achieved by means of a drag shoe mechanism. As a rotor mechanism rotates about a corresponding stator mechanism it trails a drag shoe by a rigid connecting rod, or drag arm, across a bearing surface. The drag arm is disposed at a non-perpendicular angle. In reverse motion the angularly inclined drag arm forces the drag shoe to jam into the bearing surface and thereby act as a brake. The turnstile is provided with a quick release wrench, an safety release bolt which protrudes beyond the housing of the turnstile mechanism, and emergency release instructions labels clearly visible on the top and pillar of the turnstile. Should a child, or other person,become trapped in the turnstile one may easily and quickly release the turnstileby inserting the wrench in the safety release bolt and loosening the mechanism. When loosened the mechanism, and hence the turnstile, swings freely in either direction.

Title: Crf binding protein
Inventor: POTTER ELLEN
IPC: G01N33/566
Filed: 1993-10-25
Granted: 2002-04-02
Abstract: Corticotropin Releasing Factor-binding protein (CRF-BP) is produced recombinantly and is useful for modulating the bio-logical activity of CRF. CRF-BP or fragments thereof and/or antibodies to the proteins are employed in diagnostic assays to de-termine the levels of CRF, CRF-BP and the ratio of CRF/CRF-BP in a vascular fluid sample. Following such an assay, CRF-BP can be effectively employed to treat pregnancy-related pathological disorders by lowering the ratio of CRF/CRF-BP to within a normal range for pregnancy. The anti-CRF-BP antibodies are also useful to purify the CRF-BP and to modulate the biological effect of CRF-BPs.

Title: Improved process to prepare triorganotin lithium
Inventor: HERGENROTHER WILLIAM L
IPC: C08F4/48
Filed: 1995-05-12
Granted: 2003-07-08
Abstract: Solutions of triorganotin lithium are described having low residual concentrations (preferably less than 2,000 ppm) of halide.  These are produced by a two-step process.          Triorganotin halide is reacted with lithium to produce hexaorgano ditin and a precipitate of lithium halide.   The lithium halide precipitate is removed by filtration and/or use of highly concentrated reaction conditions.  Then the hexaorgano ditin is further reacted with  lithium  to  form  the  triorgano  substituted  tin lithium.   The  lithium halide is  less soluble  in hot tetrahydrofuran (THF) and/or more concentrated solutions. THF is a preferred solvent for the reaction.   The low-temperature reactions described result in low amounts of inactive and/or undesirable byproducts. These triorganotin lithium compounds are useful as anionic initiators that result in polymers with terminal tin compounds,  e.g., triorganotin, attached to the terminal end of the polymer where initiation occurred.  The polymers with terminal tin compounds have lower hysteresis in cured carbon black-filled  elastomeric  compounds.    Low concentrations  of residual halides in the initiators and consequently in the polymers has been associated with reduced amounts of volatile  organotin  compounds  being  generated  during processing of polymers with organotin terminal groups.
