Abstract: An improved centrifuge having a clutch mechanism (120) with a shifting coupling (122) which provides a positive lock for synchronous blade (170) and bowl (185) rotation during processing. The scraper blades (310, 320, 330, 340) have recesses (314, 324, 334, 344) for inserts (315, 316, 325, 326, 335, 336, 345, 346) permitting a variable cutting edge geometry and the mixing and matching of cutting edge geometry while using the same base blade (300). The centrifuge has a tangential outlet (507) and an annular housing (502) to minimize spray and misting in the exiting centrifuged liquid. The centrifuge has a plurality of blades (610, 620, 630, 640, 710, 720) with radially overlapping edges (614, 624, 534, 644, 714, 724) to keep the fluid being centrifuged compartmentalized and thus quiet for maximum efficiency. The scraping assembly blades (610, 620, 630, 640) are angled (617, 627, 637, 647) in the scraping direction to force the solids towards the exit of the centrifuge. A programmable logic controller monitors the load on the drive motor (207) to determine flow rate of injected fluid and/or to ascertain whether any dysfunction is occurring and to take appropriate steps to correct malfunction.

Title: Conjugated polymer tag complexes
Inventor: LEIF ROBERT C
IPC: G01N33/532
Filed: 2000-10-07
Granted: 2011-08-02
Abstract: Processes are described for: (1) the sequential solid phase synthesis of polymers with at least one tag, which can be a light emitting and/or absorbing molecular species (optical-label), a paramagnetic or radioactive label, or a tag that permits the physical separation of particles including cells. When multiple optical-labels are suitably arranged in three-dimensional space, the energy transfer from one moleculars species to another can be maximized and the radiationless loss between members of the same molecular species can be minimized; (2) the coupling of these polymers to biologically active and/or biologically compatible molecules through peripheral pendant substituents having at least one reactive site; and (3) the specific cleavage of the coupled polymer from a solid phase support. The tagged-peptide or polymers produced by these processes and their conjugates with an analyte-binding species, such as a monoclonal antibody or a polynucleotide probe are described. When functionalized europium macrocyclic complexes, as taught in our U.S. patents 5,373,093 and 5,696,240, are bound to polylysine and other peptides, the emitted light increases linearly with the amount of bound macrocyclic complex. Similar linearity will also result for multiple luminescent macrocyclic complexes of other lanthanide ions, such as samarium, terbium, and dysprosium, when they are bound to a polymer or molecule.

Title: Temperature insensitive fiber-optic torque and strain sensor
Inventor: JESSOP PAUL E
IPC: G01L1/24
Filed: 2002-11-27
Granted: 2010-01-05
Abstract: The present invention provides a simple design for a temperature-insensitive extrinsic polarimetric strain sensor. The sensing element is a thin sheet of photoelastic material that is bonded to the test object. It is illuminated with linearly polarized light with the polarization direction at 45 degrees relative to the strain-induced fast and slow axes in the photoelastic material. The sensor measures the difference between the strains along these two orthogonal directions. The reduced sensitivity of the sensor to temperature results from the fact that the illumination is perpendicular to the surface of the test object. All polarization components that are parallel to the surface will experience identical refractive index changes due to thermal effects. Consequently, a measurement of the difference in strains along two directions in the surface plane is insensitive to temperature.
