Title: Bimodal, crosslinked toner resin and process for making same
Inventor: CHUPKA FRANCIS L JR
IPC: C08F291/00
Filed: 1996-05-10
Abstract: A bimodal, crosslinked toner resin can be prepared in non-aqueous solvent, e.g., toluene, using standard solution polymerization techniques. The resin-forming process prepares a precursor resin from ethylenically unsaturated monomer(s), and then grafts malefic anhydride onto the precursor resin to form a modified precursor resin. The modified precursor resin is reacted with a polyfunctional molecule, e.g. a diol, to provide a crosslinked resin. The process is preferably conducted in the presence of a low molecular weight polymeric additive, e.g., polystyrene, to provide a bimodal as well as crosslinked toner resin composition. With the addition of a colorant, a toner powder may be formed.

Patent CA-2243577-A1 (CA)
Inventor: MULKAHY LINDA S
IPC: A61K47/10
Filed: 1997-01-22
Abstract: The extracellular domain of the human erythropoietin receptor (EPO binding protein, EBP) has been expressed and overproduced in E. coli. Control of oxygen levels and pH during high density fermentation allows the production of only the protein variant with the native amino terminus. Methods disclosed permit the efficient recovery of purified EBP which quantitatively binds EPO. The active purified protein competes with membrane associated EPO receptor for binding [125I]EPO  and neutralizes EPO dependent stimulation in a cell based proliferation assay. Further, the radioligand equilibrium binding constant for this interaction has been determined by immobilizing EBP on agarose gel via a free cysteine. The EBP of the present invention has many uses including the structural determination of the protein by NMR or crystallography, in drug design and discovery, and as a therapeutic. A  fusion protein of EBP and an immunoglobulin heavy chain was also produced. This protein, termed EBP-Ig, is a preformed dimerization template and is also useful in drug design and discovery methods.

Patent CA-2252645-A1 (CA)
Inventor: BOVA FRANK J
IPC: A61B5/055
Filed: 1997-04-14
Abstract: Repeat fixation for medical procedures is accomplished using a non-invasive locator, specifically a bite plate (26). The bite plate has at least three fiducial markers on it. The fiducial markers may be LEDs (162), radiopaque markers for angiography, or computerized tomography (CT) imaging, or magnetic resonance markers for magnetic resonance (MR) imaging. By detecting the position of the markers, the position of features within the patient (such as a brain tumor) can be determined with great precision. Since the bite plate (26) has been molded to uniquely fit to the patient's teeth, it may be removed after an initial imaging of the patient. The bite plate (26) may then be reattached one or more times to the teeth. An alternate embodiment uses a head ring (18) or head holder such as a head mask system (276) with the LEDs thereon.

Filed: 1997-09-09
Abstract: The present invention describes the isolation and purification of biologically and immunologically active histidine-tagged Shiga toxins (His-tagged), a toxin associated with HC and the potentially life-threatening sequela HUS transmitted by strains of pathogenic bacteria. The present invention describes how his-tagging greatly simplifies and expedites purifying Shiga toxins, and describes an improved method for such purification. One aspect of the invention is obtaining and using Shiga toxoids that are immunoreactive but not toxic. Another aspect of the invention is obtaining and using fusion proteins of His-tagged Shiga toxins or toxoids. Yet another aspect of the invention is obtaining and using antibodies to His-gagged Shiga toxins, toxoids, or Shiga toxin/toxoid fusion proteins.

Title: Coriolis flowmeters using fibers and anisotropic material to control selected vibrational flowmeter characteristics
Inventor: VAN CLEVE CRAIG BRAINERD
IPC: G01F1/84
Filed: 1997-09-09
Abstract: A Coriolis flowmeter whose flow tubes are made, at least partly, of anisotrophic materials such as fiber reinforced composites. The composite material is formed by orienting the fibers in one direction to increase the tensile strength of the material in that direction. Selected areas of the flow tubes are formed of this composite to increase the flowmeter sensitivity and to separate desired flowmeter vibrational frequencies from undesired vibrational frequencies. Circumferentially oriented fibers increase the internal pressure containment capability of the flow tubes. A strain gauge affixed to the flow tubes flexes with flow tube deformation to indicate the internal flow tube pressure.
