Title: Apparatus and method for positioning a sensor away from the blood vessel wall
Inventor: KUJAWSKI DENNIS
IPC: A61B5/145
Filed: 1992-07-08
Abstract: TAH'cp Abstract Apparatus and method for positioning a probe through a catheter wherein a sensing element on the probe is located outside the catheter but is spaced from the luminal surface of the blood vessel to prevent any adverse effect on the sensor measurement.  A standard introducer catheter may be used and a support tube is provided around a portion of the probe and is slidably engagable within the catheter lumen for positioning the probe against an anterior wall of the catheter, away from a posterior vessel wall on which the catheter lies.  In a second embodiment, a portion of the support tube extends outside the distal end of the catheter to prevent any possible contact between the sensing element and posterior vessel wall.

Title: Radiofrequency heating of thin filaments
Inventor: HOCKING MICHAEL G
IPC: H05B6/02
Filed: 1991-02-06
Abstract: A radiofrequency heating apparatus for heating a linearly supported thin electrically conductive filament (10) comprises a coil (15), earthed at one end, located adjacent to the filament; and a source (12) of radiofrequency (RF) signals in the frequency range from H.F. to U.H.F. connected to the coil. A conducting element (16) is connected to the non-earthed end of the coil (15) and arranged to form or lie on the surface of a cylinder (11) through which the filament (10) passes coaxially whereby the heating of the filament occurs within the cylindrical conducting element (16) and the RF signals are amplitude modulated. Preferably the modulation applied to the RF source is within the audio frequency band, conveniently double or single sideband modulation. The source of modulation may be pulsed and preferably the radiofrequency is approximately 13,56 MHz.
Patent CA-2081894-A1 (CA)
Inventor: JOSEPHSON LEE
IPC: G01R33/28
Filed: 1991-05-03
Abstract: A new ligand binding assay is based upon measurements of relaxation rates of the solvent, which are obtained with a magnetic resonance (MR) spectrometer. It is termed a solvent mediated relaxation assay system (SMRAS). SMRAS is based on the observation that the enhancement of proton relaxation rates produced by a magnetic material can be modulated by the binding of various analytes to a magnetic material. Hence the relaxation rate of the solvent can be interpreted to give information on the concentration of an analyte.

Title: Providing a uv curable protection strip on a business form
Inventor: GOLEMO JOHN C
IPC: B41M5/124
Filed: 1992-12-04
Abstract: ABSTRACT      Business forms, particularly financial instruments such as checks, money orders, bank drafts, etc., are constructed with CF and CB, or self-imaging, sheets.  MICR characters may be printed on the sheets without subsequent smearing by applying a W curable ink to a CF or self-imaging sheet so as to block the CF or self-imaging material at the selected portion to which the ink is applied, thereby rendering it incapable of functioning as a CF or self-imaging element.  The ink is applied to a moving web in a continuous manner prior to printing to form a continuous strip of ink, which moves past a W radiation source so that it is quickly cured and does not adversely affect high speed production.  The ink may also be applied to a CB, CF, or self-imaging sheet as a security feature, selectively blocking the transmission of confidential indicia at the selected portion of the sheet with which it is associated.

Title: Hepatitis c virus asialoglycoproteins
Inventor: MARCUS FRANK
IPC: C12N15/51
Filed: 1991-11-07
Abstract: Two Hepatitis C Virus envelope proteins (E1 and E2) are expressed without sialylation. Recombinant expression of these proteins in lower eukaryotes, or in mammalian cells in which terminal glycosylation is blocked, results in recombinant proteins which are more similar to native HCV glycoproteins. When isolated by GNA  lectin affinity, the E1 and E2 proteins aggregate in-to virus-like particles. Cells bearing a mannose receptor or asialoglycoprotein receptor are capable of being infected with HCV, and supporting culturing of the virus.

Title: Fuel bundle for a heavy-water moderated thermal breeder
Inventor: DASTUR ADI R
IPC: G21C7/27
Filed: 1993-06-28
Abstract: ABSTRACT   A method and apparatus is described for breeding fissile material in a pressure tube heavy water moderated reactor containing a plurality of fuel bundles, wherein the bundle has a plurality of elongated fuel rods or fuel elements containing fuel material which are mechanically supported therein. A first group of fuel rods containing fertile material is arranged in a first region of the fuel bundle. A second group of fuel rods containing fissile material is arranged in a second region of the fuel bundle such that it surrounds the first region of fertile material. This arrangement results in that the second region of fissile material being relatively impenetrable to thermal neutrons generated in the moderator while exposing the fissile material, initially during an early part of its life in the reactor, to an epithermally rich neutron spectrum to breed fissile material in the second region, while the fissile material is depleted in the first region. The bred fissile material in the second region, is placed in a thermally rich neutron spectrum, to convert the bred fissile material to energy, thereby increasing the amount of energy produced from a fuel bundle over the fuel life.

Title: Magnetic disk drive unit
Inventor: RICHARD DAVID W
IPC: G11B33/14
Filed: 1993-10-19
Abstract: MAGNETIC DISK DRIVE UNIT            Abstract of the Invention:     A high capacity, high speed memory system is presented.  The system comprises a disk drive cartridge and an electronics unit.  The disk drive cartridge comprises five magnetic hard disks having 300 megabytes of usable capacity housed in a hermetically sealed, self-contained unit suitable for use in extreme environments of vibration, shock and temperature.  The electronics unit comprises a metal structure wherein the electronics for the system are housed.  The disk drive cartridge has a temperature sensor mounted on a circuit board of the spindle assembly.  The temperature sensor measures internal temperature of the disk drive cartridge.  This temperature information is used to modify a seek algorithm.  More specifically, to modify drive current levels to the voice coil (since voice coil resistance changes with temperature), to modify head load/unload operation, to modify temperature drift for readings of Hall effect devices, and to better account for flex bias of capton flex circuits.  The disk drive cartridge also has a head loading sensor assembly.  A magnetic flux sensor is disposed on a circuit board which extends over a portion of an arm assembly.  The arm assembly has a permanent magnet therein position to pass under the magnetic flux sensor (e.g., a Hall effect sensor).  Accordingly, as the arm assembly moves the magnetic flux from the permanent magnet detected by the flux sensor will vary.  This has been determined to be a generally linear relationship. Therefore, the position of the arm assembly (more particularly, the permanent magnet in the arm assembly) is tracked by the flux sensor.  Further, the arm assembly has a park or stop position wherein the arm assembly is completely moved away (fully retracted) from the disk.  In this fully retracted position the heads and disk are immune to induced shock and vibration.

Abstract: Abstract The invention provides a spring exerting a non-linear force between a contact carrier and a contact blade in a circuit interrupter. The inventive spring includes at least one elongated cantilever.  The length of the cantilever has the shape of an arch made with a non-uniform angle and is formed from an elastic material.  The cantilever is supported at one end against the carrier with the length of the cantilever positioned parallel to the carrier and the opposite end of the cantilever abutting the contact blade so that the carrier supports more of the length of the cantilever as the displacement between the carrier and the contact blade decreases.          The invention also includes a method of operating a circuit interrupter by non-uniformly increasing the force exerted against a movable contact as it engages a stationary contact to complete a circuit.
