Filed: 1992-11-23
Abstract: 2122899 9309711 PCTABS00022 A near-infrared quantitative analysis instrument (10) for measuring a constituent of a sample material is disclosed which effectively utilizes energy in the 1200 to 1800 nanometer wavelengths regions by isolating and employing harmonic wavelengths emitted by typical, low cost commercially available light emitting diodes (LEDs) (16, 17) or infrared emitting diodes (IREDs) (16, 17). The analysis instrument (10) utilizes these very desirable wavelength regions for quantitative analysis measurements by interposing suitable narrow bandpass filters (26, 27) which permit passage of only the selected harmonic wavelengths.

Title: Thrombectomy method and apparatus
Inventor: CRAGG ANDREW H
IPC: A61B17/22
Filed: 1994-07-21
Abstract: A thrombectomy system for dissolving a soft fibrinous obstruction, such as a recently formed thrombus, within a patient's vascular system, either in a patent vein or artery or in a prosthetic implant, employing a soft rotating brush for separating and mixing the fibrin of the thrombus while a dissolving agent, e.g. streptokinase or urokinase, is introduced and mixed in and applied to the separated fibrin.      The system includes an introducer catheter adapted to be introduced and advanced through a patient's blood vessels until the distal end is positioned adjacent the soft fibrinous thrombus, the brush attached to an elongated, flexible, rotatable drive shaft having a drive motor attached at its proximal end, the drive shaft and brush passed through the introducer lumen to place the brush in contact with the soft thrombus. The brush has soft, flexible bristles extending outward from the drive shaft distal end, the bristles being sufficiently resilient and dimensioned for enabling compression and passage of the brush out of and back into the distal end of the introducer lumen and effective to mix into then fibrin of the soft thrombus, yet not damage the vessel wall. The dissolving agent is introduced during rotation of the brush either through the introducer catheter lumen or a drive shaft lumen and out exit ports at the distal ends thereof in the region of rotation of the brush for dissolving the soft thrombus as it is contacted by the bristles. Optionally, a balloon catheter or a mesh basket may be coaxially introduced through the drive shaft lumen and placed downstream to restrain fragments and to allow the dissolving agent to complete the dissolution thereof.

Title: Technique for reducing the molecular weight and improving the processability of high cis-1,4-polybutadiene
Inventor: CASTNER KENNETH F
IPC: C08F2/06
Filed: 1995-03-06
Abstract: Cis-1,4-polybutadiene can be synthesized by polymerizing 1,3-butadiene monomer with a three component nickel catalyst system containing (a) an organonickel compound, (b) an organoaluminum compound, and (c) a fluorine containing compound. However, the molecular weight of the cis-1,4-polybutadiene prepared is typically too high to be utilized as a non-oil extended rubber. This invention is based upon the discovery that para-styrenated diphenylamine acts to reduce the molecular weight and to improve the processability of cis-1,4-polybutadiene prepared with such nickel based catalyst systems. The use of para-styrenated diphenylamine as a modifier in such polymerizations does not change the microstructure of the cis-1,4-polybutadiene produced. Accordingly, the present invention specifically discloses a process for producing cis-1,4-polybutadiene having a reduced molecular weight and improved processability which comprises polymerizing 1,3-butadiene in the presence of (a) an organonickel compound, (b) an organoaluminum compound, (c) a fluorine containing compound, and (d) para-styrenated diphenylamine; wherein the organoaluminum compound and the fluorine containing compound are brought together in the presence of the para-styrenated diphenylamine. Since para-styrenated diphenylamine is an excellent antidegradant, it also provides the rubber synthesized in its presence with antioxidant protection.

Title: Tank connector construction
Inventor: SYLER RODNEY R
IPC: B65D90/00
Filed: 1995-06-05
Abstract: A tank connector assembly including a metal spud member having an internally threaded portion and a cylindrical wall portion. An insert member of polymer material having a cylindrical wall portion. The insert member is mounted inside the cylindrical wall portion of the spud member. A bonding member of polymer material fits the cylindrical wall portion of said bonding member positioned between the external surface of the cylindrical wall portion of the insert member and the internal surface of the cylindrical wall portion of the spud member. The cylindrical wall portion of said bonding member being securely bonded to both the insert member and the spud member. In a preferred embodiment, the polymer material of the bonding member is maleated olefin. The bonding of the cylindrical wall portion of the bonding member to the polymer insert and the steel spud will prevent or at least substantially reduce any tendency of the water in the tank to leak past the outer surface of the insert member which, in turn, prevents water from coming into contact with the wall of the steel tank. Such contact if allowed to occur may cause corrosion of the steel tank. The bond between the outer surface of the cylindrical wall of the bonding member and the steel spud prevents water from coming into contact with the steel spud to thus prevent corrosion of the spud.

Patent CA-2160834-A1 (CA)
Inventor: SANKEY BRUCE M
IPC: C10G9/00
Filed: 1995-10-18
Abstract: A process for the thermal conversion of the organic component of naturally occurring carbonaceous material such as tar sands or oil shale. The conversion is achieved by subjecting organic component, in the presence of about 1 to 20 wt.% native solids, to thermal conversion at temperatures from about 425 to 565°C. Compared to conventional visbreaking, much higher conversion of heavy components can be achieved, primarily because of the presence of the native solids on which coke is deposited instead of fouling the process equipment. The higher conversion is also associated with enhanced removal of sulfur and metals.
