Patent CA-1340806-C (CA)
Inventor: ROBERTSON CHARLES WILLIAM JR
IPC: C12Q1/68
Filed: 1987-06-30
Granted: 1999-11-02
Abstract: A DNA sequencing system and method are described to detect the presence of radiant energy emitted from different excited reporter dye-labeled species (DNA fragments) following separation in time and/or space, and the identity of the species which emit radiant energy closely spaced in wavelength.      Functions of the emitted energy are obtained which vary over the wavelengths of the closely spaced spectra in different senses and the functions ratioed, whereby the ratio is indicative of the identity of the DNA fragments.      The emitting portion of the reporter-labeled DNA fragment is preferably one of a family of fluorescent dyes based on 9-carboxyethyl-6-hydroxy-3-oxo-3H-xanthene. These xanthene dyes are covalently attached to the DNA fragments through the carboxylic acid functionality, preferably via an amide linkage.      The dyes may be protected by including an alkoxy group at the 9-position. A spacer may be inserted between the dye and the amine. The fluorescent dye preferably is attached to the DNA chain terminators and provides many advantages. Thus only DNA sequencing fragments resulting from bona fide termination events will carry a reporter. The DNA sequencing may also be labeled using the xanthene dyes which have general utility as fluorescent labels. Also acyclonucleoside triphosphates are described as being useful as chain terminators in DNA sequencing using a modification of the Sanger method.

Abstract: PRODUCTION OF IMPROVED PREIMPREGNATED MATERIAL COMPRISING A PARTICULATE THERMOPLASTIC POLYMER SUITABLE      FOR USE IN THE FORMATION OF A SUBSTANTIALLY VOID-FREE FIBER-REINFORCED COMPOSITE ARTICLE            Abstract of the Disclosure An improved multifilamentary fibrous material is formed having particles of a matrix-forming thermoplastic polymer substantially uniformly dispersed among adjoining filaments in the absence of fusion bonding.  The polymer particles initially are dispersed in an aqueous medium containing an effective amount of a dissolved polymeric binding agent and the viscosity of the medium subsequently is substantially increased to at least 50,000 cps. to form a gelled impregnation bath having a plastic flow characteristic with shear-thinning behavior wherein the polymer particles are substantially uniformly suspended.  The resulting impregnation bath is caused to flow between the adjoining filaments of the multifilamentary fibrous material with a concomitant viscosity reduction which aids in the incorporation of the polymer particles. The concentration of the aqueous medium in the product is controlled to yield a uniform, handleable, drapable, tacky, and highly stable product.  Upon the application of heat and pressure the improved product can be transformed into a fiber-reinforced composite article wherein the solid particles form the matrix phase.

Abstract: ABSTRACT OF THE DISCLOSURE         Basic nitrogen compounds (BNC) are selec-tively removed from solvent extracted oils by adsorp-tion of said BNC's by solid acidic polar adsorbents. The oils are extracted using any of the common extrac-tion solvents,  such as furfural,  phenol,  SO2, N-methyl-2-pyrrolidone  (NMP),  preferably NMP.   The resulting raffinate, which contains the desirable oil fraction, has the BNC's present therein removed by adsorption thereof onto an adsorbent, characterized as being a solid, polar acidic adsorbent, exemplified by silica-alumina, a high alumina base amorphous cracking catalyst (such as manufactured by Ketjen/Akzo) and crystalline zeolite (such as H-Y zeolites) are effec-tive adsorbents.  The adsorbents may additionally con-tain fluorine or may contain up to 30 weight percent water.  The adsorbents are regenerated by either purg-ing with hydrogen at elevated temperature and pressure, or by washing the BNC saturated adsorbent with extrac-tion process extraction solvent, such as NMP.           Extracted oil raffinate treated with the adsorbent to remove BNC exhibit superior uninhibited oxidation stability as compared to untreated conven-tional hydrofined oil.

Title: Damper blade seal
Inventor: DAVIS JAMES A
IPC: F24F13/10
Filed: 1988-01-21
Granted: 1991-12-10
Abstract: Title DAMPER BLADE SEAL         Inventor James Allen Davis Abstract A rectangular damper blade rotates about its longitudinal center line between an open and closed position to control the airflow entering an enclosure.  Two longitudinal edges of the damper blade become positioned between two inlet edges of the enclosure as the blade rotates to the closed position.  The blade is associated with two longitudinal seals. One seal is attached directly to one of the blade's longitudinal edges and provides wiping contact against one of the inlet edges. The other seal is attached to the other inlet edge and provides wiping contact against the blade's other longitudinal edge.  Both seals have similar cross-sections to facilitate their inter-changeability.  And both seals include a flexible lip that extends upstream and perpendicular to the blade to enhance the sealing force and to minimize wiping friction.  In the presence of an air pressure differential across the damper blade, the seals urge the blade to the closed position, and when closed, exert a radial sealing force generally parallel to the blade. The configuration of the seals provides a damper that is tolerant of misalignment which makes it suitable for direct drive actuation.

Abstract: Frame Synchronization Detection System for Time Division Multiplexed (TDM) Digital Signals Abstract A frame synchronization detection system which enables frame synchronization and sychronizing pulses to be provided from at least two formats of DSl TDM signals, specifically the D4 and extended superframe Fe formats.  A single sequencer is used to provide repetitive sequences of bits spaced apart by a predetermined multiple of the number of bits in a frame, specifically for the D4 and Fe formats, 772 bits.  It has been found that framing patterns 772 bits apart contain information as to the location of the framing bits notwithstanding that in the D4 format there is a framing bit for each frame and in the Fe format only certain frames contain framing bits.  These framing patterns are applied to a pattern decoder which provides outputs upon detection of the D4 and Fe patterns in parallel, whichever may occur.  A first search logic circuit provides an output indicating the onset of a maintenance mode of frame detection when either Fe or D4 patterns are decoded. For the D4 pattern an alternate pattern is decoded and the first search circuit has means for entering the maintenance mode only after both alternate D4 framing patterns are decoded.  A second search logic circuit enables the decoding of a

Granted: 1992-04-07
Abstract: ABSTRACT OF THE DISCLOSURE      Self-supporting raised floor plates of flat construction, with an outside wrapper consisting of a flat metal shell which is open at the top for a mineral, age-hardenable filler material, for instance anhydrite, are known.  However, with such raised floor plates of flat construction, the embedding of an electric heating line in the layer of mineral material so that the heating line is found without interference in the statically neutral zone of the raised floor plate is problematic.  The invention overcomes this problem in that the heating line is fastened to holders arranged over the bottom of the shell.  These holders are fastened by clamping by means of a plug-like member in selected anchoring openings in the bottom of the shell.  The heating line is clipped or respectively snapped into slots in the head segments of the holders.

Abstract: An improved method of presulfiding a hydro-treating catalyst which minimizes sulfur stripping upon start-up of  a  hydrotreating  reactor utilizing  such a catalyst.  The method comprises the steps of contacting a hydrotreating  catalyst  with  elemental  sulfur  at  a temperature below the melting point of sulfur, thereby forming  a  sulfur-catalyst  mixture,  and  heating  the sulfur-catalyst mixture to a temperature above the melt-ing point of  sulfur.  Preferably,  the sulfur-catalyst mixture is  first mixed with a high boiling oil or a hydrocarbon solvent to form a prewet mixture prior to heating  at a  temperature above  the melting  point  of sulfur.
