Abstract: A method for removing a prion from a solution comprising the prion and at least one additional biomolecule, comprising directing the solution through an anion-exchange chromatography column under conditions that cause a gradient elution, whereby the prion is separated from at least one of the biomolecules, thereby causing said biomolecule to be collected in an eluate fraction that is distinct from an eluate fraction that includes the prion. In one embodiment, the gradient is a pH  gradient, for example, a step gradient. The prion can be a causal agent for a spongiform encephalopathy, such as Creutzfeldt-Jakob disease, Gerstmann-Straussler-Scheinken syndrome, scrapie, or bovine spongiform encephalopathy.

Title: Measuring device primarily for use with vehicles
Inventor: HENDRIX BILL
IPC: G01B5/00
Filed: 1997-09-15
Granted: 2005-04-05
Abstract: A system (10) for measuring the points on a vehicle (24) includes reference emitters (14) fixed relative to the vehicle, electromagnetic radiation-emitting probes (18), a camera (16), and a computer (20). The camera (16) senses the direction of the emitter (14) from three different locations so the computer can triangulate to determine the position of the emitter. The position is then put onto a standard coordinate system and is compared to standard data for the type of vehicle to determine the extent of deviation of the measured point from the standard data. This provides real time data to a person who is straightening the vehicle or aligning parts of the vehicle to know when the straightening or aligning is complete.

IPC: G06Q30/00
Filed: 1997-12-19
Granted: 2003-07-29
Abstract: The invention includes a markup language according to the SGML standard in which document type definitions are created under which electronic documents are divided into blocks that are associated with logical fields that are specific to the type of block and that are separately cryptographically signed (Fig. 35). Each of many different types of electronic documents can have a record mapping to a particular environment, such as a legacy environment of a banking network, a hospital's computer environment for electronic record keeping, a lending institution's computer environment for processing loan applications, or a court or arbitrator's computer system. Semantic document type definitions for various electronic document types (including, for example, electronic checks, mortgage applications, medical records, prescriptions, contracts, and the like) can be formed using mapping techniques between the logical content of the document and the block that is defined to include such content. Also, the various documents types are preferably defined to satisfy existing customs, protocols and legal rules.

Abstract: An ATM cell constructor of an ATM transmitter assembles a stream of frames of constant bit-rate traffic received on a listen TDM bus into cell payloads using ATM adaptation layer 1 (AAL1 ). Once every eight cells, the AAL1 structured data transfer (SDT) cell constructor layer introduces a one-octet SDT offset pointer into the payload. This pointer designates traffic-block (TDM frame) boundaries. The payload with an attached ATM header forms an ATM cell, and the constructor transmits a stream of the ATM cells, carrying traffic of one wideband channel, to a receiver. A receiver receives one or more streams of the ATM cells from one or more transmitters. During each frame interval, an ATM cell deconstructor of the ATM receiver disassembles a block's worth of traffic from a received ATM cell of each received stream, assembles the disassembled traffic from every stream into a TDM frame, and transmits the frame on a talk TDM bus. In response to commencing to disassemble a whole block's worth of traffic from an ATM cell that includes the SDT offset pointer, the deconstructor adjusts the disassembling to commence the disassembling of the whole block's worth of traffic at the block boundary pointed to by the SDT offset pointer, thereby aligning frames on the talk TDM bus with the frames on the listen TDM bus. The listen and talk TDM buses are thereby synchronized with each other.

Abstract: L'invention concerne un procédé pour produire un nombre aléatoire selon des principes de mécanique quantique, et un générateur aléatoire servant notamment à mettre en oeuvre ledit procédé. L'invention est fondée sur la sélection de trajet fondamentalement aléatoire d'une particule quantique sur un séparateur de faisceaux (8, 18). Des détecteurs (D1, D1', D2, D2') servant à détecter les particules sont associés aux sorties (11, 12, 16, 17) du séparateur de faisceaux (8, 18). Ces détecteurs ou leurs événements de comptage représentent différentes valeurs numériques de la séquence aléatoire. La production d'un état à particules multiples dans le canal de sortie (11, 12, 16, 17) du séparateur de faisceaux (8, 18) ainsi que plusieurs particules arrivant sur le détecteur (D1, D1', D2, D2') permettent d'améliorer considérablement de manière avantageuse la probabilité de réaction du détecteur et par conséquent la probabilité d'obtenir un événement de comptage valorisable pour chaque état à particules multiples produit par la source (3, 3'). Il est ainsi possible d'obtenir la séquence aléatoire plus rapidement et de manière plus fiable qu'avec une détection de particules uniques.

Abstract: A single tool is provided to score the surface of aluminum or vinyl siding regardless of profile. The tool comprises an extensible measuring rail at the end of which is attached a scoring knife, the rail and knife being extensible from a siding guide which interlocks solely with the edge of the siding material. The measuring rail is spaced above the guide for spacing the rail and scoring blade above the surface of the siding material, thus avoiding undesirable damage to the surface as it is engaged in the tool and as the tool is drawn down the edge of the siding during scoring. The scoring knife is pivotable on the measuring rail so as to contact with the siding surface when under control of the installer and regardless of the siding profile. Further the knife is reversible for use by both right and left-handed installers.

Title: Oxidase process for pulp and dye oxidation
Inventor: PAICE MICHAEL G
IPC: D06P5/15
Filed: 1999-04-13
Granted: 2005-09-27
Abstract: This invention describes a novel method for selectively delignifying lignocellulosic materials and bleaching of pulp and dyes using a combination of an oxidative enzyme and a metal complex. More specifically, the process involves the oxidation of a transition metal redox complex by a phenol oxidizing enzyme such as laccase or peroxidase to mediate the catalytic delignification of chemical pulp and bleaching of textile dye. This process is unique in that only a catalytic amount of metal complex mediator is required on softwood or hardwood kraft pulp, and that recycling or regeneration of the mediator for further pulp delignification is possible. The redox mediator is characterized in that it contains a transition metal ion coordinated with molecules or ions in such a way that the complexes have a formal redox potential between 0.5 and 1.2 volt measured against a normal hydrogen electrode.

Abstract: A nonwoven composite is formed by hydroentangling a fibrous web into a nonwoven base web and subsequently treating the hydroentangled webs with a textile-treating agent selected from silicones, derivatives of silicones and quaternary ammonium compounds.  The nonwoven base web, which may be made of polyester, polypropylene or polyamide fibres, may be formed on a card and subsequently needled or hydroentangled, or it may be a spunbonded web. The fibrous web, which may be formed by a wetlaid or airlaid process, may be made from pulp prepared from wood fibres and/or vegetable fibres such as abaca, sisal or jute; alternatively, synthetic fibrous webs, e.g. of aramid, nylon or rayon, could be used. The textile-treating agent may be applied in an amount of from 3 to 7% by weight of the solids in the untreated composite. The nonwoven composite may be used as a lining between the body of a moulded article, for example an interior panel component for a motor vehicle, and a decorative facing material supported by the said body.
