Patent CA-2245479-A1 (CA)
Title: Apparatus and method for extracting and replacing buried pipe
Inventor: NIKIFORUK NICK C
IPC: F16L55/165
Filed: 1998-08-21
Abstract: A pipe/pulling frame is fitted to the tool end of a movable boom of an excavator, preferably visa a quick-attach coupling. The boom first positions the frame in and out of the pit and then secondly holds the frame against twisting movement in the pipe-extraction pit during pulling, thereby obviating the need to provide shoring and other bracing. The frame comprises an actuator and a single reaction plate. The actuator pulls a segmented cable which extends through the pipe while the reaction plate structure bears against the pit wall. The actuator is further operable also to push a stuck pipe, for which the reaction structure is moved to the opposing end of the frame. A swivel is preferably fitted between the tool end and frame to allow the excavator to be positioned independent of the frame. An abutment member at the distal end of the old pipe is replaceable with a ground- reaming tubular pipe for pushing the trailing end of the old pipe and pulling the leading end of a new pipe. The quick-attach coupling at the tool end accepts an excavation bucket to dig the pits, the frame for pulling the pipe, and a ripper tooth to rapidly pull lengths of old pipe from the ground once the force needed falls off.

Title: Method for determination of nucleic acid sequences and diagnostic applications thereof
Inventor: DUNN JAMES M
IPC: C12Q1/68
Filed: 1997-04-29
Abstract: Sequencing reactions are performed directly on complex DNA mixtures, such as the products of multiplex amplification reactions, which could not previously be used for sequencing without intermediate amplification and/or purification to increase the amount of target DNA present relative to other DNA species.  The positions of at least one base within a selected region of a target nucleic acid polymer in a complex mixture of DNA are determined by combining the mixture with a reaction mixture comprising all four types of deoxynucleotide triphosphates, one type of dideoxynucleotide triphosphate corresponding to the base to be determined, first and second primers and a thermally stable polymerase enzyme which incorporates dideoxynucleotides into an extending nucleic acid polymer at a rate which is no less than about 0.4 times the rate of incorporation of deoxynucleotides in an amplification mixture for a plurality of amplification cycles to form a reaction mixture, said first and second primers binding to the sense and antisense strands, respectively, of the target nucleic acid polymer for amplification of the selected region; exposing the reaction mixture to a plurality of temperature cycles each of which includes at least a high temperature denaturation phase and a lower temperature extension phase to produce a product mixture comprising sequencing fragments which are terminated by incorporation of the dideoxynucleotide; and evaluating product mixture to determine the lengths of the sequencing fragments produced. This method can be used as part of a diagnostic method for analyzing a plurality of regions within a nucleic acid-containing sample for the presence of mutations by first performing a multiplex amplification reaction on the nucleic acid-containing sample using a plurality of primer pairs, one pair for each of the plurality of regions to be analyzed to produce a mixture of amplified fragments. The fragments are analyzed in accordance with the experimental protocol being employed, for example by a fragment length analysis. Thereafter, sequencing determinations are made by combining at least one aliquot of the mixture of amplified fragments with a sequencing mixture.

Inventor: SHANKOFF THEODORE A
IPC: C03C25/1065
Filed: 1999-05-07
Abstract: An improved method for coating optical fibers. By practicing the disclosed method, one can loosely couple a polymeric coating to an optical fiber segment. The method includes interposing a nonpolar material between a polymeric coating and an optical fiber segment, both of which usually present mostly polar groups. Such a nonpolar material may be interposed between the coating and the fiber segment either by adding a mold release agent to the polymeric system before it is applied to the optical fiber or by coating the outer surface of the optical fiber with a mold release agent. Alternatively, one may chemically treat the outer surface of the optical fiber so that instead of presenting polar groups to any subsequently-applied polymeric coating, the optical fiber segment presents nonpolar groups, which are not attracted to the polar groups of the polymeric coating. A coated optical fiber segment is also provided that contains a nonpolar material interposed between the polymeric coating and the optical fiber segment. Alternatively, a coated optical fiber is provided that includes a treating material having both polar and nonpolar groups, and which is interposed between the optical fiber and the polymeric coating and wherein its polar groups are attracted to the polar groups of the optical fiber segment and its nonpolar groups are not attracted to the polar groups of the polymeric coating. A coated optical fiber is also provided wherein the optical fiber has been chemically reacted to present a plurality of nonpolar groups to a subsequently-applied polymeric coating.

Abstract: L'invention concerne un système et un procédé de traitement de données qui peut être utilisé pour configurer ou développer des logiciels. Cette invention trouve des applications particulières dans la conception de systèmes d'entreprise permettant une adaptation d'échelle, dans lesquels une pluralité d'objets ou d'entités de codes de programmes sont construits progressivement pour informatiser des processus d'entreprise. Un problème associé avec les technologies de programmation existantes orientées objet est le manque de flexibilité de l'interface entre les objets. Ce manque de flexibilité vient des paradigmes du passage direct des paramètres ou des messages auxquels de tels langages font appel pour produire des logiciels réutilisables. Toutefois, cette approche pose le problème, de déterminer quel logiciel doit être re-développé, en particulier quand l'ordre d'exécution des objets exécutant différentes fonctions doit être changé. Un tel changement dans l'ordre d'exécution nécessite invariablement des modifications des interfaces de passage des codes, des paramètres ou des messages opérant sur des objets ou des entités de programme. Ces changements nécessitent également une recompilation et des reconnexions avant que le processus d'entreprise complet ne puisse être mis en oeuvre. Dans ces conditions, la présente invention fournit un procédé de traitement des données et un système correspondant, comprenant une mémoire pour enregistrer une pluralité d'entités exécutables, de moyens pour établir un ordre d'exécution d'entités sélectionnables parmi les entités exécutables et un moyen pour exécuter les entités exécutables sélectionnés selon ledit ordre, sans modification desdites entités exécutables sélectionnées.

Filed: 1999-07-14
Abstract: A machine, a method, and an air-cooled cutting brush for removing tread material for recycling from used motor vehicle tires prior to scrapping or retreading without damaging the tire cords and beads. The tread material is removed as fine particles, or buffings, ready for recycling without subsequent sorting out of cloth or metal. A tire is mounted in an upright position on a tire receiving assembly which expands to grip the tire beads. The tire receiving assembly is mounted on a supporting structure which pivots. An elongate, powered, rotating, cutting brush is mounted on a rolling mounting structure which moves the cutting brush into and out of engagement with the tread on the outer, ground-contacting portion and on the sidewalls of a tire. In operation, the tire is rotated as the cutting brush engages the tread material of the ground-contacting portion, the supporting structure is then pivoted to remove the tread material of one sidewall, and repeated on the opposite sidewall. The cutting brush is maintained at a temperature below the melting point of the tread material by radially-extending bristles that are twisted and crimped along their length to allow bristles to abut or engage other bristles and allow air circulation between the bristles and to provide even cutting. The machine can be mounted on a tractor-trailer rig for mobile operation, the cutting brush being powered by an internal combustion engine with the tractor having retractable stabilizer arms and a crane to lift tires. A retractable screw auger deposits removed tread material into a container beside the trailer.
