Patent CA-2421674-A1 (CA)
Inventor: MACDUFF JAMES
IPC: B23B5/16
Filed: 2003-03-12
Abstract: A reaming tool for a flexible tubing has cutting blades mounted in a spaced-apart relationship with a base of a shaft that is inserted into an end of the tubing. The blades cut a bevel on an outer periphery of the tubing so that an aluminum layer of a composite tubing is cut back from the end of the tubing to inhibit bi-metal corrosion when a tubing joint is formed using a tubing connector made of copper or brass.

Patent CA-2422534-A1 (CA)
Inventor: GRAHAM ROBERT
IPC: C10G9/28
Filed: 2001-09-18
Abstract: La présente invention concerne un procédé de valorisation des charges d'hydrocarbures lourds par utilisation d'un réacteur de pyrolyse à temps de séjour limité fonctionnant dans des conditions permettant le craquage et la valorisation chimique des charges. Ce procédé consiste à préparer une charge en partie valorisée présentant une viscosité réduite et une densité API supérieure. Ce procédé permet d'éliminer sélectivement les métaux, les sels, l'eau et l'azote de la charge, et à la fois de maximiser le rendement du produit liquide et de minimiser la production de coke et de gaz. Par ailleurs, ce procédé permet de réduire la viscosité de la charge pour le transport par pipeline, si on le souhaite, de la charge valorisée avec très peu ou sans adjonction de diluants. Ce procédé de valorisation d'une charge d'hydrocarbure consiste à introduire un caloporteur particulaire dans un réacteur à circulation ascendante, à introduire la charge d'hydrocarbures lourds dans le réacteur à circulation ascendante à un emplacement situé au-dessus du caloporteur particulaire de façon que le rapport de chargement du caloporteur particulaire soit compris entre 15:1 et 200:1 environ, ce qui permet une interaction entre la charge d'hydrocarbures lourds et le caloporteur avec un temps de séjour inférieur à 1 seconde environ, pour produire un flux, à séparer le flux du caloporteur particulaire, à régénérer le caloporteur particulaire et à récupérer un produit gazeux et liquide à partir du flux. La présente invention concerne également les produits obtenus selon ce procédé.

Title: Sod roll pre-starter
Inventor: BROUWER GERARDUS J
IPC: A01B45/04
Filed: 2003-07-23
Abstract: A pre-starter for starting a turn in the end of a sod strip travelling up a conveyor in a sod harvester. The pre-starter includes a metal plate sloping downwardly and rearwardly with its end pressing against the sod strip to catch the blades of grass on the upper surface of the sod strip, thereby causing the end of the sod strip to curl upwardly.

Title: Method for dosing catalysts
Inventor: GEBHART HERMANN
IPC: C08F10/06
Filed: 2002-01-30
Abstract: The invention relates to a method for dosing catalysts into a reactor, wherein the catalyst is initially suspended in hydrocarbon in a receiving container, the suspension thus obtained is maintained in motion by agitation and fed into the actual reactor via a three-way dosing valve and an ejector. The suspension containing the catalyst is firstly discharged from the receiving container with the aid of a pump and continuously circulated, whereby the suspension is returned to the receiving container via the three-way dosing valve in a closed line system, whereupon the pressure inside the receiving container is adjusted so that it is 0.1 - 30 bars higher than the pressure in the reactor and the suspension is continuously introduced into the reactor by pulsing operation of the by now opened three-way dosing valve by a throughflow measuring device which controls the three-way dosing valve and by a downstream ejector.

Abstract: A column mounted shoring bracket has a support sub-assembly attached to a column or other supporting surface, a jack sub-assembly attached to the support and a head sub-assembly attached to a part of the jack that varies in height relative to the support. The head has a head base that supports one or more rollers for moving a form. The head also has a supporting plate for supporting the form. The supporting plate is connected to the head base so that it may be slid upwards and fixed in a position where the top of the supporting plate is above the top of the rollers, for example to carry the weight of a slab being built, or slid downwards so that the top of the supporting plate is below the top of the rollers which do not have to carry the weight of the slab being built. The angular position of the rollers may be aligned with an external reference such as the side of a column, a wall, or a jig. The bracket is adapted for use with parts of forms that may be made or assembled in or adjusted between a set of widths within a range that differ from each other by a selected increment. The forms include structures for spanning between shoring brackets or other supports that can be pre-cambered so as to have acceptable deflection when loaded.

Abstract: The disclosure describes vapor permeable retroreflective material for use on protective garments. The material may be formed in a non-continuous pattern that provides a high-level of retroreflective brightness, yet also provides adequate permeability to prevent exposure to trapped thermal energy and heated moisture. The non-continuous retroreflective pattern may include retroreflective regions and non-retroreflective regions arranged such that thermal decay through the protective garment is not substantially decreased in the regions corresponding to the retroreflective material. Rather, vapor permeation and thermal decay through the garment may be substantially the same as if the retroreflective material was not present.

Abstract: An apparatus and method are disclosed for purifying a contaminated fluid stream, for example an air stream contaminated with volatile organic compounds. A sorption media (12c) is directed between narrowly spaced plates which control the depth of sorbant flow.

In a desorber the plates (28c, 29c) may be transmissive or reflective of microwave energy (30c) and porous to a purging gas (40c) in a desorption chamber where the media (12c) releases the contaminates to refresh the media (12c). An inclined plane or conical surface is contemplated for a desorber which can be coupled to an adsorber in a closed loop system.
