Patent CA-2186670-C (CA)
Inventor: THALER KEN
IPC: E04D13/14
Filed: 1996-09-27
Granted: 1999-01-19
Abstract: The invention provides a quickly installed and preferably reusable flashing unit for use in roofing or cladding of a building. The flashing is constructed of stainless steel sheet metal for superior corrosion resistance and to withstand rough handling as old roofing material is scraped off the flashing surfaces to prepare it for reuse. The flashing is assembled along joints between assembled flashing components. Each joint includes a resilient gasket between opposing edges of adjacent flashing components. Clips join the components together and resiliently compress the gasket between opposing edges of the adjacent components. After assembly around stacks, openings, edges or other roofing discontinuities, the flashing is incorporated into the roofing in a conventional manner. The invention provides, in its broad aspect, a novel flashing unit for weatherproofing a discontinuity in an external weatherproof membrane, said flashing being assembled along at least one joint, a portion of said joint being covered by said membrane, said flashing comprising: first and second components, each component having an opposing edge disposed at a distance from the opposing edge of the other component, thus defining said joint; gasket means, abutting each said edge, for resiliently sealing said joint; and clamp means, for joining said components and for sealingly compressing said gasket between said opposing edges. Three variations of the gasket and clamp means are described herein.

Title: The use of nitrogen from an air separation plant in carbon dioxide removal from a feed gas to a further process
Inventor: OCCHIALINI JAMES MICHAEL
IPC: F25J3/04
Filed: 1996-09-27
Granted: 2001-01-02
Abstract: A cryogenic air separation unit (ASU) provides flows of oxygen and nitrogen. Theoxygen is used in a process such as COREX iron making or the partial oxidation of hydrocarbons, or in an oxycoal fuelled blast furnace, producing an off-gas containing useful components (H2 and CO) and carbon dioxide. The carbon dioxide is removed by pressure swing adsorption using nitrogen from the ASU as a regeneration gas and the purified off-gas becomes a feed gas to a further process such as production of iron by direct reduction of iron ore or the production of a NH3 making ammonia or is recycled into the first process as a feed gas.

Abstract: A portable sports shed is adaptable for resting on the ground or for residing within the bed of a pick-up truck. The shed has a lower section which is sized to fit within the truck bed, and a wider upper section that has side walls and a transversely arcuate roof. Laterally extending bench sections interconnect the lower and upper sections. Each end wall of the shed has a pair of doors providing access to the shed and the floor has at least three parallel grooves therein which define skids on the exterior bottom. The grooves will accept the skids of a snowmobile or the wheels of an ATV, a lawn and garden tractor or one or more bicycles or motorcycles. When the shed is mounted in the truck it can protect a vehicle housed therein from the elements or it can be used as a camper. When resting on the ground it acts as a garage, permitting a vehicle to be driven in via one set of doors and out via the other set of doors. Trapdoors in the floor permit the shed to be used as an ice fishing hut and openings in the roof and side walls permit it to be used as a hunting blind or a playhouse. It can also be placed in water to act as a boathouse for a small dinghy or a personal watercraft.

Title: Commande de pompe de puits
Inventor: DUTTON ROBERT E
IPC: E21B43/12
Filed: 1997-04-04
Granted: 2003-12-02
Abstract: Le fonctionnement d'un système de commande d'installation de pompage sur puits pétrolier (20, 200) est déterminé par une unité de commande automatisée par ordinateur (88) qui reçoit des mesures du débit d'un débitmètre à effet de Coriolis (28). L'unité de commande arrête une pompe à balancier (22) lorsque les mesures fournies par le débitmètre à effet de Coriolis indiquent une baisse de rendement de la pompe. Cette baisse de rendement signale que le niveau du liquide à pomper (136) dans le tubage de production (108) se situe plus bas que le point mort haut du piston de la pompe (122). La production est arrêtée à ce moment-là pour laisser la pression interne du gisement remonter suffisamment pour que le liquide puisse retrouver le niveau auquel la production peut être relancée.

Title: Modified mcm-56, its preparation and use
Inventor: CHESTER ARTHUR WARREN
IPC: C01B33/38
Filed: 1997-06-09
Granted: 2008-01-08
Abstract: A layered composition of matter, MCM-56, has an X-ray diffraction including the lines listed in Table (II) and has been selectively modified so that the ratio of the num-ber of active acid sites at its external surface to the number of internal active acid sites is greater than that of the un-modified material. When used as an additive to a large pore zeolite catalyst in the catalytic cracking of a petroleum feedstock, the modified MCM-56 gives an improved gaso-line yield/octane relationship, an improved coke selectivity and a higher combined gasoline and potential alkylate yield than an identical catalyst containing unmodified MCM-56.

Title: Pressure-responsive lockout valve and method of use
Inventor: WILLARD STEVEN N
IPC: A61F2/26
Filed: 1997-07-28
Granted: 2004-10-19
Abstract: A lockout valve for an inflatable penile prosthesis which responds to internal fluid pressure. The lockout valve comprises a housing having inlet and outlet ports, an interior chamber, an apertured valve seat, and a poppet biased toward the closed position. The inlet communicates with the prosthesis reservoir, and the outlet communicates with the interior chamber and the prosthesis pump. The housing includes a flexible diaphragm which moves toward the poppet when flexed inwardly. Fluid pressure through the inlet port urges the poppet into sealing engagement against the valve seat, therefore closing the lockout valve. Negative fluid pressure applied to the interior chamber from the outlet port (when the pump is actuated) causes the diaphragm to flex inwardly and contact the poppet to open the valve. The lockout valve operates like a check valve when subject to reverse flow.

Abstract: L'invention concerne l'assemblage de produits plats métalliques se chevauchant. Pour ce faire, on introduit les produits plats dans l'écartement formé entre deux cylindres à un angle aigu. Avant d'être pressés l'un contre l'autre entre les deux cylindres, ils sont chauffés par énergie rayonnante au niveau des surfaces se faisant face, sans être fondus. Par un profilage approprié du bandage d'au moins un cylindre ou d'un produit plat, la pression superficielle est limitée à la zone du joint à recouvrement, empêchant ainsi un flux de matière transversalement à la direction du joint de recouvrement.
