Abstract: A process for reforming a hydrocarbon with carbon dioxide using a selectively permeable membrane reactor including a catalyst 1 for accelerating a chemical reaction and a selectively permeable membrane 3 exhibiting selective permeability, wherein a carbon dioxide reforming reaction of the hydrocarbon is accelerated by the catalyst 1 and a specific component among reaction products produced by the reaction is selectively separated by allowing the specific component to pass through the selectively permeable membrane 3, the process including adding steam to a raw material gas containing the hydrocarbon and the carbon dioxide and supplying the mixture to the selectively permeable membrane reactor. According to the present invention, inactivation of the catalyst due to coking can be prevented when carrying out the carbon dioxide reforming reaction of the hydrocarbon using the permeable membrane reactor, whereby the reaction can be efficiently and stably carried out over a long time.

Title: Prediction of shallow drilling hazards using seismic refraction data
Inventor: KELLOGG STEPHEN C
IPC: G01V1/36
Filed: 2005-02-28
Granted: 2008-12-09
Abstract: Shallow drilling hazards (44), such as karsts, caves, voids and unconsolidated discontinuities, that can pose significant risks to exploration and development well drilling operations are detected employing seismic refraction data on which a series of attribute analyses are performed, the resulting data being further processed to provide a three-dimensional visualization. Refracted wave raypaths (40, 46, 48) are highly distorted by encountering a karst feature with the occurrence of backscattering absorption.  The resultant energy recorded at the surface receivers (52) is significantly reduced as compared to refracted waves recorded by other receivers (50) where no karsting is present. Multiple refractors are subjected to a relatively simple and rapid processing using commercially available software to track these differences and to map them in the near surface to improve the siting of wells and to alert drilling engineers and crews to the possibility of encountering the hazard.

Abstract: A stent delivery system that helps equalize delivery forces throughout a vascular prosthesis during delivery thereof to an intended treatment site. The delivery system comprises a catheter having a lumen therethrough, an inner core over which the one or more stents or stent grafts is mounted for delivery from the catheter, and an outer sheath overlying the one or more stent or stent graft and the inner core. The inner core of the further comprises a series of outwardly flared members that engage segments or fill voids in or between the stent, stents or stent grafts, respectively. The outwardly flared members of the inner core thus help maintain the segments of the stent or the one or more stents or stent grafts in spaced relation with respect to one another as delivery thereof occurs and as removal of the outer sheath occurs to position the one or more stents or stent grafts at the intended treatment site. The outwardly flared members thus help to distribute delivery forces more evenly throughout the one or more stents or stent grafts being delivered from the catheter. The outwardly flared members further aid accurate placement of the one or more stents or stent grafts by maintaining longitudinal spacing thereof during delivery.

Abstract: There is a general need for improved efficiencies in the bitumen and heavy oil recovery and extraction industry. The present invention is directed to a method and system for integrating an in-situ bitumen recovery operation with a bitumen mining operation for improved efficiencies and synergies therebetween. The method comprises the basic steps of obtaining a production fluid from the in-situ bitumen recovery operation, directing the production fluid to the bitumen mining operation, and incorporating the production fluid into the bitumen mining operation. The basic integrated system comprises a production well for recovering production fluid from the in-situ bitumen recovery operation, a bitumen mining and extraction facility, and a transporter for directing the production fluid from the production well to the bitumen mining and extraction facility for incorporation into the mining and extraction operation. The in-situ recovery operation may be a thermal operation, such as steam-assisted gravity drainage (SAGD), cyclic steam stimulation (CSS), or a derivative thereof. The integrated method and system of the present invention provide the potential to reduce capital investment, operating costs, overall land footprint and fluctuations in mine production, compared with stand-alone in-situ recovery and mining operations. The integrated method and system of the invention also provide the potential for commercial development of smaller scale in--situ recovery operations.

Abstract: A portable, potable-water generator for producing high-purity liquid water by condensation of water vapor from ambient air. The generator (125) employs an air filter (119) to remove particulates and aerosols from the incoming air. An enclosed heat absorber cools the filtered air to its dew point and collects droplets of condensate into a condensate collector (5). Before discharge, the collected dew is treated in a bacteriostat loop to destroy adventitious living organisms and to filter out undesirable and dangerous contaminants. A recirculation loop provides the ability to recirculate stored condensate, including during periods of inactivity. Further, quick disconnect fittings (55b) and variable length flexible tubing allows use of the invention to serve remote dispensers and/or appliances and allow use of municipal water treated through the apparatus in low condensate situations.

Abstract: A safety system, attached to the underside of a access (lid, cover, grill, grate, or hatch), that allows the user to mount and dismount a ladder below in an ergonomically friendly and safe manner. The safety system comprises of a locking device (post member) and two handrails attached to the underside of the access cover. This locking device (post member) has a weighted latch on top that holds it in a stored un-operational position until needed. The handrails are attached in line with the manhole ladder handrails. When the access cover is in a vertical open position the locking device (post member) can slide down into a stationary hollow receiver sleeve that is in a permanent fixed position below the surface of the access cover. This secures the access cover in a vertical open position, allowing the user to utilize the handrails on the underside of the access cover as an extension of the ladder that is affixed below the surface of the access cover.
