Patent number: 8284749Abstract: One or more frame slots to each transceiver are allocated for communication within each message cycle. The number of frame slots allocated can be dynamically adjusted to accommodate variable traffic loads per transceiver, and an offset of the frame slots within the message cycle is preferably predefined to provide a uniform distribution among the transceivers. The design of the transceiver is independent of the particular application, having at least one programmable parameter that controls the number of frame slots allocated within the message cycle. By controlling the number of frame slots allocated to a transceiver, the amount of inactive time, and hence battery life, can be controlled. When a conflict occurs among multiple transceivers having pending messages at the same frame slot, the allocation of the frame slot to a transceiver is based at least in part on the resultant lag time to each transceiver.Type: GrantFiled: March 2, 2009Date of Patent: October 9, 2012Assignee: Comtech Mobile Datacom CorporationInventors: R. Clayton Smith, Luis G. Jordan, Scott A. McDermott

Publication number: 20110124534Abstract: A substantially liquid gellant formed as one or more reaction products of a metal carboxylate or metal carboxylate amine salt, one or more organic acids, an ester which drives the reaction so that the reaction products are asymmetrical in structure, and a rheology modifier which preferentially interacts between the reaction products for prevent solidifying of the gellant reaction products until such time as the gellant is mixed with the fracturing fluid containing an activator after which the reaction products preferentially interact with the activator to gel the fracturing fluid.

Patent number: 7915202Abstract: A clay stabilizer which is capable of inhibiting swelling in a wide variety of clay types and is also capable of restoring permeability in formations which have previously been damaged by clay swelling. Amine salts of differing molecular weights configurations and ionic strength are combined to provide transport into micropores, mesopores and macropores in the formation and to effect cationic change therein. A poly quaternary amine having a high to very high charge density is added along with lower molecular weight amine salts to substantially permanently exchange cations with the clay in the formation.Type: GrantFiled: April 27, 2010Date of Patent: March 29, 2011Assignee: Weatherford Engineered Chemistry Canada Ltd.Inventors: Clayton Smith, Darin Oswald, Michael D Daffin

Publication number: 20100298173Abstract: Anti-accretion additives utilize silicone chemistry to prevent bituminous and heavy oil materials from sticking to metals surfaces such as drill bits, drillstring, casing and the like. Organopolysiloxanes and/or copolymers thereof are added directly to an aqueous drilling fluid or are first diluted in a solvent for adding to the drilling fluid. Further, an alkyl polyalkylene oxide may also be added. If a silicone oil is used as the solvent, the anti-accretion additive has the increased functionality of minimizing the amount of bituminous or heavy oil material which is retained in the drilling fluid when returned to surface and permits removal of the bituminous or heavy oil materials with the solids using conventional solids control equipment.Type: ApplicationFiled: May 13, 2010Publication date: November 25, 2010Applicant: INNOVATIVE CHEMICAL TECHNOLOGIES CANADA LTD.Inventors: Clayton SMITH, Simon John Michael LEVEY, Yonglin (Ginger) REN

Patent number: 7754661Abstract: A method of recovering hydrocarbon or synthetic base oils from used oil-based drilling mud utilizes acid to deactivate emulsifiers in the drilling mud for altering the emulsion stability and permitting removal of the solids contained in the drilling mud using conventional separation such as centrifugation. A surfactant is typically added to prevent water-wetting as a result of the addition of the acid. The recovered base oil contains substantially all of the deactivated emulsifiers, which can be reactivated through the addition of lime, allowing new drilling fluids to be prepared without the need to add significant amounts of emulsifier to the recycled base oil.Type: GrantFiled: November 27, 2007Date of Patent: July 13, 2010Inventors: Clayton Smith, Simon John Michael Levey

Patent number: 7500522Abstract: Asphaltene control additives are added to base fluids which are introduced directly or indirectly into a hydrocarbon-bearing formation to mitigate asphaltene deposition in the formation which results in improved permeability in the formation and production of hydrocarbons therefrom. The fluids to which the additive is added may be liquid CO2-based, aqueous-based or non-aqueous-based fluids. Further, the fluids are fracturing fluids, drilling fluids and wellbore treatment fluids such as acidizing fluids.Type: GrantFiled: September 21, 2006Date of Patent: March 10, 2009Assignee: Innovative Chemical Technologies Canada Ltd.Inventors: Dan Skibinski, Clayton Smith

Publication number: 20090011456Abstract: Acute graft versus host disease (GvHD) is one of the most significant clinical problems in allogeneic blood and marrow transplantation. Currently, there is no unequivocal diagnostic test for GvHD until the disease is well developed and can be recognized histologically. The invention provides a blood based test for diagnosis and/or prognosis of GvHD, allowing assessment of risk for developing GvHD prior to appearance of clinical symptoms. Using flow cytometry, peripheral blood mononuclear cells are assessed for an increase in proportion and fluctuation of CD3+CD4+CD8?+ cells. An increase in presence or proportion, or high fluctuation in this cell population prior to onset of clinically recognized indicators of GvHD is predictive of later development of GvHD.Type: ApplicationFiled: March 12, 2007Publication date: January 8, 2009Applicant: BRITISH COLUMBIA CANCER AGENCY BRANCHInventors: Clayton Smith, Ryan Brinkman
