Patent number: 6530965Abstract: A method for enabling the use of heavy oil residuum by conversion to a useful product. The method, in one embodiment, involves the use of a heavy oil residuum which is substantially non flowable. The viscosity of the residuum is reduced and subsequently mixed with water such that the mixing is high shear mixing. This results in the formation of an emulsion of predispersed residuum in an aqueous matrix. The emulsion is formed such that the aqueous matrix is in a size distribution suitable for use as a combustible fuel.Type: GrantFiled: April 27, 2001Date of Patent: March 11, 2003Assignee: Colt Engineering CorporationInventor: Edward J. Warchol

Patent number: 6475458Abstract: There is disclosed a method for formulating food grade sodium bicarbonate by purification of a sodium bicarbonate liquor where an initial saturated feedstock of sodium bicarbonate which contains sodium sulfate as an impurity is filtered to remove the impurities and a first filtrate liquor formed. The filtrate liquor is then subjected to ion exchange with a cationic resin to reduce the calcium and magnesium ion concentration present in the filtrate liquor with subsequent cooling of the liquor. The cooled liquor is also treated with a source of ammonia or ammonium ions to shift the solubility of the compounds to retain sodium sulfate in solution while precipitating sodium bicarbonate with reduced sulfate occlusions. The precipitated sodium bicarbonate is then filtered to result in a food grade sodium bicarbonate product.Type: GrantFiled: October 25, 1999Date of Patent: November 5, 2002Assignee: Airborne Industrial Minerals Inc.Inventor: Robin Phinney

Patent number: 6454979Abstract: A method of wet granulation of fertilizer and other materials into granules. The method involves formation of the granule directly on the pan from the feedstock without intermediate steps or the use of seed materials. The result is a product having a completely uniform cross section. The feedstock is initially in the size distribution of −150 mesh with 90% or greater in the size range of 200 mesh. Moisture is maintained to facilitate a steady process without cycling.Type: GrantFiled: April 17, 1998Date of Patent: September 24, 2002Assignee: Airborne Industrial Minerals Inc.Inventor: Robin Phinney

Patent number: 5807415Abstract: A transformable and collapsible filter frame which can support various air intake filtering media for internal combustion engines. One form of the filter frame corresponds generally to the shape of a carousel. The frame facilitates replacement of reusable filtering medium to be applied over its surface. The filtering media may be a polyurethane foam. The carousel filter frame structure includes expandable and adjustable parts, rings and struts which, when integrated are used as supporting members. The rings and struts include connecting members and can be easily disassembled and reassembled. The carousel filter body structure can be easily transformed into various configurations and sizes with the adaptable filter frame parts as desired to form other different types of filter shapes or forms. One shape of the carousel can be split to form various shapes of filter frames such as a circle, cylinder, shield, cone, oval, square, rectangle and various combinations thereof.Type: GrantFiled: November 29, 1995Date of Patent: September 15, 1998Inventor: Ano Leo

Patent number: 5795064Abstract: A method of measuring thermal conductivity of a sample in both a machine direction and a transverse direction. The method is carried out with a probe having a electroconductive member in each of the above-mentioned directions. Upon application of a current to the probe, fluctuations in the voltage are received as a result of contact with the sample. This information is then used to generate a thermal conductivity ratio.Type: GrantFiled: September 29, 1995Date of Patent: August 18, 1998Assignee: Mathis Instruments Ltd.Inventor: Nancy Mathis

Patent number: 5759665Abstract: An insulating spacer for use in glazing assemblies is provided. The spacer comprises a foamed insulating body and further includes a second sealant material. The insulating body partially contacts the substrates as does the sealant to provide a double seal when used in a glazing assembly. In other embodiments the spacer is a composite of foam, sealant material, rigid plastics and desiccated matrices. A further embodiment discloses an undulating foam spacer body for easy manipulation about the corner in glazing assemblies. The result of incorporation of the foam is a substantially energy efficient spacer and assembly.Type: GrantFiled: December 6, 1995Date of Patent: June 2, 1998Inventor: Luc Lafond

Patent number: 5732476Abstract: The generation of volatiles from liquid or solid materials is enhanced and accelerated by exposure to microwave radiation. Normally the energy transfer is effected preferentially toward the liquid or solid materials over the generated gaseous volatiles. Sufficient energy is provided at a selected rate that enhances the generation of volatiles to effect removal as vapor or to produce a pressurized vapor phase. Flow-through separations from a matrix having a microwave-absorbing liquid component are conducted by exposing to microwave radiation to vaporize this component and processing the vapor either by flowing through a selective permeable membrane, or by enclosing the vapor and matrix in a confined space and flowing matrix through a selected separation medium, and recovering residual matrix. These separations are particularly useful in analysis contexts.Type: GrantFiled: May 24, 1996Date of Patent: March 31, 1998Inventor: J.R. Jocelyn Pare

Patent number: 5663649Abstract: A soil penetrometer and method of using this apparatus are disclosed. The method relates to the application of a constant force to a soil penetrometer, the penetrometer capable of detecting soil moisture content by time domain reflectrometry. The use of the constant force eliminates the variable nature of this parameter conventionally encountered in the art, and therefore reduces the complexity of soil parameter calculation.Type: GrantFiled: June 2, 1995Date of Patent: September 2, 1997Assignee: Her Majesty The Queen in right of Canada, as represented by Agriculture and Agri-Food CanadaInventors: Clarke Topp, Bruce Compton, Keith Wires

Patent number: 5635019Abstract: There is disclosed a strip applying tool for applying strip material to substrates. The tool includes a slidably mounted punching member to remove a portion of the strip material thereby facilitating the formation of a corner while maintaining the strip in a continuous uninterrupted length. The tool further provides a channel extending therein to receive strip material which provides a guide wall to permit the application of the strip to the substrate while maintaining a lower surface of the tool above the substrate to prevent moving or scratching of the substrate.Type: GrantFiled: June 7, 1995Date of Patent: June 3, 1997Inventor: Luc Lafond

Patent number: 5633494Abstract: A curvature or bending and displacement sensor is composed of a fiber optic or light wave guide, for attachment to a member or members being curved or displaced. Light is injected at one end and detected at the other end. Curvature of the fiber results in light loss through an emission surface or surfaces, sometimes in conjunction with a superimposed curvature in a plane other than that of the curvature to be measured, this loss being detected. The loss of light detection is used to produce indication of curvature or displacement. The light emission surfaces extend in various forms, such as a surface strip or band. Particularly, in an example, the emission surfaces extend in a substantially peripheral direction, or in a substantially curved axial direction when in a curved portion of a curved guide. The placement, shape and configuration of the emission surfaces allows adjustment of the linear range of measurement, the overall throughput of light, and the length over which curvature is measured.Type: GrantFiled: September 22, 1995Date of Patent: May 27, 1997Inventor: Lee Danisch
