Patent number: 5988198Abstract: A process for transporting deaerated bitumen froth in a pipeline is described which comprises injecting water into the pipeline prior to deaerated bitumen froth injection to wet the interior walls of the pipeline. The deaerated bitumen froth is then injected into the pipeline at a critical velocity above 0.3 m/sec thereby initiating self-lubricating core-annular flow of the bitumen froth.Type: GrantFiled: November 12, 1998Date of Patent: November 23, 1999Assignees: AEC Oil Sands, L.P., AEC Oil Sands Limited Partnership, Athabasca Oil Sands Investments Inc., Canadian Occidental Petroleum Ltd., Canadian Oil Sands Investments Inc., Gulf Canada Resources Limited, Imperial Oil Resources, Mocal Energy Limited, Murphy Oil Company Ltd., Petro-CanadaInventors: Owen Neiman, Ken Sury, Daniel D.

Patent number: 5646352Abstract: The present invention comprises method of measuring a parameter of a multiphase flow of a fluid and apparatus therefore. The apparatus comprises a buffer chamber apparatus that is operably fluidly coupled to a pipe bearing a fluid comprised of components of different densities. The buffer chamber apparatus has structure that defines a substantially fluid tight chamber that is in flow communication with the fluid borne in the pipe. One or more ports are defined in the chamber structure whereby the fluid in the chamber may be selectively accessed for sensing a parameter of the fluid. The fluid in the chamber resides in a substantially stable state promoting the separation of the different density components of the fluid.Type: GrantFiled: December 11, 1995Date of Patent: July 8, 1997Inventors: Daniel D. Joseph, Runyuan Bai

Patent number: 5301541Abstract: An apparatus and method for determining the effect of the configuration of an outer surface of an object on the drag of the object. The apparatus comprises a housing, an inner block suspended in the housing, a motor for rotating the housing, and a torquemeter. The inner block is connected to the torquemeter by a suspending rod and universal joint. The method comprises attaching a layer of material having a desired surface configuration to the inner block and to the housing, filling the housing with a fluid, and driving the motor so that the housing is rotated. The magnitude of the torque on the inner block is then measured by the torquemeter. The rate of rotation of the housing and the temperature of the water are monitored.Type: GrantFiled: June 19, 1992Date of Patent: April 12, 1994Inventors: Daniel D. Joseph, Francis J.

Patent number: 5150607Abstract: A spinning drop tensioextensiometer provides for the ability to rotate a tube carrying two different polymers, under conditions which keeps the polymers melted, and which causes the less dense polymer to form a drop of a generally cigar shape. By measuring the diameter of the drop at desired angular velocities upper and lower bounds for interfacial tension can be determined. Further, these bounds define relaxation curves for the extensional relaxation of a blend of two polymers. The polymers are placed in a glass tube that is rotated at high speed within an oven that has an opening through which the diameter of the inner polymer drop can be measured utilizing optical equipment, such as a video camera projecting an image onto a monitor.Type: GrantFiled: August 8, 1991Date of Patent: September 29, 1992Assignee: Daniel D.

Patent number: 4644782Abstract: A transparent cylinder is filled with two liquids of different densities and is sealed at both ends. A rod, having a diameter smaller than the inner diameter of the cylinder is mounted on the longitudinal axis of the cylinder. The filled cylinder is mounted horizontally between two end supports and rotated about the longitudinal axis of the cylinder. The less dense liquid will form around the rod at an appropriate speed, and when steady state equilibrium is achieved by the liquids inside the cylinder, the diameter of the less dense liquid and the rotational speed of the cylinders are measured.Type: GrantFiled: February 13, 1986Date of Patent: February 24, 1987Assignee: Regents of the University of MinnesotaInventor: Daniel D.

Patent number: 4602502Abstract: A wave speed meter comprises a pair of relatively rotatable, concentric cylinders with a gap between the cylinders to define a chamber. A viscoelastic fluid is placed in the chamber, and one of the cylinders is suddenly rotationally displaced causing a shear induced wave to be propagated through the fluid filling the chamber between the cylinders. This wave is propagated toward the other cylinder and when the wave reaches the other cylinder the other cylinder moves. The transit time of the wave is determined by measuring the time between the displacement of the one cylinder and movement of the other cylinder as a result of the wave. The distance that the wave travels is known, so that the wave speed can be determined.Type: GrantFiled: January 22, 1985Date of Patent: July 29, 1986Assignee: Regents of the University of MinnesotaInventors: Daniel D. Joseph, Oliver Riccius
