Patent number: 8479563Abstract: Systems and methods are provided for measuring the permeance of a material. The permeability of the material may also be derived. Systems typically provide a liquid or high concentration fluid bath on one side of a material test sample, and a gas flow across the opposing side of the material test sample. The mass flow rate of permeated fluid as a fraction of the combined mass flow rate of gas and permeated fluid is used to calculate the permeance of the material. The material test sample may be a sheet, a tube, or a solid shape. Operational test conditions may be varied, including concentration of the fluid, temperature of the fluid, strain profile of the material test sample, and differential pressure across the material test sample.Type: GrantFiled: April 3, 2012Date of Patent: July 9, 2013Assignee: Babcock & Wilcox Technical Services Y-12, LLCInventors: Russell Louis Hallman, Jr., Michael John Renner

Patent number: 7902848Abstract: A reversible test probe and test probe tip. In one embodiment, a test probe tip is reversible relative to a test probe body. The reversible probe has a first probe tip at a first end and a second probe tip at a second end. The test probe body has an opening operable to receive the first probe tip and the second probe tip. When the first probe tip is positioned in the opening, the first probe tip is electrically coupled to a metal device in the test probe body. When the second probe tip is positioned in the opening, the second probe tip is electrically coupled to a metal device in the test probe body. In another embodiment, a test probe having two test probe tips is reversible relative to a test lead.Type: GrantFiled: January 9, 2009Date of Patent: March 8, 2011Assignee: Fluke CorporationInventors: Larry Eccleston, Chris W. Lagerberg, John Renner, III, David J. Gibson, Sr.

Patent number: 5020820Abstract: A suspension system for improving the ride quality and service life of the tractor used in a tractor-trailer combination. An A-shaped sub-frame is connected at its front apex and with the tractor frame for universal pivotal movement and is rigidly connected at its back end with the rear axle of the tractor. The lift cylinders for the fifth wheel that bears the trailer weight are mounted on the arms of the sub-frame, thus applying the trailer load to the sub-frame rather than to the tractor frame. Suspension elements are interposed between the tractor axle and frame and provide the same cushioning effect regardless of whether the tractor is traveling empty or fully loaded. The universal joint mounting of the sub-frame allows tilting of the rear axle and accommodates other irregularities while avoiding undue stresses on the axle. A transverse link applies side loads from the sub-frame to the frame to avoid undue stressing of the spherical bearing that mounts the sub-frame.Type: GrantFiled: December 26, 1989Date of Patent: June 4, 1991Assignee: Capacity of Texas, Inc.Inventors: J.
