Radioisotope Based X-Ray Residual Stress Analysis Apparatus

View page
US Patent:
6353656, Mar 5, 2002
Filed:
Jul 22, 1999
Appl. No.:
09/359547
Inventors:
Francis E. LeVert - Knoxille TN
David S. Krafsur - Lenoir City TN
E. Beth Pardue - Lenoir City TN
V. Carol Bailey - Knoxville TN
Assignee:
Technology for Energy Corporation - Knoxville TN
International Classification:
G01N 2320
US Classification:
378 72, 378 70, 378 71, 378 76
Abstract:
A radioisotope based x-ray residual stress analysis apparatus having a shielded, monoenergetic radioisotopic source to emit x rays for measurement of the stress state of a polycrystalline material. The isotropic source is selected from spontaneously emissive radioisotopes emitting photons in the 5-100 keV energy range. The emissions of the source assembly are measured using either a conventional, solid-state, position sensitive detector or a gas filled position sensitive proportional counter (PSPC). In addition to normal residual stress analysis, the use of a PSPC allows the identification of characteristic photons emitted by particular isotopes to identify trace elements within a sample. As a result of the minimal shielding required for the source assembly and the small size of the isotropic source, the x-ray residual stress analysis apparatus of the present invention is uniquely suited to be configured with an area detector. Finally, the present invention is designed to be powered by commercially available dc batteries allowing residual stress analysis to be performed in remote locations, such as bridges and deserts, where power supplies are not readily available.

Fluid Flow System For Spring-Cushioned Shoe

View page
US Patent:
6665957, Dec 23, 2003
Filed:
Oct 18, 2001
Appl. No.:
09/982520
Inventors:
Francis E. Levert - Knoxville TN
David S. Krafsur - Lenoir City TN
Assignee:
Shoe Spring, Inc. - Knoxville TN
International Classification:
A43B 1328
US Classification:
36 27, 36 29, 36 53 B
Abstract:
A fluid flow system for a spring-cushioned shoe is disclosed. The sole of the shoe includes a vacuity, a spring disposed within the vacuity, and a fluid passageway in fluid communication with the vacuity. The fluid flow passageway allows fluid, such as air, to escape the vacuity when the volume of the vacuity is reduced during a foot strike.

Fluid Flow System For Spring-Cushioned Shoe

US Patent:
6865824, Mar 15, 2005
Filed:
May 14, 2003
Appl. No.:
10/436935
Inventors:
Francis E. Levert - Knoxville TN, US
David S. Krafsur - Lenoir City TN, US
International Classification:
A43B013/20
US Classification:
36 29, 36 35 B, 36 27, 36 3 B
Abstract:
A fluid flow system for a spring-cushioned shoe is disclosed. The sole of the shoe includes a vacuity, a spring disposed within the vacuity, and a fluid passageway in fluid communication with the vacuity. The fluid flow passageway allows fluid, such as air, to escape the vacuity when the volume of the vacuity is reduced during a foot strike.

Spring Cushioned Shoe

View page
US Patent:
6886274, May 3, 2005
Filed:
Feb 20, 2003
Appl. No.:
10/370638
Inventors:
David S. Krafsur - Loveland CO, US
Francis E. LeVert - Knoxville TN, US
Assignee:
Shoe Spring, Inc. - Knoxville TN
International Classification:
A43B013/28
US Classification:
36 27
Abstract:
A sole assembly for an article of footwear comprises a sole having a heel region and a ball region. A first multi-turn wave spring disposed within the sole comprises an upper turn and a lower turn. The upper turn is in pivotal contact with the lower turn to define a first side and an opposing second side of the multi-turn wave spring. Compression of the first side causes expansion pressure on the second side and compression of the second side causes expansion pressure on the first side to provide cushioning and energy return responsive to a rolling footstrike.

US Patent:
7219447, May 22, 2007
Filed:
Jan 31, 2005
Appl. No.:
11/047445
Inventors:
Francis E. LeVert - Knoxville TN, US
David S. Krafsur - Loveland CO, US
International Classification:
A43B 13/28
US Classification:
36 27
Abstract:
A sole assembly for an article of footwear comprises a midsole, a sole having a heel region, and a first wave spring disposed within a vacuity located within the heel region. The wave spring includes a top surface and a bottom surface. A plate, resting upon the top surface of the wave spring, is unsecured to the midsole and sized to permit movement within the vacuity along with the wave spring responsive to a rolling footstrike.
