Patent number: 11938045Abstract: Breathable residual-limb system that admits air and allows sweat to evaporate from the surface of the residual limb. In an embodiment, the system comprises a liner sock to be worn on the residual limb, and comprising air-permeable textile forming a substantially cylindrical portion that is closed on a distal end and open on a proximal end and comprising an internal surface and an external surface. The liner sock further comprises a friction-interface material that covers only a portion of the internal surface of the air-permeable textile, such that, when worn on the residual limb, the friction-interface material contacts a surface of the residual limb, and an uncovered portion of the air-permeable textile which the friction-interface material does not cover allows air to pass between an external environment of the liner sock and the surface of the residual limb.Type: GrantFiled: November 23, 2022Date of Patent: March 26, 2024Assignees: United States Government As Represented By The Department Of Veterans Affairs, Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.

Patent number: 9587747Abstract: Flexible seals for process control valves are disclosed. An example disclosed seal includes a seal for use with a butterfly valve. The example seal includes a substantially flexible ring-shaped carrier configured to be moveably fixed within the butterfly valve and to surround a flow control aperture therein. The example seal includes a seal stiffener adjacent the substantially flexible ring-shaped carrier to increase the stiffness of the substantially flexible ring-shaped carrier in a first flow direction. The example seal includes a substantially rigid seal ring to engage an opposing surface.Type: GrantFiled: September 1, 2015Date of Patent: March 7, 2017Assignee: FISHER CONTROLS INTERNATIONAL LLCInventors: Wade Jonathon Helfer, David John Koester, Benjamin Uriah Good, Paul Russell Dalluge, Andrew John Olson

Publication number: 20160238149Abstract: Fluid valve apparatus having enclosed seals are disclosed. An example apparatus includes a seal having an inner core composed of a first material and an outer sheath composed of a second material different than the first material, a carrier having a first portion and a second portion extending from the first portion. The first portion couples to the seal. The second portion clamps between a retainer and a valve body of a fluid valve to couple the seal to the valve body. A first surface of the second portion engages the retainer and a second surface of the second portion opposite the first surface engages the valve body when the second portion of the carrier is clamped between the retainer and the valve body.Type: ApplicationFiled: April 26, 2016Publication date: August 18, 2016Inventor: David John Koester

Patent number: 9400061Abstract: Fluid valve apparatus having enclosed seals are disclosed. An example fluid valve includes a movable flow control member positioned between an inlet and an outlet of a fluid flow passageway of the fluid valve. A retainer is removably coupled to the flow control member such that the retainer and the flow control member define a sealing cavity when the retainer is coupled to the flow control member. A seal is positioned within the sealing cavity to define a sealing surface of the flow control member. The seal has an inner core composed of a first material, where the core is substantially encased with a sheath composed of a second material different than the first material. The retainer clamps the seal to the flow control member.Type: GrantFiled: July 29, 2013Date of Patent: July 26, 2016Assignee: FISHER CONTROLS INTERNATIONAL LLCInventor: David John Koester

Patent number: 8782360Abstract: A method, system and computer-program product for re-initializing a storage volume with an previously created volume map being preserved to allow access to previously stored data sets. The invention includes creating a new volume map in an unused volume area where the new volume map has pointers to new data sets. One of the new data sets contains the previously created volume map that points to previously created data sets. Each volume map is referenced by a volume label and includes a VTOC and an optional VTOC index. The pointers in the VTOC are data set control block (DSCB) records.Type: GrantFiled: May 13, 2010Date of Patent: July 15, 2014Assignee: International Business Machines CorporationInventors: James B.
