Abstract: A method of extending the useable life of a gas turbine component fabricated from a cobalt-based alloy is disclosed. The method includes applying a rejuvenation process to the alloy where the alloy is placed in a protected atmosphere and heated to three different elevated temperatures and held at the elevated temperatures for approximately four hours each. Application of the rejuvenation process allows gas turbine components to be returned to service for at least one more service interval of approximately 24,000 operating hours.

Abstract: A method of personal locomotion including stepping onto first and second wheeled shoe accessories and engaging the first wheeled shoe accessory against a support surface to roll on the second wheeled shoe accessory in a desired direction at an angle to a normal walking direction. The wheeled shoe accessory includes a rigid board having a length sufficient to span a width of a shoe placed sideways across the board, with the board supporting at least an arch region of the shoe. At least one axle assembly is secured to a lower surface of the board. The user experience is similar to that of a skateboard, but with decoupled feet for individual maneuverability of each wheeled shoe accessory.

Abstract: A wheeled shoe accessory specifically adapted for rolling in a direction other than a direction in which the user's shoes are oriented. The wheeled shoe accessory includes a rigid board having a length sufficient to span a width of a shoe placed sideways across the board, with the board supporting an arch region of the shoe. At least one axle assembly is secured to a lower surface of the board. The axle assembly includes an axle and at least one roller rotatably mounted on the axle. At least one releasable fastener is joined to the board and configured to secure the board to the shoe sole. The user experience is similar to that of a skateboard, but with decoupled feet for individual maneuverability of each wheeled shoe accessory.
