Abstract: A system and method for infrared (IR) thermography examination of a specimen under test are disclosed. One such method comprises one of imparting heat energy to the specimen under test with a heat energy source or removing heat energy from the specimen under test with a heat sink. Respectively, one of the heat energy source or the heat sink is removed. Using IR images, areas of surface heat transfer discontinuity of a surface temperature distribution of the specimen under test are identified to determine a distribution of a filler material in a base material of the specimen under test.

Abstract: The present disclosure relates to passively rotating a valve using fluid flow. Some aspects may involve a valve including a body, a lower stem, and vanes. The body may include a bottom portion that can be positioned with respect to a seat for preventing fluid flow when the valve is in a closed position. The lower stem may extend axially from the bottom portion of the body to position the bottom portion with respect to the seat. The vanes may extend from the body and be responsive to the fluid flow while the valve is in an open position such that the valve and the lower stem rotate with respect to the seat.

Abstract translation: 本公开涉及使用流体流动被动地旋转阀门。 一些方面可能涉及包括主体，下部杆和叶片的阀。 该主体可以包括底部，该底部可以相对于座位定位，以在阀处于关闭位置时防止流体流动。 下杆可以从本体的底部轴向延伸以相对于座位定位底部。 叶片可以从本体延伸并且在阀处于打开位置时响应流体流动，使得阀和下阀杆相对于座椅旋转。
