    Abstract: A pressure tap probe having a flexible probe tip that is flexible enough to seal a film cooling hole having a roughened surface such as a TBC applied around the hole. The flexible probe tip is flexible enough to deform around the film cooling hole such that an accurate pressure reading can be observed for the film cooling hole. The flexible pressure tap is used to measure the pressure at a plurality of film cooling holes on a turbine airfoil when a pressure and a flow rate of cooling air is passed through the airfoil. A plurality of film cooling holes are measured by using the flexible pressure tap to determine if the cooling passages and film cooling holes are properly sized to provide adequate cooling for the airfoil.

    Abstract translation: 一种压力分接头探头，其具有柔性足够的挠性探针头，以密封具有粗糙表面的薄膜冷却孔，例如施加在孔附近的TBC。 灵活的探针尖端足够柔韧，能够在薄膜冷却孔周围变形，从而可以观察到薄膜冷却孔的准确的压力读数。 当冷却空气的压力和流量通过翼型时，柔性压力分接头用于测量涡轮机翼型上的多个薄膜冷却孔处的压力。 通过使用柔性压力分接头来测量多个薄膜冷却孔，以确定冷却通道和薄膜冷却孔的尺寸是否合适，为翼型件提供足够的冷却。

    Abstract: The present invention includes a flexible device incorporating a magnet, and the method of manufacturing the device, wherein said device is used for holding an exercise towel against the metallic surfaces of fitness machines to promote the hygienic use of fitness towels. The device comprises an elongate strap having opposed and first and second end portions. An opening is provided in the first end portion for receiving a towel and a magnet is embedded within the second end portion for attaching the metallic surface of fitness machine. The invention includes a method for producing the device by using an open mold elongate cavity with a post attached to the base of the cavity of a first end of the elongate cavity for forming the opening in the device, and a metal post formed into the base of the second end of the cavity, the steps including: placing a magnet into the cavity at the second end, and positioning said magnet in proper location and orientation onto the top of said metallic post; filling said cavity with a liquid to cover the magnet in the second cavity end; and solidifying the liquid into a flexible material to form the device.
