Abstract: High temperature ceramic nut of aluminum oxide for use in coupling a flared tube to a flare fitting.

Abstract: The invention relates to a process for producing a riveted joint using a riveting tool. The essential feature is that a pin-shaped blank of a recrystallized, coarse-grained iron-based or nickel-based ODS superalloy having a grain elongation in the longitudinal direction of 5:1 to 50:1 is used for the rivets. The production of the rivet heads is performed under defined process temperatures, at a pin temperature between 600.degree. and 1000.degree. C. and at a tool temperature between 50.degree. and 300.degree. C.

Abstract: An anchor pin, for anchoring one component upon another, such as an electrical connector upon a printed circuit board, by way of a passage defined by a mounting hole in one of the components that is substantially aligned with an opening in the other component. The anchor pin having a first form with a volume larger than the volume defined by the passage while being receivable within the passage and a second form in response to an external energy input, whereby the anchor pin within the passage becomes fluid deforming to substantially fill the passage, automatically accommodating any misalignment, and overflowing therefrom to form opposing heads. The mounting pin hardens in this form to anchor the components together.
