  • Stress assisted cutting of high temperature embrittled materials
    Patent number: 4562333
    Abstract: A method of severing an article subject to hot short phenomena is taught. A seam of the article is heated to bring it to the hot short condition and to have the remainder of the article at a temperature outside of the hot short range. A force is then applied to the seam to cause the article to sever due to brittleness of the material of the seam.

  • Surface acoustic wave device from eutectic deposit
    Patent number: 4527082
    Abstract: A method for the fabrication of surface acoustic wave devices by the selective removal of one of the phases of a metallic eutectic, solidified as a thin film having a lamellar morphology, forms a first spaced array of metallic elements. Removal is by line-heater or laser beam. This then provides a self-aligned structure for the formation of a second array of metallic elements interdigitated with the elements of the first array.

  • Method and apparatus for reconstruction of three-dimensional surfaces from interference fringes
    Patent number: 4525858
    Abstract: A fully automatic method for rapidly and unambiguously interpreting fringe patterns, including those having branched fringes, is provided. The information from the fringe patterns processed by the method of the invention can be used in testing, surface characterization and inspection applications. Further processing of the information from the two-dimensional fringe patterns yields information from which the three-dimensional surface can be quantitatively reconstructed for further use such as for display, as in microscopy, or as input for computer-aided design and computer-aided manufacture. Apparatus for conducting the method of the invention is also provided.
