Patent number: 6376074Abstract: A debonding layer is formed on fibers such as silicon carbide fibers by forming a thin film of a metal such as nickel or iron on the silicon carbide fibers and then annealing at a temperature of about 350-550° C. to form a debond layer of a metal silicide and carbon. These fibers having the debond coating can be added to composite forming materials and the mixture treated to form a consolidated composite. A one heating-step method to form a consolidated composite involves inserting the silicon carbide fibers with just the initial metal film coating into the composite forming materials and then heating the mixture to form the debond coating in situ on the fibers and to form the consolidated composite. Preferred heating techniques include high temperature annealing, hot-pressing, or hot isostatic pressing (HIP).Type: GrantFiled: March 3, 2000Date of Patent: April 23, 2002Assignee: The United States of America as represented by the Secretary of the NavyInventors: Richard K.

Patent number: 6211526Abstract: Objects are marked for identification by a luminescent label including an optically stimulable glass having trapping centers and luminescence centers. The objects are marked by exposing the luminescent label to a radiation flux to populate metastable trapping centers in the luminescent label. The labels are read by exposing the label to a second radiation flux of optical radiation, to stimulate the release of trapped charges, causing the label to luminesce. The labels may also be read without previously populating these metastable trapping centers, by stimulating prompt luminescence through exposure to a flux of UV radiation. The label is made from an optically stimulable glass, where this glass has a glass matrix with defects, where these defects may be: (i) an alkaline earth sulfide, activator Sm ions, and an additional coactivator dopant (Eu or Ce); (ii) ZnS and activator ions (Cu, Pb, Mn, Ce, Eu, Ag, Au, or Fe); or (iii) activator ions without metal sulfides.Type: GrantFiled: September 30, 1998Date of Patent: April 3, 2001Assignee: The United States of America as represented by the Secretary of the NavyInventors: Alan L.
