Abstract: A corrosion resistant fluid cooled acousto-optic (AO) device includes an AO interaction medium and a piezoelectric transducer affixed to the AO medium. A cooling arrangement is thermally coupled to the AO medium and includes a first material, and at least one cooling conduit in thermal contact within the first material formed from a second different material having an inlet and an outlet coupled thereto. The conduit provides a channel having an inner surface for flowing a coolant fluid therethrough, wherein the conduit includes a continuous corrosion resistant material layer over its entire area of the inner surface. The first material provides a specific acoustic impedance closer to a specific acoustic impedance of the AO medium as compared to the corrosion resistant material, and a bulk thermal conductivity at 25 C of at least 75 W/m·K.

Abstract: Disclosed in this specification is a decal assembly comprising a decal support, a releasable covercoat, a heat activatable layer, and an ink layer. The ink layer forms a digital image. The heat activatable layer has a high adhesion to a ceramic substrate at high temperatures and a low adhesion to the substrate at lower temperatures. Thus the adhesive properties of the decal are activated by heat. The resulting image has excellent adhesion to the substrate and resists the effects of washing.

Abstract: A captivated fastener assembly is provided along with a technique for captivating a fastener in a workpiece. The assembly includes a fastener having a head, a shank extending from said head that has an upper unthreaded shank portion and a lower threaded shank portion, wherein the diameter of the outer tips of the threads of the lower threaded shank portion exceed the diameter of the upper unthreaded shank portion. The assembly further includes a workpiece having a sleeve with an internal bore with a diameter slightly larger than the diameter of the fastener shank so that the sleeve can be received over the shank. The sleeve also includes segments that deform inwardly in response to a predetermined compressive force, thereby forming a plurality of deformed segments that protrude inwardly. Thus, the plurality of deformed segments provide an inner diameter that is less than the diameter of the outer tips of the threads of the lower threaded shank portion, thereby holding the fastener captive.
