Abstract: An apparatus for applying granules onto an asphalt-coated sheet includes a granule applicator positioned above an asphalt-coated sheet moving in a machine direction. The granule applicator deposits granules into contact with the asphalt-coated sheet along a contact line substantially perpendicular to the machine direction, thereby defining a granule-coated sheet. A granule deflector plate engages the granule-coated sheet downstream of the contact line such that the granule deflector plate rides on the granules of the granule-coated sheet.

Abstract: Methods and apparatus for testing a microscale or nanoscale sample. A testing stage comprises a frame having first and second laterally opposing ends and first and second side beams. At least one deformable force sensor beam is disposed near the first opposing end and extends laterally between the first and second side beams. A first longitudinal beam, having a free end, bisects the at least one force sensor beam, and a second longitudinal beam has a free end facing the free end of the first longitudinal beam to define a gap therebetween. A support structure comprises a plurality of laterally extending beams disposed such that the second longitudinal beam bisects the plurality of laterally extending beams. Each of a pair of slots disposed at each of the free ends of the first and second longitudinal beams comprises a tapered portion leading to a generally longitudinal portion aligned with the central longitudinal beam. The slots provide a seat for a dogbone-shaped sample.

Abstract: Fiber-reinforced ceramic honeycomb is prepared by impregnating a high-temperature fiber, notably fibers of ceramic materials such as silicates, aluminosilicates, aluminates and silicon carbides, with a liquid solution or suspension of a ceramic precursor material, followed by forming the impreganted fiber into corrugated strips, assembling the strips into the honeycomb structure, then heating the strips to form the ceramic. Multiple impregnations with intervening heating are useful in controlling the density and quality of the product.
