Abstract: A flexible bearing is constructed of layers of elastomer and rigid shims, alternately stacked and bonded together. At least some of the rigid shims are replaced with flexible reinforcements of refractory cloth or wire screen. The reinforcing material minimizes the number of rigid shims required. In some applications, the rigid shims may be completely eliminated.

Abstract: A thrust nozzle for a rocket has an improved exit cone made of a strong, refractory material with tufts of high temperature fibers anchored in it to form a pile, in the manner of a carpet. The pile is on the inside of the nozzle, so that propulsive gases of the rocket may impinge directly thereon. The exit cone may be either rigid, as is conventional, or foldable so that the rocket may be stored in a minimal space. The folded exit cone may be extended by any of various actuating systems when the rocket is launched. This pile construction may also be used for other surfaces that must be exposed to hot, high velocity gases.
