Abstract: The present invention contemplates methods of bonding devices that produce sonic energy to polymer articles, the bonded articles themselves, methods for fabricating a semiconductor processing apparatus, and the apparatus itself. The present invention provides for an apparatus comprised of polymers, which is not susceptible to corrosion and permit the transmission of sonic energy through the walls of the apparatus. The polymer can be, for example, a fluoropolymer.

Abstract: A storm protection system for openings such as windows which include an upper housing, mountable on the upper or lower, in some applications, edge of the window, the housing accommodating a reinforced fabric shade being substantially the width of the window, on a roller within the housing so that the shade may be pulled from a first storage position within the housing to a second down position so that it would completely cover the window opening. There is further provided a plurality of spaced apart pockets formed within the fabric shade, and extending along its entire length, each of the pockets accommodating a length of a tubular member such as a section of PVC pipe, which would slidably engage within the pockets to form a plurality of reinforced members along the length of the shade as the shade is pulled downward.
