Abstract: A cloud tower (11) receives microscopic particles (18) impelled by an inert gas (17) for deposition on a porous substrate (29) having vacuum (34) disposed on opposite side. To alter the size and/or shape of the deposition field without changing the entire tower structure, a pair of flaps (43, 44) are hinged (47, 48) on one side or on a pair of opposed sides of the cloud primary tower. Another embodiment places selectable tower inserts (36, 38) within the primary tower structure, fitting therein and sealing thereto.

Abstract: A quickly releasable vest capable of protecting a torso portion of a user is disclosed. The quickly releasable vest includes a self locking buckle assembly, a ferrule, an elongated strip, and a socket member. The self locking buckle assembly comprises a wedge fork with a base portion and a body portion, the base portion comprising a security means for webbing and the body portion comprising a pair of legs and a ferrule guide member. The ferrule is adapted to be slidingly disposed on the ferrule guide member. A proximal end portion of the strip is connected to a tape guide member of the ferrule. An opening on the socket member facilitates removably retaining and locking of a prong on each of the pair of legs. The wedge fork, ferrule, and elongated strip Is disposed on a torso panel and the socket member is disposed on the other torso panel.
