Title: Radial-flow fluidizable filter.
Inventor: JOHN D MARTIN
IPC: B01D35/153
Filed: 1997-05-23
Abstract: A radial-flow filter (120) employing nonbonded granular particles (56) for filtering impurities from an influent, and that can be backwashed by fluidizing the granular particles (56) to free the impurities therefrom. During a backwashing operation, a backwash liquid applies an upwardly-directed drag force on an upper portion of the granular particles (56) to lift the same into a backwash chamber (62) for fluidization. Once the top portion of the granular particles (56) of the filtration bed is fluidized, the backwash liquid applies an upward force on a subsequent portion of the granular bed, thereby fluidizing the granular particles (56) in the backwash chamber (62). Subsequent sections of the granular bed are fluidized in a similar manner to thereby completely clean the granular particles (56). After the backwash operation, the granular particles (56) fall back to the filtration chamber (156) and form a filter bed for carrying out a filtration operation.

IPC: B65D77/04
Filed: 1988-08-17
Abstract: A protective safety container (10) for encasing toxic drug filled glass vials (18) is disclosed. The container includes a molded plastic body (12) that is shaped to conform to the shape of a vial to be protected. A plurality of spaced longitudinal ribs (32) are formed on the inner surface of the container body (12) that act to engage the vial (18) and hold it firmly in position, and also form a cushioning air space between the vial and the container. A molded plastic annular base (14) is adapted to be snap fitted into the body (12) such that the vial (18) cannot be easily removed once it is secured within the container. Disposed in the top (15) of the container is a small aperture (26) having a frangible disk (28) disposed therein. The disk (28) may be removed so that a hypodermic needle may be inserted into a stopper (19) in the vial (18) to withdraw the vial's contents. The aperture (26) is too small, however, to permit removal of the stopper itself. All of these features combine to provide a protective container for a glass vial which will prevent the intentional or accidental discharge of the vial's contents to the surrounding area.
