Abstract: An air-treating apparatus for dispensing a volatilizable material, such as air freshener fragrance, into the atmosphere of an enclosed area. The apparatus includes a housing and a reservoir of the volatilizable material therein, and also includes a multiple-configured air flow path arrangement which enables air-flow through the apparatus in multiple configurations. The apparatus enables use of the consistent delivery rates of a volatilizable material producing a more consistent delivery rate than normally achieved with such devices.

Abstract: A method of selectively controlling the threaded disposition of a threaded element having a portion defining a flat side relative to a member having a complementary threaded means, the flat side of the element extending parallel to the axis of the threaded element and being disposed adjacent the member and a tool for use in concurrently rotating a threaded securing element having a flat-sided portion and deflecting away from the element a turned tab of a locking element disposed in the space adjacent one flat side of the element provided to lock the element against rotation. The tool defines a socket having an open portion. The edges of the open portion define tab deflectors.
