Abstract: An eyeglass assembly includes a frame having first and second lens openings. A lens is dimensioned for receipt in the lens opening. The lens has a key selectively interconnecting the lens to frame in a lens opening. The key has a protrusion received in a complementary groove in the frame around the lens opening, and a tab along a minor portion of the key that is received in a notch in the frame groove which provide a region where less force is required to mount or remove the lens relative to the frame.

Abstract: One embodiment of the invention is a hand-held fire extinguisher including: a tube having an open outlet end, an outer surface, and an inner surface; a fire suppressant composition provided within the tube; a propellant source containing a propellant, having a propellant outlet, where the propellant outlet is distal from the open outlet end of the tube and from the fire suppressant composition, and where the propellant outlet is in fluid communication with the fire suppressant composition and the open outlet end of the tube; and an actuator for the propellant source. In such apparatus, actuation of the actuator allows propellant flow from the propellant outlet passing through the fire suppressant composition and out through the open outlet end of the tube.
