Abstract: A breathing filter with a nose mask, strap(s), and a filter member. The strap(s) are elastic, and serve to hold the nose mask over the user's nose. The filter member is a plug-in device allowing removal of the filter member and replacement of the filter member cartridge or the filter material.

Abstract: A path game including a generally serpentine path rising from a start to a higher finish. Removably seated adjacent the finish is a top together with a winding and release mechanism for the top. Card play provides for forward and backward movement of tokens, exchange of tokens with opposing players and release of the spinning top. When the mechanism is removed, the top may be readily mounted on the winding and release mechanism for winding. The wound top, together with the winding and release mechanism is then reseated for release upon play of a particular type of card. Upwardly projecting ridges between segment of the path generally provide a guide for downward movement of the released spinning top along the path. Gaps in the ridges provide for movement of the top from one segment of the path to a nonconsecutive segment while skipping intervening consecutive segment and also permit the top to leave the path entirely.
