Abstract: This invention relates to the creation of a swifter, cleaner, way of moistening envelope flaps to seal them. It represents an improvement over other designs of systems using nozzles in that it adjust for a variety of envelope flap shapes and lengths and depths. It is also an improvement over sponge or wick systems, since no glue build up is created. With a push of a button, a spray of water or sealing fluid, is directed to the flap, after symmetric geared adjustable arms, each arm geared at a pivot between them, are positioned (including a valve on each arm to adjust for a smaller envelope flap). After the envelope is positioned and the button is pushed, a spray of fluid falls upon the flap, directed downward by a number of nozzles on each arm, all connected to the pump and fluid reservoir by flexible tubes and conduits. The spring button returns to position, while drawing fluid up into the small piston pump to be used for another envelope.

Abstract: An attachment for an air filter enabling it to be worn at a convenient location on a person's clothing. The attachment has a fitting for attachment to the filter which provides a passageway for the filtered air, a hose having a main air passage extending up from the fitting to a breathing device and a branch passage between the breathing device and ambient air, and a check valve arrangement which closes the branch passage when the user is drawing in filtered air and opens the branch passage when the user expels air through the breathing device. The fitting has a safety pin for attaching it and the air filter to the user's clothing.

Abstract: A pellet dispenser comprising an elongated tube for holding pellets end-to-end and a pellet restraining device on the tube. This restraining device comprises (1) a casing straddling the tube near one end; (2) a push-button; (3) a generally U-shaped body extending down from the push button and straddling the tube; (4) a spring biasing the push button and the U-shaped body to a position in which the bottom of the "U" is just beneath the tube; (5) a rigid first stop member extending from the U-shaped body up into tube to engage the front of the first pellet in the tube except when the push button is depressed; and (6) a second stop member with a soft, deformable bottom piece extending from the push button down into the tube to engage the next pellet directly behind the first pellet when the push button is depressed.
