Abstract: A paper or transparency receiving toner to be fixed by heat has an ionomeric resin on its outer surface. For universal application, the outer layer is a blend of non-ionomeric resin, such as styrene acrylate copolymer, and an ionomer, which permits the material of the toner to molecularly intermingle with the blend during heat fixing. Irradiation raises the melting point of the ionomeric resin to prevent delamination. The resulting printing is strongly bonded to the substrate and is of excellent quality.

Abstract: A valve assembly having a small volume cavity formed therein which communicates with two valves, one of which is closed completely before the other one is opened and vice versa. An actuating mechanism holds a valving member in one of the valves in an opened condition to thereby maintain a fluidic path through the one valve and the cavity. The other valving member at this time lies in a closed position preventing communication between this valve and the cavity. The actuating mechanism when actuated moves away from the valving member in the open valve allowing the open valve to close completely. The fluidic path through the one valve is thereby broken. A second fluidic path is made when the actuating mechanism moves the other valving member to an opened position.
