Abstract: A molten plastic delivery system is disclosed having a nozzle defining a nozzle channel with a downstream nozzle channel opening. A valve pin is reciprocable within the nozzle channel between a closed position and an open position. The system includes a bell crank having first and second arms that are connected at and rotatable about a pivot. The first arm is coupled to the valve pin and the second arm is coupled to a push-pull cable such that angularly pushing the second arm about the pivot via the push-pull cable moves the valve pin to the open position and angularly pulling the second arm about the pivot via the push-pull cable moves the valve pin to the closed position.

Abstract: A greeting card is disclosed which has a self-inflating balloon contained therein, which balloon inflates either upon opening the greeting card, upon removing the greeting card from an envelope, or upon manual activation by the individual receiving the greeting card. A gas generator is provided with two reactants which are separated by a physical barrier until the device is activated, at which time the reactants mix to generate gas used to inflate the balloon. In the preferred embodiment, the physical barrier is a zipper-like fastener element which is pulled apart by a triggering mechanism to activate the gas generator to inflate the balloon.

Abstract: An expandable baseball hat and cover adapted to expand and conform to differently shaped heads or protective devices. The hat includes a first flexible material which has an inner surface, an outer surface and a peripheral edge to form a skirt portion. The inner surface of the first material is provided with two tab members, each of which has coacting fastening means for releasable engagement with each other. The tab elements are engaged to gather the flexible material for a snug, conformed fit to the wearer's head. The expandable hat can be used in combination with a rigid shell, such as a batting helmet. The expandable hat is fitted over the shell for the skirt to snugly engage the peripheral edge of the shell without other fastening means. The skirt and inner surface of the shell are provided with second coacting fastening means in registration for releasable engagement.
