Abstract: A manually-operated dispenser for user-controlled discharge of an internally-stored fluid includes a variable length assembly normally driven to its maximum longitudinal extension for fluid-tightly closing a fluid discharge opening and a vent opening disposed at opposite ends of an elongated housing, a piston bounding an end of an internal fluid reservoir and operatively movable along the housing for volumetrically reducing the reservoir and for driving stored fluid toward and through the discharge opening, and an actuator assembly manually operable by the user for causing controlled foreshortening of the variable length assembly whereby the fluid discharge and vent openings are concurrently opened permitting the forced discharge of a correspondingly controlled volume of stored fluid.

Abstract: A system for the high speed application of pressure sensitive labels to products includes an apertured label receiving head having both some vacuum apertures or ports and also some high pressure blower apertures or ports. Connected to the vacuum ports is a main vacuum conduit and similarly connected to the high pressure blower ports is a source of high pressure air which is applied in pulses to an input high pressure air conduit. The labels are dispensed across the faceplate of the unit and are held onto the faceplate by the vacuum applied to the vacuum apertures or ports. When it is desired to apply a label to the product, a pulse of high pressure air is applied to the unit and a shuttle valve within the faceplate or immediately adjacent thereto, is actuated by the high pressure pulse of air to slide across and close off the vacuum conduit, while high pressure air is simultaneously applied to all of the blower ports to blow the label across onto the product.
