Abstract: An antiseptic soap dispenser has a dispensing system (28) which includes a pressure actuated platen (32) and a moveable roller (94) for dispensing soap from a replaceable container (12). A dispensing tube (10) with an integral self-sealing valve (40) at a downstream end is connected to a neck (20) of the container. Hand pressure on the platen compresses a upstream end of the dispensing tube between the platen and the roller. With increasing pressure, the roller moves progressively down the tube to dispense soap through the valve. A volume regulator (111) controls the amount of soap dispensed. The platen returns quickly to its at-rest position once the pressure is removed, avoiding complete compression of the pathway by the roller. This minimizes air ingress, and resultant contamination of the soap. Optionally, a filtered vent (14) in a wall (22) of the container allows filtered air to enter the container in place of the soap dispensed.

Abstract: A glue head delivers lines or spots of glue onto a substrate, such as packaging materials, with precision positioning of the glue pattern, with short and balanced on/off compensation times essentially independent of glue pressure, and at high nozzle velocity. Pressurized glue advances into a plenum of the glue head preferably in a horizontal direction, then into a short and low-volume exit tube and through a nozzle, flowing in a direction perpendicular to the inflow direction. Flow to the nozzle is closed by a diaphragm valve comprising flexible elastomeric material which seats against the upstream end of the exit tube. An important feature is that glue actuator pressure is balanced, and smooth operation and glue delivery are achieved, by a rocker arm above the glue valve which, when the valve is closed by pushing the elastomeric material against the glue delivery tube, releases pressure on the glue at an upstream point in the glue plenum.
