Abstract: A nozzle assembly (24) for filling a container with a homogeneous mixture of viscous liquids includes a housing (28) having an inner passageway (40) extending therethrough defining a longitudinal axis (42) of the housing (28) and an axially rotatable drive shaft (44) supported by the housing (28) and extending through the passageway (40) along the longitudinal axis (42). A folding mechanism includes stationary pins and moving pins mounted tangentially relative to a centrally disposed drive shaft (44) disposed along the longitudinal axis (42) for folding the liquids flowing through the passageway (40) while preventing columns of unmixed liquid from flowing axially along the drive shaft (44).

Abstract: A valve comprising a cylinder with a number of inlet and outlet ports at one end having movable therein a resiliently surfaced piston, wherein the valve is closed by movement of the piston to a position wherein the resilient surface simultaneously closes all of the ports. Means is provided to normally urge the valve toward an open position and closing means which may be highly pressurized air is provided to move the piston to a valve closed position.
