Abstract: A nozzle is provided which includes a nozzle body having a proximal end and an insertion end and defining an inlet orifice at the proximal end thereof and an outlet orifice at the insertion end thereof. The nozzle body is adapted to be attached at the proximal end thereof to an opening of a container and to be inserted at the insertion end thereof into an opening of a receiving vessel for dispensing a first fluid from the container into the receiving vessel from the inlet orifice to the outlet orifice thereof. The nozzle further includes a venting device connected to the nozzle body and defining a vent discharge opening for venting a second fluid from the receiving vessel into the container through the vent discharge opening such that the second fluid is vented through the vent discharge opening of the venting device without traversing the first fluid in the container substantially during an entire time for a dispensing of the first fluid from the container into the receiving vessel.

Abstract: An inhomogeneous, optically active medium with optically active components, such as, an ink with reflective flakes or a gemstone dust, is included on or embedded in one or more portions of a workpiece. When the portions are illuminated with visible and/or ultraviolet light, the components, which are also anisotropic, provide readily detectable information that can be extracted for a string which is included on or associated with an indicium that is used to authenticate the workpiece. To verify the workpiece, the one or more portions that contain the optically active medium are again illuminated, and the string is then newly generated from various images of the appearances of the components. The newly generated string or, as appropriate, an indicium that is based on the string is then compared with a string or an indicium that is imprinted on or associated with the workpiece. If the previously and newly generated strings or indicium correspond, the workpiece is determined to be authentic.
