Abstract: A pour spout is provided for dispensing liquid from a fluid carrying vessel such as a liquor bottle. The pour spout includes an insertable member configured to engage an internal surface of the bottle neck and form a liquid tight seal therewith. An external spout extends from the insertable member for directing the flow of liquid out of the vessel. Within the pour spout, an internal flow channel extends through both the insertable member and the external spout, the flow channel forming a nozzle aperture at the end of the external spout allowing liquid contained within the vessel to flow through the spout. Finally, a sealable cap is operably attached to the external spout. The cap may be operated between an open and a closed position, wherein in the open position, liquid can flow through the cap, and in the closed position, an air tight seal is formed over the end of the spout.

Abstract: A radio frequency identification transponder (RFID tag) includes an RFID antenna and one or more elements of nonlinear magnetic material tuned to resonate at substantially the same frequency as the resonant frequency of the tag antenna. This co-resonance amplifies signals that impinge upon the antenna, yielding both a higher level signal from the antenna to the tag electronics and wider operational bandwidth for the tag. With the addition of the nonlinear magnetic material, the tag may also be employed as a magnetic surveillance tag, with the attendant non-screening capabilities. With a plurality of nonlinear magnetic elements tuned to different resonant frequencies, the tag may provide more "non-screenable" information, that is, two bits, or four binary states, for example, when two such elements are employed.

Abstract: Liquid crystal cells operable between wide temperature ranges (below 0.degree. C up to 84.degree. C) are provided. These cells include mixtures of compounds from the series ##STR1## WITH A COMPOUND FROM THE SERIES ##STR2## wherein n is an integer from 1 to 7 and m is an integer from 1 to 4.
