Abstract: Shaped glasses have curved surface lenses with spectrally complementary filters disposed thereon. The filters curved surface lenses are configured to compensate for wavelength shifts occurring due to viewing angles and other sources. Complementary images are projected for viewing through projection filters having passbands that pre-shift to compensate for subsequent wavelength shifts. At least one filter may have more than 3 primary passbands. For example, two filters include a first filter having passbands of low blue, high blue, low green, high green, and red, and a second filter having passbands of blue, green, and red. The additional passbands may be utilized to more closely match a color space and white point of a projector in which the filters are used. The shaped glasses and projection filters together may be utilized as a system for projecting and viewing 3D images.

Abstract: A multiple port valve plate assembly for use with a vacuum drum in a labeling apparatus. The valve plate has a first stationary vacuum cavity which is supplied with one level of vacuum suitable for picking up a label segment from a cutter with limited tension. The valve plate has a second, floating cavity, which is supplied with another, higher level of vacuum suitable for firmly griping the cut label segment as an adhesive is applied to the label segment. The valve plate has a third stationary vacuum cavity for suitable for holding the label at a lower vacuum pressure while the label is being transferred to a container. The third cavity may be further divided into a label application segment with an even lower vacuum pressure. A pressure port is also provided adjacent the third cavity for facilitating release of the label from the vacuum drum as it contacts the container.

Abstract: A machine and method for handling a plurality of articles, and a feed apparatus for transporting the article between a first station and a second station. The machine generally includes a conveyor which supplies a stream articles to an infeed station and a feed apparatus for indexing the articles. The feed apparatus includes at least one pocket shaped to at least partially receive one of the articles for transport the article from the first station to the second station and a guide section configured to separate the first one of the articles from the second one of the articles for movement of the first one of the articles into the pocket, to control movement of the second one of the articles during separation of the first one of the articles from the second one of the articles, and to move the second one of the articles into the pocket upon further rotation of the feed apparatus.
