Abstract: An apparatus for measuring the profile of portions of an article located within a predefined plane. Each portion is scanned, such as by an optical micrometer providing a beam of radiant energy, to determine its dimension. The distance between each portion and a vertical reference is also scanned to determine its dimension. The article is rotated about an axis intersecting the predefined plane within the scan of the beam and is axially moved along an axis parallel to the intersecting axis within the scan of the beam so that the dimension of each portion and its distance from the vertical reference can be determined. The apparatus may be used in combination with a cavity identification system to control manufacturing employing multiple molds.

Abstract: An alcove for conducting molten glass to a plurality of forehearths for delivery to glassware forming equipment, comprising a series of zones with a trough extending through the zones and a barrel vault roof over the trough in each zone, the vault bearing on blocks at the top of the sides of the trough carrying burners, the vault having keystones formed to provide side channels over side portions of the stream of molten glass in the trough and a central channel over the central portion of the stream.
