Abstract: An assembly is provided for selecting at least one vertically oriented planate article such as a disc-shaped wafer (10) from an array of such wafers. A carrier (20) holds the wafers (10) in a mutually spaced, substantially parallel relationship along a single horizontal file. Peripheral portions of each wafer (10) are supported in opposing guides (26) formed generally vertically along opposing first and second sidewalls (22) and (24), respectively, of the carrier (20). A frame (42) positions the carrier (20) so the file of wafers (10) extends substantially along a vertical plane (44) passing generally centrally of each wafer and of the frame (32). A rotatable shaft (62) extends parallel to the file and subjacent of the wafers (10). For selecting a singular wafer (10), at least one cam (64) is mounted to and rotates with the shaft (62) for engaging and displacing a randomly selected wafer (10) a desired distance upwardly along the guides (26) of the carrier (20).

Abstract: Apparatus is provided for releasably retaining an article such as an optical cable (10) for rotation of the article. A chuck body (31) is provided along with components (24, 26 and 46-48) for rotating the body (31) and the cable (10) about a common central axis (33). A jaw (34) is affixed to the body (31) and disposed generally laterally of the axis (33). A movable jaw (35) is provided having at least mating surfaces which are complementary to the fixed jaw (34) for mounting thereto and grasping therebetween the cable (10) disposed about the axis (33). Magnetic devices are associated with the jaws (34 and 35) for releasably mounting the movable jaw to the fixed jaw for releasably retaining a cable (10) therebetween. For example, first and second magnets (36 and 37), respectively, may be made a part of a jaw such as movable jaw (35) and be disposed astride the central axis (33).
