Abstract: A robotic positioner for use with an automated processing system, such as an automated welding system, for example, includes a base, a support structure rotatably supported on the base, and at least one work surface supported on the support structure suitable for supportably engaging a workpiece. The support structure extends from the base at an angle relative to vertical, and the work surface extends at an angle relative to the support structure. In operation, a workpiece is secured onto a work surface while in a generally horizontal load/unload position. The support structure and work surface thereon is then rotated into an inclined work position relative to horizontal that is adjacent the automated processing system. Thereafter, the work surface is rotated with the support structure back to the generally horizontal load/unload position so that the workpiece can be removed and another loaded.

Abstract: A book stiffener of a type having a relatively flat, thin, elongated, rigid rotatable-strip (32) attached by a swivel mechanism (34, 108) to an outside surface of a book cover, also includes an indexing mechanism between the rotatable strip and the book cover for holding the rotatable strip in predetermined angular index positions relative to the book cover. The index positions include a stiffening position in which the rotatable strip extends across hinge seams (24, 26) of front and rear flap covers (18, 20) of the book cover, and a disabled position in which the rotatable strip extends more nearly parallel with a back binding (22) of the book cover so as not to substantially extend across the hinge seams. The indexing mechanism includes protrusions (102, 122) on one of the book cover and the rotatable strip and indentations (104, 124) on the other of the book cover and the rotatable strip, with a protrusion resiliently snapping into an indentation at the index positions.
