Abstract: A screwdriver tool provides positive engagement with screw having a head with a straight slot. An end portion is substantially flat, but is wider at its midpoint than at its ends. A tapering segment extends from the end portion and an engagement area is defined on the side of the segment. Engagement initially occurs at a location intermediate to the ends and midpoint of the end portion. As torque on the screwdriver is increased the engagement extends toward the midpoint and up the side of the segment.

Abstract: This disclosure depicts a novel reversing conveyer track for changing the orientation, direction and spacing of books for use with book construction machinery. The reversing conveyor track first comprises a means for accepting the books and for establishing a predetermined spacing of the books. The means for accepting the books outputs the books with a predetermined velocity. The conveyor track further comprises a means for orienting and directing the books which is attached to the means for accepting the books. The orienting of the books is a change from an edge position to a side position and the direction of the books is a direction of movement different from the input movement direction of books to the means for accepting the books.
