    摘要: An offset rock bit (12) has a steering face (28) and a shoe (30) provided by a recess formed into the steering face (28). A slot (66) formed into the shoe (30) for receiving a pull back adapter (50) in a centrally located position in the forward end of the offset rock bit (12). The pull back 5 adapter (50) has a pull back eye (52) with a central axis (62) which is aligned with a centrally disposed longitudinal axis (20) of the offset rock bit (12) and the tool string (10). This aligns the pull back eye (52) of the pull back adapter (50) with a borehole formed using the offset rock bit (12). The pull back adapter (50) also includes side edges (54, 56) which are configured for centering the pull back adapter (50) and pull back conduit within the borehole.

    摘要: A plate for supporting one or more sheets of originals to be copied and a sheet of sensitized media is supported so as to minimize sag in one direction across the plate. The plate may be inclined with the top and bottom edges of the plate entirely supported or only supported at location(s) spaced inwardly from the edge of the plate. When a cover, such as a flexible curtain, is mechanically pressed against the plate, as by a roller, air gaps between the originals and sensitized media are minimized due to this plate support system. This improves the speed at which high quality prints can be obtained.

    摘要: A truss assembly apparatus (10) comprises an elongate table (12) with a presser carriage (14) supported for movement along the table. The carriage (14) supports a roller (116) for embedding fastener plates into precut truss members positioned on the table (12). Two clamping assemblies (40) are mounted on the table (12) to define a pair of truss assembly zones and an intermediate truss transfer zone. Each clamping mechanism (40) is selectively actuated to effect positive clamping engagement of the precut truss members or semi-complete truss positioned therein. A plurality of lift means (80, 100) are mounted in the table (12) for facilitating advancement of the truss during assembly.
