Abstract: A system for processing code contained in one or more selected files, before the code is linked to form an executable image, features means for determining the locations in memory where the code will be stored after it is linked, and means for revising the code to correspond to the determined memory locations. The object code files include code comprising a programming environment, such as LISP, and code input by a user. The user can delete selected portions of the programming environment. Read only, static, and dynamic memory are utilized and each portion of the code input by the user is evaluated to determine which memory is most appropriate.

Abstract: A drilling boom has an articulated arm 12 which carries a drill feed beam 28 on its outer end. Apart from the articulation 36, 38 provided by the joint at the outer end of the arm, the feed beam can rotate about two mutually perpendicular axes at the end of the arm. One of these axes is defined by the so-called rollover unit 44 and the other axis 92 is at right angles to the length of a drill rod on the feed beam and allows at least 180 degrees of rotation so that parallel holes can be drilled in all parts of the roof, floor and side walls of a heading.

Abstract: Improved internal tooling for a swaging apparatus for attaching fittings to tubing. The tooling includes a draw bolt having a head at one end adapted to be connected to actuating means such as a hydraulic cylinder at its opposite end. A straight cylindrical resilient expander sleeve is coaxially disposed on the draw bolt and is bracketed by a pair of split, circular, anti-extrusion rings located in mating seats formed in facing end surfaces of the draw bolt head and a seal bushing. The facing surfaces of the head and bushing are further configured to include a ramp surface extending between the surface of the draw bolt and split ring seats.
