Abstract: A machine tool to machine a workpiece including linear slide blocks supported one by the other on a pedestal to present a mounting surface for supporting a workpiece, a support head including a rotary indexing table that in turn supports an elongated cutter bar the support head to define an outwardly projecting cantilever end portion that is in turn supported by an outboard support, a cutter tool supported for rotary movement about an axis transverse to the extended length of the cutter bar, a drive means extends along the cutter bar for rotating the cutter tool and a collet chuck for engaging the cutter tool located remote to bearing seats to prevent radial distortion of such bearings when the cutter tool is engaged.

Abstract: A machine tool to machine a workpiece includes linear slide blocks supported one by the other on a pedestal to present a mounting surface for supporting a workpiece, a support head includes a rotary indexing table that in turn supports an elongated cutter bar the support head to define an outwardly projecting cantilever end portion that is in turn supported by an outboard support, a cutter tool is supported for rotary movement about an axis transverse to the extended length of the cutter bar, a drive means extends along the cutter bar for rotating a cutter tool. The drive to rotate the tool in one embodiment takes the form of a belt extending between pulleys one of which drives the tool and the other is coupled to the electric motor in the drive head. A hydraulic motor is mounted in the cutter bar to rotate a tool according to a second embodiment.

Abstract: Method and apparatus for increasing the efficiency and the performance of normally aspirated internal combustion engines. A combustion air intake housing including a fuel injector for introducing an atomized spray of highly volatile, preferably non-petroleum based, combustible fuel in a region of convergence of a plurality of convergent, progressively operated intake ports formed in the air intake housing. The highly volatile combustible fuel rapidly and significantly cools the intake (combustion) air, thereby densifying the air. Thus, the cooled air contains, per unit volume, a greater quantity of combustible matter to be introduced into the engine combustion chamber(s) which consequently increases the explosive combustion charge within the chamber(s) upon ignition of the charge, thereby enhancing engine efficiency and performance.
