Abstract: A kinetic breaching assist tool includes a ram slidably positioned within a ram housing to be extendable forwardly out of the housing for breaching doors and other barriers. The ram housing is connected to an intermediate propulsion section that generates high pressure gas to drive the ram forwardly. The rear end of the propulsion section is connected to a firing mechanism assembly, which is actuated by an elongated trigger positioned within the confines of a manually graspable rear handle assembly. A forward handle assembly is mounted at the forward portion of the propulsion section to enable to tool to be conveniently and securely grasped by both hands.

Abstract: A device for measuring the normality of a hole in a work piece, especially in holes used in the building of aircraft. A probe fits within the hole to be measured and is fixed in the hole by contact at the upper end of the hole with a tapered portion of the probe, and at the lower end by a flared portion of the probe. An indicator assembly is connected to the probe by a bracket. The indicator assembly has an arm which contacts the surface of the work piece. The indicator assembly is rotated around the probe during use of the gage, and the arm is vertically displaceable as this rotation occurs. A dial indicator operationally connected to the arm will register any vertical displacement of the arm during its rotation, indicating any deviancy from normality of the measured hole.

Abstract: A depth stop attached to a drill for producing precise countersinking in drilled holes. The depth stop produces an accurate and precise countersink in drilled holes by limiting the depth to which a drill bit can drill through a work piece. An audible click occurs for every 7.5 micron change in depth in the preferred embodiment. The depth stop is configured such that attempts to over tighten the lock screw which fixes the depth amount will not damage or deflect the working parts of the device thereby producing accurate and repeatable results.

Abstract: A portable power drill having an automatic drilling cycle for feeding a rotating tool bit to a workpiece to effect the desired operation. The drill uses a rotary gerotor pump to pump hydraulic fluid used in its system, and pressurized air to operate the hydraulic pump. The drill has a clamping assembly which clamps the unit on a workpiece before the drill bit is advanced toward the workpiece. The drill also has an integral drill spindle-planet carrier area which adds to its operability and reliability.
