Abstract: A tube cutter mechanism supports an arm from which a tube supporting anvil extends, the anvil being aligned with the tube cutter mechanism for cutting the supoorted tube. During cutting, an axial force is imposed on the tube and anvil. The arm is formed such that it bends in response to the force, storing energy such that rotation of the tube occurs for more than one revolution of the tube without advancing the cutter wheel. The device is formed of molded glass fiber reinforce nylon, preferably ZYTEL. In a second embodiment, the arm does not bend and the anvil is constructed so as to bend relative to the arm in response to the axial cutting force permitting rotation of the tube during cutting beyond a single revolution without advancing the cutter wheel. The anvil advantageously does not have a cutter wheel for burnishing the tube to remove oxides during cutting.

Abstract: A slotting apparatus has a slotting tool for producing a slot of a substantially arcuate cross section axially in an inner circumferential surface of a tubular workpiece held in position. When the slotting tool moves in one direction axially in the tubular workpiece, it follows an arcuate path by moving progressively toward and away from the inner circumferential surface of the tubular workpiece. The slotting tool cuts off the inner circumferential surface of the tubular workpiece, forming an arcuate slot therein. When the slotting tool moves back, it is spaced from the slotted surface region of the workpiece, and travels along a straight path back to its starting position. The slotting tool is supported on a tool support angularly movably supported by first and second link arms in a casing.

Abstract: A damped, cantilevered support arm for a machine tool position monitoring device rigidly attached to the machine tool by a pair of spaced bolts for relative movement with a machine part along a longitudinal axis. The line of centers through the bolts is oriented along the longitudinal axis and the arm is mounted with shims located between its base and the machine tool part to allow limited effective freedom of movement of the support arm around the line of centers in a direction normal to the longitudinal axis. A squeeze-film damping chamber is provided between the spaced shims for reducing the response of the support arm in the normal direction during relative movement along the longitudinal axis. A boundary O-ring seal together with the thickness of the spacers, defines the damping chamber.

Abstract: An apparatus for severing thin boards from squared timber includes a guide urface upon which a squared timber is conveyed and pressed against a cutting edge of a blade, as well as a counter pressing edge. The adjustment of the distance between the guide surface and a plane parallel thereto which extends through the blade cutting edge (i.e., the thickness of the thin board to be cut) is effected by relative adjustment of the blade cutting edge to the guide surface in an inclined plane which forms an acute adjustment angle .alpha. with a line normal to the guide surface. Because of the relative adjustment of the blade cutting edge to the guide surface along the angle .alpha., when a different board thickness is desired, the distance between the blade cutting edge and the counter pressing edge in the cutting direction is automatically adapted. In a preferred embodiment of the apparatus, the width of an exit guide channel for the severed thin boards can also be simultaneously set to the desired board thickness.
