Abstract: A single-handedly operated citrus fruit segmenter having first and second arms such that squeezing the arms into a closed position causes a curved movable scoop to extend into a citrus fruit proximate to a triangular blade and form a segment-shaped compartment. The actuation of the curved movable scoop occurs by a user squeezing the first arm toward the second arm. A pin on the first arm is operatively connected to an elongated slot of a cam mechanism such that the rotation of the first arm about its pivot location causes the cam mechanism to rotate about its own pivot location. Therefore, the cam mechanism, being also connected to the curved movable scoop, forces the curved movable scoop into the citrus fruit.

Abstract: A miter saw is adapted for performing lengthwise, or rip, operations on a work piece such as wood. A back support arm is positioned off-center such that the work piece can be inserted under the miter saw substantially parallel to the blade. An arcuate aperture in the back support arm ensures that bevel adjustment properly aligns the blade with the blade slot during bevel cuts. An adjustable rail enables the work piece to be positioned in either a normal position, for crosswise cuts, or an orthogonal position, for lengthwise cuts. A toggle switch overrides the on/off switch on the handle, useful when the work piece is fed from behind. Two separate sleeves cover the blade, assuring safety during operation for both lengthwise and crosswise cuts. A tensioning board feed roller holds the work piece in place during lengthwise cutting.

Abstract: A tube cutting machine comprises a tube secured in a chuck tightened against an outer tube wall and by a mandrel expanded within the tube against the tube inner wall opposite the chuck. A blade with a conical body side on the tube body side advances into the tube at the body side angle, eliminating longitudinal force against the tube body and accumulation of tube material on the blade body side. In alternative embodiments, either the tube or the blade can rotate. As the blade edge enters the tube wall, the blade end side, opposite the body side is also conical and pushes the tube cut portion longitudinally away from the tube body, causing the tube before the blade to neck under the longitudinal force imposed by the blade end side. The blade is reversed when the neck weakens and is unable support the tube cut portion but has not yet broken, referred to as the failure point. The blade is then withdrawn and the neck is snapped off. The failure point is detected by a rod urged transversely against the tube end.
