Abstract: The tool kit comprises a set of angle gauges for measuring angles in a workpiece being formed in a sheet metal bender, and printed math tips and charts related to the angle gauges. Each angle gauge has an elongated shape with juxtaposed longitudinal base surface and longitudinal angled surface, and an indicia thereon indicating a nominal angle. The angled surface makes a true angle with a transverse projection of the base surface. This true angle corresponds to the sum of the nominal angle on the indicia plus a supplement angle. The nominal angles on the angle gauges in the set are different from each other, and the supplement angle is common to all angle gauges in the set. The supplement angle corresponds to the slope of the nose bar in the sheet metal bender. The entire set can be used on a same bender to measure different angles.

The gage is secured to the calibrator plate which holds the gage in an orientation that simulates a rotor blade with trim tabs at zero degrees so that the gage can be zeroed.

Once in position, the bender is applied to the trim tabs adjacent to the gage and tightened using thumb screws. The handle of the bender allows the trim tabs to be adjusted while verifying that the amount of adjustment indicated by the gage dial indicator matches the preselected angle.

Abstract: An economical, compact guide for introducing multiple bends in one or more planes in a pipe, conduit, or other tube-like item. The guide has a gauge section rotatably attached to a mounting section and is affixable by means of a non-deforming clamp to the end of a pipe segment to be bent.

Abstract: The novel inclined plate 360 degree absolute angle sensor is designed to measure the absolute angle created by a base and a rotating surface. The assembly contains a metal inclined plate positioned above four coils so that coils one and two are at the minimum and maximum distance from the plate respectively, while at the same time, coils three and four are equidistant from the inclined plate. Rotation of the plate around a centerline, changes the distance that all four coils with respect to the inclined plate which, in turn, creates a change of the inductance of the coils. This change in inductance may be measured with alternating current bridge technologies in order to provide a measure of absolute angular position of a rotating surface with respect to the base.
