Abstract: An apparatus and method detect defects in a metal surface. The apparatus is configured to move an eddy coil relative to an underlying metallic surface along a plurality of generally parallel and adjacent scan paths, and to receive from the eddy coil an oscillating signal induced at said coil as it is moved along each path. A representation of the received oscillating signal in relation to each one of a plurality of adjacent scan areas within each path is recorded, and a two-dimensional grid-like map showing the signal representations relative to each scan area is displayed. Defect location is facilitated by a further function of the apparatus and method, by which user input to an interface causes a light source to illuminate a selected part of the metallic surface.

Abstract: A level and protractor tool (100) includes a body (102) with three sections. The first section (106) includes a spring clip (108) mounted on the body. The spring clip is adapted to be attached to an item that is to be bent or otherwise measured with the level and protractor tool (FIG. 6). The second section (128) is contiguous with the first section. The second section includes a mounting pin (132) defining a rotational axis for both a pointer (134) and a degree wheel (136) having a pendulum weight (306). The degree wheel and the pointer are positioned with respect to the mounting pin for rotational movement about the mounting pin independent of one another. The third section (142) includes a bubble level or spirit vial (144) and is attached perpendicularly to the second section and parallel to the mounting pin.

Abstract: A level/protractor tool which includes two or more sections pivotally joined to facilitate angular displacement. One or more sections house level-indicating spirit vials. Angular displacement indicia marks are imprinted on each section at its juncture with an adjoining section to visually indicate the degree of angular displacement between adjacent sections.
