Abstract: A bucking and wrapping gauge suitable for installing windows is provided. The bucking portion of the gauge provides a constant setback distance for a window buck relative to outer edge of a window opening without using a ruler or other measurement tool. The wrapping portion of the gauge provides a constant wrapping distance that partially compensates for the thickness of the window buck so that it may be determined where to install an interior wall relative to a window frame so that a window wrap and the interior wall abut at a substantially right angle. The wrapping and bucking gauge may be implemented as a separate wrapping gauge and bucking gauge.

Abstract: An Almen type gage to measure the deflection of a test strip relative to a supporting surface to provide an indication of shot blasting intensity includes curved surfaces extending from the support surface for supporting the test strip. A holding block is also mounted on the support surface. Plungers carried by the holding block opposite the curved surface clamp the test strip between the spring loaded plungers and the curved surface.

Since the weight of the holding block is not borne by the test strips, the holding force is constant and the weight of the holding block does not corrupt measurement of the deflection of the test strip.

Abstract: A test apparatus for measuring the relative flatness of a side of an object. The test apparatus includes an electronic probe immobilized in a surface plate such that the contact member of the electronic probe is adjacent to the plane of the surface plate.

Abstract: A metrological apparatus has a movable arm 15 which moves up and down between two bearing members 13, both of which define datum positions for the arm 15. The arm 15 has air bearings on the bearing members 13, so that it adopts a position equidistant between the bearing members 13. In this way, the position of the arm 15 contains the average of the errors in the two datum positions defined by the bearing members 13. Where the bearing members 13 have symmetric errors, these will be cancelled. Since the path of maximum straightness of movement of the arm 15 is spaced from the bearing members 13, it is possible to put a workpiece 3 in this path and a turntable 5 for supporting the workpiece 3 is arranged to have its rotational axis in line with the path of maximum straightness.

Abstract: A core 4 is mounted on a machine tool for indexable rotation about an axis 2A, so as to bring respective cassettes 10 into position where they can be operated on by tools held in the machine tool spindle 6. The cassettes 10 may hold workpieces 14,14A for machining. After machining, the workpiece 14A is measured by a probe 20 held in the machine tool spindle 6.
