Abstract: A tool which can be remotely operated to precisely measure the downcomer annulus width at the elevation of the top guide support ring. The measuring tool has a support frame adapted to be grappled and then hooked onto the upper rim of the shroud, and a measuring subassembly mounted on the support frame. The measuring subassembly has a contact block mounted on a bearing-mounted slider. The slider is translatable between a retracted (i.e., "home") position and an extended position in response to actuation of a cylinder mounted on the support frame. When the tool is properly installed on the rim of the shroud, the slider travels radially outward in response to actuation of the cylinder until the contact block abuts the opposing inner surface of the reactor pressure vessel wall, i.e., the slider is stopped.

Abstract: A wrench selector provides for the quick and accurate checking of the dimension of a nut or bolt across the flats thereof, in order to determine the corresponding size of the wrench or socket required for use therewith. The selector incorporates two jaws, with the first jaw extending from an elongated scale and the opposite jaw extending from a body sleeve through which the scale slides. The scale includes several rows of dimensional numbers thereon, with each of the numbers corresponding to a distance between the two jaws. The numbers are staggered diagonally across the face of the scale, in order to spread them for greater legibility. The body or sleeve includes a set of windows spaced laterally thereacross, which in combination with the diagonal array of dimensional numbers, results in only a single one of the dimensional numbers being exactly aligned within a corresponding one of the windows for any measurement.

Abstract: The linear measuring device comprises a rail (1) with a fixed measuring jaw (4) and a slide (5) with a movable measuring jaw (6). A holding member (9) with a handle hole (10) is adjustably mounted on the rail (1). The slide (5) has a ring (20) arranged displaceably therein. This ring is connected with a clamping piece (30) via connecting elements (36, 39).

The arrangement of handle hole (10) and ring (20) offers the advantage that maximally precise measurements can be quickly performed in correspondence with a scissor-like operation of the device.

Abstract: A measurement tool adapted for measuring surfaces of a known desired curvature and specifically grooves, holes, chips, gouges, chafing and/or out of round areas therein. The measurement device is constructed with an attachment member having a curvature matching the "set up" curvature of the part to be measured. The measuring member or probe, is sharpened to permit it to extend through an aperture formed in the attachment member for facilitating its initial setting relative to the attachment member and the surface to be measured. Any movement of the probe during measurement is then a manifestation of a deviation from the original "set up" curvature.
