Abstract: The present invention relates to a device for locking in a set position along arched tape (5) preferably intended for measuring and marking. The tape is guided in a trough-shaped member (10) constituting one part of a locking mechanism and in which the tape is oriented with its convex side facing away from the bottom of the member. An elastically deformable locking member (17) constituting a second part of said locking mechanism has a part (16) displaceably disposed in a direction towards and away from the convex side of the tape guided in the trough. When the locking means is enabled, the part (16) has a radius of curvature substantially corresponding to that of the arched tape, and this radius of curvature may be different from the radius of curvature of the tape in the disabled state. The thin edges of the tape (5) will thus be urged against the corners of the trough, whereby an effective lock is obtained between the tape and the trough-shaped member in the region of the elastically deformable tape.

The first and second gage parts are joined together, preferably by a hinge, to form a generally circular ring adapted to fit about the tubular member. Each flute engaging surface includes a plurality of stepped arcuate flute engaging portions that are spaced at radii from the center of the ring corresponding to nominal diameters to be measured.

The wheel is loosely mounted so as to stay in contact with the coiled tape as it is extended and its wound diameter decreases, either by a fixed stub pin axle and slot arrangement or by a fixed arbor and large, open wheel center.

Abstract: A leveling tool for accurately marking a pair of points on a horizontal or vertical line, for example for use in hanging pictures or shelves, has an elongate bar provided with a fixed tab member, a longitudinally movable second tab member and bubble gauges set parallel with and at right angles to the length of the bar. The fixed tab member is used as a pivot placed on one of the points, and the tool is swung around the pivot until one or other of the bubble gauges is level. The second tab member is then used to mark the second point.

A third capacitor is influenced by the dielectric value of the two fluids but in a manner independent of the tilt angle of the container. The fourth capacitor has a capacitance value influenced only by the dielectric constant of one of the two fluids. Based on the four capacitance values, circuitry is provided for generating a signal relating to the angle of the container.
