Abstract: A measuring device, such as a micrometer or other form of dimensional measuring instrument, is provided which is operable to indicate dimensional measurements made thereby in numerical form on a display, such as an electronic digital display. The measuring device or micrometer is controlled to generate digital electrical signals which are indicative of a measurement, which signals of each measurement are recorded in an electronic memory which may be supported by the device or connected thereto. The memory is employed to both indicate each measurement as it is made and to record all or selected measurements made for future reference. Other information generated, for example, by a suitable input means such as a keyboard, and defining such variables as part number, part lot, time and date of measurement, etc. may be recorded in such memory along with the recording or recordings of data defining the measurements made.
Abstract: A gage block is designed as a stepped sine block to produce commonly used angles when used with a conventional sine bar without the use of conventional gage blocks. Reference surfaces parallel to one or more bases are provided to produce the desired number of commonly used angles.
Abstract: A device which measures the overall diameter of groups of hairs or fibers and reduces the work required to obtain their statistical parameters. In the preferred embodiment an outer hollow cylinder is mounted between the measuring surfaces of a micrometer. An inner edge of a trough made in the cylinder articulates with an edge of a half cylindrical portion of a piston moving within it by means of a handle; the two parts thereby making a window with diametrically opposed halves. A spring presses the piston edge to the trough edge by sliding the piston on slopes against two parts with short steps and a block disengages one end of the piston to let hair in when open. An elongated step with a railing is placed under the piston half cylinder thus making the window into a face of a hollow triangular prism. The railing rises higher than the edge of the trough so that when the piston and trough edges nearly meet the elongated bottom step must turn and bend the hairs.
