Systems, methods and slice thickness gauges that are capable of providing customers with identifying features representative of varying thicknesses of food products slices available for purchase, and with which customers can place orders for sliced food products having a desired slice thickness. The method includes providing a slice thickness gauge to a customer. The slice thickness gauge includes a plurality of identifying features each identifying feature corresponding to a thickness of a food product that may be produced by the attendant. The identifying features include a numeric value that is an integer devoid of fractions and decimal values and corresponds to a slice measurement that can be configured on a slicing machine.

A geometrical error measurement method for a feed drive system includes entering coordinate values of four vertices of a virtual regular tetrahedron, mounting a position indicator to an end of a main shaft of a feed drive system, mounting three center mounts at three respective vertices of the four vertices except for the remaining vertex at which the main shaft is positioned while moving the main shaft of the feed drive system sequentially from one vertex to another according to the entered coordinate values, measuring distances between each of the four vertices indicated by the three center mounts and the position indicator with a double ballbar, and calculating a geometrical error from the measured distances.

A step gauge includes: measurement blocks each having reference measurement surfaces; interval blocks each interposed between a pair of ones of the measurement blocks to keep a distance between the pair of ones of the measurement blocks at a predetermined distance, the measurement blocks and the interval blocks being alternately aligned one by one in one direction. The measurement blocks and the interval blocks each have a coefficient of linear thermal expansion of less than 0.0310.sup.6(1/K) and have through holes aligned in the one direction. The step gauge further includes a tie rod inserted in the through holes and countersunk screws respectively fixed to ends of the tie rod. The tie rod is made of a material having a coefficient of linear thermal expansion of less than 0.510.sup.6(1/K).

A pipe spacing wedge system including a pipe spacing wedge assembly, with the pipe spacing wedge assembly including a wedge-body. The wedge-body may be defined by a front-side, a back-side, a right-edge, a left-edge, a top-edge, and a bottom-edge. The front-side of the wedge-body includes a plurality of stepped surfaces and the top-edge includes a sharp point. The pipe spacing wedge assembly is structured and arranged to assist a user in setting a variety of specific gap-distance between sections of pipe and pipe spacing wedge assembly is intended to be driven between the two sections of pipe by the user to set the gap-distance.

A high-stability step gauge and a preparation method therefor, where the step gauge has a base body, the base body includes a pillar carrier disposed along a coordinate direction, gauge block mounting blocks are distributed on the pillar carrier, and gauge pieces are fixedly mounted on the gauge block mounting blocks. The high-stability step gauge has good accuracy and stability, a small size, and strong functions. Deformation errors caused by the step gauge due to factors such as a weight of the base body are effectively and prominently reduced by means of reasonable combination of the base body and the gauge block mounting blocks. The preparation method thereof provides a stable length direction low deformation performance by using a cylindrical rigid support as the base body. The sleeved gauge block mounting blocks have high fixed mounting stability, and positioning and assembly of the gauge pieces are accurate.

A precision fabrication form system for preparing a poured-concrete (with upwardly projecting anchor bolts) footing for anchorably supporting the base of an elongate, upright, structural-frame column. The system includes a reversibly stackable plurality of independent, intercooperative, fabrication-form templatesgrade, pedestal, base-plate, anchor-bolt and centerlinereversibly assembleable in a predetermined stack order above a prepared ground excavation into which concrete pouring to be associated with such a footing is to occur, certain ones of these templates being infinitely adjustable relative to one another and to the ground in both pre-pour and post-pour conditions to accommodate staged, precision, X-axis, Y-axis, Z-axis, and pitch, roll and yaw axes dispositions for the concrete and anchor bolts in such a footing.
