Abstract: An apparatus for grouping electronic price labels (EPLs) to form an electronic sign. The apparatus primarily includes a frame member which defines a plurality of bays arranged in a single line for containing the EPLs. The apparatus additionally includes a product description sheet mounted to the frame member including apertures for exposing displays within the EPLs. Optionally included are a product description sheet holder which mounts to the frame member for retaining the product description sheet against the frame member and a base for supporting the frame member on a flat surface. A method of grouping EPLs includes the steps of providing a frame member defining a plurality of bays arranged in a line for containing the EPLs, retaining the EPLs within the bays, placing a product description sheet adjacent to the frame member, and orienting apertures in the product description sheet to expose displays within the EPLs.

Abstract: An electronic price label (EPL) system including groups of electronic price labels and method of managing the groups which facilitate group definition, assignment of EPLs to groups, assignment of items to EPLs, and assignment of prices to items. The system includes a plurality of EPLs arranged in a single line of bays within a sign to define a group. A computer coupled to the EPLs defines the group, assigns the EPLs to the group, and assigns item identification numbers and prices to the EPLs. A storage medium stores group definition information, EPL assignments to the group, and item assignments to the EPLs. The storage medium additionally stores a price identifier, which is preferably added to the item identification numbers to form modified item identification numbers.

Abstract: An electronic price label (EPL) system including groups of electronic price labels and method of managing the groups which facilitate group definition, assignment of EPLs to groups, assignment of items to EPLs, and assignment of prices to items. The system includes a plurality of EPLs arranged in rows and columns within a sign to define a group. At least one of the rows includes a plurality of EPLs and at least one of the columns includes a plurality of EPLs. A computer coupled to the EPLs defines the group, assigns the EPLs to the group, and assigns item identification numbers and prices to the EPLs. A storage medium stores group definition information, EPL assignments to the group, and item assignments to the EPLs. The storage medium additionally stores a price identifier, which may be incorporated into the item identification numbers.

Abstract: A process for improving the technique of measuring residual stress by x-ray diffraction in pieces of nickel-base alloys which comprises covering part of a predetermined area of the surface of a nickel-base alloy with a dispersion, exposing the covered and uncovered portions of the surface of the alloy to x-rays by way of an x-ray diffractometry apparatus, making x-ray diffraction determinations of the exposed surface, and measuring the residual stress in the alloy based on these determinations. The dispersion is opaque to x-rays and serves a dual purpose since it masks off unsatisfactory signals such that only a small portion of the surface is measured, and it supplies an internal standard by providing diffractogram peaks comparable to the peaks of the nickel alloy so that the alloy peaks can be very accurately located regardless of any sources of error external to the sample.
