Abstract: The present invention relates to an assembly which includes a display card-forming section and an identification card-forming section. The identification card-forming section includes a first backing sheet and contains an identification card backing region. Further included is a first adhesive layer, a first release layer joined to the first side of the backing sheet and to the first adhesive layer except at the identification card backing region where there is an opening in the first release layer, and a transparent lamination sheet. The transparent lamination sheet has a first side, joined to the first adhesive layer.

Abstract: An envelope sheet assembly for securing into a brochure or binder includes two sheets overlying one another so that the assembly is of uniform thickness to facilitate printing thereon. The envelope sheet assembly is preferably 81/2 inches by 11 inches in size, and the envelope is preferably 11 inches by 41/2 inches. Permanent pressure sensitive adhesive is employed to form the envelope and is applied to the sealing flap, with a removable strip to protect the adhesive coated flap. Perforations permit easy removal of the envelope from the assembly.

Abstract: An identification wristband and corresponding adhesive identification labels are supplied by a single printed laminated sheet material. The latter comprises a paper sheet of which a wristband part has a die cut, elongated, wristband strip and a label part having a plurality of die cut adhesive labels. The die cut wristband strip and the die cut labels are printed with correlated identification indicia. The under side of the label part is releasably adhered to a release sheet. A flexible transparent film is releasably adhered to the under side of the wristband part of the paper sheet. The transparent film is die cut to form two contiguous rectangular areas, each slightly larger than the firmly adhered die cut wristband strip. These die cut film areas are separated by a longitudinally bisecting line and each has a longitudinal, integral, tabular extension at opposite ends. To form a covered wristband, the die cut strip of the paper sheet is pressed on the printed side to separate it from the sheet.

Abstract: An automatic control of the operation of a machine used for excavating drifts, tunnels, stopes, caverns or the like of a predetermined profile having a rotatable head (10) and cutting arms (14, 16) mounted on the head for rotation therewith, extending in the direction of excavation with at least one cutting arm (14, 16) being radially pivotable. The angular position (.phi.) of the head (10) is continuously measured and the output signals from these measurements are processed by the computer (44) which controls the angular positions of the head and of the arms according to a predetermined profile code or program stored in the computer memory for cutting the predetermined profile. Additional sensors (54,56) may be provided to control other parameters such as RPM of the rotating head, the force exerted on the arms, the positioning of the machine and the like.
