Abstract: A lettering apparatus and a lettering method for a beer barrel are provided. The lettering apparatus includes a worktable, a hydraulic push device installed on the worktable, a first lettering device, and a second lettering device. The second lettering device includes a rotatory disk seat with the Z-axis as its axis. The rotatory disk seat is adapted to install a cask thereon. A circumferential surface of the rotatory disk seat is provided with an inner mold for lettering on an inner side of the cask. The first lettering device includes a connecting frame. The connecting frame is movable linearly along the Y-axis. The connecting frame is provided with an outer mold for lettering on an outer side of the cask. The hydraulic push device controls the outer mold of the connecting frame to move linearly along the X-axis for the outer mold and the inner mold to letter on a side wall of the cask.

Abstract: A hand tool includes a body having first and second surfaces spaced from each other in a height direction. A marking unit is formed on the first surface and includes a groove formed in the first surface of the body. The groove includes a bottom face spaced from the first surface of the body in the height direction. An embossed character protrudes from the bottom face towards the first surface and has a stepped portion to provide a clear indication effect.

Abstract: A marking (7) that indicates inherent information about a stator (2), is formed of recesses inscribed at a predetermined position on the outer circumferential surface of a laminated iron core (21) of the stator (2), by melting a magnetic thin plate with a laser beam. The marking (7) is formed of recesses in the outer circumferential surface of the laminated iron core (21), i.e., in the outer circumferential surface, at the laminated side of the magnetic thin plate, of the laminated iron core (21). Accordingly, friction or the like does not peel off the marking.

Abstract: An invisible information mark is provided on a facet of a diamond gemstone by applying a plasma resist to the exposed surface of the gemstone, applying an electrically conducting layer of metal to the region where the information mark is to be formed, ablating a selected zone of the metal and resist layers by ultraviolet laser thus forming a mask on the surface of the facet, electrically connecting the metal layer and plasma etching the facet through the mask, thus forming a mark of appropriate depth on the surface of the gemstone.

Abstract: An assembly for creating free form laminated objects, such as a throwing toys or napkin ring that can be printed or decorated by the use of printer or copier without jamming. The assembly includes a sheet of cardstock or thin printable sheet material, a sheet of transparent laminated plastic and intermediate adhesive layer that adheres the cardstock sheet and laminated sheet together. The cardstock sheet has a die cut outline configured to the desired shape of an object. The laminated sheet has a die cut outline substantially extending outside of the outline on the cardstock sheet, to allow laminated sheet to fold over and entirely cover the cardstock area within the cardstock die cut outline. The assembly has a substantially constant thickness and substantially flat upper and lower surfaces so that the assembly can pass through a printer or copier without jamming.

Abstract: An assembly for creating laminated cards for printing by a laser printer has a backing sheet. The backing sheet has a first side with a release coating, and a second side with a printable surface. The assembly also has a card which has been cut from the backing sheet. A lamination sheet adhesively adheres to the first side of the backing sheet and to the cut card. A lamination strip which has been cut from the lamination sheet has a first portion which adheres to and covers one surface of the card. The lamination strip also has an integral second portion which adheres to the backing sheet adjacent to the cut card. The lamination strip maintains the cut card in the same position relative to the backing sheet that the card had prior to being cut. The assembly has a substantially constant thickness and substantially flat upper and lower surfaces so that the assembly can pass through a complex paper path without jamming. A method for creating laminated cards from such an assembly has several steps.

Abstract: Labelstock for in-mold labeling purposes which is characterized by a tensile ultimate elongation per ASTM D-882 of at least about 10% in one or both of the machine and transverse directions, and which contains a sufficient amount of one or more slip additives to prevent a significant degree of edge-welding between adjacent stacked sheets of the labelstock on a high type die cutter in an in-mold labeling process.

Abstract: An organizer is disclosed herein for identifying a workpiece with a noted project or owner on a work chart. The chart has rows and columns containing indicia characterizing the workpiece and further including visual labels of a given shape and identification color. An identical set of labels is provided separate from the chart and having corresponding shape and color to those labels carried on the chart. A selected one of the separate labels is affixed to a particular workpiece so as to identify the workpiece with a particular row and column of indicia. A marking pen and an eraser is included to complete the organizer.

Abstract: A tool of a metal-cutting machine provided with numerical control has an information data carrier for storing various data of tool characteristics such as the length, diameter, service life and other parameters of the tool. The data carrier is formed by an electrically erasable programmable read-only memory which has a large storage capacity. The memory is rigidly inserted in the tool or tool holder and is protected against damage and contamination. Inadvertent release and loss of the data carrier are avoided.

Abstract: Disclosed is a method of manufacturing multilayer identity cards by electrophotographically reproducing identity information on a card core material and then laminating protective film on both sides of the core material. In preferred embodiments, the core material itself may be made up of several layers with additional security markings thereon. A relief grid image or a hologram can be inserted into the card core prior to lamination. In a further embodiment, after lamination, the identity card blank is photomechanically scanned and positioned in accordance with existing control marks and punched to produce the finished identity card.

Abstract: A method for treating a gem stone to cause a marking thereon, wherein a photoresist resin is secured to the stone, a photographic film bearing the desired marking is applied over said resin, said resin is developed by exposing same to a light source, the exposed portions of said resin, as well as said film, are removed, and the thus-treated portion of the stone is subjected to a cathode bombardment in such a way that etching of the stone occurs in those locations which are not protected by said resin.
