摘要:
A device is disclosed for the application of customizable indicia to the outer surface of a smoking article such as a cigar. The device employs thermal means to apply indicia in a controlled and customized manner that allows easy branding of cigars. The device includes a thermal branding head, a cradle for holding the smoking article, a heating element, a control circuit to control the temperature of the heating element and branding head, an actuator to move the branding heat into contact with a cigar contained within the cradle and a timing circuit to determine how long the branding head shall be in contact with the cigar.

A portable engraving system comprises an enclosure adapted to operably accommodate an engraving device, wherein the enclosure comprises an adjustment system. The adjustment system comprises one or more adjustable devices, and the adjustable devices are adapted to adjust a distance between the enclosure and a work surface thereby allowing adjustment of the distance between the enclosure and the work surface, whereby the enclosure is adjustable with respect to the work surface. The enclosure further comprises an opening wherein the engraving device is operably positioned thereto, whereby the work surface is accessible to the engraving device therethrough. The enclosure is positionable adjacent the work surface and operably disposed thereto.

A brick, and similar article, engraving process utilizes a CO2 continuous beam laser guided over a beam path which outlines a graphic image on the article being engraved and repeats the beam path at incrementally spaced positions of the beam until the width of the graphic image is defined, thereby concentrating the heat of the laser engraving process in the vicinity of the graphic image during the process. The graphic image may be engraved in one or two passes of the beam over the surface of the article being engraved, such as common construction brick, wherein the engraving has minimal reflectivity and is of a uniform dark color providing an enhanced aesthetically pleasing engraved article.
摘要:
A method and device for burning a pattern in a surface of wood or other charrable material. The device generally comprises a ceramic body having a raised pattern defined on a surface thereof and means for locally heating the raised pattern to a temperature sufficient to burn a pattern in a surface of wood contacted by the ceramic body. While various heating means are possible, two noted heating means are an electrically-resistive wire or an electrical-conductive ceramic material embedded in the ceramic body in proximity to the raised pattern, both of which serve to locally heat the raised pattern when current from a suitable electric current source flows therethrough.

Embodiments of methods and an apparatus for creating points or areas of laser-induced damage inside a transparent material are disclosed. One or more embodiments of the invention comprise a method and system for producing etch points by control of breakdown process development. In one embodiment, at the beginning an applied laser radiation level just exceeds an energy threshold for creating a plasma condition in the material, and thereafter the energy level of the applied laser radiation is just maintain the plasma condition and is applied before the plasma condition extinguishes, but after a shock wave associated therewith has passed. Other embodiments of the invention comprise a method and a system for producing etch points by controlling a space structure of laser beam. According to the invention a laser generates a TEMmn radiation. The values of the integers m and n are controlled and determined so as to reproduce particular gray shades for a particular point of an image. Points or areas of laser-induced damage produced by these methods do have the traditional and undesirable star configuration. Furthermore, it is possible to control the brightness of these points without changing their size.

摘要:
A method of providing by a laser beam on a bright metal surface (1) areas discernible from the surrounding surface as darker areas for producing for instance optically readable marks (5) and a metal surface provided in this manner. The procedure for producing marks not weakening the general properties of the metal surface is that the metal surface (1) is exposed to a laser beam pulse, the energy of which is 1 to 10 J/cm.sup.2, preferably 3 to 5 J/cm.sup.2 and the duration 5 ns to 1 .mu.s, preferably 15 to 30 ns; a spot of impact (7) of the laser beam pulse on the metal surface (1) is changed in such a way that a new spot of impact (8) overlaps the earlier spot of impact (7) and the metal surface (1) is exposed to a new laser beam pulse, such that an area (7a) of the metal surface, where the pulses do not overlap each other and which abuts on the spot of impact of the new pulse, gets a color contrasting with the original metal surface (1).
