  • Publication number: 20010014390
    Abstract: A method for fabricating an object to attenuate thermal sensation when handling the object at non-body temperature, and an object fabricated in accord with the method. There is first provided a substrate which has a first surface subject to handling. There is then formed upon the first surface of the substrate a coating. The coating has an optimal density, an optimal thermal conductivity and an optimal thickness such that when the substrate having the coating formed thereupon is equilibrated at a non-body temperature differing from a body temperature and the coating is subsequently contacted with a body at the body temperature during handling, the temperature of the surface of the coating at a contact point of the body with the coating changes precipitously to a temperature near the body temperature and subsequently returns towards the non-body temperature at a rate which permits handling of the coating at the location of the first surface of the substrate by the body with attenuated thermal sensation.

  • Patent number: 6159569
    Abstract: A decal organization tool for products needing large numbers of decals utilizes a single large sheet on which all product decals for a specific product or product model are carried. The invention includes a means by which the previously unavoidable irregular margins surrounding the decals are effectively hidden from the eye and allows large sheet printing of decals with an aesthetically satisfactory overall appearance. An irregularly zone is added to the edge of each decal, and along with an ultraviolet responsive additive placed in the decal adhesive, allows the decal to form an indelible footprint on the product to which it is applied. The footprint, invisible to the eye, becomes visible under ultraviolet light, allowing identification of a specific decal and proof of its application to a product, even when the decal is no longer on the product.

  • Patent number: 6139932
    Abstract: There is disclosed a roll of a pressure sensitive adhesive-backed linerless label web with lines of perforation cuts comprised of alternating cuts and ties. The tie at each side margin of the web is weaker than the next adjacent tie to prevent winging up of tabs at the side margins of the web during unwinding of the roll and/or during feeding of the web through a printer, and yet the cuts in the side margins facilitate the initiation of tearing of labels from the web when desired but the weak ties are easy to tear manually and do not substantially impede such initiation of manually tearing.
