  • Patent number: 5633116
    Abstract: A prepress color proof can be prepared using suitable donor elements and an intermediate receiver element that has a roughened outer image receiving layer so that the color image is transferred with high image resolution. The intermediate receiver element can also have a cushioning layer beneath the outer image receiving layer that reduces the tendency for entrapped dirt particles to form minus density spot defects. In addition, a unique carrier plate can be used to carry the donor and intermediate receiver elements through laminating equipment. This carrier plate has a thermoplastic adhesive layer with sufficient tackiness to prevent irreversible dimensional change during lamination.

  • Patent number: 5573631
    Abstract: A laminating system for bonding, to receiver stock, a lamination sheet of the type including a carrier and a material to be applied to the receiver stock, and for subsequently de-laminating the carrier from the receiver stock after the material has been applied to the receiver stock, includes a fuser to apply the material to the receiver stock. The leading edge of the carrier has a de-lamination leader to separate the carrier from the receiver stock as the leading edge of the sandwich emerges from the fuser. A first portion of the carrier is manually directed through a pair of idler rollers as the sandwich emerges from the fuser to form the carrier into a generally S-shaped curve so that operator attention is thereafter not needed to separate the remainder of the carrier and receiver stock.

  • Patent number: 5441368
    Abstract: An anti-fouling apparatus and method for retarding the formation of marine plants and animals on marine surfaces submerged in water is disclosed. Telescopically extendable support arm members in the form of pneumatic struts are pivotally mounted on a mounting bracket for selective movement between a first raised position, at which the distal end is raised out of the water, and a second lowered position, at which the distal end is submerged in the water. A selectively energizable water propulsion means, which includes an electrically powered motor and a propeller, is operatively mounted on the support arm member adjacent to the distal end so as to be submerged in the water when the support arm is in the second lowered position.
