  • Publication number: 20070231514
    Abstract: A release sheet for transferring a graphic onto an associated object includes a carrier film formed from a flexible polymeric material having melting point greater than about 150° C., a release layer disposed on the carrier film that is applied to the film in a solvent solution non-degradating to the carrier film, a transfer layer disposed on the release layer that is applied to the release layer in a solution non-degradating to the release layer and a graphic disposed on the transfer layer in a form that is non-degradating to the transfer layer. The release sheet containing the graphic is formulated for application to an associated object that is cured or vulcanized at an elevated temperature and humidity, such that the graphic transfers to the object during vulcanization or curing and the carrier film and release layer are removable from the object following vulcanization or curing.

  • Patent number: 7021549
    Abstract: A laser markable heat transfer label for application to an item includes a light transmissive carrier, a heat transferable substrate disposed on the carrier and an adhesive disposed on the substrate. The substrate is formulated, at least in part, with a laser light alterable material. A variable graphic component is marked on the label by application of a laser light through the light transmissive carrier, into the substrate to alter the laser light alterable material. The variable graphic component is marked prior to application of the heat transfer label to the item. A method of making and a method of using the laser markable labels are also disclosed.

  • Patent number: 5352507
    Abstract: A novel multilayered sleeve-like printing blanket is mountable on gapless cylinders or tubular blanket carriers, thereby minimizing vibration when operated at high rotational speeds. An exemplary printing blanket comprises a seamless outer printing surface layer; at least one reinforced elastomer layer, the elastomer layer being reinforced by fibers substantially parallel with the inward and outward sides of the cylindrical tube defined by the reinforced elastomer layer; and a resiliently compressible layer. The oriented fibers reinforce the elastomer layer such that the modulus of elasticity in the circumferential direction of rotation is increased. Exemplary methods for forming one or more of the layers are also disclosed herein.

  • Patent number: 4981750
    Abstract: A printing blanket having excellent lateral stability comprised of a carcass formed of one or more layers of woven fabric with low machine direction elongation characteristics, a nonwoven fabric attached to an upper surface of the lower most woven fabric layer, a compressible layer secured to the upper surface of the carcass and an ink transfer layer imposed upon the upper surface of the compressible layer. The blanket having a carcass containing a nonwoven layer comprised of continuous or discontinuous filaments, displays excellent cross machine direction elongation stability.

  • Patent number: 4812357
    Abstract: A printing blanket having excellent dimensional stability, compressibility and web feed properties comprising a carcass, a compressible layer overlaying the carcass, a stabilizing layer of thermoplastic reinforced elastomer overlying the compressible layer and a printing surface layer of void free rubber. The thermoplastic reinforced elastomer is formed of fibers or fibriles of thermoplastic dispersed throughout the elastomer. Preferably the thermoplastic is molten when mixed with the elastomer in order to provide very fine, well dispersed fibriles.

  • Patent number: 4369236
    Abstract: The instant invention is directed to a sheet product capable of forming an improved battery separator. The present sheet product is formed from a thin, acid-stable, porous material and has a first and a second major face with a plurality of separate, continuous, open channels on each major face such that each channel on each major face defines a separation between two channels on the other major face. Further, each channel defines an imaginary median line with at least some portions of at least some channels extending laterally with respect to the imaginary median line and each channel has at least one continuous contour line in the form of straight line segments such that every portion of each channel is capable of being at an acute angle of not greater than 70 degrees from an imaginary vertical line orientated from bottom to top of a battery containing the sheet product.

  • Patent number: 4330602
    Abstract: A battery separator useful in alkaline battery systems, and a process of forming the same, is formed from a composition having 30-70% by weight synthetic pulp, 15-65% by weight alkali resistant inorganic filler, and 1-35% by weight of long fibers having lengths of between 1/4 and 1 inch. The long fibers may be polyester, polyacrylic, polyamide, polyolefin, or other staple fiber material. The process for forming the subject battery separator requires first forming a substantially uniform aqueous mixture of the subject composition, sequentially treating said composition with a combination of a cationic and an anionic agent, applying the treated composition to a standard paper-making apparatus at a grammage rate to cause the resultant dried sheet to have a thickness of less than about 10 mils, and forming a sheet product.

  • Patent number: 4265985
    Abstract: A battery separator is provided that has 30-70% polyolefin synthetic pulp, 15-65% siliceous filler and 1-35% by weight of long fibers having lengths of between 1/4 and 1 inch. The long fibers may be polyester fibers or glass fibers or a mixture. Cellulose may be included in an amount up to about 10%.A process for forming the battery separator is also revealed using standard paper making equipment but employing ionic copolymers containing acrylamide in cationic and anionic combination to give good affinity of the siliceous material and polyolefin. Alum and other processing aids are also included as are other procedural steps such as pressing the web.

  • Patent number: 4264691
    Abstract: A battery interseparator useful in alkaline battery systems, and a process of forming the same, is formed from a composition having 30-70% by weight synthetic pulp, 15-65% by weight alkali resistant inorganic filler, and 1-35% by weight of long fibers having lengths of between 1/4 and 1 inch.

  • Patent number: 4228225
    Abstract: A battery separator embossed with a configuration that is neither vertical corrugation or vertical rib and yet in which all of the surface areas of the two separator faces open or slant upwardly except the portions actually directly engaged against a battery plate. Thus all intended recesses in the faces of the battery separator are open at their upper extremity so that no gas can be trapped by the configuration of the battery separator embossment. Additionally the division portions between the embossed recesses on the positive plate engaging face are in continuous engagement with the positive battery plate from the bottom of the plate to the top of the plate which provides stability to the raised areas of the battery separator that engage the negative battery plate.

  • Patent number: H440
    Abstract: A blanket bar assembly for use on a printing blanket comprising a U-shaped bar having a centrally located channel and two arms extending outwardly from the channel in a substantially parallel relationship. Inwardly directed projections are provided on one or both arms and are directly aligned with holes on the opposite arm or arms. The projections are of such a length so as to be capable of extending through the holes and be deformed so as to lock the arms together. A printing blanket edge inserted into the channel and pierced by the projections is thereby securely fastened to the blanket bar.
