  • Patent number: 5064692
    Abstract: A method and apparatus for producing a paper product having a surface with enhanced gloss. The method includes the following steps: Applying a continuous layer of an impressionable coating material to a paper product; contacting the layer of coating material with a polymer release film having a smooth and glossy surface substantially free of defects, the surface having non-adhering and release characteristics; and solidifying the coating material during contact with the release film. Using this technique, a smooth and glossy surface of the release film is substantially imparted to a surface of the layer of solidified coating material. In the case of clay-coated substrates, the coating is solidified by heating, whereas in the case of polyethylene-coated substrates, the coating is solidified by cooling. The end product is a coated substrate in which the coating has a glossy surface to which the texture of a film has been imparted.

  • Patent number: 5062582
    Abstract: An apparatus and method for manufacturing partially cut (semi-converted) products in continuous roll form has input feeds for supplying a continuous web of material and a continuous transport web in parallel, feed rollers for incrementally advancing the two webs together to a cutting station where product units are partially cut in successive increments in a continuous strip, a scrap remover, and a station for winding up the cut product strip. The webs are unwound and the cut product strip is wound via dancer bars maintaining constant tension. The input webs have a width which is a multiple of the width of the product units so that multiple strips can be formed simultaneously. The invention is used to form semi-converted, micro diskette liners having connecting portions and indented cutouts marking the boundaries between units. The cutouts are overcut in one direction and also in an intersecting direction to obtain complete cuts despite slight variations in registration.

  • Patent number: 5060105
    Abstract: A hybrid nonwoven liner for a diskete holder is bonded and impregnated with a small amount of binder which is uniformly distributed throughout the fabric and comprises no more than 5% by weight and preferably between 1.5-3.0% by weight of the fabric. The low concentration of binder ensures that the liner surface does not become totally coated with plastic film that reduces cleaning ability, while also providing a high increase in tensile strength and a significant debris reduction. The binder solution preferably has a high surface tension (low surfactant level), so that the binder beads and becomes dried at junction points of the fibers and evenly distributed throughout the fabric. The low level of surfactant ensures a low risk of chemical attack of the disk media surface.

  • Patent number: 5012959
    Abstract: A paperboard carton and plastic pour spout fitment construction for cartons adapted to carry powdered or granular material, particularly foodstuffs. A side wall of the carton is provided with a precut opening to receive the separate fitment. The periphery of the sides of the pour spout bottom wall must be broken from the surrounding fitment by the consumer upon initial use, to permit the spout to pivot for dispensing. The spout is thus held against accidental opening during shipping and handling prior to use, and further, such breaking is automatically tamper evident. The fitment is attached to a side wall of the carton by use of an adhesive or by a plurality of rivet stakes integral with the spout. The rivet stakes are received in complementary punctures bordering the precut opening. The use of plastic for the pour spout fitment insures against metal particles contaminating the contents of the carton.

  • Patent number: 5012750
    Abstract: An apparatus and method for recovering constituents and/or heat energy from a fluidized bed combustion process utilizes a single vessel which combines a combustor for fluidized bed combustion of a chemical mixture fed therein and a heat exchange section. Characteristics of the fluidized bed are controlled by withdrawing an appropriate portion of the larger, unburned constituent particles from the bottom of the combustor, and smaller constituent particles are withdrawn by becoming entrained within the gases of combustion and being transported to the heat exchange section. The smaller particles are separated from the gases without the use of a cyclone separator and accumulate as another fluidized bed in the heat exchange section where heat is adsorbed from the particles for recovery purposes and to cool the particles. A portion of the cooled particles is then recirculated to the combustor by, for example, pneumatic transport methods for controlling the operating temperature of the combustion process.
