  • Patent number: 4606264
    Abstract: A web of paper or similar material is subjected to at least one nip formed by an iron roll and a compliant roll. The iron roll is heated to a temperature of at least the temperature at which the fibers in the web begin to deform. In the case of paper this is approximately 350.degree. F. Preferably the web is passed through two nips the first nip polishing one side of the web, the second nip polishing the other side. The result is a web having improved gloss without substantial loss of bulk and with minimum mottling.

  • Patent number: 4602895
    Abstract: An off-shore drilling platform or the like supported by support legs standing on the bottom of the sea is converted to withstand ice pressure occurring in ice filled waters by providing those portions of said drilling platform, which are to be protected against ice pressure, with protective structures below the platform. The drilling platform and/or the protective structures are then, when ice occurs, lowered along the support legs to a level where the protective structures partly extend below the surface of the ambient water.

  • Patent number: 4601435
    Abstract: In an arrangement for forming rolls from a running web, the web is slit in its longitudinal direction and wound into a plurality of rolls, all having the same rotation direction during winding. The arrangement comprises means providing a peripheral as well as a central roll support force acting on the rolls during winding. The arrangement is so dimensioned that, due to the increase of the roll diameter during winding, the ratio of the peripheral support force and the central support force of a roll undergoes a substantial change merely as a result of the geometrical construction features of the arrangement. In the final phase of the winding of a roll, the central support force of the roll is considerably higher than the peripheral support force of the roll.

  • Patent number: 4601441
    Abstract: An arrangement for winding a web on a roll core or the like in a support drum winder, which comprises a first and a second support drum, a web cutter, transfer means for the transfer of a complete wound roll from said support drums, supply means for the supply of a new roll core and guide and retainer devices for governing a web trail end and a front end formed by an engagement of the cutter with the web. The governing is carried out until a supplied core retains said web front end against the first support drum. The arrangement comprises means for a free new core supply from a location above the support drums in a position therebetween. The supply is carried out preferably by the free fall action and during the transfer of the complete roll. The retainer devices comprise retainer members separate from the first drum. These retainer members generate a force action against said first support drum.

  • Patent number: 4598877
    Abstract: Apparatus for winding web material, such as a paper web, on a tubular core to obtain a web roll includes a first carrier roll forming a first nip with the web roll, a second carrier roll forming a second nip with the web roll, at least one of the first and second carrier rolls being driven to rotate the tubular core and web roll being wound thereon, and a weight roll acting on the web roll with a press force. The first and second carrier rolls and weight roll are arranged asymmetrically with respect to each other such that the weight of the web roll acts on the second nip and the tension of the web material being wound is determined by the magnitude of the component of the press force applied by the weight roll acting on the first nip. The web material is disposed to run onto the core tube through a space between the first and second carrier rolls and through the first nip.

  • Patent number: 4596291
    Abstract: A floating semisubmersible off-shore drilling platform or the like comprises an upper working level portion and a lower pontoon portion. When the platform is transported from one place to another, it floats on the pontoon portion, but when it is working as a stationary unit in open water, it is submerged deeper, so that the pontoon portion is at a considerable distance below the water surface and the working level portion is at a considerable distance above the water surface. The platform is adapted to withstand ice pressure from ice occurring in the ambient water by giving the pontoon portion of the platform a form particularly advantageous in ice conditions. When ice occurs, the platform is lifted to such a position, that its pontoon portion comes to float at the water surface level.
