Publication number: 20020099110Abstract: The present invention relates to radiation-curable compositions that after cure release fully from a matrix material while maintaining other desirable qualities of radiation-cured compositions. These radiation-curable compositions include at least one radiation-curable oligomer and at least one oligomeric photoinitiator. These compositions can be formulated, for example, to serve as protective coatings for substrates manufactured from a wide variety of including glass, plastic, ceramic, metal and wood. The compositions of the present invention are preferably designed for use as an optical fiber coating (including inner primary and, colored or uncolored, secondary coatings as well as other coatings which include inks, matrix materials and the like) or related optical fiber protective materials.Type: ApplicationFiled: December 30, 1999Publication date: July 25, 2002Inventors: TYSON NORLIN, JAMES J.

Patent number: 6413637Abstract: Metal cord for use in reinforcing fabric for articles made from rubber, such as pneumatic tires, conveyor belts, flexible tubes, and similar, comprising a plurality of such metal cords orientated parallel to each other in a single direction and in which each cord comprises metal wires wound spirally around each other, wherein at least one of the wires of the cord consists of a shape memory material. During the phase of incorporation of the cords into the elastomeric material, the shape memory wire tends to recover the shape memorized initially and, by means of the force generated during this recovery, transmits by friction to the surrounding wires forces tending to shorten the pitch of the cord with spacing of each wire from the next, resulting in good penetration of elastomeric material between the wires. The closure of the cord is maintained in the subsequent heat cycles, owing to the memory degradation characteristics imparted to the wire.Type: GrantFiled: April 2, 2001Date of Patent: July 2, 2002Assignee: Pirelli Coordinamento Pneumatici S.p.A.Inventors: Marco Cipparrone, Gurdev Orjela, Guido Riva

Patent number: 6399197Abstract: The object of the present invention is to provide a monofilament which has sufficient mechanical strength to be practically used also as a string for rackets and which is excellent in workability. Disclosed is a monofilament which is formed by extruding a material prepared by blending mainly a polylactic acid type polymer (A) and an aliphatic polyester (B) other than polylactic acid, and drawing the extruded material. This could be used as a racket string which has a tenacity-elongation curve similar to that of natural gut and is excellent in water resistance and heat resistance.Type: GrantFiled: April 26, 2000Date of Patent: June 4, 2002Assignees: Shimadzu Corporation, Gosen Co., Ltd.Inventors: Takeshi Kanamori, Hiroshi Urayama, Yoshiyuki Ohara, Tameyuki Nagano
