Patent number: 7128970Abstract: This invention is an indica transfer and method for its use to impart indica to polyolefin objects during rotational molding. The transfer is a laminate of at least two coats on a carrier sheet, which is preferably a flexible, transparent polymer sheet. The coats, as successive layers on the carrier sheet are: an indica coat of indica material in a graphic or alphanumerical array and a top coat of a top-coat pressure sensitive adhesive. Preferably the transfer also includes a backing coat of a backing-coat pressure sensitive adhesive between the carrier sheet and the indica coat, The pressure sensitive adhesive used for the top coat has a transition temperature less than the mold surface temperature onto which the transfer is applied to enable transfer of the coats to the interior surface of a rotational mold.Type: GrantFiled: May 22, 2001Date of Patent: October 31, 2006Inventors: Robert Alan Reeves, Michael J.

Patent number: 7112364Abstract: Foaming of a resinous backing (2) to a glass sheet (1) is frustrated at the interface (3) with the glass by maintaining the glass sheet (1) cool during formation of the foam. The degree of foaming is nil at the interface (3) to effect a strong bond there, and increases progressively through the thickness of the foam body (2) away from the interface (3). The foam body (2) is backed by glass-fibre cloth (4) that is impregnated with the resin from which the foaming gas has been vented so as to bond the cloth (4) to the body (2) and to an outer aluminium foil (5). The glass sheet (3) may be a mirror, and may be replaced by a glass laminate (20;23) that includes a fused-powder coating (22;25) with or without an aluminium foil backing.Type: GrantFiled: October 9, 2000Date of Patent: September 26, 2006Assignee: Thorstone Business Management LimitedInventor: Roger John Leach

Patent number: 7109134Abstract: A fusible quilt batt. The fusible batt includes a non-woven fibrous web and a heat sealable and releasable adhesive. The adhesive is coated on the outer surface of the web and insinuates between the fibers of the web internally. The adhesive thus binds the fibers of the web and provides a tackiness sufficient to allow the web to be applied to a backing material at an elevated temperature and removed from the backing at room temperature or an elevated temperature. After removal of the web from the backing material it may be reapplied to a backing material at an elevated temperature. The attachment, removal and reattachment process is repeatable.Type: GrantFiled: November 13, 2003Date of Patent: September 19, 2006Assignee: L&P Property Management CompanyInventor: Robert J. South

Patent number: 7091140Abstract: A nonwoven fabric comprises continuous polymer filaments of 0.5-3 denier that have been hydroentangled in a complex matrix of interconnecting filament loops, and that is otherwise substantially free of knotting, or of otherwise wrapping about one another. A process for making a non-woven fabric comprises continuously extruding polymer filaments of 0.5-3 denier onto a moving support, pre-entangling the filaments with water jets, and entangling filaments with a second set of water jets. An apparatus for making a nonwoven fabric comprises means for continuously extruding substantially endless polymer filaments of 0.5-3 denier onto a moving support to form an unbonded web, a pre entangling station for entangling the web with a plurality of water jets, and a plurality of water jets for final entanglement of the filament web.Type: GrantFiled: April 7, 1999Date of Patent: August 15, 2006Assignee: Polymer Group, Inc.Inventors: Rick Ferencz, Michael Putnam, Jian Weng
