Publication number: 20080174110Abstract: An abrasive material transferring pipe is lined with a cured shape memory retaining elastomeric liner. The inner surface of the pipe is in contact with the outer surface of the elastomeric liner. When the liner is not under tension, the outer diameter of the elastomeric liner is larger than the inner diameter of the pipe. Expansion pressure by the liner maintains the liner in the pipe.Type: ApplicationFiled: January 16, 2008Publication date: July 24, 2008Inventor: John Frederick Olson

Publication number: 20080093337Abstract: The invention is a method of bonding a first fluid conduit (14) to one or more other fluid conduits (12) or elements such as an electrode (92) or heating element. The method comprises positioning a first fluid conduit (14) substantially in contact with the other fluid conduits or elements (12) wherein a bond region (16) is created. The bond region is wetted with a liquefied thermoplastic polymer (34) which is then subsequently cooled forming a substantially fluid tight bond between the first fluid conduit (14) and the other fluid conduits or elements (14).Type: ApplicationFiled: July 16, 2004Publication date: April 24, 2008Applicant: WATERS INVESTMENTS LIMITEDInventors: Theodore Dourdeville, Dennis DellaRovere

Patent number: 7329444Abstract: The invention is a composite pole with an integral mandrel therein and methods of making the same. A preferred embodiment is a fiberglass reinforced resin composite pole such as a utility pole or a lighting pole. The integral mandrel is preferably an expanded plastic foam such as expanded polystyrene. The integral mandrel is contoured to be in the desired inside configuration of the composite pole and fiber reinforced composite naterial is applied to the mandrel. The pole is used with the mandrel remaining therein, thus strengthening the pole. Passages may be placed into the mandrel for routing conduits and pipes as desired.Type: GrantFiled: May 12, 2003Date of Patent: February 12, 2008Assignee: Pomm Plastics, CoInventors: Yosef D. Boaz, Michael Boynoff, Paul Cherkas

Patent number: 7309175Abstract: Method and apparatus for mounting an optical fiber for coupling to a high power light source, the fiber being secured to its mount with a low refractive index adhesive. The low refractive index adhesive serves to reduce the coupling of light traveling within the fiber to the fiber mount, thereby reducing undesirable, potentially destructive heating in the fiber mount. The adhesive preferably comprises sol gel.Type: GrantFiled: July 28, 2006Date of Patent: December 18, 2007Assignee: EM4, Inc.Inventors: Alex Rosiewicz, Ninghui Zhu, Michio Matsuki

Patent number: 7264279Abstract: A conduit (100) comprising a plurality of conduit segments (112A–112C) each having a body (120A–120C) and a segment lining (136A–136C) made of a lining material. Each body includes a joint face (132A–132C) having secured thereto a portion (140A–140C) of the corresponding segment lining. A monolithic lining (108) is formed from the segment linings by abutting the conduit segments with one another so that the joint faces face one another and the portions of the segment linings contact one another. The portions of the lining on the joint faces are heated to a temperature above the melting point of the lining material so that they fuse with one another so as to form a fusion (148A, 148B) located between the joint faces.Type: GrantFiled: July 8, 2004Date of Patent: September 4, 2007Assignee: Fab-Tech, Inc.Inventors: Joseph M.
