Patent number: 8741031Abstract: A composite hollow ceramic fiber includes a porous hollow core supporting a thin, dense sheath. The non-gas-tight core comprises a first ceramic material and an interconnecting network of pores. The gas-tight sheath comprises a second ceramic material. The fiber is made by extruding core and sheath suspensions from a spinnerette. The core suspension includes particles of the first ceramic material, a polymeric binder, a solvent, and a pore former material insoluble in the solvent. The sheath suspension includes particles of the second ceramic material, a polymeric binder and a solvent. The nascent hollow fiber is coagulated in a coagulant bath to effect phase inversion of the polymeric binders. The resultant green fiber is sintered in a two step process. First, the binders and pore former material are burned off. Second, the sheath is densified and the second ceramic material is sintered without fully sintering the core.Type: GrantFiled: July 31, 2011Date of Patent: June 3, 2014Assignee: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Madhava R.

Patent number: 8663513Abstract: Foam earplugs (90) are produced by extruding foamable material through a nozzle (12) having a throat (30) where the nozzle diameter is smallest, to produce an extrusion (34) that expands in diameter along an expansion zone (D) as the extrusion moves forward. Applicant moves dies (70, 72) against opposite sides of the extrusion and then moves the dies forward with the moving extrusion while the foam solidifies into earplugs. The earplugs to be formed have sealing portions that seal to a person's ear canal, of a maximum diameter G of about 0.4 inch, and the nozzle throat has a diameter B no more than 0.1 inch to provide a long expansion zone so the dies can begin to mold the extrusion while the extrusion is still expanding in diameter.Type: GrantFiled: August 7, 2007Date of Patent: March 4, 2014Assignee: Honeywell International Inc.Inventor: John Allen Jenkins, Jr.

Patent number: 8632706Abstract: A single-sided, slip resistant, self-adhesive material is produced using a blown film process which produces a film having an interior layer capable of being treated or coated to accept a pressure sensitive adhesive, a middle layer of flexible polyolefin and an exterior polyolefin elastomer layer in combination with a blowing agent to produce a single-sided slip resistant material. A number of in-line rollers are provided after a pair of rollers, which form part of a machine direction orienter (MDO) that is used in line in the manufacturing process to heat, and then cool and condition (anneal and relieve any stresses and/or thickness inconsistencies) the film prior to the film being coated on one side with a pressure sensitive adhesive.Type: GrantFiled: August 15, 2011Date of Patent: January 21, 2014Assignee: Multi Technologies Instustrial L.L.C.Inventors: George M. Orlych, Michael C. Sullivan, Thomas Zickell

Patent number: 8628848Abstract: A filmic label including a face material having a front side, a reverse side and an adhesive layer including pressure sensitive adhesive on the reverse side of the face material. The face material includes at least one surface layer on at least one side of at least one central layer. The at least one central layer includes cavities that have been initiated at initiation sites by stretching the face material in a longitudinal direction and in a cross direction. The cavities have been expanded in a thickness direction of the face material by allowing a gaseous substance to have an effect on the at least one central layer. Also a method for forming a plastic film for a filmic label.Type: GrantFiled: June 2, 2008Date of Patent: January 14, 2014Assignee: UPM Raflatac OyInventors: Håkan Saxen, Martti Vähälä, Tom Saxberg

Patent number: 8580898Abstract: The present invention relates to a copolymer polyester resin and a molded product using the same, and more specifically to a copolymer polyester resin that contains 10˜80 mol % of 1,4-cyclohexane dimethanol, 0.1˜50 mol % of a diol compound expressed as HO—(CH2)a—CO—(CH2)b—OH (where a and b are integers in the range 1˜5), and ethylene glycol or other diols so that the sum of its entire diol composition is 100 mol % based on dicarboxylic acid. The copolymer polyester resin of the present invention enables reduction of cycle time, improvement of product processability and prevention of PET bottle deformation during mold processing with a heat-shrinking label by complementing low temperature shrinkage, maintaining a high shrinkage rate, and reducing shrinkage stress.Type: GrantFiled: November 20, 2009Date of Patent: November 12, 2013Assignee: SK Chemicals Co., Ltd.Inventors: Myoung Ruoul Lee, Jong Ryang Kim
