Patent number: 7294686Abstract: Hematin, a hydroxyferriprotoporphyrin, is derivatized with one or more non-proteinaceous amphipathic groups. The derivatized hematin can serve as a mimic of horseradish peroxidase in polymerizing aromatic monomers, such as aromatic compounds. These derivatized hematins can also be used as catalysts in polymerizing aromatic monomers, and can exhibit significantly greater catalytic activity than underivatized hematin in acidic solutions. In one embodiment, polymerization is in the presence of a template, along which aromatic monomers align. An assembled hematin includes alternating layers of hematin and a polyelectrolyte, which are deposited on an electrically charged substrate. Assembled hematin can also be used to polymerize aromatic monomers.Type: GrantFiled: January 23, 2006Date of Patent: November 13, 2007Assignees: University of Massachusetts Lowell, United States of America as Represented by the Secretary of the ArmyInventors: Susan Tripathy, legal representative, Lynne A.

Publication number: 20060170292Abstract: Disclosed is a stator of reciprocating motor comprising: a stator including two lamination assemblies formed accordingly as a plurality of lamination sheets are stacked as a cylindrical shape or a circular are shape; and a mover inserted into an air gap between said two lamination assemblies and linearly reciprocating. In the stator, the lamination sheets constituting the lamination assembly are thicker at an outer circumference side of the lamination assembly than at an inner circumference said thereof. According to this, a path of a flux applied to the lamination assembly is maximized thus to minimize a resistance of the flux.Type: ApplicationFiled: March 11, 2004Publication date: August 3, 2006Inventor: Bon-Cheol Ku

Patent number: 7056106Abstract: A discharge valve apparatus for a reciprocating compressor comprises a discharge cover having built-in volume so as to cover a front end surface of the cylinder; a discharge valve disposed so as to be contacted/separated to/from the front end surface of the cylinder by a piston which undergoes a reciprocating movement inside the cylinder; and a valve spring having both ends respectively adhered to rear side of the discharge valve and to inner surface of the discharge cover so as to elastically support the rear side of the discharge valve. A rotation radius of the valve spring of a conical type is formed to be gradually reduced or increased so that impacts of a part to other parts during the compression can be prevented. Accordingly, when the valve spring is compressed in accordance with the compression and discharge strokes of the piston, the impacting noise caused by the impacts of the respective parts in the valve spring can be prevented previously.Type: GrantFiled: May 19, 2001Date of Patent: June 6, 2006Assignee: LG Electronics Inc.Inventors: Hyuk Lee, Jung-Sik Park, Gye-Young Song, Bon-Cheol Ku

Patent number: 6913450Abstract: A suction valve coupling structure for a reciprocating compressor is disclosed in which a piston being linearly moved in a cylinder upon receipt of driving force from an electric mechanism unit, according to which gas flows through a gas flow passage formed therein, is coupled by welding to a valve for opening and closing the gas flow passage, thereby strengthening the coupling state of the suction valve. Since the coupling structure is simplified, a dead volume is reduced and a stroke volume is increased, improving compression efficiency. A stroke control of the piston is facilitated to enable a precise control of movement of the piston. In addition, a reliability of the coupling of the suction valve can be improved.Type: GrantFiled: June 26, 2001Date of Patent: July 5, 2005Assignee: LG Electronics, Inc.Inventors: Seong-Joon Hong, Bon-Cheol Ku, Hyeong-Suk Kim, Hyung-Pyo Yoon
