Amorphous manganese oxide powder is grounded to a powder which is mixed with binder to form an electrode having a predetermined shape. The electrode reduces equivalent serial resistance and enhances high frequency characteristics since the contact area and the adhesion strength between the manganese oxide and the conductive carbon are improved. Also, the electrode has high capacitance suitable for a supercapacitor, which is manufactured therefrom at a greatly reduced cost.Type: GrantFiled: October 9, 2001Date of Patent: September 9, 2003Assignee: Ness Capacitor Co., Ltd.Inventors: Hee-young Lee, Heui-soo Kim, Woo-kyeong Seong, Sun-wook Kim

Publication number: 20030157297Abstract: A method for forming an article in which thermoplastics materials are used as the binding agent. Materials (21) are shredded in a shredder (1), compressed in a compressing chamber (15) and moulded in a moulding chamber (16, 17, 19, 20, 26, 27). The thermoplastics material is heated whilst the material is held under compression and then cooled to bind the material together. In one embodiment superheated steam is supplied via tubes (31) having apertures there along. In another embodiment superheated steam is supplied via apertures in side walls of the mould (58, 59). Blocks (62, 72) formed by the method and apparatus of the invention may find application as construction materials etc. and have good structural, thermal and acoustic properties.Type: ApplicationFiled: April 11, 2003Publication date: August 21, 2003Inventor: Peter Joseph Lelievre Lewis

Publication number: 20030141623Abstract: A method of making polymeric particulates wherein polymeric scrap material, virgin polymeric material and mixtures thereof are supplied to intermeshing extruder screws which are rotated to transport the polymeric material along their length and subject the polymeric material to solid state shear pulverization and in-situ polymer compatibilization, if two or more incompatible polymers are present. Uniform pulverized particulates are produced without addition of a compatibilizing agent. The pulverized particulates are directly melt processable (as powder feedstock) and surprisingly yield a substantially homogeneous light color product.Type: ApplicationFiled: October 23, 2002Publication date: July 31, 2003Inventor: Klementina Khait

Patent number: 6582545Abstract: The present invention is directed to the realization that the dimensions and basis weight of an electrode active admixture such as a transition metal oxide, and particularly silver vanadium oxide, formed into an electrode structure from an admixture paste subjected to a calendering process are influenced by the calender direction. To obtain electrode structures of a desired low basis weight requires a secondary calendering step performed in a direction reverse or orthogonal to that used to form the initial sheet tape. Orthogonal or reverse feed of the electrode active admixture provides for fibrillation of the fluoro-polymeric binder in other than the initial direction. This lets the binder spread in directions transverse to the initial direction to form the low basis weight electrode active structure.Type: GrantFiled: November 7, 2000Date of Patent: June 24, 2003Assignee: Wilson Greatbatch Ltd.Inventors: William C. Thiebolt, III, Douglas P. Eberhard, Jeffrey C. Grisante

Publication number: 20030085480Abstract: The invention relates to a method of producing an agglomerate of drug and solid binder. The process involves producing individual agglomerate particles and then converting the convertible amorphous content of same, following agglomeration, by the application of, for example, moisture. Agglomerates capable of conversion as well as the finished agglomerates and oral and nasal dosing systems including same are also contemplated. The process produces agglomerates which are rugged but which will produce an acceptable fine particle fraction during dosing.Type: ApplicationFiled: September 10, 2002Publication date: May 8, 2003Inventor: Tsong-Toh Yang

Patent number: 6555514Abstract: A multi-step process for making a granular detergent composition. The processing steps include adding to a first fluid bed dryer a first feed stream selected from a first powder, a first liquid, and mixtures thereof, to form a second feed stream. The second feed stream is added to a mixer to form a fourth feed stream, and optionally, a third feed stream selected from a second powder, a second liquid, and mixtures thereof can be added to the mixer. The fourth feed stream is added to a second fluid bed dryer to form the granular detergent composition. The granular detergent composition contains at least about 50% by weight of particles having a geometric mean particle diameter of from about 500 microns to about 1500 microns with a geometric standard deviation of from about 1 to about 2. Further, at least a portion of the particles contain a detersive surfactant or a detergent builder.Type: GrantFiled: April 24, 2001Date of Patent: April 29, 2003Assignee: The Procter & Gamble CompanyInventors: Scott William Capeci, Steven Matthew Gabriel, Girish Jagannath, Scott John Donoghue, Christopher Andrew Morrison
