Patent number: 6699354Abstract: The gluing together of flat materials between belt faces (21, 22), facing one another, of belt conveyors (15, 16) arranged over one another is effected usually with the application of heat and pressure. However there are pressure sensitive materials that with the gluing may only be impinged with a slight pressure. Here already the weight of the sagging belt face (21) of the upper belt conveyor may lead to an excessive pressure loading and a permanent deformation of the materials caused by way of this. The invention solves the mentioned problem in that the upper belt face (21) located above the materials to be glued is held up without contact, e.g., by means of suction nozzles or magnets. The sagging of the belt face (21) is alleviated by way of this and an undesirable high pressure loading of the materials to be glued is avoided. By way of the contactless holding-up of the belt face (21) the suction nozzles or magnets do not interfere.Type: GrantFiled: May 24, 2001Date of Patent: March 2, 2004Assignee: Schaetti AGInventors: Peter Schwenk, Wilfried Dreischmeier

Patent number: 6699363Abstract: A process that can be used for producing a starch product is provided. The process comprises heating a composition, which comprises or consists essentially of a starch, a polyacrylamide, and a multivalent cation. The weight ratio of starch to polyacrylamide is greater than about 2 to 1. The process can also comprise heating a composition, which comprises or consists essentially of a starch and a polyacrylamide to produce a heated composition followed by contacting the heated composition with a multivalent cation. The heating can be carried out at a pH above 7.0 if the polyacrylamide is a cationic polyacrylamide or nonionic polyacrylamide and, if the starch is a cationic starch and the polyacrylamide is an amphoteric polyacrylamide or anionic polyacrylamide, the heating neutralizes less than 75% of the cationic starch.Type: GrantFiled: November 13, 2001Date of Patent: March 2, 2004Assignee: E. I. du Pont de Nemours and CompanyInventor: Robert Harvey Moffett

Patent number: 6699364Abstract: An improved method and apparatus for imparting a smooth surface to gypsum fiber panels. The method involves imparting energy to the surface of a slurry as the slurry is dewatered just prior to rehydration. The apparatus used to impart the energy is a water spray including a source of pressurized water such as a pump, a distribution manifold and a plurality of nozzles to direct the water spray at the surface of the slurry. In operation, the water spray is directed against the surface of the slurry. The flow disrupts the slurry to a fraction of its total depth, thus dispersing clumps or flocs of commingled crystals and fibers in the depth that would give the surface of the finished panel a rough surface if they were allowed to remain.Type: GrantFiled: October 31, 2002Date of Patent: March 2, 2004Assignee: United States Gypsum CorporationInventors: Weixin Song, David Paul Miller

Patent number: 6699365Abstract: This invention relates to a three-stream atomizing nozzle for use with a rewet shower. The nozzle has an air stream divider that separates the atomizing air from the source into three streams. The first stream is a straight air stream staying closest to and around the atomized water jet. The second stream is a swirl running around the first straight stream. The third stream is also a straight stream that wraps around the first straight stream and the second swirl. The nozzle also has a mixing chamber in which the three air streams are mixed together for the atomizing purpose. The nozzle can from the combination of the three air streams produce fine water droplets that are suitable for a paper rewet shower and more importantly creates a tailorable water mass profile. The mass profile can be tailored into a shape that is close to a square shape which is ideal for rewet showers as a square profile creates minimal coupling between adjacent zones.Type: GrantFiled: October 22, 2001Date of Patent: March 2, 2004Assignee: ABB Inc.Inventor: Shizhong Duan

Patent number: 6699366Abstract: A press fabric for the press section of a paper machine has a base fabric which includes a nonwoven mesh fabric. The base fabric, or a layer thereof, is assembled in integral form using a strip or strips of the nonwoven mesh fabric. The assembly may be effected by spirally winding the nonwoven mesh fabric in a plurality of non-overlapping turns, by abutting each turn of the nonwoven mesh fabric against that previously wound, and by joining each turn of the nonwoven mesh fabric to that previously wound to form an endless loop. Alternatively, a plurality of endless loops of equivalent length are formed from separate strips of nonwoven mesh fabric, and arranged in a side-by-side abutting relationship. The endless loops are then joined, one to the next, to provide a base fabric, or component thereof, in the form of an endless loop.Type: GrantFiled: April 24, 2001Date of Patent: March 2, 2004Assignee: Albany International Corp.Inventors: Maurice R. Paquin, James G. Donovan

Patent number: 6699368Abstract: To improve the water squeezing function of a shoe press belt for papermaking, the wet web side layer of a main body of the belt is composed of a high molecular weight elastic material, and the wet web facing surface of the wet web side layer is made hydrophobic. Water, squeezed from the wet web under compression in a shoe press, and transferred to the surface of the wet web side layer of the belt through a felt, may be shaken off reliably before the belt is again subjected to compression.Type: GrantFiled: December 27, 2001Date of Patent: March 2, 2004Assignee: Ichikawa Co., Ltd.Inventors: Hirofumi Ishii, Nobuyuki Ito, Kazumasa Watanabe

Patent number: 6699369Abstract: A method for removing dissolved solids, particularly salts, from water. An apparatus for performing the inventive method is disclosed. The aqueous solution to be treated, for example sea water, is atomized using special non-pneumatic nozzles, and sprayed into an evaporation chamber through which air, heated by waste heat, is blown. The micro-droplets undergo rapid evaporation in the chamber, resulting in the separation of the salt solids from the vapor phase of the water. The mixture of suspended solids and water vapor is filtered to remove and collect the salts, and the water vapor is condensed to collect the salt-free water.Type: GrantFiled: August 10, 2001Date of Patent: March 2, 2004Assignee: Aquasonics InternationalInventors: William Francis Hartman, Larry Joe Kepley, Jerry Van Fox

Patent number: 6699370Abstract: In a process for decomposing pollutants by bringing pollutants contained in air into contact with air that contains chlorine, under irradiation by light, at least part of a chlorine-generating solution present in a chlorine generation region is fed to a means for forming the functional water by electrolysis to effect regeneration and is again fed to the chlorine generation region. Also disclosed is a pollutant decomposition system used in such a process.Type: GrantFiled: June 15, 2001Date of Patent: March 2, 2004Assignee: Canon Kabushiki KaishaInventors: Akira Kuriyama, Kinya Kato, Masahiro Kawaguchi
