Patent number: 7134387Abstract: A refrigerant gas is collected and a compressor is removed from a discarded refrigerator, a heat-insulating housing including a heat insulator is cut/processed and separated into a plurality of pieces, and the pieces are compressed/processed by compression rollers opposing each other so as to collect a gas contained in the heat insulator. In accordance with this method, substantially no gas contained in the heat insulator is diffused at the time of cutting the heat-insulating housing, and the gas can be collected at a high concentration because it is collected by being allowed to leak out at the time of compressing. Furthermore, by using the compression rollers, closed-cells in the heat insulator can be crushed easily, thereby collecting the gas completely and reliably. Thus, it is possible to collect a foaming gas contained in the heat insulator efficiently and disassemble a refrigerator at low cost without increasing the size of equipment and an installation space.Type: GrantFiled: July 12, 2001Date of Patent: November 14, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mikio Yotsumoto, Yutaka Matsuda, Takayuki Gyoubu, Katsuya Sawada

Patent number: 6588332Abstract: In a group of rolls for a calender for processing material webs, comprising at least two rolls each having a roll body made of a cast or forged iron material, at least one of the roll bodies consists of chilled cast iron or shell-chilled cast iron. One or more rolls may have a cover of a resilient material, such as a polymeric plastic. Although it is possible for the outer diameters of the rolls to differ, the sag of the rolls when they are supported only in their rolling-contact bearings is substantially equal. In order to produce appropriate rolls, following the essential machining steps of the roll bodies, that is to say, for example, following casting, following preliminary turning, following preliminary boring and, if appropriate, following the introduction of peripheral bores, the actual mean modulus of elasticity of the entire roll body is measured and, as a function of this, in particular the inner diameters of the central bores are produced.Type: GrantFiled: April 27, 2001Date of Patent: July 8, 2003Assignee: Schwabische Huttenwerke GmbHInventors: Heinz-Michael Zaoralek, Juergen Krueger, Bernd Eppli, Julien Tenelsen

Publication number: 20030010228Abstract: An embossing device for embossing a single-ply or multi-ply web of tissue paper includes a first steel roll with embossing protuberances on its peripheral surface and a second roll with a yielding layer on its peripheral surface. The second roll cooperates with the steel roll so as to form an embossing nip therewith. The steel roll and the second roll run in synchronization. The second roll has individual zones on its peripheral surface with a higher overall thickness and/or different material characteristics of the yielding layer compared to that of the remaining peripheral surface. These individual zones are opposed in the embossing nip to embossing protuberances of the steel roll.Type: ApplicationFiled: July 16, 2002Publication date: January 16, 2003Applicant: SCA HYGIENE PRODUCTS GMBHInventor: Bernd Lofink

Patent number: 6505658Abstract: A veneer dehydrating apparatus which has a pair of rotatable dehydrating roll assemblies disposed one above the other and having their axes extending parallel to each other, at least one of which is positively driven. The paired roll assemblies includes a first roll assembly having formed on the peripheral surface thereof a number of tooth-like projections extending radially outward from the peripheral surface and a second roll assembly having a steel core shaft which is clad with covering of elastic material such as urethane rubber with a predetermined thickness. The axes of the roll assemblies are a spaced radially to form a clearance or a nip between the peripheral surfaces thereof which is smaller than the thickness of the veneer sheet to be dehydrated.Type: GrantFiled: September 19, 2001Date of Patent: January 14, 2003Assignee: Meinan Machinery Works, Ltd.Inventor: Yoshinori Koba

Patent number: 6430459Abstract: A roll sensing system for measuring the pressure distribution and nip width in a nip roll press. The sensing system comprises a strip having sensors thereon, the strip being placed in a nip press, for sensing the pressure at several locations therealong. At one end of the strip lies electronics associated with the sensors. The electronics communicate with an optional multiplexer and a bidirectional transmitter for signal transmission to an external signal conditioner and an external computer. The computer determines pressure values and nip width values at various locations along the strip, and communicates with a display which provides a visual, graphical and/or numerical data to the operator. Optionally, a control system can be in communication with the transmitter or the computer to initiate crown corrections in response to pressure or nip width readings.Type: GrantFiled: March 19, 2001Date of Patent: August 6, 2002Assignee: SW Paper Inc.Inventor: Robert H. Moore

Patent number: 6422281Abstract: The application discloses an adhesive transfer apparatus comprising a frame, a first feed roll carrying a supply, of an adhesive transfer substrate, and a second feed roll carrying a supply of an adhesive mask substrate. The adhesive transfer substrate has a layer of pressure-sensitive adhesive disposed on an adhesive carrying side thereof. The first and second feed rolls are rotatably mounted to the frame. The adhesive mask substrate has a bonding side to which the adhesive will bond. Tie first and second feed rolls are positioned such that The selected substrate can be inserted between the transfer substrate and the mask substrate.Type: GrantFiled: May 5, 2000Date of Patent: July 23, 2002Assignee: Xyron, Inc.Inventors: Thomas C. Ensign, Jr., Joseph P. E. Velasquez, Jerry L. Hardy

Patent number: 6270612Abstract: A multi-purpose laminating and adhesive transfer apparatus having a frame supporting rotatably engaging nip rollers. A replaceable cartridge is insertable into the frame and has upper and lower feed rolls which may be a laminate, film or paper, or an adhesively coated film or a film having an affinity for adhesive. The upper and lower feed rolls containing the webs of laminating or adhesive transfer material have tensioning caps which can be adjusted to provide the proper tensioning to prevent the rollers from overrunning as they rotate. Tensioning caps and the cartridges are pre-set and provided to the user. A cutter blade is positioned at the discharge side of the nip rollers and may be actuated to sever the master at any desired location. The apparatus may be operated to apply lamination to either top or bottom surfaces of a substrate or an adhesive to the top or bottom surface of the substrate or to both surfaces.Type: GrantFiled: April 29, 1999Date of Patent: August 7, 2001Assignee: Xyron, Inc.Inventor: Franklin C.

Patent number: 6257133Abstract: A method and apparatus for obtaining a desired nip pressure distribution profile in the cross direction of a paper web. The paper web passes through a nip, the latter defined by at least one elastomer covered roll, the covered roll having polarizable particles or magnetic particles embedded therein. A plurality of spaced plates or spaced coils each generate a local field (respectively electric or magnetic) which acts upon individual spaced zones or regions along the covered roll. The field may thus be an electric field or a magnetic filed. The affect of the field is to change the effective modulus of the elastomer by acting on the particles. In turn, this action varies the nip pressure pulse as to exert a desired pressure at each of a plurality of spaced zones or regions on the paper web, to thus create or process a more uniform product in the nip. The method and apparatus can be used, for example, to improve web moisture profiles in the press section of paper machines.Type: GrantFiled: March 15, 1999Date of Patent: July 10, 2001Assignee: International PaperInventor: D.
