  • Publication number: 20030024628
    Abstract: A method of dimensioning a hooped tube intended to carry a fluid under pressure. The hooped tube consists of a metal tube and of a reinforcing element wound around the metal tube so as to hoop the tube. In a first stage, the method consists in determining, according to a first series of criteria, the characteristics of the metal tube without the hooping reinforcement that is wound around it at the end of the manufacture process. The first series of criteria includes the resistance to all the mechanical stresses applied to the hooped tube, i.e. compressive, bending, collapse and tensile stresses, with the exception of the radial stresses due to the internal pressure. In a second stage, the method consists in determining the hooping characteristics so as to obtain a determined prestress field in the wall of the hooped tube.

    Abstract: Processes for producing a holographic material involve producing the holographic image on a polished, substantially smooth surface and then transferring the holographic image to a substrate. A metallic coating is applied to a smooth surface of a printing element to provide a coated surface, the coated surface is embossed to provide the holographic image, and the holographic image is transferred to a substrate via a bonding material, thereby producing the holographic material. The holographic material may be used to provide a decorative cover for an object or item, such as a floral grouping or a potted plant.

  • Publication number: 20030024633
    Abstract: Disclosed is a radio frequency circuit having a membrane structure and manufacturing method for the same. The radio frequency circuit has a circuit element formed on an insulating material plate having copper bonded on both surfaces or one surface thereof whereby a metal substrate having a hollow bore and the insulating material plate forming the circuit element are bonded together. The circuit element is mounted with an active element on which a lid having a partition wall is bonded for packaging. The hollow bore in the metal substrate, for forming a membrane structure, is formed by press-blanking. Because the metal substrate is not wet-etched, dimensions control can be easily, precisely made on a hollow bore region of the metal substrate. Furthermore, it is possible to shorten the working time on the hollow bore region.

The fluororesin fiber paper is a porous sheet obtained by forming a slurry comprising fluororesin fiber into a sheet by a wet paper making method and sintering the resultant sheet and has an average pore diameter of 0.5 to 50 &mgr;m and a maximum pore diameter of at most 250 &mgr;m. A copper-clad laminate for printed board is produced by laminating the fluororesin fiber paper and a copper foil having a ten point mean height of surface roughness profile (Rz) of 0.5 to 8.0 &mgr;m on each other by means of vacuum hot pressing.

    Abstract: A manufacturing process for a two-layered facing 1 includes: a front material preparation step 11; a backing material preparation step 21; and a molding step 31. The backing material preparation step 21 includes the following steps: a papermaking step 22 in which short fibers and pulp material are blended and made into a paper, the paper is then coated with a binding agent and dried to obtain a paper sheet 4; and a winding step 23 in which the paper sheet 4 is cut into a tape-like form and rolled into a ring shape to obtain a backing molding material 5. In the molding step 31, the two-layered facing 1 is manufactured by laminating together a front material 2 manufactured in front material preparation step 11 and the backing molding material 5 manufactured in backing material preparation step 21 and thermally molding the two materials together while applying pressure.

    Abstract: The present invention uses hydrophobically modified polyaminamide with standard wet strength agent to produce a softer and more absorbent paper material. The hydrophobically modified polyaminamide is substantive to cellulosic fibers, thus is able to carry polyethylene glycol esters or ethers, a non-substantive material to cellulosic fiber as stable complexes, into the paper product.

  • Publication number: 20030024672
    Abstract: The invention relates to a method and arrangement for processing a wide paper or board web in connection with such a manufacturing method, in which a wide base web (14) is manufactured and the base web is processed in at least one processing stage before the separation of the finished product by cutting it transversely from the web on the production line. According to the invention, the base web (14) is divided at least once to form two part-webs (17, 18) before the separation of the finished product by cutting it transversely from the web and before the final processing stage preceding separation. At least one part-web (17, 18) formed in this manner is guided to a finishing stage before the separation of the finished product by cutting it transversely from the web on the production line.

  • Publication number: 20030024673
    Abstract: A process, and an apparatus, for improving sheet properties in the initial impingement zone of a paper making machine including a forming section, a forming fabric moving in the machine direction and a head box having a head box slice which delivers a stock jet onto the moving forming fabric. The scale and intensity of agitation within the stock is adjusted by adjusting some of the support elements beneath the forming fabric adjacent the head box slice so that they either contact, or do not contact, the machine side surface of the forming fabric and observing the effect, if any, that the adjustment has on the quality of the sheet product being made on the paper making machine. This technique is of use in a papermaking machine forming section having a single open surface forming fabric, in the initial open surface section of a so-called hybrid gap former having two superposed forming fabrics, and in the forming section of a two fabric papermaking machine.

    Abstract: A web of tissue is formed in a twin wire former, followed by an air press for water removal in the pressing section, passing onto a Yankee dryer. A headbox injects stock between upper and lower dryer fabrics brought together on a breast roll. The fabrics move over vacuum boxes, and the web is heated with steam and passed between an upper pressure box and a lower vacuum box forming an air press which dewaters the web. A sheet transfer pickup vacuum box holds the sheet to the upper fabric as the lower fabric diverges from the upper fabric. A pressure roller transfers the web onto a Yankee dryer. The fabrics are cleaned on vertical runs before returning to the breast roll.

    Abstract: To address the conflict between structural strength and flexibility in a conventional elastic belt for a papermaking calender, and to reduce manufacturing time, a belt in which the paper sheet-facing side of a base body side is covered by a high molecular weight elastic layer, is characterized in that the high molecular weight elastic layer is composed of a dense, first high molecular weight elastic layer and a second, high molecular weight elastic layer having a multitude of small voids of almost the same size. Flexibility of the layer having small voids is achieved while the dense surface layer is adapted to the ruggedness of the paper sheet.

    Abstract: The invention relates to a press roll (1) comprising a flexible rotating endless-loop blanket (3) of a liquid-impervious material, two disc-shaped roll heads (4, 5), and a clamp element (14) filled with a pressurized medium for clamping the lateral rims (21) of the blanket (3) to the respective ones (4, 5) of the roll heads. The invention is implemented by adapting between the pressurized-medium-filled clamp element (14) and the blanket (3) an annular ring (18) serving to press the rim of the blanket (3) during the pressurization of said clamp element against the inner rim surface (15) of a sector plate (7) and, respectively, serving to contract the clamp element (14) when the pressure of the clamp element (14) is removed or lowered.
