  • Patent number: 6341421
    Abstract: Metal powder is filled in a through-hole of a base member and a base porous body is formed by bonding the metal powder with each other and by bonding the metal powder to the base member so that an end surface on a bearing surface of the metal powder filled in the through hole is dented toward a compressed gas supply surface and at least a part of end surface on the compressed gas supply surface of the metal powder filled in the through-hole is dented toward the bearing surface. Subsequently, surface layer powder having smaller diameter than the metal powder is filled in the recess on the bearing surface to form a surface layer porous material layer by bonding the surface layer powder with each other and by bonding the surface layer powder to the base porous body 12 and the base member 10. The bearing surface is finished by removing face layer of the surface porous material layer by machining.

  • Patent number: 6328681
    Abstract: The industrial roll of the present invention comprises a substantially cylindrical core, an adhesive layer overlying the core, and a cover overlying the adhesive layer. The cover comprises: a polymeric base layer overlying the adhesive layer; and a top stock layer overlying the base layer. The top stock layer comprises a mixture of an elastomeric material and ultra high molecular weight polyethylene (UHMWPE), with the mixture including 100 parts elastomeric material by weight and between about 25 and 50 parts UHMWPE by weight. With these components in the recited ratios, the roll can be formulated to a desired hardness within the desired 10 to 50 P&J hardness range while maintaining release properties suitable for papermaking in the papermaking environment.

  • Patent number: 6316061
    Abstract: A half bearing has a backing member and at least one metallic overlay, which is applied by electron beam vapour deposition and which comprises at least one finely dispersed component in a matrix material, the atomic weight of which component is greater than that of the matrix material, wherein the concentration of the finely dispersed component (7) decreases continuously from the apex area (8) of the half bearing (1) towards the area (9) of the partial surfaces. The method is characterised in that, during the coating process, an inert gas pressure of 0.1 to 5 Pa is set in the apex area of the bearing shell.

  • Patent number: 6298538
    Abstract: A nonwoven, metal fabric is formed by providing a mass of loose fibers with sufficient lubricating oil for them to be carded without disintegration of the fiber web. The fiber web is then lapped and needled to form a metal fabric of superior strength, density, and thermal insulation properties.

  • Patent number: 6290633
    Abstract: A damping roller for printing presses and a method for the production thereof, wherein a heat injected microporous special steel coating is applied to a cylindrical base body, is described. The average pore body of said coating is approximately 5 &mgr;m. A thicker moistening agent film is obtained by capillary force thereby enabling a higher moistening agent flow rate in the damping system of an off-set printing press.

  • Patent number: 6289590
    Abstract: A method of forming a bearing includes adding at least one particulate material to an aqueous dispersion of polytetrafluoroethylene, mixing the constituents to allow the polytetrafluoroethylene to coagulate to form a mush, spreading the mush on to a support, and curing the mush to form a bearing lining layer on the support. The method is characterized in that the partiulate material is in the form of an aqueous colloidal dispersion including small particles and in that the small particles of the particulate material itself cause coagulation of the polytetrafluoroethylene without need for an additional separate coagulant material.

  • Patent number: 6289588
    Abstract: The process serves to manufacture textile-processing devices such as card cylinders of ring-shaped configuration that comprise an all-steel wire clothing, or circular combs that are fitted with outward-facing saw-toothed wire sections. The wires (3) or the wire sections (13) are pre-bent to conform to the curvature of the ring (1) or circular comb mounting support (12), then surface-hardened through the application of a diamond/Ni layer, and finally anchored on the ring or circular comb mounting support.

  • Patent number: 5465483
    Abstract: A method of removing a metal plug from a conduit includes the steps of simultaneously applying a static pull force and repetitive impulses to the plug. The method is particularly suited to removing a plug from a heat exchanger tube in a nuclear powered steam generator. A tool for practicing the method on such plugs includes a first hydraulic actuator for first moving an expansion member out of engagement with an interior plug wall, a second hydraulic actuator capable of attachment to the plug for applying a static pull force to the plug, and an arrangement connecting an air impact tool to the second hydraulic actuator for applying, simultaneously with the static force, high-frequency impulses to the plug entirely through solid members.

  • Patent number: 5437087
    Abstract: A method for attaching an interduct to a duct by forming a groove on an outer surface of the duct and pressing out that portion of the duct encompassed by the groove to form an opening in the duct. A saddle is then attached to the duct and the interduct the attached to the saddle. The apparatus used for forming the opening in a duct comprises a template having an arcuate portion with a radius substantially the same as the duct. The template has a window portion having substantially the same shape as the opening to be formed in the duct. A base plate is provided having an arcuate portion with a radius substantially the same as the radius of the arcuate portion of the template such that the base plate is slidably fittable over the template. A cutting device is attached to the base plate and has a cutting element extending through the base plate.
