  • Patent number: 5012767
    Abstract: Pendant superheater or reheater tubes are maintained in spaced relationship by pairs of collar elements joined together in a closely adjacent relationship. One of the collar elements is dimensioned allow for vertical movement of the tube over which it is fitted throughout the range of temperatures to which the tubes are exposed. The other collar is mechanically fixed to the adjacent tube without welding or other means of physically joining in a manner which prevents vertical or rotational movement. The paired collars are physically joined as by welding so that the fixed collar fixes the spacing between tubes and maintains them in the same horizontal plane while allowing for relative vertical movement. As illustrated the fixed collar is locked by being mounted on a curved tube section having a curvature sufficient to prevent relative vertical movement and through interference with the collar wall to prevent relative rotational motion.

  • Patent number: 5004456
    Abstract: A catheter intended for the administration of an anesthetic into a body space and methods of use such as introduction within the interpleural space are disclosed. According to the disclosure, the catheter is constructed so that only a soft distal portion resides within the body space. A relatively stiff portion joined to the relatively soft portion is intended to extend from the relatively soft portion through the dense body tissue to the proximal end of the catheter. A bio-compatible resin providing a softness of about 80A to 100A Rockwell is used for the relatively soft distal portion. A bio-compatible resin providing a catheter portion having a durometer value of about 65D to about 75D Rockwell is used for the relatively stiff portion. The relatively soft portion avoids damage to the delicate body tissue bounding the space whereas the relatively stiff portion resists kinking or collapse, both within the relatively stiff body tissue and outside the body.

  • Patent number: 4961977
    Abstract: Composite articles comprising a matrix material and reinforcing fibres coated individually or in tows with a support layer and methods of making the same are disclosed. The support layer is capable of supporting the fibres and preventing kinking thereof when the article is deformed while the matrix material is relatively soft. Polymeric matrix and support layer materials, either thermoplastic or thermosetting, are disclosed. When the support layer comprises a thermoplastic material, it should be selected to have a softening temperature which is higher than any temperature to which the article is heated for deformation. If matrix material and support layer are thermoplastic, the materials should be selected so that the softening point of the support layer is at least C. higher than that of the matrix, especially at least C. higher. According to the disclosure, the fibres are arranged so as to deform in a trellis deformation when the article is deformed.

  • Patent number: 4946722
    Abstract: Tubular sleeves formed from elongated flat sheets, particularly braided sheets are disclosed. Sheet material comprised of interlaced monofilaments is cold worked by the process of drawing the interlaced monofilaments over a forming edge with sufficient force and in a direction causing permanent elongation of the molecules of material on one side of the interlaced monofilaments. The cold worked monofilaments impart a permanent bias to the sheet causing it to curl about its longitudinal axis. Sleeves so formed may be slipped over or wrapped around bundles of wires or other elongated substrates, particularly those which include terminals, plugs and connectors of irregular dimension.
