  • Patent number: 7422035
    Abstract: A flat pipe with variable flow capacity comprises a main body shaped as a flat tube wherein opposing ridges are installed at the inner upper and lower positions of the main body, and thin-film spacers are installed between said pairs of ridges, forming multiple passages in the main body. Due to the flexibility of the thin-film spacers, the passages of the main body may stretch to a larger diameter to adjust to increased flow. If the flow is significantly enlarged, the main body will flex at the ridges causing the thin-film spacers to separate which in turn opens flow to the main body, essentially creating one main passage with a large diameter. When flow is stopped or decreased, the main body will restore elastically and resume shape as a flat pipe. According to the above, the present invention discloses a pipe which is easily stored and prevents twisting which could result in deformation, breakage and flow interference.

    Abstract: A duct (10) is made up of a plurality of layers (11, 12, 13) of pliant material. The layers (11, 12, 13) are attached by stitching (20, 22) to form pockets (23, 24) between adjacent layers. One of the layers (11) is wider than the others and extends over the lateral edges (17, 19) of those layers (12, 13), and when the stitching (22) is applied, a loop (21) is formed. The loop (21) receives a strength member (26) which may be engaged by a clamp (31) carried by a bracket (34) which may be attached to a utility pole (30) to carry the duct (10) overhead. In another embodiment, a duct (40) includes enclosed loops (41, 42, 43) forming pockets (50, 51, 52). Stitching (54) connects the loops (41, 42, 43) and forms another loop (55) to receive a strength member (56). In yet another embodiment, the layers (61, 62, 63 and 64) are of different lateral widths, and the longest layer (64) extends around one of the edges of the other layers (61, 62, 63) to form a loop (71) when stitching (65) is applied.

  • Patent number: 6448497
    Abstract: Devices and systems for housing cables and conduits. An exemplary cable tray is described having a number of interconnectable base members fashioned of pliable elastomer that are designed to be disposed upon a rooftop, floor or other support surface. The base members each contain a number of channels within which cables or conduits are disposed. Separate grooves are provide to retain ground wires. The base members may be formed to provide straight runs, angled turns or T-connection sections that are used as intersections. Cover pieces, also fashioned from pliable elastomer are removably affixed to the base members to enclose the cables or conduits. It is currently preferred to fashion the base member and cover components of the cable tray from crumb rubber or other recycled rubber. The components may thus be easily colored during manufacture. This same material is used for fabrication of interconnectable elements used to create walkways in accordance with the present invention.

  • Patent number: 6190349
    Abstract: A multiple lumen catheter assembly and methods for inserting the same are provided. The assembly includes a splittable membrane joining a first catheter and a second catheter for allowing the catheters to be at least partially longitudinally split from each other. Each catheter has at least one lumen extending longitudinally through the catheter. One method for inserting the assembly includes making an incision near the area to be catheterized, at least partially splitting the distal end regions of the catheters from each other by splitting apart the splittable membrane, and inserting the distal end regions of the catheters in a juxtaposed relation through the incision and into the area to be catheterized. In another method, the catheters are first tunnelled subcutaneously by pulling the distal end regions of the catheters in the assembly through a tunnel and outwardly from the tunnel near the area to be catheterized, leaving proximal end regions at least partially within the tunnel.
