  • Patent number: 5288552
    Abstract: This invention provides for a continuous PTFE fiber having on its surface a substantially round profile and a single spiralling seam formed from a continuous sheet of polytetrafluoroethylene which is helically rolled and self-adhered. The PTFE sheet may include microporous PTFE as well as expanded microporous PTFE. The PTFE sheet may be filled with particulate fillers or coated with polymeric coatings prior to the formation of the inventive fiber. The PTFE sheet may be used to contain various filamentary or sheet-like elements with the inventive fiber.The method for producing the inventive fiber is also disclosed.

  • Patent number: 5288266
    Abstract: A storage vessel for storing grain or other natural products comprises a gas-impermeable enclosure having a water-vapour-permeable membrane to allow the grain to breath and dry, and to prevent condensation and mould growth. The membrane is impermeable to oxygen gas to allow a reduced oxygen atmosphere (e.g. 3 to 7%) to be established as oxygen is used up by insect pests within the grain. The insects are unable to survive at such low levels of oxygen. Thus the grain is protected against pests without the use of chemical pesticides.

  • Patent number: 5262589
    Abstract: An electrical ribbon cable of parallel, coplanar conductive wires having an insulating layer of sintered porous PTFE tape around each of the wires, and a second insulating layer of porous sintered PTFE film around the wires. A conductive layer is then applied and then an outer insulating layer. The cable may be simply and quickly mass-terminated by means of standard tools and connectors. It is constructed such that the velocity of propagation of a signal along any wire is greater than 85% of the velocity of propagation of signals along similar wires suspended in air, and such that the time delay of signal propagation from one end of any wire to the other end is less than 1.17 nanoseconds per foot of length of the cable.
