  • Patent number: 5203542
    Abstract: An improved electric fence wire construction, especially for intensive grazing, is comprised of an electrically conductive wire core, sandwiched between the two halves of a single strip of thin metallic foil. The foil is folded upon itself, enveloping the wire core. The halves are bonded together by a suitable adhesive which does not inhibit flexibility of the improved wire. The foil serves to purposes, the first being to enhance visibility for the animals. Secondly, the foil offers much more electrically conductive surface area than a bare wire, so a more effective deterrent is presented to the animal. The wire can be used as a component of a permanent electrified perimeter fence, or in a temporary movable electric fence. The improved wire is especially useful in a method of intensive grazing wherein the improved wire is a component of at least two temporary fences that are moved at regular intervals.

    Abstract: An elemental net for a multiple element aircraft arresting net system. The elemental net has a single upper horizontal strap, several vertical straps having top ends and bottom ends, and at least two lower horizontal straps. The top ends of the vertical straps are directly affixed to the upper horizontal strap at spaced intervals along the upper horizontal strap. The bottom ends of the vertical straps are alternatingly affixed to one of the lower horizontal straps so that the lower horizontal straps are free to move relative to each other to a significant degree and so that lifting of one vertical strap will tend to lift only one of the lower horizontal straps in the vicinity of the vertical strap being lifted. The present invention provides a variable window which is free to expand or contract during aircraft engagement, permitting easier penetration of the net by a greater mix of aircraft.

  • Patent number: 4730810
    Abstract: The protective barrier comprises a sheet of netting substantially following the ground transverse to the slope and held spread out upright by posts. The posts are held by upstream and downstream stays on a guide in the direction of the slope, the guide being formed by a loop of cable stretched between two pulleys anchored in the ground and having a bearing strand to which the stays and the post are attached. A mooring cable upstream of the netting retains the attachment place of the upstream stay on the bearing strand. The cable is equipped with shock-absorbing means adapted to allow a length of reserve cable to run when subjected to strong tension. The impact of blocks of stones causes the posts to fall back on either side of the place of impact, the motion being slowed down by the shock-absorbing means. The sheet of netting remains stretched and the posts do not bend.

  • Patent number: RE32934
    Abstract: A flexible barrier element for a passageway defined by two spaced posts is held in a raised taut position to block the passageway by placement of a hand lever having a lost motion connection with the barrier element in a level position of engagement with a bracket fixed on one post. Swinging of the hand lever to a depressed position relative to the bracket on which it is pivotally mounted slackens the flexible barrier element and lowers it to a ground level position allowing unobstructed passage between the posts defining the passageway. A second bracket on the second post has a flexible barrier element attached to it.
