  • Patent number: 5083929
    Abstract: A bulkhead grounding connector for a multi-conductor shielded cable is fabricated from a base and an identical cover. A resilient plastic tube is positioned within the cable between its metal foil and wire braid layers and provides a spring-like surface to push the wire braid against rigid conductive fingers located on the inner surface of the base and cover. Scraping motion of the fingers against the wire braid during assembly ensures removal of resistive oxides from the braid. Sharp dimples positioned longitudinally on the inner surface of the base and cover provide additional ground connection around the circumference of the cable.

  • Patent number: 4780023
    Abstract: The invention concerns a watering hose for use in gardens, parks, green-houses and other such places to water flowers and other plants, the hose having a flat, stiff blade or strip of extruded synthetic plastics material which is bonded to tubing provided with spray apertures so as to serve as a means of fixing the hose to the ground or to one or more supports such as a wooden fence. When fixed to the ground, the blade is thin enough to permit it to be forced into the ground along the edge of a lawn facing a flower bed or any other convenient position in a park, garden or other place where the watering hose is required.
