Patent number: 6747205Abstract: The invention relates to a device for assisting in the measurement of the earth resistance comprising a ground rod with a wire coiled up on a reel or the like, and electrical connecting means for connecting the wire to the ground rod. To provide such a device which is practical to handle, simple, small, and capable of being produced at low costs, it is provided for the reel or the like to be rotatably mounted on the ground rod. A further improvement results in that the ground rod comprises an offset portion in whose region the reel or the like is rotatably mounted. Preferably, the electrical connecting means between ground rod and wire comprise sliding rings on the rotation axis, the reel or the like. For an rapid exchangeability of the reel, the latter may be mounted on the ground rod by a snap connection.Type: GrantFiled: March 7, 2002Date of Patent: June 8, 2004Assignee: Lem Norma GmbHInventor: Jurgen Gobelhaider

Patent number: 6727430Abstract: Methods and apparatus to secure a ground strap assembly to an electrically conductive member are disclosed. In a disclosed example, a ground strap assembly includes a bendable ground strap, and a grounding clip having at least one flange located to substantially prevent rotation of the clip relative to the bendable strap. The example ground strap assembly also includes a fastener securing the grounding clip to the bendable strap. It is not necessary to remove the fastener from the bendable ground strap to secure the ground strap assembly to an electrically conductive member.Type: GrantFiled: February 12, 2003Date of Patent: April 27, 2004Assignee: Senior Industries, Inc.Inventor: George J. Franks, Jr.

Patent number: 6703556Abstract: The present invention provides a method and apparatus for mobile lightning protection. In one embodiment of the present invention, a lightning interception rod is positioned above a vehicle. In one embodiment, the rod connects to four down-conductors to conduct the current supplied by the lightning towards the ground. In one embodiment, the four down-conductors are positioned in a rectangular configuration. In one embodiment, down-conductors are covered by a insulating material. In one embodiment, the insulating material is a 3 mm thick layer of polymer. In one embodiment, one or more chains are attached to the vehicle and allowed to contact the ground. In one embodiment, two chains are attached to the vehicle. One chain is positioned at the front of the vehicle and another chain is positioned at the back of the vehicle.Type: GrantFiled: May 7, 2001Date of Patent: March 9, 2004Inventor: Mat Darveniza

Patent number: 6555742Abstract: An earth ground terminal provides an electroconductive substrate part and an electroconductive spring contact which protrudes integrally from one edge of the substrate part toward the side opposite to the substrate part. Through holes which have undergone a burring process are formed in the aforementioned substrate part. The earth ground terminal is used to prevent electromagnetic inductive interference, high-frequency inductive interference, etc. The earth ground terminal is effective when a printed substrate is grounded by a shield plate or a chassis.Type: GrantFiled: December 23, 1999Date of Patent: April 29, 2003Assignee: Tyco Electronics Logistics AGInventor: Izuru Kumagai
