Abstract: A first solution of an electrolyte is injected underground into a volume of soil having negative surface charges on its particles. A cationic surfactant suspended in this solution neutralizes these surface charges of the soil particles within the volume. Following the first solution, a cationic asphalt emulsion suspended in a second solution is injected into the volume. The asphalt emulsion diffuses through the volume and electrostatically bonds with additional soil surrounding the volume such that an electrically conductive water repellant shell enclosing the volume is formed. This shell prevents the leaching of electrolyte from the volume into the additional soil. The second solution also contains a dissolved deliquescent salt which draws water into the volume prior to the formation of the shell. When electrically connected to an electrical installation such as a power line tower, the volume constitutes a grounding electrode for the tower.
Abstract: The invention is an improved method for the electrical grounding of insulation coated chain link fabric that is usually used for fences or similar enclosures. The invention provides a continuous wire at the top or bottom, or both, edges of the erected fabric that electrically connects each of the insulation coated wires which make up the fabric. The continuous wire is then grounded at intervals along the length of the fence or enclosure and thus effectively electrically grounds the fabric. Numerous variations in the configuration of the wire are included in the embodiments for accomplishing the grounding.
Abstract: The invention is an improved method for electrical grounding of plastics coated chain link fabric that is usually used for fences or similar enclosures. The invention provides a method for grounding by employing an insulating coating containing conductive particles to form a continuous linkage or electrical path through and between all wires that compose the fabric. The said fabric, after said continuous linkage or electrical path is established, is then grounded at various intervals along the length of the fence or enclosure and thus effectively electrically grounds the fabric.
Abstract: A method for installation of a grounding pole by boring in advance a hole with a desired depth into the earth, fitting a tip end of a grounding pole with a length almost equal to the depth of the hole to a guide tube and inserting the grounding pole with the guide tube faced down into the hole.
Abstract: An improved electrode for electrically heating a subterranean formation includes a plurality of electrically conductive rod-like members that extend outwardly from a central well bore to provide increased area for conducting electrical current from a source into said subterranean formation. The improved electrode apparatus is adapted to be lowered into a well bore which has been drilled into the subterranean formation and, thereafter, the plurality of rod-like members are driven outwardly from the central well bore. Guide means are provided to direct the rod-like members outwardly into the subterranean formation as a central member is forced downwardly.
Abstract: An imaging or transfer roller comprising mechanism to couple the roller to a ground potential close to the imaging or transfer zone, is provided. The roller includes insulator members concentric with the roller shaft and conductive sleeves on the ends of the roller.
Abstract: A low resistance backfill material for use in anode beds for cathodic protection of subsurface metallic structures. The backfill material consists of a mixture of carbonaceous materials, a lubricant, and a surfactant, which material may be mixed with water and pumped as a high density fluidized suspension into the anode bed.
Abstract: A method and means for grounding the conductive layer of a long power cable is provided wherein at least one metal wire is provided which is connected on one end to the metal sheath prior to the application of an insulation sheath. The outer portion of the metal wire is pulled through an opening made at a predetermined place at the insulation sheath whereupon the hole in the insulation is sealed immediately. Thereafter the metal wire is electrically interconnected to the armor sheath either during or after the application of the armoring sheath layers.

Abstract: An apparatus for the repair of ingot molds is disclosed. The ingot mold rests upon a layer of graphite powder whereby current can be passed through the ingot mold without the need for grinding thereof.
Abstract: A device for preventing the entanglement or wedging of paint, water or air hoses with the tires of a vehicle being worked on. Specifically, an elongated, longitudinally extendable hose guide adapted to be engaged with the body or frame of a motor vehicle and the ground so as to provide a guide for a hose thereby preventing said hose from engaging the tires of the vehicle and additionally to provide a path to ground for any static electrical charges that may build up on the surface of the vehicle to be painted thereby reducing any bubbles or swirls in metallic paint finishes, and further eliminating the attraction of dust by the electrical charges.
