  • Patent number: 4581478
    Abstract: A way to evacuate all moisture and air and then pressurize with SF.sub.6 gas, a cable and conduit system used for electrical power distribution and transmission lines, by fabricating a termination at each end. A termination is made up of a first end plate with a hole slightly larger than the conduit and sealed around the hole to the conduit. For a single phase cable, one electrical terminal is sealed as it goes through the first end plate and is connected to the neutral conductor. A second electrical terminal is sealed as it goes through a second end plate and is connected to the conductor. An enlarged conduit is spaced between these two end plates and is sealed to, the two end plates. A tire valve is installed in one end plate. A hole to fit a pipe nipple is made at the top of the enlarged conduit of one termination. A vacuum pump is connected to a pipe nipple screwed into the hole and the termination evacuated. SF.sub.

  • Patent number: 4486669
    Abstract: This invention relates to a new system for generating electrical energy by wind power.The wind generator is suspended in the air like a kite by wind currents and is attached to the earth by a high strength cable to which are attached electric cables and a natural gas pipe.The numerous small wind generators are mounted in a box-like kite enclosure, which are raised to the desired elevation by rotary blade power with the assistance of a gas balloon.The wind generator kite is raised and lowered to the proper elevation for maximum electrical output.A complete system, including control methods, permits the production of electricity at a lower cost than conventional methods and provides means for generating large amounts of power with a high load factor.

  • Patent number: 4451877
    Abstract: A new, small, light weight, low cost, electric battery system stores the energy in an electric field at a very high DC voltage in a condenser that has a very high dielectric constant. Present condensers are not competitive for battery use because the voltage is not high enough, the dielectric constant is not high enough, and a system is not available for reducing the space and cost of the accessories such as transformers, rectifiers, and switches.The new battery system has the potential for storing electric energy at a first cost of $5.00 per KW, with a weight of 4.4 pounds per KW, and in a space of 38 KW per cubic foot.

  • Patent number: 4408657
    Abstract: A new method for transporting low temperature heat long distances consists of a system of high pressure air with a high specific heat in a low heat loss and low cost non-metallic heat pipe that is coilable for plowing into the earth. The hot air is used for space heating or for heating hot water heating systems or for process heat.The purpose of the invention is to reduce cost and save fossil fuel. High pressure air as opposed to hot water or steam for moving heat energy ecologically sound. Remote geothermal hot water wells can be economically moved several miles or hundreds of miles to communities for space heating. Remote waste heat sources at electrical generating plants and other fossil fuel burning heat system can be transported long distances for building use.

  • Patent number: 4343665
    Abstract: This invention relates to a new method for manufacturing a SF.sub.6 pressurized gas continuous spacer cable, and improvements which reduce costs and improve quality control of high voltage cables. The conductor is passed through taping machines for surrounding the conductor with a continuous insulating spacer and through taping machines for applying a conducting shielding material which partially covers the spacer. The insulated and shielded cable is continued on in the same production line into conduit which is laid out horizontal in long lengths or is extruded loose-fit over the cable. The cable is then subjected to vacuum while in the conduit. Terminations are applied. Seals are tested for leaks. The cable is filled with SF.sub.6 gas to a high pressure. The cable is tested at 1.5 times its operating voltage to ground for 30 minutes without failure.
