In a gas insulated bus having a conductor supported in a cylindrical metal container via an insulator, insulating gas being contained in the metal container, the metal container has an expanded diameter part formed over a given range in an area of the metal container in which the insulator is positioned and a reduced diameter part formed over the entire area of the metal container except for the expanded diameter part. Thus, when the temperature of the insulator increases during conduction, heat from the insulator is transferred to the metal container via a large space in the expanded diameter part and released to the air through a large outer surface of the expanded diameter part of the metal container.

  • Patent number: 7411772
    Abstract: Techniques in which a 1st force, field, or effect caused by a Casimir effect is converted into a 2nd force, field, or effect. The 1st force, field, or effect might be distinct from the 2nd force, field, or effect only in the net vector or might be distinct in other ways. For example, the distinction might involve substituting a torque for a linear force vector or converting a force, field, or effect associated with the Casimir effect into movement or into an electric, magnetic, or electromagnetic force, field, or effect. These changes preferably are caused by an independent element placed proximate or between to the Casimir effect surfaces. Preferably, the torque causes rotation (i.e., spinning) of an element. This rotation is significantly different from prior-art embodiment because energy does not have to be put back into the system to “reset” the structures.

  • Patent number: 7379286
    Abstract: A system is disclosed for converting energy from the electromagnetic quantum vacuum available at any point in the universe to usable energy in the form of heat, electricity, mechanical energy or other forms of power. By suppressing electromagnetic quantum vacuum energy at appropriate frequencies a change may be effected in the electron energy levels which will result in the emission or release of energy. Mode suppression of electromagnetic quantum vacuum radiation is known to take place in Casimir cavities. A Casimir cavity refers to any region in which electromagnetic modes are suppressed or restricted. When atoms enter into suitable micro Casimir cavities a decrease in the orbital energies of electrons in atoms will thus occur. Such energy will be captured in the claimed devices. Upon emergence form such micro Casimir cavities the atoms will be re-energized by the ambient electromagnetic quantum vacuum.

  • Patent number: 7240861
    Abstract: A corona charge spray gun for dispensing powders for powder coatings. The spray gun includes a housing defining a chamber terminating in an outlet passageway. A high voltage electrode is mounted in the chamber spaced upstream of the outlet passageway and a ground electrode is mounted in the chamber spaced upstream from the high voltage electrode. The ground electrode is selected to have a surface area sufficiently larger than the surface area of the high voltage electrode in order to allow high voltages to be applied to the high voltage electrode without arch discharging occurring in the chamber. An inlet opens into the chamber for conducting a powder-gas mixture into the chamber and the electrodes receive cleaning gases for avoiding powder deposits on the electrodes.

  • Patent number: 7236344
    Abstract: The apparatus for generating ionic flow of media includes a DC voltage supply having a positive terminal and a negative terminal with a collector connected to the negative terminal of the direct current voltage supply. The collector has a substantially tubular configuration with a rear and front section with inwardly tapering frusto-conical section therebetween. An emitter pin is connected to the positive terminal of the direct current voltage supply with the majority of the tip being located within the frusto-conical section of the collector. Alternatively, the front section of the collector may be made of a dielectric material, such as plastic. As a result, fluid flow, such as air flow, is generated from the input port of the rear section of the collector, through the frusto-conical section of the collector and out the output port of the front section of the collector.

  • Patent number: 7220341
    Abstract: This invention is to a process and system for controlling solids distribution in a gas-solids reactor. Solids distribution is controlled by controlling electrical charges between solid particles flowing between conductive surfaces within a gas-solids reactor. The electrical charges are controlled by conventional means such as by grounding the opposing conductive surfaces, or by applying a voltage to one of the opposing conductive surfaces.

  • Patent number: 7160365
    Abstract: An ion generating apparatus is built by sandwiching a dielectric layer between an induction electrode and a discharge electrode. The induction electrode is formed of a metal substrate of, for example, aluminum. Even when the apparatus is made larger, it offers improved mechanical strength compared with a conventional structure employing a dielectric layer formed of a ceramic substrate, a brittle material. The dielectric layer is formed of a thin film having an insulation breakdown withstand voltage of 30 V/?m or more and having a thickness of 30 ?m or less. The discharge electrode is formed on the dielectric layer such that the area occupied by the electrode portion of individual line-shaped electrodes is smaller than the area occupied by the non-electrode portion thereof. This helps to make the discharge voltage lower and to reduce the amount of ozone generated by electric discharge.

  • Patent number: 6804105
    Abstract: A polymer material comprising channels whose temperature-independent conductivity exceeds 106 S/cm is used to form conductive films. Conduction takes place through threads and channels passing through the film which is otherwise a dielectric. The film is produced by first depositing a macromolecular polymer substance on a substrate. During preparation, the substance is preferably in a viscous liquid state. Stable free electrons (polarons) are then created by ionizing the substance. This is assisted by exposure to UV radiation and the presence of strong polar groups in the polymer. Various enrichment techniques, such as applying a strong electric field, are then used to join the superpolarons together into conductive threads within the medium. To stabilize the positions of the threads, the medium then may be solidified, preferably by cooling it below its glass transition point or inducing cross-linking between the macromolecules. The film may be a membrane.
