  • Patent number: 8975994
    Abstract: An inductor includes an inductor body having a top surface and a first and second opposite end surfaces. There is a void through the inductor body between the first and second opposite end surfaces. A thermally stable resistive element positioned through the void and turned toward the top surface to forms surface mount terminals which can be used for Kelvin type sensing. Where the inductor body is formed of a ferrite, the inductor body includes a slot. The resistive element may be formed of a punched resistive strip and provide for a partial turn or multiple turns. The inductor may be formed of a distributed gap magnetic material formed around the resistive element. A method for manufacturing the inductor includes positioning an inductor body around a thermally stable resistive element such that terminals of the thermally stable resistive element extend from the inductor body.

  • Patent number: 8962071
    Abstract: Cold-in-place asphalt recycling is disclosed. A foamed asphalt may be produced by injecting water and optionally compressed air into a hot asphalt stream. A lubricating surfactant may be added to the hot asphalt stream to improve performance. The foamed asphalt may be mixed with reclaimed material to provide a uniformly coated paving material that can compacted to a desired density.

  • Publication number: 20140327512
    Abstract: A resistor includes a substantially cylindrical resistive element having a resistance of less than about 1 m?, a substantially cylindrical first termination electrically connected to the resistive element and a second termination electrically connected to the resistive element. The substantially cylindrical first termination is hollow to allow for accepting a connection such as from a battery cable. In addition there may be sense leads present on the resistor. A method of forming a substantially cylindrical resistor includes forming a hollow cylindrical resistor body by rolling a flat sheet comprising a resistive element and a first termination and a second termination joined on opposite ends of the resistive element.

  • Patent number: 8682759
    Abstract: A brokering system and method for providing an incentive to end users of petroleum fueled vehicles to make use of retrofit kits for existing IC engines which permit the use of hydrogen blended with fossil fuels without technically invading or modifying the engine or its intended purpose or application. End users of retrofitted vehicles are provided with discounted fuel costs at authorized refueling stations. The end user's savings include: a) a reduction in refueling charges since the vehicl's reliance on fossil fuel (which is displaced by hydrogen in the engine), and b) by the purchase of methanol which can be set at a lower cost per calorific equivalent than a barrel of oil while also earning emission offsets to be exchanged by the owner of the retrofitted engine for cash. These emission offsets can then be sold to end users/creators of carbon credits.

  • Publication number: 20130041053
    Abstract: Disclosed is a process for producing copolyesters with high levels of recycled content. Scrap or post-consumer poly(ethylene terephthalate) is depolymerized by methanolysis or glycolysis to produce a purified, recycled dimethyl terephthalate which can be repolymerized with 2 or more diols. The polyesters of this invention have physical properties and an appearance that is similar to polyesters prepared from virgin monomers. In addition to dimethyl terephthalate, the polyesters can be prepared from recycled ethylene glycol recovered from depolymerization of poly(ethylene terephthalate) and/or 1,4-cyclo-hexanedimethanol prepared by hydrogenation of recycled dimethyl terephthalate or recovered from depolymerized polyester mixtures.
