  • Patent number: 9000334
    Abstract: A Bleve (Boiling Liquid Expanding Vapor Explosion) reaction wherein fuel is pumped from a fuel line and is fed through a solenoid valve to a BLEVE reaction chamber. The BLEVE reaction takes place in the bleve chamber, during which a bleve is released and supplied via the bleve outlet nozzle. A thermal housing with embedded electrical resistive wire, is a method and installation for generating sufficient heat causing a bleve. The fuel is heated by the electrical resistive wire as it is moved into the bleve-reaction chamber. As bleved fuel is introduced into the combustion chamber, the latent heat causes the bleve to auto-ignite upon contact with the oxygen producing a blue flame. The cycle of the process is controlled by means of a regulating control. The method described is particularly suited for a bleved fuel valve nozzled burner.

  • Patent number: 8415594
    Abstract: The invention relates to a method for operating an induction heating device. The induction heating device comprises an induction coil and a frequency converter for producing a control voltage for the induction coil. The frequency converter comprises a rectifier rectifying an alternating supply voltage (UN), an intermediate circuit capacitor, looped in between output terminals of the rectifier and equalizing the rectified voltage (UG), and at least one controllable switching element, looped in between the output terminals of the rectifier. According to the invention, in a predetermined discharge interval (INT) before a zero crossing (ND) of the alternating supply voltage (UN), the intermediate circuit capacitor is discharged to a threshold value by controlling the at least one switching element before the induction coil is controlled in order to produce an adjustable heating capacity.

  • Publication number: 20130062340
    Abstract: A centrifugal magnetic heating device includes a power receiving mechanism and a heat generator. The power receiving mechanism further includes a vane set and a transmission module. The heat generator connected with the transmission module further includes a centrifugal mechanism connected to the transmission module, a plurality of bases furnished on the centrifugal mechanism, a plurality of magnets furnished on the bases individually, and at least one conductive member corresponding in positions to the magnets. The vane set is driven by nature flows so as to drives the bases synchronically with the magnets through the transmission module, such that the magnets can rotate relative to the conductive member and thereby cause the conductive member to generate heat.

  • Publication number: 20130062339
    Abstract: A tool to supply heat to a PEX pipe to permit the PEX pipe to be removed from a fitting connection includes a thermal element that can supply heat to the PEX pipe. The thermal element may be heated via electrical processes, such as resistive or inductive heating, or may be heated with a combustion process. The thermal element may be implemented in a pliers to permit the heating element to be placed around the PEX pipe and clamped, to allow the user to pull the PEX pipe off the fitting connection using the pliers. The tool may have a temperature control to regulate an amount of heat provided to the PEX pipe during removal, which control may include a feedback transducer, such as a thermocouple. The tool may be operated with AC or DC power, where the DC power may be provided by one or more batteries.

  • Patent number: 8389910
    Abstract: A wiper assembly having a wiper with an inductively heatable portion, and an induction heating device including an induction work coil which is configured to be placed near the wiper to inductively heat the inductively heatable portion. The inductively heatable portion may be in the wiper blade, the wiper arm which supports the blade, or both. The induction work coil may be placed on or near the windshield or other surface which is cleaned by the wiper and may heat the wiper regardless of its position or only when the wiper is at a specific location such as its retracted “rest” position. The wiper assembly may also include a temperature sensor for sensing a current temperature of the wiper and control circuitry associated with the induction heating device for controlling operation of the work coil.

  • Patent number: 8373103
    Abstract: An apparatus for heating and impelling air comprises a housing, an air heating impeller assembly, and a magnetic assembly. The impeller assembly may impel air through the housing and heat the air, and may include a support shaft, a plurality of annular disks positioned along the support shaft and each having a central aperture through which the support shaft extends. The impeller assembly includes paddles radiating outwardly from the shaft, and each of the paddles is positioned between the shaft and the disks to space at least one disk from the support shaft to form an air path therebetween. The paddles space the disks in an axial direction to form gaps therebetween to form an air path between the disks. The magnetic assembly applies a magnetic field of adjustable intensity to the disks to cause heating of the disks.

    Abstract: The present disclosure relates to brazed coated diamond-containing materials and methods of producing brazed coated diamond-containing materials. The method for brazing the coated diamond-containing material may include bringing a braze metal into contact with the refractory metal layer and a substrate; heating at least the braze metal above the melting temperature of the braze metal; and bringing the braze metal into contact with the substrate to form a braze metal layer to join the diamond-containing material, braze metal layer, and substrate together. An advantage of the method may include that the brazing step may be performed in air, under ambient pressure, and without the need for a protective layer.
