  • Patent number: 10281423
    Abstract: The fuel quality sensor includes two rectangular parallepiped waveguides of equal dimensions stacked one atop the other and having a common ground. A thin wire extends through the intermediate wall(s) between the upper and lower waveguide cavities. An input connector is mounted on a sidewall of the upper waveguide, and an output connector is mounted on a sidewall of the lower waveguide cavity. A fluid conduit extends through the upper waveguide cavity adjacent the wire. A tunable microwave signal or wideband time domain pulse is applied to the input connector while fuel is flowing through the conduit. If the fuel flowing in the conduit is uncontaminated, the output signal at the second connector will show no change from the tunneling frequency, but if the fuel is contaminated, the change in the fuel's dielectric constant will result in a change in tunneling frequency and/or tan ? at the second connector.

  • Patent number: 9950977
    Abstract: Polyhydroxyfullerenes (PHFs) having enhanced electron scavenging capabilities have a ratio of non-hydroxyl functional groups to hydroxyl functional groups that is less than or equal to 0.3. When combined with a semiconductor photocatalyst, such as titanium dioxide nanoparticles, the PHFs provide a photocatalyst for degradation of chemical and biological contaminates with an efficiency of at least twice that of titanium dioxide nanoparticles free of PHFs. The PHFs are included in these catalysts at a weight ratio to titanium dioxide of about 0.001 to about 0.003, whereas significantly lower and higher ratios do not achieve the highly improved photodegradation capability. PHFs outside of the desired structure are shown to be of little value for photodegradation, and can be inhibiting to the photocatalytic activity of TiO2. The enhanced electron scavenging PHFs can be employed as a component of materials for solar cells, field effect transistors, and radical scavengers.

This control permits the emulation of the behavior of wireless communication terminals under different fading scenarios, both indoors and outdoors. Some of the features and procedures of the MIMO analyser may be used in industrial microwave heating processes for drying and curing of materials, also known as microwave ovens, allowing a greater efficiency and homogenization in the processes.

  • Patent number: 8604398
    Abstract: A method of purifying a target powder having an oxygen content, the method comprising: flowing hydrogen gas through a microwave production chamber; applying microwaves to the hydrogen gas as the hydrogen gas flows through the microwave production chamber, thereby forming hydrogen radicals from the hydrogen gas; flowing the hydrogen radicals out of the microwave production chamber to the target powder disposed outside of the microwave production chamber; and applying the hydrogen radicals to the target powder, thereby removing a portion of the oxygen content from the powder. Preferably, the target powder is agitated as the hydrogen radicals are being applied.

  • Patent number: 8586898
    Abstract: The invention described herein pertains generally to a more efficient and cost-effective method and apparatus for: (1) coupling of microwave energy from a microwave generator or plurality of microwave generators into an integral set of applicators; (2) extraction and separation of organic compounds from a mixture of organic and inorganic compounds; and (3) recovery and conversion of the organic compounds to gaseous and liquid fuels. The apparatus described in this invention result in improved microwave absorption within the mixture flowing through the applicators by increasing residence time within the applicators, resulting in a higher temperature within the material. The higher temperature lowers the viscosity of the solution, but also provides a limited reduction of the combination of complex chain and aromatic organic compounds to allow recovery of syngas and fuel oil.

  • Publication number: 20130228446
    Abstract: A device and process for removing contaminates from a process fluid employing microwave energy has been described. The use of a quartz tube, which allows for the efficient transfer of microwave energy to a contaminated process fluid is employed to raise the temperature of the process fluid and a flash vaporization technique allows for the removal of uncontaminated fluid. This process decreases the amount of scaling that may collect on the surfaces of the device which increases the devices efficiency and useful life.

  • Patent number: 8492690
    Abstract: A microwave susceptor system for cooking food in a microwave. The microwave susceptor system generally includes a platform having a support layer and a susceptor layer, sidewalls foldably connected to a first and second side of the platform and adapted to extend upwardly therefrom, and end walls foldably connected to a third and fourth side of the platform and adapted to extend upwardly therefrom. Each of the sidewalls and end walls have a support layer and a susceptor layer. Extending from each sidewall opposite the platform is a support leg. The support leg is foldably connected to the sidewall and extends downwardly from the sidewall below the platform to elevate the platform above the microwave cooking surface. The support legs are retained in position by outwardly extending flaps that connect to an adjacent end wall via a slot within the end wall.

  • Patent number: 8492686
    Abstract: A method of heating and/or thawing using an RF heater is described. In some cases the heating differentially heats portions according to their dissipation ratios. Optionally, this avoids dissipating large amounts of energy into thawed portions while frozen portions are still extant and heat slowly. Optionally, this prevents overheating of thawed portions.

  • Patent number: 8450667
    Abstract: A flexible, electrically heatable hose having an elongated electrical conductor which extends in the helical shape in the hose direction is illustrated and described. The object of providing a flexible, electrically heatable hose in which uniform heating over the hose length is ensured even in the event of major deformation of the hose, is achieved by a hose which has an elongated electrical conductor which extends in a helical shape in the hose direction, wherein the electrical conductor is embedded in a braid. In this case, the braid has first and second strands, wherein the first strands extend in a helical shape in the hose direction in the same winding direction as the electrical conductor, and the second strands extend in a helical shape in the hose direction in the opposite winding direction to the electrical conductor. The pitch angle of the electrical conductor, which extends in a helical shape in the hose direction, of the first strands and of the second strands is in this case between 50° and 80°.

  • Patent number: 8440946
    Abstract: Coal is processed to produce relatively pure carbon particles of small size by first subjecting mined coal fragments to microwave energy to vaporize the water, mercury, sulfur, and like contaminants and to increase the friability of the coal. Next the fragments are pulverized and then reduced in a jet mill to produce particles of small maximum size and fine particles having an average size of about 20 microns, for use in a power plant or as a fuel for a turbine or diesel engine.
