  • Publication number: 20100004863
    Abstract: A system determines dew point and temperatures through a mobile platform. The system identifies a likelihood of condensation forming on a roadway surface. A controller may process the data to determine the likelihood of frost, ice, and/or black ice conditions. Some systems provide aural, visual, and/or tactile signals or feedback to identify a condition or a change in conditions. The change, condition, and/or data may be associated with position data.

  • Publication number: 20090053664
    Abstract: A patio heater is disclosed comprising a cylindrical catalytic heating chamber mounted on a base. The patio heater of the present invention comprises a base to physically support a cylindrical catalytic heater chamber which is mounted inside a fuel vapor cavity. The catalytic heater chamber provides a cylindrical heating zone capable of heating a nearby human form the knee to the face. The fuel vapor chamber surrounds the catalytic heating chamber and acts to accumulate sufficient fuel and air mixture to ignite to provide uniform and sufficient heat to the catalyst surface to attain catalytic ignition on start up. The base offers physical stability for the assembly and storage space for a fuel tank and houses the fuel deliver system and ignitor controls.

  • Publication number: 20070221555
    Abstract: A system for dewatering a stream of slurry has a first and a second separator. The first separator removes objects above a first size, to produce a stream of primary treated slurry. The second separator removes objects above a second size from the primary treated stream, the second size being smaller than the first size. Optionally, a third separator removes objects above a yet smaller third size from the stream of secondary treated slurry. The first separator has a plurality of sieve mat supports alternately connected to a main support frame section and a movable support frame section so that the flexible sieve mat can be agitated by the movable support frame section, a collector being provided for collecting the primary treated slurry passing through the flexible sieve mat. In an optional step, water contained in the separated solids is removed.

  • Publication number: 20050070431
    Abstract: A coated article (e.g., 244) and a method for preparing a coating (e.g., 400) for a metallic substrate (402) are described. In one embodiment, the method includes preparing a ceramic powder comprising particles of a ceramic material (404) doped with a catalyst species (406). The method also includes adding metal particles (408) and the ceramic powder to a fluid to form a fluid suspension effective to maintain the catalyst species dispersed therein, and then applying the fluid suspension to the metallic substrate to form the coating thereon. In another embodiment, an aqueous suspension of undoped ceramic particles (316) may be combined with a fluid suspension of metallic particles to form the coating.

  • Publication number: 20010042721
    Abstract: A system and method for dewatering a continuous stream of slurry at high flow rates demonstrates enhanced efficiency, economy and ease of operation. A stream of slurry is subject to continuous or continual measurement of flow rate and pulp density and the measurements are used to control the rate of addition of a flocculating agent to the slurry. The flocculated slurry is delivered to a dewatering unit where it is passed through a diffuser and evenly delivered to a tracking screen for filtering solids from a liquid filtrate. The pulp density of the filtrate may also be measured and used to control addition of a flocculating agent. The tracking screen is adjusted to achieve an angle of repose suited to the particular composition of the filter cake. The diffuser has a base having a horizontal section aspect ratio of from about 1:1 to about 4:1 and continuously changing vertically into an upper portion having a horizontal section with an aspect ratio of from about 40:1 to about 100:1.
