The use of the heated salt brine and adjuncts such as waste beet juice or molasses will prevent the solution from being diluted by holding it place with the sucrose or fructose based molasses used to bind the brine to the surface requiring deicing. The use of calcium chloride and magnesium chloride as adjuncts will increase the heated salt brine's effectiveness at lower temperatures.

    Abstract: A system for stripping an optical fiber includes a source of air and means for generating very short bursts of air. A heater heats the bursts of air to a temperature sufficient to remove the outer coating from an optical fiber, while maintaining the air isolated from the heat source. A single burst of heated air removes the outer coating of an optical fiber, within less than about one second. A series of closely spaced bursts or a prolonged burst of heated air may be used to remove an expanded length of fiber coating. Stripping may include translation of the fiber or the heater or portions thereof. The stripper may be configured to strip several loaded fibers or a single fiber.

  • Patent number: 6499670
    Abstract: A directional control valve having three positions controls the direction of flow through an asphalt distributor. The directional control valve is interposed between a pump and a feed line assembly to a spray bar. The directional control valve has a first position in which flow is recirculated through the pump, a second position in which flow is delivered to the spray bar and a third position providing for handspray and transfer operations. A pressure relief valve is provided for controlling return flow of asphalt from the spray bar to the tank. The pressure relief valve is open in spray bar circulation mode and is closed during a spraying mode. According to the preferred embodiment the directional valve and pressure relief valve are contained within a modular control valve assembly. The directional control valve eliminates the need to reverse the flow in one of the individual feed lines and feed line assembly connecting the modular control valve assembly to the spray bar.

  • Patent number: 6481641
    Abstract: A fuel injector assembly incorporating a heat exchanger and a fuel injector and being disposable in a bore in a mounting substrate such as an internal combustion engine or a hydrocarbon fuel reformer. The exchanger includes an outer wall in direct contact with the bore and also surrounds and supports the dispensing portion of the fuel injector, forming an annular plenum space therebetween. The heat exchanger has an inlet port and an outlet port communicating with the plenum space. The exchanger outlet port is connected to an inlet port of the fuel injector, such that fuel entering the fuel injector is preheated by passing first through the heat exchanger. In some applications, it may be desirable to maintain the fuel at a high pressure to prevent premature vaporization of the fuel in the exchanger and resulting vapor lock of the fuel system.

  • Patent number: 6453992
    Abstract: The present invention relates to a temperature controllable gas distributor which includes a cover having a first passage between its upper cover and lower cover, a second passage embedded along an edge portion of the upper cover, a first heater installed in the second passage, a support portion welded around the cover, and a distributing plate fixed at a lower portion of the support portion. The distributing plate includes a plurality of nozzles, and a third passage which is a passage of fluid is formed in the interior of the distributing plate 201. Second and third heaters are installed in the third passage. In the gas distribution apparatus according to the present invention, since it is possible to control the temperature of the cover and the distributing plate, namely, the entire portions contacting with gas, an abnormal reaction and liquefaction of a source gas can be prevented.

  • Patent number: 6325302
    Abstract: A spray assembly for applying material to an object is provided. The assembly includes a plurality of spray nozzles each having spray openings for applying material to the object. Four nozzles are provided having two orientations each orientation with two spray widths. The assembly also includes a plurality of valves for controlling the flow of material through each of the spray openings. A manifold supports the plurality of spray nozzles and the valves and defines a feed bore and a spray bore extending between the feed bore and each of the nozzles. Water passages are integral with the manifold to regulate the temperature of the material flowing through the spray bores.
