Coolant Is Spray Fluid Or Is Added To Spray Fluid Patents (Class 239/132.5)
  • Patent number: 6698667
    Abstract: A nozzle beam for descaling or cooling metal strand material, particularly rolling stock, includes an inlet for the product treatment liquid and an additional inlet for a device cooling liquid, an outlet for the device cooling liquid, and a switching member for opening and closing the device cooling liquid outlet. The switching member is automatically switchable through a device cooling liquid pressure which controls the state of operation of the nozzle beam.

  • Patent number: 6524096
    Abstract: A high-temperature burner is provided that is suited for the incineration of shredded plastics, tires, carpet or similar materials. The burner walls are protected from the heat of the ongoing combustion reaction by an annular curtain of water vapor or carbon dioxide that takes the radiant heat energy of the high-temperature combustion reaction. The annular curtain removes the heat energy from the vicinity of the burner walls before the energy can be conveyed to them. Higher temperature combustion can be attained without resorting to jacketed burner construction or the use of refractory materials.

  • Patent number: 6425532
    Abstract: A high pressure gaseous fuel injector for injecting natural gas or other gaseous fuels at high pressures (eg. 300 to 700 psig more or less) into combustion engines for improved efficiency, better performance and reduced environmental emissions. The fuel injector includes an outer cartridge housing and a universal valve cartridge mounted therein. Spring washers are used to urge the valve cartridge against a metal O-ring supported by the outer cartridge housing.

  • Patent number: 6360963
    Abstract: A high pressure gaseous fuel injector for injecting natural gas or other gaseous fuels at high pressures (eg. 300 to 700 psig more or less) into combustion engines for improved efficiency, better performance and reduced environmental emissions. The fuel injector is powered by hydraulic signals from an electrohydraulic valve. The fuel injector includes an outer cartridge housing and a universal valve cartridge mounted therein. The cartridge comprises an activator body and a valve body secured together, and the valve body has a gas valve slidable therein. The stroke of the valve is adjustable by controlling the size of shims in the valve body assembly, thereby providing a universal valve cartridge that can be easily adapted to differing fueling requirements for models and sizes of engines. The valve body includes a spring chamber between upper and lower valve guides.

  • Patent number: 6283091
    Abstract: An engine exhaust braking method and apparatus. The method includes injecting a predetermined amount of fuel per stroke into an engine cylinder during engine braking, wherein the predetermined amount of fuel cools the fuel injector nozzle, thereby allowing the engine braking to be performed without damage to the fuel injector nozzle due to excessive heat. The apparatus includes a fuel injector having a nozzle and capable of injecting a predetermined amount of fuel into an engine, and a processor connected to the fuel injector, with the processor monitoring engine operation and capable of causing the fuel injector to inject the predetermined amount of fuel into the engine, wherein a predetermined amount of fuel is injected into the engine to cool the fuel injector nozzle, thereby allowing the exhaust braking to be performed without damaging the fuel injector nozzle due to excessive heat.

  • Patent number: 6205799
    Abstract: A spray cooling system for semiconductor devices. An ink-jet type spray device sprays droplets of a cooling fluid onto the semiconductor devices. The devices vaporize the liquid, which gets passed through a roil bond panel, or other heat exchanger, and is pumped into a spring loaded reservoir that feeds the spray device.
