摘要： A method for producing a protective coating on the surface of a carbonaceous substrate is described. A substantially uniform coating of a liquid or solid precursor material is provided on the surface of the substrate. The precursor material is one which has boron-oxygen bonds and is substantially non-reactive with the substrate at a first relatively low temperature and is capable of reacting with the substrate at a second temperature which is substantially higher than the first temperature. The substrate is then raised to the second temperature to react the coating with the substrate to form a porous region of substantially uniform depth in the substrate surface. This region contains interconnecting interstices and boron carbide. The interconnecting interstices are then at least partially filled with a glass forming material such as boron, boron oxide, boron carbide, silicon, silicon alloy, silicon dioxide, silicon nitride, silicon oxynitride, germania, and mixtures thereof. A refractory coating may then be deposited on the filled layer. Also described is a coated article produced in accordance with the described method.

摘要： In the preferred embodiment of the present invention, a pulse fog generator powered by a resonant intermittent combustion device having a carburetor and a combustion antechamber, includes a starting air supply system for directing a flow of starting air into the antechamber, comprising an inlet/outlet check valve mounted over the discharge opening of a bellows that is reciprocated by a connecting rod eccentrically mounted to an electric motor. A priming pump is mounted on the carburetor, and comprises a priming fuel chamber hydraulically communicating with the carburetor and a piston reciprocatable within the priming fuel chamber to draw fuel from a fuel tank into the priming fuel chamber and to discharge the fuel from the priming fuel chamber into the carburetor. An on-off control for the combustion device includes a shut-off plate, disposed over the air inlet of the carburetor, affixed to a slidably mounted plunger so that the shut-off plate can be moved between a position covering and a position displaced from the air inlet. The pulse fog generator has a pressure responsive formulation control apparatus inserted between a formulation tank and means for injecting formulation into the exhaust tube of the combustion device. The control apparatus includes a shut-off valve biased to a closed position restricting the flow of the formulation, and a diaphragm actuator including an engagement pin, extending from a pressure actuated diaphragm, adapted to engage the shut-off valve and hold the valve in an open position while the combustion device is operating.

摘要： In one embodiment of the present invention, a pulse fog generator powered by a resonant intermittent combustion device having a carburetor and a combustion antechamber, includes a starting air supply system for directing a flow of starting air into the antechamber, comprising an inlet/outlet ball check valve mounted over the discharge opening piston chamber within which a piston head is reciprocated by a connecting rod eccentrically mounted to an electric motor. A priming pump is mounted on the carburetor, and comprises a priming fuel chamber hydraulically communicating with the carburetor and a piston reciprocatable within the priming fuel chamber to draw fuel from a fuel tank into the priming fuel chamber and to discharge the fuel from the priming fuel chamber into the carburetor. In lieu of the reciprocatable piston, a resilient priming bulb and valve assembly can supply the priming fuel to the throat passage of the carburetor in another embodiment. An on-off control for the combustion device includes a shut-off plate, disposed over the air inlet of the carburetor, affixed to a slidably mounted plunger so that the shut-off plate can be moved between a position covering and a position displaced from the air inlet. The pulse fog generator has a pressure responsive formulation control apparatus inserted between a formulation tank and means for injecting formulation into the exhaust tube of the combustion device.
