摘要： A vacuum cleaning tool adapter for vacuum cleaning systems having a control device incorporated within the adapter. The control device includes an electrical switch and may also include other circuit control devices. Also incorporated in the adapter is a connect-disconnect connector for mechanically interengaging the adapter with a hose assembly leading to the vacuum cleaner, which also provides electrical continuity from the adapter through current conducting reinforcing members in the hose assembly and into the vacuum cleaner. The adapter provides for electrically connecting the cleaning tool into the system, and the switch is used to turn the power on and off from the vacuum cleaner motor to the cleaning tool. An additional switch may also be located in the adapter for controlling the vacuum cleaner motor itself.

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.
