  • Patent number: 7459138
    Abstract: A process and apparatus for catalytic production of single walled carbon nanotubes. Catalytic particles are exposed to different process conditions at successive stages wherein the catalytic particles do not come in contact with reactive (catalytic) gases until preferred process conditions have been attained, thereby controlling the quantity and form of carbon nanotubes produced. The reaction gas is preferably provided at a high space velocity to minimize CO2 build-up. The process also contemplates processes and apparatus which recycle and reuse the gases and catalytic particulate materials, thereby maximizing cost efficiency, reducing wastes, reducing the need for additional raw materials, and producing the carbon nanotubes, especially SWNTs, in greater quantities and for lower costs.

  • Patent number: 7451568
    Abstract: A subsurface pest detection and pesticide injection system in combination with a structure having a foundation including a tubular conduit disposed adjacent the foundation of the structure. The tubular conduit has a plurality of pores extending through the sidewall of the tubular conduit. The tubular conduit is constructed of an elastomeric material such that upon applying a negative internal pressure to the tubular conduit the pores of the tubular conduit are caused to open to permit the drawing of gas into the tubular conduit, and upon removal of the negative internal pressure the pores are caused to close so that the pores remain substantially clog free. A means for applying a negative internal pressure is in gas communication with the tubular conduit to cause the pores of the tubular conduit to open and cause gas to be drawn into the tubular conduit.

  • Patent number: 7446292
    Abstract: An auto darkening eye protection device comprising a shutter assembly and a control circuit. The shutter assembly is adjustable between a light state and a dark state. The control circuit comprises a sensing circuit, a weld detect circuit, a positive voltage generator, and a negative voltage generator. The sensing circuit senses incident light and provides an output indicative of the incident light. The weld detect circuit receives the output of the sensing circuit, and enables a dark state drive signal to be delivered to the shutter assembly. The positive and negative voltage generators output the dark state drive signal to the shutter assembly to switch the shutter assembly from the light state to the dark state upon enablement by the weld detect circuit. The dark state drive signal includes a high voltage pulse followed by a stable AC waveform. The high voltage pulse is formed by a positive voltage signal and a negative voltage signal.

  • Patent number: 7435944
    Abstract: An optically-powered integrated microstructure pressure sensing system for sensing pressure within a cavity. The pressure sensing system comprises a pressure sensor having an optical resonant structure subject to the pressure within the cavity and having physical properties changing due to changing pressures within the cavity. A substrate supports the optical resonant structure. An input optical pathway evanescently couples light into the optical resonant structure. An output optical pathway collects light from the optical resonance structure. A light source delivers a known light input into the input optical pathway whereby the known light input is evanescently coupled into the optical resonant structure by the input optical pathway and a portion of such light is collected from the optical resonant structure by the output optical pathway.
