  • Patent number: 8784028
    Abstract: A penetrating fastener has a fastener head and fastener tip spaced apart by a longitudinally oriented fastener shaft. A tetherable washer has a substantially planar base surface having a fastener aperture extending therethrough. A longitudinally oriented wall extends longitudinally upward from at least a portion of the base surface to form a concave fastener cavity configured to receive at least a portion of the fastener head. Two tether apertures extend laterally through the wall and are laterally spaced apart along the wall. Both of the tether apertures are laterally arranged along the wall in a rotationally asymmetric configuration. A first one of the tether apertures is located a second longitudinal distance from the base surface and a second one of the tether apertures is located a third longitudinal distance from the base surface. The tether apertures are configured to simultaneously accept a tether extending through both of the tether apertures.

  • Patent number: 7803488
    Abstract: An electrical power plant that includes a fuel cell and at least one recycle system for recycling at least a first reactant, for reuse by the fuel cell. The fuel cell discharges a first exit stream that includes the first reactant and inerts. The recycle system comprises a separator that receives the first exit stream from the fuel cell and separates the first reactant contained in the first exit stream from inerts contained in the exit stream. The separated first reactant is directed back to the fuel cell for reuse. The remaining inerts and unseparated first reactant are discharged by the separator and then recirculated back into the separator, without progressing through the fuel cell, to separate additional first reactant from the inerts.

  • Patent number: 6850008
    Abstract: A gas discharge lamp having a translucent envelope enclosing a light emitting assembly that includes a baffle and an anode separated by one or more spacers made of an electrically insulating material such as ceramic, which are oriented towards a heated cathode to receive electrons emitted therefrom. Each spacer has a front surface, a rear surface, a top surface and a bottom surface including a transverse cavity formed between the front and rear surfaces to permit electrons to flow through. The cavity extends from a first through-hole in the front surface to a second through-hole in the rear surface of the spacer. Further, the cavity includes a gap for allowing conductive materials that may sputter or evaporate from the anode or the baffle to escape from the cavity to prevent short circuiting between the anode and the baffle.

  • Patent number: 6613155
    Abstract: A method for servicing firefighter's turnout gear includes the step of transporting a mobile servicing facility in proximity to a fire department facility. The mobile servicing facility carries cleaning equipment for cleaning firefighter's turnout gear. For example, the cleaning equipment may include a cleaning machine for use with a carbon dioxide-based cleaning agent, a solvent, or laundry equipment. The method also includes the steps of operating the cleaning equipment to clean turnout gear of the fire department facility, and transporting the mobile servicing facility away from the fire department facility. Optionally, the mobile servicing facility also carries repairing equipment, supplies for repairing the turnout gear, power generation equipment, and/or a tracking system for preparing a report of services performed on the turnout gear.

  • Patent number: 6428134
    Abstract: Printer and method adapted to reduce variability in ejected ink drop volume. A print head includes a plurality of nozzles integrally attached to the print head, each nozzle being capable of ejecting an ink droplet therefrom. At least one of the nozzles has an undesirable characteristic producing ink droplets of non-nominal volume. A waveform generator is connected to the nozzles for generating a plurality of waveforms to be supplied to the nozzles, so that the nozzles eject the ink droplets in response to the waveforms supplied thereto. Each waveforms has a plurality of pulses controlling ink droplet volume. A controller is provided for controlling the waveforms supplied to the nozzles and for transmitting the waveforms to the nozzles in order to eject the ink droplets so as to compensate for the non-nominal volume by controlling the number of pulses in the waveform. In this manner, all nozzles produce ink droplets of nominal volume regardless of physical or electrical variations between nozzles.
