  • Patent number: 7623333
    Abstract: The ion chip operating module allows for the inevitable ionizing electrode erosion by high voltage ionization of the prior art ion chip, by extending its life, improving its performance and maintenance. A ionizing module is provided which lengthens the life of its ionizing structure by providing more ionizing electrodes, which usually operate sequentially, and also allows replacement of an exhausted module by a fresh one. The ionizing electrodes are provided by ionizing needles, conductive carbon coated fibers and mixtures thereof. The carbon coated fibers when in brush form present a very large number of potential ionizing electrodes. The module is a metal plate with the ionizing structure on one side and a pin adapted to engage a socket on the other. The advantage of injecting negative ions into air conditioning systems to enhance air quality by increasing negative ions and by precipitating particulate contaminants is known.

  • Patent number: 6236001
    Abstract: A scoop has a handle attached thereto by a neck. The neck has a built in strain gauge supporting the scoop which measures weight in the scoop. An analog-digital converter converts the strain gauge output to a digital signal, which displays the weight as a readout (either metric or avoirdupois) on a panel in the handle. Control switches built into the handle or panel control the functions of the scoop, while indicator/annunciator lights indicate status. A level indicator is provided having a ball bearing resting freely on a conducting bottom plate forming a spherical sector of predetermined angle and a cylindrical sidewall having therein conducting elements. When the ball bearing contacts a sidewall conducting element it closes a circuit which switches off a level indicator/annunciator light, which when on shows that the scoop is level. The position of the ball bearing is visible to the operator, allowing correction of tilt.

  • Patent number: 5873447
    Abstract: A grain elevator auger uses a hydraulic cylinder incorporating a checkvalve. This checkvalve enables the volume of hydraulic fluid required to raise the elevator to be reduced to that required to replace the extended piston rod, instead of the full volume of the cylinder. The necessary capacity of the tractor hydraulic system reservoirs which are used to raise the elevators are similarly lessened. The checkvalve prevents hydraulic pressure retracting the piston, pressure is equalized on both sides of the cylinder piston, which then retracts slowly under the weight of the elevator, rather than rapidly under hydraulic pressure.

  • Patent number: 5685763
    Abstract: A method of stripping leaf cutter bee nest blocks passes several sets of stripping pins through the block in a single pass. Each set of pins has a different length, the lengths differ so that only one set of pins at a time contacts the seal plugs in the nest block tunnels. One set of pins contacts the plugs and breaks them loose before next set contacts the plugs. The pins are spaced so that each pin of a set is not directly adjacent a pin of an immediately preceding or succeeding set. The method increases speed and reduces cocoon crush.

  • Patent number: 5542496
    Abstract: A circular robotic device has retractable extendible surface engaging drives controlled by linear actuators. A pressure transducer indicates the pressure exerted by one such drive on the surface if the pressure is to high the drives are retracted, if the pressure is too low the drives are extended. A more sophisticated version controls the pressure exerted by each drive independently. In a pole centering version this providing a tight clamp allows the device to climb and descend the typically tapered poles. The device can prime and paint poles to predetermined thickness, as well as sandblast the poles. In a pipe cleaning version the drive engage the internal surface of a pipe. The pipe cleaning version carries pipe cleaning and/or X-ray equipment. A microprocessor monitors the device and provides status information to a remote control unit.

  • Patent number: 5447573
    Abstract: A process of detoxifying gas plant filters for environmentally acceptable disposal involves immersing the filters in aqueous cleansing fluid in a tank, containing a suitable cleaning agent. When saturated they are then agitated and passed through compressing rollers to extract as much cleansing fluid as possible. The extracted cleansing fluid returns to the tank it came from. The filters are then subject to similar repetitive steps of immersion, saturation, agitation, compression and fluid extraction in subsequent tanks. Five such stages are provided usually with diminishing proportion of cleaning agent in the aqueous cleansing fluid. The last two stages are often rinsing with water, although this is not always the case. The cleaned filters meet environmental standards for landfill disposal. The toxin accumulate as sludge in the tanks and are periodically removed for disposal in approved hazardous waste disposal sites.

  • Patent number: 5261766
    Abstract: Vertical bore holes are constructed for municipal sanitary landfills by drilling or otherwise excavating holes of large dimension to substantial depth, in virtually all known soil conditions however variable. They can be excavated well below the groundwater table, then lined with an impermeable or other permanent liner. This allows the landfill area to be much more efficiently used for the storage of various waste products. Solid organic waste other than cellulosics can be anaerobically fermented to methane and compost. A central core shaft is used as gas removal vent and conduit. After methane generation and removal the resulting compost is removed for use as soil nutrients. This system fully complies with the Environmental Protection Act and other regulations now in force in North America. Air, soil, groundwater, and surface water pollution and contamination are eliminated as all waste storage is contained within its own environment below natural grade.
