  • Patent number: 6508861
    Abstract: An improvement in an electrostatic precipitator and method for removing particulate contaminants entrained in a gas stream passed through an electrode arrangement in which particulates are charged in a first electrostatic field and subjected to a second electrostatic field to be removed and collected for further disposition. The electrode arrangement includes a charging section having a charging electrode and a field electrode, and a collecting section having a repelling electrode and a collecting electrode. The field electrode and the collecting electrode are integrated, providing a relatively compact construction, and the charging electrode and the repelling electrode are electrically separated by high voltage diodes in a single power supply arrangement such that the charging section and the collecting section each are provided with a corresponding electrostatic field operated at an optimum voltage and current for respectively charging and collecting particulate contaminants entrained in the gas stream.

  • Patent number: 6365112
    Abstract: Certain contaminants are removed from a stream of contaminant-laden commercial and industrial exhaust gases conducted through an electrostatic precipitator by passing a reagent fluid through corona discharge active zones to activate the reagent fluid as the reagent fluid is injected into the stream such that the activated reagent fluid reacts with the contaminant to be removed. A combination discharge electrode and injector carries a plurality of electrode elements which establish the corona discharge active zones and include injector passages juxtaposed with the corona discharge active zones. The reagent fluid is injected into the stream by delivering the reagent fluid through the injector passages such that the reagent fluid passes through the corona discharge active zones and is activated as the reagent fluid is injected into the stream.

  • Patent number: 5597304
    Abstract: A device for alerting a dentist when the angular position of the drill and the angular position of the tooth being drilled do not correspond so that during drilling the angular position of the hole being drilled does not change. The device includes a drill transducer, a tooth transducer, a central control unit, and an alarm. The drill transducer is attachable to a dental drill and generates a drill angular position signal representing an angular position of the dental drill. The tooth transducer is removably attachable to a tooth and generates a tooth angular position signal representing an angular position of the tooth. The central control unit compares the drill angular position signal and the tooth angular position signal to each other to determine if the difference is within the value of a predetermined difference angular position.

  • Patent number: 4551879
    Abstract: An entrance dust arrester is provided which vacuums the area directly under a door as the door is opened and closed, thereby preventing the tracking of debris into a clean area. A housing with downward facing vacuum apertures may be attached to the outside of the door or may be built into the door itself. A system of air directing vanes distributes the vacuum evenly. The vacuum source itself may be integral to the housing or may be external and connected by a moveable coupling. The vacuum source is turned on and off by either or magnetic reed switch or a pressure operated switch.
