Patents by Inventor Gaylord W. Penney

Gaylord W. Penney has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4940471
    Abstract: An improved device is provided for cleaning particles from the plates of a two-stage electrostatic precipitator using a small stream of high velocity air which is moved over the face of the collecting cell. The cleaning device can operate without disturbing the normal operation of the precipitator. The improved cleaning device using a vacuum stream of air is particularly useful in a two-stage gas-cleaning electrostatic precipitator having a close-spaced collecting stage wherein the high voltage low voltage plates are spaced very close together, typically about 0.0625 inches apart.
    Type: Grant

  • Patent number: 4861356
    Abstract: An improved method for energizing the high voltage plates in a gas-cleaning device is provided using a corona discharge. Also, an improved device for cleaning the particles from the precipitator plates using high velocity air is provided such that the cleaning can occur without the normal operation of the precipitator. These improvements are particularly useful in two-stage gas-cleaning electrostatic precipitator having a close-spaced collecting stage wherein the electrically isolated high voltage and electrically connected low voltage plates are spaced very close together, typically about 0.0625 inches apart.

  • Patent number: 4351648
    Abstract: An electrostatic precipitator air cleaner having a novel ionizer cell made up of a plurality of positively charged wire-like ionizer electrodes, a plate-like negatively charged passive electrode positioned between and parallel to each adjacent pair of ionizer electrodes, and a box-like enclosure surrounding the ionizer cell such that the side walls of the enclosure adjacent the outermost ones of the ionizer electrodes form grounded electrically conducting surfaces, a relatively high electrostatic field being produced in the region between the ionizer electrodes and the passive electrodes and between the ionizer electrode and the grounded surfaces. In a preferred embodiment, the ionizer electrodes and passive electrodes are impressed with relatively high voltages of equal but opposite polarity such that the spacing between an ionizer electrode and an adjacent passive electrode is twice the spacing between an ionizer electrode and the adjacent grounded surface.

  • Patent number: 4259707
    Abstract: A system for charging dust and the like particles entrained in a gas stream and which are to be electrostatically precipitated. An emitter electrode is disposed in the gas stream for producing ions of one polarity which charge particles in the gas stream. These ions of one polarity and the charged particles are attracted to a surface on which at least a portion of the charged particles collect. The invention resides in the use of a second emitter electrode for producing ions of the opposite polarity which neutralize the ions of the first polarity which have been attracted to the surface and prevent the build-up of a voltage gradient across the particle layer on the surface.

  • Patent number: 3966435
    Abstract: An electrostatic dust filter is provided for collecting electrically-charged dust particles which are deposited on fabric filter elements in an electric field so that the particles deposit in porous layers. The dust particles are charged in a manner to provide a mixture of particles charged with opposite polarities, and adjacent filter members are maintained at opposite polarities. Unidirectional electric fields thus exist between adjacent filter elements and the dust particles deposit on one or the other filter element according to their polarity. A relatively simple structure is provided which requires no separate electrodes to maintain the electric field.
