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.

Abstract: An electrostatic fluid accelerator having a multiplicity of closely spaced corona electrodes. The close spacing of such corona electrodes is obtainable because such corona electrodes are isolated from one another with exciting electrodes. Either the exciting electrode must be placed asymmetrically between adjacent corona electrodes or an accelerating electrode must be employed. The accelerating electrode can be either an attracting or a repelling electrode. Preferably, the voltage between the corona electrodes and the exciting electrodes is maintained between the corona onset voltage and the breakdown voltage with a flexible top high-voltage power supply. Optionally, however, the voltage between the corona electrodes and the exciting electrodes can be varied, even outside the range between the corona onset voltage and the breakdown voltage, in to vary the flow of fluid.

Abstract: Apparatus and method for removing particulates and corrosive gases from a gas stream includes the serial use of a condensing wet electrostatic precipitator section for removing smaller particulates, in the submicron range, in conjunction with a vertically aligned preliminary scrubber section which removes larger particulates, in the micron range, and corrosive gases, in an integrated unit in which the temperature and moisture conditions in the gas stream are controlled for assuring effective and efficient operation of the condensing wet electrostatic precipitator section. Discharge electrodes of the electrostatic precipitator are supported by insulators which are protected against deleterious deposits of particulates by discharge electrode elements and collector electrode elements placed between the gas stream and the insulators.

Abstract: An improvement in the operation of a thermal oxidizer during regeneration of an adsorber, wherein adsorbates collected in the adsorber are removed from the adsorber and introduced into the thermal oxidizer, by regenerative steam passed through the adsorber, to be oxidized in the thermal oxidizer during a regenerative cycle of prescribed duration, regulates the concentration of adsorbates in the regenerative steam passed to the thermal oxidizer such that the concentration of adsorbates introduced into the thermal oxidizer throughout the duration of the regenerative cycle is regulated to avoid excessive deviations from a selected average concentration of adsorbates, the regulated concentration of adsorbates enabling more efficient operation of the thermal oxidizer throughout the full duration of the regenerative cycle.

Abstract: A selective vertical locking mechanism is provided for use with a pair of telescoping tubes. A locking mechanism releasably locks the inner tube relative to the outer tube for adjustment of table height. The locking mechanism includes a housing disposed at the lower end of the inner tube. A locking element with the housing is biased against an inclined ramp fixed within the housing and, though an opening in the housing, against the inner wall of the outer tube, thereby preventing the inner tube from moving downwardly within the outer tube. A push rod and arm, actuated by a handle near the platform, pushes the locking element away from the inner wall or the ramp which allows the inner tube to move downwardly.

Abstract: A self-contained electrostatic air filter assembly having two hinged rectangular frames into which is disposed rectangular polyester/wool filter dielectrics with a conducting charging screen in between. The polyester/wool dielectrics are charged through the conducting screen by a high voltage power supply having a low source resistance. The high voltage supply having a small source resistance is integrated into the air filter assembly and connected electrically to the conducting screen. High voltage is quickly dissipated from the screen and dielectrics when the unit is turned off by a specially designed bleeder resistor. As an air mass is forced through the filter, particulates in the air are removed electrostatically quickly and efficiently by the charged polyester/wool filter material. The air filter assembly has been shown to have a high particulate capacity.
