Abstract: Method and apparatus for cleaning pollution control equipment, such as particulate removal devices, including wet electrostatic precipitators (WESP). The WESP may include a housing, at least one gas inlet in fluid communication with the housing, a gas outlet spaced from the at least one gas inlet and in fluid communication with the housing, one or more ionizing electrodes in the housing adapted to be connected to a high voltage source, and one or more collection electrodes in the housing. The housing may be in fluid communication with a flushing fluid source, such as a water source. The effective length of the collection electrodes is increased with extensions which add significant surface area to the collection electrodes while minimizing the corresponding height increase.

Abstract: Method and apparatus for cleaning pollution control equipment, such as particulate removal devices, including wet electrostatic precipitators (WESP). The apparatus may comprise a plenum having a gas inlet for the introduction of process gas into said housing; a gas outlet for discharge of treated process gas from said housing; at least one ionizing electrode; at least one particulate collection electrode; the plenum being in fluid communication with the at least one ionizing electrode and the at least one particulate collection electrode; an upper support frame; a lower support frame connected to the upper support frame and comprising at least one electrode support beam supporting the at least one ionizing electrode; and at least one movable nozzle in the plenum for discharging washing liquid towards the at least one collection electrode to dislodge particulate matter from the at least one collection electrode.

Abstract: Method and apparatus for cleaning pollution control equipment, such as particulate removal devices, including wet electrostatic precipitators (WESP). The apparatus may include a housing having a chamber, at least one process gas inlet in fluid communication with the chamber, a process gas outlet spaced from the at least one process gas inlet and in fluid communication with the chamber, one or more ionizing electrodes in the housing and one or more collection electrodes or plates in the housing. Sealing liquid is provided and introduced into the chamber in an amount sufficient to submerge the at least one process gas inlet and stop the flow of contaminated gas into the chamber.

Abstract: Wiring channel assignment in very large scale integrated (VLSI) bit stack macros is optimized for fixed macro placement and variable pin placement. Nets are first prioritized by length with the longest nets having highest priority. Nets are then routed between the appropriate macros according to their priority. Pin rails or position are assigned dynamically, rather than being predetermined, as the nets are being placed with a preference towards the nearest edge of the macro, in order to minimize net length and maximize sharing of wiring channels among multiple nets.

Abstract: Methods for detecting the mutation in the horse adult skeletal muscle sodium channel alpha-subunit gene that causes hyperkalaemic periodic paralysis in horses is provided based on a mutation in the sodium channel region IV, S.sub.3.
