Abstract: Methods using vane electrostatic precipitators collect charged and uncharged particles with vane assemblies that are physically arranged to reduce the air flow rate to at or below 1.0 ft/sec (0.305 m/sec). In preferred embodiments, the main entrained air is divided into smaller proportions by using a plurality of vane assemblies in a vane electrostatic precipitator operating at a specific angle that have discharge electrodes in front of the vanes. This results in both the particles being charged and the flow rate of the air and articles being reduced as they traverse between vanes and over the vane surface. The vane width, operating angle, vane length and vane offset are designed to reduce the air flow rate. As a result, at the ends of the vanes, a high percentage of the air flow is less than 1 ft/s. This allows the particles that are discharged from the vanes during operation to fall by gravity and in the direction of lower air flow, resulting in extremely low re-entrainment and efficient particle collection.

Abstract: The embodiments described herein improve on the present electrostatic precipitator method of using parallel plates to collect particulates by using multiple parallel vanes set at operating parameters described below. By using vanes, the main entrained air is subdivided and directed to flow between vanes that induce resistance to flow allowing charged particles to collect on the vanes. The width of the vane is designed to be wide enough so the air flow rate at the ends of the vanes is less than 1 ft/s, allowing particles discharged from the plates to fall by gravity and in the direction of very low air flow, resulting in extremely low re-entrainment and efficient particle collection. Using vanes also allows for higher operating air velocities resulting in a smaller equipment foot print.

Abstract: An electrostatic sieve having a circular solid electrode, preferably with sawtooth contours arranged on its lower side concentrically around a center hole. The solid electrode is supported by insulating brackets around its perimeter. The brackets are attached to a conical outer structure, which also serves to collect the coarse particles. Underneath the solid electrode, with a gap between, is the sieve electrode, which is supported by a stretcher, preferably a circular ring of tubing with a square cross-section, itself supported on insulating brackets, which rest on an inner cone. The inner cone tapers toward the bottom to collect the fine powder passing through the sieve electrode, which passes through the hole in the bottom of the cone and falls into a collecting tray. The outer surface of the inner cone forms the inner surface of a conical passage, the outer surface of which is the outer conical support. Powder to be sieved is fed into the opening in the center of the solid electrode. As the powder passes through the hole into the gap between the solid electrode and the sieve electrode, it flows radially outward toward the perimeter of the electrodes under the influence of an electric field between the solid and sieve electrodes, and is induced to oscillate between the electrodes. As the particles flow outward, they are tried against the sieve electrode, and the finer particles flow through the sieve and down into the inner cone, passing out of the cone through the bottom and falling into the fines collection tray. The coarser particles continue to flow radially outward, oscillating and being tried all the way, until they finally flow off the perimeter of the sieve electrode and into the conical outer support. The coarse particles then flow through the gap between the inner and outer cones until they pass out of the bottom of the outer conical support into a donut-shaped collection tray. The contouring of the solid electrode causes increased oscillation as the particles move radially outward, which increases the number of trials against the sieve electrode. If required by the powder used, vibrators may be attached to the inner or outer cones to aid in passage of the particles along the walls of the cones.

Abstract: An apparatus for classifying particles by size comprising: a source of direct potential having first and second terminals, a sieve electrode connected to the first terminal, a solid electrode connected to the second terminal. Particles are fed to a transfer point located between the sieve electrode and the solid electrode such that the particles disperse and oscillate between the sieve electrode and the solid electrode whereby smaller particles pass through the sieve electrode. The new equipment has five adjustable operating parameters, screen angle, spacing between electrodes, field strength, powder input rate and electrode taper. The taper between electrodes is usually small, 0.3 to 0.4 of a degree with the larger opening at the top. The taper is used when the input powder is fine and the particle size differential is skewed either towards the high or low side. The purpose of the taper is to reduce the possibility of arcing at the input as well as to control dispersion of the particles. The solid electrode may be flat, or contoured in side-to-side sine wave, step or sawtooth patterns, or in dimples across the surface, to increase the oscillation of particles. A plurality of parallel wire electrodes may be added perpendicular to the long axis of the sieve and solid electrodes at the same potential as the solid electrode in order to increase turbulence and particle oscillation.

Abstract: A data processing system having a direct memory access controller (DMAC) which can be interrupted with a prioritized signal to vary bus mastership of a communication bus in the system. A prioritized interrupt signal is sent to a CPU when the DMAC has bus mastership. The CPU only informs the DMAC of the highest priority cumulative interrupt priority. With the use of a mask value, the interrupt may be selectively screened by the DMAC so that selective interrupts may remove bus mastership from the DMAC.

Abstract: A 1000 watt arc discharge arc tube assembly comprises two series connected side-by-side arc discharge tubes whose combined break down voltage in sufficient for a standard 2-5 kv starting pulse to simultaneously start both arc tubes without additional structure. A standard ballast, starter and fixture can be used with the arc tube assembly whose overall length is less than 300 millimeters. The lamps are spaced sufficiently apart to preclude detrimental heat transfer effects on one another and sufficiently close to act as a single source of light in standard fixtures normally employing lamps having a single discharge tube.

Abstract: A vane electrostatic precipitator (VEP) controls the air flow so that the entrained air particles are continuously subjected to a stress in the form of drag as they flow in front and behind vanes electrodes in the precipitator. It is not based on achieving laminar air flow over the collecting plates. Instead, efficient collection is achieved by operating with a narrow air stream and using vane electrodes in various configurations with porous back plates that gradually reduce the flow rate of the entrained air thereby allowing the particles to precipitate and collect on the vanes.
