Patent number: 6135367Abstract: An atomizing board includes a board surrounded by a peripheral frame that is configured to allow stacking of two atomizing boards. The board includes a number of atomizing holes defined therein. A periphery that defines each atomizing hole includes an annular upper wall extending upwardly therefrom and an annular lower wall extending downwardly therefrom. The atomizing holes are arranged in the board in a manner that they are asymmetrical to a central transverse axis of the board such that in two stacked atomizing boards consisting of an upper atomizing board and a lower atomizing board, one of the lower atomizing board and the upper atomizing board is in a status that is rotated through 180.degree. or turned upside-down relative to the other of the lower atomizing board and the upper atomizing board, and each atomizing hole on the upper atomizing board is partially aligned with at least one of the atomizing holes of the lower atomizing board.Type: GrantFiled: September 3, 1998Date of Patent: October 24, 2000Inventor: Tsung-Ming Hsu

Patent number: 6120573Abstract: A separation plate (10) includes a first surface (10a) and an opposing second surface. A plurality of teardrop-shaped virtual impactor projections (12) are provided on the first surface, preferably in a plurality of rows (13a, 13b, 13c). Each projection includes a convex leading profile (18) facing a fluid stream (16), and two concave side surfaces (19) that are positioned to define a tapered downstream portion. The convex leading profile may include a concave portion (20). The concave portion defines a virtual impact void therethrough. The virtual impact void defines a terminal end of a passageway that extends through the separation plate to communicate with the second surface. When particle-laden fluid is caused to flow along the first surface, a major portion of the fluid containing a minor portion of particles flows around the teardrop-shaped virtual impactor projections along the first surface.Type: GrantFiled: November 13, 1998Date of Patent: September 19, 2000Assignee: MesoSystems Technology, Inc.Inventors: Charles J. Call, Patrick T. Call, Vanessa M. Kenning, Joseph G. Birmingham, Donald J. Hammerstom

Patent number: 6110247Abstract: A plurality of micropillars (2) arranged in a plurality of rows (4, 6, 8) are provided. When a particle-laden fluid stream is caused to flow through the micropillars, at least a portion of the particles impacts and becomes deposited on the micropillars' surfaces while the fluid stream is deflected aside. The deposited particles may subsequently be collected.Type: GrantFiled: November 13, 1998Date of Patent: August 29, 2000Assignee: MesoSystems Technology, Inc.Inventors: Joseph G. Birmingham, Vanessa M. Kenning, Patrick T. Call, Charles J. Call

Patent number: 6101886Abstract: Atmospheric Samplers are disclosed using aerogel filter material. The samplers include one or more cascaded impact sample stations with discs of aerogel as the targets. Ambient air carrying particulate matter is introduced into the sampler and the particles are captured by the aerogel in its pore structure. In certain embodiments, the aerogel filter is next transported to a position where it is fragmented by a spray of water. The fragmented aerogel and the captured particles are transported in the fragmenting water from the sampler for analysis. In one embodiment, the sampler is segmented with alternate nozzle and filter segments for easy assembly, sampling and disassembly for analysis of the captured particles in aerogel filters positions below the nozzles.Type: GrantFiled: November 25, 1998Date of Patent: August 15, 2000Assignees: Pacific Sierra Research, University of Virginia Patent FoundationInventors: Jack S. Brenizer, Charles E. Daitch, Bouvard Hosticka, L. Roger Mason, Jr., Pamela M. Norris

Patent number: 6048376Abstract: A separator tank for removing oil from a gas/oil mixture includes a lower chamber for collecting the oil removed from the gas/oil mixture, an intermediate chamber overlying the lower chamber and an upper chamber overlying the intermediate chamber. The separator tank has an inlet in fluid communication with the intermediate chamber for introducing the gas/oil mixture into the separator tank at a velocity. The intermediate chamber includes a baffle adapted for changing the velocity of the gas/oil mixture as the mixture travels between the inlet and the upper chamber for causing at least some of the oil to separate from the gas/oil mixture. The upper chamber has a diffusing element for reducing the velocity of the gas/oil mixture and an oil coalescing element for separating at least some of the oil from the gas/oil mixture.Type: GrantFiled: August 3, 1998Date of Patent: April 11, 2000Assignee: Ingersoll-Rand CompanyInventor: David B.
