  • Patent number: 9011579
    Abstract: This disclosure describes embodiments of an air treatment apparatus that stimulates formation of large moisture droplets from small moisture droplets found in air flowing in power generating systems to a turbo-machine. In one example, the embodiments generate a field that promotes contact between the smaller moisture droplets. This contact can increase the size of moisture droplets to facilitate condensation of moisture out of the air.

  • Publication number: 20140178667
    Abstract: An article comprising a microporous membrane. A first porous fabric is laminated to a first side of the microporous membrane. A second porous fabric is laminated to a second opposite side of the microporous membrane to form a laminate with the membrane and the first porous fabric. The laminate has two fabric sides separated by the microporous membrane. A treatment material is applied to the laminate to form a treated laminate. The treated laminate has an oil resistance of at least a number 7 determined by AATCC 118 testing on both fabric sides and has an air permeability through the treated laminate of at least 0.01 CFM per square foot determined by ASTM D737 testing.

  • Patent number: 8479371
    Abstract: A process and an associated assembly for supporting a porous media during a treatment which exposes the media to a fluid that modifies at least one property of the media. The assembly includes a supporting core. The media is wrapped in a plurality of layers about the core to form a first roll of the media. The assembly includes first securement mechanisms exerting diametrical pressure on the ends of the first roll to prevent fluid flow axially out of the ends of the first roll. An additional amount of the media is being wrapped in a plurality of layers about the first roll to form a second roll of the media. The assembly includes second securement mechanisms exerting diametrical pressure on the ends of the second roll to prevent fluid flow axially out of the ends of the second roll. The assembly may be part of equipment.

  • Patent number: 4770187
    Abstract: An apparatus for surgical aspiration and monitoring of the aspirated fluids includes a sealable aspiration bottle supported by an electronic weighing scale on a base stand. The bottle includes tubing connectors joined to a negative gauge pressure source and to an aspirating surgical instrument. A pair of electrodes extend into the bottle and are connected to an electronic circuit which measures the impedance of the fluid/tissue aspirate in the bottle. A microprocessor receives the impedance and net weight data of the aspirate, determines the relative amounts and net weights of fluid and tissue in the aspirate, and displays this information on a visual display.
