055307000 | FILTER OR APERTURED DEFLECTOR UNIT DISCONTINUOUS ACROSS GAS FLOW WITHIN FLOW CONDUIT | 11 |
20080196365 | Adjustable dual-blade dust filter using granular bed flow - A dust filter has adjustable sub-blades between blades. By adjusting the blades' distanced and the sub-blades positions and angles, stagnation area of filtration material on the blades are removed. Furthermore, space in the dust filter is fully used. Thus, a filtering efficiency is improved. | 08-21-2008 |
20100050579 | Filter housing structure of projector - A filter housing structure adapted to a projector having a first encircled hook-and-loop fastening layer, a housing, a filtering layer, and a second encircled hook-and-loop fastening layer is provided. The first encircled hook-and-loop fastening layer is fixed on the casing of the projector and surrounds the openings arrayed on the casing. The housing has a central portion and a boundary portion. The central portion has a plurality of through holes thereon corresponding to the openings of the casing. The boundary portion surrounds the central portion and is corresponding to the first encircled hook-and-loop fastening layer. The filtering layer is assembled in the central portion and is disposed between the through holes and the openings for shielding the through holes. The second encircled hook-and-loop fastening layer is fixed on the boundary portion for fastening the housing to the first encircled hook-and-loop fastening layer. | 03-04-2010 |
20110173934 | Disk-Shaped Gas Production Filter Elements - A filter element that includes a disk-shaped filter medium having an axially upstream surface, an axially downstream surface, and an outer peripheral surface extending axially therebetween. An embodiment of the filter medium has a radial inlet flow surface formed along the outer peripheral surface. Further, there is an inlet flow surface formed along the axially upstream surface, wherein a fluid is able to flow both radially and axially through the filter element. | 07-21-2011 |
20110203234 | DUST-CATCHER FOR BLAST FURNACE GAS - A conventional dust-catcher for blast furnace gas comprises a pressure vessel, with a gas inlet and outlet dome ( | 08-25-2011 |
20160184963 | DUST SHROUD WITH INTERNAL IMPELLER AND ADJUSTABLE MOUNTING MECHANISM - A dust collection system includes a dust shroud with an internal impeller and a restrictor plate which separates the impeller from a cutting attachment. The impeller and restrictor plate provide air flow from the cutting attachment, through the shroud, and out of an exhaust port such that the dust collection system may be used without a powered filter if desired. The dust shroud may include an attachment to an angle grinder with clamping arms pivotably attached to the top of the dust shroud body. The clamping arms move inwardly relative to the shroud body to accommodate different sizes of angle grinders. | 06-30-2016 |

20100077709 | FILTER INLET - The invention relates to a filter ( | 04-01-2010 |
20100251675 | SNAPBAND FILTER DESIGN FOR HORIZONTAL BOTTOM ACCESS COLLECTOR - A horizontal dust collector includes a plurality of elongated filter elements in a horizontally-oriented array, each filter element connected at one end to a tube sheet, and at an opposite end to a support plate. The one end of each filter element is fitted with a substantially rigid coupler having an insertion portion, a peripheral, outwardly facing groove adopted to receive a mating edge defining an aperture in the tube sheet, and a radially outwardly extending flange axially behind the annular groove for engagement with a filter element assembly tool. A tool is also provided to facilitate installation of the filter elements within the dust collector. | 10-07-2010 |
20100263338 | Reduced Restriction Air Filter - A filter assembly and filter element are provided utilizing a given volume of space effectively and efficiently with low restriction. An irregular shape filter is provided to fit the space, including a filter element circumscribing an inner plenum and having an axially extending sidewall. The sidewall has a differential axial height as it circumscribes the inner plenum. | 10-21-2010 |
20120090285 | PARTICLE COLLECTION DEVICE - A cartridge assembly includes a body portion ( | 04-19-2012 |
20130042585 | FILTER CORE FOR USE WITH PLEATED FILTER CARTRIDGES - A filter core includes a tubular body that has a first end and a second end. The tubular body includes a plurality of surface features spaced longitudinally along the tubular body between the first and second ends. Each of the surface features includes a first portion for flow area and a second portion for bridging across an opening for strength. | 02-21-2013 |
20130047562 | LIQUID KNOCKOUT DRUM - A device for removing moisture from a gas includes an elongated vessel having a gas outlet at a first end, a moisture outlet at a second end and a gas inlet located between the gas outlet and the moisture outlet. The elongated vessel includes first and second gas flow modifying elements for causing deviation of the flow of gas within the vessel from a flow path extending directly between the gas inlet and the gas outlet. The first gas flow modifying element is in the form of a plate extending partly across the vessel and arranged to direct the gas flow from the vessel in a direction towards the moisture outlet. The second gas flow modifying element is in the form of at least one plate extending | 02-28-2013 |
