Abstract: The gate housing has a flow passage therethrough, the flow passage having an inlet and an outlet. The gate housing also includes a gate pocket configured to receive a blast gate and to allow the blast gate to slide therein between an open position and a closed position. The magnetic brake element is on the gate housing and includes a magnet mounted to the gate housing such that a magnetic force of the magnet extends into the gate pocket.

Abstract: A negative-pressure dust collector system employs a dust separator device to separate the dust that is entrained in a stream of dust-laden air, exhausts the air stream to a vacuum-inducing machine, and discharge the separated dust downward into a bagger arrangement. The latter employs an open-bottom generally rigid hopper with a grid across its open bottom. A flexible dust collection bag is clamped onto an exterior of the hopper and hangs from the hopper. Under vacuum, the bag closes off the open bottom of said hopper. The grid has openings dimensioned so that dust in the container passes freely through the grid when the vacuum-inducing machine is shut off, but so that the bag may be sucked up against the grid, but not sucked into the open-bottom hopper when vacuum is applied. A flexible apron may be attached to the bottom of the hopper between the grid and the dust-collection bag.

Abstract: A bench-top dust collector has a front or intake side where air is directed by a cowling into a pre-filter and then a final filter that are held in a frame. A rear compartment holds an array of small high velocity fans that pull the air through the filters to a plenum in the rear compartment. The filtered air in the plenum is discharged through a grill in a downward and rearward direction. The unit is compact and configured to be about the size and shape of an attaché case.

Abstract: A sound absorbing filter for a dust collector system is attached downstream of the system air blower and ahead of the cylindrical HEPA filter cartridge. The sound filter is formed of a cylindrical barrel or shell, favorably steel, another metal, plastics, or composite with end-caps bonded on. The cylindrical shell interior is lined with plural annular layers of sound absorbing materials. The sound absorbing elements are retained with two or more thin retainer plates The lining can comprise a radial outer layer of compressed fiber batting, and a radial inner layer of convoluted acoustic polyurethane foam 1 to 2 inches thick. The foam lining protects the fiberglass from the air flow reducing fiber shedding, and also absorbs higher frequencies, with the fiberglass being more absorptive of lower frequencies.

Abstract: A bucket lid for a cyclone dust collector is configured to fit onto a standard pail or bucket, with a circumferential rim forming an outer edge of the lid, a central mounting disk onto which the cyclone is mounted, and a series of baffles extending circumferentially around the lid between the mounting disk and the rim. These baffles extend downward into the bucket to interfere with swirl in the bucket from dust discharged from the cyclone. The baffles may be radial ribs alternating with ramped coffers. The lid may be formed of anti-static polypropylene.

Abstract: A method of protecting a gas turbine component for operation in a high temperature environment that includes the gas turbine component including a substrate having a silicon-containing layer, wherein the gas turbine component has a curved surface; forming a flexible mask configured to cover the curved surface of the gas turbine component, the flexible mask including a plurality of slots disposed in a pattern; disposing the flexible mask in direct contact with the curved surface of the gas turbine component; applying a bondcoat onto the flexible mask and the gas turbine component, such that bondcoat fills the plurality of slots and contacts the curved surface; and removing the flexible mask by heat or chemical reaction, such that, after removing the flexible mask, the curved surface of the gas turbine component comprises a patterned bondcoat layer in the pattern defined by the flexible mask.
