Abstract: A cyclonic dust collector arrangement employs a cyclone that has a conic body formed of a conic wall. An upper divider plate closes off the upper end of the conic body, with a vortex tube descending from a central passage in the divider plate. The conic body has a narrow nose at a lower end so that the upper divider plate and the lower nose define a cyclonic chamber within the conic body. The inlet conduit penetrates the conic wall below the divider plate. The fan chamber of the separator is mounted above the divider plate, and serves to induce air flow from the inlet conduit into the cyclonic chamber, and through said vortex tube into the fan chamber. The air is discharged through a final filter. This construction has reduced manufacture costs and improved dust separation.

Abstract: A method and/or system for a breathable air safety system for both emergency and civilian personnel are disclosed. In one embodiment, a safety system includes a supply unit of a structure to facilitate delivery of a breathable air from a source of compressed air to an air distribution system of the structure, a civilian air supply enclosure of the structure to provide a civilian pressure of the breathable air such that the civilian pressure is suitable for direct human consumption through a civilian breathable air apparatus coupled with the civilian air supply enclosure, a firefighter air supply enclosure of the structure to provide a high-pressure of the breathable air such that the high-pressure is suitable to fill the breathable air in a firefighter breathable air apparatus through a RIC/UAC connector of the fill panel and/or a CGA connector.

Abstract: An air discharge apparatus such as an air nozzle manifold comprises an elongated air distribution enclosure having an air supply inlet and an elongated air discharge slot. There is at least one removable insert, and generally multiple removeable inserts in the discharge slot. At least one of the inserts has a discharge opening for discharge of air from the enclosure where air can pass through the slots substantially only through the discharge openings.

Abstract: A cushion system for a washing/bathing tub, comprises a cushion member having an abutment surface adapted to offer support to a user person in the tub. Magnet members are connected to the cushion. The magnet members are adapted to attractingly connect to a surface of the tub to maintain the cushion member in position against the surface of the tub.

Abstract: A method for providing a cushion and tub assembly is provided and comprises obtaining a cushion with magnets within the cushion. The method also comprises obtaining a metallic member, the metallic member magnetically attracting to the magnets in the cushion. The metallic member is permanently secured to a hidden surface of a tub at a location corresponding to a desired location of the cushion on the exposed surface of the tub. The tub and cushion are provided with a cushion being releasably connectable to the exposed surface of the tub at the desired location by attraction forces between the magnets and the metallic member through the tub wall.

Abstract: An electrically conductive confined space ventilation conduit formed of a substantially rigid non-metallic conductive material, such as plastic, and a related process for ventilating an enclosure accessed by a manhole or other port. In one embodiment, the conduit has a pair of outer cylindrical sections and a central section having a cross-sectional shape of a crescent or a segment of a circle where it passes through a port to provide a minimum of obstruction for men and equipment passing through the port. Intermediate sections of varying cross-section connect the central section to the cylindrical outer sections so that the outer sections are offset from the axis of the manhole. The central section is preferably configured to obstruct no more than about 10 percent of a standard manhole opening, while causing either no air flow rate reduction, or a reduction of no more than about 10 percent as compared to the flow rate through a cylindrical conduit similar to said outer sections.
