Abstract: A lid-opening apparatus for a dust collector includes a base installed on a lid, a controller connected on the base, a cord defining a first end associated with a conduit and a second end associated with the frame, and a limiting member associated with the cord and between the first end and the second end of the cord. The controller can be rotated to a first position and a second position. While the controller is in the first position, the cord is in a loose condition, a flexible portion of the conduit is stretched, and the lid seals the container. While the controller is in the second position, the cord is in a tight condition, the flexible portion of the conduit shortens, and the lid leaves the container.

Abstract: A separation housing houses a rotor with multiple suspension chambers. Each chamber has a radially extending web portion between two rotating discs. An orifice is provided through the radially extending web portion. Another web portion urges gas radially out of the rotor. Passages through the rotating disks permit entry of gas and solid particle mixtures into the suspension chambers at high speed traveling toward each other in a suspension adjacent to the orifice. The web portion that urges gas out of the chamber pulls gas away from the suspension zone. Gas moving through the aperture and into a clean gas chamber pulls gas in the opposite direction. The result is gas in the suspension zone being fixed relative to the rotor or changing direction. Centrifugal force moves solid particles radially out of the chamber.

A reinforcement plate (17) is arranged in the area between the filter medium and the rings (14, 15). The end surfaces (18, 19) of the rings (14, 15) are supported by the grooves (20, 21) of a filter element housing, the grooves running radially.

Abstract: A low-microcracked porous cordierite honeycomb ceramic particulate filter having a high strength in combination with a very low pressure drop, a very high filtration efficiency, and a high thermal shock resistance. Little or no microcracking, a fine median pore diameter, and a narrow pore size distribution contribute to high strength. A thin channel wall, high wall permeability, and narrow pore size distribution, contribute to low pressure drop. A fine pore diameter and narrow pore size distribution with a minimum of coarse pores contribute to high filtration efficiency. A high strain tolerance, MOR/E, contributes to high thermal shock resistance. Particulate filters disclosed herein can be useful as a hot gas particulate filter, and particularly as an internal combustion engine exhaust gas particulate filter, such as an exhaust gas filter for a gasoline direct injection engine.
