    Abstract: A surface cleaning apparatus includes an air flow path, a filter housing, and a filter member in the filter housing. An air treatment member, a suction motor, and the filter housing are positioned in the air flow path. The filter member includes a plurality of individual filter elements arranged in parallel, each including porous filter material having at least one upstream face and at least one portion defining a porous filter media air outlet. The at least one upstream face has a larger surface area than the at least one portion. An outside gap is provided between at least some of the upstream faces and opposed facing walls of the filter housing, and an inside gap is provided between opposed upstream faces. A cross-sectional area of the outside gaps and the inside gaps is at least as large as a cross-sectional area of an air treatment member air inlet.

    Abstract: An apparatus for cutting a pipe has a base comprising a pipe support having at least one set of lower rollers and an upper frame supporting a cutting apparatus and at least one upper roller. The upper frame is moveable relative to the base between an open position in which the pipe may be inserted between the at least one set of lower rollers and the at least one upper roller, and a clamping position in which the pipe is in contact with the at least one set of lower rollers and the at least one upper roller. The cutting apparatus comprises a grooving member configured to provide an annular groove on an outer surface of the pipe, a cutting member configured to cut the pipe, and a chamfering member configured to provide a chamfer on the outer surface of the pipe between a location of the annular groove and a location of the cut in the pipe.

    Abstract: A surface cleaning apparatus has a cyclone chamber provided in an air flow path. The cyclone chamber has a screen assembly with an outlet section, a longitudinally spaced apart distal section and a longitudinally extending porous section. The outlet section includes a non-porous member extending longitudinally inwardly an outlet section length from an outlet end of the outlet section to a longitudinally inwardly positioned inlet end of the outlet section. The outlet end of the outlet section overlies a cyclone air outlet. The porous section extends longitudinally inwardly from an outlet end of the porous section that is located at the inlet end of the outlet section. The inlet end of the outlet section has a width in a direction transverse to the longitudinal direction that is greater than a width of the outlet end of the porous section in the transverse direction.
