Luggage handling hand cart

Luggage handling hand cart with inlay pattern side panels and top

A luggage hand cart has a luggage supporting platform supported on wheels, with a pair of uprights extending upwardly from the platform at each end. The upper ends of the uprights are compoundly angled to extend inwardly relative to both the ends and sides of the platform and a pair of opposed, molded, generally Y-shaped plastic fittings, each having a base with a pair of projecting leg parts extending at a compound angle from the base outwardly relative to the sides and ends of the platform and downwardly, telescopically receive the upper ends of the uprights. The fittings each have internal wall structure and the longitudinally extending hanger rod then has its ends telescopically secured in the base portions of the fittings in abutting relation with internal wall structure head parts, while the upper ends of the uprights are secured in abutting relation with internal wall structure in the leg parts of the fittings.

An internally supported composite filter having a wire-like frame, two confronting sheets of filter media secured to the frame, a ring of adhesive at the center of the sheets secures their confronting faces together in a relatively uncompacted fashion, and a handle secured to the sheets proximate one of the corners of the frame which can be grasped by a workman to remove the filter from the mounting structure in a peel-away fashion.

Internally supported filter

A pocket filter cartridge for removing solid particulates from a dirty gas stream including a plurality of sheath-like filter bags suspended from a common header assembly in side-by-side relation. Each of the filter bags includes a plurality of alternating rows of filamentary stays or span stitching spaced across the width of the bag and extending generally parallel to one another along its length so that upon inflation of the bag by the dirty gas stream during use, the stays shape the bag into a plurality of adjacent tube-like sections opening into one another within the bag. The stays in each row are sized to be of a different length than the stays in the rows adjacent to it to alternately vary the thickness of the bag at the juncture of the tube-like sections formed in the bag.

Pocket filter assembly

A gas separation device has a peripheral flow-through frame with a sheet of gas separation filter media disposed across the frame and attached to the frame for filtering a gas stream passing through the filter media. As an aid in installing and removing the gas separation device from an installation, one advantageous embodiment has a handle centrally disposed of and attached to the filter media and projecting from one face of the filter media while another advantageous embodiment has two handles centrally disposed of and attached to the filter media and projecting from opposite faces of the filter media.
