Abstract: During the manufacture of bricks, either before or after such bricks are introduced to the kiln for drying, selected brick from spaced positions in at least some of the rows are mechanically displaced to corresponding positions in upstream, downstream, or otherwise adjacent rows to effect an inter-row movement of some, but fewer than all of the bricks in any particular row. According to the invention, the selected bricks may be either pushed, lifted, lowered or combinations thereof from one row and transferred to a different row. One translating device designed for this technique is a snaggle-tooth pusher which engages and pushes some, but not all of the bricks in a row or rows. The selected bricks may be initially separated from the other bricks by means of either the snaggle-tooth puller, or by means of a vertically movable support plate which operates in conjunction with a slotted support plate immediately thereabove to remove and lower selected brick.

Abstract: A replacable, sectionalized filter cartridge is received within a casing which is adapted to be inserted and removed from the nasal passage. The filter cartridge is preferably formed with two filter sections, one a nylon, cilia-like membrane, and one a polypropylene cilia-like membrane. If desired, in an alternate embodiment, a third honeycomb section separating the outer sections may be provided. The materials which form the outer filter sections are so chosen as to become electrostatically charged responsive to the movement of air thereby.
