Abstract:

A hair blower has an interior space, an air inlet, an air outlet and a fan assembly for directing air to flow from the air inlet to the air outlet. A positive ion emitter is operable to emit positive ions in the interior space for entrainment in the air upstream of the air outlet. A negative ion emitter in the interior space of the housing is separate from the positive ion emitter and is operable to emit negative ions for entrainment in the air upstream of the air outlet. A switch assembly allows selective operation of the hair blower between a negative ion mode in which the negative ion emitter is operated to emit negative ions and the positive ion emitter is inoperable, and a positive ion mode in which the positive ion emitter is operated to emit positive ions and the negative ion emitter is inoperable.

Abstract:

An escalator step includes a side plate co-extensive with and flushly affixed to each side wall of the step and presents a planar outer face adapted to travel juxtaposed the planar inner surface of escalator skirt panels. Tie rods retain each pair of side plates on a step and include end portions fully disposed within counterbores formed in the side plates whereupon friction-attached fasteners maintain the side panels inwardly against the respective step side walls.
