Abstract: A device includes a tank configured to contain a quantity of water; a pump configured to extract water from the tank and to pressurize the water; a connector in fluid communication with the tank and coupled to the tank so as to receive pressurized water produced by the tank and convey the pressurized water through the connector; and a plurality of lances configured to be interchangeably coupled to the connector to receive the pressurized water from the connector and to expel the water, wherein the plurality of lances includes a fog lance including a fog nozzle having an aperture that is sized from 0.35 mm to 0.45 mm, wherein the fog nozzle (a) includes a fog piston configured to cause rotational movement of water passing therethrough, (b) produces a flow rate of less than 0.17 liters per minute, and (c) produces an output that travels at least 1 meter.

Abstract: A wet/dry vacuum cleaner having a cover closing off the upper end of the vacuum cleaner, a lid connected to the cover having a collector extending into the lid and a filter assembly extending downwardly from the collector into water tank, the lid having an exhaust port for the vacuum cleaner communicating with a exterior thereof. A volute is disposed internally of the lid and coupled to the exhaust port, the volute being generally horizontally mounted in the lid forming a flat volute for accumulating air flow.

Abstract: A cleaner spotter tool for a wet/dry vacuum cleaner having a fluid containing tank, an extractor nozzle housing coupled to the tank, a fluid delivery pump mounted in the nozzle housing, a tubing fluidly coupled to both the tank and the pump for delivering fluid from the tank to the pump, and a spray nozzle on the nozzle housing coupled to the pump for spraying fluid out of the pump.

Abstract: Methods and systems for stairways or other walkways supported at only one end provide a plurality of stair treads are attached to a support beam, a pair of mounting brackets disposed at either side of a support beam bottom end rotatably connected to the support beam by a pivot bolt, the mounting brackets connected to a base, the base connected to a load bearing structure. A support bolt is disposed through the mounting brackets and below a bottom surface of the support beam. Locking means pivotally connected to the support beam engage a base mounting plate and restrain the stairway from at least one of pivoting upward about the pivot bolt or pivoting downward about the pivot bolt. Operative loads transfer from the support beam into the support brackets through the pivot bolt and support bolt and through the base into the load bearing structure.

Abstract: A carousel like unit for the storage of floppy disks and other electronic media such as cassette tapes, compact disks, and video tapes. The storage unit rotates about a vertical axis and uses an indexer to select desired storage compartments.

Abstract: A system for distributing a single stream of plastic into a multiplicity of streams is disclosed. The system includes two members, a plastic receiving member and a plastic discharge member. The receiving and discharge members are connectable in telescoping relationship. The receiving member has a central plastic receiving opening and a plurality of channels extending from said opening. The discharge member has a like number of passages communicating with the channels and terminating in discharge openings adapted to communicate with a mold. Also, internal heaters are provided to heat the plastic.
