  • Patent number: 5438729
    Abstract: A cleaner for air distributing duct systems of buildings has a motor driven fan for developing a vacuum for the suction of contaminants and air from the interior of the ducts and for forcing the obtained contaminated air stream under positive pressure, relative to the ambient, through multiple stages of filtration. The filtered air is discharged locally within the building. Measurement and display of the vacuum and prefilter air pressures indicate to an attendant the status of the cleaner operation and the condition of the air filters. A viewing window allows observation of the contaminated air stream and the prefilter. A pneumatically driven agitator of multiple whips is introduced into the duct system to dislodge adhering contaminants from the interior walls of the ducts. The vertical stacking of modular subunits gives access for servicing each stage of filters and provides roll-about portability of the cleaner.

  • Patent number: 5432975
    Abstract: A portable, compact and self-contained continuous flow recycling system includes a housing to accommodate a vacuum motor and liquid pump for recirculating a liquid cleaning solution and air. A pair of wheels supports the housing for tilting about a wheel axle. A pair of support arms are mounted to rotate on the axle, and their opposite ends are fixed to the shell of a cleaning head. The head is shaped to define a first compartment for receiving atomized cleaning solution and air, and a second compartment. A vacuum source draws the solution and air from the first chamber, across a partition near the floor, into the second compartment. The head is free to travel in an arcuate path relative to the housing, with its orientation determined by the arms, to insure a desired coplanarity with the floor or other surface being cleaned, when the head is in its operating position.

  • Patent number: 5426812
    Abstract: A device for cleaning chimney flues or like passageways comprises a multiplicity of generally planar strips of flexible, resilient plastic sheet material each having a length several times greater than its width, the strips having their central areas secured together so that their outer end areas extend radially from the centre, the central areas having a mounting for fixing to a flexible cleaning rod. The strips each have a rounded end and are disposed in overlapping but slidable relationship to each other so that their ends define a circle when viewed along the axis of the device. The flexibility of the elements and the fixing and mounting arrangement are such that the device can be pushed through a passageway considerably smaller in diameter than the length of the strips. The strip ends perform a scraping action, and are not substantially deflected sideways.

  • Patent number: 5419006
    Abstract: An exhauster fan system for a road sweeping machine comprises a rotatable fan, a drive, and a hydrostatic transmission system coupled between the drive and a spindle on which the fan is mounted. The output of the transmission system is controlled to apply a constant torque to the fan spindle. The transmission system comprises a variable displacement pump coupled to drive a fixed displacement motor. A pressure control is associated with the pump to control hydraulic oil flow in the pump to sustain a set pressure in the motor. The pressure control is selectively operable to provide different set pressures to the motor for different operating conditions. The fan is used in the environment of a road sweeping vehicle comprising a chassis, an airtight container mounted on the chassis, at least one suction conduit connected to the container and, positioned within the container, the described exhauster fan system in which the fan creates a high velocity air flow within the suction conduit.
