The suction end of the nozzle has a flexible tapered opening that is radially collapsible and foldable in one or more axial directions that can conform to various shapes. The tapered opening may include a rim that extends coplanar to a vacuumable surface. The suction end is capable of beating up and down on a vacuumable surface when operated with a vacuum.

Abstract: A floor cleaning device includes a floor covering compartment having a cleaning opening, a vacuum generating device, a suction pipe that connects the floor covering compartment to the vacuum generating device so that suction force is applied on the surface covered by the cleaning opening, a cleaning head body that holds the floor covering compartment, and a vibrating device that causes vibration of the floor covering compartment relative to the cleaning head body. The periphery of the cleaning opening is adapted to contact a surface to be cleaned so that a sealed cleaning space is formed inside the floor covering compartment and over the portion of the surface covered by the cleaning opening. Strong negative pressure is built up in the sealed cleaning space to enhance suction efficiency. Vibration temporarily breaks the sealed state to facilitate moving of the floor covering compartment.

Abstract: Apparatus for cleaning residual toner and paper fiber residue from a biased transfer roll (BTR) in an electrophotographic apparatus using high velocity air and substantially contactless flexible biased conductive shims. The high velocity air flow between the BTR and two thin conductive flex-shims is created by means of a blower that evacuates the air in the cleaner housing vacuum chamber. The high velocity air, in combination with the electrically biased BTR and flex-shims, removes residue from the BTR surface and carries it into the vacuum chamber and deposits the residue in a filter bag. The BTR biased shim cleaner system is low cost, efficient and significantly smaller than current BTR cleaning devices.

The vacuum nozzles are propelled through a drive mechanism which moves each vacuum nozzle out of phase with the movement of every other nozzle. Cleaning fluid discharge members associated and movable with each vacuum nozzle direct cleaning fluid onto the carpet adjacent their respective vacuum nozzles.

Abstract: Vehicle drying apparatus for use in either roll-over, drive-through, or tunnel type car washing installations. The dryer comprises an air plenum tube which extends overhead and transversely of the drying location and has a plurality of air outlet nozzles, the angular orientations of which relative to a vehicle being dried is subject to alteration. Means are provided for pivoting the nozzles transversely of the vehicle and, in the case of the roll-over washer, reaiming the nozzles so as to constantly direct air in a forward direction regardless of the direction of movement of the gantry frame relative to the vehicle.

Abstract: The cleaning apparatus is formed by a housing member adapted to be inserted into an air duct and which has two spaced apart ports for providing an air flow path through the housing member. A flexible hose has one end coupled to one of the ports and is employed for moving the housing member in the air duct and for providing a passage for the flow of air from or to the housing member. A turbine formed by blades fixedly connected to a shaft is supported within the housing member for rotation about the shaft upon passage of air through the housing member by way of the two ports. An off centered weight is coupled to the shaft for rotation with the turbine for causing the turbine and hence the housing member to vibrate upon rotation of the turbine whereby the housing member may vibrate against the inside wall of the air duct to loosen dust and other matter from in the duct and to facilitate movement of the housing member in the duct.

Abstract: A ribbon of flexible fabric (e.g., nylon) is folded and riveted near the fold to form an attachment loop. The loop is then coupled on a centrally located support rod inside an air duct, the ribbon ends extending beyond the exit of the duct. When air is forced through the duct, the free ends oscillate rapidly to brush away particulates on a surface being cleaned. The support rod is a portion of a clip which is removably coupled to the duct. The duct is cylindrical and may comprise a common, commercially available vacuum cleaner tube.
