Cleaning devices are described which include a vacuum cleaner nozzle with a sharp rim for directing incoming air down against the floor; a vacuum cleaner wherein electrostatically charged brushes that brush dirt off a floor, are electrically grounded to remove charges that could tend to hold dirt to the brushes; a vacuum cleaner head having slots that form a pair of counter-rotating vortices, and that includes an outlet that blows a stream of air at the floor region which lies between the vortices; a cleaning device that sweeps a group of brushes against the ground along a first direction, and then sweeps them along the same ground area but in a second direction angled from the first by an amount such as 90. degree. , to sweep up particles lying in crevices extending along any direction; a device that gently cleans a surface to remove bacteria for analysis, including an inclined wall along which cleaning fluid flows onto the surface, a vacuum chamber for drawing in the cleaning fluid, and a dividing wall spaced slightly from the surface to separate the fluid source from the vacuum cleaner chamber; and a device for providing pulses of pressured air including a chamber to which pressured air is supplied, a ball that circulates around the chamber to repeatedly close an outlet, and an air source that directs air circumferentially to move the ball around the chamber.

A multi-vortical separator for removing particulate matter suspended in a transport medium is described. A single pressure sealed enclosure has a plurality of contoured columnar baffles symmetrically arranged in quadruplets, the baffles having cooperating saddle portions that define four vortical flow initiating flow splitters. The columnar portions of the baffles cooperate to define regions of rotating fluid wherein the transport medium rotates and particulate matter, suspended within the medium, is separated therefrom by centrifugal action. The separated particulate matter impinges on the columnar surfaces of the baffles and falls in a gravity fall manner into a collection bin. A plurality of vortex finder tubes, placed within the regions of rotating fluid, receives cleansed air from a central portion of the regions and guides it to the separator outlet.

A cyclone separator and an installation of such a separator in a processing vessel are set forth which conditions the inlet flow to prevent the depositing of particulates at the cyclone inlet. The separator is disposed in a cylindrical enclosure represented by the processing vessel. The enclosure has an inner surface and defines a chamber to receive the gas and entrained particulates. Disposed within the chamber is the smaller diameter cyclone separator having a cylindrical wall. To admit gas, the separator wall has an inlet, one side boundary of which is arranged tangential with the enclosure inner surface, the other side boundary being spaced from the surface to define an axially extending, scroll-shaped envelope between the enclosure inner surface, the cyclone wall and its inlet. A flow conditioning surface is provided between the vessel inner surface and cyclone wall, the flow conditioning surface having a trailing edge at the cyclone inlet and a leading edge to accelerate the gas flow preferably to a velocity or a range of velocities acceptable by the cyclone for efficient separation without the creation of wake turbulents, eddies or the like, which would result in the deposit of particulates at the cyclone separator unit. A flow directing surface may be disposed within the cyclone to turn the gas stream and impart an accelerated downward velocity to the particulates as they flow around the cyclone.
