Abstract:
A particle separation member is provided for use with a cyclone separator. The particle separation member divides the separator into a cyclone chamber and a particle receiving chamber. The cyclone chamber and the particle receiving chamber communicate via a plurality of apertures in the particle separation member. The apertures have baffle members for reducing the flow of fluid in the particle receiving chamber.
Abstract:
An upright vacuum cleaner has a vacuum cleaner head for cleaning a floor having a forward portion and two spaced apart rear portions extending rearwardly from the forward portion, the spaced apart rear portions defining an open space there between, and a longitudinally extending upper body portion having a longitudinal axis, the upper body portion being pivotally mounted on the vacuum cleaner head and moveable between a raised position and a lowered position in which the longitudinal axis is generally parallel to the floor, a portion of the upper body portion being received in the open space between the rear portions when in the lowered storage position.
Abstract:
A vacuum cleaner head is provided with cutting elements positioned in the air flow path of the vacuum cleaner head to reduce the size of elongate particulate material entering the dirty air inlet.
Abstract:
A method and apparatus for operating a pressure swing adsorption process having an adsorption zone is disclosed that may utilize only a single adsorption stage. The purge cycle is automatically commenced by a pressure build up in the enriched fluid vented from an adsorption zone.
Abstract:
A method and apparatus for operating a pressure swing adsorption process is disclosed that may utilize only a single adsorption stage yet still produce a continuous stream of a concentrated fluid.
Abstract:
A cyclonic separation device is provided having improved pressure loss characteristics. A fluid supply conduit in flow communication with an inlet to a cyclone is located and configured to extend longitudinally through a central portion of the cyclone, whereby the sharp bending of the conduit may be reduced, thereby reducing pressure losses in the device, without unduly interfering with the cyclonic flow within the cyclone. The present invention may be adapted for use with cyclonic separation devices of all types, including single- and multi-stage cyclonic separators.
Abstract:
A terminal insert for a cyclone separator for separating a material from a fluid. The terminal insert has a distinct member positioned within the cyclone separator to impinge upon at least a portion of the fluid as it rotates within the cyclone separator to destructively interfere with the rotational motion of the fluid within the cyclone separator.
Abstract:
A vacuum cleaner head has a rotatably mounted brush and a pressure sensor which is drivingly connected to the brush to move the brush with respect to the dirty air inlet in response to the air pressure in the air flow path to the vacuum cleaner head.
Abstract:
A process and reactor for chemical conversion is taught. The process allows the selective breaking of chemical bonds in a molecule by use of fast rise alternating current or fast rise pulsed direct current, each fast rise portion being selected to have a suitable voltage and frequency to break a selected chemical bond in a molecule. The reactor for carrying out such a process includes a chamber for containing the molecule and a generator for generating and applying the selected fast rise current.
Abstract:
A generator is taught which uses alternating current or pulsating direct current to produce ozone from oxygen. The generator comprises a high voltage and ground electrode separated to form a gap for accommodating a dielectric member and gas to be reacted. The generator includes many features which may be used alone or in combination to provide an energy efficient and safe apparatus.
