A vacuum cleaner is provided having improved pressure loss characteristics. A fluid supply conduit in flow communication with an inlet to a cyclone is integrally formed as part of a cyclone bin. The present invention may be adapted for use with cyclonic separation devices of all types, including single- and multi-stage cyclonic separators.

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.

Process and apparatus for chemical conversion

The present invention is directed to methods and apparatus that use electrostatic and/or electromagnetic fields to enhance the process of spray forming preforms or powders. The present invention also describes methods and apparatus for atomization and heat transfer with non-equilibrium plasmas. The present invention is also directed to articles, particularly for use in gas turbine engines, produced by the methods of the invention.

Methods and apparatus for spray forming, atomization and heat transfer

A method for filtering a dirty air stream in a vacuum cleaner to obtain a clean air stream comprises subjecting the dirty air stream to a first cyclonic separation stage to obtain a partially cleaned air stream and subjecting the partially cleaned air stream to an electronic filtration stage and optionally a second cyclonic separation stage to obtain the clean air stream. The electronic filtration stage is optionally removable with a cyclonic cleaning stage from the vacuum cleaner. The electronic filtration stage is optionally an electrostatic precipitator which utilizes air flow through the vacuum cleaner to generate the voltage used by the electrostatic precipitator.

Vacuum cleaner

A vacuum cleaner has a first cyclonic cleaning stage and a second cyclonic stage positioned in series with the first cyclonic cleaning stage. The second cyclonic stage comprises a plurality of second stage cyclones. A passage connects the first cyclonic cleaning stage outlet and the second stage cyclones inlets. The passage does not increase in cross-sectional area in a downstream direction.

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. The cyclonic separation device may be incorporated in a vacuum cleaner such as an upright vacuum cleaner. A three dimensional conduit which is optionally used with a cyclonic separator is provided.

A cyclone separator having an improved efficiency to remove a broader spectrum of contained particles is disclosed. The inner wall of the cyclone separator is configured to continuously impart changes in the acceleration of a fluid as it rotates within the cyclone cavity.

A residential method for treating water with an oxidizing gas operates under elevated pressure. The elevated pressure is obtained by means of a pressurized oxidizing gas source (eg. an air pump) or a Prandtl layer turbine. The elevated pressure of the treated water is optionally used to dispense the treated water. The Prandtl layer turbine may be used to obtain particularly fine bubbles of a gas (eg. bubbles from about 1&mgr; to about 20&mgr; in diameter) in a liquid.
