Abstract:
A household appliance incorporating an electrolyzer for electrolysis of water to H 2 and O 2 and an electrolyzer therefor. The appliance may include a burner for the hydrogen produced and an electric conductive member to provide household current to the electrolyzer. The electrolyzer comprises an outer housing defining a chamber which houses at least one cathode and at least one anode. The electrolyzer may comprise a plurality of field electrodes and the field electrodes may comprise first and second field electrodes which are electrically connected together and spaced apart to define an intra cell gap. Field electrodes may then be spaced apart to define an inter cell gap between electrodes of adjacent field electrodes. At least one of the anode and cathode may be connected to an electrically conductive member that is molded in situ in the housing and at least some of the electrodes may be configured to dimensionally stabilize the electrodes during operation of the electrolyzer. The number of field electrodes may be from 40 to 60 if a voltage of 120 V is supplied to the electrolyzer, 80 to 120 if the voltage is 240 V, or 4 to 6 if the voltage is 12 V. The gap between adjacent electrodes may vary between top and bottom and the electrolyzer may incorporate a plastic heat sink.

Abstract:
A method for treating a liquid (e.g. water) with a gas (e.g. air) containing ozone includes passing air through a corona discharge ozone generator to produce air containing ozone and introducing the air containing ozone into the liquid; passing air through the ozone generator, and, periodically altering the concentration of ozone produced by the ozone generator by periodically de-energizing the ozone generator or changing the air flow rate through the ozone generator.
Abstract:
A heat engine has a region within which a working fluid travels and an hydraulic fluid provided in a reservoir and the output from the heat engine drives the movement of the hydraulic fluid.
Abstract:
An apparatus and 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 (32) to obtain a partially cleaned air sream and subjecting the partially cleaned air stream to an electronic filtration stage (50) and optionally a second cyclonic separation stage (60) to obtain the clean air stream. The electronic filtration stage (50) is optionally removable with a cyclonic cleaning stage from the vacuum cleaner. The electronic filtration stage (50) is optionally an electrostatic precipitator which utilizes air flow through the vacuum cleaner to generate the voltage used by the electrostatic precipitator.
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 (500) for carrying out such a process includes a chamber (514) 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 (212) and ground electrode (210) separated to form a gap (18) for accommodating a dielectric member (214) 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.
Abstract:
An upright surface cleaning apparatus is provided wherein the upper section is provided with an openable post motor filter housing. The post motor filter may be axially removable and may be positioned below the suction motor.
Abstract:
A surface cleaning apparatus comprises an air flow path extending from a dirty air inlet to a clean air outlet and includes a suction motor. The surface cleaning apparatus may be battery powered and/or may have a power requirement of 200 Watts or less. A cyclone chamber is provided in the air flow path and has an air outlet which is covered by a screen. In one embodiment, there is an absence of a vortex finder. In another embodiment, a vortex finder that extends into the cyclone chamber less than the height of the cyclone inlet and optionally less than the height of the cyclone inlet may be provided.
