Abstract:
A surface cleaning apparatus comprises an air flow passage extending from a dirty air inlet to a clean air outlet and a suction motor. The surface cleaning apparatus may also comprise a cyclone chamber provided in the air flow passage. The cyclone chamber may comprise a cyclone air inlet, a cyclone air outlet and a dirt outlet. The surface cleaning apparatus may comprise a dirt collection chamber having a dirt inlet, a dirt collection chamber first end, an opposed dirt collection chamber second end and a longitudinally extending sidewall. Various design improvements are provided.
Abstract:
A surface cleaning apparatus comprises a filtration apparatus comprising a cyclone downstream from the dirty air inlet and an openable filtration chamber comprising a screen downstream from the cyclone and upstream from the suction motor. The filtration chamber is accordingly a separate volume to that of the cyclone chamber and accordingly may be accessed to clean the screen independently of opening the cyclone chamber.
Abstract:
A surface cleaning apparatus comprises a cyclone having a dirt outlet with an impingement surface positioned in a dirt collection chamber and spaced up to 50 mm, preferably from 8 to 30 mm, from the dirt outlet.
Abstract:
A cyclonic surface cleaning apparatus incorporates a series of sequential physical filtration members to progressively remove smaller particulate matter whereby the physical filtration members collectively have a longer in use time prior to being clogged, thereby permitting a longer operating time prior to the cleaning or replacement of the physical filtration members.
Abstract:
A consumer appliance comprises a source of humidified hydrogen; and, a combustion zone in fluid flow communication with a source of oxygen and the source of humidified hydrogen. A method of producing a visible hydrogen flame comprising providing water with hydrogen gas is also provided.
Abstract:
A method of forming an image on a substrate, the substrate having a front face, the method comprising acquiring electronic data representing a work image of an object, the work image including a three dimensional representation of the object; using the electronic data to prepare a three dimensional reproduction of the object on the substrate wherein the substrate is shaped and the selection of the front face bearing a positive or a negative of the work image is made so that the three dimensional representation has a holographic appearance.
Abstract:
A watercraft includes a number of subassemblies, including an inflatable hull (8), a drive system (2), a battery, a seat assembly (24) and a steering (5) and thrust control. Each of the subassemblies of may be of one or more particular designs which are detailed herein. A watercraft in accordance with the teaching herein may use one or more of these designs and each such watercraft is within the scope of this disclosure.
Abstract:
A residential method for treating water with an ozidizing gas operates under elevated pressure. The elevated pressure is obtained by means of a pressurized oxidizing gas source (e.g. 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 (e.g. bubbles from about 1 mu to about 20 mu in diameter) in a liquid.

Abstract:
An electricity conducting cord has first and second ends, one of the ends comprising an electrical connection member engageable with a power connection member of an apparatus having an apparatus power rating, at least one of the power connection member and the electrical connection member comprising electrical connectors and a physical cord identification member, the physical cord identification member is configured to inhibit the electricity conducting cord being electrically connected to the power connection member if the electricity conducting cord has a power rating lower than the apparatus power rating.
