Abstract:
Apparatus for the recovery of water vapour from atmospheric air, for condensation into liquid water and having a housing for passage of air, a water vapour adsorbent cell in the housing to adsorb water vapour from air passing therethrough, inlet and outlet openings in the housing, so that air can be introduced through the inlet and passed through the adsorbent cell, and exited through the outlet, a cell fan for passing air through the adsorbent cell, closures for closing and opening the openings, a cell heat exchanger incorporated in the adsorbent cell, so that heat generated by the adsorption of water vapour from air may be transferred so as to maintain the temperature of the adsorption cell substantially constant within a predetermined range during adsorption, a radiator connected to the cell heat exchanger means, for disposing of heat transferred from the cell, a heating element associated with the adsorbent cell, and operable so as to heat the cell to remove water vapour, a condensing heat exchanger to receive heated air carrying water vapour from the adsorption cell and chill it so as to condense that water vapour in the air.
Abstract:
A surface cleaning apparatus has a unit that is self contained and has a shoulder strap reel containing a shoulder strap that is manually or automatically deployable or withdrawable.
Abstract:
An upright surface cleaning apparatus is disclosed. Embodiments of the apparatus comprise a surface cleaning head having a dirty fluid inlet. A fluid flow path extends from the dirty fluid inlet to a clean air outlet, and includes a suction motor and at least one cleaning stage. An upright section is mounted to the surface cleaning head and comprises at least one cleaning stage having an inlet. An above floor cleaning wand is connectable to the fluid flow path and has an inlet end. A valve is operable between a first position in which the surface cleaning head is in fluid flow communication with the at least one cleaning stage and a second position in which the above floor cleaning wand is in fluid flow communication with the at least one cleaning stage. In some embodiments, the valve is positioned adjacent the inlet of the at least one cleaning stage.
Abstract:
A surface cleaning apparatus is disclosed. Some embodiments of the surface cleaning apparatus comprise at least first and second adjacent housings, each housing having an upper portion. At least one openable lid is provided on the upper portions. The lid has an inner surface. A fluid flow path extends from a dirty fluid inlet to a clean air outlet of the surface cleaning apparatus and includes a suction motor. An air flow passage from the first housing to the second housing forming part of the fluid flow path and defined as a volume between the inner surface of the lid and the upper portions of the first and second housings. When the lid is opened, the airflow passage is accessible.
Abstract:
A surface cleaning apparatus comprises a dirt inlet, a handle, a cyclonic cleaning unit comprising a plurality of cyclones and at least one dirt collection chamber, each of the plurality of cyclones having an outer wall, an interior, a fluid inlet downstream from the dirt inlet and a fluid outlet, the at least one dirt collection chamber having an outer wall and an interior, wherein the surface cleaning apparatus is constructed such that the interior of the at least one dirt collection chamber is visible from a position exterior to the surface cleaning apparatus and a fluid flow motor. The surface cleaning apparatus may have a filter with a housing that is at least partially transparent.
Abstract:
A surface cleaning apparatus comprises a dirt inlet, a handle, at least a first cleaning stage comprising a plurality of cyclones in parallel and a plurality of dirt collection chambers that are emptied concurrently wherein the plurality of cyclones and the plurality of dirt collection chambers are removable as a unit from the surface cleaning apparatus, and an air flow motor.
Abstract:
An appliance comprises an electrically operated member; and, a power control system electrically connectable to a power source and the electrically operated member, the power control system reducing the voltage delivered to the electrically operated member to an essentially constant level less than the voltage delivered by the power source when the appliance is actuated. Methods of using the power control system are also provided.
Abstract:
A surface cleaning apparatus (60) comprises a dirty air inlet(64), a clean air outlet (12), an air flow passage extending between the dirty air inlet and the clean air outlet (12), the air flow passage in fluid communication with a motor and fan assembly (15) which is driven by at least one battery (5, 6) positioned in the vacuum cleaner external to the air flow passage, and at least one cooling fan (26, 27) positioned external to the air flow passage positioned to direct airflow at the at least one battery (5, 6).
Abstract:
A method and apparatus is provided which uses a plurality of batteries (38) that are sequentially used to power an appliance (10). While one or more batteries (38) are used to power the appliance, one or more spar batteries (38) are charged for subsequent use. The rate of charge of the batteries (38) is comparable to the rate of discharge of the batteries (38) by the appliance (10) or faster. Thus the appliance (10) may be essentially continuously used by the user removing the discharged battery (38) and inserting a charged battery (38).
Abstract:
An ozone generator has a dielectric element, first and second opposed end cap members and a gas passageway positioned between a high voltage electrode and a ground plane and positioned internal of the dielectric element, and at least one securring member extending between the opposed end caps whereby the securring member holds the end caps in place.
