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 process of separating water from ambient air involves a liquid desiccant to first withdraw water from air and treatment of the liquid desiccant to produce water and regenerated desiccant. Water lean air is released to the atmosphere. Heat generated in the process is recycled. The drying capacity, or volume of water produced, of the system for a given energy input is favored over the production of dried air.

Abstract: A method for treating a liquid such as water with a gas such as ozone where the liquid to be treated is introduced into a treatment vessel, gas is introduced into the treatment vessel to treat the liquid and the liquid is treated. The treatment vessel is then pressurized and the pressure in the treatment vessel is used to dispense the treated liquid from the treatment vessel through a filter.

Abstract: In a braking system for a vehicle including a pressure chamber, a pushrod extending longitudinally outwards from the pressure chamber and movable when correctly adjusted between first and second positions, a brake assembly for braking the vehicle and a pivot member for pivotally mounting a portion of the brake assembly to a portion of the pushrod, the improvement comprising:(a) an indicator adapted to be mounted for longitudinal movement with the pushrod;(b) a reference member for marking one of the first and the second position, the reference member mounted in an opposed position to the indicator; and,(c) the pivot member comprising a clevis pin having an outer surface, first and second ends and at least one lubrication channel for providing grease to the outer surface adjacent at least one the portion of the brake assembly pivotally mounted on the clevis pin and the portion of the pushrod pivotally mounted on the clevis pin.

Abstract: An apparatus comprising a longitudinally extending housing having a fluid inlet port; at leat one plurality of spaced apart members rotatably mounted in the housing to transmit motive force between fluid introduced through the fluid inlet port and the members, the spaced apart members having an upstream end and a downstream end; and, a fluid outlet port extending longitudinally along the housing and having a first end positioned towards the upstream end of the spaced apart members and a second end positioned towards the downstream end of the spaced apart members, the second end of the fluid outlet port radially displaced along the housing from the first end.

Abstract: A wood member comprises first and second opposed members made of wood and secured together. Each of the first and second members has spaced sides and a surface extending between the sides. The surfaces include a first portion contoured to define a contact surface which extends in more than one plane, the first portions defining a space therebetween for receiving an adhesive for securing the first and second members together; a second portion contoured to restrict the flow of the adhesive to a position outward from the sides when the first and second members are brought into engagement; and, opposed engagement members configured to lockingly engage without substantial deformation of the engagement members and secure the first and second members together as the adhesive dries.

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 method of assisting a person to withdraw from cigarette induced nicotine dependency, comprising introducing a predetermined dose of a non-pressurized, particulate medicament comprising at least one nicotine formulation suitable for absorption into the bloodstream of the person through the alveoli and small airways of the person's lungs into a breath activated inhaler for use by said person as a cigarette substitute. A breath activated inhaler which may be used in accordance with this method is also disclosed.

Abstract: A vacuum cleaner handle is provided which offers improved ergonomic characteristics by providing a grip portion which is rotatably mounted and may be offset from the center line axis of the cleaner head.

Abstract: A vacuum cleaner head having a dirty air inlet has an associated restricting member which is operable to reduce the size of the dirty air inlet thereby increasing the velocity of the air entering the air flow path.

Abstract: An apparatus for producing ozone from oxygen comprises a high voltage electrode connectable to a current source; a ground electrode spaced from the high voltage electrode and having an upstream end and a downstream end; a dielectric element positioned between the high voltage electrode and the ground electrode; a path for air flow positioned between the dielectric element and the ground electrode; and, a current collector positioned downstream of the high voltage electrode and comprising an extension of the ground electrode.

Abstract: A method for a person to wash their hands using a hand washing apparatus comprising a hand washing bowl having an interior and a cover which are reconfigurable between a hand washing position in which the person can wash their hands and an inactive position, a controller for reconfigurating the bowl between the hand washing position and the inactive position; and, a dispenser for dispensing water and a cleaner over the person's hands, the method comprising the steps of actuating the controller to rotate the bowl and the cover about an axis to the hand washing position; dispensing water and soap over the person's hands; and, dispensing water to rinse the person's hands.
