Abstract:
A method of generating ozone containing fluid comprising: drawing atmospheric air into an air compartment, generating ozone within the air compartment from air in the air compartment by conversion within the compartment of oxygen in the air within the compartment into ozone to form ozonated air, discharging the ozonated air from the air compartment, mixing the ozonated discharged air with a flowable fluid to form an ozonated fluid-air mixture, and passing the ozonated fluid-air mixture out a discharge outlet. Preferrably the method is carried out in a dispenser utilizing a piston pump to draw air through a corona discharge ozone generator and to draw liquid from a liquid reservoir and simultaneously pass both the ozonated air and liquid through a foam generator to generate foam.
Abstract:
A piston pump dispenser having a reciprocating piston pump arrangement in which in a dispensing stroke in which fluid is pressurized in a chamber (18) to dispense fluid, a piston slide member (120) is urged into a sealing disc of a piston sleeve member (100) to increase the extent to which the sealing disc provides a seal with a wall of the chamber against fluid leaking out past the seal disc.
Abstract:
A removable and replaceable keying component which is required for operation of a mechanism and which component includes a waveguide having a photochromic portion. A method of controlling operation of a mechanism, preferably a dispenser (10), having a removable component (12) comprising the steps of measuring electromagnetic radiation passing through a waveguide carrying at least in part on the removable component (12) and permitting operation of the mechanism only when the measured electromagnetic radiation corresponds with one or more pre-selected parameters. Preferably, the method involves directing emitted electromagnetic radiation with pre-selected input parameters selected from a plurality of input parameters.
Abstract:
An improved arrangement for removably coupling a replaceable cartridge to a housing of a dispenser with the cartridge including a resilient member which prevents radial movement relative a catch member of the housing from a coupled orientation unless the resilient member is deflected from an unbiased inherent configuration.
Abstract:
The present invention provides a piston pump for liquid in which a sump is defined in a chamber into which sump liquid in the chamber flows due to gravity. A passageway leads from an outlet of the sump out of the chamber to a dispensing outlet. The dispensing outlet is at a height below the height of the sump outlet and fluid to exit the sump flows from the sump outlet upwardly in a first portion of the passageway to a height above the sump outlet then downwardly to the dispensing outlet. The chamber and its sump is defined between a piston chamber-forming member defining the chamber to be downwardly opening and a piston forming element axially slidable in the chamber.
Abstract:
A universal wall plate which can be secured to a wall and to which a variety of dispensers can readily be secured and removed with minimal effort, without the need to remove the wall panel and without causing damage to the wall.

Abstract:
A dispensing system (10) comprising: an activation unit (48), and a reservoir assembly (12) including a reservoir containing material to be dispensed, the reservoir assembly (12) removably coupled to the activation unit (48) for replacement by a similar reservoir assembly (12), an electromagnetic radiation waveguide (64; 184; 200) having an inlet and an outlet and providing a path (64; 264) for transmission of electromagnetic radiation from the inlet to the outlet, the waveguide comprising a frangible portion the electromagnetic radiation sensor (56; 72; 256; 356) carried by the activation unit (48) sensing electromagnetic radiation from the waveguide (64; 184; 200) via an outlet, at least part of the waveguide (64; 184; 200) carried by the reservoir assembly and removable therewith, and a control mechanism to permit operation of the dispenser system (10) only when the electromagnetic radiation sensed by the sensor appropriately correlates to a pre-selected electromagnetic radiation profile, wherein removal of the reservoir assembly (12) from the activation unit (48) breaks the frangible portion.
