Abstract: A method is disclosed, which comprises estimating a first value of a parameter of a component, prior to a use of the component in a reactor. In an example, the parameter of the component is to change during the use of the component in the reactor. The component may be treated, subsequent to the use of the component in the reactor. A second value of the parameter of the component may be estimated, subsequent to treating the component. The second value may be compared with the first value, where a reuse of the component in the reactor is to occur in response to the second value being within a threshold range of the first value.

Abstract: A vacuum appliance capable of picking up both wet and dry material is described, wherein the vacuum appliance includes an impeller configured to induce liquid into the vacuum appliance, a motor configured to turn the impeller, a restrictor assembly to prevent the liquid from being ingested into the motor, and a bypass vent assembly configured to allow sufficient air to reach the motor in order to keep the motor cool while the restrictor is preventing the liquid from being ingested into the motor. The vacuum appliance also includes a drum configured to retain the liquid and an impeller intake between the impeller and the drum. The restrictor may comprise a float configured to rise with a level of the liquid in the drum and prevent the liquid from entering the impeller intake. The bypass vent assembly may be configured to allow airflow to bypass the restrictor and/or the drum.

Abstract: Vacuum cleaner filters, in particular replaceable vacuum cleaner filters suitable for both dry and wet/dry type vacuum cleaners are disclosed, as well as systems incorporating the use of such filters and methods for their use. The filters include a plurality of adjacently positioned pleats arranged in a closed circumferential, cylindrically-shaped path, a top end cap having a central orifice capable of constricting a post on a vacuum filter cage, and optionally a molded end ring oppositely-spaced from the top end cap for engagement with the motor housing of a vacuum cleaner.

Abstract: A backflush filter cleaning system for use with a vacuum cleaner employing an internal filter may include a filter cage having a first end, a second end and a peripheral opening, a backflush valve coupled to the first end, an intake plenum coupled to the second end, the plenum having an air outlet, an inlet valve coupled between the peripheral opening and the air outlet, and a cleaning actuator coupled to at least one of the valves. The system can be adapted to clean a filter coupled to a vacuum cleaner where the system can include a means for establishing a first airflow path from inside the collector through the filter, to the vacuum source, a means for flowing air along the first airflow path, and a means for establishing a second airflow path from an atmosphere surrounding the vacuum cleaner through the backflush valve, through the filter, and into the collector to clean the filter.

Abstract: The present disclosure provides a method, apparatus, and system to switch between direct current (DC) and alternating current (AC) power sources for appliances with a third position to allow on-board recharging of the DC power source. The method involves locking out a power source when the other power source is powering the appliance and locking out both power sources from operating the appliance when the appliance is being recharged. The DC power source can remain coupled to the appliance during operation and during recharging without necessitating removal for remote recharging by the use of a unique switch.
