Abstract: A cleaning apparatus includes a liquid delivery system in fluid communication with a supply tank. A suction source is configured to generate a vacuum effect along an airflow path. A recovery tank assembly includes a sorting channel extending between a fluid inlet and a fluid outlet. A proximal end of the sorting channel is larger than a distal end thereof for controlling an airflow speed through the sorting channel. A separator at least partially defines the sorting channel and includes a fluid permeable portion. Liquids and solid materials are configured to be directed through the sorting channel by the suction source with the liquids being directed through the fluid permeable portion to be collected in a liquids collection area below the fluid permeable portion the solid materials being collected in a solids collection area disposed along the airflow path between the fluid inlet and the fluid outlet.

Abstract: A cleaning apparatus includes a housing, a suction assembly, and a fluid delivery system. A wand is coupled to the housing via an accessory hose. The wand includes a trigger and a fluid outlet. Actuation of the trigger provides fluid communication between the fluid delivery system and the fluid outlet for releasing a liquid. A vacuum tool is coupled to the wand. The vacuum tool includes a support body that defines an open end for receiving the wand and includes a guard that extends beyond the open end to extend over the trigger to prevent the actuation of the trigger. An intermediate recovery tank is coupled to the support body and defines an inlet in fluid communication with the suction assembly. A separator is disposed within the intermediate recovery tank to retain the debris within the interior and allow airflow to be directed through the separator to the accessory hose.

Abstract: An accessory tool usable with an extraction cleaner having fluid delivery and recovery systems includes a conduit body, spray nozzle, and first and second valves. The conduit body contains a fluid delivery pathway and an airflow pathway. The fluid delivery pathway connects to the fluid delivery system at a hose end of a wand. The airflow pathway connects to the fluid recovery system at the same hose end. The spray nozzle is in fluid communication with the fluid delivery pathway. The second valve is operable for selectively directing a liquid stream, i.e., cleaning fluid provided by the extraction cleaner, to the spray nozzle when the hose end is attached to the extraction cleaner via an accessory hose. The first valve is operable for selectively diverting the liquid stream into the airflow pathway to clean the hose.

Responsive to a player input a player input rate measurement is adjusted based on a rate of player inputs over time. A velocity of a first one of the moving elements is adjusted based on the player rate input measurement and adjusting a conclusion of the animated game effect based at least in part on the movement of the adjusted moving element.

Abstract: An air purifier and a passive humidity module for inside air. The air purifier includes a housing and an air purifier air outlet. The passive humidity module is disposed at least partially on the air purifier air outlet. The passive humidity module includes a housing assembly defining an air inlet and an air outlet, a water tank supported by the housing assembly, a wick filter reservoir fluidly coupled to the water tank, at least one gutter fluidly coupled to the water tank, and a wick filter disposed in the wick filter reservoir and supported by the housing assembly. The air inlet is at least partially aligned with the air purifier air outlet. The passive humidity module includes an airflow path flowing between the water tank and the wick filter, and fluidly connecting the air inlet and the air outlet.

Abstract: An ink composition contains a semi-drying solvent; a pigment; an alkyd resin; and an amine-based polymeric dispersant. The composition contains 5 wt % or more of the alkyd resin, based on the total weight of the composition, and 5 wt % or more of the amine-based polymeric dispersant, based on the total weight of the composition.

Abstract: A handheld extraction cleaner system includes a wet cleaning head including a wet suction nozzle, a dry cleaning head including a dry suction nozzle. A handheld base includes a modular receiver configured to interchangeably couple to the wet cleaning head and the dry cleaning head. A suction source is configured to generate a suction air stream through the wet suction nozzle when the wet cleaning head is coupled to the modular receiver and through the dry suction nozzle when the dry cleaning head is coupled to the modular receiver. A fluid delivery system includes a fluid distributor configured to dispense a cleaning solution on a surface to be cleaned, where at least one of the handheld base and the dry cleaning head is configured to at least partially prevent the fluid delivery system from dispensing the cleaning solution when the dry cleaning head is coupled to the modular receiver.

Abstract: A player loyalty kiosk, system, method, and program product provide a loyalty game. A gaming interface of a loyalty game includes a matrix of symbol locations with a number of prize symbols, multiple expanding arrow symbols, and a moving highlight indicator. After a start input, a “stop” button is made active for stopping the moving highlight indicator. Responsive to a stop button input, the moving highlight indicator slows and then stops at a selected symbol on the matrix. If it stops on a prize symbol, a first type of game result provides an associated prize for the selected symbol. If it stops on an expanding arrow symbol, a second type of game result highlights an entire row or column of the matrix and provides prizes associated with each symbol location of the row or column.

Abstract: The present disclosure provides engineered polypeptides having imine reductase activity, polynucleotides encoding the engineered imine reductases, host cells capable of expressing the engineered imine reductases, and methods of using these engineered polypeptides with a range of ketone and amine substrate compounds to prepare secondary and tertiary amine product compounds.
