  • Patent number: 11857133
    Abstract: A dishwashing machine is used for pre-rinse operation of soiled dishes. A cavity is configured and arranged to contain the soiled dishes. A nozzle is proximate the cavity and is in fluid communication with the cavity. An accumulator pan accumulates wash and rinse water including cleaning chemicals used in a previous cycle of the dishwashing machine. A fluid passageway interconnects the nozzle and the accumulator pan. A pump directs the accumulated wash and rinse water from the accumulator pan to the nozzle via the fluid passageway for pre-rinse operation of the soiled dishes in the cavity, and the nozzle directs the accumulated wash and rinse water into the cavity with the soiled dishes to assist in removing soil from the soiled dishes prior to a wash cycle of the dishwashing machine. The wash cycle utilizes fresh wash water.

  • Patent number: 9434400
    Abstract: A mobile cleaning system (10) that enables touch-free, daily cleaning and disinfecting to areas or locations within an establishment is provided. The system includes generally a push cart (12) having front (18) and rear (20) sections spaced between vertically upstanding side sections (22A-B). One or more sections of the cart (12) include a modulated space configurable with one or more cleaning and/or disinfecting modules for performing and supporting a cleaning and/or disinfecting operation. A tool drip tray (30) extends outward from at least one of the sections beneath a tool storage location (32A-B) for preventing liquid or debris from dropping onto a surface beneath the cart (12) while stationary or in transit.

  • Patent number: 8313650
    Abstract: A system for regulating a reverse osmosis system to obtain zero wastewater. A reverse osmosis apparatus filters water from the fresh water supply into a concentrate rinse stream and a permeate rinse stream. A concentrate storage tank and a permeate storage tank are downstream of the reverse osmosis apparatus and receive the concentrate rinse stream and the permeate rinse stream, respectively. A concentrate solenoid valve and a permeate solenoid valve control the flow of the concentrate rinse stream and the permeate rinse stream from their respective storage tank. An institutional dishmachine receives the concentrate rinse stream and the permeate rinse stream during a rinse cycle of the institutional dishmachine. A control system is operatively connected to the concentrate solenoid valve and the permeate solenoid valve and control flow of the rinse streams into the institutional dishmachine.

  • Patent number: 5301494
    Abstract: A recharging system for a battery operated tool such as a lawn mower. A slidable cover is used which is movable between an open position and a closed position. The slidable cover alternately exposes a receptacle adapted to receive a removable fuse key and an electrical connector adapted to receive an electrical power cord. The receptacle and the electrical connector are longitudinally aligned with the cover so that for the cover to move to the open position and expose the electrical connector, the fuse key must be removed. The receptacle is electrically connected in series with an activation switch, the battery and the electric motor to form a motor circuit. When the fuse key is removed to expose the electrical connector, the motor circuit is broken which prevents the electric motor from being activated whether or not the activation switch is engaged.

  • Patent number: 5261215
    Abstract: A lawn mower is provided having a deck which is supported by a pair of front wheels and a pair of rear wheels above a surface when operated in a horizontal mode. A leg is affixed to a rear portion of the deck and projects outwardly therefrom. A handle assembly is affixed to the deck so as to be movable between an extended operating position and a retracted storage position. The leg cooperates with the pair of rear wheels to provide a stable support for the lawn mower enabling generally vertical storage of the lawn mower relative to the surface once the handle assembly has been moved to the retracted storage position.
