Abstract: The present invention is a device and system for cleaning and washing containers, including open containers such as carts or tanks, and closed containers such as casks and drums, for virtually any industry. The device is used in combination with any hot water pressure washer. The container washing device and system according to the invention is able to wash a container in under one minute using less than 3.2 gallons of water. The containers are loaded in a horizontal position onto a platform or portable table while maintaining a low profile. A wash head driver by a power head translates in and out of the cart to bring a turbo nozzle in close proximity with all interior cart surfaces. Advantageously a gear train in the wash head has a tooth ratio that produces a non-repeating path for the wash head which rotates the turbo nozzle in two different planes, while reciprocating linearly in and out of the container.

Abstract: A heat exchange system for recycling waste heat, such as that leaving a building stack or flue, to supply heat where needed, such as to incoming fresh air or to tempered stored water of the building water storage system, wherein the building has a source of heat at a constant temperature (such as a furnace, a cooking facility, or a washing facility), from which waste heat is involved in the materials to be conveyed therefrom for discharge from the building, in which a closed circuit heat generated refrigerant flow type refrigeration system is established including a heat recovery coil in heat exchange relation to the waste heat, a heat discharge coil in heat transfer relation to the fluid to be heated at a level above that of the heat recovery coil, and a refrigerant receiver at a level adjacent the level of the heat recovery coil, with the system being charged with a halogenated hydrocarbon type refrigerant to bring the liquid level of the charge within the receiver above the level of the heat recovery coil

Abstract: A heat exchange system for recycling waste heat leaving a building stack to supply heat to incoming fresh air or temper stored water of the building water storage system, wherein the building has a source of heat at constant temperature, such as a cooking facility, from which air conveying waste heat is drawn and impelled through a stack in which a closed circuit heat generated refrigerant flow type refrigeration system is established including a heat recovery coil in the stack, heat discharge coils in heat transfer relation to the incoming fresh air and the stored water, liquid refrigerant traps that permit free flow therethrough of the refrigerant adjacent the heat discharge coils adjacent their discharge ends, and thermostatically controlled valves for alternately disconnecting the heat discharge coils from the heat recovery coil in accordance with a predetermined ambient air temperature exteriorally of the building.

Abstract: An environmental hood and duct structure for griddle and the like cooking equipment used in restaurant and similar facilities, for degreasing the air ambient to the cooking equipment, including a hood arrangement defining a water spray chamber having an air intake opening overlying the cooking surface of the cooking equipment involved, in which air intake opening is mounted an upwardly inclined grilling formed to define a plurality of individual grille openings shaped to provide a venturi effect on the air passing therethrough. The air is drawn across the cooking surface and into and through the grilling at a rate on the order of 1,000-3,000 cubic feet per minute, with the venturi affected air, on passing into the spraying chamber, being subjected to a cool water spray for wet scrubbing of the grease from the air. The scrubbed air is discharged to the atmosphere.
