Abstract: A washing machine including a tub having a helical flow path defined by a channel and a sump located at a lower end of the channel with a dam therein is described. In an exemplary embodiment, a water outlet is located in the sump, and the dam is positioned in the sump upstream from the outlet. The dam, in the exemplary embodiment, is substantially perpendicular to flow path and extends from a tub sidewall to at least beyond the outer perimeter of the water outlet. The dam has a sufficient height to prevent debris heavier than water from flowing from the channel to the outlet during a non-spin portion of a wash cycle, yet is low enough so that when the spin cycle is initiated, the debris will flow over the dam to the outlet.

Abstract: A method of controlling a dispenser duct door, including positioning an upper side of the door, in a closed position, in a door-opening direction, and rotating a bottom end of the door to a partially open position vertically under the upper side of the door in response to an opening signal. The bottom end of the door is rotated further in the door-opening direction in response to ice hitting a rear of the door and is returned to the partially open position. After a predetermined delay, the bottom end of the door is returned to the closed position.

Abstract: The appliance comprises a container for receiving the soiled articles, a circulation pump for distributing a hot liquid to the container, a drain positioned in the container and connected to the pump for emptying the liquid from the container upon completion of a cycle and a hydroclone connected to the drain and the pump, for removing soil from the liquid such that about ninety percent (90%) of the liquid distributed to the container during one cycle can be utilized during at least one subsequent cycle.

Abstract: Apparatus including water traps for containing pump gurgling noise within a washing machine are described. In one embodiment, tub outlet openings are formed in the washing machine tub bottom wall, and the apparatus includes an inlet in flow communication, and integral, with the tub water outlet. The pump inlet hose is coupled to the apparatus outlet so that the outlet is in flow communication with the water pump. The water trap is located between the apparatus inlet and outlet, and the water trap includes a u-shaped channel, a baffle extending from a lower surface of the tub bottom wall, and a standpipe. The u-shaped channel includes a water reservoir portion at an elevation below an end of the standpipe. In operation, water from the tub is discharged from the tub through the tub water outlets and into the apparatus.

Abstract: A method for extinguishing flammable and combustible liquid tank fires using foam comprising empirically determining a footprint for a plurality of nozzles and configuring and aiming nozzles with respect to a tank such that predicted footprint and foam run would cover a tank surface with foam. Also method and apparatus for extinguishing tank fires including crude and high vapor pressure flammable liquid tank fires that includes applying foam in a footprint to cover liquid surface and cooling portions of the tank wall.

Abstract: A plastic molded, upper dishwasher rack and support assemblies are described. In one embodiment, the upper rack is supported by first and second upper rack support assemblies, and each support assembly includes an elongate slide member and first and second roller assemblies secured to respective sidewalls of the tub. Each elongate slide member includes a channel, and upper and lower flanges. The rollers are located within the channels so that the slide member is movable relative to first and second rollers. Front and rear caps are secured to a front end and a back end, respectively, of each slide member. The flanges and caps facilitate retaining, or trapping, the rollers within the channels. In addition, the front caps have stop members extending inwardly towards the upper rack and cooperate with the upper rack to limit the extent to which the upper rack can be withdrawn from tub.

Abstract: A fire fighting nozzle wherein an additive fluid, such as foam concentrate or other liquid or gas, is supplied to a fluid passageway located peripherally along portions of a nozzle barrel wall and is discharged proximate the barrel discharge end, and preferably including educting the additive fluid into the nozzle using flow of the liquid through the barrel.

Abstract: Mechanical foam fire fighting equipment and method wherein an inert gas is delivered to a foaming chamber of a mechanical foam making assembly, the foaming chamber also receiving a liquid and foam concentrate, the inert gas in some embodiments being supplied by the exhaust of an engine.

Abstract: The present invention provides a method for extinguishing ship container fires by introducing an inert gas into the container to drive combustible gas such as air out of the container. The method includes the steps of drilling at least one hole in a wall of a ship container, attaching a toggle bolt to one end of a wall fitting, sliding a gasket over the other end of the wall fitting, inserting the wall fitting into the drilled hole such that the toggle bolt expands against the inside wall of the container, sealingly attaching the wall fitting around the drilled hole, attaching tubing to the fitting to establish fluid communication between the tubing and the inside of the container, coupling a portion of the tubing to a source of inert gas, and controlling the communication of the inert gas through the tubing and fitting to drive combustible gas out of the container.
