    Abstract: A filtration system for a dishwasher, and an associated apparatus and method, are provided, comprising a macerator chamber adapted to house a macerator device. The macerator chamber is configured to receive washing fluid for the macerator device to comminute contaminants within the washing fluid. A drain chamber is in fluid communication with the macerator chamber and is configured to receive the washing fluid and comminuted contaminants therefrom via a fluid port therebetween. The drain chamber has a vented member associated therewith, which defines at least one first vent providing fluid communication between the drain chamber and the washing fluid circulation system. The vented member is spaced apart from the fluid port, and is configured to strain the comminuted contaminants from the washing fluid so as to retain the comminuted contaminants within the drain chamber while allowing the washing fluid to pass therethrough to the washing fluid circulation system.

  • Patent number: 7806951
    Abstract: The present invention is a mobile air contaminant control system that includes a filter assembly enclosed by a mobile outer chamber. The filter assembly is tapered to create a large volume air way downstream from the filter assembly that enables more even air flow and filter loading. One or more exhaust fans pull the air through the filter assembly and exhaust it to the exterior of the chamber. The system is functionally attached to an exterior structure having at least one air intake and housing a work piece. As airborne contaminants are generated from the work piece(s), the control system exhausts them from the exterior structure through the filter assembly and into the external environment.

  • Patent number: 7754020
    Abstract: A recovery system recycles the washwater used to clean excess binder and debris from the production components, including a forming hoodwall constructed of non-corrosive materials, for manufacturing fiberglass insulation. A separate closed-loop recovery system is provided for the forming hoodwall in which the binder-containing washwater is screened and then recycled back to the forming hoodwall without further chemical treatment to change the pH level. A binder reclamation system is coupled to the hoodwall washwater recovery system to divert the low pH washwater when the supply of binder needs replenished at the forming hoodwall. The binder reclamation system introduces an acid solution to the cleaned washwater to lower the pH from about 2.5 to about 3.5. The other production components share a bulk washwater recovery system in which a base solution is introduced to raise the pH to approximately 8 or above to reduce corrosion in the other production components.

  • Patent number: 7497222
    Abstract: A dishwashing machine including a comminution device and a method for comminuting residue in the dishwasher. The comminution device at minimal manufacturing costs, makes it possible to easily comminute the coarse contaminants or residue accumulating during the rinse cycle in the dishwashing machine, flush it out of the dishwasher and at the same time reduce the danger of clogging the sieve(s) placed in the dishwasher. The comminution device preferably is actuated by the lye pump of the dishwashing machine. In this manner the comminution device is actuated easily and efficiently, which both enables cost-effective manufacture of the dishwashing machine, and improves its operating safety and ease of maintenance. In the process the rinse residue can first collect during the rinse cycle in uncomminuted form on the floor of the rinsing container and only then be comminuted when the washing liquid is pumped out and flushed out of the dishwashing machine.

  • Patent number: 7472712
    Abstract: An automatic dishwasher having a wash chamber is provided with a filter for filtering wash liquid circulated in the wash chamber. The filter includes a filter chamber outside the wash chamber. An inlet to and outlet from the filter chamber in a wall of the wash chamber allows wash liquid circulating in the wash chamber to enter the filter chamber and to flow out of the filter chamber through a filter element back into the wash chamber for filtering particulate material from wash liquid circulating in the wash chamber. A drain outlet at the bottom of the filter chamber allows wash liquid and material filtered by the filter to flow to the household drain. Sensors can be provided to detect a clogged or partially clogged filter and initiate a purge cycle to remove wash liquid and material filtered by the filter to the household drain.

  • Patent number: 7472711
    Abstract: A dishwasher includes a pump assembly which functions to chop all fluid entrained soil prior to directing fluid to upper and lower wash arms. A flow conduit leading to the upper wash arm is provided with a sampling port which directs a percentage of the fluid flow into a filter chamber having one or more fine mesh filter screens that open into the dishwasher tub basin. The filter chamber is exposed to a collection chamber that leads to a drain. In the event the filter chamber becomes clogged, a pressure relief valve opens a pressure regulation port to permit washing fluid in the filter chamber to enter the tub basin. In one embodiment, the pressure relief valve is constituted by a check ball which is displaced by a pressure build up in the filter chamber. In another embodiment, the pressure relief valve is constituted by a flapper valve.

  • Patent number: 7467636
    Abstract: A dishwasher includes a pump assembly having a multi-stage filtering arrangement which functions to trap soil particles contained in a washing fluid to reduce the number of fresh water fills required to perform a washing operation. All of the washing fluid is initially directed over a filter plate. A first portion of the washing fluid passes the filter plate into a pumping chamber, while a second, soil laden portion, enters a first filter chamber. The second portion is then directed through a medium filter into the intake chamber. The filtered washing fluid is pumped through a conduit to wash arms that spray the washing fluid onto kitchenware. The conduit includes a sampling port which directs a portion of the washing fluid to a second filtering compartment having a fine mesh screen. At the end of the washing operation, the washing water, along with the soil is expelled from the dishwasher.

  • Publication number: 20080264443
    Abstract: The present invention pertains to a system for processing semiconductor wafers. The processing may involve the removal of material from the wafers or deposition of material on the wafers. Various aspects of the invention include specialized pressurization, process vessel, recirculation, chemical addition, depressurization, and recapture-recycle subsystems. A solvent delivery mechanism can convert a liquid-state sub-critical solution to a supercritical processing solution and introduce it into a process vessel that contains a batch of wafers. The wafers may be rotated within the supercritical processing solution. The supercritical processing solution is preferably recirculated through the process vessel by a recirculation system. When chemical additives are added to a supercritical solvent, the momentum of the chemical additives are preferably matched to the momentum of the supercritical solvent. Additives may be added at a higher initial flow rate, then ramped down a lower flow rate, e.g.
