A device for washing an article in a container of fluid includes a cover having a wash surface, an opposed undersurface, and multiple ducts extending therethrough, where each of the ducts has an internal wall that tapers outwardly as the duct extends away from the wash surface, and a base operatively coupled to the cover, the base having a support surface and an opposed interior surface positioned facing the undersurface of the cover. The device further includes a resilient member operatively coupled between the cover and the base to bias the cover and base apart. Pushing the article against the wash surface presses the cover towards the base and directs a portion of the fluid through the ducts onto the article. Also disclosed are a wash assembly and a washing system including the device.

A method of making a three-dimensional object from a polymerizable resin, the method comprising the steps of: (a) providing a carrier platform on which the three-dimensional object can be formed; (b) producing the three-dimensional object adhered to the carrier platform from the polymerizable resin by stereolithography, the object having residual resin on the surface thereof; (c) immersing the object in a wash liquid with the object remaining adhered to the carrier platform; (d) agitating (i) the object in said wash liquid (e.g., by spinning), (ii) the wash liquid with the object immersed therein (e.g., by sonication of the wash liquid), or (iii) both the object in the wash liquid and the wash liquid with the object immersed therein, to at least partially remove residual resin from the surface of the object; (e) separating the object from the wash liquid, with the object remaining adhered to the carrier platform, the object having residual wash liquid on the surface thereof; (f) agitating the object (e.g., by spinning) to at least partially remove residual wash liquid from the surface thereof; and (g) repeating steps (c) through (f) at least once to remove additional polymerizable resin from the surface thereof, wherein steps (c) through (f) are carried out in the same vessel, said immersing step (c) comprises filling the vessel with the wash liquid, and the separating step (e) comprises draining the wash liquid from the vessel.

A coffee brewing system includes a brew vessel adapted to receive water and ground coffee to produce and store a brewed beverage and to provide for a cleaning system. The brew vessel includes a filter and a magnet stirrer in the lower portion of the brew vessel. The magnet stirrer creates a water vortex for brewing the coffee. The used coffee grounds are allowed to settle on the filter creating a bed of used coffee grounds and the coffee is then filtered through both the bed of used coffee grounds and the filter and collected in a coffee storage container. A cleaning system is used to remove unsightly coffee stains and oil films in the system after a brewing cycle.

A method is disclosed for removing oil from oil covered rocks of reclaimed asphalt that is milled from pavement of a roadway. The oil covered rocks are cleaned so as to be suitable to be mixed with virgin rocks to make new asphalt. The oil covered rocks are submerged within and moved through a water filled bath by an oil scrubber (e.g., a motor driven screw or set of paddles) where the rocks are agitated and rubbed together to cause the oil to separate therefrom. To enhance the oil removal process, steam is sprayed under pressure into the bath from an overhead manifold. To further enhance the oil removal process, the rocks are preheated within an insulated hot box prior to their receipt by the water bath. The cleaned rocks are removed from the bath to be collected, dried and recycled.

An apparatus and method for reprocessing a medical device includes a decontamination basin, a first flush conduit, a second flush conduit, and a manifold. The first and second flush conduits have respective first and second coupling ports configured to fluidly connect to the medical device positioned within the decontamination basin. The manifold is fluidly connected to the first and second flush conduits and configured to distribute the fluid received therein accordingly. The apparatus also includes a first valve, a second valve, and a primary pump configured to discharge the fluid into the manifold at a predetermined supply flow rate. The first and second valve are positioned respectively in the first and second flush conduits for balancing the respective flow rates discharged therefrom at a first predetermined conduit flow rate and a second predetermined conduit flow rate.

A parts-washing method is described. The method comprises: (a) contacting a part with an aqueous liquid cleaning composition in a contact zone at a temperature of less than 45 degrees C., wherein the aqueous liquid cleaning composition comprises at least one alkoxylate surfactant; (b) passing at least part of the aqueous liquid cleaning composition from the contact zone to a separation housing; (c) separating the aqueous liquid cleaning composition in the separation housing to form an upper oily phase, an intermediate aqueous phase and a lower particulate phase; and (d) withdrawing at least a portion of the intermediate aqueous phase for use as the aqueous liquid cleaning composition in the contact zone.

A mop washing bucket has a container with an interior volume defined by a bottom and a wall extending upwardly from the bottom, a fluid inlet affixed adjacent to the bottom of the container, and a fluid outlet formed on the container in a location above the fluid inlet. The fluid inlet is adapted to be connected to a water hose. The fluid inlet extends through the wall of the container so as to have one end in the interior volume of the container and another end exterior of the wall of the container. The fluid outlet is adapted to allow water from the interior volume of the container to flow outwardly of the container.

A method of preparing adipose tissue for transplantation, from lobular fat extracted, for instance, by liposuction, the fat including a fluid component that also includes an oily component, a blood component and/or sterile solutions and of a solid component that includes cell fragments, cells and one or more cell macroagglomerates of heterogeneous size, characterized in that it includes at least one step of forming an emulsion of the fluid component in the sterile washing solution by active and/or passive stirring and discharging the emulsion from the outlet through a density gradient.

An apparatus for electrochemical activation may include an intake for an aqueous salt solution, a flow conduit structured to direct the aqueous salt solution through the apparatus comprising at least two electrodes spaced apart from each other within the flow conduit; a control module electrically coupled to the at least two electrodes, wherein the control module controls application of electricity to the at least two electrodes; and a sensor structured to measure a parameter of the aqueous salt solution and provide feedback to the control module to control an aspect of operation of the apparatus.
