摘要： Techniques for depowdering in additive fabrication are provided. According to some aspects, techniques are provided that separate powder from additively fabricated parts through liquid immersion of the parts. Motion of the liquid, such as liquid currents, may dislodge or otherwise move powder away from additively fabricated parts to which it is adhered or otherwise proximate to. The liquid may also provide a vehicle to carry away powder from the additively fabricated parts. Removed powder may be filtered or otherwise separated from the liquid to allow recirculation of the liquid to the parts and/or to enable re-use of the powder in subsequent additive fabrication processes. Techniques for depowdering through liquid immersion may be automated, thereby mitigating challenges associated with manual depowdering operations.

摘要： 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.

摘要： 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.

摘要： An apparatus for cleaning game, fruit, vegetables, fish, or crustacea in a container has a pipe and a connector connected to the pipe adjacent one end of the pipe. The pipe has a plurality of apertures formed in spaced relation to each other along a length of the pipe. The pipe is adapted to extend generally vertical within the container. The plurality of apertures are adapted to direct a flow of water in a generally cyclonic path in the container. The connector is adapted to introduce water into and through the pipe from a water hose or a conduit. A fastener is affixed to the pipe or the connector so as to removably affix the pipe to the a container. A spacer is affixed to the pipe so as to position the pipe a distance away from a wall of the container.
