A method of applying a treatment to a surface of an open body having a volume within an interior of the open body comprises; providing an inner structure (110) shaped to complement the shape of the interior of the open body and to fill a major portion of the volume or a major portion of a width of the interior of the open body; positioning the inner structure (110) within the open body in order to form a treatment fluid inner volume comprising an inner space (150) confronting an inner surface within the interior of the open body; and introducing a treatment fluid into the treatment fluid inner volume to thereby modify the inner surface of the open body by applying the treatment using the treatment fluid. Optionally, the method includes providing a tank (120) shaped to complement and contain the open body; positioning the open body within the tank (120) in order to form a treatment fluid outer volume comprising an outer space confronting the outer surface of the open body; and introducing the treatment fluid into the treatment fluid outer volume to thereby modify the outer surface of the open body by applying the treatment using the treatment fluid.

A simple hand held label degrading device and method employs a molded polymer ring (collar) having a plurality of molded hardened pointed teeth on the internal circumference projecting radially inward for degrading the label of a prescription bottle or the like inserted therein. A longitudinal slot in the collar allows it to be fitted over a bottle such that simple hand squeezing of the collar compresses the collar around the bottle and engages the pointed teeth against the label. Simple hand twisting of the collar around the bottle in a clockwise or counterclockwise rotation cuts through the plastic composite or paper label and shreds the label rendering sensitive information illegible thus protecting personal health information. The bottles can then be thrown away or recycled without fear of medical identity theft.

This application provides an intelligent robot for cleaning and mending a net cage and a method of using the intelligent robot, including: a control system, a main body, an attraction module, a motion module, a cleaning module and a mending module. The main body includes a streamlined pressure casing, and a drive mechanism and a water ballast tank which are located in the pressure casing. The attraction module includes electromagnets which are symmetrically provided at a bottom of the pressure casing. The motion module includes first and second motion mechanisms which are symmetrically provided at opposite sides of the pressure casing. A traveling path of the first motion mechanisms is perpendicular to a traveling path of the second motion mechanisms. The intelligent robot achieves cleaning and mending for both sides of the net cage, and is simple to operate, safe, high-efficient, economical and convenient.

A tank, such as a fermentation tank, includes a scraper blade assembly slideably coupled to a bottom surface of the tank. The scraper blade assembly includes a blade arranged to displace solids deposited on the bottom surface of the tank out through an aperture arranged flush with the bottom surface of the tank.

An apparatus includes a casing configured to be detachably mounted on a workpiece. The casing includes a first opening configured to expose a portion of the workpiece; a first support member coupled to the casing and constructed to move along a first axis through the casing and rotate around the first axis; a second support member coupled to the first support member and constructed to move along a second axis perpendicular to the first axis; an arm pivotally coupled to the second support member and constructed to rotate around a third axis perpendicular to the first axis and the second axis; and a cleaning head attached to the arm and constructed to rotate around a longitudinal axis of the arm. The casing includes a first plate and a second plate opposite to the first plate, wherein the cleaning head is configured to extend outside the casing through the first opening.

A scrubbing apparatus that is adapted to clean both a mixing paddle and an inner surface of a mixing vessel having an inner diameter and a depth. The scrubbing apparatus has a central structure. Outward facing wipes are attached to the central structure, where distal ends of the outward facing wipes form a perimeter having a diameter that is no less than the inner diameter of the mixing vessel. Inward facing wipes are attached to the central structure, where distal ends of the inward facing wipes are disposed proximate one another.
