A scraper blade for a frozen dessert machine includes a blade body extending from a first end to a second end. The blade body includes a cutting edge on a first side of the blade body facing a scraping direction. A biasing projection extends from a second side of the blade body in a direction opposite the scraping direction of the cutting edge. A frozen product machine includes a freezing cylinder defining a longitudinal axis and a rotating beater assembly within the freezing cylinder. The rotating beater assembly includes a beater body and a scraper blade as described above. The scraper blade is operatively connected to the beater body. The biasing projection of the scraper blade biases the cutting edge against an inner diameter surface of the freezing cylinder.

A novel, mechanical method and apparatus for scraping desired solids from the interior walls of various vessels, especially spherical glass or metal flasks common to chemical laboratory settings is described. The present invention utilizes spinning, flexible, abrasive tentacles fixed to a vertical shaft. The rotary motion of the vertical shaft is driven by a simple electrical or pneumatic motor. Centrifugal force extends the tentacles, which act as brushes, whereby their abrasive contact with the solids caked to the interior walls effects mechanical scraping. While spinning, the apparatus is moved vertically up and down to effect complete scraping. The present invention, therefore, rapidly removes the majority of dry solid material stuck to the interior of a spherical vessel with a minimum of physical effort. This method provides a significant improvement over the existing standard practice of slow, uncomfortable, manual scraping with spatulas.

An herb grinder with a cleaning attachment comprises a bristle assembly and a grinding assembly which is further comprised of a top grinding component, a bottom grinding component and a collecting compartment. The top grinding component and the bottom grinding component are detachably connected and are configured to be rotated relatively to each other. The bristle assembly and the grinding assembly form an internal space configured to receive the bristle plate, and are both interlocking and magnetically connected to prevent relative rotation between the bristle assembly and the grinding assembly when grinding. The bristle assembly may be detachable to clean the top grinding component and the bottom grinding component. The herb grinder further comprises a housing which is interchangeable with the grinding assembly for convenient portability and storage.

An embodiment provides a method for cleaning a sample cell of a turbidimeter, including: introducing an apparatus comprising a cleaning component into the sample cell, wherein upon introduction of the apparatus into the sample cell a secondary flow path out of the sample cell is opened; engaging a functionality of the apparatus to clean the sample cell; and removing a plurality of particles from the sample cell via the secondary flow path. Other aspects are described and claimed.

A tank cleaning system for cleaning a space. The tank cleaning system can include a trailer having a support base transportable by a vehicle, and an arm movably mounted to the support base for movement relative to the support base. The arm can be operable to extend into the space to perform a cleaning operation inside the space.

A modified tank for use in microgravity environments is provided. The modified tank includes a membrane defining an interior and including an inlet leading to the interior and first and second outlets from the interior. The modified tank further includes first and second filters for the first and second outlets, respectively, and an outlet wiping pair. The outlet wiping pair includes a wiper in the interior and a wiping boss at an exterior of the membrane. The wiping boss is operably coupled to the wiper whereby operation of the wiping boss causes the wiper to wipe at least one of the first and second filters.

A vessel cleaning robotic system includes a robotic cleaner having a cylindrical central unit from which three retractable legs extend. Each leg includes an omni-directional wheel at its distal end, a motor, up to three joints for articulation, and a collar for attachment to the central unit at a proximal end. An arm, also extending from the central unit, is configured to rotate around it, with a cleaning sub-unit at its distal end and a collar at its proximal end. The arm includes a vacuum pipe and a spraying device for cleaning purposes. Integrated within the retractable legs and the arm is a monitoring unit comprising sensors for operational monitoring.

A method includes: providing an apparatus including: a casing having a first plate and a second plate opposite to the first plate; and a robot comprising a first support member, a second support member and a cleaning head; moving the apparatus in its entirety to rest on a workpiece, wherein the casing is moved with the robot until the second plate contacts an upper surface of the workpiece; and causing movement of the first support member, the second support member and the cleaning head to perform a cleaning operation on the workpiece, wherein the casing along with the first plate and the second plate remains stationary on the workpiece during the cleaning operation.

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.
