A cleaning system for cleaning a circular panel or any other circular surface is provided. The system has a base mechanically fastened to the circular panel. An axis stub pivotally connected to the base and attached to a pivot member provides rotation for a blade set. The blade set includes a first blade and a second blade configured to rotate independently about the pivot member in either a clockwise or a counter clockwise direction, wherein the second blade is configured to sit above the first bade, each blade having at least one row of sprinkler holes positioned on each side of the blade running lengthwise. The at least one row of sprinkler holes are configured to eject a fluid to either clean, cool, or thaw the circular panel. The first blade includes a roller having cleaning implements configured to clean the circular panel as the first blade rotates about the pivot member.

A cleaning system for an additively manufactured component includes a tank storing a cleaning fluid. A fluid circuit is operably coupled with the tank. A pump is coupled with the fluid circuit. A manifold is configured to receive fluid from the fluid circuit through the pump. At least one of a coupler defined by the manifold or a hose is coupled with the manifold. The at least one of the coupler defined by the manifold or the hose is further configured to couple with said additively manufactured component.

A wafer processing method of the present invention includes mounting a wafer part on a chuck table, loading a ring cover unit on the chuck table to restrain the wafer part to the chuck table, spraying, by a spray suction arm module, a processing solution onto the wafer part and suctioning, by the spray suction arm module, foreign materials from the processing solution, unloading the ring cover unit from the chuck table, and spraying, by a spray arm module, a cleaning solution onto the wafer part to clean the wafer part.

A head-mounted display system includes a head mounted display unit with a display and a positioning and stabilising structure configured to hold the head-mounted display unit in an operable position on the user's head in use. The positioning and stabilizing structure includes headgear with at least one strap configured to contact the user's head, in use. The head mounted display unit and at least a portion of the positioning and stabilizing structure are formed from a one piece construction of textile material.

A hydroblaster includes a carriage. A plurality of bearings is rotatably mounted to the carriage at a bottom portion of the carriage. A plurality of legs is mounted to the carriage at the bottom portion of the carriage. The plurality of legs extend downwardly from the bottom portion of the carriage past the plurality of bearings. A fluid conduit is disposed on the carriage at a top portion of the carriage. A first motor is mounted to the carriage at the top portion of the carriage. The first motor is coupled to the fluid conduit such that the first motor is operable to rotate the fluid conduit. A second motor is mounted to the carriage at the top portion of the carriage. The second motor is coupled to a gear positioned at the bottom portion of the carriage such that the second motor is operable to rotate the gear.

A method comprises, based on a position of a medical instrument within a patient anatomy, determining, by a control system, whether an obstruction is on a surface of a lens of the medical instrument. The method further comprises, based on a determination that the obstruction is on the surface of the lens, instructing, by the control system, a valve control mechanism to open a valve to release a flow of pressurized fluid through a nozzle of the medical instrument and over the surface of the lens. The valve is configured to control provision of the pressurized fluid.

A mattress cleaning system receives a mattress in a tank of wash liquid so that the mattress is fully submerged. A pressure applicator, for example a mechanical structure or a jetted flow of wash fluid, applies a cyclical compressive force to the sleeping surface of the mattress while the mattress is fully submerged so as to cause flushing of the wash liquid outwardly of the mattress through at least the sleeping surface of the mattress. When using a barrier to isolate one of the surfaces of the mattress on a first side of the barrier from remaining surfaces of the mattress on a second side of the barrier, use of a blower to create an air pressure differential between opposing sides of the barrier causes migration of the wash liquid through the mattress from the isolated surface of the mattress to the remaining surfaces for drying the mattress.

The present invention relates to an apparatus for cleaning press rolls for electrodes, comprising two or more cleaning units provided with cleaning members having grains. According to the present invention, the apparatus for cleaning press rolls for electrodes comprises a plurality of, i.e., two or more, cleaning units, wherein the cleaning units respectively comprise cleaning members having grains with different directions, thus allowing a residual cleaning solution and contaminants to be effectively removed. In addition, when press rolls are cleaned using the apparatus for cleaning press rolls according to the present invention, an aqueous cleaning solution and an alcoholic cleaning solution, which have different properties, can be used together, and after cleaning, the cleaning solutions do not remain on the press rolls, and thus subsequently, secondary contamination of electrodes is prevented, and accordingly, when electrodes are manufactured, the occurrence of defects in the electrodes can be reduced.
