A device for covering a cut gap which can be produced by a machine tool. The device can be connected to a dust suctioning device so that the dust produced while working with the machine tool can be removed from the working area of the machine tool using the dust suctioning tool. A second aspect of the invention relates to a system consisting of at least two proposed devices. Another aspect of the invention relates to a method for suctioning dust from a working region of a machine tool. The device includes sealing caps which can be connected to a dust suctioning device via suction connecting pieces. Furthermore, the sealing caps are used to seal the working area in which the working process of the machine tool is carried out.

A tool for cleaning inside of a water tank utilizing a siphon action is provided in which a scraping tool (S) is pivotably provided at an upstream end of a suction pipe (P), a deposit (b) such as moss caked on a bottom face or a side face within the water tank is scraped off by a scraping blade (62) formed at an extremity of the scraping tool (S), and is removed by sucking up together with dirt (a).

A semiconductor manufacturing equipment cleaning system has a multi-station cleaning and inspection system. Within semiconductor manufacturing equipment cleaning system, a tray cleaning station uses a first rotating brush passing over a first surface of a carrier and possibly semiconductor die, and a second rotating brush passing over a second surface of the carrier and semiconductor die opposite the first surface of the carrier and semiconductor die. Debris and contaminants dislodged from the first surface and second surface of the carrier by the first rotating brush and second rotating brush are removed under vacuum suction. A conveyor transports the carrier through the multi-station cleaning and inspection system. The first rotating brush and second rotating brush move in tandem across the first surface and second surface of the carrier. Air pressure is injected across the first rotating brush and second rotating brush to further remove debris and contaminants.

A system for removing aerosol contaminants from the air in a room is disclosed. The system comprises a vacuum inlet coupled to a vacuum system and operable to draw air from nearby into the vacuum system, filter out aerosol contaminants present in the air, and return the filtered air back into the room. The system includes airways internal to a dental chair, through which air may be drawn and filtered. The system may be used near a patient during a dental or medical procedure to remove aerosol and splatter potentially containing such contaminants as COVID-19 and other infectious diseases.

A portable debris removal system cleans debris and fluids from newly machined parts generally includes an enclosure assembly where a user cleans a machined part with a compressed air gun. The air within the enclosure assembly is evacuated for decontamination through a series of filters with remaining contaminates collected in a waste vessel. Ambient air and air gun expressed compressed air are drawn into the system via the Venturi effect created by a Venturi vent positioned on the bottom of the enclosure assembly.

The invention relates to a method and a system for the processing of an end-of-use pneumatic tyre that is provided with an inner lining (SAL) layer manufactured with a sealing agent intended to seal any punctures and at least partially applied to the surface of an inner cavity (2) of the end-of-use pneumatic tyre; the system (1) comprises an applicator device (6), which is provided with at least one nozzle (13) which dispenses a cryogenic fluid, preferably liquid nitrogen, upon the (SAL) layer of sealing agent in such a way that the (SAL) layer of sealing agent reaches the solid state; a device (14) for the removal of the (SAL) layer of solid sealing agent that is provided with a tool (16) for removing the (SAL) layer of solid sealing agent by means of mechanical abrasion; and a circuit (17) for suctioning the solid sealing agent removed by the tool (16).

A cleaning assembly may include a chuck. The cleaning assembly may include a plurality of lift pins positioned proximate to the chuck. The plurality of lift pins may be configured to engage a cleaning substrate and translate the cleaning substrate to allow the cleaning substrate to capture one or more particles from the surface of the chuck via at least one of electrostatic attraction or mechanical trapping when the cleaning substrate is positioned in the second position. The cleaning assembly may include a replaceable top skin coupled to the chuck and configured to capture the one or more particles.
