A dust containment assembly includes a box that has an open side which can be placed against a gypsum wall panel. The box has a pair of hand openings extending through the box to facilitate a user to access the area of gypsum wall panel that is covered by the box. The box is comprised of a fluid impermeable material to inhibit dust from escaping the box. A pair of sleeves is each coupled to the box and each of the sleeves is aligned with a respective one of the hand openings. Each of the sleeves can insertably receive a respective one of the user's arms for the user to work on the area of the gypsum wall panel that is covered by the box. A plurality of legs is each movably disposed on the box to retain the box at a desired height on the gypsum wall panel.

The air blow nozzle includes a nozzle body configured to be connected to an air compressor one end thereof and includes an air discharge portion another end thereof, the air discharge portion is capable of discharging compressed air supplied from the air compressor. The air discharge portion is configured to be movable to a position that does not correspond to an upper communication hole as the nozzle body is slid to one side. The nozzle body includes a nut configured to position the air discharge portion in a predetermined position near a rotary holder as the nozzle body is slid to another side.

A system for collecting and disposing waste from a material cutting machine may include a tray apparatus at least partially insertable into the cutting machine. The tray apparatus has an interior and an open top for receiving waste from the cutting machine. The tray apparatus may have a collection condition for holding waste in the interior and a disposal condition for dumping waste from the interior. The tray apparatus may include a base structure and a pan structure movably mounted on the base structure to move between a collection position and a disposal position. The tray apparatus may define a pair of fork pockets with each fork pocket being configured to receive a portion of a lift fork to facilitate lifting of the tray apparatus by equipment having lift forks.

A blind cutting machine can include a cutting system having a cutting blade and a member configured to automatically move in response to completion of a cutting process. The blind cutting machine can include a dust mitigation system that includes a vacuum and a separator fluidly connected with the vacuum. The separator is configured to separate debris and air drawn into an inlet of the vacuum. The dust mitigation system can include a canister fluidly connected to the separator. The canister is configured to receive the debris. A door of the canister is configured to automatically move with the member. In a first state, the door seals the canister. In a second state, the door is removed from the canister.

An NC lathe 1 for machining a work W includes a housing 11, a chip bucket 8 that is placed inside of the housing 11 in order to receive chips produced when the work W is machined, an opening formation portion 112 that is provided in the housing 11 and has an opening 1121formed therein through which the chip bucket 8 can be pulled out to the outside of the housing 11, and an opening cover 15 that is detachably attached to the housing 11 so as to close the opening 1121 in an attached state attached to the housing 11, wherein the opening formation portion 112 has a slit 1122 that is formed continuously with the opening 1121 so as to extend in a width direction of the opening 1121, and that allows the opening cover 15 removed from the housing 11 to be inserted into the housing 11.

Provided is a cutting fluid tank for a machine tool, with which the operator's time and effort for cleaning are reduced and the maintainability is enhanced, without entailing an increase in size. In a tank body, a cutting fluid flow channel having a spiral shape and extending from a tank center region to a tank outer peripheral region is formed by a flow channel forming plate. An inflow port into which a cutting fluid from inside a machining chamber flows is provided at an outer peripheral region of the lid, whereas an outflow port to take out the cutting fluid in the tank body to an outside is provided at a center region of the lid. A pump to pump up and supply the cutting fluid to the machining chamber is provided at the outflow port.

A device for collecting and maintaining debris from a wall (e.g., drywall) is described. In one example of the device of the present invention, two faces of the device each have a beveled edge, and are positioned at an obtuse angle with respect to one another. A corner apparatus may be positioned at a side edge of each face, and may permit the connection of the device to identical or similar devices. The device may be positioned on a floor adjacent to a bottom of a wall. In another example of the device of the present invention, two faces of the device each have a beveled edge, and are positioned at an acute angle with respect to one another. The device may be positioned on a wall above a floor.

A scrap collection assembly for use with a fiber placement machine, including a scrap bin configured to receive scrap pieces of composite tape; a first roller assembly, including a roller configured to engage one side of a scrap piece of composite tape, coupled to the scrap bin; a second roller assembly, including another roller configured to engage an opposite side of the scrap piece of composite tape, coupled to the scrap bin, such that the rollers move to engage opposite sides of the scrap piece, pull the scrap piece from a fiber placement machine, and deposit the scrap piece in the scrap bin.

A deflector apparatus catches debris and deflects coolant spray in a coolant collection area of machine tools having an extended drawtube or bar feed area such as CNC lathes. The deflector apparatus encloses the coolant collection area by covering the opening or access to the area with a door and attached basket. The basket extends into the coolant collection area at an incline relative to the door and interrupts coolant and debris entering the coolant collection area from the drawtube, causing the debris to collect within the basket and allowing coolant to filter through a grate positioned on a lower surface of the basket. A flange with an outer seal extends along part of the lower edge of the door to create a seal between the door and the opening to the coolant collection area. Additional features include a locking mechanism, handle, and reinforcement plate.
