A machine tool has a cover that prevents chips generated by machining and cutting fluid from scattering around and a plurality of movable nozzles with liquid discharge directions thereof being movable so as to wash out chips that have adhered to or accumulated on an inner surface of the cover. The machine tool is capable of changing a discharge direction of each of the movable nozzles individually. The machine tool compares the state of the inside of the cover before start of machining with the state of the inside of the cover after chips are generated to determine an adhesion or accumulation state of chips. The machine tool thus calculates the liquid discharge direction to wash out chips from the movable nozzles based on a result of the determination.

The invention relates to a treatment device for workpieces, having the following: a treatment chamber (1); a shaft (2) which extends through a wall of the treatment chamber (1) into the treatment chamber and which is mounted in a rotatable manner; an electric treatment unit (3) which is secured to the shaft (2); and a power supply arrangement (6) with a first supply line (61), an electric coupling (63, 64), a second supply line (62), and an actuating unit (7). The electric coupling (63, 64) has a first coupling element (63), which is secured to the shaft (2) outside of the treatment chamber (1), and a second coupling element (64). The first supply line (61) connects the electric treatment unit (3) to the first coupling element (63), and the second supply line (62) is connected to the second coupling element (64). The actuating unit (7) is designed to actuate the coupling (63, 64) in order to bring the second coupling element (64) into contact with the first coupling element (63) or release the second coupling element (64) from the first coupling element (63).

An assembly for preparing and/or painting large surface areas, such as building walls, includes a mounting device and a movable applicator. The mounting device provides a mechanism for positioning the movable applicator adjacent the wall surface, and allowing the movable applicator to move along the wall surface. The assembly can be mounted to a wall. The assembly preferably uses existing roof anchor points of the wall, for preparing and/or painting a large surface of the wall. In an alternative embodiment, the mounting means can move the movable applicator along the wall surface.

An apparatus and method for cleaning the interior of an above ground storage tank includes a nozzle assembly mounted to a cover on the storage tank sidewall having a horizontally extending wash pipe fixedly and a suction pipe for recirculation of spent fluids. The wash pipe has an interior segment which can be extended to a tank floor and is configured with a bend to extend along the tank sidewall to which is attached a submersible swivel joint fitted with a choked nozzle. The nozzle assembly is attached to a control assembly so that the direction of flow from the nozzle may be manipulated by rotation of the swivel joint from the exterior of the storage tank. The nozzle also may be adjusted so the direction of flow may follow the angle of the tank floor.

A wire arc spray system (100) includes a plurality of arc spray subsystems (130) mounted to a movable carriage (120) on an x-y robot (110). Each arc spray subsystem includes a wire drive (132) that provides wire (133, 134) to a spray head (138) through a pair of lead cables (136). The spray heads are mounted for circular motion, such that the molten spray is applied to an underlying substrate in a swirling pattern. In one embodiment, the spray heads are mounted to a distal end of a rod (164) that extends through a swivel ball joint (166) and engages an eccentric link (162) fixed to a motor (160). The system applies an overlapping pattern of molten spray to provide excellent non-skid and adhesion properties. The system is particularly suited to spray coating with a wire comprising a hollow metallic portion and a core having ceramic particles.

A device is provided for repairing erosion damage to a bore of a railgun with metal powder. The bore has a surface contour that extends longitudinally of the railgun. The device includes a housing, a profilometer sensor and a nozzle. The housing has a configuration that conforms to the surface contour and an upstream face on a longitudinal end. The profilometer sensor mounts to the upstream face to measure depth of the erosion and indicate a divot in the bore that involves repair to match the surface contour. The nozzle mounts to the upstream face to spray the metal powder from a reservoir within the housing in response to the divot indicated by the profilometer.

Apparatus and a method for removing particulate matter from an enclosure having an internal space and an opening into the internal space. The apparatus includes: a cover positionable over the opening; an inlet conduit that extends through the cover and is adapted to direct gas from a gas source to a gas outlet within the internal space so that particulate matter within the internal space is dislodged. Gas and entrained particulate matter is drawn from the internal space firstly through an outlet conduit and the particular matter is separated. Concentration of particulate matter in gas leaving the enclosed space is sensed and its value displayed to an operator so that operation can continue until a satisfactory value of the concentration is achieved. The gas outlet may be comprised in an elongate lance that is passed through the cover and can be manipulated by a user. The lance may display data.

The invention relates to a cooling lubricant nozzle carrier (100) for a grinding machine (1), the cooling lubricant nozzle carrier (100) having a central arm (150) and two side arms (130, 140) arranged on the central arm (150) such that they can move relative to the central arm (150), and the cooling lubricant nozzle carrier (100) having at least two cooling lubricant nozzles (110, 120), at least one of which is arranged on each of the side arms (130, 140), wherein the side arms (130, 140) are each movably mounted relative to the central arm (150) in such a way that the cooling lubricant nozzle (110, 120) arranged on a particular side arm (130, 140) moves together with the side arm (130, 140) on a circular path when the side arm (130, 140) in question moves; a grinding machine having such a cooling lubricant nozzle carrier; and a method for operating such a grinding machine.

The present disclosure provides an automated dispenser and spray device configured to apply a cleaning solution to a user's body in an automated fashion as they take a shower, freeing their hands. The device comprises an oscillating arm assembly of adjustable height with a spray nozzle at the end. Various parameters of the spray can be adjusted to a user's preferences via a control module and interface so that they can simply focus on cleaning themselves as the solution is applied.

Embodiments relate to surface treating a substrate, spraying precursor onto the substrate using supercritical carrier fluid, and post-treating the substrate sprayed with the precursor to form a layer with nanometer thickness of material on the substrate. A spraying assembly for spraying the precursor includes one or more spraying modules and one or more radical injectors at one or more sides of the spraying module. A differential spread mechanism is provided between the spraying module and the radical injectors to inject spread gas that isolates the sprayed precursor and radicals generated by the radical injectors. As relative movement between the substrate and the spraying assembly is made, portions of the substrate is exposed to first radicals, sprayed with precursors either one of the spraying modules or both spraying modules using supercritical carrier fluid, and then exposed to second radicals again.
