A road striping removal and particulate capturing combination system includes a chassis having a front end and a rear end. A plurality of wheels is rotatably coupled to the chassis and extends downwardly therefrom. The chassis includes an open bottomed housing having an upper wall and a perimeter wall that is attached to and extends downwardly from the upper wall. A particulate conduit extends through the upper wall. A particulate nozzle is fluidly coupled to the particulate conduit. The particulate conduit delivers particulate under pressure to the nozzle such that the particulate is ejected from the nozzle toward road striping as the striping passes under the upper wall. A vacuum conduit is fluidly coupled to an interior space bounded by the housing. The vacuum conduit is fluidly coupled to a vacuum to suction the particulate after the particulate has struck the road surface.

A method for treating a surface of a fibre composite component, wherein an abrasive removal of the surface of the fibre composite component takes place by blasting a removing agent transported by a gaseous transporting fluid onto the surface of the fibre composite component by a feed nozzle and a suction extraction of the removing agent and material removed by the removing agent takes place by an extraction nozzle arranged in the region of the feed nozzle.

An abrading device includes a funnel and an outlet orifice disposed within the funnel for passage of abrasive material, where a distance between the outlet orifice and a bottom end of the funnel is adjustable. An exhaust tube is coupled to the funnel for withdrawal of spent abrasive material from the funnel.

A peening device for treating a component includes a shot media propulsion source configured to propel a quantity of shot media. The device also includes a plurality of treatment enclosures each selectively coupleable to the shot media propulsion source. Each of the treatment enclosures has a shape complementary to a corresponding one of a plurality of portions of the component, such that each treatment enclosure and the corresponding portion cooperate to enclose the shot media.

A pipeline field joint abrasive blast cleaning machine is disclosed in which direct contact between the pipe to be cleaned and drive rollers of the machine ensure a constant, known distance exists between the blast nozzles of the machine and the pipe surface. This ensures uniform application of abrasive matter to ensure uniform cleaning of the pipe surface.

Spray apparatus and uses thereof are described herein. A vacuum spray nozzle apparatus may include a first tube in fluid communication with a fluid source, a rotor coupled to the tube, a conduit in fluid communication with the passages of the first tube, and a second tube coupled to the conduit, the second tube being in fluid communication with a vacuum source. The rotor is in fluid communication with the pressurized fluid source. The conduit is substantially arched or angled such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis, and when pressurized fluid is ejected from the outlet, during use, rotates the conduit. The vacuum spray nozzle apparatus is configured to remove components from a material through the second tube when a pressure of the system is reduced using the vacuum source.

A pickling tool configured for pickling a surface of an element, comprising a supply conduit delimiting a supply channel configured to be in pneumatic communication with a source of compressed air laden with a powder of an abrasive product, a removal conduit delimiting a removal channel configured to be in pneumatic communication with a suction source, and a nozzle having an opening that communicates with an exterior and is configured to face the surface, wherein the nozzle is in pneumatic communication with the supply channel and the removal channel. Such a tool thus allows the passage of a flow of air for spraying the abrasive and the suction of the abrasive and of the powder arising from abrasion.

The temperature of the chamber housing a shot wheel of a shot blaster is controlled by positioning a fan exterior to the chamber that creates air flow across a mounting plate defining the chamber. The air flow created by the fan may also pass around the bearing surrounding the drive shaft that turns the shot wheel.
