A pneumatic washing and drying machine including a washing chamber and a liquid reservoir in fluid communication with the washing chamber, the washing chamber internally including spray nozzles directed towards at least a part to be washed arranged within the washing chamber and configured to spray a fluid so as to wash the at least one part and then air so as to dry the at least one part, the pneumatic washing and drying machine further includes a pneumatic unit powered by a compressed air supply to provide a liquid from the liquid reservoir to the spray nozzles via the air from the compressed air supply, and then provide air from the compressed air supply to the spray nozzles.

A cleaning device that includes a washing frame having one or more spray arms having one or more spray apertures for discharging a liquid in one of a plurality of directions towards a target entity. At least one portion of the washing frame is coupled to a vehicle. One or more spray nozzles may be coupled to the one or more spray apertures. The one or more spray nozzles may be selectively adjusted toward the target entity.

In a spraying process for coating a substrate with a substance atomised in a stream of gas, a spray head is used to generate a stream of gas that acts upon the substrate. The substance is present in a syringe-like application container equipped with an application tip. The application tip of the application container containing the substance is introduced into the stream of gas outside the spray head at a distance therefrom and transversely with respect to the main direction of flow of the stream of gas, and the substance is introduced from the application container into the stream of gas at that location.

The invention is directed at systems and methods which provide for effective cleaning and drying of vehicles of different shapes and sizes. The invention in one example includes a vehicle washing apparatus comprising a conveyor system to move a vehicle along a path, and a bridge assembly supported above a vehicle and moveable along the length thereof. At least one trolley assembly is operatively supported by the bridge assembly and is moveable in a direction generally transverse to the movement of the bridge assembly. At least one cleaning arm assembly for delivering cleaning fluid to or for brushing the surface of a vehicle is operatively supported by the at least one trolley assembly or bridge. The cleaning arm assembly is moveable with the bridge assembly along the length of the vehicle, and transversely with the at least one trolley assembly to adjust the location of the cleaning arm relative to the vehicle, wherein the bridge assembly moves in association with movement of the vehicle to position the cleaning arm assembly adjacent at least a portion of the front, sides and rear of the vehicle as it moves along the path. A variable impact or patterning spray arm or drying system is also provided.

A paint rack having an attachment support bar, three leg portions, and three grate attachment portions, the three grate attachment portions matably attachable to a floor grate, the three leg portions mounted on top of the three grate attachment portions and extending upwardly from the grate attachment portions, the attachment support bar connected to the three leg portions, and extending upwardly from the three leg portions.

A device for measuring undulation of a brake disc in a railway wheel with brake discs includes a wheel support supporting a hub's bore of the railway wheel; a first displacement gauge for measuring a height displacement of the brake disc frictional surface for one round to follow rotation of the wheel support; and a second displacement gauge for measuring a height displacement of a railway wheel rim surface for one round to follow rotation of the wheel support. A computing unit calculates a difference between maximum and minimum values of the height displacement of the frictional surface by acquiring measurement data from the first displacement gauge, calculates a difference between the maximum and minimum values of the height displacement of the rim's surface by acquiring measurement data from the second displacement gauge, and derives a difference between the both calculated differences as brake disc undulation.

The invention relates to a method for coating a shaped component (3) having an inner side (12) and an outer side (9) with a first coating material on the inner side (12) and with a second coating material on the outer side (9), wherein a strip (13) at least of the outer side (9) remains uncoated in the region of a circumferential edge (6) that adjoins the inner side (12) and the outer side (9), and the first and second coating materials cannot be mixed with each other, in which method the component (3) is introduced into a holder and held fixed in its position there while the coating materials are applied one after the other by means of a spraying robot. The method is simplified and allows a reduction in the number of handling steps in that a plate (1) is used as the holder, said plate having a recess (2) with profiling (4, 5) formed above the height thereof, into which the component (3) is placed without the use of a movable fastening means, and the recess (2) is sealed off in such a manner that the first coating material that is sprayed from a first side (7) of the plate (1) does not reach the outer side (9) of the component and the second coating material that is sprayed from the second side (8) of the plate (1) does not reach the inner side (12) of the component (3). The method is further characterized in that any overspray is extracted from the respective side and in that the second coating material is sprayed in such a manner that the strip (13) of the component (3) always lies in a spray shadow formed by the profiling (4, 5).
