A suspended pipe assembly comprising a first suspended pipe, a second suspended pipe, a third suspended pipe, and a number of suspenders for suspending the pipes from an elevated pipe or pipes of a mobile irrigation system or other fluid distribution system. The first suspended pipe and second suspended pipe are connected together via a fixed joint. The second suspended pipe and third suspended pipe are connected together via a live joint such that the second suspended pipe and third suspended pipe can expand longitudinally relative to each other. Additional suspended pipes can be connected to each other via alternating fixed and live joints. The suspenders allow the suspended pipes to expand longitudinally relative to the elevated pipe and prevents the suspended pipes from warping side-to-side.

A coating device for coating a coating liquid onto a substrate includes: a coating head having a coating-liquid outlet, adapted to move with respect to the substrate along a first axial direction and capable of coating the substrate with coating liquid through the coating-liquid outlet; and adjustment unit connected to the coating head and including a movable pad disposed proximal to the coating-liquid outlet and adapted to move along a second axial direction for adjusting the size of the opening of the coating-liquid outlet; and a drive assembly connected to the adjustment unit for controlling the adjustment unit to move along the second axial direction. Additionally a coating method is provided.

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.

An application system for depositing a fluid product on a surface. The application system comprises a frame mounted on a locomotive system ensuring the displacement of the frame over the surface, a tank mounted on the frame and receiving the fluid product to be applied, and an application head fluidically connected with the tank via a supply nozzle. The application system comprises a guiding system which comprises detectors to detect the obstacles in the environment of the application system. Such an application system allows for an even application of the fluid product over the entire surface.
