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.

An irrigation system with transient state speeds of movement achieves and maintains substantial straight alignment of multiple interconnected spans with continuous movement over a range of speeds in a forward and reverse movement direction. A variable-speed drive controller monitors and processes the output of the corresponding alignment detector and, based on the output of the alignment detector, selects from memory and continuously furnishes to the corresponding span motor a predetermined progressively increasing speed profile or a predetermined progressively decreasing speed profile.

The present disclosure provides a spraying device and a coating method. The spraying device comprises a first spray unit and a second spray unit. The first spray unit is configured to spray a first solution for wetting a surface of a substrate, and the second spray unit is configured to spray a second solution for coating the surface of the substrate. During spraying, the second spray unit and the first spray unit advance in the same direction and the second spray unit is arranged behind the first spray unit in the advancing direction. In the present disclosure, the coated liquid diffuses across the surface of the substrate more quickly and uniformly, the alignment film formed on the surface of the substrate has a uniform thickness, thus avoiding mura due to an alignment film with a non-uniform thickness and improving quality of the display panel.

A paint roller cover cleaner including an enclosure for a roller cover, a high pressure pump and a nozzle supplied with pressurised fluid which directs a jet of fluid at the nap of the roller cover to rotate the roller cover and facilitate cleaning. In one embodiment a carriage moves the nozzle along the length of the roller cover to effect cleaning along the length of the roller cover. In another embodiment a plurality of controllable nozzles are provided at intervals along the length of the roller cover. In another embodiment the nozzle includes an inner sleeve and an outer sleeve which relatively rotate to align apertures in the respective sleeves to produce jets sequentially along the nozzle.

A water jetting nozzle includes a housing assembly and a hollow shaft extending longitudinally within the housing assembly and having a shaft proximal end adapted to be connected in fluid communication with a high pressure water line, and a shaft distal end. A rotating head is secured to the shaft distal end, the rotating head including at least one water jet orifice. A magnetic rotor is seated on the shaft and a conductor sleeve is located within the housing assembly, the conductor sleeve having a longitudinally extending bore adapted to receive the magnetic rotor. A longitudinal position of the conductor sleeve is selectively movable relative to the magnetic rotor between a first position in which the magnetic rotor is generally located within the bore, and a second position in which the magnetic rotor is at least partially external of the bore.

Methods and systems are provided for a lateral flow test device. In one example a lateral flow test device may include a housing comprising an upper first portion and a lower second portion, the lower second portion further including a planar surface, a nitrocellulose matrix strip, the strip disposed on the planar surface, and one or more ligand regions included in the strip, the ligand regions comprising one or more ligands. The strip may be formed from a liquid polymer mixture dispensed onto the planar surface via a dispensing device positioned vertically above the planar surface.

An anchoring device for a self-propelled irrigation system includes a drive assembly that drives a soil auger into the ground to anchor a drive tower of the irrigation system. The soil auger is rotatably driven about a vertical axis and movable vertically relative to the drive tower. The soil auger includes a lower tip, a multi-sided head at an upper end, and a helical screw portion between the lower tip and the upper end. The drive assembly includes a sleeve member with an inner surface that mates with the head of the soil auger and allows the soil auger to slide within the sleeve member while rotating together with the sleeve member. A bit cleaner assembly is arranged to engage the helical screw portion of the soil auger to clean soil from the auger and to cause the auger to move vertically relative to the sleeve member upon rotation.
