A fluid injector comprising a coil arranged to drive a pump from a first state to a second state when energized, so as to pump a dosing fluid; a PN junction electrically arranged across the coil to discharge energy stored in the coil when the voltage across the coil is above a threshold. In one particular embodiment, the fluid injector is a selective catalytic reduction dosing fluid injector.

A device (1) for applying a coating of hardenable plastic to an inner side of a wall of a tubular construction, for example a sewage pipe, includes a supply chamber (3) for containing a hardenable plastic, a delivery head (2) including an outlet (5) for letting out the hardenable plastic from the delivery head (2), and a pump (11) for transporting the hardenable plastic from the supply chamber (3) to the outlet (5). During use, the outlet (5) is positioned at various angular positions with respect to a rotation axis (40), so that the entire circumference of the inner side of the wall of the tubular construction can be provided with the hardenable plastics coating. The supply chamber (3) includes a flexible wall for optimal maneuverability of the device (1), whereby broad application of the device (1) is possible.

An imprinting apparatus includes: a coating unit which coats a substrate with ink including a photocurable resin in a diluent; a pressing unit which presses the ink with an imprint stamp including an uneven pattern; and a light source which irradiates light to the ink, which is in a pressed state, and cures the photocurable resin. The coating unit, the pressing unit and the light source move relative to the substrate in a processing direction. The coating unit is located ahead of the pressing unit in the processing direction.

Transportable modular coating systems include a first transportable coating module comprising at least one first removable wall, a second transportable coating module comprising at least one second removable wall, wherein the first and second transportable coating modules are joinable when the first and second removable walls are removed, and a plurality of coating components fixed within the first and second transportable coating modules that combine to create a coating operation. The transportable coating module further includes a transportable control module that comprises a control system that operably connects to the plurality of coating components to operably control the coating operation.

A sprinkler assembly with a nutating distribution plate that tilts and/or rotates upon water impinging the distribution plate. A deflector assembly includes the distribution plate and a base. A body of the sprinkler assembly includes a base retainer surface and a flanged bolt which combine to create a portion of a confinement structure. A portion of the deflector assembly is located within the confinement structure to limit a range of movement of the distribution plate. A nozzle subassembly includes a nozzle and retainer supporting a seal. The nozzle alone or in combination with the retainer can be removed from the sprinkler assembly. The sprinkler assembly can be disassembled and reassembled with minimal tools and effort for servicing. The distribution plate and the base can have mass properties optimized to improve sprinkler performance by reducing vibration, improving uniform water distribution, and reducing fine water droplet generation upon water stream impingement on the distribution plate.

A method of supporting a rotating member of a tailstock includes rotating a rotating member coupled to a workpiece support slidably mounted in a housing of the tailstock, causing the rotating member to shift along a longitudinal axis in a first direction, and measuring an amount of vertical displacement of the rotating member.

The invention provides a high pressure nozzle (1), comprising: .Math.a longitudinal housing (2) having a liquid inlet end (3) and a liquid outlet end (4) opposite to the liquid inlet end and comprising an internal channel (8) running from the liquid inlet end to the liquid outlet end, .Math.a nozzle head support shaft (9), rotatably arranged partially in the internal channel (8) and comprising a liquid channel (22) in fluid communication with the internal channel, and .Math.a rotary nozzle head (10) supported on the nozzle head support shaft and arranged outside the housing, wherein the rotary nozzle head is arranged to rotate about a longitudinal axis of rotation (A) to provide a rotating spraying of liquid jetted from the rotary nozzle head, characterized in that the high pressure nozzle comprises an axial pressure compensator (12) arranged in the internal channel, wherein the axial pressure compensator is arranged to substantially compensate axial pressure force from liquid entering the channel at the liquid inlet end.

The invention relates to a device for moistening and/or fertilizing plants (1), comprising a movable spray lance (3) with at least one spray nozzle (4) arranged on the spray lance (3), wherein a preferably linear guide rail (2) is provided, wherein the spray lance (3) is movably guided in the guide rail (2) in a trajectory extending parallel to the guide rail (2) and extends substantially normal to this trajectory, and wherein a drive, preferably a linear drive (11), is arranged for moving the spray lance in the area of the guide rail (2). The invention further relates to a system for cultivating plants without a substrate, comprising the device according to the invention.

What is disclosed is a sprinkler head having a nozzle configured for spraying a fluid, such as irrigation water, at a distribution disk. The distribution disk is configured to rotate on an upper axle. The upper axle is housed within an upper axle housing. The upper axle housing is configured to rotate about a lower axle. The dual axle provides for two different rotation axles of the distribution disk in operation. Preferably a speed control device can be positioned to control the speed of rotation of one axle or both axles.
