Please replace the Abstract at page 41 with the following replacement paragraph: A nozzle, for spraying materials, in particular, dispersions, emulsions, or suspensions.

A liquid discharge device includes a liquid discharge head including nozzles configured to discharge a liquid, a carriage mounting the liquid discharge head and movable, a wiper configured to wipe a nozzle surface of the liquid discharge head, and a wiper mover configured to hold and move the wiper between a facing position at which the wiper faces the nozzle surface and a standby position at which the wiper does not face the nozzle surface. The carriage movably holds the liquid discharge head and the wiper mover as a single unit.

The invention relates to a nozzle device (100) for producing a three-dimensional component made of a material, in particular a shotcrete component made of concrete, a material application system (1), a manufacturing system (200) and a method for producing a three-dimensional component made of a material, in particular a shotcrete component made of concrete. In particular, the invention relates to a nozzle device (100) for producing a three-dimensional component made of a material, in particular a shotcrete component made of concrete, comprising a nozzle unit (101) with a material guide (102), which has a material inlet (104) for introducing a material, in particular a concrete, and a nozzle element (106) fluidically coupled to the material inlet (104) for applying the material, in particular the concrete, which is preferably arranged replaceably on the nozzle unit (101).

An improved device for adjusting spray guns in an IC spray machine. Adjustments may be done using electro-mechanical or pneumatic actuators, and may rotate the nozzles toward an evacuation hood for cleaning, etc. Two actuators are used per spray gun, one mechanically engaged to a slide which moves the gun in translation (traversing in the X dimension), one which is mechanically engaged to a bracket which in turn is mechanically engaged to the gun mount, so the gun may be either moved or rotated. In addition, a Z-axis beam allows control in depth by an additional actuator/motor.

A powdering system, having a working configuration and a cleaning configuration and including a powder reservoir, including a supply chamber receiving powder; a sprayer, including a powder applicator, and a cleaning inlet, fluidly connected to the supply chamber such that, in the cleaning configuration, a cleaning air supply source can be connected to the cleaning inlet so as to circulate cleaning air in the supply chamber, wherein the powder reservoir includes a discharge opening, arranged through a wall of the supply chamber and opening into the supply chamber, and a movable plug, which is movable between a closing position, in the working configuration, and an open position, in the cleaning configuration, such that the circulation of cleaning air causes residual powder to be discharged through the discharge opening.

A paint sprayer includes an end bell, a motor connected to the end bell, a pump drive connected to the end bell, a pair of protrusions attached to an extending from the end bell such that each protrusion is cantilevered from the end bell, and a pump assembly comprising a pair of mounting holes and containing a piston. The pair of mounting holes is adapted to receive and slide onto the pair of protrusions to mount the pump assembly on the end bell as well as slide off of the pair of protrusions to remove the pump assembly from the end bell. The pump drive is configured to covert rotational motion output by the motor to reciprocal motion. The pump assembly is configured to pump paint when reciprocated by the pump drive while mounted on the end bell.
