An apparatus for applying a first fluid to an advancing substrate comprising a nozzle body made, at least in part, using an additive manufacturing method. The nozzle body comprises a fluid orifice for receiving the first fluid; a conduit in fluid communication with the fluid orifice for receiving the first fluid received by the fluid orifice; a passageway in fluid communication with the conduit for receiving the first fluid received by the conduit; and a slot in fluid communication with the passageway for applying the first fluid to the advancing substrate. A method for making an apparatus comprising a nozzle body is also provided, comprising: sequentially forming, from at least one material using an additive manufacturing method, a plurality of layers in a configured pattern corresponding to a shape of at least one of an upper nozzle assembly member or of a lower nozzle assembly member of the nozzle body.

An irrigation nozzle with a rotating deflector is provided whose rotational speed may be controlled by a friction brake. The nozzle may also include an arc adjustment valve having two portions that helically engage each other to define an opening that may be adjusted at the top of the sprinkler to a desired arcuate length. The arcuate length may be adjusted by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a radius reduction valve that may be adjusted by actuation of an outer wall of the nozzle. Rotation of the outer wall causes a flow control member to move axially to or away from an inlet.

A sprinkler includes a pop-up deflector plate that is engageable with a brake assembly in an extended position. A brake module is secured to a sprinkler body and includes a rotatable connector coupled with the brake assembly. The pop-up deflector plate is disposed adjacent the nozzle and engages the rotatable connector in the extended position.

In one aspect, a sprinkler is provided having a nozzle, a deflector that receives fluid flow from the nozzle, and a friction brake assembly that controls rotation of a deflector. The friction brake assembly is releasably connected to the frame in order to enhance serviceability of the sprinkler. In another aspect, a sprinkler is provided having a frame, a deflector rotatably connected to the frame, a nozzle, and a nozzle socket of the frame. The nozzle and nozzle socket have interlocking portions that releasably connect the nozzle to the frame. The nozzle may be easily removed for servicing. Further, the nozzle socket can be configured to receive a plurality of nozzles having different flow characteristics. A nozzle can be selected and utilized with the sprinkler according to the desired application for the sprinkler.

A workpiece processing method includes a resin coating step of coating a resin on a front surface of a workpiece, a resin curing step of applying an ultraviolet ray to the coated resin to be cured, a resin grinding step of grinding the cured resin with grinding stones to be flattened, and a workpiece grinding step of holding the flattened resin side of the workpiece on a chuck table and grinding the back surface of the workpiece with grinding stones. In the resin grinding step, grinding is performed while cleaning the resin stuck to the grinding stones. Accordingly, it is possible to grind the resin coated on the front surface of the workpiece and the back surface of the workpiece in the same apparatus.

According to one example, a method may include determining a desired pattern of fluid to be applied to a substrate, controlling a first array of fluid applicators to apply fluid to the substrate to form a first portion of the pattern, in which an applicator of the first array of fluid applicators spans a section of the substrate that includes portions of the substrate both in and out of the pattern. The method may also include controlling the first array of fluid applicators to cause the applicator to not apply fluid to the section of the substrate and controlling a second fluid applicator to apply fluid to the section of the substrate, the second fluid applicator being separately movable from the first array of fluid applicators.

A rotary nozzle sprinkler includes a base assembly with a bearing, a stem mounted rotatably in the bearing, and an elbow coupled at a proximal end to and rotatable with the stem and including an elbow bend. A nozzle is secured to a distal end of the elbow, and a diffuser assembly including a brake mechanism is cooperable with the elbow. By positioning the nozzle downstream of the elbow, the sprinkler can achieve a greater throw radius.

An irrigation nozzle with a rotating deflector is provided whose rotational speed may be controlled by a friction brake.
