A processing apparatus used in processing a workpiece having a device in each of a plurality of regions that includes a chuck table holding the workpiece, positioning means positioning the workpiece before grinding, resin coating means including a rotatable spinner table for coating the workpiece with a resin, cleaning means, a grinding unit, and a transfer unit. The transfer unit includes a first transfer unit transferring the workpiece from the positioning means to the spinner table and from the spinner table to the chuck table, a second transfer unit transferring the workpiece from the chuck table to the cleaning means, and a front/back surface inversion transfer unit taking over the workpiece from the cleaning means to the second transfer unit.

A mechanism is described to resist or prevent rotation of portions of an irrigation sprinkler riser when in its lowered or popped-down position. Hence, when a pedestrian walks over a lowered sprinkler or a lawn mower rolls over a sprinkler, for example, the riser will remain fixed in its rotational orientation relative to its outer body and surroundings. By resisting or preventing this rotation, this rotational locking mechanism prevents damage to the internal transmission, gears, and arc trip mechanisms of the sprinkler, as well as prevents the watering arc from being accidentally adjusted.

Methods of dispensing fluid are disclosed. A first applicator is positioned above a first dispense site at a first dispense region of a first electronic substrate by moving the first applicator using a primary positioner. A second applicator is simultaneously positioned above a first dispense site at a second dispense region of the first electronic substrate by moving the second applicator together with the first applicator using the primary positioner and moving the second applicator relative to the first applicator using a secondary positioner. It is then determined that the first or the second dispense region is misaligned relative to the other of the first or the second dispense region. Fluid is dispensed from the first applicator while moving the first applicator using the primary positioner to form a first fluid pattern at the first dispense region and fluid is simultaneously dispensed from the second applicator while moving the second applicator using the primary positioner and the secondary positioner.

A sprinkler module is cooperable with a sprinkler nozzle unit supporting a sprinkler nozzle to define a sprinkler configuration. The sprinkler module includes a cage attachable to the sprinkler nozzle unit and including a pair of struts, a cap connected to the cage via the pair of struts, and a deflector plate cooperable with the sprinkler nozzle and rotatably secured between the cap and the cage. The deflector plate includes a hub extending through the cap. A plate gear with gear teeth is secured to the hub and is rotatable with the deflector plate, and a cover assembly is connected to the cap. The cover assembly includes a brake gear coupled with a brake assembly, where the brake gear is disposed in a path of the gear teeth.

A wastewater spray distribution apparatus is operative to distribute wastewater produced by a sewage treatment system (10) onto a ground level (22) through operation of sprayers (118, 260). The exemplary sprayers include a manifold (142, 262) that includes outlet nozzles (158, 264) that can be readily removed and replaced. The exemplary manifold further includes interior areas bounded by surfaces that slope continuously downward from the outlet nozzles to the manifold inlet to assure the draining of water therefrom. Each of the nozzles include a base (140) which includes brake (207). A brake is provided in each nozzle and is adjustable to provide brake force to limit rotational movement produced by the thrust of water passing from the outlet nozzles to assure that the sprayer operates at the appropriate rotational speed. Alternative arrangements include manifolds including fixed or adjustable flaps and radially outwardly adjustable arms to adjust rotational properties.

A rotary atomizer turbine is provided, the turbine including a turbine wheel with multiple turbine blades, a blade duct containing the turbine blades and being delimited radially by a duct wall, a braking air nozzle, a driving air nozzle and an outlet region at the outlet of the driving air nozzle. The outlet region is delimited at the outside by the duct wall of the blade duct and at the inside by the turbine blade respectively passing through it. The blade duct is delimited radially at the inside opposite the braking air nozzle by a stationary flow barrier. Furthermore, the outlet region of the individual driving air nozzles is a divergent cross-sectional region which widens in the flow direction and rotates with that turbine blade passing the driving air nozzle.

A system and method for coating an expandable member of a medical device comprising a support structure to support the expandable member and a dispenser positioned with at least one outlet proximate a surface of an expandable member. A drive assembly establishes relative movement between the at least one outlet and the surface of the expandable member to apply fluid on the surface of the expandable member along a coating path. A guide maintains a substantially fixed distance between the at least one outlet and the surface of the expandable member during relative movement therebetween by displacing the expandable member relative to the at least one outlet.
