An apparatus for producing prills includes a hollow body rotatable about a first axis, the body having a wall rotationally symmetrical around the first axis forming an interior space, the wall including nozzles for generating jets of liquid in a radially outward direction with respect to the first axis when rotating the hollow body; a second body disposed in the hollow body forming a gap between the hollow body and the second body; a liquid inlet for supplying a flow of liquid to the gap; a rotary drive unit for driving the hollow body around the first axis; a reciprocating drive-unit for reciprocally moving the hollow body and/or second body with respect to the other body along the first axis of rotation for applying reciprocal pressure on the jets; and a coupling for enabling relative rotations between the one of the hollow body and second body and the reciprocating drive-unit.

A dual-impeller spreader capable of independently a flowrate of particulate material about two halves of the spreader's coverage area. The spreader includes a frame, a hopper, and wheels rotatably connected to the frame via an axle. A first impeller is fixed to a first impeller shaft rotatably coupled to the axle via a first gear train, and a second impeller is fixed to a second impeller shaft rotatably coupled to the axle via a second gear train. A first shut-off control selectively opens and closes a first set of hopper exit openings located above the first impeller, while a second shut-off control selectively opens and closes a second set of hopper exit openings located above the second impeller. The first shut-off control and the second shut-off control selectively open and close the respective openings independent of each other.

In a spreading apparatus for scattering spreading material, in particular sand or soil substrates, onto a ground surface, includes a container for the spreading material and at least one spreading unit by which the spreading material in the container can be scattered, wherein the spreading unit includes at least one rotatable spreading disc which is substantially parallel to the ground and at least one drive device for rotating the spreading disc about the axis of rotation with the result that the spreading material can be scattered by the spreading disc and by virtue of centrifugal forces, provision is made for a limiting device to be arranged in at least part of the circumferential region of the spreading disc, which limiting device prevents the scattering of the spreading material in this part of the circumferential region, wherein the position of the limiting device relative to the spreading disc is adjustable, with the result that the direction in which the spreading material can be scattered is variable.

This skirt (20) is intended to equip a coating product rotary projector. The skirt (20) has a plurality of air ejection nozzles (40, 42, 44, 46) arranged in said skirt (20) to eject jets of air forming shaping air suitable for shaping the jets of coating product, said air ejection nozzles (40, 42, 44, 46) comprising at least three separate series of nozzles (41, 43, 45, 47) each made up of a plurality of air ejection nozzles (40, 42, 44, 46) fluidly connected to a shared supply chamber, specific to said series of nozzles (41, 43, 45, 47).

Disclosed herein is a method for assessing a shape of a bell-shaped liquid spray, including the steps of operating a spray nozzle for delivering a bell-shaped liquid spray and capturing an image of a plurality of liquid jets forming the delivered bell-shaped liquid spray during operation of the spray nozzle, and a computer program product for assessing a bell-shaped liquid spray.

A coating liquid mixing device includes a supply tube including flow paths through which respective coating liquids flow and which are distally open; and a mixing nozzle communicating with an outlet of the supply tube so that the coating liquids flowing through the flow paths are supplied to an interior space, and including a reduced diameter portion in which the interior space is reduced toward an outlet so that an open area of the mixing nozzle is smaller than a total open area of the flow paths.

A process for making multiparticulates, comprising providing a molten feed comprising an active ingredient and an excipient, and providing a spinning disc sprayer comprising a rotating disc having a feed-receiving surface driven from above by a hollow drive shaft, wherein axes of rotation of the hollow drive shaft and rotatable disc are coaxial and a downward end of the hollow drive shaft is disposed with a distributor for regulating flow of the molten feed into the well, the distributor and the well together configured for providing a substantially radial, uniform outward flow of the molten feed across the feed-receiving surface.

A dispensing nozzle and a dispensing assembly incorporating the dispensing nozzle are provided. The dispensing assembly comprises a cap body, a dispenser actuator, and a dispensing nozzle. The dispensing nozzle comprises a nozzle base having a mounting end configured to be mounted to the dispenser actuator; and a nozzle body connected, at a connection joint, to a distal end of the nozzle base. The connection joint includes a first surface having an arcuate slot and a second surface opposing the first surface, which may include a post, the arcuate slot being configured to receive the post. The post is configured to pass through the arcuate slot such that the nozzle body is configured to rotate about the nozzle base.

A speed retarding device for a rotary nozzle includes a hollow cylindrical housing and a rotatable tubular shaft rotatably carried by the housing. The shaft has a central axial bore and an enlarged drag sleeve portion carried in the housing. A pair of support bearings support the drag sleeve portion of the shaft in the housing. An annular inner seal between each of the support bearings and the drag sleeve portion defines a cavity within the housing receiving a viscous fluid confined within the cavity. The drag sleeve portion includes a peripheral helical groove and a plurality of axial bores extending therethrough parallel to the central bore, one or more blind axial bores each having a closed end an open end, and a piston disposed in each of the one or more blind axial bores each defining an air space between the closed end and the piston.
