Abstract:
The rotary atomizing painting device is provided with a bell cup (3) disposed at the most front part in the paint spray direction X and axially supported by a rotating shaft (2b) and a shaping air ring (4) disposed rearward of this bell cup (3) in the paint spray direction and in which a plurality of discharge openings (4a) is formed on the periphery centered on the rotating shaft (2b). The plurality of discharge openings (4a) is formed such that the axial direction of the plurality of discharge openings (4a) is in a direction and a slant to the rotating shaft (2b). The axial direction of the plurality of discharge openings (4a) is formed to aim at a back surface part (3b), which is a part on the back surface side of the bell cup (3) from the paint spray direction.
Abstract:
A liquid ejection apparatus comprising a fluid line configured to extend into a tank and to receive a liquid, a rotary head being arranged on the pipe and fitted with a rotary hub that comprises a liquid ejection nozzle for ejecting the liquid, the rotary head being rotatable in a first direction and the rotary hub being rotatable in a second direction, such that the liquid ejected by the nozzle is ejected in a pattern on an interior surface of the tank. The liquid ejection nozzle comprises a first liquid outlet capable of ejecting the liquid in a first direction towards the interior surface of the tank, and a second liquid outlet capable of ejecting the liquid in a second direction towards the interior surface of the tank.
Abstract:
The invention relates to a droplet break up device (1) comprising: a chamber (2) for containing a pressurized printing liquid (3) comprising a bottom plate; at least one outlet channel (4, 4′) having a central axis, provided in said chamber for ejecting the printing liquid; and an actuator for breaking up, a fluid jetted out of the outlet channel. The actuator comprises a revolving, member (5) comprising a surface deformation (7, 7′) shaped to provide a pressure pulse near the outlet channel. Accordingly, a simple mechanism is provided for providing multiple printing nozzles.

Abstract:
A rotary atomizing head enables cleaning by decomposing from the atomizing head, and enables internal cleaning without decomposing to individual components when paint is changed to a new one of another color. A structural component has a front wall acting as a hub, side wall extending rearward from an outer circumferential perimeter of the front wall to make a circumferentially continuous plane, legs each having a pawl and a bottom wall. The structural component is detachably mounted in a central concavity of an atomizing head body. A bottom wall of the structural component has formed a spoon-cut recess. The central concavity has an inclined circumferential wall, and the side wall of the structural component has an inclined outer circumferential surface complementary with the circumferential wall of the atomizing head body to get in substantial contact with the circumferential wall throughout the entire area of the outer circumferential wall.
Abstract:
An etching device is disclosed. The etching device comprises a base; a receiving member mounted on the base, the receiving member defines a receiving hole to receive an etching solution, the receiving member comprises a side surface, the side surface defines at least one spraying hole interconnected with the receiving hole, and at least one spraying hole is adapted to spray the etching solution; and at least one rotating member rotatably mounted on the base, opposite to the side surface of the receiving member.
Abstract:
A spray head for spraying mortar is provided. The spray head includes a spinning head positioned at an outlet point of a mortar supply pipe, the spinning head directing mortar supplied from the mortar supply pipe in a direction substantially perpendicular to the direction of travel of mortar in the mortar supply pipe. The spray head further includes an air intake for receiving air, the air being employed to spin the spinning head pneumatically, and a material input port provided coaxial to the mortar supply pipe and around the mortar supply pipe, the material input port for providing material to be combined with the mortar in the mortar supply pipe at the outlet point of the mortar supply pipe.
Abstract:

Abstract:
The invention relates to a process for production of composite elements composed of at least one outer layer a) and of an rigid isocyanate-based foam b), where between the outer layer a) and the rigid isocyanate-based foam b) an adhesion promoter c) has been applied, and where the outer layer a) is continuously moved and the adhesion promoter c) and the starting material for the rigid isocyanate-based foam b) are applied successively to the outer layer, which comprises applying the adhesion promoter c) by means of a rotating plate which has been installed horizontally or with a deviation of up to 15° from horizontal, preferably parallel to the outer layer.
Abstract:
An atomizer for coating materials is provided. The atomizer includes two opposing discs connected by a central hub. Each disc includes an inwardly extending flange about its perimeter. The central hub has an exterior surface defining a v-shaped surface. When assembled in a coating apparatus, a fluid material, such as batter, may be dispensed toward the exterior surface of the hub while the disc is spinning. The resulting spray of fluid may be used to coat material effectively, while minimizing waste.
