Abstract:
A system for spraying and a method for making same. The system for spraying may comprises a sprayer having a sprayer body comprising a spray fluid passageway extending longitudinally through the sprayer body. The sprayer may also have a spray fluid inlet fitting to enable a hose operable to convey a spray fluid to be coupled to the sprayer body. In addition, the sprayer may also have a first air fitting to enable a first hose operable to convey pressurized air to be coupled to the sprayer body to trigger the sprayer to spray the spray fluid. The sprayer may have a second air fitting to enable a second hose operable to convey pressurized be coupled to the sprayer body to atomize the spray fluid. The spray fluid inlet fitting, the first air fitting, and the second air fitting are angled at an acute angle relative to the spray fluid passageway extending longitudinally through the sprayer body.
Abstract:
The organic raw material is vaporized to generate the raw material gas in the vaporizing chamber. This raw material gas is mixed with the carrier gas, and transported to the chamber through the raw material gas transportation pipe. The substrate is held within the chamber while the organic film formation surface of the substrate does not face downward in a vertical direction straight up from the ground. The injector of the raw material gas is opposed to the substrate. The raw material gas is blasted from the direction orthogonal to the substrate. Particles fall without adhering to the substrate when holding the substrate in the vertical direction. The deformation of the substrate and the mask for separately painting pixels can be suppressed.
Abstract:
An external mixing nozzle, with a flat-jet cap which is fastened to a nozzle body, the flat-jet cap being provided with a central bore or the like, pointing towards the nozzle body, for receiving a liquid insert, and having a central orifice which receives a mouth attachment of the liquid insert, at the same time defining an annular gap surrounding the mouth attachment, the flat-jet cap defining a planar surface portion which runs perpendicularly to the axis of the nozzle body and within which a central orifice is provided, and, furthermore, the surface portion having adjoining it laterally two surfaces running essentially mirror-symmetrically and obliquely to the axis of the nozzle body and adjoining the surface portion, wherein the flat-jet cap contains, in the region of the surface portion, outlet orifices which are provided at an equal distance from the central orifice and which communicate with bores provided so as to run in the jet cap obliquely to the axis of the nozzle body, with transitions from the surface portion to the lateral surfaces being defined by smooth transitions or roundings.
Abstract:
An improved spray through cap assembly (10) comprises separable base (11) and cover parts (13). The base part includes a hollow actuator (17) which is adapted to cooperate with an outlet of an aerosol or the like. The actuator is linked to a fluid flow channel (19) formed by correspond recesses in the base and cover parts respectively and a nozzle outlet (20). Depressing the cover part causes the actuator to actuate the outlet and causes the contents of the aerosol to be discharged through the nozzle outlet via the fluid flow channel. In order prevent accidental discharge, in one embodiment, the base part includes a projecting lip (22) and the cover part includes a nose (21), the lip and nose cooperating in an inoperative position to prevent the actuator actuating the outlet. In a further embodiment, the cover part is formed from two separable parts and the fluid flow channel and nozzle outlet are formed by corresponding recesses in the parts of the cover parts. In this embodiment, the cover part and base part can be separated prior to separating the respective parts of the cover part for cleaning thereby also preventing accidental discharge on cleaning.
Abstract:
A liquid crystal dispensing apparatus dispenses liquid crystal onto a substrate. The apparatus includes a liquid crystal container and a nozzle. The liquid crystal container contains the liquid crystal to be dispensed onto the substrate, and the nozzle is disposed on a lower portion of the liquid crystal container. The nozzle has a main body portion, a discharging portion that projects from a lower surface of the main body portion to dispense liquid crystal, and a protecting portion that projects from the lower surface of the main body portion to protect the dispensing portion. The protecting portion projects from the lower surface of the main body portion at least as much as the discharging portion.
Abstract:
An apparatus and method for droplet steering is disclosed herein. A throated structure having a nozzle defines a converging throat with an inlet and an outlet and a vectored fluid stream directed therethrough. The fluid stream is driven through the system via a vacuum pump. As the fluid approaches the outlet, its velocity increases and is drawn away from the nozzle through a connecting channel. As a droplet is ejected from a liquid therebelow, it will have a first trajectory until it is introduced to the high velocity fluid stream at the perimeter of the interior walls of the nozzle. The fluid accordingly steers the momentum of the droplet such that it obtains a second or corrected trajectory. Alternative variations include an electrically chargeable member, e.g., a pin, positionable to be in apposition to the outlet and capillary tubes for controlling the ejection surface of the pool of source fluid.
Abstract:
In a powder atomizer for series coating of workpieces, additional air is led from a separate channel into the path of the powder-air mixture which exits from the powder channel of the atomizer, air which can be used during the coating to influence and change the mixture and, during pauses in the coating, as rinsing air for cleaning, for example, the powder path leading through an atomization bell.
Abstract:
A coating-powder spray gun comprising a gun housing (2) of which the front end face is sealed pressure-hermetically with respect to compressed gas by a front end wall (28). A current-limiting resistor (32) and at least a portion of a high-voltage generator (10) are potted in an integral electrically insulating block. The potted block may be received in the gun housing (2).
Abstract:
A firefighting nozzle capable of selectively producing only a solid stream, only a fog pattern or a combination of both. The passage for the fog liquid can be opened to a flushing position for flushing debris therefrom. A solid stream sleeve is removably attached to a nozzle body for allowing discharge of solid streams having different diameters. A valve ball having primary and secondary flow passages is movable to positions for supplying liquid therethrough to both solid stream and annular fog supply passages, or to only the annular fog supply passage while closing the solid stream passage.
Abstract:
The present invention relates to air-assisted, low pressure spray equipment having an improved spray nozzle including a) a caulking gun having a carriage adapted to receive two or more cartridges having a nozzle, two or more rams mounted on the caulking gun for operatively engaging each cartridge to dispense a liquid component from the nozzle of the cartridge, a trigger mechanism for manually, pneumatically, hydraulically or electrically advancing the rams incrementally into operative engagement with each cartridge, b) a static mixer having an inlet port on its upstream end for receiving a liquid component from the nozzle of each cartridge and having on its downstream end an optionally removable spray tip for introducing the mixed liquid components into an atomizing zone, c) a static mixer shroud, which encases the static mixer, is dimensioned on its upstream end for connecting the shroud to the cartridges of the caulking gun and has on its downstream end an optionally removable spray section having inlet ports for receiving pressurized air and outlet ports for introducing air into the atomizing zone, wherein the spray tip passes through an orifice in the spray section such that the mixed liquid components are introduced into the atomizing zone. The present invention also relates to a process for spraying a two-component composition with the air-assisted, low-pressure spray equipment.
