Abstract:
A mist-generating device includes: a droplet generating unit that generates, in a third liquid, a functional droplet including a first liquid that is spherical and a second liquid that covers an entirety of the first liquid and has a volatility lower than a volatility of the first liquid; and a mist-generating unit that generates a multilayer mist obtained by atomizing the third liquid containing the functional droplet.
Abstract:
This disclosure provides an improved nozzle assembly. The nozzle assembly includes a spray element for jetting media through an outlet (e.g. onto a surface), an active conduit for supplying a first media to the spray element, and a passive conduit for supplying a feed of a second media to the spray element. The spray element includes an eductor that is actively fed with a pressurized stream of the first media (i.e., motive fluid) via an annular injection port coupled to the active conduit, and passively fed by the second media via an intake duct disposed cen-trally within the injection port. The eductor utilizes the Venturi effect to efficiently prepare a homogenized media jet from the two different media feeds. A system comprising the nozzle assembly, and methods of using each of the same, are also disclosed.
Abstract:
A method of applying a coating composition to a substrate utilizing a high transfer efficiency applicator include the steps of providing the high transfer efficiency applicator comprising an array of nozzles wherein each nozzle defines a nozzle orifice having a diameter of from 0.00002 m to 0.0004, providing the coating composition, and applying the coating composition to the substrate through the nozzle orifice without atomization such that at least 99.9% of the applied coating composition contacts the substrate to form a coating layer having a wet thickness of at least 5 microns, wherein the coating composition includes a carrier, a binder, and a radar reflective pigment or a LiDAR reflective pigment. The coating composition has an Ohnesorge number (Oh) of from about 0.01 to about 12.6, a Reynolds number (Re) of from about 0.02 to about 6,200, and a Deborah number (De) of from greater than 0 to about 1730.
Abstract:
The present invention relates to a method and apparatus for delivering droplets of fluids onto an open tray containing poultry, the tray being stationary. According to the invention, the method comprises the following steps: (a) a movable arm is moved over the tray in translation in a first direction, said arm supporting a first set of dispensing nozzles and a second set of dispensing nozzles, said nozzles of each set being arranged to cover the entire dimension of the tray in a second direction perpendicular to the first direction; (b) initially, droplets of at least one first fluid are dispensed by spraying using the first set of dispensing nozzles; (c) and then at least one second fluid, distinct from said at least one first fluid to be sprayed, is dispensed by ejecting individual drops by means of the second set of dispensing nozzles.
Abstract:
The invention relates to an applicator connection unit for an application robot for coating objects having supply lines for an applicator. An applicator can be fastened on the applicator connection unit in such a way that working lines of the applicator are connected to the supply lines of the applicator connection unit. The applicator connection unit is formed as an adapter unit in such a way that at least one applicator of a first mode of operation and one applicator of a second mode of operation can be releasably and replaceably fastened to the applicator connection unit. The invention further relates to an application robot and a system for coating objects, wherein such an applicator connection unit is used.
Abstract:
A needle assembly may include a needle, a packing assembly that surrounds a first portion of the needle, and an actuatable adjustment element coupled to the packing assembly that changes a relationship between the needle and the packing assembly when actuated. The needle assembly may also include a base assembly that has a collar section and an elongated section. The elongated section includes a bore surrounding a second portion of the needle. The bore may terminate within the elongated section and before the collar section. The elongated section may be coupled to the second portion of the needle via an interference fit.
Abstract:
The present technique provides a system and for improving control of a needle valve in a spray coating device. An exemplary spray coating device of the present technique has a needle valve assembly that controls entry of a fluid to a fluid delivery tip. The needle valve assembly includes an adjustment element that is at least partially located on an exterior of the spray coating device such that the adjustment element is accessible by an operator. The adjustment element may be actuated to improve a seal around the needle so that fluid does not leak from around the needle valve assembly.
Abstract:
Described is a method of supplying an active ingredient to a location beneath the outer layer of skin or into soft tissue which includes the steps of providing a polymer-containing liquid comprising an active ingredient; subjecting the liquid issuing from an outlet to an electric field to cause the liquid to form at least one electrically charged jet that breaks up to provide charged fiber fragments or fibrils containing an active ingredient, the fiber fragments or fibrils being capable of sticking onto the outer layer of skin or soft tissue to supply the active ingredient beneath the outer layer of skin or soft tissue; and contacting skin with the fiber fragments or fibrils.
Abstract:
A decoration method and system, suitable for decorating, with a decorator unit, multiform ceramic products having multiform surfaces to be decorated, includes moving the multiform products and/or the decorator unit relative to each other with a movement device such that the decorator unit follows the multiform surfaces to be decorated. Decorating substances are dispensed with a dispensing device, which is moveable in space.
