The invention relates to a new method for the formulation of oily substances, and to powders and solid dosage forms obtainable thereof. The process comprises a step of spray-drying of an oil-in-water emulsion comprising an octenyl succinate starch and a maltodextrin.

A process for coating a gas turbine engine component is disclosed herein. The process comprises applying a bond coat on a substrate of a gas turbine engine. A thermal barrier material is applied to the bond coat. A coating containing polynuclear aluminum oxide/hydroxide clusters is then applied to the thermal barrier material. The polynuclear aluminum oxide/hydroxide clusters are Al.sub.13 Keggin clusters having the formula [AlO.sub.4Al.sub.12(OH).sub.24(H.sub.2O).sub.12].sup.7+, or are salts of the Al.sub.13 Keggin clusters called Al.sub.13 Keggin complexes. A gas turbine engine component comprising a superalloy substrate; a bond coat disposed on the substrate; a thermal barrier material on the bond coat; and a coating containing the polynuclear aluminum oxide/hydroxide clusters on the thermal barrier material is disclosed herein.

Disclosed are a coating apparatus and a coating method. The coating apparatus includes a chamber, a support located in an interior space of the chamber and configured to support a substrate which is to be coated, an ejection nozzle configured to eject a coating material toward the support, and an electric field forming unit configured to form an electric field in a movement path of the coating material to provide kinetic energy for the coating material.

An example system includes an additive manufacturing tool configured to receive a wire from a wire feeder, to receive current from a power source, and to supply the wire to a workpiece during an additive manufacturing process, and a mechanical oscillation system configured to mechanically oscillate a structural component toward and away from the workpiece, wherein the structural component is external to the wire feeder and the power source.

The present invention relates to a portable spay device and, more specifically, to a portable spray device moving a cartridge member by means of a simple rotational motion of a spray rotating body, thereby enabling powder positioned inside the cartridge member to be effectively sprayed to the outside.

A film forming device 10 including a distance measurement unit 30 for measuring the distance between the skin S and the device 10, a distance decision unit 31 for deciding whether the distance measured by the distance measurement unit 30 is proper for electrostatic spraying, and a distance notification unit 32 for notifying a user of the decision by the distance decision unit 31. The film forming device 10 is of hand-held type small enough and configured to be held by the user's hand. The device 10 preferably includes an angle measurement unit 42 for measuring the angle between the electrostatic spray direction and the skin S.

Embodiments relate to a system for manufacturing nano-scale energy harvesters and electric power generators. The system includes a plurality of dispensers to dispense a first material, a second material, and a separation material between the first and second materials. The first material has a first work function value and the second material has a second work function value different from the first work function value. At least one electrospray device is positioned proximal to the third dispenser to deposit a fluid within at least a portion of the separation material. The fluid has particles with a third work function value different from the first and second work function values. The system also includes a guide assembly to transport the first and second electrodes, the positioned separation material, and the fluid to a joint proximal position and form a fabricated product.

A motor includes: a motor housing; a shaft disposed inside the motor housing and extending along a rotation axis; a rotor having magnetism, and coupled to an outer circumferential surface of the shaft; a stator accommodated in the motor housing, disposed to be spaced apart from an outside of the rotor in a radial direction of the shaft, and wound around with a coil; a nozzle for charging a cooling fluid by applying a voltage, and spraying the cooling fluid to at least one of the rotor and the stator; and a charging plate disposed to be spaced apart from a spray hole of the nozzle, and changes a spray form of the cooling fluid by applying a voltage.

An electrostatic sprayer system for dispensing and dispersing a liquid containing a spray compound includes a spray cloud dispersal feature that reduces the time that a residual spray cloud containing droplets including the spray compound remains suspended after spraying. A method of dispersing the residual spray cloud is implemented by a control system that causes a flow control system to deliver a non-active gas or liquid in conjunction with stopping delivery of the liquid containing the spray agent and charged with the same polarity, so that a charged cloud of the non-active gas or liquid, which may be air, displaces the suspended active fluid particles. The non-active gas or liquid may be dispensed for a predetermined time interval as determined by the control system, or the operator may control the time interval during which that the non-active fluid is dispensed.

An additive manufacturing system includes an additive manufacturing tool configured to supply a plurality of droplets to a part, a temperature control device configured to control a temperature of the part, and a controller configured to control the composition, formation, and application of each droplet to the plurality of droplets to the part independent from control of the temperature of the part via the temperature control device. The plurality of droplets is configured to build up the part. Each droplet of the plurality of droplets includes at least one metallic anchoring material.
