A method of applying heat shield material to form a heat shield layer on a crown surface of a piston of an engine is provided. The method includes the steps of disposing a dispenser that linearly discharges the heat shield material toward the crown surface, and moving an applied position of the heat shield material with respect to the crown surface in a circumferential direction of the crown surface, while discharging the heat shield material from the dispenser toward the crown surface.

A substrate processing apparatus includes a substrate holder, a processing liquid supply and a cover unit. The substrate holder holds a substrate horizontally and rotate the substrate. The processing liquid supply supplies a processing liquid toward a first surface of the substrate held by the substrate holder. The cover unit faces a second surface of the substrate, the second surface being opposite to the first surface. The cover unit includes a heater configured to heat the substrate. The cover unit is provided with an opening at a position corresponding to a central portion of the substrate and multiple gas supply openings, at an outer peripheral side than the opening, through which a gas is supplied toward the second surface of the substrate. The gas is heated by the heater. A supply amount of at least some of the gas is adjusted based on a rotation speed of the substrate.

The present disclosure relates to a manufacturing process of a silicone glove, the silicon glove is divided into a liner, a glove blank and a silicon layer from the inside to the outside, and liquid silicon is sprayed on a surface of the glove blank for once; when spraying the liquid silicon, the glove blank also rotates around its axis while horizontally moving on an assembly line; during spraying, a liquid silicon outflow channel at least includes a finger gap spraying port and a tiger mouth spraying port that are arranged fixedly; an arranging length of the finger gap spraying port is greater than or equal to a length of a finger area of the glove blank; an arranging length of the tiger mouth spraying port is greater than or equal to a length of a tiger mouth area of the glove blank.

A method of applying an air barrier material to an inner surface of a tire includes steps of: (a) performing a post-cure inflation of the tire; (b) placing the tire onto a dump gate platform after finishing the post-cure inflation of the tire; and (c) spraying the air barrier material onto the inner surface of the tire while the tire is on the dump gate platform.

A device for depositing paste patterns on the surface of the channel of a tube, the device comprising a frame supporting a first mechanical assembly for holding, positioning and moving the tube, and a second mechanical assembly for extruding paste for depositing said paste patterns, the assemblies cooperating with one another.

An assembly for decorating a plurality of objects, such as egg-shaped objects. The assembly has a support structure; a vessel for containing decorating material, with an dispensing opening at the bottom; a tether with a first tether end attached to the support structure and a second tether end attached to the vessel; and a substrate base for supporting the plurality of objects. The vessel is configured to swing freely over the objects on the substrate base to dispense the decorating material contained therein to the objects.

A method of coating a structure is disclosed. Method steps include providing a structure having a first portion of a first material having a first surface and providing a second portion of a second material having a second surface, wherein a mask is provided over the first surface. Another step includes exposing the mask and the second surface to a solution comprising a polymer and a solvent, wherein the solution dewets from the mask and the polymer collects onto the second surface to form a polymer coating over the second surface without forming a polymer coating on the first surface.

A post-cure inflation machine for processing a tire may include a tire holder shaft. The tire holder shaft may include a chuck to secure the tire to the tire holder shaft. A hollow passage may be defined in the tire holder shaft. A spray nozzle may be connected to a spray shaft that is telescopically disposed in the hollow passage of the tire holder shaft. The spray nozzle may extend to spray an air barrier material onto the tire.

A mechanism for applying a predetermined pattern of material onto an elongate tubular substrate includes a first motor, an engagement member rotatable by the first motor and configured to reversibly grasp an elongate member, such that rotation of the first motor rotates the elongate member around its longitudinal axis, a fluid dispenser configured to dispense a fluid having a first, flowable state, the fluid dispenser including an elongate dispensing conduit having a distal end having an orifice, the orifice configured to be placed adjacent a surface of the elongate member, a second motor configured to move at least one of the elongate member or the elongate dispensing conduit such that the orifice changes its relative orientation along the longitudinal axis of the elongate member, and wherein the distal end of the elongate dispensing conduit is configured to apply a bias on the surface of the elongate member.

Methods of producing an additive manufactured part with a smooth surface finish and customized properties include creating a compensated design that serves as a print recipe for an additive manufacturing process for a part, where the creating comprises modifying a desired design with a geometric offset correction to compensate for a first portion of an uncured surface finish material to be retained on the part. A spinning device is provided that has a platform. The part is formed with the additive manufacturing process and secured to the platform, where the part is at least partially wetted with the uncured surface finish material. The platform is rotated, where a second portion of the uncured surface finish material is removed due to forces imparted by the rotating. The uncured surface finish material is chosen to customize a property of the part.
