Abstract:
A method for preliminary treatment of particles of a powder in a dry surface treatment process before applying the powder particles on a surface of a substrate by utilizing an electric field created by electrodes. The Electrodes are located at opposite sides of the substrate in such a way that at least one first electrode is located at the side of the substrate to be coated, and at least one second electrode is located at the opposites side of the substrate. The particles of the powder are pre-charged before bringing them into the electric field.

A method of forming a color filter is provided. The method includes providing a mixture of a color filter material and a compressed fluid; providing at least a partially controlled environment for retaining a substrate, the at least partially controlled environment being in fluid communication with the mixture of the color filter material and the compressed fluid; providing a shadow mask in close proximity to the substrate retained in the at least partially controlled environment; and chargably releasing the mixture of the color filter material and the compressed fluid into the at least partially controlled environment, wherein the color filter material becomes free of the compressed fluid prior to contacting the substrate at locations defined by the shadow mask thereby forming a patterned deposition on the substrate.
Abstract:
The present invention is a method for zinc plating a meter set assembly used in gas delivery applications, wherein a zinc plating is applied to a steel substrate formed in the configuration of a meter bar. Once the zinc plating is applied through electrodeposition, the meter set assembly is then outgassed in an oven as by curing at 425°-475° F. for 20-35 minutes to drive away any gasses that may be trapped within the zinc coating. Following the outgassing process, a polyester powder coating is applied to the external surfaces of the meter bar.

Abstract:
A method for establishing a calibrating standard for wafer inspection includes depositing solid ionized particles of a known size range with an aerosol onto a wafer. The method also includes depositing particles onto a wafer in a deposition chamber by using an aerosol stream and the solid particles suspended in a gas; ionizing the aerosol stream with a negative or positive charge polarity or both by passing the aerosol stream through a non-radioactive ionizer to produce charged particles and supplying such aerosol stream to the deposition chamber. An apparatus for producing charged particles includes an atomizer and a non-radioactive ionizer in fluid communication with each other. The apparatus may also include an electrospray droplet generator for producing an aerosol with dry-solid particles and an ionizer that ionizes the molecules of the gas. The apparatus may also include a generator for generating an aerosol with particles suspended in the gas with a non-radioactive ionizer that ionizes the gas in the aerosol causing the aerosol particles to be charged. The apparatus may further include an electrostatic classifier for classifying the charged particles to a selected size range.
Abstract:
An apparatus and method for locking a gun. The apparatus includes a dummy round configured for insertion into a firing chamber of a gun, a locking component configured for coupling with the dummy round, and an elongated sleeve rotatably coupled with the locking component. The locking component includes a keyed head positioned within a longitudinal channel of the elongated sleeve. The locking component and elongated sleeve are insertable through the discharge end of a gun's barrel. An actuating mechanism, such as a key is insertable through the channel of the elongated sleeve to engage with the keyed head and rotate the locking mechanism relative to the elongated sleeve. Rotation of the locking mechanism effects a friction lock between the locking mechanism and the dummy round.
Abstract:
The present invention provides a powder paint excellent in productivity and cost, because the powder paints that are not adhered to the substrate can recovered and reused. And in case of using the powder paint of the present invention, coating efficiency is high and fine textured coated films excellent in attractiveness of appearance and water resistance can be obtained, because the base paint powder and the pigment particle thereof hardly separate. The powder paints of the present invention are characterized in that the pigment particles are bound to the base paint powders via shellac. The powder paints of the present invention not only allows uniform and firm binding of pigment particles to base paint powders by the action of shellac, but also provides the resulting coated films with excellent attractiveness of appearance.
Abstract:
A system for electrostatic powder coating irregular shaped, three-dimensional articles with 10 μm average diameter powder particles. A supply of powder particles are triboelectrically charged and transported onto one or more donor rolls without the need from fluidization of the powder particles. The charged powder particles on the one or more donor rolls are metered to provide a uniform layer thereon. A combination of AC electric fields and/or air jet detach the powder particles from the one or more donor rolls and produce a powder cloud that is directed to the grounded article to be coated. A layer of powder particles coats the outer surface of the article, and the layer is subsequently cured to form a permanent and durable film on the article.
