Abstract:
A method of applying a corrosion-resistant coating to a fastener that includes preheating an area of the fastener to be coated to elevate a temperature of the area and spraying the preheated area of the fastener with a molten or semi-molten metal. In one embodiment, a corrosion-resistant coating applicator includes a support structure, a rotatable slotted fastener conveyer supported by the support structure, a feeder configured to feed fasteners to the rotatable slotted fastener conveyer, a fastener aligner configured to make head portions of the fasteners aligned with each other, a heater configured to heat head portions of the fasteners as the fasteners are being conveyed by the slotted fastener conveyer, and a sprayer configured to apply a corrosion-resistant coating to the heated head portions of the fasteners being conveyed by the slotted fastener conveyer. The present disclosure also provides corrosion-resistant coated fasteners made using the coating methods and/or coating apparatus.
Abstract:
Provided herein is a device for forming a conductive film. The device includes a deposition device and an air supply. The deposition device is configured to form a wet film having conductive nanostructures and a fluid carrier on a web. The web is moved in a first direction while forming the wet film. The air supply is disposed at a side of the web and configured to apply an air flow onto the wet film. The air flow is directed onto the wet film in a second direction perpendicular to the first direction to reorient a direction of some conductive nanostructures in the wet film to define reoriented conductive nanostructures.
Abstract:
An apparatus for controlling deposition of material from a plasma transferred wire arc (PTWA) torch within a bore is provided. The apparatus includes a duct and a plurality of cannons. The duct includes a plurality of fluid passageways separated by cross-members. The plurality of cannons are disposed adjacent and downstream from the plurality of fluid passageways of the duct. The flow of fluid is simultaneously directed through all of the fluid passageways and the plurality of cannons and past the PTWA torch in the bore.
Abstract:
The invention relates to a device and a method for hot-dip coating a metal strip with a metal covering, wherein the metal strip is directed continuously through a melt bath, wherein the thickness of the metal covering present on the metal strip when it leaves the melt bath is adjusted by means of a scraping device, and wherein slag which is present on the melt bath is driven away from the metal strip leaving the melt bath by means of a gas flow. To prevent slag from coming into contact with the metal strip leaving the melt bath, the invention drives away the slag from the metal strip by means of at least one nozzle which is arranged in close proximity to the metal strip, that a gas flow which extends over the width of the metal strip is directed onto the surface of the melt bath.
Abstract:
A device for producing a coated steel sheet includes: a blowing-off unit which sprays a gas onto and remove an excessive coating that accumulates along a side edge of a steel sheet that threads along one direction; and a coating-collection unit which collects the excessive coating removed by the blowing-off unit. The blowing-off unit includes a spray nozzle and a gas supply member. The coating-collection unit includes a duct and a coating container. In a case where the duct is seen in a plan view, an outlet thereof is disposed to fit in and overlap an inside of an opening of the coating container, and in a case where the duct is seen in a side view, a gap is provided between the outlet and the opening of the coating container.
Abstract:
The present invention provides a scattered powder cleaning device, comprising: a case having an exit formed at one side for the access of glass and an internal space; an opening and closing part for opening or closing the exit; a powder spray part provided to the case for spraying a predetermined amount of power at the internal space; and a cleaning part which forcibly scatters the powder dispersed at the internal space by forcibly introducing external air so as to discharge the powder to the outside if the glass escapes from the internal space.
Abstract:
In an indirect process, acrylic adhesive is coated on a silicone liner. A soft rubber roller is employed between a reverse anilox cylinder and an anvil cylinder in a flexo print station to reduce shear hardening in the coating process and prevent or reduce shear hardening on the print rollers. Once the coated silicone liner passes the rollers, air knives are used to speed up the drying of the adhesive on the silicone liner before the coated liner is laminated to a face stock.
Abstract:
Provided is a gas wiping device having a box-shaped body which encloses a steel band and gas wiping nozzles, wherein it is possible to prevent splash on the steel band. A gas wiping device provided with a plating bath for storing molten metal, and a box-shaped body placed above the plating bath. The box-shaped body is provided, in the interior, with tubular members disposed along the width direction of a band-shaped body, gas wiping nozzles disposed facing one another on the respective tubular members so as to sandwich the band-shaped body, extending members disposed on both ends of gas wiping nozzle so as to extend towards the direction of gas wiping nozzle, and extending members disposed on both ends of gas wiping nozzle so as to extend towards the direction of gas wiping nozzle.
Abstract:
An apparatus that uses an optimized body design incorporating one or more interchangeable nozzle inserts with a wide array of discharge orifice sizes, configurations and spacings to efficiently and effectively deliver a pressurized, high velocity, laminar flow air stream to dry, cool, or clean objects that are either stationary or moving transversely through the optimized air stream developed by the apparatus, all while minimizing the operational downtime required to implement the interchangeable nozzle insert modifications to the apparatus.
