In an aspect, a burner includes (a) a burner body and (b) at least one connector configured to supply at least a fuel and an oxidizer to the burner body. The burner body includes (1) a plurality of passageways; (2) a first major surface; (3) a plurality of ports at the first major surface, each port defined by an end of one of the passageways; and either: (4a) at least one heating element in or adjacent to at least one of the plurality of passageways that increases the temperature of a wall of the at least one of the plurality of passageways; or (4b) a cooling chamber directly adjacent to three or more of the plurality of passageways. The burner body includes a number of layers of metal directly bonded to each other. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying a burner body; and generating, with the manufacturing device by an additive manufacturing process, the burner body based on the digital object. A system is also provided, including a display that displays a 3D model of a burner body; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of the burner body.

Burners and additive manufacturing methods

Also methods for making such films and articles comprising such films.

Hand tearable sheets and method for manufacturing same

A coating composition is disclosed. The coating composition includes a poly(methyl methacrylate) polymer or copolymer having a weight average molecular weight of at least 50,000 grams per mole; monomer comprising at least one of an alkylene diacrylate, alkylene dimethacrylate, cycloalkylene diacrylate, or cycloalkylenedimethacrylate, wherein the at least one of an alkylene diacrylate, alkylene dimethacrylate, cycloalkylene diacrylate, or cycloalkylenedimethacrylate provides at least 80 percent by weight of the monomer; and a stabilizer against ultraviolet light. An article including a coating on a surface of a substrate and a method of making the article are also disclosed. The coating on the surface of the substrate is obtained by curing the disclosed coating composition.

Polymethylmethacrylate based hardcoat composition and coated article

Material comprising sub-micrometer particles dispersed in a polymeric matrix. The materials are useful in article, for example, for numerous applications including display applications (e.g., liquid crystal displays (LCD), light emitting diode (LED) displays, or plasma displays); light extraction; electromagnetic interference (EMI) shielding, ophthalmic lenses; face shielding lenses or films; window films; antireflection for construction applications; and construction applications or traffic signs.

A protective film includes a base layer and a wear layer, the wear layer comprising a UV cured hardcoat resin, and the UV cured hardcoat resin comprising surface modified silica nanoparticles. The protective film may comprise a pressure sensitive adhesive for adhesion to a floor. The protective film may be used, for example, as a protective floor finish.

Protective films and related methods

A method for forming an inorganic or hybrid organic/inorganic layer on a substrate, which method comprises applying a metal alkoxide to form a layer atop the substrate and exposing the metal alkoxide layer to heat from a catalytic combustion heater in the presence of water to cure the layer is provided.

Method of curing metal alkoxide-containing films

An apparatus and methods for flame-perforating films. A preferred embodiment of the apparatus includes a frame, support surface attached to the frame, where the support surface includes a plurality of lowered portions, a burner attached to the frame opposite the support surface, where the burner supports a flame, and where the flame includes a flame tip opposite the burner and a film contacting the support surface, where the flame of the burner is in contact with the film, where the burner is positioned such that the distance between an unimpinged flame tip of the flame and the burner is at least one-third greater than the distance between the film and the burner.

Methods for flame-perforating films

Disclosure is made of methods, systems, and apparatus for changing characteristics of noise of premixed flames supported on burners by heating burner passageways by an amount that attenuates combustion noises arising from premixed flames. Alternatively, attenuation occurs by controlling a temperature differential between a first point relative to a premixed flame and at least a second point in an uncombusted portion of a fuel/oxidizer mixture causing the flame

Attenuating combustion noise of premixed flames

The present invention provides an apparatus and methods for flame-perforating polymeric films with an oxygen-enriched flame. One embodiment of the apparatus includes a frame, a support surface attached to the frame, where the support surface includes a plurality of lowered portions, an oxygen-enrichment system for increasing the amount of oxygen in the combustible mixture, a burner attached to the frame opposite the support surface, where the burner supports a stable flame, and a film contacting the support surface, where the flame of the burner is directed towards the film to cause the film to be perforated. One embodiment of the method of flame perforating a polymeric film includes igniting an oxygen-enriched combustible mixture to form a stable flame, wherein the flame generated by the oxygen-enriched combustible mixture provides more uniform perforations.

Methods and apparatus for oxygen enriched flame-perforation of a polymer film

Methods and systems utilize an atmospheric-pressure nitrogen dielectric-barrier discharge to treat the surface of polymer substances. The atmospheric-pressure nitrogen dielectric-discharge may be maintained with a level of HO below a pre-defined amount, such as by measuring and controlling the HO within a treater, to produce a surface treatment for a polymer substance that yields desirable characteristics. Furthermore, the HO level may be measured and controlled according to a pre-defined amount or according to another parameter such as an analysis of the resulting polymer surface. For example, the polymer surface may be provided with an optimal added nitrogen-to-added oxygen ratio and/or an optimal stability based on washed and unwashed advancing contact angles such as by controlling the HO level within the treater based on these analyses of the treated polymer.
