Disclosed is a method of using laser sensors to measure the top surface of the granular flux powder height at the top of the continuous caster. Additionally, the laser sensor measures the height of the underlying sintered or liquid flux level absent the powder. This disclosure includes a method of utilizing a laser sensor and a gas puff to determine both the granular powder depth and the level of the underlying solid or liquid layer. The granular powder depth measurement then is utilized in a mold powder deposition system to permit feedback control so as to maintain the granular powder thickness.

A method of bonding a nanofiber web of nanofibers having diameters of between about 50 nanometers and about 2,000 nanometers onto a surface of a woven or nonwoven polymeric media having media fiber diameters of between about 700 nanometers and about 50,000 nanometers utilizes exposing the topmost layer of nanofibers and media fibers to a jet of heated air for a time and at a distance such that substantially only the topmost layer of fibers are bonded. The jet of heated air exits through a nozzle slot having a length of less than about 2 inches in the nanofiber web travel direction. The temperature of the heated air ranges from about 2 to about 10 times the nanofiber melting temperature, and heat air has a nozzle slot velocity of greater than about 500 feet/minute. An adhesive may bond the nanofibers, to a media, which may be bi-component fiber fibers.

A method comprises introducing a fluid composition into one or more electrically insulating emitters, and applying voltage to the fluid to cause ejection of the solvent from the fluid after it exits the emitter. The fluid composition comprises first material having a dielectric constant greater than &#x2dc;25 and polymer mixed into liquid solvent having a dielectric constant less than &#x2dc;15, or polymer mixed into solvent having a dielectric constant greater than &#x2dc;8. Voltage can be applied to the fluid composition via a conductive electrode immersed in the fluid, or positioned outside and adjacent to the emitters. Conductivity of the fluid composition can be less than &#x2dc;100 &#x3bc;S/cm. A composition of matter comprises nanofibers formed by the method.

Apparatus, methods, and fluid compositions for electrostatically-driven solvent ejection or particle formation

A first method comprises: dissolving a polymer in a terpene, terpenoid, or aromatic solvent to form a polymer solution; dissolving a salt in a polar organic solvent to form a salt solution; and mixing the salt solution and the polymer solution to form a mixture. The salt and the polar organic solvent do not cause substantial precipitation of the polymer upon mixing with the polymer solution. A resulting terpene, terpenoid, or aromatic solvent phase of the mixture is suitable for forming fibers by electric-field-driven spinning from one or more spinning tips onto a target substrate. A composition comprises the terpene, terpenoid, or aromatic solvent phase of the mixture resulting from the method. A second method comprises forming fibers by electric-field-driven spinning of the first composition from one or more spinning tips onto a target substrate. A second composition comprises the fibers formed by the second method.

An electrohydrodynamic spraying or spinning deposition system, which includes a common source of pressurized liquid within a manifold, and an array of 2 or more spraying tips, each tip being fed from the common source of pressurized liquid to create a liquid flow path. An individual flow impedance device is disposed within each tip's individual liquid flow path from the pressurized liquid source into each spraying tip. The individual flow impedance devices are disposed within a replaceable sheet, which can be easily cleaned or changed to accommodate the instance liquid viscosity and composition. A high voltage source is applied to create a high voltage potential applied between the tip array and a deposition surface.

A method for identifying dip-galvanized parts commences with marking a tag (e.g., metal) with identification indicia for a galvanizable part. The markings and the tag are resistant to molten zinc. A temporary film is applied over the identification indicia. The temporary film is resistant to pre-galvanizing treatment, but is removed (burned away) during dip galvanizing without obscuring the readability of the identification indicia. Finally, the metal tag is associated with the galvanizable part and the part galvanized in a molten zinc bath.

Identification method for dip galvanizing

A method for marking cold (e.g., about room temperature to 800&deg; F.) substrate (e.g., glass, ceramic, metal) commences by creating a tape of a carrier backing bearing a laser ablatable, non-tacky coating with optional barrier and release coatings between the carrier backing and the coating. The coating is laser ablated to form one or more of alphanumeric characters or graphics on the carrier backing. The ablated coating on the carrier backing is heated to form a tacky film of the coating on the carrier backing. The tacky film is roller transferred from the carrier backing onto a pliable transfer pad. Finally, the tacky film is roller transferred from the pliable transfer pad onto the cold substrate for its marking.

The present invention is directed to a system for marking objects for their identification which marks survive elevated temperatures of, say, up to 600&deg; to 800&deg; F. or higher, for extended periods of time. The inventive system for marking workpieces for their identification includes a laser that emits a beam select band of radiation and a coating system for application to a workpiece to be marked. The coating system includes two coats of paint, a topcoat and a basecoat which paints have been coated sequentially on the workpiece. The basecoat is an at least partially-cured, laser-blackenable paint which has been marked with fragile product identification indicia by the laser beam, after which a clear topcoat has been applied thereover. The laser generates fragile product identification indicia on the workpiece by its beam being directed onto the basecoat for its blackening to generate the fragile product identification indicia by the selective charring of said basecoat. The clear topcoat seals the fragile product identification indicia. High temperature use of the label can be realized by using a siloxane or other high-temperature paint for both the basecoat and the topcoat.

Method for identifying an object having a surface of a given color associates a colored zone with the surface of the object. The zone is machine readably contrasting in color compared to the surface color. The colored zone is ablatively imaging to produce one or more of machine readable images, human readable images, or graphics. The contrast in color between the colored zone and the surface is machine readable. Advantageously, at least two colored zones are associated with the object to be identified. One or more of these colored zones can be ablatively marked. One or more of these colored zones also can be used to sort and/or identify the object by color.

A method for imaging a product with a pattern commences by forming a film of a wet or tacking marking material on a clich&eacute;. A negative of the pattern is ablatively imaged into the film on the clich&eacute;. The negative image then is pressure transferred from the clich&eacute; onto a marking pad. Finally, the negative image is pressure transferred from the marking pad onto the product. Preferably, the clich&eacute; where the film is formed contains recesses. The apparatus, which images the product, has a moveable clich&eacute; having a recessed pocket. An ink reservoir transfers ink into the recessed pocket. A laser imaging system images a pattern into ink contained in the recessed pocket. A stamp pad is moveable from a home position to contact the imaged pattern for pressure transferring the pattern onto the stamp pad, and moveable to a printing station to pressure transfer the pattern onto a product.

Method for marking hot glass article having a surface uses a flexible carrier ribbon bearing a laser ablatable, high temperature, diffusely reflective coating, preferably white in color. A pattern is imaged in said coating on carrier ribbon by laser ablation. The patterned carrier ribbon is pressed against the surface only for a time adequate for transferring the patterned coating to the surface. The carrier ribbon then is released from pressing against the surface. The transferred image thickness may be limited by solid particles within the coating.
