20120064254 | A METHOD AND A DEVICE FOR COATING CERAMIC MATERIAL FIBERS IN METAL BY A LIQUID TECHNIQUE - A method of coating ceramic material fibers in metal using a liquid technique and a device implementing the method. The method maintains a charge of molten metal in levitation in a substantially spherical shape inside a crucible and causes a tensioned ceramic material fiber to travel at a predetermined speed between a bottom pulley and a top pulley disposed on either side of the crucible such that a portion of fiber is immersed in the charge to be covered in a metal coating. During coating, the portion of fiber that is immersed in the charge is shifted as a function of the remaining volume of the charge such that the instantaneous height of fiber that is immersed in the charge remains substantially constant throughout the coating operation. | 03-15-2012 |
20150056378 | METHOD OF MANUFACTURING PALLADIUM THIN FILM BY USING ELECTROLESS-PLATING METHOD - Provided is a method of manufacturing a palladium (Pd) thin film by using an electroless-plating method, the method including: manufacturing a reaction mixture by adding Pd salt and an alkaline pH regulator to an alcohol-water mixed solution; and forming a Pd thin film by loading and stirring the reaction mixture in a substrate. Accordingly, a Pd thin film having a surface enhancement Raman scattering (SERS) effect may be easily manufactured without having to use expensive additional equipment, such as a vacuum device, and in detail, electroless-plating may be performed even on an insulating substrate formed of, for example, glass. In addition, since a size of the Pd thin film manufactured on the substrate may be adjusted, the Pd thin film may be applied to various electrochemical products. | 02-26-2015 |

20150140225 | METHOD AND DEVICE FOR HOT-DIP COATING A METAL STRIP WITH A METAL COVERING - 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. | 05-21-2015 |
