Abstract: In the present invention, a protective coating is preferably formed as a plurality of dots upon a surface to be protected. The dots have a selected size, cover a selected amount of the underlying surface, and are preferably isolated from one another by uncoated surfaces. This coating not only provides the coated substrate or object (and the cured coating itself) with significantly increased flexibility and formability, but also with a wide range of possible surface finishes and textures. Due to the increased coating flexibility and formability, the coated substrate or object can be partially or even fully cured prior to forming operations such as injection molding or film shaping. The substrate or object is therefore less susceptible to damage from handling and from machine operations. One highly preferred coating embodiment is produced with ink having a controllable stipple amount for a significantly increased range of possible coating finishes and textures.

Abstract: This invention relates to a method of dechlorinating coal, which comprises treating washery-processed coal having a particle size from 1 to 12 mm with aqueous ammonia having a concentration from 1 to 18 M for from 3 to 25 hours.The invention will be of use in the preparation of coal for coal utilization plants so that the coal is less likely to cause corrosion.
