DEFINITION

Classification: 428/560

(under subclass 553) Subject matter in which metal particles are held in discontinuous array by a nonmetal material which functions as a binder or matrix for the particles.

(1) Note. Contrary to the general rule for patent placement in these subclasses (544+), a patent is not placed in this subclass when the nonparticulate component is generically claimed, if such component is disclosed as being confined to those materials specifically provided for in the subclasses indented hereunder.

SEE OR SEARCH THIS CLASS, SUBCLASS:

208, 328 and 330, for a plural layer nonmetallic* sheet or

web in which one layer contains metal particles.

556, for a composite having plural adjacent nonparticulate metal components and a particulate component which includes a nonmetal.

558, for materials similar in their ultimate composition and function to those contained herein, and the search notes thereto. SEE OR SEARCH CLASS

313, Electric Lamp and Discharge Devices,

326+, for electrode and shield structures which are more than mere stock materials.

427, Coating Processes,

59+, for coating processes for producing electrodes used in electric welding, and subclass 196 for processes of applying particles and a binder from different sources upon a base.
