Method for depositing powder within carbonaceous article

Claim 1

A method for applying finely divided solid additive to the surfaces of carbon cloth layer components of a carbonaceous article, comprising: (a) supporting two circular platens in spaced relationship to each other on a flat movable transfer arm, the platens having center supports for the alignment of circular layers of carbon cloth placed thereon; (b) moving the transfer arm in back and forth movement about a first vertical pivot and a curved track in the flat surface, to alternately position each platen beneath the dispersion chamber; (c) rotating each platen through a limited degree of rotation as the platen is positioned beneath the chamber, each platen rotating upon a second vertical pivot attached to the transfer arm; (d) charging a measured amount of additive to the blowing tube, the additive charge being blown into and dispersed within the dispersion chamber by a stream of gas admitted to the tube, the end of the tube within the dispersion chamber being directed toward the closed end of the chamber, the additive then falling in a uniform layer upon a carbon cloth layer held on the platen; and (e) causing a subsequent movement of the transfer arm to carry the platen with the coated carbon cloth layer into a position for manual addition of another disc, the same movement positioning the other platen and disc beneath the dispersion chamber.
