DEFINITION

Classification: 505/425

Producing powder or short fiber (i.e., less than 15 cm) by spraying, dropping, or slinging of solution, suspension, or melt (e.g., spray-drying, atomizing, etc.):

(under subclass 300) Process wherein a liquid solution, suspension, or melt of superconducting material is subjected to atomizing, dropping, extruding, or disintegrating by centrifugal action to form by surface tension, or drying into (a) particulate, or (b) short (i.e., less than 15 cm) fiber form.
