Class Information
Number: 72/54
Name: Metal deforming > By application of fluent medium, or energy field
Description: Subject matter comprising a step of, or means for, effecting mechanical treatment of metal work by (a) the conduction of pressurized fluent material in gaseous, liquid, plastic, or random particulate form into engagement with a portion of the surface or work and/or the development of pressure in fluent material while it is engaged with work, or (b) the direction of electric, magnetic, or radiant energy toward work in such manner as to induce mechanical accelerating force therein.
