a fluent or bulk material, which material has plasticity as a property,
into a self-sustaining article or preform of desired shape or which
reshapes or resizes a plastic or "green" preform

2. Apparatus for shaping of molten materials including metal,
but excluding glass, where no molding surface is employed, e.g.,
by melt comminution or spheroidizing.

CROSS-REFERENCE ART COLLECTIONS
The following subclasses are collections of published disclosures
pertaining to various specified aspects of the shaping art which
aspects do not form appropriate bases for subclasses in the foregoing
classification (i.e., subclasses superior hereto in the schedule),
wherein original copies of patents are placed on the basis of proximate
function of the apparatus. These subclasses assist a search based
on remote function of the apparatus and may be of further assistance
to the searcher, either as a starting point in further related fields
of search inside or outside the class. Thus, there is here provided a
second access for retrieval of a limited number of types of disclosures.
Disclosures are placed in these subclasses for their value as references
and as leads to appropriate main or secondary fields of search,
without regard to their original classification or their claimed subject
matter. The disclosures found in the following subclasses are examples,
