Abstract
Abstract A method for the implosive consolidation into a solid body of a mass of free particles, which mass consists, selectively, entirely of amorphous particles, or a mixture of amorphous and nonamorphous particles. During the consolidation act, pressure and temperature are controlled in a manner which assures that the consolidated amorphous particles in the solid body exhibit substantially the same amorphous characteristics as those displayed by the unconsolidated, free amorphous particles.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
108 words
A method for the implosive consolidation, into a solid body, of a particulate mass comprising free amorphous particles, said method including the steps of assembling such a mass to define, in the assembled but unconsolidated state, a chosen configuration for such a body, imploding the assembled mass by an external, substantially surrounding explosive force in a manner bonding the particles in the mass as a unit to form a solid body having such chosen configuration, and controlling said imploding in such a fashion that the contribution made to such body by such amorphous particles retains substantially the same amorphous characteristics as those exhibited by the unconsolidated amorphous particles.
Claim 2
Independent Claim
108 words
A method for the implosive consolidation, into a solid body, of a particulate mass comprising free amorphous particles, said method including the steps of assembling such a mass to define, in the assembled but unconsolidated state, a chosen configuration for such a body, imploding the assembled mass by an external, substantially surrounding explosive force in a manner bonding the particles in the mass as a unit to form a solid body having such chosen configuration, and controlling said imploding in such a fashion that the contribution made to such body by such amorphous particles retains substantially the same amorphous characteristics as those exhibited by the unconsolidated amorphous particles.
Claim 3
Dependent Claim
20 words
The method of claim 1 which is performed with a particulate mass including a mixture of amorphous and nonamorphous particles.
Claim 4
Independent Claim
145 words
A method for the implosive consolidation, into a solid body, of a particulate mass comprising free amorphous particles, where such amorphous particles are characterized by a known co-consolidation interface pressure and a known antiamorphic temperature limit, said method including the steps of assembling such a mass to define, in the assembled but unconsolidated state, a chosen configuration for such a body, producing an explosion in a region at least partially surrounding the assembled mass to create an imploding force thereon which generates a pressure on the totality of the assembled mass that is at least equal to such co-consolidation interface pressure, and which creates, in the space occupied by the mass, a temperature throughout the duration of the explosion which is less than such antiamorphic temperature limit, and by said producing, imploding the assembled mass to form such a body having such a chosen configuration.
Claim 5
Independent Claim
145 words
A method for the implosive consolidation, into a solid body, of a particulate mass comprising free amorphous particles, where such amorphous particles are characterized by a known co-consolidation interface pressure and a known antiamorphic temperature limit, said method including the steps of assembling such a mass to define, in the assembled but unconsolidated state, a chosen configuration for such a body, producing an explosion in a region at least partially surrounding the assembled mass to create an imploding force thereon which generates a pressure on the totality of the assembled mass that is at least equal to such co-consolidation interface pressure, and which creates, in the space occupied by the mass, a temperature throughout the duration of the explosion which is less than such antiamorphic temperature limit, and by said producing, imploding the assembled mass to form such a body having such a chosen configuration.
Claim 6
Dependent Claim
20 words
The method of claim 3 which is performed with a particulate mass including a mixture of amorphous and nonamorphous particles.
Claim 7
Independent Claim
83 words
A method for the implosive consolidation of free amorphous particles into a solid amorphous body comprising assembling such particles to define, in the assembled but unconsolidated state, a chosen configuration for such a body, and imploding the assembled particles by an external, substantially surrounding explosive force in a manner bonding the particles as a unit to form such a solid body having such a chosen configuration, with the body of bonded particles exhibiting substantially the same amorphic characteristics as did the prebonded particles.
Claim 8
Independent Claim
83 words
A method for the implosive consolidation of free amorphous particles into a solid amorphous body comprising assembling such particles to define, in the assembled but unconsolidated state, a chosen configuration for such a body, and imploding the assembled particles by an external, substantially surrounding explosive force in a manner bonding the particles as a unit to form such a solid body having such a chosen configuration, with the body of bonded particles exhibiting substantially the same amorphic characteristics as did the prebonded particles.
Claim 9
Independent Claim
137 words
A method for the implosive consolidation of free amorphous particles into a solid amorphous body, where such particles are characterized by a known co-consolidation interface pressure and a known antiamorphic temperature limit, said method comprising assembling such particles to define, in the assembled but unconsolidated state, a chosen configuration for such a body, producing an explosion in a region at least partially surrounding the assembled particles to create an imploding force thereon which generates a pressure on the totality of the assembled particles that is at least equal to such co-consolidation interface pressure, and which creates, in the space occupied by the particles, a temperature throughout the duration of the explosion which is less than such antiamorphic temperature limit, and by said producing, imploding the particles to form such a consolidated body having such a chosen configuration.
Claim 10
Independent Claim
137 words
A method for the implosive consolidation of free amorphous particles into a solid amorphous body, where such particles are characterized by a known co-consolidation interface pressure and a known antiamorphic temperature limit, said method comprising assembling such particles to define, in the assembled but unconsolidated state, a chosen configuration for such a body, producing an explosion in a region at least partially surrounding the assembled particles to create an imploding force thereon which generates a pressure on the totality of the assembled particles that is at least equal to such co-consolidation interface pressure, and which creates, in the space occupied by the particles, a temperature throughout the duration of the explosion which is less than such antiamorphic temperature limit, and by said producing, imploding the particles to form such a consolidated body having such a chosen configuration.
