摘要： Workpieces of materials highly resistant to deformation or compaction but capable of plastic deformation under high pressure are subjected to transient, very high pressure applied to elements of the workpiece progressively, until the whole workpiece has been traversed. The pressure may be applied by a patterned formation which imposes its profile on the workpiece, or the workpiece may be kneaded into intimate contact with the pattern to receive its impress.

摘要： This invention relates to a method of forming headed articles such as bolts from round bar. The bar is rotated in the throat between two rollers and has a part extending beyond the roller surface. A stylus is pressed against the face of the projecting end to form an indentation in this face of the rolling bar and as the indentation increases in size a head is formed on the bar. The head can be subjected to further working if necessary.

摘要： THE INVENTION IS CONCERNED WITH THE METHOD AND APPARATUS FOR GENERATING OR DISSIPATING VERY HIGH PRESSURES BY MEANS OF ENCLOSING A REACTION ZONE IN A CONTINUOUS MASS OF MATERIAL OF LOW TENSILE STRENGTH AND HAVING NO SUDDEN CHANGE IN SECTIONAL SHAPE. THIS MATERIAL IS ENCLOSED IN A SHEATH OF HIGH TENSILE STRENGTH MATERIAL AND PRESSURE MAGNIFYING OR REDUCING BODIES ARE INCLUDED IN THE MASS OF MATERIAL. THIS ASSEMBLY ENABLES VERY HIGH PRESSURES TO BE GENERATED IN THE REACTION ZONE AND CONTROLLED THROUGH ENERGY ABSORBED BY INTERPARTICULATE FRICTION IN THE MASS OF THE LOW TENSILE STRENGTH MATERIAL.
