摘要: An apparatus for forming a sinterable compact of a powder comprises a pair of respective shafts displaceable toward one another by the action of respective cams and serving to displace opposing ram members to compact a powder between them. Respective plates carrying the ram members are entrained with the shafts and are displaced in the opposite direction by respective pairs of pneumatic cylinders. The rams are thereupon displaced at high rate against the precompacted powder by energizing a disk-shaped coil which repels electrodynamically the plate carrying the rams.

摘要: An apparatus for lubricating the internal wall of moulds for blanks comprises a corona charger for charging electrically the lubricant which is then injected into the mould. This latter is maintained at an electric potential such as to attract the lubricant and cause it to be deposited on the inside walls of the mould.
