Abstract

809,672. Compression-moulding machines. COAL INDUSTRY (PATENTS) Ltd. July 4, 1955 [July 2, 1954], No. 19464/54. Class 87(a). Powdered material, e;g. metal or coal, is compressed in a mould 10 by coaxial plungers 12a, b. The plungers remain in the same relative positions until the oil pressure in a cylinder 12c exceeds a predetermined value, when a relief valve 17 opens and the pressure of the main hydraulic or mechanical ram 18 is transmitted to the plunger 12b only. A pump 14 refills the cylinder 12c for the next pressing operation. A similar press is described with reference to Fig. 3 (not shown) having a relief valve, Fig. 2 (not shown). This relief valve allows the drop in pressure in the cylinder 12c to take place rapidly. The lower end of the plunger 12b may be conical, domed or flat and that of the plunger 12a flat or frusto-conical. Specification 807,433 is referred to.
