    Abstract: 1,090,440. Rotary table compression moulding machine. APPLIED RESEARCH LABORATORIES Inc. Nov. 1, 1965 [Nov. 19, 1964], No. 28159/67. Divided out of 1,090,439. Heading B5A. A rotary table compression moulding machine, particularly for making briquettes for subsequent X-ray analysis, comprises an intermittently rotating hub 40 carrying radial arms 44-49 each of which is provided with a through bore 50. Each arm carries upper and lower pressing pistons, 52 and 54 which are pivoted to the outer ends of levers 56 and 58, the levers themselves being centrally pivoted about rollers 98 mounted upon the arm. The levers are moved along the arm, to bring the pistons into a position overlying the bore, by cam actuated rods 61 and 62 connected to rollers 98, and are pivoted, to insert the pistons into the bore, by means of second, cam actuated rods 62 and 64 connected to the inner ends of the levers. In operation, starting from a position in which the upper piston is radially retracted and the lower piston is located in the bore, each arm is first indexed to a station B, where the bore is filled by a hopper 76, and then to a station D, during which time the upper piston is forwarded and pivoted into the bore to effect a preliminary compression. At station D, the pistons are engaged between upper and lower press jaws to fully compress the material, after which the lower piston is lowered and radially retracted, the upper piston is lowered to push the formed briquette from the bore, and the arm is indexed to a last station F. At station F the lower piston is forwarded to knock the briquette off the lower end of the upper piston on to a take-off device such as conveyer 74.
