Abstract

551,862. Lamp black &c. CHAMPION & CO., Ltd., C. H., and KOPPEL, L. Oct. 10, 1941, No. 13082. [Class 90] Lamp black &c. is consolidated for convenience in handling by withdrawing the air from between the particles and bring- ing them into intimate contact with one another, optionally by applying pressure. The lamp black is charged intc a cylinder 1 fitted with a piston 3 carrying a flexible connection 4 to a vacuum pump. The entrainment of lamp black into this connection is prevented by a baffle 6 attached to the piston and spaced apart from it and having a small clearance 8 between it and the cylinder walls. As the chamber is evacuated the piston falls pressing the carbon particles into contact. Subsequently a hydraulic ram may be applied in place of the handle 16 and the lamp black further compressed into a cake, which is discharged after removing the bottom 13 of the chamber. Alternatively it may be discharged in small pieces by passage through a wire screen substituted for the bottom of the chamber.
