To determine what happens in a jig bed during a cycle of stroke, a lot of studies have been made by many men, but results were not same. The study of alternate opening and closing of a bed on each stroke is very important. (1) A rubber ball was submerged into the bed of particles. The rubber ball and the U tube were connected through a rubber pipe. The pressure was indicated by the U tube when neighboring particles pressed the rubber ball. (2) The pressure between particles and particles was measured by a. a. c. bridge method electically. (3) The pressure difference in a jig bed, during pulsion and suction phases was measured by carbon granule for the telephone transmitter. Diplacement of diaghram pressed by particles in the bed was measured by using carbon granule. Fig. 9 is a oscillogram of bed pressure of trialy made apparatus.
