Abstract: A method for obtaining vibrational and lateral movement within rotatable receptacles is disclosed. The lateral movement is achieved by the interruption of the simple circular motion of a receptacle by slight projections in the circular path of the receptacles. The interruptions cause the materials within the receptacles to vibrate and move laterally rather than continue in a strict circular path. The interruptions may take the form of studs or projections on the outer circumference of the receptacles being rotated or may take the form of studs or projections located on the means rotating the receptacles. The rotatable receptacles are classically rotated by belts.

Abstract: A process is disclosed for preparing a silver halide emulsion comprised of serially receiving a silver halide emulsion at an upstream location, supplying the silver halide emulsion in a further prepared form at a downstream location, and transporting the silver halide emulsion between the upstream and downstream locations while it is being further prepared. The silver halide emulsion is divided into discrete segments as it is received at the upstream location. The discrete segments of the silver halide emulsion are transported between the upstream and downstream locations in the sequence of their formation. The emulsion can be finished as it is transported to the downstream location. The silver halide grains can be shelled during transport. In still another application a converted-halide emulsion can be formed during transport to the downstream location.
