ABSTRACT:
The presence of bubbles on such photographic material, as is well known, results in significant defects in the photographic materials produced so that it is important, in the manufacture of such photographic materials, to detect the presence of such bubbles in the liquid emulsion and to take appropriate remedial action. Described herein is a bubble detector comprising a conduit for liquid to be monitored, the conduit having opposing flattened, generally parallel walls, and a transducer engaged with one of the generally parallel walls and operable to apply alternating displacements to one of the generally parallel walls, at an ultrasonic frequency, in a direction generally normal to the generally parallel walls to transmit sonic or ultrasonic waves through liquid passing through the conduit.
