  • Patent number: 5638657
    Abstract: A system and method for automatically feeding, inspecting and diverting tablets for continuous filling of tablet containers includes a tablet conveyor system which divides the tablets in a plurality of tablet streams for inspection by color, size and shape. Following the tablet inspection, each tablet passes through a tablet diverter which diverts the tablets to a recycle stream, reject stream or one of two bottle filling positions based upon instruction from the inspection. A bottle conveyor system is provided which feeds empty bottles into a bottle escapement mechanism which positions the empty bottles for filling. Filled bottles are moved from the bottle escapement mechanism to an exit conveyor. The entire system is computer controlled by various control mechanisms to enable the system to be fully operational without operator assistance.

  • Patent number: 5174829
    Abstract: A method and apparatus are provided for removing surface liquid from elongate articles such as cans. After sterilization of filled cans, surface liquid can permit microorganisms to proliferate and risk contamination of the contents. The apparatus comprises means (10) for applying a jet of gas at an acute angle to the surface of the elongate article, means for causing relative motion between the article and the jet, and suction means (12) provided downstream as considered in the direction of the jet, for applying suction to a region of the surface of the elongate article whereby surface liquid is removed therefrom.
