  • Apparatus for and method of measuring product mass
    Patent number: 4117935
    Abstract: A novel apparatus for and method of measuring product mass is described in which products are sequentially conveyed to an inspection station where the entire bulk of each product is substantially instantaneously irradiated with a beam of radiation. Scattered radiation from the product thus irradiated is detected to provide an electrical signal whose magnitude is representative of the mass of the product. The products can be sorted in accordance with their measured mass.
