  • Standardization of penetrating radiation testing system
    Patent number: 4154672
    Abstract: Standardization is provided to control system gain of a penetrating radiation testing system by periodically inspecting a reference object in the same manner as the product samples so as to generate a stabilization signal which is compared to a reference signal. The difference, if any, between the stabilization signal and the reference signal is integrated and the integrated signal is used to correct the gain of the system.

  • 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.
