  • Method for determining the proportion of at least one material in a moving mixture of materials
    Patent number: 4374326
    Abstract: The proportion of a radioactive material in a moving mass of material is determined with a sensor which derives an output signal proportional to the mass of radioactive material. The output signal is calibrated against known reference values to give a quantitative value of mass. Problems associated with inhomogeneity of material distribution are overcome by averaging the sensed radiation over a time period. Background radiation can be sensed to determine sufficiency of material or it can be shielded from the sensor.
    Type: Grant
    Filed: August 15, 1980
    Date of Patent: February 15, 1983
    Assignee: Coal Industry (Patents) Limited
    Inventors: John S. Wykes, Ian Adsley
  • Method of and apparatus for determining the nature of transported material
    Patent number: 4359639
    Abstract: A coal/stone mixture transported on a conveyor is investigated by subjecting it to two radiation beams of differing energies. In a preferred embodiment, the higher energy radiation is collimated into a pencil beam and the lower energy radiation into a fan beam. Detector shielding prevents substantial interference of close-to-surface reactions within the detector deriving from the higher energy beam with detection of the lower energy beam.

  • Radiation detectors supported by resilient optical coupler
    Patent number: 4323778
    Abstract: A sensor which is robust for use in an industrial environment. The sensor employs two scintillation crystals to offer a sufficient crystal volume and the crystals are optically coupled through a silicone rubber compound. The compound also allows the crystals to vibrate independently so that they do not shatter. A single photomultiplier detects scintillation occurring in all the crystals.

  • Method of and apparatus for determining the proportion of at least one material in a moving mixture of materials
    Patent number: 4275298
    Abstract: The proportion of a radioactive material in a moving mass of material is determined with a sensor which derives an output signal proportional to the mass of radioactive material. The output signal is calibrated against known reference values to give a quantitative value of mass. The sensor includes a plurality of scintillation crystals. Problems associated with inhomogeneity of material distribution are overcome by averaging the sensed radiation over a time period.
