  • Patent number: 4043764
    Abstract: Combustible bricks are manufactured from plant materials by agglomeration under pressure of these materials after pulverization and drying. Prior to this, the plant materials are subjected to a fermentation and, in the course of fermentation, to a pulverization treatment while controlling this fermentation so as to obtain a destructuration of the cellulosic tissues of the plant materials without producing separation of the lignin.This process produces small bricks having a good strength and a low moisture content.

  • Patent number: 4039839
    Abstract: Thorium tetrabromide has been found to exhibit fluorescence and radioluminescence with emission of blue light in the range from 3400 to 4800 A with a maximum around 4000 A in response to electromagnetic waves shorter than 3000 A, whether ultraviolet, X or gamma rays and also in response to energetic charged particle radiation, such as alpha rays, beta rays, protons and heavy ions. Because of the radioactive decay of thorium, there is a background autoluminescence. Crystals of thorium tetrabromide are transparent to its luminescence radiation and are particularly suitable for radiation detectors and measurements, frequency converter, standards, radioisotopic microgenerators of electricity, and the like. They are also useable as neutron flux detectors, for thermal and fast neutrons because the component elements of the crystal react with neutrons to respectively produce neutrons activation reactions and fission reactions.

  • Patent number: 4027657
    Abstract: A method and an apparatus for measuring the variations of the foetal heart rate particularly during labor. According to this method, an average value is determined from zones where no deceleration occurs. In order to avoid variations due to small parasitic signals, this average value is compared with a filtered value, corresponding to the average value during a small number of periods of the electrocardiogram. This apparatus allows a practitioner to obtain a binary indication on the decelerations of foetal heart rate and accordingly an indication on the possible foetal stress.
