  • Machine for heat treating objects of great length
    Patent number: 4156805
    Abstract: The machine comprises two electrodes connected to a high frequency electric current generator and adapted to subject the object to be heated to an electric field. The first electrode comprises a table provided with at least one opening through which projects a roll for guiding the travel of the object. A plurality of pairs of electrically insulating rollers for exerting pressure on the object are mounted on the table and at least one pair is movable with respect to the others so as to curve the object as heat treatment proceeds. Section members supporting the rollers extend the table of the electrode and are in electric contact with a support box structure for the second electrode which is connected to earth.

  • Microbiological process for controlling the productivity of cultivated plants
    Patent number: 4155737
    Abstract: According to the invention, the productivity of cultivated plants is controlled by a microbiological process. At least one telluric microorganism having a favorable rhizospheric effect on a plant is embedded in a polymer gel. Fragments of the gel are then inoculated into the rhizosphere of the plant. The invention also relates to a process for preparing the required fragments of polymer gel. Polymerization of the gel is carried out in the presence of a culture of the desired microorganism, and the polymer block is thereafter broken up prior to use.
