  • Process for manufacturing thermosetting resins resistant to boiling water and capable of being substituted for phenol-formol resins, and resulting resins
    Patent number: 5194551
    Abstract: The process allows obtaining thermosetting resins resistant to boiling water. A chemical body having at least two methylol functions per molecule, is reacted with a chemical compound having at least two hydrogen functions per molecule, so as to create polymerization links of the type: ##STR1## Such resins can be used in particular for manufacturing plywood or chipboards.
    Type: Grant

  • Solar furnace
    Patent number: 4556047
    Abstract: The solar furnace is constructed of evacuated glass block solar elements that include an interior face, or surface, of zinc. Because of this material, substantial solar radiant energy is retained and radiated to the interior of the furnace, permitting the furnace to reach temperatures of 300.degree. C. and more when located at latitudes between the 35th parallels. Evacuated insulating elements contain the furnace's heat, each element being an evacuated block with one or more preferably reflective interior panels.
