  • Incineration method, particularly for spent graphite
    Patent number: 5513582
    Abstract: The method of incinerating a combustible material (1) comprises, before custion, the following steps:dividing (2) the material into particles,incorporating (3) the divided material into an aqueous medium at a rate of not more than 35% by weight of solid relative to the liquid,foaming and pressurizing the suspension thereby obtained, by incorporating an oxidizer gas (10) and surface-active additives (9) in a mixer (8) of the suspension.

  • Electrical machine having controlled characteristics and its application to a wind-driven machine
    Patent number: 4395669
    Abstract: The invention provides an electrical machine having an inductor and an armature at least one of which has at least two independent winding assemblies. The switching into and out of circuit of each winding assembly is controlled by a processor which receives monitoring parameters of the machine and desired value parameters, thereby controlling in real time the operating characteristics of the machine. The machine may be a wind-driven generator.
