Abstract: A system for removing iron ore particles adhered by magnetic hysteresis to a magnetic matrix of a vertical magnetic separator, the vertical magnetic separator having a separation ring with a magnetic matrix; an ore feed inlet an ore accumulation vessel positioned in the lower portion of the magnetic matrix and having an outlet for low magnetic-susceptibility material; a magnetic field-generating device adapted to generate a magnetic field in the region of the accumulation vessel; at least one collection tray positioned internally to the magnetic matrix and adapted to collect material with greater magnetic susceptibility detached from the magnetic matrix; and a collecting container adapted to receive the material with greater magnetic susceptibility from at least one collecting tray. The system further includes a demagnetizer; a mechanical device for cleaning the magnetic matrix positioned at a position subsequent to the demagnetizer; and at least one device generating jets of compressed air.

Abstract: A gas turbine engine rotor assembly comprises a torque tube, turbine stage and stiffening mass. The torque tube comprises a shaft extending from a forward location to an aft end, and a shaft fastening flange disposed at the aft end. The turbine stage comprises a disc, a disc adapter extending forward from the disc, and a disc fastening flange extending from the disc adapter and couplable to the shaft fastening flange at an interface. The stiffening mass is positioned proximate the interface to reduce operational stress in the torque tube. A method of reducing operational stress in a rotor assembly comprises de-stacking a rotor stack, separating a first stage rotor disc adapter from a torque tube, attaching a stiffening mass to an inner diameter of one or both of the disc adapter and the torque tube, attaching the disc adapter to the torque tube, and re-stacking the rotor stack.

Abstract: My invention “STRONG WAVE” is a design of a geometric figure, this figure can be used itself or combined with itself (two or more combinations), in the same size or different sizes, in a lot of different positions; resulting in graphic symbols, patterns, logos and others new designs.

Abstract: A civil engineering structure having an arched wall including a plurality of curve shaped elements. Each element bears against one or more other similar elements and has a recess arranged in an outer face for casting a concrete assembly capping piece and reinforcements. Each element also includes at least one rigid bearing piece fastened to the element and has, at a free end of the rigid bearing piece, a surface with a non-planar profile. The rigid bearing piece comes to bear against a similar piece of another element located opposite it. The two rigid bearing pieces have complementary profiles making it possible for them to be wedged vertically.
