Opposite magnetic poles of the magnets are adjacent, the magnets are hinged on a cross shear-type expansion bracket, retaining-and-guiding inner sleeves are sleeved outside the magnets, upper end seats and lower end seats are disposed at both ends of the retaining-and-guiding inner sleeves respectively andconnected with both ends of the cross shear-type expansion frame respectively, and damping springs are installed between the upper end seats and the lower end seats. Since opposite magnetic poles of adjacent magnets are arranged oppositely, the closer the distance, the greater the attraction; when severe vibration occurs, the damping springs are compressed and deformed greatly, the elasticity of the damping springs increases linearly with the deformation; when the deformation of the damping springs increases, the distance between adjacent magnets decreases, the attraction increases geometrically, a part of increased elasticity is offset, in other words, impact force to car frames is decreased. By the stable-type damping device, stable damping can be realized when the elasticity of damperscan be kept changing mildly and nonlinearly within a bigger deformation range.

The apparatus includes an inner conduit having an inlet for receiving the diluent / dispersion stream; an outer conduit having an inlet for receiving the hydrocarbon stream and an outlet for dispensing a mixture including the hydrocarbon and the dispersion / diluent streams; the outer conduit concentric to the inner conduit to define at least a first annular space and a second annular space; the first annular space being located downstream of the inlet of the outer conduit, the first annular space enabling formation of a thin film of the hydrocarbon stream between an outer surface of the inner conduit and an inner surface of the outer conduit; the second annular space being located downstream of the first annular space, the second annular space having a width greater than a width of the first annular space; and the inner conduit located at about the second annular space includes a first set orifices disposed on a periphery thereof for dispensing a first portion of the dispersion / diluent stream into the thin film of hydrocarbon stream to cross-shear the thin film and form the mixture including the hydrocarbon and the dispersion / diluent streams.
