摘要： In combustion fired magnetohydrodynamic power systems conventional fuels such as coal, oil, natural gas and the like are first completely burned, and then shock waves are generated in the combustion products by means of small amounts of explosives which are preferably initiated by pulsed lasers. Thus, highly ionized particles of great flow velocities are obtained which are supplied into a usual MHD generator to induce a ripple current in a load circuit at high efficiency.

摘要： The invention concerns apparatus for measuring the velocity of low frequency mechanical vibrations, comprising two springs between which a vibratable mass is secured, two electric coils mechanically coupled to the mass, a permanent magnet core in each coil which is stationary relative to its associated coil, one coil being a measuring coil while the other is a feedback coil; and a current generator having a control input to which the measuring coil is connected while the feedback coil is connected to the generator output, the connection polarities being so selected as to produce negative feedback.
