Granted: 1994-08-30
Abstract: FIELD: electric separation of bulk materials. SUBSTANCE: electrostatic separator has hermetically sealed housing, electric field source and devices for feeding basic material and collecting separation products. Rotating truncated cone with inner surface coated with electret is mounted within hermetically sealed housing, with bottom of truncated cone functioning as centrifugal feeder. Working space of separator is insulated from environment and positioned within electronic gas. Communication with environment is provided through special-purpose locks. Separation of material is effectuated on rotating conical surface coated with electret as a result of interaction between grains of material adapted for separation and electret field. Paths of movement for fine grains depend basically on mirror reflection forces and for precharged grains of Coulomb force. EFFECT: increased efficiency of separation of fine-grain powders by size and composition and enhanced reliability in operation. 4 cl, 3 dwg

Granted: 1995-02-27
Abstract: FIELD: training aids. SUBSTANCE: kinematic disturbance of a vibrator is transmitted to a hollow cylinder through a base, cantilever. Coupling reaction toward internal cylinder is transmitted practically to fibers positioned on the right hand only at given directivity of fibers in internal cylinder. Rotational moment arises as a result to provide self-cranking of internal cylinder anti-clockwise. When moving hollow cylinder down, coupling reaction toward removable internal cylinder is transmitted practically to fibers positioned on the left hand only. As a result rotational moment arises again to act anti-clockwise. Having chosen a proper time interval, a counter of vibrating number cycles is used to measure number of cycles, and a tachometer is used to measure number of revolutions of internal cylinder as to hollow cylinder, and efficiency is estimated on the basis of relation between number of tachometer revolutions and number of vibrating cycles number indicated by the counter. EFFECT: high effectivity.
