  • Patent number: 5099416
    Abstract: A buffer storage controller includes a read-out buffer address array, a write-in buffer address array and a buffer storage. An operand storage compare (OSC) detecting section compares a column signal and a row signal outputted from the read-out buffer address array to the buffer storage with those outputted by the write-in buffer address array to obtain an OSC detection signal.

  • Patent number: 4343695
    Abstract: A system for separation of non-magnetic metal particles in a mixture using an inclined rotating drum and the action of a travelling electromagnetic field. The mixture is introduced at the upper end of the inclined drum which is externally driven about its outer circumference in one direction. Simultaneously, a shifting electromagnetic field is generated along the lower part of the outer periphery of the drum in an opposite direction to rotation of the drum. The mixture as it travels through the drum is repeatedly moved upward in the direction of drum rotation along the inner wall due to frictional forces or in the direction of the shifting electromagnetic field. The successive raising and tumbling to the bottom of the drum provides complete stirring and promotes separation irrespective of particle size. The force of the electromagnetic field is not reduced by coverage with non-magnetic particles and a clear path exists since the interior of the drum is free of any obstructions.
