  • Patent number: 6979404
    Abstract: A filtration device having a plurality of membrane modules is provided. Each of the plurality of membrane modules has first and second permeable sheets that are separated by a spacer, a first ring disposed around a perimeter of a first hole in the first permeable sheet, and a second ring disposed around a perimeter of a second hole in the second permeable sheet, the second hole in alignment with the first hole. The first ring of each of the plurality of membrane modules is in abutment with the second ring of a preceding one of each of the plurality of membrane modules so that the plurality of membrane modules are interconnected for communication therebetween. Some embodiments further provide a third sheet that disposed between successively adjacent membrane modules.

  • Patent number: 4155033
    Abstract: A drive system for tape transducer capstan drive control for synchronously controlling capstan drive over a wide speed range, the system being a phase locked loop which encompasses the motor, all drive components, and the capstan. The capstan drive to a tape record receives rotation from a capstan drive motor which also provides a rotational sense output. A control circuit receives the sense output as well as a selected reference frequency signal and processes the signals in accordance with selected binary control input thereby to generate the requisite drive voltage for energization of the capstan drive motor.
