William Andrew Romanauskas has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6723238
    Abstract: A centrifuge bucket, for holding a first article, further comprises a compartment for holding a second article, and an arrangement for securing the compartment to an outer surface of the centrifuge bucket.
    Type: Grant
    Filed: September 19, 2001
    Date of Patent: April 20, 2004
    Assignee: Kendro Laboratory Products, L.P.
    Inventors: William Andrew Romanauskas, Edward Thomas Sheeran, Jr.
  • Patent number: 6638203
    Abstract: In a centrifuge comprising a drive shaft assembly, a diaphragm disposed about the drive shaft assembly reduces noise and vibration. The diaphragm permits the drive shaft assembly to pivot off a vertical axis while substantially limiting horizontal displacement thereof. Also, where a centrifuge includes a rotor shaft and a drive shaft, a member situated between the rotor shaft and the drive shaft substantially limits vertical displacement of the rotor shaft while allowing angular deflection of the rotor shaft with respect to the drive shaft.
    Type: Grant

  • Patent number: 6063017
    Abstract: A method and apparatus which are capable of controlling the motion of a rotor body fragment after a rotor failure has occurred within a centrifuge assembly which comprises a rotor body, a centrifuge chamber and a centrifuge lid. The moment of the rotor body fragment can be controlled such that it moves along the centrifuge chamber away from the centrifuge lid by any of the following: (a) adjusting the center of gravity of the rotor such that it is below the strike point plane of the rotor; (b) adjusting the shape of the centrifuge chamber to conform to the rotor body shape; (c) sloping the guard ring such that the lower portion is furthest away from the centrifuge chamber; (d) varying the strength or stiffness of the guard ring or centrifuge chamber at or above the center of gravity of the rotor body fragment; and (e) adding a ring member to the top of the centrifuge rotor body.

  • Patent number: 5921150
    Abstract: A rotating apparatus including a shaft having a rotor mounting location disposed at a predetermined position on the shaft, the rotor mounting location subdividing the shaft into a first and a second portion, a motor for rotating the shaft connected to the first portion of the shaft, a tachometer for monitoring the rotational speed of the shaft; and a stabilizer connected to the second portion of the shaft and responsive to the tachometer for imposing an axially directed force on the shaft, to minimize vibration of the shaft at critical rotational speeds.

  • Patent number: 5650578
    Abstract: An energy monitoring arrangement that is operatively associated with a centrifuge instrument monitors the magnitude of applied accelerating energy that is used to accelerate a rotor and to interrupt the continued application of accelerating energy if the magnitude of the applied accelerating energy exceeds a predetermined reference energy value. Preferably, the net applied accelerated energy to the rotor is monitored and used in the comparison with the energy reference. The invention may also be used in a predictive manner to provide, early in the centrifugation run, an indication of the energy of a rotor at an operator-ordered set velocity.
