  • Patent number: 6555360
    Abstract: For direct and on-line study of the physiological states of cell cultures, a robust flow injection system has been designed and interfaced with flow cytometry (FI-FCM). The core of the flow injection system includes a microchamber designed for sample processing. The design of the microchamber allows not only an accurate on-line dilution but also on-line cell fixation, staining, and washing. The flow injection part of the system was tested by monitoring the optical density of a growing E.coli culture on-line using a spectrophotometer. The entire growth curve, from lag phase to stationary phase, was obtained with frequent sampling. The system is thus particularly useful since it operates automatically without direct operator supervision for extended time periods.

  • Patent number: 5967902
    Abstract: A golf putter and method is disclosed which allow accurate sighting and positioning of the golf putter head relative to the target or hole, and which has perpendicular elongated teeth that run along the bottom face of the putter head thereby increasing friction and reducing the resultant tendency for the putter head to twist when moving from a rearward optically accurate alignment position to a putting position. The accurate sighting is possible by tilting the golf putter rearward and sighting along the face and top of the putter head. This tilting causes a rear parallel tooth to engage the turf, keeping the putter head in position As the golfer moves from the sighting position.

  • Patent number: 5785323
    Abstract: A seal for preventing leakage of fluid from between a first member and a second member, the second member is capable of moving toward and away from the first member, the seal is adapted for engaged contact with the first member and the second member so as to prevent leakage of fluid between the first member and the seal and between the second member and the seal, the seal being softer than the second member such that friction between the seal and the second member wears the seal faster than the second member, the seal being adapted to retain a tight seal against the second member as long as the seal has not worn beyond a specified depth; and a conductor for placement about the second member, the conductor being attached to the seal at the specified depth so as to contact the second member when the seal has worn to the specified depth, such that the existence of electrical continuity between the conductor and the second member indicates that the seal requires replacement, the conductor is positionally associat

  • Patent number: 5540448
    Abstract: A seal prevents leakage of fluid between the seal and a moving surface. The seal includes a seal body and a conductor. The seal body can undergo wear to a specified depth before the seal requires replacement. The conductor is placed about the moving surface such that wear of the seal body to a specified depth brings the conductor into contact with the moving surface. The conductor may be embedded in the seal body or otherwise attached to position the conductor about the moving surface. Wear of the seal body to a specified depth can be checked by checking electrical continuity of the conductor. The existence of electrical continuity between the conductor and the moving surface may indicate that the seal requires replacement. Alternatively, the conductor may be positioned such that the conductor has worn entirely through when the seal body has worn to a specified depth, with a loss of electrical continuity through the conductor indicating that the seal requires replacement.
