    Abstract: A seal is provided having a resilient, hollow, generally cylindrical body. An annular V-shaped groove extends longitudinally within the cylindrical body from one axial end of the seal through approximately two-thirds of the length thereof. An annular bead is formed on the inner cylindrical surface of the seal adjacent the grooved axial end. The inner cylindrical surface extends generally parallel to the axis of the overall configuration of the seal. The outer cylindrical surface of the seal also extends parallel with the axis from the nongrooved axial end to a point along the length of the seal midway between the two axial ends. From this midpoint to the grooved axial end, the outer cylindrical surface diverges from the axis of the seal. When the seal is disposed about a rotatable shaft, the only friction between the two is generated along a circumferential contact line defined by the outer periphery of the annular bead. A pressure differential applied across the seal forces the sides of the groove apart and urges a substantial portion of the inner surface of the seal against the shaft so as to apply a braking force thereto. The fluid tightness of the seal is directly proportional to the pressure differential applied thereacross.

    Abstract: A constant plate area and spacing capacitance temperature probe for insertion into a fluid stream which is non-responsive to changes in pressure or content of the fluid investigated. Means for accommodating temperature induced changes in the dielectric fluid confined within the probe are provided internally of the interior of two concentric electrodes, the outermost of which serves to confine the dielectric fluid.

    CPC classification number: F16C39/063

    Abstract: An elongated magnetic rotor member supported by a magnetic bearing assembly in a conduit, the rotor having opposite ends with substantially conical tips which are supported by a magnetic field associated with the ends of the rotor and with spaced magnetic stator members. Each stator member includes a generally cup-shaped jewel that may be radially adjustable with respect to the longitudinal axis of the stator member. Each jewel provides a potential bearing surface for one of the rotor tips. The magnetic fields are longitudinally oriented, and are of such polarity that the tips of the rotor are drawn, in opposite directions, toward an adjacent jewel. The cup shape of the jewels provides lateral support for the rotor tip and aids in the centering thereof.
