  • Patent number: 10570769
    Abstract: A machine having a shaft with a stage having a first shaft section having a first diameter, a second shaft section having a second diameter that is shorter than the first, forming a radially extending rotatable shaft end surface; a housing; and a bearing supporting the shaft on the housing by its second shaft section, and lubricated by a lubrication fluid. A sealing chamber has a sealing fluid that prevents the lubrication from leaving the bearing, and is axially limited by the shaft end surface and bearing end side, and radially inwardly limited by the second shaft section released from the bearing. A radially extending and stationary separator plate is in the sealing chamber to achieve an aerodynamic shielding of the bearing end side from the shaft end surface. When the shaft is rotating, the region between the separator plate and the bearing end side is substantially non-rotational.

  • Patent number: 10550676
    Abstract: Systems and methods for determining proper phase rotation in a linear motor where the phase rotations associated with power and return strokes are initially unknown. Power having an initial phase rotation is provided to a linear motor until the motor's mover reaches the end of the stroke, and then power to the motor is discontinued. While power is discontinued, the mover is monitored to detect its movement. if the mover moves without power, the mover was at the top of the stroke, so the initial phase rotation is associated with an upward stroke of the mover, and a second phase rotation which is opposite the initial phase rotation is associated with a downward stroke of the mover. Otherwise, the initial phase rotation is associated with the downward stroke of the mover and the second, opposite phase rotation is associated with the upward stroke of the mover.

  • Patent number: 10539123
    Abstract: In situations where a vacuum system is suddenly overloaded, there is a risk of mechanical damage being sustained, for example, bearing damage, gear slippage or rotor and/or stator collisions. Sudden overloads can also lead to electrical damage, for example, over-currents or power surges. Therefore a pressure regulating apparatus is provided for use in a vacuum pumping system having an inlet, an outlet and a conduit interposed between, and in fluid communication with, the inlet and the outlet, wherein the cross-sectional area of the conduit is greater than that required to meet the conductance requirements of the inlet and the outlet.
