  • Lubricant reservoir system
    Patent number: 10962130
    Abstract: A lubricant reservoir system includes a lubricant reservoir having an interior wall and an inlet for receiving lubricant from a supply. A follower device in the reservoir contacts the interior wall of the reservoir in a sliding and sealing manner, and the follower device is movable up and down in the reservoir from a first position to a second position in response to a changing lubricant level. A valve is in fluid communication with the inlet and is configured to selectively prevent a flow of the lubricant through the inlet. A connector operatively connects the follower device to the valve unit such that the flow of the lubricant through the inlet is prevented when the follower device is in the second position. The connector is configured such that the valve is positionable independently of the reservoir.

  • Method and system of condition monitoring
    Patent number: 10962521
    Abstract: A condition monitoring system that determines a presence of change of water content in grease. The system provides a sensor electrode that is placed in the space where the grease is located. The electrode is suitably a plate with a surface area creating a capacitance C. This in combination with a resistor R, creates an RC circuit. The system senses the RC circuit. The dielectric constant of the monitored grease varies in dependence of the water content of the grease. A change of the dielectric constant will change RC, that is then sensed by the system. An analysis of a change of RC will determine if there is a presence of a change of the level of water content in the monitored grease.

  • Magnetic bearing assembly
    Patent number: 10955001
    Abstract: A radial magnetic bearing assembly having an unsymmetrical stator. The assembly comprises fewer or smaller electromagnets, and thus capacity, in the two lower quadrants below the rotor in use, in comparison to the electromagnets, and thus capacity, in the two upper quadrants above the rotor in use. This creates space in the two lower quadrants that can advantageously be used to move for example instrumentation and cooling from other places of the assembly to make the bearing assembly compactor, and also to be able to put instrumentation and cooling where it is best needed, close to the rotor.
