  • Publication number: 20250207666
    Abstract: An assembly configuration prevents eddy or other electrical currents from flowing through the bearings that support relative motion of two components by incorporation of a sealing element that includes an electrically conductive additive material, thereby providing a conductive pathway to shunt the electrical currents externally from the bearings or around the bearings. The sealing element is therefore a two-function sealing element that seals the system components and additionally shunts the electrical currents externally from or around the bearings to prevent current flow through the bearings. A material of the contacting sealing element is electrically conductive, and in this manner, the sealing element is sufficiently electrically conductive to provide an electrically conductive path between the two components to shunt the eddy currents around the bearings.

  • Patent number: 12332642
    Abstract: A fault tolerant interface includes a sensor and a safety control that are electrically connected to each other by a single wire. The sensor is configured to provide various signals to the safety control dependent on environmental parameters. Based on the ignal received by the safety control, the fault tolerant interface may act accordingly and place the overall system in a mitigative state in the event of a fault state or an alarm state. Data and fault or alarm states are detected by determining a first time interval between a first edge and a second edge of a signal, wherein an edge is one of a transition of the signal from a first voltage to a second voltage or a transition of the signal from the second voltage to the first voltage on a single wire. Data values versus fault or alarm states are assigned based on whether a current time interval corresponds to the first time interval or the second time interval, or another time interval associated with alarm or fault states.

  • Publication number: 20250179999
    Abstract: A pump system including a prevention mechanism for preventing excessive fluid temperature buildup of system fluid. The overheat prevention mechanism includes a thermally-responsive control component made with a thermally-responsive material. The thermally-responsive control component is located in the pump system such that the thermally-responsive material is in thermal communication with the system fluid for effecting a change in temperature of the thermally-responsive material. The thermally-responsive material is configured to have an activation temperature that is a predefined amount less than a maximum operating temperature of the system fluid. The thermally-responsive control component is configured to cooperate with a pump control mechanism in the system to decrease pump output pressure in response to the thermally-responsive material being heated by the fluid to a temperature that is equal to or greater than the activation temperature of the thermally-responsive material.

  • Patent number: 12313173
    Abstract: An enhanced low noise relief valve renders the anodizing processing irrelevant to the low leakage nature of the valve member based on the tolerance between the tube portion of the valve member and the inlet bore of the machined housing. This is accomplished by providing an additional valve stem holder that acts as a stem holder through which at least part of the tube portion of the valve member extends, with the stem holder instead of the valve member tube being located adjacent to the bore of the machined housing. The stem holder does not need to be subject to the anodizing process, and therefore a tight tolerance between the valve member and stem holder provides adequate leakage control, and the anodizing process applied to the machined housing otherwise is separated from the location where leakage tolerance is critical.
