  • Publication number: 20250288926
    Abstract: A replaceable filter element includes an element material extending between first and second end caps of the replaceable filter element, and a support tube extending on an outside of the element material between the first and second end caps. The second end cap has, on a top face thereof, a flat contact surface which is radially delimited on an outside by a peripheral rim projecting axially towards the first end cap. The peripheral rim has on an inside a latching notch, to which a latching lug of the support tube is configured to be latched, to axially secure the support tube to the second end cap.

  • Publication number: 20050230553
    Abstract: An ice detector for providing a signal indicating ice formation includes a longitudinally extending probe protruding into an airflow. One or more surface roughness features on surfaces of the probe improve ice detection. Surface roughness features on the probe include ice accreting edges at a distal end of the probe and features arranged on a side surface of the probe which cause the airflow to increase in turbulence.

  • Publication number: 20050218268
    Abstract: An ice detector for providing a signal indicating ice formation includes a probe protruding into an airflow. The probe extends into the airflow from a strut. The strut has one or more features which allow the probe to accrete ice at a higher temperature than would conventionally be possible. Strut features can include a notch formed therein in an upwind direction relative to the probe, and a curved surface adjacent a point of extension of the probe from the strut.
