Title: Walter A. Hartl: Innovator in X-ray Technology
Introduction
Walter A. Hartl is a prominent inventor based in Hamburg, Germany. He has made significant contributions to the field of X-ray technology, holding a total of 7 patents. His innovative designs have advanced the functionality and efficiency of X-ray tubes, making them more effective for various applications.
Latest Patents
One of Hartl's latest patents is for a rotary anode X-ray tube featuring a sliding bearing. This invention relates to a rotary anode X-ray tube that incorporates a sliding bearing along with a secondary bearing system. The secondary bearing system, preferably a magnetic bearing, is designed to absorb the majority of axial and radial bearing forces. The sliding bearing, which is ideally a spiral groove bearing with liquid metal lubrication, is configured to handle only a small fraction of the bearing forces. This design results in low friction while allowing for effective cooling of the anode disk and the supply of anode current.
Another notable patent by Hartl is for an X-ray tube that includes at least a partially metal housing and an electrode. This electrode can be connected to a positive high voltage and is mounted on a ceramic insulator portion. The design features a conical insulator portion enclosed by a wall portion, with at least the inner surface providing insulation. Additionally, a screening sleeve electrically shields the connection between the insulator portion and the electrode, projecting into a recess in the wall portion.
