  • Composite cross-over diffuser for a centrifugal pump, centrifugal pump comprising the same and corresponding manufacturing process
    Patent number: 12650131
    Abstract: The present disclosure concerns a composite diffuser for a centrifugal pump, the composite diffuser comprising a diffuser housing assembly at least partially delimiting an impeller shaft-receiving opening and having upstream and downstream sides, the diffuser housing assembly being at least partially formed in a first material; and a plurality of vanes mounted to or formed integral with the upstream side of the diffuser housing assembly and protruding therefrom, at least one of the plurality of vanes comprising a reinforcing vane portion formed in a second material different from the first material. It also concerns a centrifugal pump comprising such a composite diffuser, and a process for manufacturing a composite diffuser.

  • Signal leakage detector
    Patent number: 6980163
    Abstract: An antenna apparatus for detecting a leaked electromagnetic signal is provided. The apparatus includes a telescoping antenna and a casing, which has a portion of the antenna mounted in it. The antenna can move telescopically relative to the casing between an extended configuration, in which the antenna extends away from the casing, and a retracted configuration, in which the antenna is housed in the casing. A signal analyzer is located in the casing and is connected to the telescoping antenna. The antenna detects the electromagnetic signal, which is analyzed by the signal analyzer.
