    摘要： An angularly adjustable duct connector, intended primarily for high temperature air ducting systems for aircraft, having an internally disposed universal joint for mechanical connection between two ducts and an enclosing seal connection which permits angular displacement of the ducts and the seal connection being spaced therefrom to reduce exposure to heated air passing through the ducts.

    摘要： An earth dredger comprising a duct system for sucking up earth from a soil below water, the duct system comprising a plurality of rigid lengths of tube pivotally connected with each other by means of universal joints formed by hinge parts and coupling members and communicating with each other through flexible, elastic bellows is improved in that the coupling members of the universal joints are arranged between two adjacent bellows, so that the universal joint has smaller dimensions and the earth dredger is less expensive.
