  • Patent number: 11039941
    Abstract: A prosthetic foot, comprising a core, on which a proximal fastening device for fastening the prosthetic foot to a lower-leg tube or to a lower-leg shaft is arranged and which is surrounded by a foot casing. The foot casing forms a cavity, in which the core is inserted. A slot-shaped recess is formed in a front foot region of the foot casing, into which slot-shaped recess a tongue arranged on the core is inserted. The front foot region has a stiffness that deviates in comparison with the rest of the foot casing.

  • Patent number: 6206943
    Abstract: An aircraft separator system for removing moisture suspended in a gas of an aircraft waste system includes a waste tank and a vacuum source operatively coupled to the waste tank for creating a vacuum for drawing the waste material into the tank and drawing the gas with the moisture suspended therein out of the tank. A disposable separator housing for removing moisture suspended in the gas is disposed on the tank and removably coupled between the waste tank and the vacuum source such that the entire separator housing may be detached from the waste tank and vacuum source and discarded. A two-stage filter is contained within an interior of the housing without extending into the waste tank. The filter has at least two areas of different density mesh defining two stages including a first area located proximal to a separator inlet opening which is less dense, and a second area located proximal to a separator outlet opening which is more dense.
