  • Patent number: 11939253
    Abstract: The invention relates to a method for shaping a glass pane (1), wherein the glass pane (1) is first heated and then bent until it has reached a shape that corresponds to a predefined target contour (ks), wherein exterior forces act on the glass pane (1) for the purpose of bending the glass pane (1). A change in a local curvature of the glass pane (1) over time is controlled such that the surface of the glass pane (1) simultaneously achieves the target contour at all points of the surface that do not remain static, by setting a temperature, and thus a viscosity, of the glass pane (1) so as not to be constant as a function of the location during the bending operation, and/or by suitably setting forces transferred by mounts (6) and/or pressure forces transferred by one or more pressure strips (3). The application furthermore relates to multiple glazed units produced by the method.

  • Patent number: 11938045
    Abstract: Breathable residual-limb system that admits air and allows sweat to evaporate from the surface of the residual limb. In an embodiment, the system comprises a liner sock to be worn on the residual limb, and comprising air-permeable textile forming a substantially cylindrical portion that is closed on a distal end and open on a proximal end and comprising an internal surface and an external surface. The liner sock further comprises a friction-interface material that covers only a portion of the internal surface of the air-permeable textile, such that, when worn on the residual limb, the friction-interface material contacts a surface of the residual limb, and an uncovered portion of the air-permeable textile which the friction-interface material does not cover allows air to pass between an external environment of the liner sock and the surface of the residual limb.
