摘要： An essentially two-dimensional carrier member, plane or curved with respect to one or more axis outside said carrier member, is provided, as well as a plurality of closure elements. The carrier member is provided with a plurality of fluid passages and both the fluid passages and the closure elements are dimensioned and shaped in such a way that depending on whether said closure elements are inserted or removed, or depending in what axial position said closure elements are contained in said fluid passages fluid flow is free in both directions, blocked in one direction or blocked in both directions. The elements and/or the carrier member are at least in part of elastomeric material.

摘要： A reflecting element has at least one curved surface having a first plane of symmetry and being operative for reflecting incident light. A varying element is provided for varying the character of the reflector light and has a second symmetry paralleling the first plane. The elements are relatively moveable between an operative position and an inoperative position in which the varying element respectively varies and does not vary the character of light reflected by the reflecting element. An arrangement is provided for effecting such relative movement of the elements.
