A matrix in a rotating rotor prevents or inhibits formation of waves in a liquid ring. The matrix may be located in first and/or second channel sections defined by the rotor, liquid passing from the first to the second channel section; and a turbine may have a scoop removing liquid from the second section, proximate ends of barriers defined by the matrix. The matrix includes grooves between the barriers to communicate liquid generally parallel to an axis defined by the rotor. The grooves have end openings and may be closed in a direction toward that axis.

An inexpensive, lightweight reflective assembly member having good optical quality is provided. The reflective assembly is particularly adaptable to accommodating temperature variations without providing destructive thermal stresses and reflective slope errors. The reflective assembly may consist of a thin lamina reflective surface member and a lightweight substrate member of cellular structure. The respective materials may be chosen so that the coefficient of thermal expansion will be approximately the same. The substrate can comprise a cellular glass block while the reflective lamina member can be a thin sheet of glass with appropriate reflective coating. The lamina and cellular substrate member can be bonded together to form the reflective assembly. The method of fabrication includes abrading the cellular substrate with an abrasive master die to form an appropriate concave surface. An adhesive can be applied to the abraded surface and a lamina reflective surface can be placed under a uniform pressure to conform the reflective surface onto the desired abraded surface of the substrate.
