Abstract: A geocomposite liner having a first fibrous layer, a second fibrous layer, and a non-fibrous layer secured between the first and second fibrous layers. A plurality of fibers extend from the non-fibrous layer such that the ends of the fibers extend outwardly of an outer surface of the first fibrous layer. The ends are heat fused so as to secure the ends outwardly of the outer surface of the first fibrous layer. The second fibrous layer is needle punched such that the fibers extend from the second fibrous layer through the non-fibrous layer. The ends of the fibers are heat fused such that the ends have a greater diameter exterior of the first fibrous layer than interior of the first fibrous layer. Some of the ends are heat fused together on the outer surface of the first fibrous layer.

Abstract: An internal-combustion engine comprises at least two inlet stroke valves per cylinder, the courses of the strokes of these stroke valves being adjustable in different manners. The adjustment takes place by means of an eccentric shaft which displaces the supporting point of a transfer element disposed between each cam and each stroke valve, in which case the two eccentrics assigned to one cylinder are of a different geometry. The transfer element is formed by a valve lever which is supported on the eccentric and is actuated by the cam, which valve lever, in turn, acts upon a rocker lever. The respective contact surfaces are formed by rollers. A further transfer element, which has a crank path, is also described.
