Abstract: A radiation and impact-protected radioactive waste cask, comprising a container for radioactive waste including an outer steel wall, an inner steel wall, a layer of lead located between the two steel walls, a steel base, a steel cover, a volume of quartz sand located inside the container, at least one internal vessel that is surrounded at least partially by the volume of quartz sand; and radioactive waste located inside the receptacle, wherein the radiation and impact-protected radioactive waste cask further comprises a removable outer transportation canister, wherein the removable outer transportation canister comprises a hollow cylindrical or polygonal body with a lower end and an upper end, configured for fittingly receiving therein the container for radioactive waste, wherein the lower end is closed by a fixed bottom and the upper is closed with a removable canister cover, wherein the hollow cylindrical or polygonal body, the fixed bottom and the removable canister cover are made of at least three layers,

Abstract: A double clutch assembly is provided in accordance with an embodiment. A pivot axis of a first lever and a pivot axis of a second lever is located at the same side of a first actuating element and of a second actuating element, namely at the same side of the tubular element and of the annular element. Furthermore, the first lever is provided with a first lever actuation area in form of the toe end area of the inner lever for a first actuator device, for example a piston. The first actuating element in form of the tubular element is situated in an area between the first lever actuation area and the pivot axis of the first lever.

Abstract: A clutch actuation device is provided for dual clutches of a Dual Clutch Transmission. The clutch actuation device includes, but is not limited to a cylinder assembly that is substantially fixed to a clutch casing. The cylinder assembly includes, but is not limited to an inner annular chamber, an outer annular chamber, an inner annular piston, and an outer annular piston. The inner annular chamber is intended for receiving liquid under pressure and includes, but is not limited to an inner inlet. Similarly, the outer annular chamber is intended for receiving liquid under pressure and includes, but is not limited to an outer inlet. The outer annular chamber surrounds a portion of the inner annular chamber. The inner annular piston is slidably disposed in the inner annular chamber for actuating a first clutch disc whilst the outer annular piston is slidably disposed in the outer annular chamber for actuating a second clutch disc.
