摘要： A fluid for traction drives for automobiles which comprises (A) a hydrocarbon compound having two bridged rings selected from bicyclo[2.2.1]heptane ring, bicyclo[3.2.1]octane ring, bicyclo[3.3.0]octane ring and bicyclo[2.2.2]octane ring and (B) a hydrocarbon compound having at least one structure selected from quaternary carbon atom and ring structures and having a kinematic viscosity at 40°C of 10 mm 2 /s or smaller, and has a viscosity at -40°C of 40,000 Pa·s or smaller and a flash point of 140°C or higher, is provided. This fluid exhibits a great traction coefficient at high temperatures and very small viscosity at low temperatures. A fluid for traction drives which comprises a specific bicyclo[2,2,1]heptane derivative having 14 to 17 carbon atoms and having a viscosity index of 0 or greater is also provided. This fluid exhibits improved viscosity-temperature characteristics, decreased viscosity and improved fluidity at low temperatures.

摘要： The invention relates to stretched covering surfaces for walls and ceilings, consisting of a gridlike system of panels made of sheet-covered frames or stentering frames. Before the preferably rectangular frames are covered, they have side struts in the covering plane that curve in a slightly opposite direction to the direction of the covering. The amount of flexion increases from the corners outwards and is at its greatest in the middle between two corners. The amount of flexion is proportional to the height of the elastic pre-stress of the sheeting. In one specific embodiment, differences in the tensile strength of the sheeting in both a longitudinal and transversal direction are taken into account by the amount of flexion displayed by the side struts.
