A logically operating safety gear can all of a sudden function completely erratic. This article explains the behaviour of friction, the effect of friction tolerances, why erratic behaviour occurs and what can be done to prevent erratic behaviour. This paper also explains the behaviour of triggering devices such as overspeed governors, and how their operation can effect safety gear operation. The natural behaviour of safety gears and overspeed governors is often not properly understood resulting in wrong safety gear/overspeed governor combinations.
Four years of work and investments of 175 million euros were required to erect additions to the publishing company’s two existing high-rise buildings. The Axel Springer Passage, the Ullstein Hall event center and a new main entryway were constructed following plans drafted by London architects Renton, Howard, Wood, Levin Partnership (RHWL). The Axel Springer Passage was erected on the plot on the Kochstrasse which had formerly been occupied by the printing plant. Now available at the center of Berlin’s historical newspaper district are high-quality office facilities, a diversity of services for the modern urban dweller and a variety of restaurants.
