METHOD AND TESTING DEVICE FOR DETERMINING A STATE OF A SUSPENSION TRACTION APPARATUS OF AN ELEVATOR SYSTEM
A method for determining a state of an elevator system suspension traction apparatus having at least one electrically conductive cord with a first end and an opposite second end, the cord having a wave impedance. A signal generator is electrically connected to the cord first end and a terminating resistor having a first resistance value matched to the wave impedance of the cord is electrically connected to the cord second end. The method includes the steps: inputting an, in particular alternating, electrical excitation signal of the signal generator into the cord first end; at least one of measuring a reflection signal of the excitation signal at the cord first end, and measuring a transmitted signal of the excitation signal at the cord second end; and determining the state of the suspension traction apparatus by comparing the excitation signal with at least one of the reflection signal and the transmitted signal.
Aircraft Fuselage and Structural Cable for Aircraft Fuselage
A wide body aircraft is discussed having a fuselage with a first structural element, a second structural element, a wide-body fuselage section, and a plurality of tension members. Each of the first structural element and the second structural element may be arranged to traverse a longitudinal length of the wide-body fuselage section.

STEEL CORD WITH A BRASS COATING ENRICHED WITH IRON PARTICLES
A steel cord that is suitable for reinforcing rubber articles such as tires. The inventive steel cord enables to completely eliminate the presence of cobalt in a tire when combined with the proper cobalt free compound. Advantageously the steel cord adheres equally well to rubbers containing organic cobalt salts. The inventive wire is different from prior art steel cords in that the brass coating now comprises iron particles. The iron particles have a size between 10 nm and 10 000 nm. The presence of iron mitigates the adhesion retention loss of the rubber to steel cord bond in a hot and humid environment. It is a further advantage that the inventive steel cord does not contain any intentionally added cobalt thereby contributing to the elimination of harmful substances in the production area as well as the environment.
