Abstract: A net, in particular a ball net for catching balls, such as a volleyball net, football net, tennis net or ball-catching net, or a net-like fence, has a net body formed from net threads connected to one another in mesh form. The net is distinguished in that the net. threads of the net body are thickened, in one region, over a plurality of meshes by an applied thickening material, in such a way that the region can be recognized by the observer outwardly, with high visual contrast, as a character, in particular as a letter character or logo.

Abstract: In an individual rotor blade control device for a helicopter main rotor with a rotor shaft that can be driven by a main drive, with an even number of rotor blades that are arranged on the periphery of a rotor hub, with primary control mechanisms for collective and sinusoidal, cyclic rotor blade adjustment, which include a transfer element for the control movements from a non-rotating system to a rotating system and with actuators that are individually allocated to the rotor blades, wherein the actuator control movement is superimposed onto the control movement of the primary control mechanisms and each actuator is equipped with a safety device in order to bring the actuator into its final position and keep it there, if necessary, it is suggested that the setting angle change of one half of the rotor blades have an opposed direction due to the securing of the actuators in their final positions, like the setting angle change of the other half of rotor blades, and that the rotor blades of each half be distribute

Abstract: The invention relates to a process and an apparatus for decomposing articles, especially contaminated articles, by means of a decomposition device. To make it possible to the use an easily manipulated decomposition device while avoiding bulky devices, and at the same time to enable in-situ decomposition, in the tightest possible space, in a way that suits packing needs, it is proposed that the decomposition device execute an oscillating motion such that as a function of the progress and/or duration of the decomposition of the article, a varying resultant of the direction of decomposition force introduced by the decomposition device is established.
