Abstract: The switching arrangement is a component of a line trunk group for subscriber and junction lines. It is associated with a test module which is located in a line loop, the two parts of which are connected to the switching arrangement in the form of test multiplex lines, in the same manner as voice multiplex lines associated with the subscriber and junction lines.

Inventor: KREUTER PETER DR ING
IPC: F01L9/20
Filed: 1989-06-27
Abstract: In an electromagnetic positioning device operating according to the principle of the spring-mass oscillator (12,18,5,20), in particular for actuating control valves in displacement machines, the working stroke of the control element can be varied by changing the position of the pole face of a working magnet (2) and the foot point (11) of one or more springs of the spring system. For this purpose, a magnetic control system serves to simultaneously change the spacing of the pole faces and to adapt the centre of oscillation to the new position of the pole faces by changing the position of one or more spring foot points. In addition, with this control system the magnetic resistance of one or more working magnets can also be changed.

Date Apr. 18, 1991.In the case of earth coverings made from concrete paving slabs, the noise generated by rolling traffic is disadvantageous. In order to reduce the generation of noise, plate-shaped concrete blocks exhibiting a significantly larger format than traditional paving slabs are proposed. The top side of the concrete blocks consists of a sound absorption layer (13) of porous concrete. On the bottom side, the concrete block is curved inwards, so that the fringe areas are subjected to a higher load. This results in a stable situation. For the purpose of draining off the surface water, the concrete block is equipped at the sides with upright slots (16), which adjoin the absorption layer (13) of porous concrete.
