Abstract: A shaped part comprises a decorative layer on a shaped-part front side, which is configured as the visible face, and a carrier on a shaped-part reverse side. The shaped-part front side is subdivided into at least two regions, a first region and a second region. The decorative layer comprises a first decorative material and a second decorative material, each having a front side and a reverse side. In the first region, the front side the first decorative material provides part of the visible face, and in the second region, the front side of the second decorative material provides part of the visible face. The method comprises preshaping the first and second decorative materials, placing the preshaped decorative materials into an opened cavity of an injection mold, closing the cavity, and configuring the carrier by injecting plastics material into the cavity.

Abstract: A method and apparatus for determining leaks in sewage pipes. The apparatus includes a measuring probe having several radially arranged measuring electrode segments, the measuring probe being positioned in the sewage pipe. With the probe sections and electrode segments being arranged in such radial manner, the electrical probe, once electrically powered, measures a leakage current emitted by the probe's central section with several probes sections at a same electrical potential, and divides the measured leakage currents of the probe's central section in a mathematical operation into two or more electrode segments to determine both an axial and radial location for defects within the sewage pipe. A higher leakage current in one segment indicates the location of a leak, and the amplitude of the leakage current indicates the volume of the leak.

Abstract: A valve arrangement including a micro-valve at an intake opening and a fuer valve at an output opening of a chamber connecting to a pressure-variable switching member, the valves being structured to maintain a closed state by an applied pressure difference. At least the micro-valve is provided with a closure member which can be energized to affect a change-over from one state to another. No energy is required to maintain the changed-over state.
