A method is disclosed for context-based communication in HTML pages in which embodiments include communications between readers of the HTML content and the creators of the HTML content. In particular, a mask can be formed on an isolation region that extends onto a portion of the substrate adjacent to the isolation region to provide a shielded portion of the substrate adjacent to the isolation region and an exposed portion of the substrate spaced apart from the isolation region having the shielded portion therebetween. The metal sheet has a bottom side which is compressed in immediate opposition to the profiled region to produce a compressed second region, while the profiled first region is produced. The motor is energized to operate at a certain speed. The tube is terminated at the top with an arrester for securing the displaceable means.
