The invention relates to a composition, in particular a pulverulent master batch, comprising at least one nanoclay composed of a swellable inorganic layered material which has been modified by at least one siloxane component and by at least one non-anionic organic compound which has at least one aliphatic or cyclic radical having from 6 to 32 carbon atoms. The pushing device has a slide and an elastic component. A large number of modules can be arranged in a two-dimensional or three-dimensional stack with adjacent lines or planes of modules electrically interrelated by end segment connectors. It also coordinates transactions with multiple service providers as well as local resources on the device to facilitate electronic commerce transactions and deliver value added services. A signal is only output to a terminal corresponding to the current count number. The limited communication between the interior and exterior of the enclosure is kept substantially constant despite positioning movement of either the supporting surface or probes.
