A process for the fabrication of microvalve systems by thermoplastic molding and membrane techniques has been developed. The valve system consists of three individual valves formed by two parts molded from polymethylmethacrylate PMMA and a polyimide membrane. The mold inserts were manufactured by milling of a brass substrate using a 300fim diameter head. The three-dimensional microstructure of the inserts consists of fo,ur different levels for valve seats, orifices, alignment pins and cavities. The overall diameter and height of the whole valve system is 7mm and 1.9mm, respectively. The valves are designed to be normally open. To close the valves, the pressure in an actuator chamber above the membrane is raised by a heater coil and the membrane is pressed onto the valve seat. First measurements at a difference pressure of 1000 hPa showed a rate of water flow through a single valve of 171 PIS-'. An actuator pressure of 180 hPa was reached by heating air with a resistive heater and continuous electrical power of 158 mW. A valve supplied with nitrogen at 130 hPa was closed by an electrical power of 116mW.

Translation of the Bible or any other text unavoidably involves a determination about its meaning. There have been different views of meaning from ancient times up to the present, and a particularly Enlightenment and Modernist view is that the meaning of a text amounts to whatever the original author of the text intended it to be. This article analyzes the authorial-intent view of meaning in comparison with other models of literary and legal interpretation. Texts are anchors to interpretation but are subject to individualized interpretations. It is texts that are translated, not intentions. The challenge to the translator is to negotiate the meaning of a text and try to choose the most salient and appropriate interpretation as a basis for bringing the text to a new audience through translation.
