A liquid hydrocarbon slug-containing vessel for incorporation into a system integrating a low-pressure separator with a vapor recovery process system, and a method for regulating the temperature of a gas to be compressed by a two stage compressor so as to prevent liquification of the gas and to prevent over-heating of the compressor. A flexible portion of the functional main body part of the molding is compressed and forced into a substantially C-shaped decorative or ornamental cover part, such as a substantially non-flexible metal cover part of a belt-line window molding for a motor vehicle, the flexible and elastic properties of the flexible main body part facilitating an assembly process. The manner of operation of the transducers is adjusted for one of the types of data to thereby cause the transducers to generate modified data for the one type of data. Additional high efficiency synthetic methods that utilize novel intermediates as well as the synthesis of these intermediates are also provided. Each multilayer can be about 5-10 \u03bcm thick.
