An electronic circuit for a contactless tag includes a rectification circuit that rectifies an induced electromotive force caused by bringing an antenna coil into close proximity to a readerwriter to generate a rectified voltage and a secondary battery. The associated plant for the manufacture of the foamed or foamable polymer particles is provided with an apparatus for the processing of recycled, propellant-containing polymer particles. The system also includes an ink jet head assembly attached to a printer structure of the printer for printing a code or other information on the print medium. The hull also has good weight carrying ability at speed while not requiring excessive power. A rigid link is fixed to the door and extends inward to pass through a slot in the post.
