The present invention is directed to novel compounds according to formula wherein R1, R2, and X are as defined herein. The device includes a cylindrical body of given length and diameter, an eccentric weight rotating by a driving element within the cylindrical body, a handgrip coaxially extending to the cylindrical body, and a turbine mounted between the handgrip and the cylindrical body and forming the driving elements of the eccentric weight. A common alignment signal is manufactured that is based at least in part upon the GFC signal. Liquid hydrogen is supplied to the regions of low and high temperature heat transfer through inlet pipes.
