Abstract: In a double twist spindle device wherein the support of the supply bobbin is retained against rotation on the spindle proper by two rows of permanent magnets disposed opposite each other each side of the radial passage of the yarn issuing from the axial bore of the spindle, one of the said rows is mounted in such manner as to be displaceable through a limited extent with respect to its supporting member. If the frictional torque between the spindle and the bobbin support temporarily reaches such an excessive value that the relative angular displacement of the rows becomes equal to the pitch of the successive magnets in both rows, the repulsive magnetic forces displace the said displaceable row in such manner that the undesirable accelerating effect of the magnetic forces on the bobbin support is eliminated or at least strongly decreased and that the rows may again find a new state of equilibrium when the excessive frictional torque disappears.

Abstract: A process for the efficient production of power from non-gaseous carbonaceous fuels, such as coal, or heavy fuel oil, in a steam power plant in which the carbonaceous fuel is first gasified at relatively high pressure and temperature by partial oxidation with oxygen to produce a fuel gas, the fuel gas from the partial oxidation reaction is expanded to a lower pressure in a turbine. Undesirable compounds, e.g., sulfur compounds, are removed from the fuel gas, and the fuel gas supplied to a steam boiler for the production of power.The process of this invention provides an effective means for conversion of gas-fired steam generation facilities to coal or heavy fuel oil while at the same time increasing the power generating capacity of the installation, all with minimal atmospheric pollution. The process is effective for the conversion of other types of gas-fired heaters and boilers to coal or heavy fuel oil.
