A machine and a method for assembling a vehicle body is disclosed as including a locating pin formed with a seating flange portion having a work seating surface and a clamp arm contained in the locating pin to be operable in a clamping or unclamping movement responsive to an extrusion and retraction of a clamp cylinder. The invention relates to a method for the operation of a variable speed wind turbine having pitch and torque control means that include additional steps for providing to the pitch control means in case of a wind gust a pitch angle reference increment D\u03b8ref in the amount needed for avoiding that the aerodynamic torque added by the wind gust exceeds a predetermined limit. A dielectric sleeve surrounds a portion of the RF conductor, the sleeve having an axial length along the RF conductor, a dielectric constant and an axial location along the RF conductor, the length, dielectric constant and location of the sleeve being such that the sleeve provides a reactance that enhances plasma ion density uniformity over the working surface. The sensor bracket is domed to securely anchor the seat to the floor bracket in the event of an inverse overload. A coupling nut is configured to mechanically secure the electrical connector to the mating connector.
