The invention relates to an assembly and structure for exerting a constant force on a pivot pin supporting a movable component of a hinge for elevating the axis about which the movable component pivots. The movable component connected between the pivot pin and a cover, so elevated and maintained elevated during operative movements of the cover, permits movements of the cover in opening and closing the entry through a nozzle of a reactor, particularly a glass-lined reactor, into the interior in a manner whereby any gasket or sealing structure disposed either around the cover or the nozzle may be protected from damage. The invention, also, relates to structure for mounting the assembly and structure, which may include additional structure for assist in opening and closing the cover, to a stationary component of the hinge.
