An improved control assembly is provided for supporting a helically coiled flexible conductor between two components that are movable relative to one another. The control assembly is slidably movable along a support rod in response to movement of one component relative to the other and is floatable upon the support rod to enable the control assembly to maintain proper alignment with the support rod along the length of the rod. In addition, as convolutions of the coiled conductor are discharged over a knob at the end of the control assembly, the control assembly is rotationally indexed around the support rod so that wear of the interior surface of the control assembly is evenly distributed around the internal bore of the control assembly.

An externally adjustable restriction control assembly for a poppet valve. The restriction control assembly is actuated through rotation of the valve stem. Upon rotation of the valve stem, a restriction control disc, threadably mounted to the valve stem guide, is moved toward or away from a seat provided within the housing. Movement of the restriction control disc thereby adjusts the effective cross-sectional flow area through the valve.

A brake assembly for impeding the longitudinal travel of a moving object. The brake asembly provides for a biasing mechanism which biases an engagement block into the line of travel of the moving object. When the moving object contacts the block, movement is impeded until the object is subjected to a force capable of deflecting the block counter to the biasing member and out of the line of travel of the object. The object can thereafter move past the said brake assembly and continuing along its line of travel. In particular, the brake assembly is used to impede the longitudinal travel of a reciprocating sootblower until the cleaning nozzles of the sootblower have had their position indexed relative to a previous cleaning cycle.
