Devices have been used to compensate for misalignment between adjacent members and establish subsequent aligned assembly. These devices used tight tolerance, compound eccentric bushings or offset frusto-conical surface in attempting to provide a fixed aligned position. These devices are expensive and difficult to align. The subject bolt-on dowel provides a simple inexpensive solution to positioning of a first member relative to a second member. The bolt-on dowel includes a cylindrical spacer slidably fitted within a bore of the first member with the first end being in abutment with the second member, and a fastening member securing the spacer to the second member in a fixed position.

A deaerator device has a tubular casing and an internal helical blade defines an axial opening through the center thereof toward which entrained gas bubbles will converge as a fluid travels through the casing. A vent pipe collects the gas bubbles at the opening and communicates them away from the casing.
