An apparatus for circulating and cooling a liquid lubricant utilized for lubricating an external device such as a mechanical seal. A housing has an internal lubricant reservoir and at least one peripheral outer sidewall with axially spaced and lower end wall portions in sealed relation with the peripheral outer sidewall. A cooling chamber is disposed about at least a portion of the internal reservoir and within the housing in communicating relation with the internal reservoir and is formed at least in part by the outer peripheral sidewall such that heat is transferable from within the chamber to an outside atmosphere. The apparatus also includes lubricant return means and feed means, the lubricant return means being at a level higher than the lubricant feed means such that lubricant which is returned from the mechanical seal to the cooling chamber flows downwardly therewithin -- by natural convection and gravity -- to the feed means so as to be directed back to the mechanical seal to provide further lubrication. Means for introducing a gaseous medium under elevated pressures into the reservoir serves to raise the level of the lubricant in the cooling chamber sufficiently to enable adequate heat transfer to take place through the peripheral outer sidewall and to insure a closed liquid loop which permits continuous convectional flow regardless of the level in the reservoir.

Breaks in the lining of a protectively lined reactor vessel are repaired without introducing unwanted electrical paths through the vessel. Specifically, the breaks are repaired using a plug comprising an insulated anchor stud anchored into the portion of the metal support wall underlying the break; a sealing gasket disposed on the portion of the protective lining surrounding the break; a washer disposed outside the sealing gasket; and a clamping arrangement mechanically coupling the washer and the anchor stud for clamping the gasket onto the protective lining throughout a path surrounding the break. In preferred embodiments, the insulating stud is a threaded cylindrical stud anchored into the wall by threading into a correspondingly threaded aperture, the sealing gasket is a corrosion-resistant, insulating plastic material such as a fluorocarbon, the washer is concave with respect to the gasket and filled with insulating cement, and the clamping arrangement is either a nut threadedly engaged to the insulating stud or a nut in combination with a second stud attached to the first. Reactor vessels using such repair plugs can utilize dip tubes of dissimilar metal without premature deterioration.
