Lubricating oil reconditioning system with electrically heated platen

A lubricating oil reconditioning apparatus comprising in combination:

• a dome configured platen means having associated electrically actuated resistance heating means for heating said platen means;
• a housing structure which generally encloses said platen means and defines in cooperation therewith a chamber that overlies said platen means;
• said housing structure including cooperative interengaging means for passage of filtered oil from an input orifice defined into an upper portion of said housing structure into said housing structure for oil flow upon and over a portion of said platen means as a thin film with said platen means being heated so that gas produced from said thin film enters said chamber while oil that drains from said platen means is collected at a lower region of said chamber;
• and
• said housing structure further including associated first conduit means for receiving said collected oil and associated second conduit means for receiving said gas from said chamber;
• said housing structure having a top portion that includes both an upstanding central stud means which is axially apertured and that is threaded on at least terminal portions of outer circumferential regions, that as a circumferentially extending upraised ridge means located in radially spaced relationship to said stud means and that has a generally flattened outer surface portion;
• said stud means being threadably engagable with a threaded aperture means defined in a cooperating plate member, said cooperating plate member additionally having defined therein a circumferentially extending gasket supporting region and an associated gasket means,
• said gasket supporting region being in radially spaced relationship to said threaded aperture means with said gasket means being sealingly engagable with said flattened outer surface portion when said cooperating plate member is so engaged with said stud means.
