Abstract
Abstract An apparatus for reclaiming lubricating oil which includes a housing having an evaporation plate dividing the housing into an evaporation chamber and a filter chamber, passages through the evaporation plate so filtered oil can flow into the evaporation chamber, a heater for heating the evaporation plate to cause volatile contaminants to leave the oil and an ultraviolet radiation source which directs sufficient radiation upon the oil to sterilize it.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
145 words
An apparatus for sterilizing and removing volatile impurities from lubricating oil comprising: (a) a container; (b) an evaporation plate positioned within said container, said evaporation plate defining the floor of an evaporation chamber within such container; (c) a plurality of passages passing through said evaporation plate from the base thereof to the top surface of said plate; (d) enclosure means for enclosing the top of the container and defining the top of said evaporation chamber; (e) means for heating the evaporation plate; and (f) an ultraviolet radiation source positioned above said evaporation plate and below said enclosure means, said ultraviolet radiation source being capable of directing sufficient radiation upon oil passing across the top of the evaporation plate to sterilize said oil; (g) vent means to permit vaporized materials to escape from said evaporation chamber, and means for conducting the oil from said evaporation chamber.
Claim 2
Independent Claim
