Abstract
Abstract A portable degreaser comprising two concentric tanks separated by a perforated wall. The concentric tanks are an immersion tank located within a solvent-boiling tank which serves as an offsetvapor-generating sump. The rinse and spray area above the immersion tank is surrounded by a perforated wall. Boiling solvent is on the other side of the wall. Condensing coils encircle the perforated wall at the top of the spray area and thus, are exposed to the vapor an all sides. A gutter immediately below the condensing coils returns the condensed liquid into a separate distillate tank equipped with a water separator. The spray jets are supplied with the distilled solvent from the distillate tank. The distillate is kept hot since the lower portion of the tank is positioned within the boiling sump.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
A degreaser unit for degreasing articles of manufacture, said unit comprising an outer cabinet, said cabinet having therein a vapor-generating tank for converting liquid solvent into vapor, heating means associated with said vapor-generating tank to provide the heat to cause said solvent to boil and provide vapor, means for condensing said vapor to prevent the vapor from leaving said degreaser unit, immersion tank means located within said vapor-generating tank, said immersion tank means being surrounded on all sides by the solvent in said vapor-generating tank, and legs on said immersion tank to keep the bottom of said immersion tank separated from said heating means to thereby keep the solvent within said immersion tank from boiling.
Claim 2
Dependent Claim
115 words
A degreaser unit for degreasing articles of manufacture, said unit comprising an outer cabinet, said cabinet having therein a vapor-generating tank for converting liquid solvent into vapor, heating means associated with said vapor-generating tank to provide the heat to cause said solvent to boil and provide vapor, means for condensing said vapor to prevent the vapor from leaving said degreaser unit, immersion tank means located within said vapor-generating tank, said immersion tank means being surrounded on all sides by the solvent in said vapor-generating tank, and legs on said immersion tank to keep the bottom of said immersion tank separated from said heating means to thereby keep the solvent within said immersion tank from boiling.
Claim 3
Dependent Claim
31 words
The degreaser unit of claim 1, wherein a rinse and spray area is provided above said immersion tank, and wherein said rinse and spray area is surrounded by perforated wall means.
Claim 4
Dependent Claim
143 words
A degreaser unit for degreasing articles of manufacture, said units comprising an outer cabinet, said cabinet having therein a vapor-generating tank for converting liquid solvent to vapor, heating means associated with said vapor-generating tank to provide the heat to cause the solvent to provide vapor, means for condensing said vapor to prevent the vapor from leaving said degreaser unit, immersion tank means located within said vapor-generating tank, legs on said immersion tank to keep the bottom of said immersion tank separated from said heating means to thereby prevent the solvent within said immersion tank from boiling, a rinse and spray area located above said immersion tank, said rinse and spray area being surrounded by perforated wall means, and said means for condensing said vapors comprising refrigerate coils attached to said perforated wall means, thereby maximizing exposure of said coil means to the vapor.
Claim 5
Dependent Claim
143 words
A degreaser unit for degreasing articles of manufacture, said units comprising an outer cabinet, said cabinet having therein a vapor-generating tank for converting liquid solvent to vapor, heating means associated with said vapor-generating tank to provide the heat to cause the solvent to provide vapor, means for condensing said vapor to prevent the vapor from leaving said degreaser unit, immersion tank means located within said vapor-generating tank, legs on said immersion tank to keep the bottom of said immersion tank separated from said heating means to thereby prevent the solvent within said immersion tank from boiling, a rinse and spray area located above said immersion tank, said rinse and spray area being surrounded by perforated wall means, and said means for condensing said vapors comprising refrigerate coils attached to said perforated wall means, thereby maximizing exposure of said coil means to the vapor.
Claim 6
Dependent Claim
68 words
The degreaser unit of claim 3 wherein gutter means are provided below said coil means to trap solvent condensed by said coil means, and reserve distillate tank means for receiving said condensed solvent, spray jet means in said spray and rinse area, and means for passing said condensed solvent from said reserve distillate tank through said spray jet means under pressure to provide a spray of condensed solvent.
Claim 7
Dependent Claim
26 words
The degreaser unit of claim 4 wherein the distillate tank is so positioned as to be partly submerged within the liquid solvent in the vapor-generating tank.
Claim 8
Dependent Claim
24 words
The degreaser unit of claim 5 wherein said reserve distillate tank is provided with water separator means to assure a spray of pure solvent.
Claim 9
Dependent Claim
22 words
The degreaser unit of claim 6, wherein level indicator means are provided to indicate the level of solvent in said vapor-generating tank.
Claim 10
Dependent Claim
46 words
The degreaser unit of claim 7 wherein said perforated wall means is located and held between said immersion tank and a freeboard section, and flange means on said freeboard section whereby said freeboard section rests on the top of said cabinet at an article insertion opening.
