Abstract
Abstract An apparatus for cleaning filters and the like having a pair of containers in a side-by-side relationship, one of the containers having a liquid solvent heated to a predetermined temperature for cleaning filters submerged therein; the other container being a storage tank adapted to dispense a pressurized solution for spray rinsing the cleaned filters; the two containers having a common partition adapted to transfer heat from the liquid solvent holding container to the storage tank for maintaining the temperature of the rinsing solution at a value less than the predetermined temperature of the liquid solvent. In a second embodiment, a dip rinse container is disposed intermediate the liquid solvent holding container and the storage tank, the dip rinse container and the storage tank having the common partition for the transfer of heat to the storage tank while the liquid solvent holding container and the dip rinsing container utilize a common heating means.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
249 words
An apparatus for cleaning objects comprising: a container having two compartments, the first one of which is adapted to hold a liquid solvent for cleaning objects submerged therein; means associated with said one compartment for maintaining said liquid solvent at a predetermined temperature; the second compartment adapted to store a rinsing solution therein, said first and second compartments having partitions to transfer heat from said first compartment to said second compartment to maintain the temperature of said rinsing solution at a value less than said first-mentioned predetermined temperature; means connected with said second-mentioned compartment for forcibly spraying said objects with said rinsing solution upon removal of said objects from said liquid solvent; a third compartment having a rinsing solution therein, said third compartment being adapted to rinse said objects when submerged therein, said third compartment being positioned between said first- and second-mentioned compartments and having means associated therewith for maintaining said rinsing solution contained in said third compartment at substantially the same temperature as said liquid solvent, said second-mentioned and said third compartments having a common partition adapted to transfer heat from said third compartment, thereby maintaining the temperature of said second-mentioned compartment rinsing solution at a value less than the temperature of said liquid solvent; said means for maintaining said rinsing solution contained in said third compartment at said predetermined temperature comprises a heating conduit submerged in said first-mentioned compartment proximate the bottom portion of said first-mentioned compartment, and means for circulating the heated medium through said conduit.
Claim 2
Independent Claim
249 words
An apparatus for cleaning objects comprising: a container having two compartments, the first one of which is adapted to hold a liquid solvent for cleaning objects submerged therein; means associated with said one compartment for maintaining said liquid solvent at a predetermined temperature; the second compartment adapted to store a rinsing solution therein, said first and second compartments having partitions to transfer heat from said first compartment to said second compartment to maintain the temperature of said rinsing solution at a value less than said first-mentioned predetermined temperature; means connected with said second-mentioned compartment for forcibly spraying said objects with said rinsing solution upon removal of said objects from said liquid solvent; a third compartment having a rinsing solution therein, said third compartment being adapted to rinse said objects when submerged therein, said third compartment being positioned between said first- and second-mentioned compartments and having means associated therewith for maintaining said rinsing solution contained in said third compartment at substantially the same temperature as said liquid solvent, said second-mentioned and said third compartments having a common partition adapted to transfer heat from said third compartment, thereby maintaining the temperature of said second-mentioned compartment rinsing solution at a value less than the temperature of said liquid solvent; said means for maintaining said rinsing solution contained in said third compartment at said predetermined temperature comprises a heating conduit submerged in said first-mentioned compartment proximate the bottom portion of said first-mentioned compartment, and means for circulating the heated medium through said conduit.
Claim 3
Dependent Claim
23 words
The combination as defined in claim 1, wherein said second-mentioned compartment is enclosed and includes means for pressurizing the rinsing solution stored therein.
Claim 4
Dependent Claim
22 words
The combination as defined in claim 2, wherein said second-mentioned compartment is supplied with compressed air to maintaiN said rinsing solution pressurized.
Claim 5
Dependent Claim
19 words
The combination as defined in claim 1, including means associated with said first-mentioned compartment for agitating said liquid solvent.
Claim 6
Dependent Claim
48 words
The combination as defined in claim 4, wherein said agitating means comprises a perforated wall member disposed proximate the bottom portion of said first-mentioned compartment and means for introducing pressurized air through said perforated wall member whereby air is distributed through said liquid solvent to agitate the same.
Claim 7
Dependent Claim
47 words
The combination as defined in claim 5, wherein said perforated wall member is an elongated cylindrically shaped pipe having a plurality of axially spaced holes extending therethrough, said pressurized air being directed from the interior of said pipe through said holes and into said liquid-filled first-mentioned compartment.
Claim 8
Dependent Claim
26 words
The combination as defined in claim 1, including sensing means responsive to the temperature of said liquid solvent to control the circulation of said heated medium.
Claim 9
Dependent Claim
15 words
The combination as defined in claim 7, wherein said heated medium is a hot gas.
Claim 10
Dependent Claim
35 words
The combination as defined in claim 1, including sensing means responsive to temperature of said liquid solvent to control the circulation of said heated medium through said conduit passing through said first-mentioned and third compartments.
