Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
248 words
A soldering system comprising: a container for holding a supply of molten solder, said container including a first compartment for holding a portion of said solder supply at a first liquid solder level with a layer of oil floating of said solder therein, and a second compartment for holding another portion of said solder supply at a second liquid solder level above said first liquid level and with a layer of oil floating on said another portion of solder therein; a sump and nozzle positioned in said first compartment so that said sump is partially submerged when said supply of molten solder therein is at said first liquid level, said nozzle being disposed above the surface of said oil layer in said first compartment but below said second solder liquid level, first conduit means having an inlet disposed in said second compartment and communicating with said solder therein, and an outlet disposed in said sump for carrying a flow of molten solder between said second compartment and said sump and to overflow said nozzle; second conduit means having an inlet disposed in said second compartment and communicating with said oil therein, and an outlet disposed adjacent said nozzle for carrying a flow of oil between said second compartment for depositing on the top of said solder overflow; and means for transferring molten solder and oil from said first compartment into said second compartment so as to maintain said second liquid solder level and said layer of floating oil.
Claim 2
Dependent Claim
248 words
A soldering system comprising: a container for holding a supply of molten solder, said container including a first compartment for holding a portion of said solder supply at a first liquid solder level with a layer of oil floating of said solder therein, and a second compartment for holding another portion of said solder supply at a second liquid solder level above said first liquid level and with a layer of oil floating on said another portion of solder therein; a sump and nozzle positioned in said first compartment so that said sump is partially submerged when said supply of molten solder therein is at said first liquid level, said nozzle being disposed above the surface of said oil layer in said first compartment but below said second solder liquid level, first conduit means having an inlet disposed in said second compartment and communicating with said solder therein, and an outlet disposed in said sump for carrying a flow of molten solder between said second compartment and said sump and to overflow said nozzle; second conduit means having an inlet disposed in said second compartment and communicating with said oil therein, and an outlet disposed adjacent said nozzle for carrying a flow of oil between said second compartment for depositing on the top of said solder overflow; and means for transferring molten solder and oil from said first compartment into said second compartment so as to maintain said second liquid solder level and said layer of floating oil.
Claim 3
Dependent Claim
64 words
A soldering system as claimed in claim 1 wherein said means for transferring comprises: a pump, said pump having a first intake communicating with said solder in said first compartment, a second inlet communicating with said oil in said compartment and a common outlet; and third conduit means having an inlet communicating with said pump outlet, and an outlet disposed in said second compartment.
Claim 4
Dependent Claim
21 words
A soldering system as claimed in claim 2 wherein said first conduit outlet is disposed vertically above said third conduit inlet.
Claim 5
Dependent Claim
21 words
A soldering system as claimed in claim 2 wherein said second conduit inlet is disposed vertically above said first conduit outlet.
Claim 6
Dependent Claim
37 words
A soldering system as claimed in claim 1, and further including means for directing the overflow from said nozzle and said oil thereon below the surface of said portion of said solder supply in said first compartment.
Claim 7
Dependent Claim
63 words
A soldering system as claimed in claim 5 wherein said means for directing comprises an exterior sluice mounted on an exterior surface of said sump, said sluice adapted to conduct the overflow from said nozzle and said oil thereon through said layer of oil in said first compartment exterior of said sluice, and for discharging into said solder supply in said first compartment.
Claim 8
Dependent Claim
20 words
A soldering system as claimed in claim 6, and further including adjustable means for regulating the flow through said sluice.
