Abstract
Abstract A liquid-circulating device includes a vertical stack submerged in liquid and provided with a large bubble generator adjacent its bottom opening. The bubble generator comprises an open bottomed gas chamber and an inverted tubular siphon including a first vertical leg communicating with the upper part of the chamber, a second leg extending upwardly to a bubble discharge opening above the chamber, and a curved elbow located above the chamber opening. A tubular member is provided for guiding a cleaning tool into the siphon through one of its end openings. The chamber and siphon are enclosed in a casing with openings registering with the chamber opening and siphon discharge opening.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
126 words
A fluid-circulating device comprising, in combination with a vertically extending conduit having an upper discharge opening and a lower inlet opening submerged in said fluid, means submerged in said fluid for cyclically generating and delivering bubbles to said conduit below the top thereof and including a gas-accumulating chamber having an opening in the lower part thereof, a linearly extending tubular siphon member including a first upwardly extending tubular leg connected at the upper part thereof to said chamber and a second upwardly extending tubular leg horizontally spaced from said first leg and having an upper bubble discharge opening, and a curved tubular crossarm extending between the lower parts of said legs and positioned above said chamber opening, and means for pumping a gas into said chamber.
Claim 2
Dependent Claim
126 words
A fluid-circulating device comprising, in combination with a vertically extending conduit having an upper discharge opening and a lower inlet opening submerged in said fluid, means submerged in said fluid for cyclically generating and delivering bubbles to said conduit below the top thereof and including a gas-accumulating chamber having an opening in the lower part thereof, a linearly extending tubular siphon member including a first upwardly extending tubular leg connected at the upper part thereof to said chamber and a second upwardly extending tubular leg horizontally spaced from said first leg and having an upper bubble discharge opening, and a curved tubular crossarm extending between the lower parts of said legs and positioned above said chamber opening, and means for pumping a gas into said chamber.
Claim 3
Dependent Claim
17 words
The fluid-circulating device of claim 1 including means for guiding a cleaning tool into said siphon tube.
Claim 4
Dependent Claim
26 words
The fluid-circulating device of claim 2, wherein the cleaning tool guiding means comprise the conduit for the movement of gas from the pump into the chamber.
Claim 5
Dependent Claim
44 words
The fluid-circulating device of claim 1, wherein said siphon member terminates respectively in an inlet opening communicating with said chamber and an outlet opening defining said bubble discharge opening respectively, and means for guiding a cleaning tool into at least one of said openings.
Claim 6
Dependent Claim
26 words
The fluid-circulating device of claim 4 said tool guiding means comprising a guide tube directed toward one of said siphon member openings from the outside thereof.
Claim 7
Dependent Claim
55 words
The fluid-circulating device of claim 4, including a horizontal extending tubular leg connecting the upper part of said siphon first leg with said chamber, said tool guide comprising a pipe aligned with said horizontal tubular leg and communicating with said chamber at a point opposing said horizontally extending leg and connected to said gas-pumping means.
Claim 8
Dependent Claim
29 words
The fluid-circulating device of claim 4 said guide means comprising a vertically extending guide tube having a bottom opening adjacent and transversely offset relative to said siphon discharge opening.
Claim 9
Dependent Claim
43 words
The fluid-circulating device of claim 1, including a casing of greater transverse dimensions than and housing said chamber and siphon member, said casing having a bottom opening registering with said chamber bottom opening and a top opening registering with said siphon Discharge opening.
Claim 10
Dependent Claim
36 words
The fluid-circulating device of claim 8, wherein said casing is of cylindrical configuration, said chamber being transversely offset relative to the longitudinal axis of said casing, and said siphon discharge opening being coaxial with said casing.
Claim 11
Dependent Claim
