Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
185 words
A system for purifying continuously flowing liquids, said system comprising a closed container having an inlet and an outlet, ultraviolet ray-emission means of selected wave-length and intensity in said container, an ultraviolet light transmitting jacket surrounding said ray-emission emission means, wiper means for said jacket, hydraulic means connected to said wiper means for reciprocating said wiper means at predetermined periodic time intervals, a shutoff valve located adjacent said outlet, fail-safe monitoring means having a sensor and mounted on the exterior wall of said container, said sensor communicating with the interior of said container through a port thereof, said monitoring means for measuring the output of said ray-emission emission means and for activating devices for rendering said system fail-safe, power supply means mounted on said container adapted to supply electric energy for said ray-emission means, said valve, and said fail-safe monitoring means, said system being a compact unit through mounting of said monitoring means and said power supply on said container, and a timer in said power supply means for actuating at said predetermined periodic time intervals said power supply for reciprocatingly operating said wiper means.
Claim 2
Independent Claim
185 words
A system for purifying continuously flowing liquids, said system comprising a closed container having an inlet and an outlet, ultraviolet ray-emission means of selected wave-length and intensity in said container, an ultraviolet light transmitting jacket surrounding said ray-emission emission means, wiper means for said jacket, hydraulic means connected to said wiper means for reciprocating said wiper means at predetermined periodic time intervals, a shutoff valve located adjacent said outlet, fail-safe monitoring means having a sensor and mounted on the exterior wall of said container, said sensor communicating with the interior of said container through a port thereof, said monitoring means for measuring the output of said ray-emission emission means and for activating devices for rendering said system fail-safe, power supply means mounted on said container adapted to supply electric energy for said ray-emission means, said valve, and said fail-safe monitoring means, said system being a compact unit through mounting of said monitoring means and said power supply on said container, and a timer in said power supply means for actuating at said predetermined periodic time intervals said power supply for reciprocatingly operating said wiper means.
Claim 3
Dependent Claim
38 words
A system for purifying continuously flowing liquids according to claim 1, said monitoring means having means for controlling the shutting off of said valve when said output of said ray-emission emission means drops below a preset minimum level.
Claim 4
Dependent Claim
36 words
A system for purifying continuously flowing liquids according to claim 2, said monitor having means cooperating with said valve for permitting a warmup period of said ultraviolet ray-emission means before the liquid flows from said system.
Claim 5
Dependent Claim
22 words
A system for purifying continuously flowing liquids according to claim 3, said monitoring means also controlling the operation of said wiper means.
Claim 6
Dependent Claim
64 words
A system of purifying continuously flowing liquids according to claim 4, said wiper means comprising a wiper having a portion which slidably engages said jacket, said portion being chemically inert and unaffected by ultraviolet rays and a ring-shaped folding member for holding said portion, said portion being ring-shaped and held by said holding member along a diameter greater than the interval of said portion.
Claim 7
Independent Claim
151 words
A system for purifying continuously flowing liquids, said system comprising a plurality of units connected in series, each of said units comprising a closed container, one of said containers having an outlet, ultraviolet ray-emission means in said container, an ultraviolet light transmitting jacket surrounding said ray-emission means, wiper means for said jacket, hydraulic means connected to said wiper means for reciprocating said wiper means at predetermined periodic time intervals, a shutoff valve located adjacent said outlet, power supply means mounted on each said containers adapted to supply electric energy for said ray-emission means, and said valve, and fail-safe monitoring means having sensor means for said units, said monitoring means for measuring the output of said ray-emission means and for activating devices for rendering said system fail-safe, and a timer in said power supply means for actuating at said predetermined periodic time intervals said power supply for reciprocatingly operating said wiper means.
Claim 8
Independent Claim
151 words
A system for purifying continuously flowing liquids, said system comprising a plurality of units connected in series, each of said units comprising a closed container, one of said containers having an outlet, ultraviolet ray-emission means in said container, an ultraviolet light transmitting jacket surrounding said ray-emission means, wiper means for said jacket, hydraulic means connected to said wiper means for reciprocating said wiper means at predetermined periodic time intervals, a shutoff valve located adjacent said outlet, power supply means mounted on each said containers adapted to supply electric energy for said ray-emission means, and said valve, and fail-safe monitoring means having sensor means for said units, said monitoring means for measuring the output of said ray-emission means and for activating devices for rendering said system fail-safe, and a timer in said power supply means for actuating at said predetermined periodic time intervals said power supply for reciprocatingly operating said wiper means.
Claim 9
Dependent Claim
25 words
A system for purifying continuously flowing liquids according to claim 6, said system having a plurality of said series of said units connected in parallel.
Claim 10
Dependent Claim
28 words
A system for purifying continuously flowing liquids according to claim 7, wherein said parallely connected series are connected to a common inlet means and a common outlet means.
