Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
Apparatus for introducing a material into a liquid comprising: a. means defining a first conduit suitable for transmitting said material therethrough; b. means defining a second conduit suitable for transMitting said liquid therethrough; c. means defining a flexible injection nozzle connected to said first conduit for injecting said material into said liquid, said injection nozzle being positioned in communication with said liquid so that said liquid can flow about and through said nozzle to cause said nozzle to undergo a flexing motion preventing the deposition of said material thereon; and d. valve means positioned in said first conduit upstream of said injection nozzle for preventing backflow of said liquid beyond said valve means.
Claim 2
Dependent Claim
113 words
Apparatus for introducing a material into a liquid comprising: a. means defining a first conduit suitable for transmitting said material therethrough; b. means defining a second conduit suitable for transMitting said liquid therethrough; c. means defining a flexible injection nozzle connected to said first conduit for injecting said material into said liquid, said injection nozzle being positioned in communication with said liquid so that said liquid can flow about and through said nozzle to cause said nozzle to undergo a flexing motion preventing the deposition of said material thereon; and d. valve means positioned in said first conduit upstream of said injection nozzle for preventing backflow of said liquid beyond said valve means.
Claim 3
Dependent Claim
78 words
The apparatus of claim 1 wherein: a. said second conduit means defines an enclosed passage having a substantially circular cross section and having an opening therein substantially perpendicular to said circular cross section; and b. said injection nozzle means is positioned and arranged in said opening so as to extend into said second conduit for communication with said liquid transmitted by said second conduit in an angular manner with respect to the longitudinal axis of said elongated nozzle.
Claim 4
Dependent Claim
28 words
The apparatus of claim 2 wherein said elongated injection nozzle is generally cylindrically shaped and extends angularly across substantially the entire circular cross section of said enclosed passage.
Claim 5
Dependent Claim
63 words
The apparatus of claim 3 wherein: a. said first conduit means defines an opening therein between said valve means and said injection nozzle; and b. said first conduit means includes a conduit connecting said second conduit means and said opening in said first conduit means for introducing a flow of said liquid into said first conduit so as to flush said injection nozzle.
Claim 6
Dependent Claim
70 words
The apparatus of claim 4 wherein: a. said liquid is substantially water; b. said material is substantially chlorine; c. said injection of said material and said flushing of said nozzle occur simultaneously; and d. said flexible injection nozzle is substantially comprised of a plastic material and defines a plurality of openings therein for exhausting said chlorine and for allowing said liquid to flow therethrough during said flushing of said nozzle.
Claim 7
Dependent Claim
73 words
The apparatus of claim 1 including reservoir means for containing a quantity of said liquid therein: a. said injection nozzle means is positioned substantially entirely within said reservoir means; b. said second conduit means is adapted to introduce said liquid into said reservoir means, said liquid introduced therein being directed onto said injection nozzle means at an angular direction with respect to the longitudinal axis of said elongated nozzle for causing deflection thereof.
Claim 8
Dependent Claim
54 words
The apparatus of claim 6 wherein: a. said reservoir is a substantially cylindrically shaped tank adapted to contain said liquid under pressure and having outlet means therein for exhausting said liquid and injected material; and b. said injection nozzle means is positioned in said tank substantially normal to the cylindrical walls of said tank.
Claim 9
Dependent Claim
63 words
The apparatus of claim 7 wherein: a. said first conduit means defines an opening therein between said valve means and said injection nozzle; and b. said first conduit means includes a conduit connecting said second conduit means and said opening in said first conduit means for introducing a flow of said liquid into said first conduit so as to flush said injection nozzle.
Claim 10
Dependent Claim
70 words
The apparatus of claim 8 wherein: a. said liquid is substantially chlorine; b. said material is substantially water; c. said injection of said material and said flushing of said nozzle occur simultaneously; and d. said flexible injection nozzle is composed substantially of a plastic material and defines a plurality of openings therein for exhausting said chlorine and for allowing said liquid to flow therethrough during said flushing of said nozzle.
