Abstract
Abstract A mixing-head assembly for a chemical ingredient treating system is provided characterized in that a shift from recirculation mode to feed-to-mixing-chamber mode of operation may be carried out by valve means which limits the possibility of leakage of chemical components, while metering-port construction, which permits variable flow control, also contributes to control of any possible leakage. Close control of mixing-chamber conditions is provided for by means which inhibits transfer of heat from the source of motive force to the mixing chamber, and means is provided for preventing undesired air pickup by the mixture in the mixing chamber.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
34 words
Chemical ingredient treating Apparatus as claimed in claim 1 wherein the material comprising one of said flat surfaces has a different coefficient of friction than the material comprising the other of said flat surfaces.
Claim 2
Dependent Claim
37 words
Chemical ingredient treating apparatus as claimed in claim 1 wherein the material comprising the flat surface in which said endless groove means occurs has a higher coefficient of friction than the material comprising the other flat surface.
Claim 3
Dependent Claim
128 words
Chemical ingredient treating apparatus as claimed in claim 1 wherein said openings in said closure plate means flat surface include a first opening terminating a chemical ingress passage, a second opening terminating a recirculation passage and a third opening terminating port means into said treating chamber, and one of said pairs of openings in said porting plate means flat surface terminates the ends of a subsurface passage for interconnecting said first and second openings when said porting plate is in position to direct said chemical ingredient into said recirculating means, and another of said pairs of openings terminates the ends of another subsurface passage for interconnecting said first and third openings when said porting plate means is in position to direct said chemical ingredient into said treating chamber.
Claim 4
Dependent Claim
71 words
Chemical ingredient treating apparatus as claimed in claim 4 wherein said first, second, and third openings constitute a group of openings in said closure plate means flat surface, and said one of said pairs of openings and said other of said pairs of openings constitute a group of pairs of openings in said porting plate means flat surface, there being a plurality of said groups in each of said flat surfaces.
Claim 5
Dependent Claim
75 words
Chemical ingredient treating apparatus as claimed in claim 4 wherein said openings in said closure plate means flat surface includes a fourth opening terminating a flushing agent ingress passage, and wherein still another of said pairs of openings in said porting plate means flat surface terminates the ends of a subsurface passage for interconnecting said third and fourth openings when said porting plate is in position to direct said chemical ingredient into said recirculating means.
Claim 6
Dependent Claim
48 words
Chemical ingredient treating apparatus as claimed in claim 6 wherein said endless groove means is in said porting plate flat surface and includes one endless groove encompassing said one of said pairs of openings therein, and another endless groove encompassing at least another of said pairs of openings.
Claim 7
Dependent Claim
44 words
Chemical ingredient treating apparatus as claimed in claim 7 wherein said endless groove encompassing said one of said pairs of openings therein encompasses also said second opening in said closure plate means flat surface when said porting plate is in either of said positions.
Claim 8
Dependent Claim
40 words
Chemical ingredient treating apparatus as claimed in claim 1 including rotatable mixing means in said treating chamber motor means for furnishing rotary power to said mixing means, and plastic gear means interposed between said motor means and said treating chamber.
Claim 9
Dependent Claim
59 words
Chemical ingredient treating apparatus as claimed in claim 9 wherein said plastic gear means is mounted for direct rotation by said motor means and including a drive shaft upon which sprocket means and said mixing means are mounted, said plastic gear means being disposed between said motor means and said treating chamber and in engagement with said sprocket means.
Claim 10
Dependent Claim
72 words
Chemical ingredient treating apparatus as claimed in claim 1 including internally threaded port means through said closure plate means opening into said treating chamber, a needle valve within said port means, said needle valve having a substantially rectangular head portion and a tapered body portion, and externally threaded sleeve means within said internally threaded port means whereby an access opening to said treating chamber is provided which is continuously variable in size.
Claim 11
Dependent Claim
37 words
Chemical ingredient treating apparatus as claimed in claim 11 wherein said closure plate means is of meTal and said externally threaded sleeve means is of plastic having a coefficient of friction lesser than that of said metal.
Claim 12
Dependent Claim
51 words
Chemical ingredient treating apparatus as claimed in claim 1 including rotatable mixing means in said treating chamber, an egress opening from said treating chamber, and an upwardly inclining surface adjacent said egress opening whereby mixed material must pass upwardly to reach said egress opening before being emitted from said treating chamber.
Claim 13
Dependent Claim
25 words
Chemical ingredient treating apparatus as claimed in claim 13 including removable nozzle means, said upwardly inclining surface being a part of said removable nozzle means.
Claim 14
Dependent Claim
77 words
Chemical ingredient treating apparatus including: a. means for recirculating a chemical ingredient; b. a chemical mixing chamber; c. mixing means in said mixing chamber; d. drive means for said mixing means; e. motor means to furnish rotary power for said drive means; and f. plastic gear means driven by said motor means, said plastic gear means being in engagement with said drive means for said mixing means and disposed between said mixing chamber and said motor means.
Claim 15
Dependent Claim
32 words
Chemical ingredient treating apparatus as claimed in claim 15 wherein said drive means includes a drive shaft and a sprocket mounted thereon, said plastic gear means being in engagement with said sprocket.
Claim 16
Dependent Claim
103 words
Chemical ingredient treating apparatus including: a. a chemical mixing chamber having a wall; b. mixing means in said mixing chamber; and c. an internally threaded port in said mixing chamber wall opening into said mixing chamber; a needle valve within said port means having: a head portion of lesser areal dimension than that of said port means, whereby a chemical ingredient may pass said head portion to enter said port; a tapered body portion within said port; and externally threaded sleeve means within said internally threaded port, whereby an access opening to said treating chamber is provided which is continuously variable in size.
Claim 17
Dependent Claim
34 words
Chemical ingredient treating apparatus as claimed in claim 17 wherein said chemical mixing chamber is metal and said sleeve means is of plastic having a coefficient of friction lesser than that of said metal.
Claim 18
Dependent Claim
68 words
Chemical ingredient treating apparatus including: a. a chemical mixing chamber; b. mixing means in said mixing chamber; c. drive means for said mixing means; d. egress means from said mixing chamber; and e. removable nozzle means having an upwardly inclined surface extending into said mixing chamber adjacent said egress means, whereby mixed material must pass upwardly to reach said egress opening before being emitted from said mixing chamber.
