Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
14 words
A method as claimed in claim 1 wherein the diluent fluid is a liquid.
Claim 2
Dependent Claim
32 words
A method as claimed in claim 1 including the preliminary step of opening the container of the chemical substance by means of an opening device combined with a support for the container.
Claim 3
Dependent Claim
38 words
A method as claimed in claim 3 wherein the opening device comprises a fixed cutter having at least one sharp point and the step of opening the container is carried out by impaling the container upon the cutter.
Claim 4
Independent Claim
113 words
A method for combining a concentrated non-gaseous chemical substance with a diluent fluid comprising directing a predetermined measured amount of diluent fluid in at least one stream into a container containing only a predetermined amount of the chemical substance so as to wash the chemical substance from the container and thereby emptying the container while accomplishing a dilution and combination of the chemical substance with the diluent fluid in desired proportions wherein the container is supported in a substantially enclosed receptacle and positioned with a container opening facing downwardly before the diluent fluid is directed into the container, the diluent fluid being directed upwardly into the container to wash the chemical substance therefrom.
Claim 5
Dependent Claim
24 words
A method as claimed in claim 1 including the additional step of collecting the combined chemical substance and diluent fluid in a second container.
Claim 6
Dependent Claim
21 words
A method as claimed in claim 6 including the additional step of mechanically agitating the combined chemical substance and diluent fluid.
Claim 7
Dependent Claim
28 words
A method as claimed in claim 1 wherein the diluent fluid is directed into a plurality of containers of chemical substances to be combined with the diluent fluid.
Claim 8
Independent Claim
114 words
An apparatus comprising a feed receptacle for receiving a container containing only a concentrated chemical substance Which is to be emptied and combined with a diluent fluid, said receptacle having a first opening for receiving said container and a second opening through which the container contents are to be removed, said second opening being a downward facing opening, means within said receptacle for producing an opening only in the downward facing wall of said container, and means for directing a stream of fluid diluent upwardly into said container through said container opening for removing the contents thereof through said container opening and for washing the contents away by gravity through said second receptacle opening.
Claim 9
Dependent Claim
27 words
Apparatus as defined in claim 9 wherein said means for producing an opening in said container is a fixed cutter element upon which the container is impaled.
Claim 10
Dependent Claim
42 words
Apparatus as defined in claim 10 and including a supporting plate interiorly of said receptacle for supporting said container and having a central opening therein comprising said second opening, and wherein said cutter element is a portion of said plate struck therefrom.
Claim 11
Dependent Claim
21 words
Apparatus as defined in claim 9 and including control means for automatically regulating the amount of diluent directed into said container.
Claim 12
Dependent Claim
30 words
Apparatus as claimed in claim 9 wherein there is provided a closure for said first opening to prevent the escape of the contents of said container and said fluid diluent.
Claim 13
Independent Claim
147 words
An apparatus comprising a feed receptacle for receiving a plurality of containers the contents of which are to be emptied and combined with a diluent fluid, said receptacle having a first opening for receiving said containers and a second opening through which the containers'' contents are to be removed, means within said receptacle for producing downwardly facing openings in said containers, and means for directing a stream of fluid diluent into said containers through said containers'' openings for removing the contents thereof through said container opening and for washing the contents away through said second receptacle opening wherein said feed receptacle is operable to receive a plurality of containers the contents of which are to be combined with the diluent fluid, said receptacle having means within said receptacle for opening all of said containers and means for directing streams of fluid diluent into all of said containers.
Claim 14
Dependent Claim
29 words
Apparatus as claimed in claim 14 wherein said means for opening said containers comprises at least one fixed cutter element for each container upon which said containers are impaled.
Claim 15
Dependent Claim
106 words
A mixing apparatus comprising a tank for receiving ingredients to be mixed, agitating means in said tank, a dispensing apparatus mounted on said tank comprising a feed receptacle for receiving a container containing only a concentrated chemical substance which is to be removed and mixed with a diluent in said tank, said receptacle having a downward facing opening connecting the interior of said receptacle with the interior of said tank, means for directing jets of liquid diluent upwardly into an opening in the downward facing wall of said container to wash the entire contents therefrom by gravity through said opening and into said tank for mixing.
Claim 16
Dependent Claim
16 words
Apparatus as defined in claim 16 including cutter means in said receptacle for opening said container.
Claim 17
Dependent Claim
20 words
Apparatus as defined in claim 16 including control means for automatically regulating the amount of diluent injected into said receptacle.
Claim 18
Dependent Claim
22 words
The apparatus of claim 16 including a removable cover for said tank and wherein said dispensing apparatus is attached to said cover.
Claim 19
Dependent Claim
14 words
