Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
210 words
Apparatus for use in dispensing a composition provided by the mixing together of at least two constituent compositions and comprising first storage means for containing a first of said contituent compositions, second storage means for containing a second of said constituent compositions, means for mixing constituent compositions, first and second cylindrical chambers of different diameters and having pistons slidable therein in one direction to feed one composition from the first storage means to the first chamber while the other composition is fed from the second chamber to the mixing device, said pistons being slidable in the opposite direction to reverse the actions of the chambers; correlating means comprising a pivoted member connected to the pistons and means connected to said member between the connections for said pistons for operating said member to operate the pistons alternately in said directions, the ratio of the distances between the respective connections for the pistons of the first and second chambers and the connection for the operating means being equal to the inverse ratio of the diameters of the respective first and second chambers, the relation of said connections to the pivot of said member being so arranged as to cause said pistons to feed a predetermined ratio of said first and second compositions.
Claim 2
Dependent Claim
210 words
Apparatus for use in dispensing a composition provided by the mixing together of at least two constituent compositions and comprising first storage means for containing a first of said contituent compositions, second storage means for containing a second of said constituent compositions, means for mixing constituent compositions, first and second cylindrical chambers of different diameters and having pistons slidable therein in one direction to feed one composition from the first storage means to the first chamber while the other composition is fed from the second chamber to the mixing device, said pistons being slidable in the opposite direction to reverse the actions of the chambers; correlating means comprising a pivoted member connected to the pistons and means connected to said member between the connections for said pistons for operating said member to operate the pistons alternately in said directions, the ratio of the distances between the respective connections for the pistons of the first and second chambers and the connection for the operating means being equal to the inverse ratio of the diameters of the respective first and second chambers, the relation of said connections to the pivot of said member being so arranged as to cause said pistons to feed a predetermined ratio of said first and second compositions.
Claim 3
Dependent Claim
45 words
Apparatus according to claim 1 including means to adjust the distance between said pivot and the connection of the operating means for varying the ratio of said first and second compositions fed by the pistons and maintaining constant the total quantity of the compositions fed.
Claim 4
Dependent Claim
38 words
Apparatus according to claim 2 including means to vary the extent of movement of said correlating member for varying the total quantity of the compositions fed and maintaining constant the ratio of the first and second quantities fed.
Claim 5
Dependent Claim
138 words
Apparatus for use in dispensing a composition provided by the mixing together of at least two constituent compositions and comprising first feeding means operable to feed a first of said constituent compositions and comprising a cylindrical chamber having a piston slidably disposed therein, second feeding means operable to feed a second of said constituent compositions and comprising a cylindrical chamber having a piston slidably disposed therein, said cylindrical chambers being of different diameters, correlating means controlling the operation of the first and second feeding means according to an operating ratio equal to the inverse ratio of the diameters of the first and second cylinders, said correlating means being adjustable for varying the effectiveness of said operating ratio to vary the ratio of the quantities of the compositions fed and maintaining constant the total quantity of the compositions fed.
Claim 6
Dependent Claim
138 words
Apparatus for use in dispensing a composition provided by the mixing together of at least two constituent compositions and comprising first feeding means operable to feed a first of said constituent compositions and comprising a cylindrical chamber having a piston slidably disposed therein, second feeding means operable to feed a second of said constituent compositions and comprising a cylindrical chamber having a piston slidably disposed therein, said cylindrical chambers being of different diameters, correlating means controlling the operation of the first and second feeding means according to an operating ratio equal to the inverse ratio of the diameters of the first and second cylinders, said correlating means being adjustable for varying the effectiveness of said operating ratio to vary the ratio of the quantities of the compositions fed and maintaining constant the total quantity of the compositions fed.
Claim 7
Dependent Claim
80 words
Apparatus as set forth in claim 4 wherein said correlating means comprises a pivoted member connected to the two pistons and further including operating means for moving said correlating member about its pivot and connected to said correlating member between said piston connections to said correlating member, the ratio of the distances between the connections of the first and second pistons and the operating means being equal to the inverse ratio of the diameters of the first and second chambers.
Claim 8
Dependent Claim
47 words
Apparatus according to claim 5 including means to adjust the distance between said pivot and the connection of the operating means for varying the ratio of the respective quantities fed by the first and second feedinG means and maintaining constant the total quantity of the compositions fed.
Claim 9
Dependent Claim
43 words
Apparatus according to claim 5 including means to vary the extent of movement of the correlating member for varying the total quantity of the compositions fed and maintaining constant the ratio of the respective quantities fed by the first and second feeding means.
