Abstract
Abstract A method of and mixer block for feeding a stream of viscous material into a mixer employing not rotating parts is disclosed. The mixer block has a cavity therein terminating in an outlet which feeds the raid mixer. A first inlet is provided into the cavity at a point displaced from the outlet end for introduction of a first viscous material while a second inlet is provided between the first inlet and the outlet to introduce the second viscous material into the interior of the flow of the first viscous material thereby presenting a coaxial stream of viscous material to the said mixer.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
205 words
A mixer block for producing a stream of two or mOre viscous materials, comprising a mixing chamber in said mixing block, said mixing chamber being defined by an inner guiding wall in said block, said mixing chamber terminating in an opening at an outlet end; first inlet means for introducing a stream of a first viscous material into said mixing chamber, located at a point in said mixing block displaced from said outlet end; second inlet means for introducing a second viscous material into said mixing chamber, said second inlet means being located at a point in said mixing chamber between said first inlet means and said outlet end, a portion of said second inlet means extending into said mixing chamber; a check valve in communication with said portion of said second inlet means extending into said mixing chamber, said check valve extending into said mixing chamber and adapted to control the amount of and to introduce said second viscous material into the interior of said mixing chamber away from said guide wall thereof and into the interior of a stream of said first viscous material introduced via said first inlet means, thereby producing a coaxial linear flow of said first and second viscous materials.
Claim 2
Dependent Claim
205 words
A mixer block for producing a stream of two or mOre viscous materials, comprising a mixing chamber in said mixing block, said mixing chamber being defined by an inner guiding wall in said block, said mixing chamber terminating in an opening at an outlet end; first inlet means for introducing a stream of a first viscous material into said mixing chamber, located at a point in said mixing block displaced from said outlet end; second inlet means for introducing a second viscous material into said mixing chamber, said second inlet means being located at a point in said mixing chamber between said first inlet means and said outlet end, a portion of said second inlet means extending into said mixing chamber; a check valve in communication with said portion of said second inlet means extending into said mixing chamber, said check valve extending into said mixing chamber and adapted to control the amount of and to introduce said second viscous material into the interior of said mixing chamber away from said guide wall thereof and into the interior of a stream of said first viscous material introduced via said first inlet means, thereby producing a coaxial linear flow of said first and second viscous materials.
Claim 3
Dependent Claim
24 words
In combination with the mixer block as defined in claim 1: a mixer connected to said outlet end, said mixer employing no rotating parts.
Claim 4
Dependent Claim
89 words
In combination with a mixer block as defined in claim 1: first means for supplying said first viscous material to said first inlet means so that said first viscous material tends to fill said mixing chamber and flow towards said outlet end; second means for supplying said second viscous material to said second inlet means; said mixer block being further characterized in that said second viscous material is introduced into the interior of said mixing chamber so as to be surrounded by the flow of said first viscous material.
Claim 5
Dependent Claim
37 words
The combination as defined in claim 3 in which said first inlet means introduces a greater quantity of said first viscous material into said mixing chamber than said second inlet means introduces of said second viscous material.
Claim 6
Dependent Claim
40 words
The combination as defined in claim 4 in which said first viscous material flows to said outlet end along a path unencumbered by blocking surfaces so that said mixing chamber can be purged of said first and second viscous materials.
Claim 7
Dependent Claim
42 words
The combination as defined in claim 4 in which said first inlet means comprises an open pipe and purging means for purging said mixing chamber are selectively connected to said open pipe for feeding of purging materials therethrough into said mixing chamber.
Claim 8
Dependent Claim
19 words
The combination as defined in claim 6 in which said open pipe terminates flush with said inner guiding wall.
Claim 9
Dependent Claim
23 words
The method as defined in claim 1 wherein said first viscous material is surrounded in said combined stream by said second viscous material.
Claim 10
Independent Claim
105 words
A method of operating a mixer, which mixer employs no rotating parts, which comprises flowing a measured amount of a second viscous material into the interior of a stream of a measured amount of a first viscous material thereby establishing linear flow of said combined streams of first and second viscous materials; controlling the flow of said second viscous material into said stream of first viscous material, said control being effected immediately prior to the point at which said second viscous material flows into the interior of said first viscous material; and applying said combined stream of viscous material under linear flow to said mixer.
Claim 11
Independent Claim
105 words
A method of operating a mixer, which mixer employs no rotating parts, which comprises flowing a measured amount of a second viscous material into the interior of a stream of a measured amount of a first viscous material thereby establishing linear flow of said combined streams of first and second viscous materials; controlling the flow of said second viscous material into said stream of first viscous material, said control being effected immediately prior to the point at which said second viscous material flows into the interior of said first viscous material; and applying said combined stream of viscous material under linear flow to said mixer.
