Abstract
Abstract A motionless mixing device for mixing fluidic materials such as liquid, gas, wet and dry powders, etc. employing a generally horizontal cylindrical housing with an inlet at one end and an outlet at the opposite end. A plurality of spaced-apart mixing elements are positioned in the housing to form a mixing device, each of mixing elements being inclined transversely of the longitudinal axis of the housing at a linear edge thereof in the direction of the flow of the fluidic materials flowing through the housing, one end of each said mixing element in the radial direction of the housing being fixedly disposed in the inner wall of the housing, a suitable space being formed between another end of each said mixing element and the adjacent inner wall thereof so that materials trapped by said element are permitted to pass therethrough.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
134 words
A motionless mixing device, comprising a hollow cylindrical housing for introducing a plurality of fluidic materials and a plurality of mixing elements of circular cross-section fixedly positioned within the housing, each of said mixing elements being inclined transversely of the longitudinal axis of the housing at a linear edge thereof in the direction of the flow of fluidic materials through the housing, one end of each of said mixing element in the radial direction of the housing being fixedly disposed in the inner wall of the housing and extending across and through the longitudinal axis of said cylindrical housing, said mixing element further having a space formed between another end of each said mixing element and the adjacent inner wall thereof so that the materials trapped by said element are permitted to pass therethrough.
Claim 2
Dependent Claim
134 words
A motionless mixing device, comprising a hollow cylindrical housing for introducing a plurality of fluidic materials and a plurality of mixing elements of circular cross-section fixedly positioned within the housing, each of said mixing elements being inclined transversely of the longitudinal axis of the housing at a linear edge thereof in the direction of the flow of fluidic materials through the housing, one end of each of said mixing element in the radial direction of the housing being fixedly disposed in the inner wall of the housing and extending across and through the longitudinal axis of said cylindrical housing, said mixing element further having a space formed between another end of each said mixing element and the adjacent inner wall thereof so that the materials trapped by said element are permitted to pass therethrough.
Claim 3
Dependent Claim
38 words
A motionless mixing device as claimed in claim 1, wherein an outer coating tube is mounted on the outer wall of the housing in order to provide a liquid tight connection between the housing and the mixing elements.
Claim 4
Dependent Claim
21 words
A motionless mixing device according to claim 2 wherein said mixing elements are positioned within said housing in a helical pattern.
Claim 5
Dependent Claim
153 words
A motionless mixing device, comprising a hollow cylindrical housing for introducing a plurality of fluidic materials and a plurality of substantially triangular in configuration mixing elements fixedly positioned within the housing, each of the mixing elements being inclined transversely of the longitudinal axis of the housing in the directional flow of the fluidic materials through the housing, each mixing element having an inclined linear edge which is inclined in the direction of the flow of fluidic materials through the housing, one end of each of said mixing elements in the radial direction of the housing being fixedly disposed in the inner wall of the housing and extending across and through the longitudinal axis of said cylindrical housing, said mixing element further having a space provided between the other end of each of said mixing elements and the adjacent inner wall thereof so the materials trapped by said element are permitted to pass therethrough.
Claim 6
Dependent Claim
153 words
A motionless mixing device, comprising a hollow cylindrical housing for introducing a plurality of fluidic materials and a plurality of substantially triangular in configuration mixing elements fixedly positioned within the housing, each of the mixing elements being inclined transversely of the longitudinal axis of the housing in the directional flow of the fluidic materials through the housing, each mixing element having an inclined linear edge which is inclined in the direction of the flow of fluidic materials through the housing, one end of each of said mixing elements in the radial direction of the housing being fixedly disposed in the inner wall of the housing and extending across and through the longitudinal axis of said cylindrical housing, said mixing element further having a space provided between the other end of each of said mixing elements and the adjacent inner wall thereof so the materials trapped by said element are permitted to pass therethrough.
Claim 7
Dependent Claim
37 words
A motionless mixing device as in claim 4 wherein an outer coating tube is mounted on the outer wall of the housing in order to provide a liquid tight connection between the housing and the mixing elements.
Claim 8
Dependent Claim
21 words
A motionless mixing device according to claim 5 wherein said mixing elements are positioned within said housing in a helical pattern.
