Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
94 words
In apparatus, for mixing, homogenizing and emulsifying liquid and liquid/solid mixtures, of the type comprising a plurality of individual chambers series connected in the flow direction connected to one another via supply and discharge channels, the improvement comprising forming the individual chambers in the shape of a double frustum and providing connecting channels which enter and leave the individual chambers tangentially in such a way that in the flow direction adjacent individual chambers are alternately connected in the area of their largest cross section and then in the area of their smallest cross section.
Claim 2
Dependent Claim
94 words
In apparatus, for mixing, homogenizing and emulsifying liquid and liquid/solid mixtures, of the type comprising a plurality of individual chambers series connected in the flow direction connected to one another via supply and discharge channels, the improvement comprising forming the individual chambers in the shape of a double frustum and providing connecting channels which enter and leave the individual chambers tangentially in such a way that in the flow direction adjacent individual chambers are alternately connected in the area of their largest cross section and then in the area of their smallest cross section.
Claim 3
Dependent Claim
20 words
Apparatus according to claim 1, wherein the individual chambers comprise frustums arranged with their smallest cross sections towards one another.
Claim 4
Dependent Claim
21 words
Apparatus according to claim 1 wherein the connecting pipes of the chambers in the flow direction consecutively have smaller cross sections.
Claim 5
Dependent Claim
21 words
Apparatus according to claim 1, wherein the connecting pipes of the chambers in the flow direction consecutively have larger cross sections.
Claim 6
Dependent Claim
17 words
Apparatus according to claim 1, wherein the individual chambers comprise a plurality of superimposed and interconnected frustums.
Claim 7
Dependent Claim
77 words
Apparatus according to claim 5, wherein the series connected individual chambers are arranged approximately in a circular formation, wherein said housing consists of individual plates arranged between end plates whereby the frustum shaped halves of the chamber and connecting pipes are cut into the stacked individual plates, and wherein the housing is placed in a further housing whereby the space formed between the housings is provided with supply and discharge pipes for a cooling or heating medium.
Claim 8
Dependent Claim
18 words
Apparatus according to claim 1, wherein the series connected individual chambers are arranged approximately in a circular formation.
Claim 9
Dependent Claim
34 words
Apparatus according to claim 1, comprising a housing consisting of individual plates arranged between end plates whereby the frustum shaped halves of the chamber and connecting pipes are cut into the stacked individual plates.
Claim 10
Dependent Claim
34 words
Apparatus according to claim 8, wherein the housing is placed in a further housing whereby the space formed between the housings is provided with supply and discharge pipes for a cooling or heating medium.
Claim 11
Dependent Claim
97 words
In apparatus, for mixing, homogenizing and emulsifying liquid and liquid/solid mixtures, of the type comprising a plurality of individual chambers series connected in the flow direction connected to one another via supply and discharge channels, the improvement comprising forming the individual chambers in the shape of a double frustum and providing connecting channels which enter and leave the individual chambers tangentially in such a way that in the flow direction adjacent individual chambers are alternately connected by means of the area of their smallest cross section being in communication with the area of their largest cross section.
Claim 12
Dependent Claim
97 words
In apparatus, for mixing, homogenizing and emulsifying liquid and liquid/solid mixtures, of the type comprising a plurality of individual chambers series connected in the flow direction connected to one another via supply and discharge channels, the improvement comprising forming the individual chambers in the shape of a double frustum and providing connecting channels which enter and leave the individual chambers tangentially in such a way that in the flow direction adjacent individual chambers are alternately connected by means of the area of their smallest cross section being in communication with the area of their largest cross section.
Claim 13
Dependent Claim
97 words
In apparatus, for mixing, homogenizing and emulsifying liquid and liquid/solid mixtures, of the type comprising a plurality of individual chambers series connected in the flow direction connected to one another via supply and discharge channels, the improvement comprising forming the individual chambers in the shape of a double frustum and providing connecting channels which enter and leave the individual chambers tangentially in such a way that in the flow directiOn adjacent individual chambers are alternately connected by means of the area of their largest cross section being in communication with the area of their smallest cross section.
