Abstract
Abstract A method of, and apparatus for, admixing at least two fluent material components, especially pulverulent or granular materials, wherein the internal compartment of a material receiving container is sub-divided by partition walls into two storage compartments having a volume ratio essentially corresponding to the desired mixing ratio of the material components. Each of the storage compartments is filled with the material components which are to be admixed. The filled material components are withdrawn from the storage compartments into a collecting zone in a ratio corresponding to the desired mixing ratio of such material components. Means serve to generate a negative pressure condition at the region of the collected material components withdrawn from said storage compartments, by means of which there is produced a material conveying fluid medium stream over the surface of the collected material components to remove therefrom the components of the collected material in a ratio corresponding to the desired mixing ratio. The thus withdrawn material components to are then transported by the conveying fluid medium stream to a consumer while admixing such material components with one another during movement to such consumer.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
180 words
A method of admixing at least two fluent material components, especially pulverulent or granular materials, comprising the steps of sub-dividing the internal compartment of a material receiving container into at least two storage compartments having a volume ratio essentially corresponding to the desired mixing ratio of the material components, filling into each one of the storage compartments one of the material components which are to be admixed, withdrawing from the storage compartments the therein filled material components in a ratio corresponding to the desired mixing ratio of such material components and depositing such withdrawn materials at a collecting zone, geneRating a negative pressure condition at the region of the collected material components withdrawn from said storage compartments, producing by means of such negative pressure condition a material conveying fluid medium stream over the surface of the collected material components to remove the components of the collected material in a ratio corresponding to the desired mixing ratio, and then transporting the thus withdrawn material components to a consumer while admixing such material components with one another during movement to such consumer.
Claim 2
Independent Claim
180 words
A method of admixing at least two fluent material components, especially pulverulent or granular materials, comprising the steps of sub-dividing the internal compartment of a material receiving container into at least two storage compartments having a volume ratio essentially corresponding to the desired mixing ratio of the material components, filling into each one of the storage compartments one of the material components which are to be admixed, withdrawing from the storage compartments the therein filled material components in a ratio corresponding to the desired mixing ratio of such material components and depositing such withdrawn materials at a collecting zone, geneRating a negative pressure condition at the region of the collected material components withdrawn from said storage compartments, producing by means of such negative pressure condition a material conveying fluid medium stream over the surface of the collected material components to remove the components of the collected material in a ratio corresponding to the desired mixing ratio, and then transporting the thus withdrawn material components to a consumer while admixing such material components with one another during movement to such consumer.
Claim 3
Independent Claim
180 words
A method of admixing at least two fluent material components, especially pulverulent or granular materials, comprising the steps of sub-dividing the internal compartment of a material receiving container into at least two storage compartments having a volume ratio essentially corresponding to the desired mixing ratio of the material components, filling into each one of the storage compartments one of the material components which are to be admixed, withdrawing from the storage compartments the therein filled material components in a ratio corresponding to the desired mixing ratio of such material components and depositing such withdrawn materials at a collecting zone, geneRating a negative pressure condition at the region of the collected material components withdrawn from said storage compartments, producing by means of such negative pressure condition a material conveying fluid medium stream over the surface of the collected material components to remove the components of the collected material in a ratio corresponding to the desired mixing ratio, and then transporting the thus withdrawn material components to a consumer while admixing such material components with one another during movement to such consumer.
Claim 4
Independent Claim
180 words
A method of admixing at least two fluent material components, especially pulverulent or granular materials, comprising the steps of sub-dividing the internal compartment of a material receiving container into at least two storage compartments having a volume ratio essentially corresponding to the desired mixing ratio of the material components, filling into each one of the storage compartments one of the material components which are to be admixed, withdrawing from the storage compartments the therein filled material components in a ratio corresponding to the desired mixing ratio of such material components and depositing such withdrawn materials at a collecting zone, geneRating a negative pressure condition at the region of the collected material components withdrawn from said storage compartments, producing by means of such negative pressure condition a material conveying fluid medium stream over the surface of the collected material components to remove the components of the collected material in a ratio corresponding to the desired mixing ratio, and then transporting the thus withdrawn material components to a consumer while admixing such material components with one another during movement to such consumer.
Claim 5
Dependent Claim
31 words
The method as defined in claim 1, including the step of withdrawing the material components from the storage compartments and depositing such at the collecting zone without any appreciable admixing thereof.
Claim 6
Dependent Claim
66 words
The method as defined in claim 2, wherein the material components withdrawn from the storage compartments are collected in the collecting zone in the form of an inverted pouring cone having the base thereof uppermost in such collecting zone, and moving the conveying fluid medium stream over the surface of the base of such inverted pouring cone to withdraw the components of the collected material therefrom.
Claim 7
Dependent Claim
23 words
The method as defined in claim 1, including the step of replenishing the supply of the material components removed from the storage compartments.
Claim 8
