Abstract
Abstract A method and apparatus for mixing solid materials and liquids are provided. More specifically, such materials include particulate solids such as glass fibers and glass flakes, and foamable mixtures of two or more liquid components. The liquid components are first thoroughly mixed together before being mixed with the particulate solids. The mixed liquid is then supplied to a central zone and directed outwardly to the particulate solids in a zone surrounding the central one. After the solids and liquid are combined, this mixture is further mixed in a subsequent zone and then discharged to a location of use in a very short period of time, prior to the reaction and foaming of the liquid components.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
73 words
A method of mixing particulate solid material with liquid components which, when mixed together, form a foamable mixture, said method comprising mixing the foamable liquid components together, subsequently supplying the mixed liquid to a first, central zone, supplying the particulate solid material to a second zone surrounding the first zone, directing the mixed liquid outwardly from the first zone toward the second zone, and mixing together the solid material and the mixed liquid.
Claim 2
Independent Claim
73 words
A method of mixing particulate solid material with liquid components which, when mixed together, form a foamable mixture, said method comprising mixing the foamable liquid components together, subsequently supplying the mixed liquid to a first, central zone, supplying the particulate solid material to a second zone surrounding the first zone, directing the mixed liquid outwardly from the first zone toward the second zone, and mixing together the solid material and the mixed liquid.
Claim 3
Dependent Claim
31 words
A method according to claim 1 characterized by mixing together the particulate solid material and the mixed liquid at a location beyond the location where the mixed liquid is directed outwardly.
Claim 4
Dependent Claim
20 words
A method according to claim 1 characterized by rotating the liquid in the first zone prior to directing it outwardly.
Claim 5
Dependent Claim
24 words
A method according to claim 1 characterized by directing the mixed liquid outwardly from several locations at the first zone toward the second zone.
Claim 6
Independent Claim
79 words
A method of mixing solid particles with liquid which comprises two liquid components, said method comprising mixing together said liquid components, subsequently supplying the mixed liquid to a central zone, supplying the particles to a second, annular zone surrounding the first zone, directing the mixed liquid outwardly from the first zone to the solid particles in the second zone, moving the mixed liquid and solid particles along the second zone, and mixing together the particles and the mixed liquid.
Claim 7
Independent Claim
79 words
A method of mixing solid particles with liquid which comprises two liquid components, said method comprising mixing together said liquid components, subsequently supplying the mixed liquid to a central zone, supplying the particles to a second, annular zone surrounding the first zone, directing the mixed liquid outwardly from the first zone to the solid particles in the second zone, moving the mixed liquid and solid particles along the second zone, and mixing together the particles and the mixed liquid.
Claim 8
Dependent Claim
39 words
A method according to claim 5 characterized by said liquid components producing a foam a period of time after being mixed together, and mixing together the particles and mixed liquid prior to initiation of foaming by the liquid mixed.
Claim 9
Dependent Claim
35 words
A method according to claim 5 characterized by directing the mixed liquid outwardly from the first zone to the solid particles in the second zone at a plurality of locations spaced along the first zone.
Claim 10
Dependent Claim
25 words
A method according to claim 7 characterized by rotating the mixed liquid in the first zone and directing the mixed liquid outwardly by centrifugal force.
Claim 11
Dependent Claim
119 words
Apparatus for mixing a foamable liquid comprising two liquid components with particulate solid material, said apparatus comprising a hollow shaft forming a central zone, means for rotating said hollow shaft, means for mixing together the liquid components and for supplying mixed liquid to said central zone, means forming an annular zone around the central zone, means for supplying the particulate solid material to said annular zone, means associated with the hollow shaft for directing mixed liquid in said central zone outwardly toward said annular zone, and auger means mounted on said shaft in said annular zone for moving the mixed liquid and the particulate solid material along the annular zone after they are brought together at the annular zone.
Claim 12
Dependent Claim
119 words
Apparatus for mixing a foamable liquid comprising two liquid components with particulate solid material, said apparatus comprising a hollow shaft forming a central zone, means for rotating said hollow shaft, means for mixing together the liquid components and for supplying mixed liquid to said central zone, means forming an annular zone around the central zone, means for supplying the particulate solid material to said annular zone, means associated with the hollow shaft for directing mixed liquid in said central zone outwardly toward said annular zone, and auger means mounted on said shaft in said annular zone for moving the mixed liquid and the particulate solid material along the annular zone after they are brought together at the annular zone.
Claim 13
Dependent Claim
28 words
Apparatus according to claim 9 characterized further by additional means for mixing the mixed liquid and the particulate solid material after being brought together at the annular zone.
Claim 14
Dependent Claim
29 words
Apparatus according to claim 9 characterized by said central zone formed by said hollow shaft is elongate and extends through at least a substantial portion of said annular zone.
Claim 15
Dependent Claim
31 words
Apparatus according to claim 11 characterized by said directing means directs mixed liquid in said central zone toward said annular zone from a plurality of locations spaced along said hollow shaft.
