Abstract
Abstract The device comprises a plurality of superimposable elements, in each of which there are formed cavities and holes arranged to originate channels for conveying the components, the said channels being disposed so as to originate a plurality of channel assemblies disposed in series to each other, each assembly comprising a first central channel, second channels with axes are substantially orthogonal to the axis of the said first channel, which second channels communicate with this latter and are disposed radially with respect to it, third channels, each of which has its axis parallel to that of the said first channel and originates from a corresponding second channel, and fourth channels whose axes are substantially orthogonal to the axis of the said first channels and which are disposed radially with respect to it.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
195 words
A mixer device arranged to homogeneously mix two or more components in liquid or semiliquid state, particularly the components of a mixture comprising a solid phase and a liquid phase of a metal alloy, characterized in comprising a plurality of superimposable elements, in each of which there are formed cavities and holes arranged to give rise to channels for conveying the said components, the said channel being disposed in such a manner as to originate a plurality of channel assemblies disposed in series to each other, each assembly comprising a first central channel, second channels whose axes are substantially orthogonal to that of the said first channel and which communicate with the said first channel and are disposed radially relative to it, third channels each of which has its axis parallel to that of the said first channel and originates from a corresponding second channel, and fourth channels whose axes are substantially orthogonal to the axis of the said first channel and which are disposed radially with respect to it, each of the said fourth channels being in communication with one of the said third channels and with the first channel of an adjacent assembly.
Claim 2
Dependent Claim
195 words
A mixer device arranged to homogeneously mix two or more components in liquid or semiliquid state, particularly the components of a mixture comprising a solid phase and a liquid phase of a metal alloy, characterized in comprising a plurality of superimposable elements, in each of which there are formed cavities and holes arranged to give rise to channels for conveying the said components, the said channel being disposed in such a manner as to originate a plurality of channel assemblies disposed in series to each other, each assembly comprising a first central channel, second channels whose axes are substantially orthogonal to that of the said first channel and which communicate with the said first channel and are disposed radially relative to it, third channels each of which has its axis parallel to that of the said first channel and originates from a corresponding second channel, and fourth channels whose axes are substantially orthogonal to the axis of the said first channel and which are disposed radially with respect to it, each of the said fourth channels being in communication with one of the said third channels and with the first channel of an adjacent assembly.
Claim 3
Dependent Claim
54 words
A device as claimed in claim 1, characterized in that the said superimposable elements are of two different types, in elements of a first type there being formed the said second and third channels and in the elements of a second type there being formed the said fourth channels and the said first channel.
Claim 4
Dependent Claim
81 words
A device as claimed in claim 2, characterized in that each of the said superimposable elements is plate-shaped, the said first type elements comprising a plurality of cavities formed on a surface of the said plate in a substantially radial arrangement, and a plurality of holes arranged to traverse the said plate and each of which communicates with one of the said cavities, the said cavities and the said holes being arranged to generate the said second and third channels, respectively.
Claim 5
Dependent Claim
72 words
A device as claimed in claim 2, characterized in that the said elements of the second type comprise a plurality of cavites formed on a surface of the said plate in a substantially radial arrangement and a central hole arranged to traverse the said plate and communicating with the said cavity, the said cavities and the said hole being arranged to generate the said fourth channels and the said first channel, respectively.
Claim 6
Dependent Claim
53 words
A device as claimed in claim 4, characterized in that the said superimposable elements are cylindrical plate-shaped, on each of the said first type elements there being formed a cylindrical projection arranged to engage a corresponding cylindrical cavity of a second type element in order to center one element with respect to another.
Claim 7
Dependent Claim
30 words
A device as claimed in claim 1, characterized in that in at least one of the said superimposable elements there are formed conduits for the circulation of a cooling fluid.
