Abstract
Abstract Mixing process for at least two liquid or pastry products, characterized in that it consists in casting these products under pressure obliquely towards the same point on a surface so as to obtain a homogenous mixture which is then sent in the direction of a convergent-divergent nozzle which assures compression, followed by expansion of said mixture.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
150 words
A head for mixing multiple liquid products introduced thereinto under pressure, comprising: a body including therein a cavity having a central portion and having respective first and second concavely shaped end portions separated from each other along the axis of the cavity by said central portion, and said body further having a chamber located adjacent to said first end portion and communicating with said first end portion by a channel located on said axis and said second end portion having an opening therethrough. a cap removably closing said second end portion; injector means extending from outside the head into the central portion of the cavity, the injector means being supplied with said liquid products under pressure and having jet openings extending into the cavity and directed to project said products onto the concavely shaped second end portion; and a discharge tube extending from the chamber to discharge the mixed products.
Claim 2
Dependent Claim
150 words
A head for mixing multiple liquid products introduced thereinto under pressure, comprising: a body including therein a cavity having a central portion and having respective first and second concavely shaped end portions separated from each other along the axis of the cavity by said central portion, and said body further having a chamber located adjacent to said first end portion and communicating with said first end portion by a channel located on said axis and said second end portion having an opening therethrough. a cap removably closing said second end portion; injector means extending from outside the head into the central portion of the cavity, the injector means being supplied with said liquid products under pressure and having jet openings extending into the cavity and directed to project said products onto the concavely shaped second end portion; and a discharge tube extending from the chamber to discharge the mixed products.
Claim 3
Dependent Claim
27 words
A mixing head as set forth in claim 1, wherein said channel and said chamber are mutually proportioned to comprise a convergent-divergent nozzle for the discharged products.
Claim 4
Dependent Claim
55 words
A mixing head as set forth in claim 2, wherein said injector means comprises a separate injector for each of said multiple liquid products, said injectors extending into said cavity in spaced relationship around the central portion thereof, and said injectors having their jet openings directed obliquely toward the center of said second end portion.
Claim 5
Dependent Claim
41 words
A mixing head as set forth in claim 1, said removable cap having an inner end having an openable flushing valve therein, and the valve when closed having a surface following the contour of said second concave end of the cavity.
Claim 6
Dependent Claim
89 words
A mixing head as set forth in claim 4, said cap having a central bore therethrough extending in the direction of said axis, a ram in said bore selectively operable to reciprocate in the bore, and the ram being coupled to operate the valve to close it and thereby locate its surface to complete the contour of the second concave end of the cavity and to open it by moving the valve into the cavity, and means for passing flushing fluid through the valve when opened into the cavity.
Claim 7
Dependent Claim
41 words
A mixing head as set forth in claim 1, wherein said axis is substantially vertical and said second end portion is located above the first end portion and chamber, and said jet openings are directed upwardly toward said second end portion.
