Claim 2

Independent Claim 12 words

A METHOD OF PREPARING AN ANIMAL FOOD PRODUCT COMPRISIN THE STEPS OF:

Claim 3

Dependent Claim 30 words

PLACING A MASS ANIMAL FLESH AND BONE MATERIAL WITHIN A CHAMBER BETWEEN A PLUNGER, AXIALLY MOVABLE WITHIN SAID CHAMBER AND PERFORATED EXTRACTOR MEANS ADJACENT AN OUTLET END OF SAID CHAMBER,

Claim 4

Dependent Claim 30 words

PLACING A MASS ANIMAL FLESH AND BONE MATERIAL WITHIN A CHAMBER BETWEEN A PLUNGER, AXIALLY MOVABLE WITHIN SAID CHAMBER AND PERFORATED EXTRACTOR MEANS ADJACENT AN OUTLET END OF SAID CHAMBER,

Claim 5

Dependent Claim 54 words

ADVANCING SAID PLUNGER AGAINST THE MASS UNDER A PRESSURE OF NOT LESS THAN 120,000 PSI TO FORCE THE FLESH AND BONES OF THE MASS THROUGH SAID PERFORATED EXTRACTOR MEANS TO REDUCE THE BONES TO A SIZE AND CONSISTENCY INDISTINGUISHABLE FROM THE REMAINDER OF THE RESULTANT FOOD PRODUCT WHICH EMERGES FROM SAID EXTRACTOR PLATES; AND

Claim 6

Dependent Claim 54 words

ADVANCING SAID PLUNGER AGAINST THE MASS UNDER A PRESSURE OF NOT LESS THAN 120,000 PSI TO FORCE THE FLESH AND BONES OF THE MASS THROUGH SAID PERFORATED EXTRACTOR MEANS TO REDUCE THE BONES TO A SIZE AND CONSISTENCY INDISTINGUISHABLE FROM THE REMAINDER OF THE RESULTANT FOOD PRODUCT WHICH EMERGES FROM SAID EXTRACTOR PLATES; AND

Claim 7

Dependent Claim 54 words

advancing said plunger against the mass under a pressure of not less than 120,000 psi to force the flesh and bones of the mass through said perforated extractor means to reduce the bones to a size and consistency indistinguishable from the remainder of the resultant food product which emerges from said extractor plates; and

Claim 8

Dependent Claim 54 words

advancing said plunger against the mass under a pressure of not less than 120,000 psi to force the flesh and bones of the mass through said perforated extractor means to reduce the bones to a size and consistency indistinguishable from the remainder of the resultant food product which emerges from said extractor plates; and

Claim 9

Dependent Claim 29 words

A method of preparing an animal food product according to claim 1 further comprising the step of straining the resultant food product after it emerges from said extractor means.

Claim 10

Dependent Claim 54 words

advancing said press means against the animal to extrude flesh and bones thereof through said said tortuous path under sufficient pressure to effect a disintegration of the flesh and bones into a homogeneous product, the bones being reduced to an indistinguishable gelatinous substance which forms a binder to maintain said product in desired shapes.

Claim 11

Dependent Claim 54 words

advancing said press means against the animal to extrude flesh and bones thereof through said said tortuous path under sufficient pressure to effect a disintegration of the flesh and bones into a homogeneous product, the bones being reduced to an indistinguishable gelatinous substance which forms a binder to maintain said product in desired shapes.

Claim 12

Dependent Claim 33 words

The method of preparing an animal food product according to claim 1 further comprising the step of precutting the mass prior to introduction into said chamber to assure uniform filling of said chamber.

Claim 13

Dependent Claim 12 words

collecting the resultant food product from said outlet end of said chamber.

Claim 14

Dependent Claim 12 words

collecting the resultant food product from said outlet end of said chamber.

Claim 15

Dependent Claim 12 words

COLLECTING THE RESULTANT FOOD PRODUCT FROM SAID OUTLET END OF SAID CHAMBER.

Claim 16

Dependent Claim 12 words

COLLECTING THE RESULTANT FOOD PRODUCT FROM SAID OUTLET END OF SAID CHAMBER.

Claim 17

Independent Claim 12 words

A method of preparing an animal food product comprising the steps of:

Claim 18

Independent Claim 12 words

A method of preparing an animal food product comprising the steps of:

Claim 19

Independent Claim 91 words

A method of preparing a fish product comprising the steps of introducing a mass of fish flesh and bone material into a chamber; forcing the mass under pressure through a a series of perforations which define a tortuous path, said perforations defining an area significantly smaller than the area of said chamber to extrude the flesh and bone material into a homogeneous produCt, said pressure being of sufficient magnitude to transform substantially all of the bone material into a gelatinous substance within the product, and removing the product from said chamber.

Claim 20

Independent Claim 91 words

A method of preparing a fish product comprising the steps of introducing a mass of fish flesh and bone material into a chamber; forcing the mass under pressure through a a series of perforations which define a tortuous path, said perforations defining an area significantly smaller than the area of said chamber to extrude the flesh and bone material into a homogeneous produCt, said pressure being of sufficient magnitude to transform substantially all of the bone material into a gelatinous substance within the product, and removing the product from said chamber.

Claim 21

Independent Claim 105 words

An apparatus for preparing an animal food product comprising a chamber, a plunger axially movable within said chamber from an inlet end and toward an outlet end of said chamber, extractor means comprising stationary, stacked discs located axially within said chamber within the path of said plunger, said discs having perforations therein of determinant size and being arranged with respect to one another to define a tortuous path through said perforations and means for moving said plunger under a pressure of not less than 120,000 psi toward said outlet end, whereby animal flesh and bone material introduced into said chamber forced through said tortuous path.

Claim 22

Independent Claim 105 words

An apparatus for preparing an animal food product comprising a chamber, a plunger axially movable within said chamber from an inlet end and toward an outlet end of said chamber, extractor means comprising stationary, stacked discs located axially within said chamber within the path of said plunger, said discs having perforations therein of determinant size and being arranged with respect to one another to define a tortuous path through said perforations and means for moving said plunger under a pressure of not less than 120,000 psi toward said outlet end, whereby animal flesh and bone material introduced into said chamber forced through said tortuous path.

Claim 23

Dependent Claim 33 words

An apparatus for preparing an animal food product according to claim 6 wherein said perforations in said discs are no larger than one-eighth inch in diameter on an outlet side of said discs.

Claim 24

Dependent Claim 24 words

An apparatus for preparing an animal food product according to claim 6 further comprising a chute for continuously feeding animal material toward said opening.

Claim 25

Dependent Claim 28 words

An apparatus for preparing an animal food product according to claim 8 further comprising cutting means adjacent said chute for cutting the animals prior to entering said chamber.

Claim 26

Dependent Claim 19 words

An apparatus for preparing an animal food product according to claim 6 further comprising straining means adjacent said outlet.
