Method of producing cellulosic pulp

Claim 1

THE METHOD OF PRODUCING FROM SUGAR CANE A SUBSTANTIALLY HOMOGENEOUS PULP CONSISTING PRINCIPALLY OF DIGESTED VASCULAR FIBRE COMPRISING SEPARATING FROM THE CRUSHED CANE SUBSTANTIALLY ITS ENTIRE CONTENT OF PARENCHYMATOUS TISSUE, WHILE LEAVING A RESIDUE COMPOSED OF A HETEROGENEOUS MIXTURE OF SUBSTANTIALLY THE ORIGINAL QUANTITIES OF FIBRO-VASCULAR BUNDLES AND SUBSTANTIALLY THE ORIGINAL QUANTITIES OF PERIPHERAL SCLERENCHYMA, FORMING THE SAID RESIDUE INTO A SUSPENSION IN LIQUID OF 5% TO 15% SOLIDS, DIGESTING THE SAID SUSPENSION UNDER PERDETERMINED ELEVATED TEMPERATURES WITH AN ALKALI COOK TO EFFECT PULPING OF SUBSTANTIALLY ALL THE FIBRES BELONGING TO THE FIBROVASCULAR BUNDLES WITHOUT SUBSTANTIAL DEGRADATION THEREOF, WHILE SOFTENING THE SCLERENCHYMA OF THE PERIPHERAL FIBRE BUNDLES, AND THEREAFTER REMOVING THE PERIPHERAL SCLERENCHYMA FROM THE PULPED VASCULAR CANAL FIBRES.

Claim 2

THE METHOD OF PRODUCING FROM SUGAR CANE A SUBSTANTIALLY HOMOGENEOUS PULP CONSISTING PRINCIPALLY OF DIGESTED VASCULAR FIBRE COMPRISING SEPARATING FROM THE CRUSHED CANE SUBSTANTIALLY ITS ENTIRE CONTENT OF PARENCHYMATOUS TISSUE, WHILE LEAVING A RESIDUE COMPOSED OF A HETEROGENEOUS MIXTURE OF SUBSTANTIALLY THE ORIGINAL QUANTITIES OF FIBRO-VASCULAR BUNDLES AND SUBSTANTIALLY THE ORIGINAL QUANTITIES OF PERIPHERAL SCLERENCHYMA, FORMING THE SAID RESIDUE INTO A SUSPENSION IN LIQUID OF 5% TO 15% SOLIDS, DIGESTING THE SAID SUSPENSION UNDER PERDETERMINED ELEVATED TEMPERATURES WITH AN ALKALI COOK TO EFFECT PULPING OF SUBSTANTIALLY ALL THE FIBRES BELONGING TO THE FIBROVASCULAR BUNDLES WITHOUT SUBSTANTIAL DEGRADATION THEREOF, WHILE SOFTENING THE SCLERENCHYMA OF THE PERIPHERAL FIBRE BUNDLES, AND THEREAFTER REMOVING THE PERIPHERAL SCLERENCHYMA FROM THE PULPED VASCULAR CANAL FIBRES.
