Regarding claim 21, Fuchs discloses substantially all of the elements of the present invention as stated above in the rejection of claim 20. However, Fuchs does not disclose at least one inflation tube comprises a high-volume flushing tube and a low-volume flushing tube as claimed. Varotti discloses a flush device for a flush tank wherein the at least one inflation tube comprises a high-volume flushing tube (¶ 0018) and a low-volume flushing tube (¶ 0023), and wherein when the high-volume flushing button or the low-volume flushing button is triggered, the first driving conversion module generates the air pressure and fills the air into the pneumatic drainage valve (4a) via the high-volume flushing tube or the low-volume flushing tube (¶ 0018-0023). It would have been obvious to one of ordinary skill in the art to have modified the flushing tube of Fuchs, to have a high-volume flushing tube and a low-volume flushing tube as claimed, as taught by Varotti, in order to provide a full and partial flush control assembly (¶ 0012) Regarding claim 27, Fuchs discloses substantially all of the elements of the present invention as stated above in the rejection of claim 26. However, Fuchs does not disclose at least one inflation tube comprises a high-volume flushing tube and a low-volume flushing tube as claimed. Varotti discloses a flush device for a flush tank wherein the at least one inflation tube comprises a high-volume flushing tube (¶ 0018) and a low-volume flushing tube (¶ 0023), and wherein the pneumatic drainage valve (4a) is configured to open for a longer opening time duration when the high-volume flushing tube is triggered than when the low-volume flushing tube is triggered (¶ 0018-0023). It would have been obvious to one of ordinary skill in the art to have modified the flushing tube of Fuchs, to have a high-volume flushing tube and a low-volume flushing tube as claimed, as taught by Varotti, in order to provide a full and partial flush control assembly (¶ 0012) Conclusion The prior art made of record in the PTO-892 form and not relied upon is considered pertinent to applicant's disclosure. Reynolds (US 1943041) is directed to the state of the art as disclosing a concealed flush tank including a flush tank (15), a plate (20), a handle (22), a supply pipe (24), and a water outlet (26).
