Abstract: A disposable integral filter unit 10—suitable for the primary and/or secondary clarification of pharmaceutical fluids—is disclosed. The disposable integral filter unit has an inlet 40 and an outlet 60, and comprises a plurality of filter plates 20n interposed between a pair of end plates 24, 26. Each said filter plate 20n comprises a polymeric framework 28 with a deep gradient filter packet 35 embedded therein. The filter plates and end plates form in the aggregate a substantially fixed integral stack, wherein fluid entering the disposable integral filter unit 10 through said inlet 40 passes the deep gradient filter packet 35 of each filter plate 20n substantially contemporaneously (i.e., in “parallel”) prior to exiting said unit 10 through said outlet 60.

The disposable integral filter unit has an inlet 40 and an outlet 60, and comprises a plurality of filter plates 20n interposed between a pair of end plates 24, 26. Each said filter plate 20n comprises a thermoplastic framework 30 with a deep gradient filter packet 35 embedded therein. The filter plates and end plates form in the aggregate a substantially fixed integral stack, wherein fluid entering the disposable integral filter unit 10 through said inlet 40 passes the deep gradient filter packet 35 of each filter plate 20n substantially contemporaneously (i.e., in “parallel”) prior to exiting said unit 10 through said outlet 60.

Abstract: The invention is directed to an ink jet cartridge assembly, including a cartridge body and a print head. The cartridge body includes a die cavity and at least one groove disposed in communication with the die cavity and with an ambient environment. The print head is disposed at least partially within the die cavity. An adhesive is disposed within the die cavity between the body and the print head for bonding the print head to the body. The at least one groove defines a vent to the ambient atmosphere for a gas which may be produced during curing of the adhesive.
