US Patent:

48939439, Jan 16, 1990

Filed:

Jun 27, 1988

Appl. No.:

7/212268

Inventors:

John L. McKelvey - Lakeland FL

Assignee:

The Ink Company - West Sacramento CA

International Classification:

B01F 716

US Classification:

366312

Abstract:

Disclosed is an agitator apparatus for mixing tanked fluids while simultaneously wiping any adherent fluids from the tank wall. The device comprises a fluid agitating means rotationally mounted within the tank for mixing the fluid held therein. At least one tank wall wiper blade is attached to the fluid agitating means to skim or wipe fluid from the tank wall as rotational movement of the agitation means occurs. The agitation means may, in itself, comprise one or more perforated mixing panels attached to a rotating shaft member so as to effectively mix the fluid as the shaft member is rotated.

The Ink Company - Sacramento CA

International Classification:

C09D 1102

US Classification:

106 20

Abstract:

An improved method and system for reclaiming waste printing ink is disclosed. The inventive method is characterized by the initial heating and agitation of a quantity of undiluted waste ink. Such heating and agitation is carried out at a temperature and for a period of time sufficient to (a) volatilize water, and/or other liquids contained therein; and (b) reduce the viscosity of the waste ink to a viscosity which is suitable for subsequent processing. After the period of heating and agitation, the waste ink is centrifuged to separate paper lint and other fibrous particulate contaminants from the ink. The reclaimed clarified ink is then blended with virgin ink at a ratio which provides a press-ready reclaimed ink/virgin ink blend. The system of the present invention provides a system of vessels, lines, valves, pumps and attendant apparatus whereby the inventive method may be practiced.
