Patent number: 6348091Abstract: The present invention provides a process for continuous production of pigment flushes and an apparatus for carrying out the process. In the process of the invention, the pigment press cake is first fluidized. The fluidized press cake and a hydrophobic liquid organic medium are fed into a twin screw extruder. The kneading of the organic medium and press cake between the twin screws flushes the pigment into the organic medium. The water phase and flushed pigment phase are separated by removing at least part of the water phase through a vent in the extruder. An impediment to the flow of material downstream of the water vent causes the flush to accumulate in the vented section for a period of time sufficient to remove the desired amount of the water phase. The flush works over the impediment and passes downstream to where vacuum is applied to remove residual water from the flush. The flush may be further combined with other ink ingredients to form an ink product.Type: GrantFiled: September 17, 1999Date of Patent: February 19, 2002Assignee: Flint Ink CorporationInventors: Donald C.

Patent number: 6340387Abstract: A method for preparing high quality pigments having improved wettability, dispersibility and gloss characteristics, which method comprises grinding a pigment base material in a jet mill in the presence of an organic grinding aid, recovering ground pigment particles having a first organic layer, comprising the organic grinding aid, and treating the recovered pigment particles with an organic material, forming a second organic layer on the pigment particles, for improving the wettability, dispersibility and gloss characteristics of the treated pigment particles. Titanium dioxide, both untreated and pretreated with an inorganic coating, may be processed according to the method herein to yield high quality titanium dioxide pigment having improved wettability, dispersibility and gloss characteristics. The titanium dioxide pigment is particularly suitable for use in water-thinnable paint systems.Type: GrantFiled: February 29, 2000Date of Patent: January 22, 2002Inventors: Jürgen Orth-Gerber, Lothar Elfenthal, Siegfried Blümel

Publication number: 20010023653Abstract: A wall repair compound useful for filling and repairing cracks, holes, and other imperfections in a wall surface includes a conventional filler material, a conventional binder material, and a dust reducing additive which reduces the quantity of airborne dust particles generated when sanding the hardened joint compound. Airborne dust reducing additives include oils, surfactants, solvents, waxes, and other petroleum derivatives. The additive can be added to conventional ready-mixed joint compounds and to setting type joint compounds. A method of reducing the quantity of airborne dust generated when sanding a fully hardened joint compound includes mixing a sufficient quantity of the dust reducing additive with the joint compound prior to when the joint compound has been applied to the wall.Type: ApplicationFiled: March 29, 2001Publication date: September 27, 2001Applicant: 3M Innovative Properties CompanyInventor: Nathaniel P.
