Abstract: In an apparatus for applying ink patterns on oriented strand boards, the boards are serially moved closely adjacent to and past ink jets, and ink is deposited on the boards. To deposit the ink accurately on the boards they are advanced by pinch and drive rollers which also ensure that the boards are flat as they move past the jets. Detectors are used to detect boards which cannot be flattened or are irregular in shape and in such a case the ink jets are moved to avoid impact by an irregular board. During printing, the panels and the ink jets are about 0.0625 inches to about 0.125 inches apart, and the panels are moved at a rate of about 150 ft/minute to 600 ft/minute.

Abstract: Calcium phosphate colorants are provided that comprise calcium phosphate particles, a dye, and aluminum hydroxide and which are resistant to dye migration and suitable for use in food, drugs and cosmetics. The calcium phosphate particles are coated with a dye and the dye is fixed to the particles by the aluminum hydroxide. Also provided is a method for making a calcium phosphate colorant in which aluminum hydroxide is mixed with a calcium phosphate slurry to deposit aluminum hydroxide onto the calcium phosphate particles contained within the slurry.

Abstract: Bleach compositions comprising a percarbonate bleach and an amino tricarboxylic acid exhibit a reduced tendency to deposit calcium carbonate insolubles on substrates being bleached. Laundry compositions comprising percarbonate bleach and methyl glycine diacetic acid are provided.

Abstract: A detergent composition containing an inexpensive detergent builder in the form of a selected crystalline calcium carbonate that has been coated with a hydrotrope is provided. The crystalline calcium carbonate can be calcite and the hydrotrope can be xylene sulfonate. The crystalline calcium carbonate of the present invention is extremely inexpensive because it performs well even when used at large median particle sizes (e.g. less than 10 m.sup.2 /g surface areas).

Abstract: A detergent composition containing an inexpensive detergent builder in the form of a selected crystalline calcium carbonate that has been coated with an encapsulating material such as a carbohydrate is provided. The crystalline calcium carbonate can be calcite and the encapsulating material can be sucrose. The crystalline calcium carbonate of the present invention is extremely inexpensive because it performs well even when used at large median particle sizes (e.g. less than 10 m.sup.2 /g surface areas).

Abstract: Disclosed is a process for making a detergent composition comprising the steps of:i) making a detergent based composition comprising a solid acid source;ii) coating the solid acid source with a detergent surfactant; andiii) further adding an alkaline source and agglomerating said alkaline source with said acid source;and wherein the alkaline source and the acid source are capable of reacting together to produce a gas. Detergent compositions thus prepared show improved dispersability. Methods of laundering fabrics using such detergent compositions are disclosed.

Abstract: Disclosed are detergent compositions with improved solubility having a bulk density of at least 600 g/l, comprising a branched surfactant and from about 1% to about 3% a particulate acid source which is citric acid and an alkaline source, wherein said acid source and alkaline source are capable of reacting together to produce a gas, and wherein about 80% or more of the acid source has a particle size in the range of from about 150 microns to about 710 microns, with at least 37% by weight of the acid source having a particle size of about 350 microns or less.

Abstract: This is provided a detergent composition in compacted solid form containing(a) an organo diphosphonate crystal growth inhibitor; and(b) an alkalinity system comprising alkaline salts selected from the group consisting of alkali and alkaline earth carbonates, bicarbonates, hydroxides and silicateswherein at least part of the alkalinity system comprises particulate alkaline salts coated with an organic binder and the weight ratio of organic binder to alkalinity system in the detergent composition is from 1:100 to 1:1. A making process is also provided.
