  • Patent number: 4274830
    Abstract: A pharmaceutical tablet consists of a substrate containing a medicament and may be covered with a coating, said coating including a pigment comprising a natural water insoluble edible powder dyed with an edible natural dye. The pigment for coloring the tablet, or other pharmaceutical products, as well as food and cosmetics, is made by suspending a natural water insoluble edible powdered substrate in an aqueous vehicle and dyeing the suspended powdered substrate with an edible natural dye. The liquid is removed to obtain the dry pigment powder of the invention which then can be suspended in a suspending medium and used for coating products to be colored such as food, drug and cosmetic products.

  • Patent number: 4247592
    Abstract: Synthetic fibers such as polyethylene terephthalate and nylon are treated with certain polydiorganosiloxanes to provide improved properties such as "hand" and water repellency.

  • Patent number: 4242092
    Abstract: The color printing of textile webs or structures such as carpets and tiles which are tufted or non-woven wherein the color is sublimatic dyestuff carried by an air permeable printing foil and this is placed over the textile structure with the dyestuff facing the textile structure. Heat is applied to vaporize the dyestuff and a pressure differential across the textile structure causes an air flow through the sheet structure and printing foil to affect penetration of the dye vapor into the structure. The dyestuff deposits on the textile fibres and filaments in the pattern it appeared on the printing foil. The said pressure differential is preferably produced by creating a vacuum at the side of the sheet structure opposite the printing foil.
