A composition suitable for making acoustical tiles in a water-felting process comprises expanded perlite, cellulosic fiber, and, optionally, a secondary binder and mineral wool. The perlite has been treated to reduce its water retention.

A nail enamel based on a solvent mixture of nitrocellulose, and plasticizer(s) is made faster drying by incorporating a particular class of vinyl-silicone copolymers. Trapping of bubbles in the dried enamel is avoided by incorporating a dimethicone anti-foaming agent.

The invention discloses a coating solution for use in forming Bi-based ferroelectric thin films containing Bi, metallic element A (at least one selected from the group consisting of Bi. Pb, Ba, Sr, Ca, Na, K and rare earth elements) and metallic element B (at least one selected from the group consisting of Ti, Nb, Ta, W, Mo, Fe, Co and Cr), wherein it contains metal alkoxides of Bi, metallic element A and metallic element B respectively, and contains composite metal alkoxides formed by any two o...

The invention relates to a method for the recovery of xylose from xylose-containing aqueous solutions that contain over 30% by weight of xylose on dissolved dry solids. The solution is evaporated at low pressure to a solution supersaturated in respect of xylose, the solution is seeded, and the evaporation is continued at the boiling point of the solution until a crystal mass is obtained in which the xylose yield is 1 to 60%, and the xylose crystals are recovered.

The paint comprises in combination: pigments in a liquid solution chosen from the group of natural colouring earths; binders chosen from the group of milk, milk casein, egg white, egg yolk, starch paste and potato flour; compounds, mixed with said pigments and binders, chosen from the group of borax, kalinite, calcite, kaolin, slaked lime, mica and talc, sea salt and boron salts; and additives chosen from the group of vegetable oils, citrus-fruit juices, wine vinegar and natural waxes.

The present invention provides a process for the preparation of a noncentrifugal sugar composition. The process comprises the following steps: cane juice is filtered; a pH of the juice is adjusted to 5.0-6.0; sucrose or liquid sucrose or both is added to adjust a purity of the mixture to a range of 87.0 to 95.1% by weight; the mixture is heated and evaporated; and then the mixture is cooled to solidify with a strong shearing force being applied to obtain granules.

In order to obtain starch and proteins from the flour of legumes, in particular peas, the legume flour which has been treated with an aqueous decomposing agent, is fed into a first section (I) of a process line with several solids-liquids separation stages (6, 9, 10) for the purpose of extracting the proteins. The solid phase suspended in water from the final solids-liquids separation stage (10) of the first section (I) is then fed continually into a second section (II) of the process line with ...

A water-resistant and UV-resistant clear coat sealant and finish for protecting wood signs from weathering. The sealant is applied as a viscous liquid to the surface of the sign and allowed to stand until dry. It dries to a clear, durable protective coating with a satin luster.

The present invention relates to a size composition of improving the water repellency of paper in papermaking by virtue of adding prior to web formation to the pulp slurry such a sizing dispersion that contains at least a ketene dimer compound as a hydrophobic sizing agent, and further contains colloidal starch in an amount which is at least 150% by weight of the hydrophobic sizing agent. The invention is particularly applicable for improving the water repellency of paper containing calcium carb...

In a method of decalcification of purified sugar factory juices from a sugar factory process the juices, containing calcium ions, are sent onto an Na.sup.+ or K.sup.+ form strongly cationic ion exchange resin where the calcium ions are replaced with sodium and/or potassium ions. The ion exchange resin is then subject to regeneration (or washing) with dilute molasses. In a first variant of the method, the molasses is sent to the ion exchange resin in a cocurrent configuration. In a second variant...
