Abstract: A method for the manufacture of an adhesive from animal blood is described in which the blood is dried and stored as a dried mass of blood and in which this dried mass of blood is then converted to a sprayable solution of up to 40% concentration by the addition of water. The ready-to-use adhesive is finally prepared by the admixture, preferably during spraying, of a monobasic organic acid in a quantity sufficient to produce a pH value of the adhesive between 3.0 and 4.0.In a modification of the method an extender or diluent preferably in the form of sodium chloride, is added to the blood prior to drying. The drying step can be carried out by means of vacuum drying, freeze drying or drying through atomization. It is also advantageous to cool the blood to a temperature of approximately 4.degree. C. in the period between accumulation and drying.The resulting adhesive is particularly suitable for use as a binder in the manufacture of particle board from wooden chips.

Abstract: A paving mixture containing black asphalt which is changed to a color other than black by the addition of a limited amount of a coloring agent to the mixture, such as ferric oxide, to impart a permanent, distinctive color to the pavement without sacrificing any of the wearing qualities thereof. At the same time, the cost of the pavement is maintained within practical economic limits so that it may be used in the production of paved areas of limited extent, such as tennis courts, playgrounds, running tracks, parking lots, airport runways, etc. When the mixture is laid down in depths of one-fourth inch to twelve inches, the increased cost of the pavement is made up in a reasonably short period of time by the elimination of the need for painting the conventional black surface repeatedly, especially when the latter is subjected to extensive use and wear.

Abstract: The addition of aqueous dilutions of a sulfonic acid source of 0.2% to 0.8% acid concentration to an aggregate or to a composition of asphalt and aggregate in hot asphalt plants enables a decrease in the amount of asphalt required in comparison to compositions not so treated while achieving comparable strengths and durability when the composition is laid down as road paving material. The improved distribution of asphalt reduces usage by 10% to 40% and permits the incorporation of additional finely divided material to achieve higher strengths, or, inversely, to permit a higher percentage of voids to exist in the completed materials so as to provide for a porous paving material with suitable strength. The use of water in quantities of from 1,000 gallons to 3,000 gallons per 100 tons of aggregate and a sulfonic acid source in quantities of from 0.5 to 8 gallons per 100 tons of aggregate to provide an aggregate-acid-water composition having an initial pH of less than 3.

Abstract: Mixing (a) a carboxylic acid, (b) a divalent or trivalent metal oxide or hydroxide and (c) a foundry molding sand in the presence of an aqueous solution of (d) a carboxyl-group-containing polymer or (e) water followed by shaping and curing can provide sand molds having sufficiently high green strength without contamination of the working environment. The molding sand composition has excellent processability, which means filling of shapes or molds with the sand can be done with ease. The sand molds manufactured in this way can be disintegrated by a simple procedure. Therefore the molding sand can be used over and over again and does not cause environmental pollution due to disposal of the molding sand.

Abstract: In order to obtain a more uniform sheet-like glass fiber product, it has been discovered that the use of a treating formulation having phosphate esters of polyoxyalkylene alkyl alcohol, polyamine compound, organic acid with glass fibers gives a more uniform aqueous dispersion of glass fibers. The treating formulation can be added to the aqueous solution to which the glass fibers are to be dispersed and then the more uniform aqueous dispersion of glass fibers is conveyed to a separator to produce the more uniform sheet-like glass fiber product from the aqueous dispersion and the aqueous dispersion is recycled to disperse fresh glass fibers. Also, the treating formulation can be present by itself on glass fibers that are in a wet condition. In addition, the treating formulation can be present on glass fibers that are in a dry condition when the treating formulation is applied to the glass fibers from a sizing composition containing the treating formulation and a film-former.

The polymeric composition alone, or in admixture with a diluting agent which is a non-solvating agent for the hydroxyethyl cellulose, can be added to aqueous mediums, particularly heavy brines, to produce well servicing fluids.
