Abstract: In general this invention relates to an antifreeze composition that can be used in the cooling systems of internal combustion engines, for example, in heavy-duty diesel engines, light duty trucks and cars. The antifreeze composition can be added to water or other suitable liquid coolant in the cooling system, to lower the freezing point temperature of the coolant and inhibit corrosion of metallic components associated with the cooling system. The antifreeze composition is particularly well suited, although not exclusively, for use with hard water. The antifreeze composition includes an organic acid component comprising adipic acid and at least one of benzoic acid and one or more C9-C12 dicarboxylic acid—or salts of these acids. The antifreeze composition also includes other anti-corrosive additive, for example, molybdate, nitrite, nitrate silicate azoles and a variety of buffer agents.

Abstract: An aloe vera re-tanned leather for use in a glove, garment, sandal or shoe. The leather includes tanned leather having an internal fiber matrix. An aloe vera powder of aloe vera particles in a gel carrier is in the tanned leather in a retanning process so that the aloe vera particles in the gel carrier penetrate the internal fiber matrix and are temporarily trapped within the internal fiber matrix. The trapped aloe vera particles in the tanned leather gradually emerge from the inside surface of the leather to be in contact with, lubricate and treat the skin of a wearer of the glove, garment, sandals or shoes, whereby the aloe vera lubricated leather is particularly suitable for use in gloves, garments, sandals or shoes which come in contact with a wearer's skin. The process of retanning the leather to include the aloe vera in the leather and the gloves, garments, sandals and shoes incorporating the aloe vera retaining leather is also described.

Abstract: A dust-reducing composition for treating dry soil that includes a hygroscopic compound together with a hydrophobic compound in relative amounts sufficient to form a water-repellant surface on the soil. Also, a process for treating dry soil to reduce dust generation due to movement of traffic or air thereover. This process includes applying onto the soil a hygroscopic compound and subsequently applying a hydrophobic compound onto the hygroscopic compound containing soil. Alternatively, the process includes applying onto the soil an aqueous solution of a mixture of a hygroscopic compound and a hydrophobic compound. In either case, the hygroscopic and hydrophobic compounds are applied in relative amounts sufficient to form a water-repellant surface on the soil.

Abstract: The invention relates to a water-based biodegradable and non-toxic functional fluid for mechanical drives, preferably for use in steam engines. The object of providing such functional fluids for use in mechanical drives, particularly for the hydrodynamic lubrication of plain bearings, preferably for crankshafts of superheated steam engines, having customary bearing play which is not overly precise, is achieved. It should be capable of being used in closed power plant systems also at sump temperatures higher than 120° C., e.g. in the crankcase under a crank shaft, and should be water-based or water-dilutable. According to the invention, this is achieved by addition of a low percentage of polyaspartic acid to water or to water/glycol mixtures, preferably polyaspartic acid having a molar mass of from greater than 1,000 to 10,000 g/mol being used.
