Abstract: An aqueous liquid composition containing dihydrogen phosphate salt, surfactant(s), and a dual coordinate bonding agent for iron cleans soiled metal surfaces without damaging any plastic parts that come into contact with the composition, supporting the growth of bacteria that cause unpleasant odors, or obscuring the transparency of any transparent window that it contacts. The composition is particularly useful for cleaning unpainted aluminum sided rail transport cars that have polycarbonate housings insulating electrical contact points that provide motive electric power to the cars; many conventional aqueous alkaline and acid cleaners promote stress cracking of polycarbonate plastics.

Abstract: Reactive hotmelt adhesives based on liquid polyether polyols and/or polyester polyols and aromatic diols with at least one diisocyanate have a very low melt viscosity and high early strength. They are particularly suitable for the bonding of substrates of poor thermal conductivity, such as foams and nonwoven materials, and heat-sensitive substrates.

Abstract: A reinforced beam assembly includes a channel-shaped beam which has an internal reinforcement member located within the channel. The reinforcement member is of generally W-shape and functions as a carrier for an expandable foam located between the inner surface of the reinforcement member and the inner surface of the beam. Upon expansion the foam is bonded to both surfaces.

Abstract: Hot-curing, foamable reactive compositions based on natural and/or synthetic rubbers containing olefinic double bonds, vulcanizing agents and blowing agents with a high percentage content of sulfur give foamed rubber compositions exhibiting high structural strength and high volume expansion. These compositions are suitable as multifunctional filling materials for hollow structures or hollow profiles in vehicle or machine construction. At one and the same time, they perform a sealing function, damp acoustic vibration and stiffen the hollow structures to a considerable extent.

Abstract: A process for removing dried paint residues from a difficultly accessible surface is provided. The surface is contacted with a slurry of particulate solids such as sodium hydrogen carbonate in a first liquid such as N-methyl pyrrolidone which is a solvent or swellant for the paint residues, followed by a different liquid such as isopropyl alcohol in which the first liquid is soluble (and which may also optionally contain particulate solids).

Abstract: An aqueous liquid chromate free primary composition for forming a protective coating on metals, particularly aluminum, is made by reacting cobalt(II) cations, carboxylate anions, at least one other type of coordinate complexing agent for cobalt(III) cations, and an oxidizing agent in an aqueous solution in which the molar ratio of carboxylate anions to cobalt(II) cations is from 0.10 to 6.8 and the aqueous solution contains no more than 1% of each of ammonia, ammonium ions, and nitrite ions. The primary layer formed by this or any other composition that forms a coating containing metal atoms and oxygen atoms on a metal substrate is advantageously sealed by further treatment with an aqueous solution of sodium ammonium decavanadate, optionally after an intermediate step of immersing in water for a few minutes between the primary treatment and the sealing treatment.

Abstract: A process for purifying a degraded oxime metal extractant organic phase from a metal extraction circuit wherein a degraded oxime metal extractant organic phase comprised of an oxime metal extractant, and aldehyde or ketone degradates in a water immiscible hydrocarbon solvent is reoximated thereby restoring the oxime extractant organic phase for further extraction in the metal extraction circuit. Optionally the degraded organic phase may be purified by distillation prior to reoximation. The distillation is carried out in a wiped film evaporator at temperatures above 180.degree. C. up to about 250.degree. C. at a pressure from about 0.5 mm Hg or lower up to about 10 mm Hg and the reoximation is carried out with hydroxylamine in the presence of a weak organic carboxylic acid as a phase transfer catalyst and in the presence of an alkali metal or alkaline earth metal hydroxide or carbonate, preferably sodium carbonate.

Abstract: The invention relates to a process for the production of higher dialkyl carbonates corresponding to formula (I):(R.sup.1 O)(R.sup.2 O)CO (I)which R.sup.1 and R.sup.2 may be the same or different and represent a linear or branched, saturated or unsaturated and/or alkoxylated alkyl group, by transesterification of lower dialkyl carbonates with higher alcohols in the presence of a catalyst. The process is characterized in that the transesterification is carried out in a column equipped with packings or internals through which the reactants flow in countercurrent to one another. Predominantly symmetrical dialkyl carbonates are obtained.

Abstract: The invention is an adhesive system for applying wrap around labels to containers. The system comprises a hotmelt pick-up adhesive which is active at the temperature which the label is applied and loses its bonding ability after the adhesive sets and an overlap adhesive for bonding the label overlap. At its application temperature, the pick-up adhesive has significantly higher adhesiveness, measured at its application temperature than at its conventional storage temperature. In addition, the adhesive preferably has a greater affinity for the label than for the container bearing the label. Consequently, the label can be easily removed from the hollow body without leaving residues of adhesive. If, nevertheless, a residual adhesive should remain on the hollow body, it can be dissolved by an alkaline solution.

Abstract: A packing container for liquid products comprises a closure which opens and closes automatically when the pressure in the container varies, such that the container is easy to handle irrespective of its filling level and can be reliably secured to a wall or the like. The container also includes at least one flat side wall for securing it to a flat surface, and at least one concave or convex actuation surface in the region of opposing side walls such that the user can apply manual pressure.

Abstract: A Process for Joining Plastic Moldings Plastic moldings can be joined with one-component or two-component adhesives, the connecting joint being spanned by metal strips. The metal strips are at least partly embedded in the adhesive layer. This process is particularly suitable for repairing damaged plastic moldings, more particularly automobile parts, for example fenders. The moldings repaired by the process according to the invention are restored to their original performance properties, more particularly dimensional rigidity, impact strength and appearance. In the event of scrapping, the moldings thus repaired are fully recyclable by conventional methods.
