Abstract: A deliming composition and a deliming method using graft polymers from polysaccharides and/or polypeptides or the corresponding derivatives, obtainable by radical polymerization of a monomer, selected at least from, or a monomer mixture of, acrylic acid or methacrylic acid or the mixtures thereof.

Abstract: The invention relates to specific chrome tanning agents and also to their use for the tanning of hides and skins, and to the leather and pelts obtainable as a result. It further provides a new process wherein the protein-masked chrome tanning agents of the invention are obtained from materials containing chromium and collagen, more particularly from leather production wastes such as leather shavings, for example. This enables recycling of chromium-containing leather production wastes, thereby permitting a significant reduction in the amount of such wastes, a fact which leads to considerable economic, environmental and logistical advantages.

Abstract: A method for charging a vehicle battery of a vehicle connected to a charging station involves determining by the vehicle of a first charge profile as a function of a maximum power rating of the charging station, a target state of charge, and a predefined charge period, and checking by the vehicle as to whether the target state of charge can be achieved within the predefined charge period.
