The invention concerns a method of comminuting and crushing solids which may be partially metallic such as, for example, blocks of reinforced concrete. In contrast to the known electrohydraulic method, in which comminution is brought about by the effect of shock waves applied to the solids from the exterior, with the novel method the solid is exploded as a result of shock waves being produced ther...

Mutants of the human PAI-1 protein are described which are inhibitors of neutrophil elastase or are inhibitors of vitronectin (Vn)-dependent cell migration. These mutants preferably comprise one or two amino acid substitutions in the reactive center loop of PAI-1, particularly at positions 331 and 346 of the mature protein. These mutants are notable in being resistant to inactivation by elastase, ...

A process is disclosed for manufacturing lead electrodes for accumulators. Lead grid elements (2, 3) are produced, provided with an active mass (5) and coated on both sides with glass microfibres (6, 7). In order to automate the process to a large extent, the introduction of the active mass and the coating with glass microfibres, which immediately follows the introduction of the active mass, are a...

The valve consists of a strip -1- onto which two coplanar strips -3, 4- are welded separated by an opening -5-. Production of the valve takes a strip -11- onto which two strips -12, 13- are welded separated by a space -5-. The valve obtained -16- is welded onto a laminar -17-, which forms part of the inflatable, with a hole -19- which has to coincide with the valve opening -5-. Next the first shee...
