of the disclosure: A novel delayed-release form for pharmaceutical active compounds, characterized by a core containing the active compound and a diffusioninhibiting, adhesive coating layer having a thickness in the range from 0.01 to 10 .mu.m, consisting of a chemical network which has been applied to the support in a plasma-assisted chemical deposition process, and a process for its production a...

Summary Process and Installation for the Identification of Materials This invention consists of a process and an installation to identify materials. Materials are exposed to laser energy, and after the material is heated, the thermal radiation of the material is measured. Following this, a material-specific evaluation takes place, based on optical and thermal material properties. At least one area...

Exhaust noise emitted by a pneumatically operated tool, such as a nailer, is damped by an external damping ring which surrounds the exhaust openings. Preferably, the damping ring is inserted into an outwardly open circumferential groove into which the exhaust openings of the tool housing merge. The ring is sufficiently elastic to permit the escape of the exhaust air, thereby damping the noise. The...
