Abstract: Automated system for handling, in particular for overturning, containers such as cage trays for housing laboratory animals. The automated system being suitable to be positioned at the outlet module of a station for treating or washing, said containers and possibly other component parts of said cages such as the lid, the trough and similar component parts. The system then receives said containers and/or other component parts at the outlet from said treatment station, in particular washing station. The system can comprise a first conveyor belt capable of interfacing said outlet module so as to receive said containers and/or said component parts at the outlet of said treatment station. A second conveyor belt can be arranged in succession so as to define a transport direction of said containers and/or component parts substantially parallel to the feed direction of said containers and/or component parts at the exit from said treatment station.

Abstract: A washing machine, which is adapted for cages and accessories used in the field of research on laboratory animals, and which has a wash chamber and an assembly for introducing washing liquid and rinsing liquid into the wash chamber, includes: two loading levels in the wash chamber, each loading level having two shelves arranged in symmetrical positions relative to the median longitudinal axis of the wash chamber; supports for the shelves, the supports being located in symmetrical positions on both sidewalls of the wash chamber and allowing the shelves to be arranged at different tilting angles; three washing and rinsing assemblies oscillating and rotating about a respective longitudinal axis in the wash chamber, the three assemblies being fed by the assembly for introducing washing liquid and rinsing liquid, and being interposed between the loading levels and lying in a symmetrical vertical plane in the wash chamber; an assembly for causing the oscillation and rotation of the three washing and rinsing assembl

Abstract: A washing appliance for application in pharmaceutical production and/or preclinical pharmaceutical research centres, and for the execution of washing/rinsing steps on parts and components for pharmaceutical production, comprising a hydraulic circuit for the circulation of washing/rinsing liquid and a recirculation pump in the hydraulic circuit, comprising: a wash chamber adapted to contain said parts and components for pharmaceutical production to be washed, said chamber comprising one or two hermetically closed access doors; one or more washing systems, internal to the wash chamber and connected to said hydraulic circuit, and adapted to supply wash liquid into the chamber; an accumulation basin at the bottom of the wash chamber, for accumulating the washing/rinsing liquid, connected to said recirculation pump; a heat exchanger for heating or maintaining the temperature of the washing/rinsing liquid received through said recirculation pump and supplied to said one or more washing systems; a generator of ga

Abstract: A silicon wafer containing oxygen precipitate nucleation centers (or oxygen precipitates) and having a first face, a second face, and a central plane equidistant between the first and second faces. The nucleation centers (or oxygen precipitates) have a non-uniform distribution between the first and second faces with a maximum density of the nucleation centers (or oxygen precipitates) being in a region which is between the first face and the central plane and nearer to the first face than the central plane. The density of the nucleation centers (or oxygen precipitates) increases from the first face to the region of maximum density and decreasing from the region of maximum density to the central plane.

Abstract: A process for treatment of a silicon wafer to achieve therein a controlled distribution of the density of oxygen precipitate nucleation centers. In the process, one face of the wafer is shielded and the other, unshielded, face of the wafer is exposed to an atmosphere which contains nitrogen or a nitrogen compound gas and which has an essential absence of oxygen during a rapid thermal treatment at a temperature of at least about 1175.degree. C. The process generates nucleation centers which serve as sites for the growth of oxygen precipitates during a subsequent heat treatment and which have a peak density proximate the unshielded face of the wafer.
