Barium titanate-based compositions having a high tetragonality and methods of forming the same are provided, as well as devices formed from the compositions. The barium titanate-based compositions advantageously have a high tetragonality and small particle sizes. For example, in some embodiments, the barium titanate-based compositions have a tetragonality of greater than about 2.0 and an average particle size of less than about 0.3 micron. Some methods involve achieving high tetragonality by limiting the concentration of certain metals (other than barium or titanium) in the compositions and / or heat treating the compositions at relatively high temperatures. In some methods, the A / B ratio of the composition may be adjusted prior to heat treatment to ensure that a small particle size is maintained during heat treatment. The barium titanate-based compositions may be processed to form dielectric layers in electronic devices, such as MLCCs, having excellent electrical properties as a result of the high tetragonality and relatively small particle sizes.

An aseptic packaging installation in individual containers, comprising a stand on which there is mounted an enclosure (3) that has a floor (4) with an overhead ceiling (6) and that receives at least one rotatable platform (7) in a packaging zone (Z1) subjected to a sterile laminar stream flowing vertically from the ceiling of the packaging zone at a rate that is adapted to establish in the packaging zone a first pressure (P1) that is greater than the surrounding pressure, the installation being characterized in that the enclosure is provided with laminar stream exhaust means for removing the laminar stream from the packaging zone via a buffer zone extending between the packaging zone and the floor.

A system for measurement and analysis of pipeline contaminants is provided. The system includes a first assembly for engaging a pipeline from which a first fluid flow sample may be isokinetically collected for measurement of aerosol contaminants. The system also includes a second assembly for engaging the pipeline from which a second fluid flow sample may be collected for chromatographic analysis of the aerosol contaminants. The system may further include a third assembly for engaging the pipeline from which a fluid flow sample may be obtained for measurement of solid contaminants. Information on aerosol contaminants and solid contaminants can subsequently be used to select an appropriate extraction technology to control the presence of aerosol and solid contaminants within the pipeline. Information from the chromatographic analysis, on the other hand, may be used to identify the origin of the aerosol contaminants, so that corrective measures can be implemented to minimize the presence of aerosol contaminants within the pipeline. A method for measurement and analysis of pipeline contaminants is also provided.

A mold for vulcanizing a tire tread comprising a molding surface able to mold a tread surface of the tread of the tire and at least one bar of length L and of width W able to mold a groove in the tread. The bar comprises two lateral faces extending along the length of the bar and projecting from the molding surface and an upper face connecting the said lateral faces. The mold comprises in the bar at least two cavities respectively opening onto the two lateral faces of the bar without opening onto the upper face of this bar. These cavities overlap in the width of the bar. The mold further comprises a first element added into the bar beforehand, this first element separating the two cavities in the length of the bar.
