Abstract: A safety device adapted to an electrochemical cell, the cell having a container in which a coil is placed, the container including at least one first wall provided with at least one rupture initiator, designed to break in the event of a fault so as to expel the gases, and a second wall arranged to ensure the coil is held in said container, the safety device has a holding device arranged to ensure an abutment against said second wall of the cell so as to hold it in position in the event of thermal runaway and to retain the coil on the inside of the container, a gas releasing device, arranged to ensure the expulsion of the gases from the cell, in the event of thermal runaway.

Abstract: A device to visualize in-line the polymer melting in plasticating screw machines has an external metallic cylinder to be fixed in radial position regarding the barrel of the plasticating machine, a bushing with an optical window clear to the visible light spectrum resistant to pressure and temperature positioned in such a way that its external face is tangent to the internal surface of the barrel of the plasticating machine, and an internal metallic cylinder to guide the coolant gas and allow the use of an observation probe with operating temperature limits and an illumination system.

Abstract: An image of high-aspect-ratio objects is analyzed to locate linear features within the image. The gradient direction for each pixel is determined, and connected pixels having similar gradient directions are grouped into line support regions. A linear feature is determined for each line support region. The linear features are analyzed to identify those that are co-linear. The linear features are then analyzed to find groups that are parallel and that sufficiently overlap. Additional sets of linear features that intersect the identified group are combined into that group. The line support regions of the grouped linear features are analyzed to determine representative orientation and/or dimensional information, which is analyzed to determine statistical information about a plurality of the objects. This information is used to monitor or control one or more processes associated with the objects, to reject the objects or a structure or device comprising the objects, or the like.
