FLEXIBLE FOLDING BATTERY COVER

Battery covers and methods for producing battery covers are described. One battery cover described herein includes a single sheet of material formed into a substantially rectangular box shape with an opening formed along one side, the rectangular box shape capable of being folded into a flattened shape for transportation and the material including a flexible laminate of at least one layer of synthetic fiber and a polymer film layer. The material has a thickness and other properties such that when the battery cover is unfolded, the material substantially maintains the rectangular box shape, and when the battery cover is folded into the flattened shape, the material maintains a spring force such that, unless restrained, the battery cover would unfold to the rectangular box shape.

Foldable battery cover of flexible

The utility model relates to a foldable battery cover of flexible. The battery cover that this paper described is including forming to being formed with the open -ended homogenous material thin slice of rectangle box shape in fact along one side, rectangle box shape can fold into flat shape with be used for the transportation and the material includes the flexible laminating thing on an at least one deck synthetic fiber and a polymer thin film layer. The thickness of material makes with other characteristics works as when the battery cover expandes, the material keeps in fact rectangle box shape is and work as the battery cover is folded during flat shape, only if keeping elasticity, the material retrains, otherwise the battery cover will expand rectangle box shape.

Verfahren und Vorrichtung zur Probeentnahme und zur rechnergestützten Analyse des Anteils unverbrannter Bestandteile von feinkörnigen Verbrennungsrückständen

Sampling method for computer analysis of unburnt carbon in fine ash

A sample is taken from a conveyor system (2) filled with ash. The sample is placed in a feed container (1). The sample is de-aerated before it enters an analyzer (7), and before the start of analysis, it is compacted and heated to a predetermined temperature. The sample is analyzed using microwave resonance. The ash sample is fed back out of the analyzer either to the conveyor system or collected as a reference sample. An Independent claim is also provided for a device for carrying out the method.
