Abstract: Battery tray (1) for vehicle (50) comprising a closed frame (10), a floor (4) and a roof (6), wherein the frame (10), the floor (4) and the roof (6) define a housing (8) adapted to receive batteries, and the frame (10) comprises a profile (10a) having a substantially constant cross section. The profile (10a) comprises an internal wall (12a) delimiting the housing (8) and an external wall (14a) opposite the internal wall (12a), the internal wall (12a) and the external wall (14a) being spaced apart from each other.

Abstract: In a method for making laminated glass, a sheet includes two glass substrates with an interlayer sheet between them. This sheet includes a polymer based film provided on one of the surfaces with a thin functional layer. The sheet is cut out in dimensions substantially identical to or greater than one of the glass substrates. The sheet is slit on at least the thickness of the film provided with the functional layer so as to delimit at least a peripheral zone of the film located between the slitting line and its edge. The interlayer sheet is assembled between the glass substrates. The peripheral zone is then detached by mechanical traction to transform the laminated glass sheet.

Abstract: Processes for the production of sulfamic acid by the reaction of urea, sulfuric anhydride, and sulfuric acid in (1) a two-stage process wherein the sulfuric anhydride used in the first stage at a temperature less than 50.degree. C. is dissolved in a halogenated fluorocarbon or a mixture of halogenated fluorocarbons having a boiling point of from 0.degree. to 50.degree. C. or (2) in a one-stage process at 60.degree. to 100.degree. C. with the sulfuric anhydride dissolved in a halogenated fluorocarbon or a mixture of halogenated fluorocarbons having a boiling point below 100.degree. C. at atmospheric pressure, the halogenated fluorocarbon serving to remove the heat generated by the exothermic formation of the sulfamic acid from the original reactants.
