There are provided processes for preparing a metal hydroxide comprising (i) at least one metal chosen from nickel and cobalt and optionally (ii) at least one metal chosen from manganese, lithium and aluminum, the process comprising: reacting a metal sulfate comprising (i) at least one metal chosen from nickel and cobalt and optionally (ii) at least one metal chosen from manganese, lithium and aluminum with lithium hydroxide, sodium hydroxide and/or potassium hydroxide and optionally a chelating agent in order to obtain a solid comprising the metal hydroxide and a liquid comprising lithium sulfate, sodium sulfate and/or potassium sulfate; separating the liquid and the solid from one another to obtain the metal hydroxide; submitting the liquid comprising lithium sulfate, sodium sulfate and/or potassium sulfate to an electromembrane process for converting the lithium sulfate, sodium sulfate and/or potassium sulfate into lithium hydroxide, sodium hydroxide and/or potassium hydroxide respectively; reusing the sodium hydroxide obtained by the electromembrane process for reacting with the metal sulfate; and reusing the lithium hydroxide obtained by the electromembrane process for reacting with the metal sulfate and/or with the metal hydroxide.

A foldable ramp for evacuation of a vehicle, the ramp including hingedly connected primary and secondary side members, a primary fixed panel fixedly attached the primary side members, a primary flipping panel extending between the primary side members adjacent the primary fixed panel and having a first end pivotally connected to the primary side members and a second end free from the side members, and a secondary flipping panel extending between the secondary side members and having a first end free from the side members and hingedly connected to the second end of the primary flipping panel and a second end pivotally connected to the secondary side members. The ramp is configurable between a folded and a deployed position, with the panels in the deployed position forming a ramp surface and the panels in the folded position being stacked one against the other.
