"ELECTROLYTE POUR ACCUMULATEURS AU PLOMB".
Dans le brevet No 345849 il est dit qu'il est nécessaire de rajouter de temps à autre à l'électrolyte la quantité d'aoide phosphorique perdue pendant le fonctionnement. Il n'est pas com- mode de compléter ainsi l'éleotrolyte en versant une solution aqueuse d'acide phosphorique dans l'élément à cause de la mesure de la quantité de liquide versée ; c'est pou quoi beauooup d'usa-
<Desc/Clms Page number 2>
gers deséléments ont omis de le faire. Suivant l'invention on évite cette incommodité en prenant de l'acide phosphorique à l'é- tat solide, sous forme de moroeaux réguliers de poids déterminé et peu ou pas hygrosoopiques, et en l'introduisant dans l'élément, dans l'électrolyte duquel il est dissous.
En comptant simplement ces morceaux on peut déterminer ainsi commodément la quantité d'acide phosphorique fixée par le brevet No 345849. Les morceaux peuvent avoir par exemple la forme de tiges, tablettes, boules ou cubes. Ils sont constitués de préférence par l'acide métaphos- phorique solide ou par des phosphates de métaux ne nuisant pas à l'accumulateur, tels que le calcium, le barium, le magnésium, l'aluminium, le zino, le cadmium, le plomb.
Toutefois il n'est nullement nécessaire d'ajouter à l'acide orthophosphorique, pour le rendre solide, les quantités de ces oxydes nécessaires pour former les sels neutres ; au contraire, ainsi que l'ont montré des essais, des quantités sensiblement plus petites de ces oxydes métalliques sont suffisantes, de sorte que les morceaux sont ain- si constitués par le mélange d'un sel .acide de l'acide orthophos phorique ou d'un tel sel avec de l'acide libre. On peut par exem- ple délayer 700 gr. d'acide orthophosphorique d'un poids spéoifi- que de 1,75 avec 150 à 200 gr. d'oxyde de zino en chauffant dou- oement et oomprimer en tablettes après le refroidissement. Ces morceaux peuvent servir non seulement à compléter la teneur en acide phosphorique de la façon décrite, mais aussi à préparer l'éleotrolyte frais contenant de l'acide phosphorique.
Dans ce cas on les met par exemple dès le début au fond de petits éléments transportables destinés à être remplis, en dehors de l'usine, d'acide sulfurique pur et étendu.

"ELECTROLYTE FOR LEAD ACCUMULATORS".
In patent No. 345849 it is stated that it is necessary to add from time to time to the electrolyte the quantity of phosphoric acid lost during operation. It is not convenient to thus supplement the electrolyte by pouring an aqueous solution of phosphoric acid into the element because of the measure of the quantity of liquid poured; what a lot of us-
<Desc / Clms Page number 2>
most elements failed to do so. According to the invention, this inconvenience is avoided by taking phosphoric acid in the solid state, in the form of regular pieces of determined weight and little or no hygrosoopic, and by introducing it into the element, into the electrolyte from which it is dissolved.
By simply counting these pieces one can thus conveniently determine the amount of phosphoric acid set by Patent No. 345849. The pieces may have, for example, the shape of rods, tablets, balls or cubes. They are preferably formed by solid metaphosporic acid or by metal phosphates which do not harm the accumulator, such as calcium, barium, magnesium, aluminum, zino, cadmium, lead. .
However, it is not at all necessary to add to the orthophosphoric acid, to make it solid, the quantities of these oxides necessary to form the neutral salts; on the contrary, as tests have shown, substantially smaller quantities of these metal oxides are sufficient, so that the pieces are thus formed by the mixture of an acid salt of orthophos phoric acid or of such a salt with free acid. For example, 700 g can be diluted. orthophosphoric acid with a specific weight of 1.75 with 150 to 200 gr. of zino oxide by gently heating and compress into tablets after cooling. These pieces can be used not only to supplement the phosphoric acid content as described, but also to prepare the fresh electrolyte containing phosphoric acid.
In this case, for example, they are placed from the start at the bottom of small transportable elements intended to be filled, outside the factory, with pure and extensive sulfuric acid.
