Abstract: Un appareil compact a fonctionnement bidirectionnel de changement de traverses comprend un assemblage a poutres extensibles telescopiques (200) portees dans un berceau de support monte sur le dessous d'un wagon d'entretien de chemin de fer (22). Dans un premier mode de realisation, l'assemblage a poutres comprend une poutre interieure et une poutre exterieure (230', 230) recues l'une dans l'autre de maniere telescopique avec des bras de calage des traverses, actionnes hydrauliquement (102a, 102b), montes sur les extremites opposees eloignees de l'assemblage a poutres. Un cylindre hydraulique 'push/pull' (240) possede son belier et son cylindre relies, respectivement, aux poutres interieure et exterieure. Des goupilles de verrouillage actionnees hydrauliquement (238, 238') montees sur le berceau de support sont actionnees selectivement pour verrouiller soit la poutre interieure soit la poutre exterieure sur son berceau de support respectif. Lorsque la poutre interieure est verrouillee sur son berceau de support et que le cylindre hydraulique 'push/pull' est actionne, la poutre exterieure non verrouillee peut se detendre et se retracter pour enlever et changer les traverses de chemin de fer (T) d'un cote de la voie ferree et, lorsque la poutre exterieure est verrouillee sur son berceau de support et que le cylindre hydraulique 'push/pull' est actionne, la poutre interieure non verrouillee peut se detendre et se retracter de l'autre cote de la voie ferree. Dans un autre mode de realisation, l'appareil de changement des traverses (500) est monte sur une tourelle (502) pour permettre une rotation commandee autour de l'axe vertical. Le dispositif de changement de traverses de chemin de fer est compact, d'un fonctionnement simple, et peut etre utilise pour enlever les traverses d'un cote de la voie ferree ou de l'autre.

Abstract: New macroporous alkylaminophosphonic chelating resins which exhibit excellent mechanical stability and strength and good chemical stability are characterized by having an apparent density of 0.35 to 0.425 g/ml, a granulometry smaller than 0.8 mm, a water retention of 50 to 60 percent in the acid form, a porosity of 800 to 1100 mm 3 /g, a total theoretical capacity for the fixation of calcium ions of not greater than 31 g/l of resin in the sodium form and an osmotic resistance such that more than 90 percent of the beads are intact after 30 shocks. The high resistance to osmotic shock combined with an adequate exchange capacity exhibited by the new resins makes them particularly suitable for use in highly concentrated solutions, such as concentrated electrolytic brines. 
     A simple, effective, and economical procedure is described which makes it possible to eliminate, in the form of complexed cations, the impurities contained in the brines used for the electrolytic production of chlorine or alkali metals in membrane cells or diaphragm cells and for the electrolytic production of chlorates.
