Abstract: The invention provides a granulate comprising particles having sizes substantially within the range 0.15 to 1.25 mm, the granulate consisting of:(a) about 1 to 99 weight % of partially or completely hydrated sodium tripolyphosphate containing water of hydration in a proportion of at least about 10 weight %, based on the theoretically possible water content, the anhydrous sodium tripolyphosphate containing about 20 to 90 weight % of phase-I-material prior to its being hydrated, the balance being phase-II, and(b) about 99 to 1 weight % of a water-insoluble alumino silicate ion exchanger material of the general formula(Cat.sub.2/n O).sub.x.Me.sub.2 O.sub.3.(SiO.sub.2).sub.y.zH.sub.2 Oin which Cat stands for a calcium exchangeable cation with the valency n, x is 0.7 to 1.5, Me stands for boron or aluminum, y is 0.8 to 6, and z is 1.8 to 13.5.The invention also includes a spray process for making a granulate as just specified.

Abstract: The disclosure relates to a granulate with a particle size essentially of about 0.2 to 2 mm consisting of(a) about 2 to 95 weight % of a partially or completely hydrated pentasodium tripolyphosphate,(b) less than 3 weight % of an ammonium polyphosphate and the balance(c) being in the form of a water-insoluble aluminum silicate ion exchanging material.The granulate can be used in detergents.

Abstract: Electrical power of high intensity is transmitted to a rotating electrode with the use of an apparatus, wherein a shaft is provided with a connecting joint which is rigidly connected to a cylindrical container serving as the rotating electrode. A trough filled with a low-melting alloy has a contact maker secured to it, and the latter has a flexible cable screwed thereto. A cover, which has the shaft passed through it, is insulatingly placed on the cover, and the shaft is provided with a disk, in the region of the cover.
