Abstract: In a method for the preparation and the distribution of two pumpable cattle feed mixtures of different composition to feeding places (35), a first and a second feed mixture having a first and second recipe, respectively, are simultaneously prepared in separate weighing-mixing tanks (1a, 2a) and dispensed in portions through separate main-supply lines (14a, 14b) and a feeding line (25), supplied by the latter, to feeding places (35) via branches (28-33) able to be freed successively. In this arrangement, use is made of a displacement fluid which fills the pipelines before the beginning and after the end of a feeding operation and displaces a feed column situated in the feeding line (25) or is displaced by said feed column, the displacement of feed by displacement fluid and vice versa being brought about in each case by a hydraulic pressure drop derived from the pump pressure and the generation thereof being effected by a central, computer-controlled switching unit (90). The two feed columns situated in the feeding line (25) are kept apart from one another at their mutually adjacent ends by a central separating member (71) axially displaceable in the feeding line and are kept apart from the displacement fluid at their respectively opposite ends by outer separating members (70, 72) likewise axially displaceable, and the separating members (70-72) are moved, individually, or two or three at a time, into preset changing operating positions, and fixed in these positions, by pressure increase and pressure reduction in the displacement fluid or in the feed columns. <IMAGE>

Abstract: ADU is prepared in particle form directly by reacting ammonium gas with liquid droplets of atomized uranyl compound solutions. Generation of liquid filtrate is prevented by using concentrated solutions of uranyl compounds as feeds, or drying the wet ADU particles formed before their settlement when a feed of low concentration is used. The ADU particle thus prepared is finely divided and easy-handling. No filtration operation is necessary in the preparation The UO₂ powder consequently obtained after calcining and reduction has consistent quality from batch to batch and has good pelletizing and sintering properties. Uranium dioxide with low fluorine content can be prepared from uranyl fluoride solution. Gadolinium-uranium oxide can also be prepared with the present method using an aqueous mixture of gadolinium nitrate and uranyl nitrate as a feed solution.

Abstract: The device has a single truncated-cone braking body (12), supported by an elastic member (13) coaxially and frontally with respect to a drum (TA) of the unit and is actuated by the elastic member so that it engages, with an elastic contact, against the drum along a circumference (C1) thereof which is smaller than the maximum circumference of the drum. The thread (F) slides between the drum and the braking body and extends from a point of contact with the drum and braking body along a path which is inclined with respect to the axis of the drum (TA), so that the tension produced by the braking body has at least one axial component (           H     ¯           a) which is discharged onto the braking body and is balanced by the elastic member. Increase in the tension on the thread produces, or tends to produce, by virtue of the corresponding increase in axial component, separation of the braking body from the drum with a corresponding self-adjusting braking action.
