Patent ES-465170-A1 (ES)
Title: Waste material disintegrator
IPC: B02C18/14
Filed: 1977-12-16
Abstract: The device contains a rotor (5) which rotates in a housing (1) about a horizontal axis (2) and is fitted with tearing tools (4). At the distance (a) away from the impact circle (14) of the tearing tools there is a first anvil edge (26) which is part of a pressing wall (20). The pressing wall (20) lies in a plane which runs through the axis of the rotor and is inclined with respect to the vertical plane by 0 to 25 DEG . When comminuting cardboard boxes and large areas of cardboard difficulties often arise because these materials have the tendency to build up above the rotor in a vault-like shape at the side walls of the housing chamber and to form a bridge of material as a result of which the supply to the rotor is blocked. In order to destroy these material bridges, the pressing wall (20) can be pivoted between the position shown and a horizontal position, a second anvil edge (27) protruding, in the horizontal position of the pressing wall, as far as the aforesaid distance (a) towards the impact circle (14) of the tearing tools (4).

Title: Device to avoid the formation of fissures on the inner side of feedwater inlet nozzles of a pressure vessel.
IPC: G21C13/02
Filed: 1981-07-20
Abstract: Installation for preventing the formation of cracks at the inner surface of the sleeve of a water supply conduit (13) opening into pressure tanks, particularly a pressure tank of a nuclear reactor or a vapour generator. The feeding of the supply water in the water-vapour chamber (II), of a pressure tank (DE) is done by a portion of a mainly horizontal conduit (140) and by a portion of an ascending conduit (141) up to the overflow edge (Ü) of the end of the portion of the ascending conduit (141). From there, the supply water is mixed by means of a descending conduit piece (142) and possibly by a conduit ring which is attached thereto, in the middle in the water-vapour chamber (II) respectively in the pressure chamber (8) of the pressure tank (DE). Thereby, the formation of the different temperature layers from the water return current hotter in the sleeve is prevented. Further, it is important to maintain the ratio A<un>u/D<ui>u as small as possible. A ratio between 0.5 and 2 has proved to be feasible in practice. (A<un>n) is the horizontal distance of the inner wall of the pressure tank to the axis (M<uÚ>u) which passes by the gravity centre of the cross-section at the overflow edge (Ü). (D<ui>u) is the inner diametre of the water supply conduit opening into the pressure tank.
