Patent EP-0345959-A1 (EP)
Inventor: NEBELL HANS GEORG TIDEMANN
IPC: C25C3/16
Filed: 1989-05-22
Abstract: A potline for the electrolytic production of aluminium comprises rows of reduction cells with the cells arranged transversely in each row, each cell having at least one conductor (R) projecting through the bottom of the cell for each carbon cathode block. About half of the electric current is conducted to a cathode collector busbar (B1) and the other half to another collector busbar (B2). The cathode collector busbars (B1,B2) are disposed underneath the cell adjacent each of its long sides. Electric current from the collector busbar (B1) which is disposed at the largest distance from the next cell in the row, is conducted to the next cell via two busbars (K1,K6) provided at the short ends of the cell and via one or more pairs of busbars provided underneath the cell. The two busbars (K1,K6) at the short ends of the cell may have a cross section enabling them to conduct about twice as much current as each of the busbars being provided underneath the cells.

Abstract: The guardrail window assembly includes a window sub-assembly movable between the floor and ceiling sections of a patio or balcony. A stationary support is mounted on the floor and includes two foreshortened vertical supports rising only partially towards the ceiling section. A crossheader frame (40) is movably retained between the two vertical supports. The crossheader frame (40) is generally rectangularly shaped and the sides of the crossheader carry trolleys that run in tracks provided within the stationary support. In a first position, as shown in window modules (20, 22, 27), the crossheader frame is encased by the stationary support. In a second position, the crossheader frame extends from and frames an area between the stationary support and the ceiling. That area can be open or can be screened, as necessary. A window, consisting of a window pane and a window frame, is movably retained within the crossheader frame and the stationary support. In the first and second positions, the window is disposed within the stationary support. In a third position, as shown in window modules (23, 24, 25) the window is encased by the crossheader frame (40) and therefore closes the framed area. The guardrail window assembly also includes a motor and a pulley drive system for moving the crossheader frame (40) and the window sequentially through the first, second and third positions with respect to the stationary support.

Abstract: Dans les procédés et les appareils de photographie mammographique décrits, le sein (M) à photographier est comprimé, de façon à s'allonger, entre des plaques (6, 7) fixées à l'appareil photographique. Un faisceau (R) de rayons X est dirigé dpeuis l'un des côtés des plaques (6, 7) à travers le sein (M) placé entre les plaques jusqu'à un organe de représentation (21) placé du côté opposé des plaques par rapport à la source (2) des rayons X, l'organe de représentation étant placé à l'intérieur d'une cassette de film ou similaire disposée en connexion avec la structure de l'appareil. Pour permettre la photographie d'un sein (M1; M2; M3) en différentes projections (f; g; h), la partie de structure (25) de l'appareil dans laquelle sont montés la source des rayons X, l'organe de représentation (21) ainsi que les plaques (6, 7) de compression des seins effectue un mouvement de rotation autour d'un axe (b-b) qui coïncide sensiblement avec l'axe central (a-a) du sein (M) à photographier, qui est comprimé par les plaques (6, 7). La présente invention a pour but notamment de faire en sorte que la personne qui est photographiée n'ait pas besoin de bouger et que la hauteur de l'appareil n'ait pas besoin d'être modifiée, au moins pas de façon sensible, lorsqu'on change de projection ou de mode de photographie.

Abstract: A mechanism for mounting a generally circular, hollow pipe (54) coaxial with a machine tool has a central shaft (10) with a dome-­shaped head (12). A number of fingers (20) are equi-angularly spaced about the shaft (10) and pivoted at one end on the head (12). The fingers (20) in effect form a segmented cone. A collar (24) is slidably mounted on the shaft (10) and is coupled to the fingers (20) by respective connecting members (30) such that sliding movement of the collar (24) towards and away from the head (12) pivots the fingers (20) radially of the shaft (10). In use, the open end of the pipe (54) is located over the mechanism and the position of the collar (24) adjusted to expand the fingers (20) to grip the inner wall of the pipe (54) and hold the pipe firmly coaxial with the shaft (10). The end of the latter remote from the head (12) is secured to a machine tool axis to enable accurate machining of the pipe (54) by suitable tools which are mounted for movement about the machine tool axis.
