Abstract: A process and apparatus for controlling the rate of introduction and the content of alumina to a tank for the production of aluminium by the electrolysis of dissolved alumina in a cryolite-base bath, the upper part of which forms a solidified crust, and wherein the alumina content is maintained within a narrow range, of between 1% and 3.5%, wherein the alumina is introduced directly into the molten cryolite bath by way of at least one opening which is kept open in the solidified crust and the rate at which the alumina is introduced is modulated relative to variations in the internal resistance of the tank during predetermined periods of time, with alternation of the cycles of introducing alumina at a slower rate and at a faster rate than the rate corresponding to normal consumption within the tank.

IPC: B27F7/15

Abstract: Wooden structures are assembled from a plurality of wooden elements with interposed metallic connectors, by assembling the wooden elements on a work table provided with a rectangular grid. The image of the structure to be assembled, with a superposed grid corresponding to the grid on the table, is projected on the table until the respective grids register with each other. Then the wooden elements are assembled on the picture; and as the corners of the grid on the table are tapped holes, retainers can be used to hold the assembled elements in place. The table with thus-assembled wooden elements is then run through an endless belt press having superposed convergent runs, whereby the metallic connectors are sunk into the wooden elements to complete assembly of the structure, after which the completed structures are removed from the tables onto rollers with interspersed lifting arms that swing vertically about an axis parallel to the direction of movement of the tables. The arms are mounted on a carriage that moves horizontally perpendicular to the direction of movement of the tables to deliver a completed wooden structure to a stack and to return to receive the next structure.

Title: Machine volumetrique, en particulier machine a piston rotatif annulaire
Inventor: WILLIMCZIK WOLFHART
IPC: F01C1/34
Filed: 1982-08-02
Abstract: La machine volumétrique utilisée comme pompe, compresseur ou analogue est en principe assimilée aux machines à tiroir rotatif et à palettes, sauf en ce qui concerne le piston cylindrique qui est remplacé par un piston annulaire (1) disposé dans une chambre annulaire délimitée par des parois intérieures (3) et extérieures (4), qui divisent cette chambre annulaire en deux chambres de travail (2) et qui tournent, roulent ou sont au repos, lorsque les parois radiales de la chambre de travail sont en mouvement. Un piston cylindrique circulaire peut se mouvoir entre les parois radiales de la chambre de travail, qui engendrent le volume de travail, qui peuvent former un monoangle, un biangle ou un triangle, mais qui ont toujours la même distance radiale la plus courte. Ainsi, les éléments moteurs (12) (tiroirs (14) ou rouleaux cylindriques (13)) disposés dans des évidements radiaux (11) du piston (1), ont un mouvement obligatoire. Le piston est fixé à au moins un organe latéral (5). En annulant les forces centrifuges, cette machine se comporte comme une machine à piston rotatif. De chaque côté du piston est agencée une chambre de travail, créant ainsi une machine à deux étages, ce qui permet de ne pas toujours les exploiter obligatoirement; le mouvement obligatoire et l'annulation des forces centrifuges sont avantageux en soi. Inversément, un piston (monoangle, biangle, triangle...) qui engendre le volume de travail, peut tourner entre des parois cylindriques circulaires. Une pompe à anneaux excentriques est caractérisée par un piston annulaire qui roule simultanément sur les deux parois annulaires. Une paroi élastique peut être disposée entre le piston et le carter créant une pompe hermétiquement fermée qui résiste aux agents abrasifs. Le piston en forme de fer à cheval peut être stationnaire et les parois élastiques peuvent être entraînées par un excentrique.

Abstract: A chair for human dental or medical treatment and having an improved adjustable headrest support. The chair features a flat curved linear strip member (13) which extends between the headrest (12) and the main frame of the chair. The strip member (13) is guided by at least one and preferably two pairs of opposed cylindrical guide rollers (16) which contiguously straddle the strip member (13) so as to guide the motion of the strip member (13) along its longitudinal axis, as it is displaced along its axis and towards or away from the frame, typically by a hydraulic mechanism (7, 7a). This makes possible vertical direction of movement of the strip member (13). The hydraulic mechanism (7, 7a) or two mechanisms in tandem (7, 7a, 6, 6a) are a pivoted floating mounting for the strip member (13) which facilitates ready adjustment of the headrest support relative to the main frame and seat of the chair. At least one tension spring (11, 15) is provided to produce smooth backdown of the piston plunger (6a, 7a) and piston head when hydraulic fluid pressure in the cylinder (6, 7) is reduced.
