Title: Moulin a cafe
Inventor: CAILLIOT SERGE L L
IPC: A47J42/36

Granted: 1979-06-05
Abstract: L'invention concerne un moulin à café comportant une vis de broyage verticale de forme générale cylindrique, munie d'au moins une gorge de profondeur progressivement décroissante jusqu'à une valeur nulle depuis son extrémité supérieure jusqu'à son extrémité inférieure, et susceptible de coopérer avec une enceinte de broyage tronconique de section décroissante vers le bas et de section horizontale éventuellement elliptique se prolongeant par un alésage cylindrique de hauteur notable servant au guidage de la partie inférieure de ladite vis.  Le moulin est caractérisé par le fait:  que le pas de ladite gorge, de forme générale hélicoïdale et de profondeur progressivement décroissante vers le bas, décroît également de façon progressive vers son extrémité inférieure, jusqu'à une valeur nulle; que l'alésage cylindrique précité est en communication avec au moins deux rainures externes diamétralement opposées, ménagées dans la paroi cylindrique dudit alésage et de faible profondeur radiale, rainures s'étendant sur une hauteur notable, et dont l'une au moins traverse, au voisinage de sa partie inférieure, un évidement  ménagé dans ladite paroi cylindrique, et prévu pour recevoir la partie supérieure d'une goulotte de descente de café moulu par gravité; et que la section horizontale de la partie supérieure de ladite enceinte de broyage forme au moins deux lobes séparés par des nervures internes.  Ce moulin à café est susceptible de fournir une mouture de café homogène, n'ayant subit qu'un échauffement négligeable, et n'ayant pas perdu en conséquence, au cours du broyage, une partie notable des produits aromatiques contenus dans le café non moulu.

Abstract: Abstract of the Disclosure The invention relates to a process for the cyclic electrochemical processing of pickle waste liquors containing maximum 100 g. of sulfuric acid and minimum 25 g. of iron ions per litre, combined with the pickling of iron.  According to the invention the ammonium, magnesium or alkali metal sulfate concentration of the waste liquor is adjusted to 0.5-1.0 mol./l. by introducing an appropriate salt, and the acid content of the waste liquor is reduced to a value not exceeding 100 g. of sulfuric acid/litre.  Then the waste liquor is fed into and passed through the cathode chambers of a series of dual electrolytic cells with diaphragms, wherein the iron content of the waste liquor is reduced to a value of 7-15 g. of Fe2+/litre.  Thereafter the-waste liquor is fed into and passed through the anode chambers in parallel with the cathode flow, and a current density in 15-22 A/dm2. of diaphragm surface and an electrolysis temperature of 70-90°C is maintained.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention is a synthetic textile filament having a novel configuration comprising three or more rounded projections or lobes, which provide desired bulk and soil-hiding properties, and two or more substantially flat sides, which provide desired luster.  In cross section, the surface of the filament is a continuum of alternating convex and concave arcs of different radii of curvature, as a result of which any distortions in the shape of the filament --e.g., during spinning and/or texturing operations -- do not result in substantial changes in bulk or in luster, which would be manifested as streaks in fabric constructions subsequently prepared there from.

Abstract: Abstract of the Disclosure The invention relates to resilient sealing bodies of flexible fibrous heat resistant material.  Such bodies are used on either hori-zontal or vertical sealing surfaces in high temperature applications. The fibrous materials of the sealing bodies are compressed and retained in the compressed state with suitable flexible holding means.  The bodies are suitable for the replacement of horizontal sand seals in high temperature usage and may be used equally well in applications which are impractical for sand seals, such as vertical and overhead applications. The sectional construction and flexibility of the sealing bodies permit their ready application and adjustment to give the optimum degree of sealing action as required in high temperature equipment.
