Granted: 2001-10-09
Abstract: The invention relates to a stirring mill in whose grinding tank, provided with an inlet and an outlet, and charged with a load of grinding beads, a stirring shaft(stirring mechanism) provided with stirrers, is rotatable, on which, for holdingback the grinding beads a separator is mounted ahead of the outlet and is provided with radial openings.   The invention is addressed to the problem of creating a stirring mill with a grinding bead separator whose separation limit corresponds to the upper grain size of the fines, by which sieves or filters for holding back the grinding beads areavoided, and which nevertheless sufficiently assures that no grinding beads or particles of dispersants can enter into the finish-ground product.   This problem is solved by the fact that the separator is formed by a rotor in the manner of a centrifugal force sifting rotor (6) wherein the passages are formed by the interstices or spaces between every two sifter rotor paddles (10).

Title: Appareil destine a couper des vegetaux
Inventor: ZILLY GUENTER
IPC: A01D34/73
Filed: 1995-01-31
Granted: 2000-11-21
Abstract: Un appareil destiné à couper des végétaux comprend un fil de coupe (36, 38) qui tourne autour d'un axe de rotation et qui est enroulé sur une bobine (13). Une coulisse (16) verrouille de manière amovible la bobine (13) au moyen d'une came (26) par rapport à des éléments de mise en rotation. En déverrouillant la bobine (13), on peut rajuster la longueur de l'extrémité libre (37, 39) du fil de coupe (36, 38). Lorsque le fil de coupe (36, 38) est raccourci, les éléments de mise en rotation tournent plus vite et la coulisse (16) est déplacée par la force centrifuge vers sa position de déverrouillage. Afin de simplifier le rajustement du fil de coupe et d'améliorer son fonctionnement, la coulisse (16) est maintenue dans sa position de verrouillage uniquement par l'équilibre des forces d'appui des masses qui s'exercent entre sa came (26) et une butée (28) côté bobine, et peut être déplacée vers sa position de déverrouillage par la force centrifuge, de sorte que la bobine (13) puisse tourner par rapport à la partie creuse (10). La came (26) est remise dans la position de verrouillage par la force d'appui des masses qui s'exerce sur une surface de guidage (62) côté bobine. La surface d'appui (250) de la butée (280) prend un contour de plus en plus plat à mesure que son écartement radial par rapport au centre de la bobine (12, 112) augmente.

Abstract: A downhole control system for a production well is associated with perma- nent downhole formation evaluation sensors which remain downhole throughout production operations. These formation evaluation sensors may include, for e xam-ple, neutron generator, gamma ray detector and resis tivity sensors which can, inreal time, sense and evaluate formation paramete rs including important information regarding formation invading water entering the producing zone. Significantl y, this information can be obtained prior to the water actually entering the produci ng geo- logical formation and therefore corrective action (i.e., closing of a valve or sliding sleeve) can be taken prior to water being produced. This real time acquisiti on of formation data in the production well constitutes an important advance over current wireline techniques in that the present invention is far less costly and can anticipate and react to potential problems before they occur. In addition, the formatio n eval- uation sensors themselves can be placed much closer to the actual formation a.e.adjacent the casting or downhole completion tool) th an wireline devices which are restricted to the interior of the production tubing.

Abstract: A plug is used in welding a female-threaded boss into a hole through a part, the plug being installed in the boss prior to welding (preferably at the plant of the supplier of the bosses, so that they already have the plug installed when they arrive for welding).  The plug has a head and a cylindrical portion extending below the head, the cylindrical portion having male threads adapted to be received by the female threads of the boss.  The head has a minimum transverse dimension of at least the maximum transverse dimension of an upper surface of the boss so as to completely cover the upper surface.  The cylindrical threaded portion of the plug has thread-cutting edges defined therein, configured to re-tap the threads of the boss when an installed plug is rotated in the direction necessary to remove the plug from the boss.  The head of the plug has a recess therein, having two portions, namely an upper circular recess, and a lower hexagonal recess, the circular recess being configured to receive a tool to permit the plug to be held in place while the weld is effected, and the hexagonal recess permitting a tool to be inserted once the plug is no longer needed, so that it can be unthreaded from the boss.  Optionally, a copper cup washer may be used, the cup washer being configured to fit between the head and the boss, with the cup portion extending upwardly away from the boss, to isolate the head and the plug from the boss, thereby reducing any likelihood of the plug and the boss being accidentally welded together.
