Title: Procedes et appareil destines a des recipients de metal mis en forme par verin et par pression et a des elements similaires
Inventor: GONG KEVIN
IPC: B21D26/049
Filed: 2003-10-20
Abstract: La présente invention concerne un procédé de formage de récipient de métal en forme de bouteille ou de forme différente par la soumission d'une préforme de métal creuse (218) possédant une extrémité fermée à une pression de fluide interne de façon à entraîner une dilatation de cette préforme contre la paroi d'une cavité de moule (211) définissant la forme souhaitée, et par l'avance d'un poinçon (212) au moyen d'un vérin d'appui (214) dans cette cavité de moule de façon à déplacer et à déformer l'extrémité fermée de la préforme avant ou après le commencement de la dilatation mais avant le fin de celle-ci. L'étape de soumission à la pression est réalisée par la soumission simultanée de la préforme présente dans la cavité de moule à des pressions de fluide positives externes et internes commandables de manière indépendante et par la variation des différences entre elles afin de commander la vitesse de dilatation. Un appareil destiné à mettre en oeuvre ce procédé comprend un moule (210) à coins avec plusieurs coins (219, 221, 223) placés en tandem de façon à définir une paroi de cavité de moule et des éléments chauffants (231, 233), respectivement introduits à l'intérieur de la préforme et agencés de manière à chauffer le vérin d'appui.

Abstract: LOW DISTORTION LINEAR VARIABLE DISPLACEMENT TRANSFORMER    Abstract of the Disclosure A transformer and method for sensing displacement. A linear variable displacement transformer (LVDT) (50, 100, 150, 200, and 250) is disclosed with respect to several embodiments, each including a core (52, 102, 152, 202, and 252) having a primary leg (56, 104, 154, 204, and 254), and two secondary legs (58 and 60, 106 and 108, 158 and 160, 206 and 208, and 258 and 260). A primary coil (54,110, 156, 210, and 264) is disposed on the primary leg, and secondary coils (62 and 64, 112 and 114, 162 and 154, 212 and 214, and 266 and 268) are disposed on the secondary legs. Pole pieces (70 and 72, 120 and 122, 170 and 172, 222 and 224, and 274 and 276) are disposed in gaps between the primary leg and each secondary leg, so that they control the reluctance to a magnetic flux produced by an electric current flowing through the primary coil. Displacement of the two pole pieces within the gaps separating facing surfaces of the primary and secondary legs changes the proportion of the magnetic flux through each of the secondary legs and thus varies an electrical signal induced in each of the secondary coils. A differential between the electrical signals thus corresponds to the differentialdisplacement of the pole pieces in each of the embodiments.

Patent CA-2062825-A1 (CA)
Inventor: ZALTZMAN ARTHUR
IPC: B03B5/28
Filed: 1990-05-23
Abstract: A method and apparatus for sorting articles with small density differences utilizing a flotation stream. A separator is provided in which a flotation stream continuously flows through a trough and is used to effect the separation of a mixture of articles having small density differences into several groups. Each density group of the mixture of articles to be separated is introduced at the head of the flotation stream at a selected depth. In one embodiment, the flotation stream may be comprised of a fluidized bed which is created by forcing a gas upwardly through a fluidization medium such as sand. In another embodiment of the invention, the flotation stream may be formed from a liquid. Once the mixture of articles is introduced at the selected depth into the flotation stream near the head of the stream, since the density of the flotation stream is greater than the density of the articles, the articles of lesser density begin to ascend toward the top of the flotation stream while at the same time the articles are carried downstream by virtue of the velocity of the flotation stream. Articles having a greater density will be carried further downstream whereas articles having less density will ascend to the top of the stream at a point further upstream, thereby effecting a spacial separation of the articles based on their differing densities.
