Title: Procede d'optimisation de tubes multi-couches en materiaux composites et tubes obtenus par le procede
Inventor: SPARKS CHARLES
IPC: B29L23/00
Filed: 1990-06-20
Abstract: Procédé pour l'optimisation des caractéristiques de tubes multi-couches en matériaux composites fibreux, permettant de maintenir dans des limites spécifiées les allongements et contraintes Limites qu'ils supportent en réponse à des efforts appliqués.        Le procédé comporte la sélection d'au moins deux paramètres optimisés caractéristiques de chaque couche (son épaisseur et l'angle de bobinage des fibres par exemple) en partant d'un tube initial choisi a priori. Par de petits écarts appliqués aux paramètres, on détermine les relations entre de petits écarts appliqués aux paramètres et les variations des allongements et contraintes limites qui en résultent, puis les relations inverses reliant les variations des allongements et contraintes limites et les écarts de paramètres. La connaissance de ces relations inverses permet, en une ou plusieurs étapes, de trouver les écarts à appliquer pour combler les différences mesurables entre les allongements et contraintes limites du tube optimisé et du tube choisi a priori.

Patent CA-2024347-A1 (CA)
Title: Sealing assembly for subterranean well packing unit
Inventor: LUKE MIKE A
IPC: E21B33/12
Filed: 1990-08-30
Abstract: In subterranean wells, it is common to effect the radial expansion of an annular organic sealing element into sealing engagement between a tubular inner body and the inner wall of a well conduit, such as a well casing. Extrusion of the organic material has been encountered between the inner surface of upper and lower cone elements and the exterior of a tubular body portion and also between the inclined surfaces of upper and lower cone elements and the cooperating surfaces of cone rings. The first mentioned extrusion path is eliminated by forming a generally radial surface on the inner end of the upper and lower cones and inserting a carbon fiber filled organic material in the resulting annular chamber. The extrusion path between rhe inclined surface of the cone and the cooperating surface of the cone ring is minimized by utilizing the forces exerted by the compressed sealing material of the packing element to effect the shearing of the vertex portion of a packer ring along a plane that corresponds exactly to the inclined surface of the cone rang.

Filed: 1992-05-14
Abstract: ABSTRACT OF THE INVENTION    A fluid pump for infusing medical fluids to a patient includes a housing having an inlet port and an outlet port.          The housing further includes a substantially hemispherically shaped surface which is circumscribed by a periphery.   An elastomeric membrane is attached to the periphery of the surface and  is  stretched over the  surface  to place the membrane in its region of nonlinear elasticity.  With this combination, a potential fluid chamber is established between the surface of the housing and the stretched membrane.    In operation, fluid is injected through the inlet port and into the potential chamber between the housing and the elastomeric membrane to fill the chamber with the desired medical fluid.  A fluid line is connected to the outlet port of the pump and a flow restrictor is coupled with the fluid line to control the flow of fluid from the chamber.  Fluid flows  from  the  chamber  as  a  result  of  the  nonlinear contraction of the elastomeric membrane. 10700.167                      -35-
