Title: Hot-fillable, blow-molded plastic container having a reinforced dome
Inventor: OGG RICHARD
IPC: B65D79/00
Filed: 1997-07-10
Abstract: A hot-fillable, blow-molded plastic container having a reinforced dome which controls dome distortion otherwise caused by forces associated with hot-filling and shipping. In one embodiment, the reinforced dome resists distortion, and in a second embodiment, the reinforced dome enhances ovalization distortion. The container dome is bell-shaped with an inwardly extending waist and has a plurality of vertically extending grooves passing through the waist. Each groove is inwardly concave and extends from below the waist to adjacent the finish. Arcuate lands are formed between the grooves, and optionally, can have panels with a textured pattern which add to the aesthetic appearance of the container and which provide further stiffening of the dome. When two grooves are utilized, ovalization distortion is enhanced, and when three or more grooves are utilized, distortion is prevented.

Patent CA-2218030-A1 (CA)
Title: Valve having pressure equalizing conduit
Inventor: DOMYTRAK WALTER
IPC: E21B33/06
Filed: 1997-10-10
Abstract: Pressure can build up on one side of a valve bore sealing mechanism when it is closed. This can make the mechanism difficult to open. A bore network is provided which extends through the valve housing side wall from the inlet end of the valve bore to its outlet end. The network bypasses the sealing mechanism and its sealing areas. Needle valves, operative from outside the valve, are used to open or close the network. The network can be temporarily opened to enable pressure to equalize across the closed sealing mechanism, thereby freeing the mechanism so that it can be turned.

Title: Procede et installation pour la trempe de panneaux de verre
Inventor: LISEC PETER
IPC: C03B29/12
Filed: 1997-03-10
Abstract: Une installation pour la trempe de panneaux de verre comprend une zone de préchauffage (1) dans laquelle sont chauffés plusieurs panneaux de verre (7) empilés debout dans des chariots à compartiments (6) à une température (p. ex. 300·) inférieure à la température de trempe de 650 ·C par exemple. A partir de cette zone de préchauffage (1) les panneaux de verre préchauffés (7) sont séparément déplacés vers une zone de chauffage (2) dans laquelle ils sont chauffés à la température de trempe, tout en étant disposés de façon à former un angle aigu par rapport à la verticale et maintenus entre deux plaques de chauffage par des coussins d'air. Sur le bord inférieur des deux plaques de chauffage de la zone de chauffage (2) se trouve un dispositif de transport qui soutient les panneaux de verre (7) simultanément vers le bas. Les panneaux de verre (7), chauffés à la température de trempe, sont amenés dans une zone de refroidissement (3) qui comporte des plaques de refroidissement parallèles aux plaques de chauffage, entre lesquelles le panneau de verre (7) est inséré pour la trempe. Les plaques de refroidissement peuvent aussi être appliquées pour la trempe sur les deux côtés du panneau de verre à tremper (7). Les panneaux de verre trempés dont la température atteint encore par exemple 300 ·C, sont transportés vers une zone de refroidissement postérieur (4) dans laquelle ils sont refroidis pour être déposés dans des chariots à compartiments (6) et portés lentement à la température ambiante. Dans la zone de chauffage (2) et la zone de refroidissement (3), les panneaux de verre (7) ne sont pas posés horizontalement, mais obliquement, ce qui facilite leur soutien et leur transport. Grâce au préchauffage et au refroidissement communs des panneaux (7) à la température ambiante après la trempe, on réalise une économie considérable d'énergie, puisque la puissance de chauffage ou de refroidissement dans les zones de préchauffage (1) et de refroidissement postérieur (4) peut être minime.

Title: Composite coiled tubing end connector
Inventor: SAS-JAWORSKY ALEXANDER
IPC: F16L33/22
Filed: 1996-09-26
Abstract: A connector is disclosed for use with composite spoolable pipe such as for use in well logging and workover operations in oil wells. The pipe which is spoolable is comprised of an outer composite structure containing several plies of high strength and stiffness fibers embedded in a resin material such as epoxy. The fibers are oriented to resist internal and external pressure and provide low bending stiffness. Fibers of high strength and modulus are embedded and bonded into a matrix that keeps the fibers in position, acts as a load transfer medium and protects the fibers from environmental damage. The plastic binder in which the fibers are embedded to form the matrix will have a modulus of elasticity (hereinafter modulus) that exceeds 100,000 psi. Typically, a liner may be employed in the pipe to serve as a structural member, one function of which is pressure containment to resist leakage of internal fluids within the tubing. A wear surface is employed as an outer layer and may be comprised of a binder containing particles of a tough material. The connector comprises a housing (31), a load collar (35), seal carrier (47), teethed ferrule means (39) and load support sleeve (49). Housing and load sleeve are screwed together so that teeth of the ferrule bite into the coiled tubing (15). Load support sleeve prevents the tubing from collapsing. The seal carrier has seals (53, 54) to seal against the end of the tubing and against housing (31).
