Abstract: L'invention concerne un procédé de craquage catalytique, dans une zone réactionnelle en lit fluide ou entraîné, d'une charge résiduelle soumise à au moins un prétraitement. Ce procédé peut être utilisé notamment pour le raffinage des charges lourdes du pétrole. Le prétraitement est caractérisé en ce qu'une partie au moins de ladite charge sous forme vaporisée et une partie au moins des particules catalytiques circulent au moins dans une enceinte dans laquelle est établi un contact entre d'une part au moins ladite partie de la charge et d'autre part des particules de solides (catalytiquement peu actives) distinctes des particules catalytiques, lesdites particules de solides et ladite charge circulant globalement ensemble dans le même sens, soit de haut en bas, soit de bas en haut de ladite enceinte à une température sensiblement égale à la température qui règne à l'entrée de la zone réactionnelle. A l'issu d'un brassage entre au moins les particules de solides et la charge, celle-ci, débarrassée de la majeure partie des produits résiduels, est séparée des particules de solides et est envoyée avec les particules catalytiques dans la zone réactionnelle.

Abstract: A B S T R A C T            The invention concerns a three-edged tool (12) for a woodworking machine. The edges (18,19,20) of the tool are arranged with equal angular spacing about a tool body and protruding therefrom. In the surfaces (24,25,26) between the edges are recesses (27,28,29) which are shaped on one hand to retain the tool by mating engagement with a correspondingly shaped protrusion (30) provided on a tool carrier (10), on the other hand to act as a kerf in order to guide a break in case of overload of an edge (18) to the area between two recesses (27,28). Fastening means for the tool include a support part (14) provided on the tool carrier and a clamping part (15). The support part (14) carries the protrusion (30), which is shaped to engage in a recess (28) of the tool, and has a support surface (14') for supporting a clearance surface of an edge (19) which is inactive when the tool is mounted on the tool carrier. The clamping part (15) has a clamping surface (22) which is adapted to press against the clearance surface of the second inactive edge (20) of the tool.     Fig. 2

Title: Pipe liner process and apparatus
Inventor: LEDOUX PATRICK R
IPC: B29K23/00
Filed: 1988-07-08
Granted: 1993-01-19
Abstract: IMPROVED PIPE LINER PROCESS AND APPARATUS                 ABSTRACT OF THE DISCLOSURE      Method and apparatus are provided for lining a pipe wherein a thermoplastic liner is initially formed in a cylindrical shape with a diameter slightly larger than the internal diameter of the pipe.  The liner is temporarily deformed at an elevated temperature to a different cross-section, preferably U-shaped, to reduce its overall cross-sectional dimension to facilitate insertion into the pipe to be lined.  Once inserted, the pipe liner is reheated to the crystallization temperature of the thermoplastic material to cause the liner to return to its original cylindrical shape.  Pressure within the liner is also increased in two stages to cause the liner to conform to the interior surface of the pipe.  An expansion pig may also be employed to ensure even more exact conformance.  After expansion, ends of the liner which extend beyond the pipe are flared into engagement with the pipe flanges.     For lining pipe normally containing in service fluid under pressure, the liner, after insertion into the pipe, can be mechanically reformed to engage the interior wall of the pipe.  The normal service pressure is then used to maintain the liner in its generally cylindrical shape over the time necessary to completely relieve the stresses in the liner tending to cause the liner to return to its deformed shape.
