Title: Echangeurs thermiques formant automatiquement une enceinte
Inventor: WU ALAN K
IPC: F28D9/02
Filed: 2000-02-04
Abstract: On réalise des échangeurs thermiques formant automatiquement une enceinte, au moyen de plaques empilées (16, 18, 20, 22) présentant des rebords périphériques surélevés (96) sur un de leurs côtés et des crêtes périphériques continues (88) sur leur autre côté, de manière à ménager, lors de l'assemblage des plaques, et entre celles-ci, des canalisations d'écoulement alternées totalement fermées. Ces plaques présentent des bossages surélevés (72, 74, 76, 78) définissant des orifices à fluide (87, 86, 85, 84) s'alignant dans les plaques empilées, afin de former des collecteurs destinés à l'écoulement des fluides échangeurs de chaleur à travers les plaques alternées. Des barrières du type nervure (49, 92, 106, 135, 136, 144, 146, 158, 160, 168, 190, 216, 260) et du type gorge (50, 100, 108, 140, 141, 147, 148, 170, 172, 174, 192, 242, 262) sont formées dans les plaques à l'intérieur des bords et crêtes périphériques. Ces barrières empêchent un écoulement en court-circuit sur un côté des plaques et favorisent l'écoulement vers les zones à distance situées sur chaque côté des plaques, afin d'améliorer l'efficacité globale de ces échangeurs thermiques.

Abstract: L'invention concerne un procédé d'extraction d'un métal de base, tel que Ni, Co ou Zn, d'un minerai sulfuré ou d'un concentré renfermant du cuivre et le métal de base. Ce procédé comprend l'étape consistant à soumettre le minerai ou le concentré à une oxydation sous pression en présence d'oxygène et d'une solution acide renfermant du fer sous la forme d'halogénure et de sulphure, aux fins d'obtention d'une solution renfermant du cuivre et le métal de base. Cette solution est soumise à un procédé d'extraction de cuivre permettant de récupérer du cuivre de la solution et la solution renfermant le métal de base après récupération du cuivre est remise en circulation ou recyclée vers une étape d'oxydation sous pression, de manière à accroître la concentration en métal de base dans la solution. Un flux scindé de la solution est, de préférence, traité aux fins de récupération du métal de base.

Abstract: WEB EMBOSSING MACHINE                          ABSTRACT    The web embossing machine of the present invention  has two embossing  cylinders brought  close to  one another  for combining two  paper webs  by the  pressure contact  between mutually corresponding  protrusions on  the two  cylindrical surfaces. The  protrusions  are  in  rows  which  present  a pattern inclined  relative to  the  axes of  the  respective cylindrical surfaces,  i.e.,  in a  helicoidal  fashion  and relative to  a plane  passing at  right angle  through  said axes, and thus achieve a subsequent and progressive  contact instead of a  simultaneous contact throughout  the row.  The inclination relative  to  a plane  passing  at  right  angle through the cylinder axis avoids repetitive pressure actions on the  pressure  rollers  cooperating  with  the  embossing cylinders.

Title: Kind of engine
Inventor: PETKOV VESSELIN
IPC: H02K21/00
Filed: 1991-06-04
Abstract: ABSTRACT       Originally using concrete cases of gravitational, electrostatic and magnetic interactions, several versions of a new kind of engine are proposed. When the smaller of two plates is set under a given angle with respect to the bigger one, trying to be in an energetically optimal state, it strives to take a perpendicular or a parallel position to the bigger plate depending on whether the plates interact gravitationally, electro-statically when they are charged or magnetically when they are plate-shaped permanent magnets the poles of which are on their larger surfaces or one of the plates is such a magnet and the other is made of a ferro-magnetic material. This configuration of interacting plates is realized in several versions of the new engine. The main parts of the engine are a given number of plates and a ring-shaped part for a disk) playing the role of the bigger plate. The plates are fixed under an angle round the disk or round either the inner or the outer surface of the ring-shaped part.
