Title: Perfectionnement d'un procede thermodynamique de separation de constituants lourds du gaz naturel
Inventor: STOTHERS WILLIAM
IPC: F25J3/02
Filed: 2000-02-18
Abstract: La présente invention concerne un procédé de séparation du propane, du méthane ou de l'éthane de gaz naturel. En l'occurrence, on utilise un atelier à tours de fractionnement (30) pour séparer les composants lourds en décharge en pied de colonne du gaz léger en décharge en tête de colonne. Cet atelier réunit au moins deux tours de fractionnement (21, 32) fonctionnant à des pressions différentes, de façon que le produit lourd de la tour haute pression (31) se détende avant introduction dans la tour basse pression (32). On prend le gaz de charge dont les constituants sont à une première pression et on le fractionne en une première fraction (23) et une seconde fraction (22), aucune fraction n'étant nulle. On introduit la première fraction (23) dans la tour. On prend seconde fraction (22) et on la comprime (45) à une pression supérieure à la première pression. On extrait de la chaleur de la seconde fraction (22) pour en obtenir une condensation. Après un sous-refroidissement de la seconde fraction comprimée, on la laisse se détendre à la première pression, et après détente, on l'introduit dans atelier à tours de fractionnement (30) de façon à obtenir un refroidissement des matières se trouvant dans l'atelier à tours de fractionnement (30). Ce procédé convient particulièrement aux systèmes alimentés en basse pression où l'introduction du gaz léger en décharge en tête de colonne se fait à moins de 100 psi et, de préférence, à moins de 75 psi.

Title: Systeme et procede de mesure de synchronisation a l'aide d'une ligne de retard vernier a invariance de composants
Inventor: ROBERTS GORDON W
IPC: G04F10/00
Filed: 2003-03-24
Abstract: Ces dernières années, bien des efforts ont été déployés pour améliorer les performances des dispositifs de mesure de synchronisation et d'instabilité au moyen de techniques à boucle à retard de phase (DLL) et de ligne de retard Vernier (VDL). Toutefois, ces techniques nécessitent des éléments extrêmement appariés afin de réduire les erreurs de synchronisation par non linéarité différentielle. Dans le but de réduire les exigences en matière d'appariement d'éléments, on a mis au point, dans le cadre de cette invention, une technique VDL à invariance de composants qui permet de synthétiser le dispositif de mesure à partir d'une description RTL. La présente invention repose sur une structure VDL mono-étagée servant à imiter le comportement d'une VDL complète. Par ailleurs, et compte tenu de l'importance du temps dans les essais de production, l'invention porte sur un procédé et un système propres à accélérer de tels essais en recourant à un surcroît de matériel supplémentaire.

Title: Process for removing liquid containing chlorinated organic compounds from liquide-impregnated components of appliance and apparatus for carrying out said process
Inventor: HIRTH MICHAEL
IPC: H01F27/14
Filed: 1989-10-31
Abstract: ABSTRACT OF THE DISCLOSURE         The process is intended to remove chlorinated organic compounds such as, for example, PCBs from very inaccessible components  (core 3)  of appliances which contain, like transformers, such compounds as oil fill-ing, in an inexpensive and nevertheless environmentally compatible manner.        This  is  achieved  by releasing  the  chlorine-containing compounds in the presence of a reactant which binds the chlorine in the form of an alkali chloride and/or alkaline earth chloride. The metallic components of the appliances are consequently accessible for a re-cycling   process  in   an   extremely  environmentally compatible and economic manner.

IPC: B01F13/10
Filed: 1990-05-09
Abstract: Abstract of the Disclosure An apparatus for combining powdered and liquid constituents to form a slurry, comprises a first tank for initially holding a quantity of liquid and a second tank having an upper and a lower end.  A first conduit has a valve extending from the first tank to the second tank.  A control means responsive to the liquid level in the second tank closes the valve when the liquid in the second tank reaches a predetermined maximum level.  This maximum level is substantially lower than the full volumetric capacity of the second tank so that an open chamber is formed above the maximum liquid level.  A vacuum pump attached to the upper end of said second tank creates a reduced pressure in its open  chamber.    A  chamber  conveying  conduit  extending through the upper end of the second tank has a movable exterior section with an outer end opening and a fixed interior section within the second tank having an outlet extending slightly above the maximum liquid level so that a low pressure condition is created within the open chamber above the maximum liquid level and causes an airstream in the conveying conduit which enables powdered material to be sucked into the second tank as mixing occurs with liquid therein to form a slurry.

Abstract: Compromise of a predetermined secure data processing routine by a procedure known as a "clock attack" is prevented by a method that inhibits synchronization with externally generated instructions by preventing determination of the time of execution of the predetermined data processing routine in relation to occurrence of an externally observable event that precedes the execution of the predetermined routine. The method includes the step of (a) randomly varying the duration between the occurrence of the externally observable event and the execution of the predetermined routine.  Step (a) includes the steps of (b) executing one or more interim data processing routines between the occurrence of the externally observable event and the execution of the predetermined routine; and (c) randomly varying the duration of said interim routines. Steps (b) and (c) may include the step of (d) randomly assembling m said interim routines for said execution from a group of n stored routines having different durations, wherein m and n are integers, with n being greater than m. Step (d) may include either the step of (e) randomly accessing said m interim routines from a secure memory; or the steps of (f) randomly accessing pointers for said m interim routines from a secure memory;  and (g) accessing said m interim routines from a memory in response to said pointers.  Step (c) includes the step of (h) randomly varying the duration of the interim routines in response to dynamically processed data that does not repetitively recur each time said interim routines are accessed. The method further includes the steps of (i) monitoring said interim routines to detect whether said interim routines are being tampered with; and (j) preventing the execution of said predetermined routine in response to detecting that said interim routines are being tampered with.
