Inventor: LOVE SCOTT D
IPC: C07C2/54
Filed: 1991-02-18
Abstract: Méthode et appareil améliorés pour la manipulation en toute sécurité d'un catalyseur d'alkylation.  La méthode et l'appareil utilisent une cuve de procédé, qui a une double fonction : stocker le catalyseur d'alkylation et remettre en contact le produit hydrocarboné d'alkylation avec le catalyseur d'alkylation.  On fait passer l'alkylat produit à travers un dispositif éjecteur-mélangeur, qui mélange intimement l'alkylat avec le catalyseur.  Ce mélange passe dans la cuve de remise en contact à double fonction, où il y a séparation de phase du catalyseur et du produit hydrocarboné d'alkylation.  Des conduits relient le réacteur, l'échangeur thermique de refroidissement, le décanteur et la tuyauterie d'interconnexion de façon à permettre la libération rapide de la pression dans la cuve de stockage et de remise en contact, et le drainage ultérieur du catalyseur dans la cuve par la force de gravitation.  La méthode et l'appareil utilisent un système physique et un procédé d'alkylation permettant l'emploi d'une cuve de sécurité à la fois pour le stockage du catalyseur d'alkylation et la remise en contact du produit hydrocarboné d'alkylation.  L'appareil et la méthode sont sécuritaires, car ils permettent le transfert du catalyseur par drainage à partir des cuves du procédé d'alkylation dans la cuve de stockage sous le seul effet de la force motrice de l'énergie gravitationnelle.

Title: Process and apparatus for emissions reduction from waste incineration
Inventor: KHINKIS MARK J
IPC: F23G5/50
Filed: 1991-02-25
Abstract: A furnace for combustion wherein a combustion chamber is configured such that waste can be advanced from a drying zone, to a combustion zone, to a burnout zone, and then into an ash pit.  An air source provides air for drying, combustion and burnout in a primary combustion zone (PCZ).  Fuel or a fuel/recirculated flue gas mixture is injected above the PCZ to create a mostly reducing substoichiometric secondary combustion zone (SCZ), to reduce NOx and decompose other nitrogen bearing compounds entering the SCZ.  Vitiated air is injected into the combustion chamber above the mostly reducing SCZ.  A process for combustion of the waste includes introducing the waste into the combustion chamber, advancing the waste through the combustion chamber, supplying combustion air to the combustion chamber for drying and combusting the waste and final ash burnout, and removing ash products from the combustion chamber.  The fuel or fuel/recirculated gas mixture is supplied into the combustion chamber to create substoichiometric conditions for NOx reduction and nitrogen bearing compounds decomposition.  Overfire air is supplied into the combustion chamber above the substoichiometric zone for thorough mixing and at least partial burnout of combustibles contained within the waste/fuel combustion products.

Title: Dissolving a gas in a liquid
Inventor: FITZPATRICK NICHOLAS B
IPC: B67D1/00
Filed: 1991-03-11
Abstract: ABSTRACT DISSOLVING A GAS IN A LIQUID   Carbonated ale is pumped by pump 50 through a device 52 for dissolving a mixture of carbon dioxide and nitrogen therein.  The partial pressure of carbon dioxide in the mixture is selected so as to maintain or achieve a chosen concentration of carbon dioxide in the ale.  The ale passes to a tank 56 in which it is held for at least 10 minutes under a nitrogen pressure.  The ale is then passed to a filler from which it is charged into flexible, thin-walled cans which are then closed.  In each can, after its closure, dissolved gas comes out of solution to create therein a superatmospheric internal pressure that resist deformation of its walls during normal handling.

Abstract: In a procedure for determining registration errors on a printed product provided with register  marks, in which the  register  marks  undergo  opto-electrical  scanning when the printed product passes through the printing machine, and in which the register marks undergo two scannings  along  the  web  whereby  the  scannings  are separated by a predetermined time interval. A further signal  is  produced  by  subtraction  of  the  signals obtained  through  the  scanning  operation.  The  time-dependent  position  of  the  extreme  value  of  the additional  signal  makes  it possible  to measure  the position of the register mark.

Abstract: A gate valve assembly is disclosed which has two body housing members with coaxial through passages which are connected together in end-to-end relation. The housing members have a gate slot and a seat portion slot located beneath the gate slot. Resilient sealing means are located between the body housing members and are compressed by the opposed housing members to form a liquid-tight seal along the sides of the valve. Two resilient valve liners are fitted within the housing members, each has a body with a cylindrical through passage and a generally cylindrical outer surface which engages within the through passage of the housing member. The body has a planar front face and a seat portion which extends downwardly from the body and increases in thickness as it extends from the body. The valve liners are adjacent one another within the housing member such that the planar front faces of the valve liners are adjacent and in contact with one another and the seat portions are compressed within the seat portion slots to produce a tight seal along the bottom of the valve. A packing chamber formed by the two housing members is located above the valve liners and is filled with a packing material compressed by a packing compressor to form a tight seal around the gate. An imperforate gate is slidable through the gate slot between a valve open position and a valve closed position wherein the gate is interposed between the valve liners to prevent any fluid flow. The packing material, the side sealing means, and the seat portions for a liquid-tight seal in both the valve open and valve closed positions. The seat portions extend to the bottom of the valve such that particles trapped between the seat portions may be expelled from the valve between the seat portions.
