IPC: C07C2/54
Filed: 1991-02-18
Granted: 1999-01-19
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: Water saving device for toilets
Inventor: SCHMITZ PETER J
IPC: E03D1/14
Filed: 1992-05-29
Granted: 1996-06-25
Abstract: The water-saving devices for a toilet is of the type which float up and down on the overflow tube, where downward movement of the device brings it into contact with the flapper valve at the bottom of the toilet tank in order to close it prematurely, thereby reducing the amount of water used for the flush.  Upper and lower opposing cup shapes are integrally mounted around respective cylindrical sleeves, the sleeves being adapted to slide one within the other to adjust the spacing between the opposing cup shapes.  One sleeve has an inset area with a longitudinal row of spaced holes or indentations.  The other sleeve has an elongated tongue having a raised dimple which engages one of the spaced holes or indentations to set the spacing between cup shapes.  A number of ribs or vanes are molded as part of the upper cup, and act to deflect the float rod to reduce any possibility of the float rod catching under the upper cup.  The cup shapes are not cylindrical, but instead have flat vertical surfaces relatively close to the sleeves, so that the device can still be installed in tanks where the overflow tube is close to the tank wall.  A C-shaped shell snaps onto the lower cup and is rotatable between a first position in which it leaves the flat surface exposed, and a second position in which the lower cup in effect takes on a circular shape.
Patent CA-2084836-C (CA)
Inventor: TOMEK MARTIN L
IPC: E21B47/01
Filed: 1992-12-08
Granted: 1999-04-20
Abstract: The present disclosure is directed to a shock absorbing device for threading in a tubing string for running delicate instruments into a well borehole where they are in near proximity to explosives which might otherwise be detonate. This particularly is important in a well borehole which is filled with a standing column of liquid which transmits the shock waves quite readily. This is a separate assembly which can be threaded in the tubing string and has a pin and box connection for that. Moreover, it is formed of an outer mandrel surrounding connected inner upper and inner lower mandrels; the inner mandrels define annular spaces for receiving shock absorbers defined by alternating thin layers of metal and rubber; the metal and rubber washers have different shock wave impedances and tend therefore to absorb shock waves traveling either upwardly or downwardly in the well borehole.

A cam on the shaft engages a follower on the ring for rocking the ring from its out-of-service position into its connecting position at least once during each rotation of the shaft about the axis.
Patent CA-2085423-C (CA)
Inventor: STEKELENBURG MICHAEL ALWIN WIL
IPC: H04N5/376
Filed: 1992-12-15
Granted: 2001-10-02
Abstract: The invention relates to a charge-coupled imaging device whose width/height ratio is adjustable in that a number of columns situated in two strips on either side of the sensor are not used. The charge generated in these columns is placed in the horizontal output register simultaneously with the active information which is to be used, and is drained off in the flyback time between consecutive active line times through the or an output of the output register. Since the said non-active strips are situated on either side of the sensor, the location of the centre of the active portion of the matrix is fixed, independent of whether the information from the said strips is or is not used, so that in every state of the sensor this centre coincides with the optical centre of the optical system used.

Title: Interactive communication and transport system for still pictures
Inventor: HANNINA RITA
IPC: H04L12/28
Filed: 1991-06-21
Granted: 1997-07-29
Abstract: Interactive communication and transport system in which communication for the purpose of requests takes place between requesting receiving stations (B) and one or more request-processing transmitting stations (A) provided with a source (1-4) of information of separately specifiable bulk data via a relatively low-speed communication path in a first network (6), and the forwarding of the requested bulk data to receiving stations (B) specified in the requests by transmitting means (14-17) takes place in a packet-switched mode via a relatively high-speed transmission path in a second network (10). Supervisor means incorporated in the system assign temporary destination addresses to the receiving stations (B) for the forwarding and grant permission for forwarding to the transmitting workstations (A) on request; the actual forwarding takes place after a respective transmitting station (A) which has received permission has detected by means of 'end of packet' -detection means (18) that transmission of a previous packet has been completed. Advantages are that the data channel along which the picture data is transported is used more efficiently and that one-off forwarding of picture data to a group of destinations is possible both on request and dynamically from the system.
