Patent CA-2147608-A1 (CA)
Inventor: POMMIER YVES
IPC: C07D471/04
Filed: 1993-10-14
Abstract: Azatoxin and derivatives thereof of formulae B-D are illustrative of a new class of antitumor drugs that are topoisomerase II (top 2) inhibitors. The pharmacophore inhibits the catalytic activity of the purified enzyme but does not unwind relaxed or supercoiled DNA. It is nonintercalative and has at least two domains: a quasi-planar polycyclic ring system, which may bind between DNA base pairs, and a pendant substituent thought to interact with the enzyme, with the DNA grooves or with both. In SV40 and C-myc DNA, azatoxin induces numerous double-strand breaks according to a cleavage pattern which differs from those of known top (2) inhibitors. Azatoxin also is a potent inhibitor of tubulin polymerization.

Title: Method of treating water
Inventor: HEINIG CHARLES F JR
IPC: B01J23/50
Filed: 1994-03-30
Abstract: A method of treating water to kill bacteria therein includes exposing the water to a silver catalyst in the presence of oxygen to form an active oxidizer in the water. The silver catalyst includes elemental silver deposited on a high surface area alumina matrix. In one form of the method the active oxidizer formed is predominantly hydrogen peroxide, whereas in a second form of the method an oxidizable salt is added to the water so that the active oxidizer formed is predominantly oxidized ions of the salt. The method can be effectively carried out by adding oxygen in the form of O2 ozone to the water prior to exposing it to the catalyst
Patent CA-2159908-A1 (CA)
Title: Manufacturing matrices
Inventor: BJOERK SETH
IPC: A61K47/38
Filed: 1994-04-14
Abstract: The present invention is directed to a process for the manufacture of porous cellulose matrices with a defined particle size and a significantly higher porosity (i.e. pore volume) than conventional formulations, such as pellet formulations containing cellulose and binders. The process is applicable on a wide variety of substantially dry cellulose raw materials. The cellulose is mechanically treated with low adhesion to the process equipment during a controlled gradual addition of an aqueous based fluid, optionally containing a surface-active ingredient, into regular particles, which are finally dried to obtain dry porous cellulose matrices. The so obtained matrices can be used as carriers for bioactive substances in multiple-unit preparations or tablets.

Patent CA-2163293-A1 (CA)
Inventor: PAUL DUBOIS TAINE BENOIT
IPC: G06F9/46
Filed: 1995-11-20
Abstract: Ce protocole consiste notamment à attribuer, à une transaction modifiant des données stockées dans une mémoire (M), des verrous d'intention d'écriture au moment de l'accès. Ces verrous n'interdisent pas l'attribution de verrous de lecture à d'autres transactions. Les autres transactions peuvent donc lire les anciennes valeurs des variables tant que les nouvelles valeurs ne sont pas inscrites dans la mémoire (M), cette inscription étant faite au moment de la fermeture de la transaction. Le temps d'exclusion des lecteurs sur des données en cours de modification, est limitée à la durée de l'écriture des nouvelles valeurs dans la mémoire. Ce protocole est particulièrement avantageux dans le cas où la mémoire (M) est volatile et où les données modifiées sont sauvegardées dans une autre mémoire non volatile (D). Dans ce cas, le protocole consiste en outre à tenir à jour une table (T), mémorisée dans la mémoire non volatile (D), et contenant les identités des transactions en cours. Cette table permet d'assurer la cohérence des données après une défaillance de la mémoire volatile (M), tout en contribuant à maintenir un temps minimal d'exclusion des lecteurs sur des données en cours de modification. Application aux systèmes de commande de réseau de télécommunication.

Abstract: La présente invention concerne un convertisseur de fréquence permettant de convertir une fréquence intermédiaire finale en une fréquence de la bande de base. Un compteur (401) génère deux signaux logiques G1 (402) et G2 (403) qui sont envoyés à une porte OU exclusif (404) et un multiplexeur (406). Lorsque'un signal de commande (411) est démodulé, le multiplexeur (406) envoie le signal G1 à I1 et le signal G2 à I2. Lorsqu'un signal de commande (411) est modulé, le multiplexeur envoie le signal binaire G1 à I2 (410) et le signal G2 à I1 (407). De la même façon, en présence de la sortie de la porte OU exclusif est modulée, le multiplexeur (405) intervertit ses échantillons d'entrée réels et imaginaires; dans le cas contraire, il n'effectue aucune opération sur ses échantillons d'entrée. Les signaux I1 (407) et I2 (410) servent à commander les inverseurs arithmétiques respectifs (408, 409). Lorsque le signal de commande de l'un des deux inverseurs est modulé, l'inverseur concerné exécute l'inversion arithmétique; dans le cas contraire, il n'effectue aucune opération.

IPC: C09K23/00
Filed: 1996-02-29
Abstract: A suspending agent-containing slurry is disclosed which comprises a dispersant and a particulate suspending agent having a particle size distribution in which the particle diameter at weight-cumulative 95%, from the minimum particle size, is 1 µm or smaller.  A method for efficiently producing the suspending agent-containing slurry is also disclosed.

Patent CA-2177127-A1 (CA)
Inventor: GOLDENBERG ANDREW A
IPC: F16L55/28
Filed: 1996-05-22
Abstract: A system for feeding a cable into a pipeline or other conduit comprises a rotating turret and a local cable feeding mechanism for drawing the cable off of the turret reel and loading it thereon. A remote cable feeding mechanism for inserting the cable into or withdrawing it from the pipeline is attached to a launch saddle secured to the pipeline, and its feeding rate is synchronized with that of the local cable feeding mechanism. Where the cable acts as an umbilical cable carrying fluids and electrical power to a tool inside the pipeline, the fluid and power supplies may be located on the floor of the reel, connected to an operator station by an electrical cable which winds onto and off of the turret shaft and is kept taut by a spring-biased tensioning arm. A flexible fibreglass rod extends through the cable to prevent coiling or bunching up within the pipeline while permitting the cable to traverse bends and corners.
