Patent CA-2336017-A1 (CA)
Title: Electrochemical treatment of water and aqueous salt solutions
Inventor: POPOV ALEXEY YUREVICH
IPC: C02F1/461
Filed: 1999-06-30
Abstract: A relatively concentrated and a relatively dilute aqueous salt solution are respectively passed through the anode and cathode chambers of a flow-through  electrochemical cell having a porous membrane separating the two chambers. T he fluid pressure in the cathode chamber is maintained at less than atmospheric  pressure and at less than the fluid pressure in the anode chamber while a potential difference is applied across the anode and cathode. In this way, dangerous build-up of gaseous electrolysis products in the chambers, especially the anode chamber, is avoided.

Title: Evacuated sensor device for detecting microorganisms in blood samples, and method therefor
Inventor: MARESCH MARTIN J
IPC: C12M1/34
Filed: 1999-07-12
Abstract: A device and method allow for collection of a blood specimen and for detecting the presence of microorganisms in the blood specimen. The device is a sensor plate under vacuum which provides an environment to culture microbial organism colonies from a blood sample and a means to facilitate microbial detection and quantification manually or with an instrument. The vacuum sensor plate has a microorganism immobilisation matrix layer and a sensor layer. Detected microbial colonies are immediately available for further testing. A kit is provided having a needle assembly for direct draw of blood from a patient onto the immobilisation layer within the vacuum sensor plate. The sensor plate provides an area for accepting a blood sample, a mechanism to immobilize the blood sample on an interior surface of the plate, nutrients to facilitate growth of microorganisms in the sample, and a sensor layer for allowing the detection and/or enumeration of microorganism colonies within the blood sample. The Figure is an illustration of sensor plate (1) which can be in the form of a flat, shallow container with at least one side being transparent or lucent.
Patent CA-2337753-A1 (CA)
Inventor: FUHRMAN BIANCA
IPC: A61K35/00
Filed: 1999-06-22
Abstract: La présente invention concerne de nouvelles compositions à base de gingembre destinées à traiter l'athérosclérose et les états apparentés. Cette composition renferme notamment, comme composants, des extraits de gingembre normalisés, ci-après dénommés "ROZ20", analysés in vivo afin de déterminer s'ils peuvent réduire les modifications athérogènes de la lipoprotéine de basse densité (LDL), et faire diminuer ou au moins sensiblement prévenir la progression de l'athérosclérose, cette étude ayant été conduite chez une souris carencée en alipoprotéine E (Eo). Après 10 semaines au cours desquelles cette souris a consommé 250 microgrammes par jour de ROZ20, la totalité de l'aorte de cette souris a été examinée afin de détecter toute lésion athéroscléreuse. On a ainsi découvert que la région moyenne des lésions de ladite souris traitée avec ROZ20 a diminué de 67 % par rapport à la région des lésions d'une souris traitée au placebo. Ces résultats montrent donc clairement que l'administration de ROZ20 à une souris Eo atteinte d'athérosclérose sur une période de 10 jours a un effet bénéfique considérable et permet de réduire sensiblement la taille et la progression des lésions athéroscléreuses.

Patent CA-2339609-A1 (CA)
Title: Fluid sterilization apparatus
Inventor: THORPE GEORGE W
IPC: C02F9/00
Filed: 2000-06-05
Abstract: Apparatus for treating water or other fluid with radiant energy from an ultraviolet lamp (90) includes a helical shaped input fluid flow guide or helical ramp (60) disposed at or near one end an elongated annular chamber around the lamp. The guide or ramp serves to impart input spiral flow momentum to the fluid upon entry to the chamber. A corresponding output fluid flow guide or helical ramp (70) may be disposed at or near the opposed end of the chamber to impart output spiral flow momentum to the fluid as it approaches discharge from the chamber. Spiral flow serves to extend the time that the fluid is exposed to ultraviolet light and thereby increases the probability that any microbiological contaminants present in the fluid will be killed. The use helical shaped guides or ramps better serves to establish such a flow in circumstances where the available fluid pressure is relatively low.

Title: Security systems for inhibiting theft of goods from retail stores
Inventor: MARTIN ALFRED HENRY
IPC: G06V30/224
Filed: 1999-10-28
Abstract: A checkout system for a retail store is disclosed which comprises a bar code reader (10) and an anti-theft tag deactivator (14). The bar code reader produces a signal upon the bar code on an article being read successfully by the reader. This signal is used to enable the deactivator for a predetermined period of time whereafter the deactivator is disabled until the next successful bar code read. This minimises the prospects of a cashier being able to deactivate the anti-theft tag on an article without having read the bar code on the article and hence entered the sale. The system can also include a microswitch for detecting closing and opening of the cash drawer. If the drawer is left open, but the bar codes on articles are read by the bar code reader, this can indicate the possibility of goods being fraudulently removed from the store.

Patent CA-2355663-A1 (CA)
Inventor: KALENIAN PAUL A
IPC: A23F3/18
Filed: 1999-10-05
Abstract: Typical current methods for producing large quantities of extracts from solid raw materials such as ground, roasted coffee are designed for exhaustive extraction. Such methods are not ideally suited to producing high quality coffee extracts that are rich in flavor and fragrance, and which maintain the varietal characteristics of the roasted coffee from which they are produced.  The current invention provides methods and apparatus for producing such high quality extracts. The invention provides methods that have sufficient flexibility and scalability to be used for a wide variety of applications, including for producing industrial-scale quantities of extracts for the food and beverage industry. The invention provides methods and apparatus that can produce highly concentrated, "gourmet quality" extracts for use a flavoring agents, beverage concentrates, and fragrances. The inventive extraction methods, in some embodiments, involve subjecting roasted coffee to a static pressure treatment with pressurized solvent and/or removing extract from the bed of roasted coffee with a non-solvent gas as a final extraction step. The inventive methods can reduce the extent of extraction of the roasted coffee and the level of bitter, off-flavor components present in the coffee extracts.  The extracts produced according to the invention can be advantageously used for applications where high quality coffee extracts, with a relatively high concentration of soluble coffee solids and a relatively high level of sweetness but without substantial amounts of bitter oils and acids, are desired.

Patent CA-2377872-A1 (CA)
Inventor: DELCEA LUCIAN BOGDAN
IPC: H05H1/34
Filed: 2000-07-11
Abstract: A plasmatron operating efficiently within a wider range of gas flows and capable of sustaining a stable arc voltage.  The plasmatron generates an electric arc at the tip of a cathode electrode and transfers the arc along an arc chamber and into the bore of an anode electrode located at the downstream end of the arc chamber. A  plurality of arc root attachment surfaces are defined on an inner surface of the anode by a plurality of ring members, causing the electric arc to attach with its root to the arc root attachment surfaces and therefore the axial movement of the arc root is confined substantially to the anode electrode. The arc voltage variations are limited and controlled substantially by the arc root movement between two adjacent arc root attachment surfaces. When used within a plasma-spraying torch, the plasma stream generated by the plasmatron has improved characteristics and induces improved plasma spray coatings.
