Patent CA-2371149-A1 (CA)
Title: Communications controller for providing multiple access using a single telephone line
Inventor: GATESMAN KEVIN
IPC: H04L12/02
Filed: 2000-04-20
Abstract: Instead of having to subscribe to multiple telephone lines for multiple devices that a user has, a module (2) of the present invention can connect each of the user's devices to an outside communications network using the same telephone line. Such multiple inside connections to the outside communication network using the same telephone line is achieved by provisioning within the invention module the appropriate telephone and computer interface units for the user's telephones (4 and 6) and computers (14), and an appropriate network interface unit (16) for connection to the telephone line that connects the invention module to the external communications network. The module of the instant invention is further provisioned with an IP routing submodule that communicatively connects the various interface units together by managing the addressing of the data that traverses between the outside network and the devices of the user, by routing the appropriate data packets to the appropriate devices by means of pseudo internal IP addresses assigned to the various devices of the user. Other components within the module convert those data packets that are a part of a voice signal into the appropriate analog signal for output to the telephone of the user. Conversely, such components convert any analog input from the user into a corresponding digital signal that is packetized and output to the external communications network.
Patent CA-2372928-A1 (CA)
Title: Cast on-board injection nozzle with adjustable flow area
Inventor: SCHRAENEN YVAN
IPC: F16J15/447
Filed: 2000-05-18
Abstract: A Tangential On-Board Injection (TOBI) nozzle or a Radial On-Board Injection (ROBI) nozzle with adjustable flow area in a gas turbine engine for directing a cooling air flow into a rotor assembly of the turbine is disclosed. The nozzle is a cast structure including a plurality of tangentially cooling air passages, some of them cast-closed. After a flow test one or more of the cast-closed passages may be selectively machined open. Therefore, the structure is easily fabricated using a casting process with low manufacturing costs while the optimun cooling air flow is achieved by adjusting the total flow area of the nozzle before it is installed to the gas turbine engine. Furthermore, the nozzle is supported in a cantilevered manner to avoid the thermal stress. The adjustable flow area also enables the nozzle to be used in different types of engines.

Title: Scouring fleece
Inventor: LUTZMANN VANESSA
IPC: A47L17/08
Filed: 2002-06-26
Abstract: Scouring fleece including a flat structure of interconnected coarse fibres which form a three-dimensional network, whereby a continuous or discontinuous layer of resin or the like is adhered to the fibres, which layer includes an amount of abrasive granules and in addition thereto an amount of reflective bodies. The reflective bodies are thereby attached to the surface of the layer by being incorporated into the network through a spread-on application process. By incorporating reflective bodies into the scouring fleece, it becomes visible to the user of the scouring fleece whether and to which degree the scouring fleece is still effective. The reflective bodies are used up to the same degree as the abrasive granules during the use of the scouring fleece. When the scouring fleece has no more visible reflectors, its effectiveness based on the abrasive granules is used up.

Title: A method for measuring a marker indicative of the exposure of a patient to nicotine; a kit for measuring such a marker
Inventor: CHANGEUX JEAN PIERRE
IPC: A61K51/04
Filed: 2002-09-20
Abstract: The present invention demonstrates that epibatidine binds to nicotinic receptors on leukocytes. Epibatidine is a sensitive detector of increases in the number of nicotinic receptors expressed by a cell. Epibatidine binds to the leukocytes of smokers, but does not bind to the leukocytes of non-smokers.  Both in vivo and ex vivo nicotine exposure induces epibatidine receptor expression.  Epibatidine binding to leukocytes reflects epibatidine binding in the central nervous system, which in turn reflects nicotine-induced effects on the central nervous system. Epibatidine binding assays in peripheral blood leukocytes can be used to evaluate an individual's exposure to, and dependence on, nicotine.

IPC: B01D35/30
Filed: 2003-02-04
Abstract: The present invention is directed to a reverse osmosis membrane housing. The housing has a pressurizable cylindrical central pipe having a membrane opening end and an integral bottom end, an o-ring and a cap. The integral bottom end has at least a purified fluid outlet and somewhere on the cylindrical central pipe is a waste outlet. The waste outlet and the purified fluid outlet extend away from the pressurizable cylindrical central pipe. A ferrule extends from the membrane opening, and has a first alignment device to secure the o-ring in a desired position on the ferrule. The cap has a distal end and a proximal end. The proximal end has second alignment device to secure the o-ring in a desired position on the cap, while the distal end has an inlet port so a fluid can flow through the inlet port. Once the fluid is within the housing it can take two paths. The first path is into a reverse osmosis membrane positioned in the pressurizable cylindrical central pipe and to the purified fluid outlet. The other path is used if the fluid cannot penetrate into the reverse osmosis membrane positioned into the pressurizable cylindrical central pipe, thereby the fluid goes through the waste outlet.
