Title: Drug targeting system, method of its preparation and its use
Inventor: SCHROEDER ULRIKE
IPC: A61K51/12
Filed: 1997-06-13
Abstract: A composition and method of fabrication are presented with which nanoparticles may be used as a tool to deliver drugs to a specific target within or on a mammalian body. Specifically, by using stabilizers other than Dextran 70.000 during the polymerization process, according to the present invention, surfactants, which were deemed necessary coating material in the prior art, are no longer required. This is a significant simplification of the fabrication procedure. Many substances are useful as stabilizers, but the preferred stabilizers comprise Dextran 12.000 or polysorbate 85. In the present invention a drug is either incorporated into or adsorbed onto the stabilized nanoparticles. This drug/nanoparticle complex is then administered to the organism on any route such as by oral application, injection or inhalation, whereupon the drug exerts its effect at the desired site of pharmacological action. In a novel medical treatment process, the drug/nanoparticle complex may be administered preferably either by intravenous injection or by oral application. The resulting drug action, which does not occur or which occurs only to an insufficient extent when the drug is administered alone, shows that when linked to said nanoparticles drugs can reach a specific target within or on the mammalian body. The usefulness of the present invention as a universal approach to deliver any drug or diagnostic agent to a specific target within or on the mammalian body was demonstrated by experiments showing an unexpected transfer of the drug across the blood brain barrier.

Patent CA-2299790-A1 (CA)
Title: Method and apparatus for stimulating heavy oil production
Inventor: NENNIGER JOHN
IPC: E21B43/24
Filed: 2000-02-23
Abstract: A method of enhanced oil recovery having a number of steps. One step is to establish a flow path between an injection well and a production well. Then a solvent is heated, under pressure, until the condensation temperature of the solvent vapour is above the naturally occurring formation temperature. Then, the solvent is injected, under pressure, into the formation where it is permitted to condense. Then, the latent heat of condensation, together with warm solvent reduce the viscosity of the insitu hydrocarbon, while precipitating out asphaltenes. The reduced viscosity solvent/heavy oil blend is then recovered.

Par conséquent, les films fabriqués à partir des copolymères de la présente invention peuvent présenter des caractéristiques qui en font des copolymères adaptés à la fabrication de sacs à ordures ménagères, biodégradables, ainsi qu'à d'autres applications.
Patent CA-2301748-A1 (CA)
Inventor: FERRIS GAVIN ROBERT
IPC: H03J3/08
Filed: 1998-08-27
Abstract: In a first aspect the invention provides an apparatus for processing radio signals for connection to a personal computing device (PCD), in which a stream of digitised intermediate frequency (IF) data is maintained in at least one direction. In the inbound direction, information is received (104) as radio frequency (RF) signals by the device, down-converted (105) to IF and then digitised (107) and fed into the PCD (109) under control of an interface management unit (IMU 108). Software modules in the PCD then provide whatever demodulation processing is required for the transmission scheme in use. The invention further provides a transmitter apparatus. In the outbound direction, an IF signal is digitally synthesised by software on the PCD (109), according to an appropriate modulation scheme, and the resulting signal is passed to the device via the IMU, where it is used to generate (110) a corresponding analogue waveform. This waveform is then up-converted (112) to RF at the appropriate frequency and transmitted. As the PCD software is able to send commands to the device to set the centre frequency and bandwidth of RF to be accepted and transmitted, the device (together with appropriate software on the PCD) provides the basis for a generic, low-cost radio-frequency communications system. The invention may further provide a transceiver apparatus having both inbound and outbound channels.
Patent CA-2303046-A1 (CA)
Inventor: PRIOR ADALBERT
IPC: B01J39/26
Filed: 1998-08-28
Abstract: The invention relates to a method for reprocessing materials containing precious metals especially from metallurgic primary concentrates in which the materials are subjected to an increased temperature in the sequence of an oxidized treatment, a reducing treatment and a chlorination by the application of gaseous treatment media. Gold and the platinum group metals remain as residual matter with the characteristic that the residual matter is subjected to oxidized acid leaching. The gold portion is chromatographically separated first from the liquid phase and the remaining liquid is then chromatographically fractionated into the individual platinum group metals, whereby the fractionation is carried out by means of relative movement between a particle bed in the form of a cylinder jacket and at least one output position for the liquid.

Patent CA-2309109-A1 (CA)
Inventor: BLESZYNSKI STANISLAW
IPC: G01S7/35
Filed: 2000-05-23
Abstract: A signal processing method is presented for FM-CW radar where coherency in time of the mixer output signal is restored between the frequency sweep intervals, by the cancellation of the phase error (shift) between consecutive intervals. The restoration of coherency allows much higher resolution of the frequency spectra to be achieved, thus -improving the spatial resolution of the radar and reducing the dead zone. At the same time, the signal processing method allows for automatic correction of the frequency sweep function.
Patent CA-2316906-A1 (CA)
Inventor: SALLBERG KRISTER
IPC: H04W88/16
Filed: 1998-12-22
Abstract: A telecommunications system and method is disclosed for providing interoperability between a cellular system's direct access to the Internet and the telephony service provided by the Public Switched Telephone Network (PSTN), in order to allow a mobile subscriber to receive calls from the PSTN while engaged in data communication, for example, over the Internet. When a Mobile Station (MS) has an active connection to a server or router running Internet Protocol, an incoming PSTN call can be forwarded to a voice gateway within the serving Mobile Switching Center/Visitor Location Register (MSC/VLR), which transforms the call to an Internet phone call. During the direct access connection to the Internet, the MS can signal specific information, using, e.g., a prefix, to activate the call forwarding to voice gateway feature.

Title: Outboard motor
Inventor: MURATA HIROYUKI
IPC: B63H20/24
Filed: 2001-01-24
Abstract: An outboard motor includes a first case and a second case disposed below the first case. The first case houses therein an oil pan and an upper part of a drive shaft. Within the oil pan, engine oil is held. The second case has its upper edge portion coupled to a lower edge portion of the first case. The second case has a vertical wall disposed therewithin. The vertical wall separates a space within the second case into a cavity and part of an exhaust passage through which exhaust gas passes. The cavity is formed below the oil pan. This arrangement prevents the oil pan from being affected by heat of the exhaust gas. Thus, it becomes possible to prevent the engine oil held within the oil from increasing in temperature.
