Patent CA-2189379-A1 (CA)
Title: Pump impeller with adjustable blades
Inventor: RAMSAY THOMAS W
IPC: F04D15/00
Filed: 1996-11-01
Abstract: The pump has an impeller with a retractable component, which, when moved, exposes more or less of the impeller blades, thereby varying the pumping action.The pump has rotor and stator sleeves with complementary tapered surfaces, in which a groove conveys barrier liquid towards the impeller.  A piston and cylinder receives the liquid thus conveyed.  The pressure of the liquid is controlled by a pressure regulator.  A spring biasses the moveable impeller blades one way, and the piston and cylinder oppose that force, whereby the exposure of the impeller blades can be controlled.

Patent CA-2196826-A1 (CA)
Inventor: FLANDERS BRUCE
IPC: E21B29/00
Filed: 1997-02-05
Abstract: A downhole cutting tool for use in a wellbore, the cutting tool having a mandreland a cylindrical knife body slidably mounted coaxially on the mandrel.  The mandrel can be attached to or suspended from any type of workstring.  The upper ends of a plurality of knife blades are pivotably mounted at fixed points on the knife body.  The knife blades are suspended therefrom over a plurality of ramps formed on the exterior of the mandrel.  A pressure chamber is formed between the knife body and the mandrel.  Fluid from the work string can be directed through the mandrel to the pressure chamber, to drive the knife body downwardly relative to the mandrel, causing the lower ends of the knife blades to contact the ramps on the mandrel and kick or pivot outwardly to cause the lower tip of the blade to contact the downhole material to be cut. As the mandrel is rotated, the knife blades rotate with it and cut into the material.  The point at which the lower end of the blade contacts the ramp is a fulcrum point which is closer to the lower tip of the blade than to the upper end of the blade.  This creates a mechanical advantage causing the lower tip of the blade to be more forcefully urged into the material to be cut.

Patent CA-2214766-A1 (CA)
Inventor: DOYLE THOMAS F
IPC: B60R16/02
Filed: 1996-03-01
Abstract: A system for monitoring and the adjustment of control unit parameter settings of vehicle electronic control units (44, 45).   The monitoring system may be implemented in a vehicle (12, 14) in which are incorporated one or more electronic control units (44, 45) for regulating one or more operational parameters of the vehicle (12, 14) in accordance with corresponding control unit parameter settings. In an exemplary implementation the vehicle (12, 14) is equipped with a mobile communications terminal, MCT (38), which receives from a base station (18) a list of operational parameters to be monitored. Each of the electronic control units (44, 45), as well as a memory unit (62), are connected to an internal data link (40) of the vehicle. When a parameter value within the memory unit (62) corresponding to a given electronic control unit (44, 45) is changed, a message is provided to the base station (18) specifying the value currently registered by the particular electronic control unit (44, 45). The currently registered value is then compared to an expected parameter value, and an error message is generated if disagreement exists therebetween. The system also allows vehicle electronic control unit parameter settings to be adjusted from a remote location such as a base station (18).

Patent CA-2216913-A1 (CA)
Title: Method and apparatus for determining bone density
Inventor: DIMAROGONAS ANDREW D
IPC: G01N29/00
Filed: 1996-03-29
Abstract: The density of a discrete piece of hard tissue such as a bone in a patient may be determined by either of two methods. In a first method, an impulse of energy is introduced into the tissue, and the resulting vibration in the hard tissue is sensed and analyzed to compute the modal damping factor of the tissue, the modal damping factor being directly related to the density of the tissue. In a second method, a continuous energy input is introduced into the hard tissue. The resulting vibration in the tissue is measured with a mechano-electrical vibration transducer (26) and a modal damping factor is calculated. The electro-mechanical vibration transducer (26) of the preferred embodiment measures the pressure with which the transducer (26) is pressed against the patient's flesh and only produces the continuous energy input when a predetermined pressure is achieved which is sufficient to prevent any significant vibration of the flesh surrounding the bone.

Patent CA-2221912-A1 (CA)
Title: Photosensitizers with improved biodistribution and light-absorbing properties
Inventor: DOLPHIN DAVID
IPC: C07D471/22
Filed: 1997-11-21
Abstract: The objective of this work was to develop methods for preparing novel photosensitizer drugs with a) improved selective accumulation in diseased tissue and b) increased wavelengths of activation. The approach taken to enhance selectivity involved exploiting the upregulation of steroid receptors within tumorous cells. Porphyrinic photosensitizers were conjugated to a variety of steroids, ranging from cholesterol to the estrogens and androgens. A number of linking methods were employed: cholesterol was attached at the 3-position via a carbamate group or a diene tether. However, these linkages were non-ideal, as the products lacked the desired stability or existed as geometric isomers, and so improved techniques were sought. This lead to the development of a palladium-catalyzed cross-coupling technique to link 10-iodo-5,15-diphenylporphyrin with hormonal steroids ethynyl-substituted at the 17-position. Using this method, a series of steroid-porphyrin conjugates was prepared. In an extension of this work, selective couplings were performed on 5-bromo-15-iodo-10,20-diphenyl-porphyrin, in which the iodo-group alone reacted under mild conditions. A second coupling under more rigorous conditions resulted in reaction at the bromo-substituent, creating a bifunctionalized porphyrin product. This provides an alternative method to the synthesis of asymmetrically-substituted porphyrins. Efforts at increasing the absorption wavelength of the photosensitizer lead to the design and synthesis of new chlorin systems based on octaethylporphyrin and possessing exocyclic nitrogen-containing rings. Through these studies three new types of chlorin chromophore were prepared, each absorbing above 670 nm. In addition, an unusual dimeric chlorin was unexpectedly formed, for which an X-ray crystal structure was determined. Finally, attempts were made to prepare analogous chlorins based on other porphyrin systems. As initial efforts at synthesizing a tailor-made base porphyrin system were unsuccessful, 5,15-diphenylporphyrin was chosen as the starting material. Studies aimed at iii improving the synthesis of this compound were partially successful. A series of meso-substituted diphenylporphyrin derivatives was prepared in a similar manner to that used for the octaethylporphyrin analogues. However, these derivatives did not give rise to chlorin products.
