Abstract: The integrated solar wall with thermosyphon system is an energy saving concept with an advantage since all the energy captured by the solar wall is used all year round. When the underground parking requires heat, energy is delivered to the underground parking or make-up air. If no heat is required, then the air flow is directed to preheat the domestic hot water line. Heating the domestic hot water line is achieved by thermosyphon. The s~ant/fin pipe is heated by the air flow and the water in the 2" pipe is heated by thermosyphon. This system has its advantages: there are no moving parts in the process of preheating the domestic hot water and there is no use of propylene glycol because all pipes are indoor and there is no chance for the water to freeze up. The fan is off and both dampers are closed when solar panel temperature is below 50~F.

Patent CA-2330302-A1 (CA)
Inventor: VERINGA HUBERTUS JOHANNES
IPC: C10J3/54
Filed: 1999-04-29
Abstract: The invention relates to a method and an apparatus for forming synthesis gas from biomass and/or residues. In a biomass gasifier and/or residues gasifier, synthesis gas is formed, part of which is combusted, the combustion heat being transferred to a reformer. In the reformer, a fossil hydrocarbon is converted into synthesis gas which is mixed with the synthesis gas formed in the gasifier. The method and apparatus according to the invention afford a high cold-gas yield, and the production of CO2 per kilogram of synthesis gas (H2 and CO) produced is low. Owing to the low degree fo integration of the gasifier and the reformer, the H2/CO ratio can be adjusted over a wide range. The apparatus according to the invention is relatively simple and reliable, given that the only connection between the reformer and the outlet of the gasifier is via a branch line. Coupling the gasifier and the reformer according to the invention permits a gradual transition from the use of fossil fuel to a more sustainable hydrocarbon source. Moreover, the quality of the synthesis gas formed in the biomass gasifier can be improved by mixing with the synthesis gas from the reformer, and control of the feed streams allows a variable syngas composition (H2/CO ratio) to be achieved.

Title: Preformed wire guide
Inventor: MORRIS EDWARD J
IPC: A61B5/00
Filed: 1999-08-19
Abstract: A preformed anchoring wire guide (10) for medical procedures such as renal angioplasty. The wire guide (10) includes a preformed bend (14) having an angle (15) with respect to the longitudinal axis (28) that corresponds with the takeoff angle of the renal artery (23) relative to the aorta (33). This preformed bend (14) allows easier access to the ostium (22) of the renal artery (23) and allows the distal portion (27) of the wire guide to anchor within the artery (23), thereby improving trackability of a balloon angioplasty catheter (21), reducing the need for a guiding catheter, and reducing the likelihood of vessel damage or thrombus shear due to forces that are normally exerted against the wall of the vessel (33) by a standard wire guide. The wire guide is comprised of a lubricious polymer-coated (19) superelastic memory alloy mandril (11), such as a nickel-titanium alloy, having a tapered distal portion (20) over which a flexible tip portion (12) comprising spring coil wire is attached to provide radiopacity and safety to the vasculature. The distal portion (27) of the wire guide is further made atraumatic by the addition of a hook-shaped or "J" tip (29).  Additionally, the nickel-titanium alloy mandril is cold-worked in its austenitic by overstressing the wire in a fixture, thereby shifting at least part of the crystalline structure to martensite within the region of the preformed bend (14). The cold-worked nitinol wire guide has improved resistance to dislodgement and deformation by an advancing catheter while still retaining its desirable superelastic properties.

Patent CA-2351243-A1 (CA)
Title: Color printer calibration
Inventor: PIATT MICHAEL J
IPC: H04N1/60
Filed: 2001-06-20
Abstract: The present invention addresses the quantification of a printed tone scale for each individual color in a printing system, developing a linear tone scale derived in an independent color space and referenced from the shade of the unprinted substrate. The present invention determines the threshold for excessive ink coverage of a printing system on a specified substrate. This determination is based on a subjective evaluation of acceptable thresholds for bleed, cockle, show through, and image density. The method works in conjunction with a predefined test pattern printed on the specified substrate at fixed printing parameters, such as speed, dryer temperature, and web tension. This invention also includes an ability to limit the ink of each independent color in the system as a fraction of the total upper ink limit. Furthermore, this invention allows calibration of the tone scale of each color in the system using the color of the paper as a reference point. In addition, this invention facilitates the generation of separate sets of tone scale transformations for both graphics and text for each color in the system.
