Patent CA-2410836-A1 (CA)
Title: Multistage pressure condenser
Inventor: INOUE KOICHI
IPC: F28B9/08
Filed: 2002-11-01
Abstract: Low-pressure-side condensate is subjected to convection heating while dripping in high-pressure-side steam, and to surface turbulent heat transfer due to a circulating flow caused by downflow condensate falling after overflowing. Thus, the temperature of the low-pressure-side condensate can be raised efficiently with satisfactory heat transfer. A bypass connecting pipe enables high-pressure-side condensate to bypass condensate of a reheat chamber and merge with the condensate while keeping a high temperature. Thus, heating of the low-pressure-side condensate is performed sufficiently, with a space for falling being minimized for compactness. Also, condensate in a high amount of heat exchange is fed toward a condensate pump. Hence, a multistage pressure condenser permitting compactness and increased efficiency of a power plant can be constructed.

Inventor: BATCHELOR MELISSA M
IPC: A61L31/16
Filed: 2002-01-16
Abstract: Biocompatible materials that have the ability to release nitric oxide (NO) in situ at the surface-blood interface when in contact with blood. The materials which may be polymers (e.g., polyurethane, poly(vinyl chloride), silicone rubbers), metals, such as stainless steel, carbon, and the like are provided with biocatalysts or biomimetic catalysts on their surface that have nitrite, nitrate and/or nitrosothiol-reducing capability that. Illustratively, the catalysts are adsorbed or immobilized at the surface of the material. The catalysts can act on endogenous nitrite/nitrate or nitrosothiols within the blood creating a local increase in the NO levels at the surface of the material. An illustrative enzymatic biocatalyst is mammalian xanthine oxidase.  In another illustrative embodiment, a biomimetic catalyst is a copper (Cu(II)-ligands complex, e.g., dibenzo[e,k]-2,3,8,9-tetraphenyl-1,4,7,10-tetraaza-cyclododeca-1,3,7,9-tetraene. In some cases, lipophilic salts of nitrite/nitrate (e.g., tridodecylmethylammonium nitrite (TDMA+NO2-/NO3-)) or certain salts of nitrosothiols can be doped within a polymer material, or an underlying polymeric film, to create a reservoir of nitrite or nitrosothiol that continuously leaks into the immobilized catalytic layer. Adequate levels of endogenous reducing equivalents are present within blood to provide catalytically-generated surface levels of NO that are above the threshold reportedly required to prevent platelet adhesion or activation.

Title: Lingual bracket
Inventor: HEISER WOLFGANG
IPC: A61C7/14
Filed: 2002-02-14
Abstract: The invention relates to a lingual bracket for orthodontic treatment in the incisor and canine region. The bracket has a slot that is aligned in parallel with the bracket base plate, said slot being aligned in such a way that the slot opening points towards the occlusal plane. The depth of the slot is preferably smaller than its width. Said slot acts as an organ for securing an aligning wire, being preferably covered by a closing spring, which is held in a stable manner on the bracket structure in the opening and closing positions. An aligning wire that lies in the slot is pressed against the base of said slot by the closing spring and also has a direct action on at least one lateral slot wall, generating the forces required on the bracket for correcting the tooth. The use of securing catches for the closing spring is no longer necessary, thus reducing the height of the bracket.
