  • Patent number: 8500320
    Abstract: A gas mixer (10) for mixing a first gas stream with a second gas stream includes an impact labyrinth (24) in the first gas stream having structures (25), e.g., corrugated walls, forming a tortuous path through which the first gas stream must pass en route to a mixing point (20) in the gas mixer. The labyrinth fosters ignition of particles entrained in the first gas stream. Elongate, straight pipes (30) receive the first gas stream from the impact labyrinth (24) and carrying the first gas stream to the mixing point (20) the pipes (30) are positioned with a vessel (12) carrying the second gas stream. The pipes (30) have openings which are substantially aligned with the flow direction of the second gas stream at the mixing point (20) thereby introducing the first gas stream into the second gas stream in a low shear manner.

  • Patent number: 8445530
    Abstract: The present invention relates to compounds of the formula I, wherein A, Y, Z, R3 to R6, R20 to R22 and R50 have the meanings indicated in the claims, which are valuable pharmaceutical active compounds. Specifically, they are inhibitors of the endothelial differentiation gene receptor 2 (Edg-2, EDG2), which is activated by lysophosphatidic acid (LPA) and is also termed as LPA1 receptor, and are useful for the treatment of diseases such as atherosclerosis, myocardial infarction and heart failure, for example. The invention furthermore relates to processes for the preparation of the compounds of the formula I, their use and pharmaceutical compositions comprising them.

  • Publication number: 20120253001
    Abstract: Insulated glass units are sealed with polyurethane made using a natural oil-based polyol (NOBP). In one embodiment the NOBP is made using a monol-rich monomer containing high levels of mono-hydroxy functional fatty acid methyl esters. Insulated glass sealants based on these compounds provide enhanced resistance to UV and oxidative degradation as compared to conventional products while still providing the required barrier and mechanical properties.
