    摘要: 1,4-Dihydro-6-methyl-4-(substituted phenyl)pyridine-3,5-dicarboxylic acid esters have an amino group at the 2-position and at least one nitrooxy group in at least one of the ester groups. These compounds have a variety of valuable activities, including antihypertensive and Ca.sup.++ -blocking activities, leading to their use for the treatment of circulatory and coronary disorders. They may be prepared by condensation of appropriate substituted acetic acid esters.

    摘要: A pulse combustion apparatus comprises (i) a single air supply section with a single air blower and (ii) a plurality of combustion sections each communicating with the air supply section. The air supply section includes passages communicating with both the blower and the respective combustion sections for admitting air from the blower into the respective combustion sections. The air admitting passages are physically separated from each other for separating air from the blower into streams which are not able to join together anywhere.
