摘要:
The present invention provides benzimidazoles of the general formula: ##STR1## wherein R.sub.1, X, A, and R.sub.2 are as defined in the specification. The present invention also provides processes for the preparation of these new benzimidazoles and pharmaceutical compositions containing them, as well as intermediates for the preparation thereof.The new benzimidazoles are useful to treat heart or circulatory diseases which respond to a lowering of blood pressure, a positive inotropic action and/or an improvement in microcirculation.
摘要:
A regulating device for the flue housing of a coke oven for alternately opening and closing channels of the flue housing including a rotatable shaft, frames mounted on the shaft, preferably, 90.degree. relative to each other, in alternating sequence along the shaft, peripheral seals about the frames for sealing a channel when the frame is disposed across it. The seals are arcuate in configuration and lie on a circle having its center at the center axis of the shaft. Rotation of the shaft selectively opens and closes alternate channels of the flue housing.
