    摘要: The present invention relates to a process for the preparation of carbonic acid esters of monoalcohols or polyalcohols, which is characterized in that ureas are reacted with monoalcohols or with polyalcohols in the molar ratio of at least 1:2, in the presence of a catalyst, at reaction temperatures between 120.degree. C. and 270.degree. C.Accordingly, the present invention also relates to a process for the preparation of oligocarbonates and polycarbonates, which is characterized in that ureas are reacted with primary dialcohols in the molar ratio of about 1.5:1 to about 1:1.5, together with monoalcohols, in the presence of catalysts at reaction temperatures between 120.degree. C. and 270.degree. C.

    摘要: A system for sensing the position in space of the outer end of an articulated fluid loading arm while it is connected to a marine tanker or other transport vessel, and sounding an alarm if the arm's operating envelope is exceeded. The sensing system includes means for determining various angles representative of the orientation of the booms or limbs of the arm, and means for deriving from these angles an indication of the spatial location of the arm's outer end.
