    • Continuous processes for preparing polycarbonates having a weight average molecular weight MW, of 15,000 to 200,000 g/mol, the processes comprising reacting a dihydroxydiarylalkane and phosgene in the presence of a catalyst in a phase boundary process comprising: continuously dispersing in a disperser an organic phase comprising at least a portion of the phosgene and a solvent suitable for the polycarbonate and an aqueous phase comprising the dihydroxydiarylalkane, water and an alkali solution present in an amount of 1.5 to 2.5 moles per mole of the dihydroxydiarylalkane, to form a mixture; reacting the mixture in a first reactor with a residence time of less than 0.5 seconds; further reacting the mixture in a second reactor with addition of further alkali solution and, optionally, a chain terminator; and effecting further condensation in a third reactor with addition of further alkali solution and, optionally, a chain terminator, in the presence of the catalyst.

    • An acceleration and deceleration sensor includes a housing; first and second elongate cavities formed in the housing and extending parallel to one another; a reed switch disposed in the first cavity; a first elongate permanent magnet immovably secured in the second cavity; and a second elongate permanent magnet longitudinally slidably received in the second cavity and arranged end-to-end relative to the first magnet. The reed switch and the second magnet are arranged with respect to one another such that upon movement of the second magnet the magnetic field thereof actuates the reed switch. The sensor further has a lid cooperating with the first cavity and has a closed and an open position. In the closed position the lid covers the first cavity and is supported on the housing and in the open position the first cavity is exposed to environment external to the housing. The lid is arranged for movement from the closed position to the open position in a direction transverse to the length dimension of the elongate first cavity. There is further provided an adjustment screw closing an end of the second cavity.
    • 加速和减速传感器包括壳体; 第一和第二细长腔形成在壳体中并且彼此平行延伸; 设置在所述第一空腔中的簧片开关; 第一细长永久磁铁固定在第二腔中; 以及第二细长永久磁铁,其纵向可滑动地容纳在所述第二腔中并相对于所述第一磁体端对端地布置。 簧片开关和第二磁体相对于彼此布置,使得在第二磁体移动时,其磁场致动簧片开关。 传感器还具有与第一空腔配合并具有闭合和打开位置的盖子。 在关闭位置,盖子覆盖第一腔体并被支撑在壳体上,并且在打开位置,第一腔体暴露于壳体外部的环境。 该盖被布置成在垂直于细长的第一腔的长度尺寸的方向上从关闭位置移动到打开位置。 还设置有一个关闭第二腔的一端的调节螺钉。
