    摘要： This invention relates to a continuous process for production of poly(trimethylene terephthalate), wherein gaseous 1,3-propanediol by-product resulting from the process is condensed in a condenser, the total amount of any trimethylene terephthalate cyclic dimer and poly(trimethylene terephthalate) in the condensed by-product 1,3-propanediol is adjusted, and a portion of the condensed by-product is recycled to the condenser while another portion is recycled back into the process.

    摘要： A golf green reading device has a lens with a reference line that is illuminated when the reference line is in a horizontal or vertical orientation. The reference line is illuminated by an electrical circuit secured within a housing having a power source, a light source, and a level switch. The user holds the device in a horizontal or vertical orientation to read the slope of a golf green relative to the reference line and determine the correct line to putt the golf ball.

    摘要： A method and an apparatus for automatically detecting the intactness of ground electrodes in the bath of an induction furnace are described. According to the method a low DC or AC current is applied to an additional insulated electrode extending through the furnace bottom and being in connection with the melt. After melting of the charge this current is measured and compared with a reference value. If the magnitude of the current drops below the reference value an alarm signal is generated. Furthermore, methods and devices for localizing a ground fault are described. By this, the security of the operation of an induction furnace is improved.

    摘要翻译： 描述了一种用于自动检测感应炉浴中接地电极的完整性的方法和装置。 根据该方法，将低直流或交流电流施加到延伸穿过炉底并与熔体相连的附加绝缘电极。 在电荷熔化后，测量该电流并与参考值进行比较。 如果电流的大小下降到参考值以下，则产生报警信号。 此外，描述了用于定位接地故障的方法和装置。 由此，提高了感应炉的操作的安全性。
