    • The breaker device for removing the tops of columns comprises a support structure composed of a plurality identical chain elements reciprocally linked by link couplings to form a closed chain which can surround a column which is to be topped. Each chain element bears a jackhammer provided with a plurality of interchangeable breaker punches, of varying lengths. Each chain element exhibits a plurality of holes which are distanced from the link couplings and which are for linking the chain elements. Each hole is aligned with a corresponding hole of an adjacent chain element. A pin is used for blocking adjacent chain elements in predetermined positions. The invention is useful for breaking the stop of a reinforced-concrete column without damaging the reinforcement elements thereof. The device can be adapted to columns having different diameters.
    • 用于移除柱的顶部的断路器装置包括由多个相同的链条元件构成的支撑结构,所述多个相同的链条元件通过连杆联轴器往复地连接以形成围绕待顶部的柱的闭合链。 每个链条带有一个装有多个可变长度的可互换的断路器冲头的手提锤。 每个链条元件具有多个与链接联接器间隔开的孔,并且用于链接链条元件。 每个孔与相邻链条元件的相应孔对齐。 销用于在预定位置阻挡相邻的链条元件。 本发明对于破坏钢筋混凝土柱的停止而不损害其增强元件是有用的。 该装置可以适应于具有不同直径的柱。

    • A modem utilizing a DAA having line side circuitry including a telephone network interface and system side circuitry including a host system interface, the line side circuitry and the system side circuitry being separated by a high voltage isolation barrier. A CODEC is provided in the line side circuitry, such that encoded information generated by the CODEC, as well as information for decoding by the CODEC, are communicated across the high voltage isolation barrier. These communications are accomplished in a digital manner. In an alternate embodiment of the invention, the line side circuitry of the modem further includes programmable detection and measurement circuitry that is programmable to measure electrical characteristics (e.g., tip/ring voltage and loop current) of the telephone line interface connection and is capable of corresponding adjustments to enable compliance with applicable regulations. The system is software programmable via control signals sent across the high voltage isolation barrier to establish electrical parameters corresponding to a specific country where the equipment may be used.
