    • Control system and apparatus for controlling current input to an electrical resistance element such as a seal wire (2). The system and apparatus of the present invention is a closed loop feedback modification to conventional systems, and takes advantage of the inherent expansion of the seal wire (2) as it is heated. The feedback mechanism monitors the length of the sealing wire, and adjusts the current applied to the wire, responsive to that monitored length. One end of an electric impulse element such as a seal wire (2) is fixed to the underside of a top jaw (20) with a wire tension block. The opposite moving or floating end of seal wire (2) is coupled to a seal wire pivot member (1) at wire terminal (10). A pivot member (1) is pivotally mounted on the top jaw (20) at pivot point (9) so that it moves in response to expansion and contration of the seal wire (2), depending upon the seal wire temperature. A detector actuator (3) in mounted to the seal wire pivot plate or block (1), and extends beyond the pivot member (1) towards detector (5).
    • 用于控制电流输入到诸如密封线(2)之类的电阻元件的控制系统和装置。 本发明的系统和装置是对常规系统的闭环反馈修改,并且利用密封线(2)在被加热时的固有膨胀。 反馈机构监控密封线的长度,并响应于该监视的长度调节施加到电线的电流。 诸如密封线(2)的电动冲击元件的一端通过电线张力块固定到顶部钳口(20)的下侧。 密封线(2)的相对的移动或浮动端在线端子(10)处连接到密封线枢转构件(1)。 枢转构件(1)在枢转点(9)处枢转地安装在顶部夹爪(20)上,使得其响应于密封线(2)的膨胀和遏制而移动,这取决于密封线温度。 检测器致动器(3),其安装到密封线枢转板或块(1),并且朝向检测器(5)延伸超过枢转构件(1)。
