A switching chip for performing switching and other functions on packets transmitted through the switching chip. The system may further comprise a slide guide configured to engage with each of the arm of the lock head and the slide guide track and to translate along a length of the slide guide track. Thus, a coupler may affix to different valves or actuators provided the appropriate affixment holes are chosen. The first deflection device is displaceable for compensating the sliver length between first and second end positions, wherein signal transducers emit a signal when the first or second positions are reached. At least one hearth may include two spaced rows of air feed-tubes longitudinally embedded therein for delivering a combustion gas into the combustion chamber.
