Patent ID: 7595445

Claim:
A transposition device for changing a position of at least one bar of a canalization with respect to another bar of the canalization, such bars running parallel to each other in the canalization, the transposition device comprising: a plurality of bars of a canalization, the plurality of bars running parallel to each other in the canalization, each of said bars having an input portion at an input of the transposition device and an output portion at an output of the transposition device; a first bar of the plurality of bars having an input end terminating the input portion and an output end terminating the output portion; a conducting bridge mechanically connecting the input portion of the first bar with the output portion of the first bar, the input and output portions being physically separated from one another within the transposition device, the conducting bridge traversing a second bar, thereby changing a position of the first bar with respect to said second bar, wherein the input portion of the first bar comprises a first bend toward an outer edge of the transposition device and a second bend back toward a center of the transposition device, such that a first portion of the first bar adjacent to the first bend and extending to an input of the transposition device from the canalization and the first bend defines a first input section, a second portion of the first bar between the first bend and the second bend defines a second input section, and a third portion of the first bar between the second bend and the input end of the first bar defines an input end section, and the output portion of the first bar comprises a third bend toward an outer edge of the transposition device and a fourth bend back toward a center of the transposition device, such that a fourth portion of the first bar adjacent the third bend and extending to an output of the transposition device defines a first output section, a fifth portion of the first bar between the third bend and the fourth bend defines a second output section, and a six portion of the first bar between the fourth bend and the output end defines an output end section, wherein the first input section, input end section, first output section, and output end section are parallel to one another.
