Abstract: A resection endoscope has a high frequency energized cutting electrode which can be moved longitudinally by a carrier. A switch for the high frequency current is mounted on the carrier so that when the carrier is actuated in the cutting direction the current is switched on and is otherwise switched off. Thus the switch actuation is coupled to the carrier actuation for simplifying the operation. A certain lost motion is advantageously provided for the switch actuation which enables the high frequency current to be selectively switched on or off even when the cutting electrode is stationary.

Abstract: The invention relates to an assembly of members for programming and controlling the process of a blanking or die cutting machine, which process, because of simply comprising shearing machine blows, is programmed and controlled by merely fixing before hand the amount of blows that the machine should give, and then controlling the given blows. The invention is characterized in that the assembly or unit comprises a filing cabinet intended to accomodate the blanks or die cuts to be used for the process, each file being provided with members responsive to the presence of said blanks or die cuts, so that as a blank or die cut is withdrawn or picked up, the relative programming members are activated as set on the control board.
