  • Gamma-irradiation treatment apparatus
    Patent number: 4048509
    Abstract: The radiation source mounting frame is raised and lowered by means of an elevator comprised of a block and tackle and a servo-motor having an output connected to a movable pulley block of the block and tackle. The elevator allows the mounting frame to be lowered at a rapid rate when necessary. The supply line for the pressure medium is also disposed near the end of the piston stroke so that the line can be throttled before the piston reaches the end of its stroke. This allows the final descent of the mounting frame to be retarded.
