Abstract
817,567. Pipe-line cleaning devices having radio-active source. UNITED KINGDOM ATOMIC ENERGY AUTHORITY., Oct. 30, 1957, No. 33829/57. Addition to 781,775. Class 40(3). Apparatus for cleaning pipe lines, as claimed in the parent Specification, is provided with a mechanical motion translating mechanism for providing relative movement between the screening pot and the holder for the radio-active source. The source holder 2 is held by a spring 3 against a disc 28 carried by a rack 26 which is engaged by a large pinion 25 arranged between and fast with two smaller pinions 24 on an axle mounted in a sliding assembly 22 engaged by a polythene block 17 at the free end of the bellows 5. The smaller pinions 24 engage fixed racks 19 whereby movement of the assembly 22 upon compression of the bellows 5 rotates the pinions and transmits amplified movement to the rack 26 to move the holder out of the screening pot 9. The travel of the holder 2 can be controlled by altering the volume of air in the bellows 5 which can be effected by adding oil via a cap 6 to a tube 13 which contains the spring 3 and holder 2.
