Title of Invention

IMPROVED VENTILATABLE ELECTRICALLY AND THERMALLY INSULATED FLEXIBLE DUCTING.

Abstract

Ventilatable flexible carrier ducting compriSing plurality of staggered ducting link units 4 coupled to each other by means of pivotally attached intermediate clamping bands 5 having vent holes arid clamping band at each end of said articulated ducting being fitted with an end coupling 9 having o. grooved ring 9 A on its one side and the web on ofcher side thereof carrying a pair of spaced holes for fixing said flexible ducting to respective fixed and moving connection 0f a device by means of screws and wherein each link unit 4 beina formed by coupling two frame 10 A-10 B stggered cu^d.linked by a intexconnectable pivotally attached clamping band 5 linking two braCket sections 5 A- 5 3 and wherein rib 6 F formed on the lower half section 6 B of said coupling band is carrying spaced Vent h0ies $ J for ventilating said flexible ducting arid wherein said rjyets forming pivot pins comprising a combination of an expandable hollow rivet 8 and a detachably fixable locking plug 7 and Wherein said ducting is ventilated through said vent holes by^ Pumping action caused lUll^l 'to-and-fro7 travel of said duct^g between fixed moving consumer connection of a device.
