A flexible, electrically heatable hose having an elongated electrical conductor which extends in the helical shape in the hose direction is illustrated and described. The object of providing a flexible, electrically heatable hose in which uniform heating over the hose length is ensured even in the event of major deformation of the hose, is achieved by a hose which has an elongated electrical conductor which extends in a helical shape in the hose direction, wherein the electrical conductor is embedded in a braid. In this case, the braid has first and second strands, wherein the first strands extend in a helical shape in the hose direction in the same winding direction as the electrical conductor, and the second strands extend in a helical shape in the hose direction in the opposite winding direction to the electrical conductor. The pitch angle of the electrical conductor, which extends in a helical shape in the hose direction, of the first strands and of the second strands is in this case between 50&#xb0; and 80&#xb0;.

A method of dry cooling coke using a coke transporting bucket which has a removable cover with an exhaust pipe extending from the interior of the bucket to an exterior exhaust connection and a cooling shaft for the coke comprises directing red hot coke into the bucket, covering the bucket with the cover and transporting the coke to the cooling shaft and connecting the exhaust pipe to the exhaust system while the bucket is in the shaft and emptying the bucket into the cooling shaft. The coke transporting bucket comprises a container having a bottom discharge which is closable by a flap and a removable cover which seats around the rim of the container to seal it. An exhaust pipe is carried by the cover and it extends into the interior thereof for removing gases from within the bucket and delivering them to an exterior connection which is connectable to an exhaust line. One or two exhaust pipes may be provided on the cover and each includes cover flaps which are biased into a closed position but which open to connect to the exhaust system when the cover is positioned to engage the exhaust line. The cover advantageously includes longitudinal girders which extend outwardly from each side or end of the cover and provide a means for supporting the cover when the bucket is lowered beneath a support structure to free the cover from the bucket.

Method for dry cooling coke

A method for the dry cooling of coke comprises transferring the coke from the coke oven to a special bucket which is moved over a charging hole of a cooling pit. The space between the bucket and the charging hole is closed off and sealed against the atmosphere and a shutter which closes the top of the charging hole is moved upwardly and then transversely off the charging hole to open it as an intermediate charging guide piece is moved in position between the hole and the bucket for the transfer of the coke therebetween. The space between the bucket and the charging hole is sealed by a frame of a sluicing device in which the shutter and the intermediate charging hole guidepiece is movable. The device advantageously runs on wheels which are located outside the frame which seals the sapce between the charging bucket and the charging pit. The frame of the sluicing device advantageously includes a sealing element which engage into a recess seal combined around the charging hole.

A gas collecting hood for taking off emissions from coke being pushed out of coke oven chambers, travels along with a coke guide alongside the battery. The hood is connected through a gas collecting duct to a stationary exhausting system. The hood is supported at three points, through roller (15,16) at two points (A,B) on a rail (11) which is provided at the hood side remote from the coke guide (3), and pivotally at a point (C) on the coke guide (3).
