A mechanism for securing multiple apparatus to a drain cleaning machine is described. The mechanism includes a bracket arranged on a frame of the drain cleaning machine. The bracket allows a drum and a feed mechanism to be removably secured to the frame. The bracket includes a base and pivotable latch. A drum bearing from the drum can be secured between the base and the latch when the latch is in a closed position. Mounting pins from the feed mechanism can be inserted into two bores in the bracket, and secured therein by plunger pins. One plunger pin is manually operated, to selectively lock the latch in the closed position, and to selectively secure one of the mounting pins in one of the bores. Another plunger pin is operated by pivoting of the latch, and functions to selectively secure the other mounting pin in the other bore.

An apparatus and related process for the internal cleaning of a pipeline that includes an interchangeable rotary cleaning head, a motor device coupled to the rotary head, a movement device configured to move the apparatus inside the pipeline, and a remote control system. The combined movement of the rotary head rotation and of the advancing motion of the apparatus inside the pipeline allows the disintegration of the deposits present internally of the pipeline by mechanical action.

A pipe pig is provided with linked wheels, and at least a central wheel of the linked wheels is pivotally linked to adjacent wheels through a spring loaded connection that biases the central wheel out of straight line alignment with the adjacent wheels. The pipe pig may be used to negotiate tight bends in a pipe and carry sensing electronics.

A process for multistage thermal treatment of rubber waste, in particular scrap tires, is proposed. The process comprises several steps of transferring a product granulate of rubber waste into three different sequencing heating zones of a reactor (10). In the heating zones (11a, 11b, 11c) the product granulate is heated at a first temperature between 100 to 200 C., preferably 150 to 180 C., then at a second temperature between 200 to 350 C. and at a third temperature between 300 to 600 C. The temperature is maintained until such time that no further oil is emitted within the respective heating zone. As a final step, the product granulate is removed from the reactor (10) and the desirable solid materials are separated.
