Abstract: A portable, motor operated machine is shown having a box-like housing or work surface that supports an electric motor on one side thereof. A removable elongated shaft or spit is connected into a receiving socket of the motor so as to be turned thereby. The shaft extends transversely across the housing or work surface, and there is a quick-releasable shaft-bearing mounted on the opposite side of the housing for supporting the other end of the shaft. A sheet of newspaper is adapted to be attached to the shaft for winding the paper onto the shaft as the motor slowly turns the shaft. A first pressure plate is hingedly supported near the rear edge of the housing, and it is urged into engagement with the paper roll. A second pressure plate is hingedly supported from the rear edge of the housing and it carries the first pressure plate means thereon. An elongated guide roller is positioned adjacent the front of the machine below the shaft for applying tension to the paper.

Abstract: A mobile unit for the treatment of BS to recover the saleable oil therefrom, and to clean the oil storage tank. The cleaning and treatment system is mounted on a truck or the like, so it can be taken to individual storage tanks from which the BS and water is to be removed from the bottom thereof and the storage tank cleaned. The components of the system are a BS treatment tank, a heating unit with a burner and coils, with the necessary pipes, valves and pumps to withdraw the BS from the bottom of the oil storage tank, heat and treat the BS until the water and marketable oil are separated and the saleable oil returned to the storage tank. The water and residue are discharged to a suitable place of disposal.
