This invention relates to a novel integrated method for economically processing vacuum residue from heavy crude oils. A V-spring assembly converts the movement of a power drive assembly in a back-and-forth movement. The side rails each include a side rail notch. The inverted and first delayed digital signal is inverted and second delayed by a second matching inverter and applied as one input to a second interpolator. A determining component determines whether or not the elapse of time measured by the measuring component reaches a preset value. In such apparatus, the hydraulic oil is flame resistant hydraulic oil which is hardly deteriorated by direct heating, and the flame resistant hydraulic oil is heated by a heater disposed in the oil tank.
