Fuels used may be derived from existing waste streams such as animal wastes and streams of discarded or unwanted animal byproducts generated at animal slaughterhouses. A method of processing organic waste products into fuel includes homogenizing the waste products. The waste products are heated and pressurized. Water is removed from the waste products. Selected constituent of the waste products are separated from the waste products into a waste stream. The waste stream is blended with a fuel to form a bio-fuel mixture.

Methods for providing drawing assistance to a user sketching an image include geometrically correcting adjusting user strokes to improve their placement and appearance. In particular, one or more guidance maps indicate where the user “should” draw lines. As a user draws a stroke, the stroke is geometrically corrected by moving the stroke toward a portion of the guidance maps corresponding to the feature of the image the user is intending to draw based feature labels. To further improve the user drawn lines, parametric adjustments are optionally made to the geometrically-corrected stroke to emphasize “correctly” drawn lines and de-emphasize “incorrectly” drawn lines.

A zoom lens barrel capable of attaining a higher photographing magnification by reducing spacing between lens groups in a telephoto state. A first lens group barrel holds a first lens group. A second lens group holding member supported by a third cam barrel holds a second lens group. A spring member urges the holding member toward the first lens group. Cam followers are formed at an opposite end of the holding member from the first lens group. Cam grooves for engagement with the cam followers are formed on the third cam barrel. When the holding member is urged by the spring member in a non-shooting region, each cam groove is brought into contact via one cam surface with the associated cam follower. In a shooting region, the cam groove is brought into contact with the cam follower via two cam surfaces.

A motor vehicle hood lining for stiffening the hood in the vicinity of its periphery and co-operating therewith to form a hollow body over at least a fraction of its periphery, the lining being generally of channel section with a bottom and side walls. Said bottom or at least one of said side walls presents, at least locally, a zone of weakness that is dimensioned in such a manner that in the event of the hood impacting the head of a pedestrian, once the bottom of the hollow body has come to bear against a high hard point placed in the engine compartment, the zone of weakness breaks. The invention also relates to a combination of such a lining with various hard points in an engine compartment.

The linear driving mechanism includes a main body, a linear moving component, a guiding component and a driving component. The main body includes a seat and a moving shaft. The driving component is connected to a rotating shaft of the seat. The moving shaft passes through a driving slot formed on the linear moving component. The guiding component is for guiding a linear movement of the linear moving component. A stroke of the linear moving component of the linear driving mechanism can be changed by approaching or distancing the linear moving component and the seat of the main body to increase or decrease the displacement of the moving shaft located inside the driving slot. Therefore, the linear driving mechanism has not only simple structure but also flexibility in use.

The super-long stroke pumping unit is further energy-saving. Thepump efficiency, yield, annular liquid level position of an oil jacket can be reflected instantaneously by the electric control cabinet. The oil sucking speed or intermittent oil pumping is adjustedautomatically according to liquid supply data to achieve efficient operation, so that purposes of long stroke, low time of strokes, large displacement, intelligent control, optimized oil extraction, extension of periods of replacing a tube rod and examining the pump and remote digitalized control management are achieved.
