The present invention is directed towards an electrosurgical cutting system. The system comprises an electrically conductive blade, having an uninsulated cutting edge that is surrounded by an insulator. A source of pulsed electrical energy may be coupled to the electrically conductive blade to provide a substantially uniform and highly enhanced electric field along a cutting portion of the blade edge. The blade may have a uniform rate of erosion during use, so that both the conductive metal edge and the surrounding insulation layer erode at approximately the same rate. Also described are methods of fabricating insulated cutting electrodes, particularly blade electrodes.

A surgical saw blade operatively couples to an oscillatory power tool for oscillation about an oscillation axis (OA). The saw blade includes a plurality of cutting teeth separated from one another by a clean out opening along a distal end. The clean out opening comprises an arcuate closed end and straight side walls extending from the closed end. Each tooth comprises first and second rake surfaces and first and second relief surfaces intersecting to define first and second cutting edges, respectively. The first and second cutting edges are oppositely disposed from one another. One cutting tooth protrudes a distance (de) from one side face of the blade and the next adjacent cutting tooth protrudes the same distance (de) from the other side face of the blade to cut a groove having a width (dg) wider than the thickness (t) of the blade.

A cutting arrangement for longitudinally cutting material includes two blades disposed across from one another and which cooperate during cutting. Each blade is embodied as a circular blade having a sharp cutting edge and supported by an adjusting or placement mechanism. During the cutting process, the circular blades are positioned by the adjusting or placement mechanisms so that the cutting edges overlap one another to form an overlap zone, the center of which coincides with the middle of the material that is to be cut. An adaptive control assembly includes individual drive motors for driving each blade and enables constant side load force control for each blade, such that side load pressures are adjustable in response to changes in web sped, web tension, and blade condition in real time. Automatic blade diameter sensors calculate the zero point of the cut, determine the appropriate blade speed and automatically set the overlap.

The invention relates to an inclined transplanting type cassava planting machine and belongs to the field of agricultural machinery. The inclined transplanting type cassava planting machine works in an inclined transplanting mode, sufficient nutrients can be absorbed by cassava, and the machine is applicable to growth and later efficient harvesting of the cassava. Cassava seedlings are transplanted in two rows of a ridge in an inclined manner, and are planted at intervals in a shape of a Chinese character 'Pin', and thus good photosynthesis can be achieved. A fertilizer is deeply applied for one time between two rows of the cassava by using a fertilization furrower, then fertilizer requirements of the two rows of the cassava can be met, and a high fertilizer utilization rate can be achieved. A clamping conveying mechanism is designed in an elastic manner through concave nylon rollers and springs, so that cassava stems are not pressed, and the machine is low in cassava stem damage rate.The cassava stems are cut by using a scissor mechanism, the cut surfaces of the cassava stems are flat, and a low splitting damage rate can be achieved. With the combination of a maltese mechanism and a 'heart'-shaped track disc, uniform cutting and planting can be carried out. The planting machine is capable of carrying out multiple operation items such as fertilization, furrowing, seed stem sowing and automatic soil covering at one time, and is very high in adaptability, simple in structure and easy to popularize.
