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.

Methods and apparatus provide an input for a user located remote from a cutting machine to cut a part. The user can instruct the cutting machine to cut the part to the user's specification in many ways, for example such that the user can instruct the cutting machine without having knowledge of the machine's cutting processes or construction. The methods and apparatus of the embodiments described herein can convert a machine processes into an image of the part to be cut such that the user can easily view and understand the image of the part to be cut remote from the cutting machine.

The invention relates to a cutting device, in particular to a cloth cutting device for garment processing.

The present invention relates to rounded blade scissors. The rounded blade scissors according to one embodiment of the present invention comprise: a first cutting portion including a first cutting blade bent in one direction to cut a target; a second cutting portion including a second cutting blade having a closed annular or polygonal shape to surround the surface of the first cutting portion; a first frame portion supporting the first cutting portion on one side of the first cutting portion; a second frame portion supporting the second cutting portion on one side of the second cutting portion; and a coupling portion that hingedly couples the first frame portion with the second frame portion so that the first cutting portion comes into contact with the second frame portion through rotation. Therefore, the cutting can be performed in a safe and effective manner. According to the present invention, the cutting target can be cut in an easy, convenient, and safe manner.

The invention discloses a multi-cutter progressive turning machine tool of slender shafts, belongs to the technical field of precision machining, counteracts one-way force of cutters on workpieces during machining, eliminates the deformation condition of slender shaft workpieces caused by centrifugal force generated during centering and machining of the traditional lathe and solves the technical problem that the machining size of the workpieces is limited at the same time. The machine tool comprises a machine tool body unit, a multi-tool machining unit, a left pre-tightening force unit and a right pre-tightening force unit, wherein the left pre-tightening force unit and the right pre-tightening force unit are distributed at the two ends of the machine tool body unit and drive the multi-tool machining unit to reciprocate in the axial direction; and the multi-cutter machining unit is arranged on the machine tool body unit and does reciprocating motion on the machine tool body unit to machine the slender shafts. The main motion of the traditional lathe is workpiece rotation; weak-rigidity tiny slender shafts can generate centrifugal force during rotation to cause workpiece deformation; the main motion of the lathe is improved from traditional workpiece rotation to cutter set rotation by the device; workpiece deformation is avoided; and the machining precision is improved.

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.

A method of constructing upholstered furniture is provided using unitary ends which are covered with molded polymeric foam cushions. The construction method saves time and reduces the cost of the finished furniture while allowing relatively unskilled workers to produce top quality furniture in an efficient manner.
