    • A cutting tool for improved material removal efficiency at relatively high feed rates is disclosed. In a preferred form of an indexable polygonal cutting insert, an edge land and chip contacting ramp surfaces in at least a top face of the insert are advantageously arranged for reduced cutting forces and friction, ample cutting edge strength and inducement of free chip flow. In order to overcome deleterious chip convergence and resultant high pressures in the vicinity of the nose radius of the cutting corner of the insert, a recessed control surface is positioned in each corner portion of the polygonal insert.

    • A hydraulic pump having a cylinder closed at one end with an elongated piston arranged within the cylinder from the other end. The piston is constructed of a positive magnetostrictive material which increases in length in the presence of a magnetic field of appropriate intensity. It is wound along its length with a coil of wire capable of producing an electro-magnetic field upon energization. The piston is fastened at the open end of the cylinder to define a cylinder cavity between the cylinder closed end and the piston. A pair of passages including valves, for use as an intake and an exhaust passage, communicate with this cavity. The valve members in each cavity comprise a magnetically polarized member, each of opposed polarity as related to the other, such that upon energization of the pump with one polarity of pulses, the valves will assume a particular function, and with a reversed polarity of operating pulses, a reverse function. The volume of this cavity is reduced when the piston expands under the influence of the magnetic field created by the coil to produce a pressure on any fluid contained within said cavity to force it out the exhaust passage. In a preferred embodiment the cylinder is constructed of a negative magnetostrictive material which contracts or shrinks in length in the presence of magnetic field.

    • A magnetostrictive hydraulic injector pump having a cylinder closed at one end with an elongated piston arranged within the cylinder from the other end. The piston is constructed of a magnetostrictive material which increases in length in the presence of a magnetic field of appropriate intensity. It is wound along its length with a coil of wire capable of producing an electro-magnetic field. The piston includes an intake passage communicating with a fluid supply. The piston is fastened at the open end of the cylinder to define a cylinder cavity between the cylinder closed end and the piston. An injector passage including a valve, communicates with this cavity to the exterior. The volume of this cavity is reduced when the piston expands under the influence of the magnetic field created by the coil to produce a pressure on any fluid contained within said cavity to force it out the injector passage.In a preferred embodiment the cylinder is constructed of a negative magnetostrictive material which contracts in length in the presence of a magnetic field. Thus, upon the energization of the coil the cylinder shrinkage and the pistons expansion double the relative movement of the piston face to increase the volume displacement of the pump.
    • 一种磁致伸缩液压喷射器泵,其具有在一端闭合的气缸,其中细长活塞从另一端设置在气缸内。 活塞由在适当强度的磁场的存在下长度增加的磁致伸缩材料构成。 它的长度是用能够产生电磁场的线圈缠绕的。 活塞包括与流体供应连通的进气通道。 活塞被紧固在气缸的开口端,以在气缸闭合端和活塞之间限定气缸腔。 包括阀的喷射器通道与该空腔连通至外部。 当活塞在由线圈产生的磁场的影响下膨胀时,该空腔的体积减小,以对包含在所述空腔内的任何流体产生压力,以将其压出喷射器通道。 在优选实施例中,圆筒由负磁致伸缩材料构成,该磁致伸缩材料在存在磁场的情况下长度收缩。 因此,在线圈通电时,缸体收缩和活塞膨胀使活塞面的相对运动增加一倍以增加泵的体积位移。

In an alternate embodiment the piston is constructed of a magnetostrictive material which decreases in length in the presence of a magnetic field of appropriate intensity. In a further embodiment the cylinder is constructed of a negative magnetostrictive material which contracts or shrinks in length in the presence of a magnetic field. The volume of the cylinder cavity is reduced when the piston expands and the cylinder shrinks under the influence of the magnetic field created by the coil to produce a pressure on any fluid to force it out the exhaust passage.
    • 一种液压泵,其具有在一端封闭的泵气缸,其中细长活塞从另一端设置在气缸内。 活塞由在适当强度的磁场的存在下长度增加的磁致伸缩材料构成。 沿着长度方向缠绕能够产生电磁场的线圈。 活塞被紧固在气缸的开口端,以在气缸闭合端和活塞之间限定气缸腔。 一对通道,包括阀,进气和排气通道阀与该腔连通。 当活塞在由线圈产生的磁场的影响下膨胀时,该空腔的体积减小,以对包含在所述空腔内的任何流体产生压力,以迫使其排出通道以启动液压缸。 在替代实施例中,活塞由在适当强度的磁场的存在下在长度上减小的磁致伸缩材料构成。 在另一实施例中,气缸由负磁致伸缩材料构成,该磁致伸缩材料在存在磁场的情况下在长度上收缩或收缩。 当活塞膨胀并且气缸在由线圈产生的磁场的影响下收缩时,气缸腔的体积减小,以产生对任何流体的压力,从而迫使其排出通道。
