    摘要： A circular milling cutter for milling a curved groove of constant radius having circumferentially spaced teeth with peripheral cutting edges that lie on a conical surface whose vertex lies on the cutter''s axis and with the ends of these cutting edges spaced from the vertex at distances equal to the radii of the groove''s opposing side walls. The teeth further have either curved side cutting edges with radii from a common point on the cutter axis which intersect the cutting edge ends or straight side cutting edges perpendicular to the peripheral cutting edges. Furthermore, the teeth in one embodiment have relieved flanks on only the side closest to the vertex of the peripheral cutting edges. In simultaneously milling grooves in opposite sides of a part, there are employed two cutters with each cutter axis arranged to intersect the centerline of curvature of the respective groove at an angle where the peripheral cutting edges pass parallel to the respective work surface and the side cutting edges are perpendicular thereto. There is first performed a plunge cut by both cutters to the groove depth while the relative angularity between the cutters and workpiece is maintained whereafter the workpiece is turned about the common centerline of the grooves to effect milling the length of the grooves.

    摘要翻译： 一种用于铣削恒定半径的弯曲凹槽的圆形铣刀，具有周向间隔开的齿，其周边切削刃位于其顶点位于切割器轴线上的锥形表面上，并且这些切削刃的端部与顶点的距离等于 凹槽相对侧壁的半径。 齿还具有弯曲侧切割刃，其具有与切割轴线上的共同点的半径相交的切割边缘端部或垂直于周边切割刃的直边切割刃。 此外，一个实施例中的齿只在最靠近周边切削刃的顶点的一侧具有释放侧面。 在同时在一部分的相对侧铣削槽时，使用两个切割器，每个切割器轴线布置成与相应凹槽的曲率中心线以一定角度相交，其中周边切割刃平行于相应的工作表面和侧面切割 边缘与其垂直。 首先，由两个切割器进行切割到凹槽深度，同时保持切割器和工件之间的相对角度，然后工件围绕凹槽的公共中心线转动以实现凹槽的长度的铣削。

    摘要： The assembly of the rotor and the spring-biased seals carried by the rotor into the housing of a rotary engine is facilitated by applying an adherent, waxy film to the seals and inserting them in the rotor grooves. This film composition adheres to the side of the groove and temporarily holds the spring-biased seals in a recessed position during an assembly operation. However, the properties of the composition are such that the seals self-return after a short time to their normal operating positions for engine starting. Upon brief engine operation the wax composition evaporates and is consumed without residue.

    摘要： A cool-running abrasive cutting tool having a working surface comprising a layer of diamond particles included in a heatconductive matrix and a heat-dissipating region immediately subjacent the working surface. The heat-dissipating region is comprised of a highly porous material having a macroporosity profile, an extended internal heat transfer surface area and preferably is formed from a metal having a thermal conductivity coefficient of at least about 0.05 g.-cal./(sec.) (cm.2) (* C./cm.). A particular electroplated diamond peripheral wheel is disclosed.
