摘要： A method of induction heat treatment of articles having curved outer surfaces, such as differential housings. The method employs a semi-rectangular induction coil that is adapted to provide a plurality of lateral magnetic fields that are used to induce currents in, and thereby provide heat to, a portion of the curved section of the article. The method and induction coil are particularly adapted to provide an induction hardening heat treatment of a curved heat treatment portion of a differential housing. The differential housing was cast from nodular iron. The induction-hardening heat treatment comprised heating the heat treatment portion of the differential housing above the austenite transition temperature and quenching to below the martensite transformation temperature.

摘要： A telescoping device uses pins resting in grooves to serve as stop means for telescoping tubes. Each of a set of telescoping tubes has at least one groove running longitudinally along the outer tube circumference. A set of two right angled pins rests in a groove, the first pin extending outward through an aperture in the next largest tube's wall, the second pin extending inwardly through a groove aperture to serve as a stop for the next smallest tube. When the tubes are collapsed inwardly, the progress of each tube is stopped by the second pin in the next largest tube. When the tubes are extended outwardly, the progress of each tube is stopped by the abutting of the first and second pins' ends in a groove.
摘要翻译：伸缩装置使用凹槽中的销钉作为伸缩管的止动装置。一组伸缩管中的每一个具有沿着外管圆周纵向延伸的至少一个凹槽。一组两个直角销钉放置在槽中，第一销向外延伸穿过下一个最大管壁中的孔，第二销向内延伸穿过槽孔，用作下一个最小管的止动件。当管子向内折叠时，每个管子的进度由下一个最大管中的第二个销钉停止。当管向外延伸时，通过第一和第二销的端部抵接在槽中来阻止每个管的进展。

摘要： The subject invention involves a device for sensing the depth to which a worn railroad wheel must be machined in order to reclaim the wheel tread and flange contour. The device consists of an assembly of gaging elements mounted on a support block which is, in turn, mounted on a guide rail for radial movement into contact with the wheel tread. The gaging elements include a flange edge contactor slidably mounted on the support block, a tread contactor slidably mounted on the flange edge contactor, and a flange contacting finger pivotally mounted to the tread contactor. In operation the assembly is moved radially toward the wheel until the wheel tread is contacted. The tread contactor thereafter retracts, causing the flange contacting finger to engage the gaging point on the wheel flange. Further, downward movement of the assembly causes the flange edge contactor to move into engagement with the wheel. Appropriate encoders are connected to the gage assembly to generate pulses which indicate the position of the flange edge and the new diameter to which the wheel is to be machined.
摘要翻译：本发明涉及用于感测磨损的铁路车轮必须加工的深度的装置，以便回收轮胎胎面和凸缘轮廓。该装置由安装在支撑块上的测量元件的组件组成，该组件又安装在导轨上，用于径向移动以与轮胎胎面接触。测量元件包括可滑动地安装在支撑块上的凸缘边缘接触器，可滑动地安装在凸缘边缘接触器上的胎面接触器和可枢转地安装到胎面接触器的法兰接触指状物。在操作中，组件朝向车轮径向移动，直到车轮踏面接触。然后，胎面接触器缩回，导致凸缘接触指状物接合车轮凸缘上的标定点。此外，组件的向下运动导致凸缘边缘接触器移动成与车轮接合。适当的编码器连接到量规组件以产生指示凸缘边缘的位置和车轮将被加工到的新直径的脉冲。
