摘要： Method and apparatus for stock dividing gear-shaped workpieces mounted on the work spindle of a gear-finishing tool. A work spindle encoder provides instantaneous angular position information when the surface of leading and trailing flanks of the workpiece teeth are sensed by a probe. This instantaneous position information is used to generate two sets of measured error values which relate, respectively, to the leading and trailing flanks and which are indicative of the differences between the sensed surrfaces and the desired surfaces of a correctly-sized gear. These sets of error values are analyzed using fourier transform techniques to generate (a) a first harmonic for each set and (b) a set of modified error values for each leading and trailing flank corresponding to each respective first harmonic. The largest and smallest modified error values of each set are used to simulate the opposite sides of the largest and smallest "effective" (as different from "actual") tooth spaces of the unfinished workpiece, and these effective spacings are compared to the desired correctly-sized tooth space of a finished gear to generate a correction value for adjusting the angular position of the workpiece relative to the finishing tool prior to initiation of the finishing process. In the preferred embodiment, a non-contact probe is used for sensing the flanks of the workpiece so that the entire stock division procedure takes only a relatively few seconds.

摘要翻译： 安装在齿轮精加工工具的工作轴上的齿轮状工件的分割方法和装置。 工件主轴编码器在通过探头感测工件齿的前后侧面的表面时提供瞬时角位置信息。 该瞬时位置信息用于产生两组测量的误差值，这两组测量误差值分别与前导和后部侧面相关，并且表示感测到的表面与正确尺寸的齿​​轮的所需表面之间的差异。 使用傅里叶变换技术来分析这些误差值集合，以产生（a）每个集合的一次谐波，和（b）对应于每个相应的第一谐波的每个前导和后端的一组修正的误差值。 每组的最大和最小的修正误差值用于模拟未完成工件的最大和最小“有效”（与实际“不同于”实际“）齿空间的相对侧，并将这些有效间距与正确地进行比较 成品齿轮的齿形间距产生用于在开始精加工之前调整工件相对于精加工工具的角位置的校正值。 在优选实施例中，使用非接触式探针来感测工件的侧面，使得整个分割程序仅需要相对较少的秒。

摘要： Each open liquor bottle in a tavern has a plastic spout with a magnetically operable valve to control the flow of liquor from the bottle. The spouts were fabricated with three integral rings extending around the spout with each ring being either plastic or metal to form a pattern that encodes information identifying a characteristic of the bottle. An annular actuator reads the pattern of rings and responds by producing a magnetic field that opens the spout valve to dispense the liquor. Three rings allow up to eight different classes of characteristics to be encoded. To increase that number of classes a supplemental metal ring is attached around some of the spout adjacent to one end of the actuator when the spout is inserted therein. The actuator is modified to sense presence of the supplemental metal ring on a spout. Adding another ring to certain spouts permits the number of classes of characteristics to be doubled without requiring replacement of existing spouts in a tavern.

摘要： A separate spout is attached to each open bottle in a tavern with each spout having a magnetically operable valve to control the flow of liquor from the bottle. A transponder is provided in each spout transmits an unique identification code. To pour liquor from a bottle, an actuator is placed over the spout. An interrogator coupled to an interrogator coil in the actuator for sending an activation signal to the transponder and thereafter reads the identification code. A memory provides a group of storage locations for each of the plurality of spouts. The group of storage locations for a given spout contains the identification code for that spout and data regarding a total volume dispensed from a particular bottle to which the given spout is attached, a quantity present in the particular bottle when full, and a price per volume unit. A controller energizes a valve operating coil in the actuator to open a valve in response to the interrogator reading the identification code from a spout. Upon energizing the valve operating coil, the controller accesses the memory and updates data in the group of storage locations which contain the identification code read from a spout. The system accounts for the amount of liquor dispensed from each bottle and the value of that liquor to monitor the liquor inventory and sales.
