摘要： In a vehicle locating apparatus that utilizes Hall effect generators to determine the magnetic heading of the vehicle there is provided magnetic compensation by the placing of a coil around the Hall generators. A current source generator provides power to the coil of such magnitude so as to create a magnetic field which cancels the spurious local magnetic field components. The appratus also includes a set of manual switches to program a constant number into the system. The system incorporates this number to compensate for variable wheel diameters and to allow the selection of variable map scale units. This number is utilized by the system in a division technique that repeatedly subtracts the number or adds the number to the accumulated distance traveled by the vehicle. The location of the vehicle is updated as the vehicle passes a transmitting signpost. Data transmitted to and from the vehicle locating apparatus is in a self-clocking format that reduces oscillator accuracy requirements. The system also includes a second set of manual switches for inputting a rotation angle. A variable time delay circuit incorporates this rotation angle to electronically increase or decrease the measured magnetic heading angle. This electronic rotation provides for a method to correct physical misalignment of the heading sensor in the vehicle and to compensate for local magnetic deviation.
摘要翻译：在利用霍尔效应发电机来确定车辆的磁道的车辆定位装置中，通过在霍尔发电机周围放置线圈来提供磁补偿。电流源发生器向线圈提供这样的大小的功率，从而产生消除杂散局部磁场分量的磁场。该应用程序还包括一组手动开关，用于将常数编入系统。该系统采用这个数字来补偿可变轮径，并允许选择可变地图刻度单位。该系统以分割技术利用该数字，其重复地减去该数量或将车辆的行驶距离加到该车辆的行驶距离上。当车辆通过发射路标时，车辆的位置被更新。传输到车辆定位设备的数据是自定时格式，可以降低振荡器精度要求。该系统还包括用于输入旋转角度的第二组手动开关。可变时间延迟电路结合该旋转角度以电子地增加或减小测量的磁性方向角。该电子旋转提供了一种校正车辆中的航向传感器的物理不对准并补偿局部磁偏差的方法。

摘要： A closure including a rigid thermoplastic member with a horizontally extending first portion occupying a major portion of the cross-sectional area within the loading aperture which is surrounded by the loading member of the hopper car, a second portion extending upwardly from the first portion which is inwardly adjacent of the interior of the loading member and a third portion extending outwardly from the second portion and overlaying the top of the loading member and underlaying the hatch cover of the hopper car when the hatch cover is in its closed position. Also a flexible plastic member overlaying the rigid thermoplastic member and the loading member and underlaying the hatch cover when the hatch cover is in its closed position.
