    • An improved power driven conveyance intended primarily for use by handicapped persons or invalids. A power means to drive the conveyance on level surfaces at normal pedestrian speeds and or to ascend or descend conventional or irregular stairways at reduced speed and increased torque. The invention further contains a self-leveling chair which automatically maintains the occupant in a level seated position regardless of the inclined position assumed by the conveyance frame, thereby contributing to the stability of the conveyance and the safety of the occupant. A fail safe tractor belt means is provided to insure a positive grip between the stair treads and the conveyance. Frontal and rear auxiliary tractor belt units adjust the inclination of the main tractor belts to alignment with the angularity of the stairways and landings.
    • 一种改进的动力驱动运输,主要用于残疾人或残疾人使用。 动力是指以正常行人速度驱动水平表面上的运输,并且以降低的速度和增加的扭矩上升或下降常规或不规则的楼梯。 本发明还包括自动调平椅,其自动地将乘员维持在水平就座位置,而与运输框架所假定的倾斜位置无关,从而有助于运送的稳定性和乘客的安全性。 提供了一种故障安全的拖拉机皮带装置,以确保楼梯踏板和运输工具之间的正握力。 正面和后部辅助拖拉机皮带单元调整主拖拉机皮带的倾斜度,使之与楼梯和平台的角度对齐。

    • An improved reciprocatory self-loading dual-ended earth excavation vehicle pivotally connected to two or more unmanned self-leveling and self-maneuvering telescopic conveyor vehicles, the latter in turn are pivotally connected to a multi-function dual-ended distribution vehicle capable of conveying, spreading, wetting, impacting and grading the earth fill. The above-mentioned articulated vehicles provide the means to excavate, convey and discharge a virtually continuous flow of earth while traveling in a forward or rearward direction. The excavation and telescopic conveyor vehicles are readily adaptable to surface mining of various minerals including coal and oil shale by simply exchanging the abovementioned distribution vehicle for a pivotally connected boom conveyer vehicle which provides the means for discharging the ore at a mill site or for the loading of long haul ore carriers.
    • 一种改进的往复自加载双端土方挖掘车辆,其枢转地连接到两个或更多个无人自动平整和自动操纵的伸缩式输送车辆,后者又枢转地连接到能够输送的多功能双端口配送车辆 ,扩散,润湿,冲击和分级地球填充。 上述关节式车辆提供了在向前或向后方向行进时挖掘,输送和排放实际上连续的地球流的装置。 挖掘和伸缩式输送车辆通过简单地更换上述分配车辆用于可枢转地连接的悬臂输送机车辆,容易地适用于各种矿物包括煤和油页岩的表面采矿,其提供了在碾磨现场排放矿石的装置或用于装载 的长途运输船。
