摘要： An endless power transmission chain-belt constructed of joined sets of links and blocks surrounding sets of links, the links in some sets having a pitch larger than links in other sets. Some blocks are of such width to engage pulley flanges of a pulley transmission while other blocks are of a lesser width to "skip" the flange engagement. The latter blocks can be omitted, if desired.

摘要： A series vibration damper assembly which includes a control device that will allow the damper to react differently in the coast direction than in the drive direction. The vibration damper assembly includes a housing having inwardly offset drive straps, a hub having radial arms aligned with the drive straps in a static condition, a plurality of spring separators positioned between the hub arms and separating damper springs received between the hub arms. The improvement of the present invention relates to a curved bypass thrust member secured to each hub arm and projecting through two damper springs and the spring separator to abut the next spring separator and prevent compression of the two springs in the coast direction.

摘要： By simultaneously charging a pair of capacitors from the same low voltage level to the same high reference voltage level, the two charge time durations will be functions of and will be proportional to the capacitances of the two capacitors. A comparison of those charge time durations will thus provide an indication of the ratio of the capacitances of the two capacitors. This is achieved by including, in the measuring system, an oscillating circuit whose frequency is determined by the capacitance of one of the capacitors. A periodically-recurring rectangular wave is then developed having pulse components with pulse widths determined by the capacitance of the other capacitor, the frequency of the rectangular wave being equal to the oscillating frequency. The duty cycle of the rectangular wave is therefore proportional to and respresents the ratio of the capacitances of te capacitors. By averaging the rectangular wave in a low-pass filter, an output signal is produced having an amplitude which is proportional to and represents the capacitance ratio.
摘要翻译： 通过将一对电容器从相同的低电压电平同时充电到相同的高参考电压电平，两个充电时间持续时间将是两个电容器的电容的函数并将成正比。 因此，这些充电时间持续时间的比较将提供两个电容器的电容的比率的指示。 这通过在测量系统中包括其频率由电容器之一的电容确定的振荡电路来实现。 然后开发周期性重复的矩形波，其具有由另一电容器的电容确定的脉冲宽度的脉冲分量，矩形波的频率等于振荡频率。 因此矩形波的占空比与电容器的电容的比例成比例，并且表示电容的电容比。 通过对低通滤波器中的矩形波进行平均，产生具有与电容比成比例的振幅的输出信号。

摘要： A centrifugally-actuated roller clutch or overrunning clutch acting to engage two shafts rotating independently at different speeds to bring them into engagement in one or both directions at a predetermined rpm. The clutch assembly includes an outer race, a wave hub or inner race, clutch rollers, a spacer ring or spacer blocks to separate the rollers and a garter spring encompassing the rollers. If a freewheeling mode is required in one direction, the spacer ring or blocks are not required, and the wave form of the inner hub controls the overrunning action.

摘要： An anti-clash and anti-rattle brake for a multiple speed ratio transmission is engageable to apply a frictional braking force to the constantly meshed gears when a shift control device is in a free neutral position. The brake is spring biased toward engagement. It is disengaged by one cam device when the shift control device is moved from the free neutral position in one plane and by another cam device when the shift control device is moved from the free neutral position in another plane.

摘要： Apparatus for underfiling curvelinear vanes of cast centrifugal impellers. Such vanes are cast with generally uniform thickness along their length; it is desirable to have the vanes taper in thickness such that the radially outward portions are thinner than the roots; also this provides a desired curve to each side of the blades.

摘要： Magnetically synchronized clutch apparatus includes a jaw clutch and an electromagnetic synchronizer. The jaw clutch has a rotatable sleeve member and a rotatable shift assembly with a shift member. A spring biases the shift member for engagement with the sleeve member. The shift assembly is slidable to a position in which the members remain disengaged when not rotating in approximate synchronism. The electromagnetic synchronizer brings the members into approximate synchronism upon sliding of the shift assembly.
