    摘要： An air-driven dual diaphragm pump comprises a pump body with a first air passage leading to a first air cavity with a first diaphragm, a second air passage leading to a second air cavity with a second diaphragm, and a reciprocating shaft which connects the first and second diaphragms. A diaphragm installation tool for the dual diaphragm pump comprises a plate which fits atop the pump body. A groove in a surface of the plate opposite from and nonadjacent to the pump body extends from the location of the first air passage to the location of the second air passage. A hole located within the groove at the location of either the first air passage or the second air passage extends through the plate. Pressurized air entering the pump body is redirected by the groove and the hole to always enter the first air passage, rather than the second, thereby slowly filling the first air cavity and positioning the second diaphragm for installation.

    摘要： A piston and geared rack assembly are moved by pressurized air in opposite directions within a power cylinder housing as the vehicle operator registers door closing and opening commands in a solenoid valve. This lateral movement is converted to rotary movement by a pinion gear driven by the rack and coupled to turn a spindle shaft which drives the door. At full stroke during door closing, the power piston actuates a valve to charge the lower chamber of an auxiliary cylinder to move a lift piston rod, movable within the spindle shaft, to raise the closed door into a locked position. Upon a door-open command, the solenoid valve exhausts the charged cylinder chambers, admits air into the upper chamber of the auxiliary cylinder to move the lift piston and rod to lower and release the door, and slowly charges the associated opening chamber. This enables the delayed movement of the power piston and rack assembly in the opposite direction, reversing the rotation of the pinion and spindle shaft, to open the door. If air pressure is lost with the door closed and locked, the weight of the door forces the lift piston and rod down, releasing the door from its locked position for emergency manual operation.

    摘要翻译： 当车辆操作员在电磁阀中关闭和打开指令时，活塞和齿轮架组件通过加压空气在动力缸壳体内以相反方向移动。 该横向运动通过由齿条驱动的小齿轮转换成旋转运动，并联接以转动驱动门的主轴。 在关门期间，在整个行程中，动力活塞致动阀门以对辅助气缸的下腔室进行充电，以移动可在主轴内移动的提升活塞杆，以将关闭的门升高到锁定位置。 在门打开命令时，电磁阀对带电气缸室进行排气，将空气引入辅助气缸的上腔室，以移动提升活塞和杆以降低并释放门，并缓慢地对相关的开启室进行充气。 这使得动力活塞和齿条组件沿相反方向的延迟移动，反转小齿轮和主轴的旋转，以打开门。 如果门关闭并锁定时空气压力下降，门的重量会迫使提升活塞和杆向下，将门从其锁定位置释放，以进行紧急手动操作。

    摘要： Means and method of substantially increasing the efficiency of a spark ignition Otto cycle engine. This is done by increasing the stroke length of the pistons and reducing the amount of air (or fuel/air mixture) by means other than the throttle plate taken in on the intake stroke. The amount of air or fuel/air mixture taken in is that which creates the same conditions in the combustion chamber at the conclusion of the compression stroke as exist in prior art engines used for the same application. The advantage arises from the increase in the length of the power stroke; this extracts more energy from the combustion gases before they are removed on the exhaust stroke and it also increases the torque of the engine as it is well known that torque is a function of stroke length. Extracting more energy from the combustion gases also reduces the amount of heat transferred to the engine block, thereby reducing the load on the cooling system.

    摘要翻译： 火花点火奥托循环发动机效率显着提高的手段和方法。 这是通过增加活塞的冲程长度并通过除了在进气冲程中吸入的节流板之外的装置减少空气（或燃料/空气混合物）的量来完成的。 进入的空气或燃料/空气混合物的量是在压缩冲程结束时在燃烧室中产生与在相同应用中使用的现有技术发动机中相同的条件。 优点来自于动力冲程长度的增加; 这在燃烧气体在排气行程上被移除之前从燃烧气体中提取更多的能量，并且还增加发动机的扭矩，因为众所周知，扭矩是行程长度的函数。 从燃烧气体中提取更多的能量也减少了传递到发动机缸体的热量，从而降低了冷却系统的负荷。
