摘要： A retarder control valve assembly and system for controlling speed of rail cars, utilizes cartridge valves carried in a manifold body including piping and pilot control apparatus, but no wearing surfaces, dynamic seals, or moving parts. The cartridge valves are replaceable without replumbing, and include all moving valve elements and dynamic seals. The valves each include a piston controlled poppet carried on a spool movable within a cartridge body to open and close the valve and supported to withstand high side loads. The pressure sensing and feedback to the retarder system controller is at the manifold, in a pressure spike attenuating circuit having a phase modulating capability to mimic retarder pressure remotely.

摘要： Apparatus for preventing runaway of trolleys in a power-and-free conveyor system that includes a friction bar that extends lengthwise of the free conveyor track on a side of the track remote from the power conveyor for motion lengthwise of the track at an acute angle to the direction of motion of the trolleys along the track. The friction bar is releasably biased laterally outwardly from the track and in a direction lengthwise of the track opposed to the direction of trolley motion on the track so that trolleys may travel freely along the free conveyor track past the bar. In the event that a trolley is traveling at excessive velocity along the tree conveyor track, the friction bar is moved in the direction of motion of the trolley and at the acute angle laterally into a position for frictional engagement with the trolley on the track, such that momentum of the trolley cooperates with frictional engagement of the bar with the trolley to wedge the bar against the trolley and arrest motion of the trolley on the track. Thus, momentum of the trolley along the track cooperates with angulated motion of the bar into frictional engagement with the trolley for automatically and inherently increasing frictional forces that arrest motion of the trolley on the track.
摘要翻译：用于防止在无电力输送系统中的手推车失控的装置，其包括摩擦杆，所述摩擦杆在远离动力输送机的轨道的一侧沿自由输送轨道的纵向延伸，以沿着轨道纵向运动，以锐角相对于手推车沿轨道的运动方向。摩擦杆从轨道横向向外释放，并且在与轨道上的小车运动方向相反的轨道的纵向方向上可释放地偏置，使得手推车可以沿着自由传送轨道自由行进通过杆。如果手推车沿着树木输送机轨道以超速的速度行进，则摩擦杆沿着小车的运动方向移动并且以锐角侧向移动到与履带上的手推车摩擦接合的位置，例如手推车的动量与杆与手推车的摩擦接合相配合，以将杆抵靠手推车并且阻止手推车在轨道上的运动。因此，沿着轨道的手推车的动量与杆的角度运动配合，与手推车摩擦接合，以自动地并且固有地增加阻止手推车在轨道上的运动的摩擦力。

摘要： This invention relates to a controllable railway skate car retarder including a plurality of levers pivotally supported on the cross ties and disposed on the respective sides of a track rail. The pivotal levers support elongated braking elements which are disposed parallel to the track rails. Each of the outer levers of the car retarder is operated by a power actuator. Each power actuator includes a fluid operated piston and cylinder as well as a mechanical toggle linkage to raise and lower the levers to cause the braking elements to assume a braking or nonbraking position.

摘要： A marshalling yard retarder includes a mechanical braking means with elongated braking members on both sides of the rail movable towards and from the vertical plane of the rail to engage against a wheel rolling on the rail. The braking members are pivoted about horizontal axes and are actuated by hydraulic pistons which are flexibly mounted. The cylinders are supplied by a supply conduit containing a nonreturn valve and a return conduit having a pressure-limiting overflow member which is connected to a storage tank from which the pressure medium is drawn. There may be two pressure-limiting overflow members set for different pressures, and a weighing means for selectively connecting these members to the return line.
