Abstract: A rotary drive shaft disconnect mechanism which mechanically joins two aligned shafts and which disconnects them in response to the overheating of a component element. The mechanism generally comprises two axially aligned, abutting hollow cylindrical elements which are mounted for axial sliding in the driving and driven power shafts. The abutting ends of the cylinders are formed with matching teeth which are maintained in engagement by a preloaded compressive force. Suitable load carrying structure is provided within the cylinders so that a heat responsive fuse transfers the preload compressive force until such time as heat causes the fuse to fail. The fuse is comprised of multiple structural wires which are the elements thereof which transfer the compressive preload. The wires are enclosed in an eutectic matrix. The heat from an overheating component is transmitted to the eutectic which liquefies and removes the side support from the wires which then fail in a columnar bending mode, removing the load path for the compressive preload which allows the disconnection.
Abstract translation: 旋转驱动轴断开机构，其机械地连接两个对准的轴，并且响应于元件的过热而将它们断开。 该机构通常包括两个轴向对齐的邻接的中空圆柱形元件，其被安装用于在驱动和从动动力轴中的轴向滑动。 气缸的邻接端部形成有匹配的齿，其通过预加载的压缩力保持接合。 在气缸内提供合适的承载结构，使得热响应的熔断器转移预压力，直到热导致熔丝失效的时间。 保险丝由多个结构线组成，其是其转移压缩预载荷的元件。 电线被包围在共晶矩阵中。 来自过热部件的热量被传送到共晶体，该共晶体液化并从线中除去侧支撑件，然后以柱状弯曲模式失效，去除允许断开的压缩预载荷的载荷路径。

Abstract: A reversible reciprocating motor pump for transferring energy from one hydraulic system to another. The motor pump includes a pair of similar hydraulic cylinders connected back to back and controlled by interconnected control valves that properly sequence and phase the in and out flows to the hydraulic cylinders so hydraulic energy can be transferred from one system to the other without transferring hydraulic fluid therebetween.
Abstract translation: 一种用于将能量从一个液压系统传递到另一个液压系统的可逆往复式电机泵。 马达泵包括一对相似的液压缸，背靠背连接并由相互连接的控制阀控制，从而使流入液压缸的流入和流出顺序顺序和相位相同，因此液压能量可以从一个系统传递到另一个系统而不传输液压油 之间。

Abstract: A centering and damping cylinder which includes a primary piston for damping and a secondary piston for trim, each piston being of the differential area type and slidable within an internally stepped cylinder housing. In addition to a damping orifice in the primary piston, an internal relief valve may be provided within the cylinder for relieving pressure when the damping orifice cannot handle the required damping flow rate.
Abstract translation: 一种定心和阻尼缸，其包括用于阻尼的主活塞和用于修整的次级活塞，每个活塞具有差速区域类型并且可在内部阶梯式气缸壳体内滑动。 除了主活塞中的阻尼孔之外，当阻尼孔不能处理所需的阻尼流速时，可以在气缸内设置内部溢流阀，以缓解压力。

Abstract: A multi-stage, three port valve in which input commands are fed to a first stage which normally modulates the flow of medium to an actuator. During high demand conditions, differential pressures generated within the valve cause one or more other stages of the valve to automatically supplement medium flow as required.
Abstract translation: 多级三通阀，其中输入命令被馈送到通常将介质流动调节到致动器的第一级。 在高需求条件下，阀内产生的压差会导致阀的一个或多个其他级别，根据需要自动补充介质流量。
