摘要： An apparatus controllably moves the forks of a material handling vehicle in traverse directions relative to a carriage assembly. The carriage assembly includes fork position sensors which detect the transverse location of each fork. A controller receives signals from the position sensors and moves the forks to locations a preselected or calculated distance apart. Forktip sensors detect the opening in a load during movement of the forks. The controller receives signals from the forktip sensors and positions the forks such that they are disposable within the load opening. The apparatus is especially suitable for use on an Automatic Guided Vehicle (AGV).

摘要： A control system for a fluid operated jack reduces the speed of retraction of a piston rod of the jack to an acceptable rate during a preselected range of operation by adding pressurized fluid flow to the fluid being exhausted from the jack through a restrictor valve to the reservoir. This reduction in speed reduces the potential for damage to the jack and associated componentry without sacrificing efficiency of operation. An implement controller causes fluid flow from a fluid source to be combined with the flow of fluid being exhausted from the jack in response to receiving a position signal from a implement position sensor and subsequent to the implement controller commanding the shifting of a control valve to a position at which fluid flow is passed from the fluid operated jack to the reservoir. The control system is particularly suitable for use on an automatic guided vehicle.
摘要翻译：用于流体操作的千斤顶的控制系统在预选的操作范围内将千斤顶的活塞杆的回缩速度降低到可接受的速率，通过将压力流体流通过限流阀向储液器排出的流体。这种降低速度降低了对插孔和相关组件的损坏的可能性，而不会牺牲操作效率。响应于接收来自工具位置传感器的位置信号并且在指示将控制阀移位到控制阀的工具控制器之后，工具控制器使得流体从流体源流出的流体与从插座排出的流体流合并流体流动从流体操作的千斤顶到储存器的位置。该控制系统特别适用于自动引导车辆。

摘要： A method and apparatus for determining a leak in an HC fluid supply of an exhaust purification system for an engine is disclosed. The fluid supply includes an injector that injects an amount of a NOx reducing fluid, a tank that holds the NOx reducing fluid, and a pump that pressurizes the NOx reducing fluid. The system fluid pressure is read before and after the pump is shut off. The pressure readings are compared and the exhaust purification system is turned off in response to the difference between the pressure readings being greater than a predetermined value.

摘要： A generator set controller verifies the status of a synchroscope mode selector to determine whether the generator set controller is operating in a synchroscope mode. When operating in a synchroscope mode, the generator set controller uses an existing display panel to create an indication of the difference between the phase of the power on a power bus and the phase of the power output of the generator.
