    Abstract: A sediment indicator for installation in a fluid flow line of a fluid circulatory system, such as a liquid cooling system for an internal combustion engine to provide a visual indication of when the fluid medium has become dirty and is in need of cleaning or replacement. The indicator includes the tubular open ended member insertable in a fluid flow line of the circulatory system to provide a fluid passage that is in fluid communication with the flow of fluid in a system. The indicator includes a housing portion having a sediment collecting chamber open to the flow passage of the tubular member and in depending relationship to it. The housing is at least partially transparent to permit visual inspection of the chamber. A washer having a hole smaller than the sediment collecting chamber restricts the rate of movement of sediment into the chamber. Sediment entrained in the circulating fluid medium as it passes in the fluid passage of the tubular member drops under the influence of gravity through the hole in the washer into the chamber where it can be viewed from without the housing. Collection of a predetermined amount of sediment in the chamber is indicative that fluid medium needs to be cleaned or replaced.

    Abstract translation: 用于安装在流体循环系统的流体流动管线中的沉淀物指示器，例如用于内燃机的液体冷却系统，以提供流体介质何时变脏并需要清洁或更换的可视指示。 指示器包括可插入到循环系统的流体流动管线中的管状开口端部件，以提供与系统中的流体流动连通的流体通道。 该指示器包括壳体部分，其具有通向管状构件的流动通道的沉积物收集室并且与其成一定关系。 壳体至少部分透明以允许目视检查腔室。 具有小于沉积物收集室的孔的垫圈限制沉淀物进入室的运动速率。 在循环流体介质中夹带的沉积物在其通过管状部件的流体通道的过程中，在重力的影响下通过垫圈中的孔落入室中，从而可以在没有外壳的情况下观察。 在室中收集预定量的沉淀物指示需要清洁或更换流体介质。

    Abstract: A string trimmer equipped with a knife and deflector apparatus mounted on the shroud directs cut debris laterally away from a workperson operating the string trimmer. A knife cutting edge located below the shroud cuts vegetation moved by the revolving string into cut debris. An upwardly extended radial deflector mounted on the shroud directs the cut debris laterally away from the shroud and workperson.

    Abstract: A motor vehicle speed control system for attenuating sudden unintended acceleration and maintaining driver control of a motor vehicle has a brake switch connected in series with a vacuum switch and a relay. A foot pedal when depressed actuates the brake switch to provide electric power to the vacuum switch coupled to the intake manifold of the motor vehicle. Vacuum pressure in the intake manifold actuates the vacuum switch to close the electric circuit to the relay. Relay interposed in the electric ignition or fuel injector circuits is open when both brake and vacuum switch are closed thereby interrupting these circuits and reducing the power or terminating the operation of the motor vehicle's engine.

    Abstract translation: 用于衰减突然的非预期加速度并维持机动车辆的驾驶员控制的机动车辆速度控制系统具有与真空开关和继电器串联连接的制动开关。 当按下踏板时，致动制动开关以向耦合到机动车辆的进气歧管的真空开关提供电力。 进气歧管中的真空压力启动真空开关以闭合继电器的电路。 当制动和真空开关闭合时，插入电气点火或燃料喷射器电路的继电器断开，从而中断这些电路并降低功率或终止机动车辆发动机的运行。
