摘要： An elevator overspeed system designed to work as a governor includes a first switch responsive to an overspeed condition and a second, remotely located switch responsive to said first switch. An overspeed elevator control procedure is initiated when one of the first or second switches are tripped. The first switch is automatically re-set after the second switch is tripped. The second switch is manually re-set to re-start the elevator system in normal operation mode.

摘要： A collection and draining system for use in a manufacturing process. This system comprises a collection tank coupled with a collector, the collector consisting of a funnel and a stem. The stem of the collector extends sufficiently into the collection tank such that the bottom of the stem is always covered with the solvent being collected during normal operations of the collection system. This is accomplished by locating the drain in the collection tank above the bottom of the stem. This results in reduced build up of solvents along the walls of the collection tank and the collector. In addition, by allowing the drain of the collection tank to drain into a main drain system, removal of the collection tank from a machine it is attached to during operation of the machine is unnecessary. Removal is only necessary during cleaning of the collection tank or the collector.
摘要翻译：用于制造过程的收集和排放系统。该系统包括与收集器耦合的收集罐，收集器由漏斗和阀杆组成。收集器的杆充分延伸到收集罐中，使得在收集系统的正常操作期间，茎的底部总是被溶剂收集。这通过将收集罐中的排水管置于杆的底部之上来实现。这导致沿着收集罐和收集器的壁的溶剂堆积减少。此外，通过使收集箱的排水口排入主排水系统，不需要在机器的操作期间从其附接的机器移除收集箱。只有在清洗收集罐或收集器时才需要清除。

摘要： A sprinkler head has an inlet to receive a fluid from a pipeline, and a nozzle to spray the received fluid. In one embodiment, a body that couples the inlet to the nozzle includes an electromechanical fluid flow control device via which to vary an amount of fluid pressure presented to the nozzle. In another embodiment, the nozzle includes an electromechanical aperture via which to vary a flow of the received fluid. An electromechanical wheel coupled to the nozzle rotates the nozzle in a direction.

摘要： A roller guide for improving the movement of an elevator car on T-shaped guide rails. The roller has first and second wheels rotatably mounted on an elevator car and spring biased to rollably engage the sides of the nose portion of a T-shaped guide rail. A bumper is secured between the wheels to slidably engage the edge of the nose portion of the T-shaped guide rail and minimize lateral sway of the elevator car as it travels. The bumper also allows for the inventive roller guide to be used to replace the sliding guides of certain types of elevators without exceeding the maximum throat clearance. The roller guide, when installed, is dimensioned to meet the required safety tolerances of the elevator and allow for safe operation of the elevator safeties.
摘要翻译：一种用于改善电梯轿厢在T形导轨上的运动的滚轮导轨。辊具有可旋转地安装在电梯轿厢上的第一和第二轮，并且被偏压以可滚动地接合T形导轨的鼻部的侧面的弹簧。保险杠固定在车轮之间，以可滑动地接合T形导轨的鼻部的边缘，并使电梯轿厢行进时的侧摆动最小化。保险杠还允许本发明的滚子引导件用于替代某些类型的电梯的滑动导轨，而不超过最大的喉部间隙。滚子导轨安装时的尺寸可以满足电梯所需的安全公差，并允许电梯安全装置的安全运行。
