摘要： A boom is connected to a support member through a hinge connection which permits both vertical and horizontal movement of the end of the boom. A pneumatic linear actuator, including a cylinder and a piston, is connected between the boom and the support member at the hinge such that the length of the actuator changes with vertical movement of the boom about the hinge support. A bleed-type adjustable pneumatic pressure regulator controls the air pressure applied to the actuator so as to exactly counterbalance the weight of the boom and tools supported on the end of the boom.
摘要翻译：悬臂通过铰链连接件连接到支撑构件，铰链连接允许悬臂端部的垂直和水平运动。包括气缸和活塞的气动线性致动器在铰链处连接在悬臂和支撑构件之间，使得致动器的长度随着吊臂围绕铰链支撑件的垂直运动而变化。排气式可调气动压力调节器控制施加到执行机构的空气压力，以精确地平衡起重臂的重量和支撑在起重臂末端的工具。

摘要： A spray gun discharges air and suspended solid particles through an opening forming a diverging stream. A first pair of nozzles adjacent to the opening form airless sprays of a liquid promoted resin. A second pair of nozzles adjacent to the opening form sprays of liquid catalyst and low pressure air, the stream of particles mixing with the promoted resin and catalyst in front of the spray gun.
