    摘要： A mixing head for a reaction injection molding machine, which incorporates several beneficial features, comprises a body having a bore, which defines a mixing chamber, and a plurality of nozzle orifices opening into the mixing chamber for conducting reactive polymeric components thereto. A plunger is mounted for reciprocal movement in the mixing chamber to control flow of the reactive components through the nozzle orifices to form a homogeneous polymer mix, e.g. a polyurethane or polyisocyanurate mix, in the chamber, and serves also to eject the resulting mix from the chamber. The plunger is controlled by an actuator piston and is linked thereto by a universal coupling that minimizes plunger binding in the mixing chamber due to misalignment between the plunger and actuator. The plunger is also sheathed in a sleeve of antifrictional material that permits maintaining a very tight piston fit without excessive friction, and thus resists build-up of reactive material which is a common cause of plunger "freezing" or excess wear. Flow of polymeric components through individual nozzle orifices is regulated by a restrictor valve for each component which includes a packing gland-retainer assembly as well as a position locking arrangement. Accordingly, the restrictor valve may be adjusted without leakage while the mixing head is in operation or while the polymeric composition is under pressure.

    摘要翻译： 用于反应注射成型机的混合头包含若干有益特征，包括具有限定混合室的孔的主体和通向混合室中的多个喷嘴孔，用于将反应性聚合物组分导入其中。 安装柱塞用于在混合室中往复移动以控制反应性组分通过喷嘴孔的流动，以形成均匀的聚合物混合物，例如， 聚氨酯或聚异氰脲酸酯混合物，并且还用于将所得混合物从室中排出。 柱塞由致动器活塞控制，并通过通用联轴器连接，该通用联轴器由于柱塞和致动器之间的未对准而使混合室中的柱塞结合最小化。 柱塞也被套在一种耐磨材料的套筒中，允许在没有过度摩擦的情况下保持非常紧密的活塞配合，从而抵抗反应性材料的积聚，这是柱塞“冷冻”或过度磨损的常见原因。 通过独立喷嘴孔的聚合物组分的流动由用于每个部件的限流阀调节，每个部件包括填料压盖保持器组件以及位置锁定装置。 因此，可以在混合头处于运行中或当聚合物组合物处于压力下时调节限流阀而不泄漏。

    摘要： An improved system for coupling together two objects, particularly sea-going vessels, while permitting relative and at least limited movement in at least three axes -- roll, pitch and yaw -- with a one or more vertical elements mounted on the stern of one towing vessel each coupled to a horizontal element mounted on the bow of a second towed vessel to permit formation of a sea-going barge train pulled by a tug. The horizontal element includes a fluid-tight housing which is mounted for limited lateral movement and which defines an internal chamber in which a piston member and an attached rod move. The rod extends outboard to connect to the vertical element and specifically to one of a pair of concentric vertical members, the other of which is fixedly mounted on the towing vessel. The vertical members move slidably in a vertical direction with respect to each other. The piston of the horizontal element divides the chamber into first and second sub-chambers which are coupled to pneumatic or hydraulic sources which supply fluid or gas to damp piston movement and/or aid in steering. A lateral damping member may be connected to each housing of the horizontal element, particularly when only two couplers are mounted on opposite sides of the vessels. A rigid center coupler flanked by the two piston couplers can be used on larger barges in place of the two side couplers, and also effectively minimizes lateral movement.

    摘要： A cable splice comprises a casing with a tapered bore portion and a tapered jaw cluster therein for gripping the cable. The jaws of the jaw cluster engage a piston that is slidable in a cylindrical bore portion of the casing and also has a central cavity to receive the cable when the latter is installed in the splice. Hydraulic fluid may be introduced into the casing to bias the piston in a direction to cause the jaws to bite into and permanently grip the cable, after which the fluid is withdrawn from the casing.
