Abstract: A high pressure liquid nozzle housing encloses a self-rotating speed-controlled nozzle. A cylindrical sleeve in the housing forms an inwardly facing friction surface engageable by a nozzle-driven friction generating speed control mechanism to provide increasing retarding force on the nozzle as nozzle speed increases for controlling maximum nozzle rotational speed. The speed control mechanism includes a radially expandable helical coil spring rotatable with the nozzle with its windings at low nozzle speeds slightly spaced from the sleeve. An input end of the coil spring is driven by the nozzle structure in a direction tending to unwind the spring and increase its outer diameter in response to rotation of the nozzle. An output end of the coil spring rotatably drives a cluster of centrifugal weights which are spring biased away from the sleeve and which at low nozzle rotation speeds also remain spaced from the sleeve. At higher speeds of nozzle rotation the weights move outwardly and frictionally engage the sleeve and provide a drag on the output end of the spring to aid in unwinding the spring, increasing its diameter and moving it with progressively increasing force into friction creating engagement with the sleeve to provide progressively increased retarding force against nozzle rotation as nozzle speed increases. The weights and spring retarding forces combine, but the spring retarding force is several times the retarding at the weights when an equilibrium between retarding forces and opposing jet stream nozzle reaction is reached at maximum nozzle speed.
Abstract translation: 高压液体喷嘴壳体包围自转速度控制的喷嘴。 壳体中的圆柱形套筒形成面向内的摩擦表面，该表面可由喷嘴驱动的摩擦发生速度控制机构接合，以便当喷嘴速度增加以控制最大喷嘴旋转速度时，对喷嘴提供增加的阻力。 速度控制机构包括可旋转的径向可扩张的螺旋弹簧，其喷嘴与其绕组以较低的喷嘴速度与套筒间隔开。 螺旋弹簧的输入端由喷嘴结构沿着倾向于退绕弹簧的方向驱动，并响应于喷嘴的旋转而增加其外径。 螺旋弹簧的输出端可旋转地驱动一组离心重物，其离开套筒弹簧偏压，并且在低喷嘴旋转速度下也保持与套筒间隔开。 在更高的喷嘴旋转速度下，重物向外移动并且摩擦地接合套筒并且在弹簧的输出端上提供阻力以帮助弹簧退绕，增加其直径并随着逐渐增加的力将其移动，从而与套筒 以随着喷嘴速度的增加逐渐增加喷嘴旋转的阻力。 重量和弹簧减速力相结合，但是当以最大喷嘴速度达到减速力和相对的喷射流喷嘴反应之间的平衡时，弹簧减震力是重量处的阻尼的几倍。

Abstract: A nozzle assembly includes a hollow nozzle body having a central bore and a plurality of ports extending through the body from the central bore; a switching valve assembly disposed in the central bore that directs fluid flow to ports upon application of fluid flow above a predetermined threshold to the inlet and direct fluid flow to different ports upon fluid flow having subsequently dropped below the predetermined threshold and then exceeding the predetermined threshold; and a flow insert configured to replace the switching valve assembly for directing flow through all of the ports when switching functionality is not needed. This flow insert may be made of a low pressure material such as a polymer.

Abstract: A system and method for cleaning of heat exchanger tubes including an assembly, an indexer, and a communication device provided with specialized software and programming. The indexer includes orthogonally arranged first and second arms. A trolley and sensors are provided on the indexer arms. One or more lances are provided on the trolley to deliver water jets into the openings. Sensors measure displacement as the trolley is moved relative to the heat exchanger's face plate. An operator controls the system from a distance away using the communication device. During setup, the pattern of the face plate is learned and mapped utilizing information from the sensors as one of the inputs. This information is utilized to help navigate the face plate during a subsequent cleaning operation. A kit for retrofitting existing X-Y indexers is also disclosed.

Abstract: A system for distinguishing target metal objects from each other in close proximity to each other. The method includes transmitting a first sinusoid signal via a first transmit coil to a first receive coil in close proximity to the first transmit coil; transmitting a second sinusoidal signal at a second frequency and amplitude different from the first frequency and amplitude to a second receive coil arranged in close proximity to the second transmit coil and in close proximity to the first receive coil such that received signals in the first and second receive coils include first and second frequency signals from the other of the first and second transmit coils. The received signals are separated via frequency domain multiplexing. The signals are compared to detect a presence of the target having a signal magnitude different from the first received signal and the received second signal and a known reference point.

Abstract: An apparatus for sensing an obstruction within a tube being cleaned and repetitively advancing and retracting a flexible high pressure fluid cleaning lance within the tube is disclosed. The apparatus monitors drive roller/belt position and actual hose position, compares the belt (expected travel) to hose position (travel) and generates a position difference, or mismatch. If the mismatch is above a predetermined level, the drive motor direction is reversed for a predetermined time interval, and forward operation restored after the predetermined time interval; and the sequence of repeating the reversing and restoring operations is continued until the position difference or mismatch no longer exceeds the predetermined difference threshold.
