摘要： Eyes in adjacent track segments in a bulldozer type track are secured to each other by a pin which is provided with a grease fitting and connecting passages for communicating lubricant to the bearing surfaces in the linkage. The pins are housed in a metal sleeve which cooperates with resilient seals to retain the lubricant in the linkage and to keep external matter away from the linkage bearing surfaces. The pin is held in place by removable retaining means so that the linkage may be separated and reattached without special equipment.

摘要： A real-time learning (RTL) neural network is capable of indicating when an input feature vector is novel with respect to feature vectors contained within its training data set, and is capable of learning to generate a correct response to a new data vector while maintaining correct responses to previously learned data vectors without requiring that the neural network be retrained on the previously learned data. The neural network has a sensor for inputting a feature vector, a first layer and a second layer. The feature vector is supplied to the first layer which may have one or more declared and unused nodes. During training, the input feature vector is clustered to a declared node only if it lies within a hypervolume defined by the declared node's automatically selectable reject radius, else the input feature vector is clustered to an unused node. Clustering in overlapping hypervolumes is determined by a decision surface. During testing of the RTL network, the same strategy is applied to cluster an input feature vector to declared (existing) nodes. If clustering occurs, then a classification signal corresponding to the node is generated. However, if the input feature vector is not clustered to a declared node, then the second layer outputs a signal indicating novelty. The RTL neural network is used in a perceptive system which alternatively selects the RTL network novelty output or the output of a classifier trained on historical target data if the input vector is a subset of the historical target data.

摘要： The assembly is supported and operated by a tubing string and includes an hydraulically set packer carrying a production screen and a removable gravel pack apparatus. The packer is set, gravel is packed about the screen and the gravel pack apparatus is then removed from the set packer by disengaging a pin and slot connection. The gravel pack apparatus and attached screen may be subsequently re-engaged with the packer for regraveling. The packer is equipped with resilient seal means and a plurality of radially movable anchoring slips which are set in sealing and anchoring engagement, respectively, with a surrounding well conduit by an hydraulic setting mechanism. The gravel pack apparatus cooperates with the set packer to form a series of separate, axially extending, flow passages which may be selectively opened or closed.

摘要： Disclosed is a retrievable, hydraulically set well packer which is locked in set position without need for tubing rotation and may be released from set position by shearing a retrieving link with either a straight pull on the production tubing or by the application of high pressure through the tubing. Dual, opposed cones are employed for retaining the packer slips anchored irrespective of the direction of the pressure differential acting on the packer and without need for an extra sleeve to transmit pressure induced forces to the cones. Compression seals are employed to hold the slips firmly anchored against longitudinal displacement in both directions without reliance on the presence of a pressure differential across the set packer. The seals are employed as two separate assemblies which are positioned above and below the slips to isolate a portion of the pressure induced forces from the retrieving link. A modified form of the invention employs the dual cone, dual seal design on a packer having multiple flow passages.

摘要： Disclosed is a rig for working on wells, and including a pair of continuous chains for moving a pair of pipe holders along a mast. Each of the two pipe holders is fixed to a point in each chain. The chains are driven along parallel paths by twin motors with linked drive shafts. The motors are mounted on the top of the mast so that only one side of the closed loop on each chain is loaded when the pipe is being pulled from a well. One of the pipe holders may comprise a snubbing head which may be operated in reciprocal motion for high speed snubbing of pipe into a well.
