    摘要: A stuffing box for a polished rod used with a downhole pump uses injectable packing to provide a seal around the polished rod. The stuffing box has a chamber for receiving the packing. The chamber has an opening to allow the addition of packing to the chamber. The packing is maintained in a compacted condition by either injecting additional packing through the opening or adjusting the volume of the chamber.

    摘要: An improved system and method is provided for feature selection for text classification using subspace sampling. A text classifier generator may be provided for selecting a small set of features using subspace sampling from the corpus of training data to train a text classifier for using the small set of features for classification of texts. To select the small set of features, a subspace of features from the corpus of training data may be randomly sampled according to a probability distribution over the set of features where a probability may be assigned to each of the features that is proportional to the square of the Euclidean norms of the rows of left singular vectors of a matrix of the features representing the corpus of training texts. The small set of features may classify texts using only the relevant features among a very large number of training features.

    摘要: The guide has a barrel segment and a bushing segment. The barrel segment couples to the upper end of the pump barrel. The bushing segment has a bushing stop. The length of the guide is adjustable so as to vary the length of the bushing stop from the barrel. By varying the length of the guide, the travel of the plunger is adjusted to provide for a small compression chamber without the plunger contacting the barrel.

    摘要: A system for supporting individuals or objects is disclosed that can be used, e.g., as a bunk for sleeping upon within a vehicle, such as, e.g., a truck or commercial vehicle. The system preferably includes a support platform, a pivot mechanism, and at least one flowable-medium spring. The support platform is provided with an upper surface to support at least one individual or object within a vehicle. The pivot mechanism is connected to the support platform so as to pivot the support platform around a pivot axis to move between a stored position and a deployed position in which the support platform supports the at least one individual or object. The at least one flowable-medium spring is provided with a first end fixed relative to the vehicle and a second end fixed relative to the support platform at a location displaced from the pivot axis. Each of the at least one flowable-medium springs is arranged so as to impart an extension force that biases the support platform toward the deployed position and so as to impart an extension force that biases the support platform toward the stored position during at least portions of the movement of the support platform between the stored position and the deployed position.
