Title: Method to deliver energy in a well system
Inventor: SMITH DAVID R
IPC: E21B23/03
Filed: 2005-12-09
Granted: 2014-09-02
Abstract: The disclosure relates to an apparatus for insertion of a conduit into a well system bore to introduce a reactant fluid over a subterranean catalyst to initiate decomposition of the reactant fluid which resultant energy release may be utilized to perform work or perform heating of the subterranean environment. The reaction may be further accelerated by the addition of a fuel down into the reaction chamber or blended with the reactant fluid at a surface location. Reaction products can be jetted from a reaction chamber orifice against the proximal surface of the well system bore which may be either a production zone for the purpose of stimulating production or against a casing to perforate the casing and expose the production zone adjacent such perforation. The energy released from said catalytic reaction and subsequent combustion of fuels may also be used for cutting, welding, powering pumps, compressors, turbines, generators, or to heat well system fluids, pipes, subterranean reservoir fluids, subterranean solids, and completion devices in the well system.

Abstract: The invention relates to a method for producing a bevel gear wheel, in particular for rudder propellers, the teeth of which have a macro geometry specific to the gear wheels, the teeth of which can be described by flank and profile lines, the flanks of which have a tooth flank micro topography and the bearing surface of which represents the contact region of the inter-meshing teeth. The crown of a tooth flank corresponds to the elevation of the tooth flank center with respect to the tooth flank edge, wherein the course of the height and width crowns of the flank surface is substantially shaped like a circular arc. By means of precise material removal, the micro topography of the tooth flank and thus the bearing surface is optimized, firstly in that the material removal is carried out such that the end relief on the tooth flank surface is reduced toward the tooth heel side and the tooth toe side, an area having a greater length and width comes into engagement on the flank and thus an enlarged bearing surface is present, and secondly in that the course of the crown of a tooth flank follows an approximately logarithmic, elliptical and/or an exponential curve shape, which runs through the point of contact, when the ease-off is viewed with no load, in a longitudinal section in the flank sectional surface and/or in a profile section in the profile sectional surface,.

Abstract: The vanous embodiments relate to peptide antagonists of yc-family cytokines, lnterleukin-2 (IL-2), lnterleukin-4 (IL-4), lnterieukin-7 (IL-7), lnterleukin-9 (IL-9), lnterteukin-15 (IL-15), and lnterteukin-21 (IL-21 ). The yc-cytokines are associated with important human diseases, such as leukemia, autoimmune diseases, collagen diseases, diabetes mellitus, skin diseases, degenerative neuronal diseases and graft-versus-host disease (GvHD). Thus, inhibitors of yc-cytokine activity are valuable therapeutic and cosmetic agents as well as research tools. Traditional approaches to inhibiting yc-cytokine activity involve raising neutralizing antibodies against each individual yc-cytokine family member/ receptor subunit. However, success has been limited and often multiple yc-cytokine family members co-operate to cause the disease state. Combinatorial use of neutralizing antibodies raised against each factor is impractical and poses an increased risk of adverse immune reactions. The present embodiments overcome these shortcomings by utilizing peptide antagonists based on the consensus yc-subunit binding site to inhibit yc-cytokine activity.

Abstract: Techniques are provided for selecting which videos to recommend to users by predicting the degree to which recommending each video will satisfy certain goals. To make the predictions, a trained machine learning engine is fed both collaborative filtering parameter values and content-based filtering parameter values. In the case of video-to-video recommendations, the collaborative filtering parameter values may be based on a video pair that includes a video in which a user has already demonstrated an interest. The machine learning engine generates a machine-learning score for each video. The machine learning scores are used as the basis for selecting which videos to recommend to a particular user.
