20080242758 | RADIATION-CROSSLINKED POLYOLEFIN COMPOSITIONS - An article suitable for use as an insulating or coating material comprises a radiation-crosslinked composition comprising a polyethylene, a polypropylene and optionally an ethylene-propylene elastomer. The polyethylene component is selected from high density polyethylene (HDPE), medium density polyethylene (MDPE) and linear medium density polyethylene (LMDPE) and the polypropylene component is either a homopolymer or copolymer.

20110297316 | LOW TEMPERATURE METHOD AND SYSTEM FOR FORMING FIELD JOINTS ON UNDERSEA PIPELINES - A method for forming a field joints between sections of coated or insulated pipe which are to be welded together and incorporated into an undersea pipeline for carrying single or multi-phase fluids such as oil, gas and water. The method includes the application of a liquid epoxy layer which overlaps a lip of the factory-applied FBE coating protruding beyond a chamfered end of the factory-applied insulation layer, and which may be applied over the entire weld joint area. The liquid epoxy layer is partially cured by application of heat, and a layer of powdered adhesive is applied onto the partially cured liquid epoxy layer. The adhesive is subsequently sintered and activated by application of heat to its outer surface. The outer surfaces of the adhesive layer and the chamfers are then preheated and the thermal joint insulation is injection molded over the entire joint area. Throughout the entire method the temperature of the factory-applied FBE coating is maintained below its glass transition temperature so as to avoid weakening the bond between the FBE coating and the underlying steel pipe. The number and sequence of steps can be varied, depending at least partly on whether the liquid epoxy and adhesive layers are applied in a pipe coating facility or in the field. | 12-08-2011 |

The non-chlorinated polyolefin preferably comprises polyethylene or a copolymer thereof. Exposure of the composition to moisture causes the formation of intermolecular crosslinks between molecules of the non-chlorinated polyolefin. The compositions can be formed by blending the non-chlorinated polyolefin with a silanated non-chlorinated polyolefin or by silane-grafting a blend of the chlorinated polyolefin and the non-chlorinated polyolefin. | 05-24-2012 |

20100114911 | SYSTEMS, METHODS, AND SOFTWARE FOR CLASSIFYING TEXT FROM JUDICIAL OPINIONS AND OTHER DOCUMENTS - To reduce cost and improve accuracy, the inventors devised systems, methods, and software to aid classification of text, such as headnotes and other documents, to target classes in a target classification system. For example, one system computes composite scores based on: similarity of input text to text assigned to each of the target classes; similarity of non-target classes assigned to the input text and target classes; probability of a target class given a set of one or more non-target classes assigned to the input text; and/or probability of the input text given text assigned to the target classes. The exemplary system then evaluates the composite scores using class-specific decision criteria, such as thresholds, ultimately assigning or recommending assignment of the input text to one or more of the target classes. The exemplary system is particularly suitable for classification systems having thousands of classes. | 05-06-2010 |
20100125601 | SYSTEM, METHOD, AND SOFTWARE FOR IDENTIFYING HISTORICALLY RELATED LEGAL CASES - The American legal system, judges and lawyers are continually researching an ever-expanding body of past judicial opinions, or case law, for the ones most relevant to resolution of new disputes. To facilitate these searches, some companies collect and publish the judicial opinions of courts across the United States in both paper and electronic forms, with some of the cases containing references to prior cases from other courts that have previously ruled on all or part of the same dispute. Identifying the prior cases is problematic, because, for example, conventional computer text-matching not only suggests too many non-prior cases, but also misses too many actual prior cases. Accordingly, the present inventors devised systems, methods, and software that generally facilitate identification of one or more documents that are related to a given document, and particularly facilitate identification of prior cases for a given case. One specific embodiment retrieves prior-case candidates based on information extracted from an input case, and then uses a support vector machine to determine which of the prior-case candidates are most probably prior cases for the input case. | 05-20-2010 |
