Abstract: A process for the verification and validation testing of equipment and components for drilling, completion, production and general well construction (typically such as subsurface safety valves, wellhead trees, blowout preventers and wireline pressure control equipment) to determine the suitability of such equipment for use in oil and gas wells in high pressure high temperature environments. In particular, the process of the present invention comprises, among other steps, the steps of analyzing such components using an elastic-plastic finite element model with respect to certain preset load conditions and establishing stable model convergence, conducting a ratcheting assessment by running analysis on such model on all components that exhibit local plasticity, and examining all components to determine fatigue sensitive locations and subjecting such components to a fatigue analysis.

Abstract: The present invention discloses a method and system for providing defect management of a bulk data storage media wherein logical addresses of media data blocks are continuously slipped to omit all media data blocks determined to be defective at the time of an initial media format. Thereafter, selectable parameters are utilized to define a logical zone including both a user data area and corresponding replacement data area on the media such that proper selection of the parameters provides defect management optimized for a particular use of the media.

Abstract: A system and method for providing protection of content stored on a bulk storage media is disclosed. The technique for providing protection from unauthorized utilization of the content so stored is provided publicly in order to allow for those utilizing a conforming media device to master or generate content protected according to the present invention. Various ways in which to protect content are disclosed including verification of the authenticity of a particular media, utilization of an accepted list of media play-back devices and their corresponding published public keys in order to securely pass media content keys thereto, and utilization of an external contact to provide media content keys and/or updates of accepted media play-back devices.

Abstract: An improvement in a reciprocating engine used in an energy recovery system wherein the inlet valves to the cylinders of the engine are operated by independently time adjustable actuating means.The system for recovering energy from a pressured reactor comprising a reactor, a reciprocating engine connected to the reactor to receive reaction effluent from said reactor thereby driving the pistons of the reciprocating engine by expansion of the effluent and recovery apparatus downstream of the engine for recovering products from the effluent.The expanding reactor effluent is used to drive the pistons which are especially valved in conjunction with the effluent inlet port in the cylinder to facilitate handling the effluents to adjust the flow into an expansion chamber to obtain maximum recovery, the pistons in turn operate a crankshaft through a crosshead which may power compressors or operate a generator to produce electricity.
