Abstract: A vehicle mounted chair assembly includes a grille guard that is mountable to a front end of a vehicle. A back rest is integrated into the grille guard such that the back rest extends upwardly in front of the series of members of the grille guard. A chair is pivotally coupled to the back rest. The chair is positionable in a deployed position having the chair lying on a horizontal plane to have an occupant is seated on the chair. Conversely, the chair is positionable in a stored position having the chair resting against the back rest.

Abstract: The invention relates to a free-radical initiator composition for polyolefin modification comprising a peroxide-modified inorganic solid particle prepared from: i) a liquid or solution of hydrogen peroxide, and ii) one or more inorganic solid particles, wherein the inorganic solid particles have affinity to the hydrogen peroxide through hydrogen bonding. The invention also relates to a method for preparing a peroxide-modified inorganic composition, comprising mixing a liquid or solution of hydrogen peroxide and one or more inorganic solid particles to form a suspension or gel, and optionally, filtering the suspension or gel and drying the filtered materials to form a solid, peroxide-modified inorganic composition.

Abstract: The invention relates to a process for modifying an olefin polymer composition comprising melt mixing an olefin polymer composition with a free-radical initiator composition comprising a peroxide-modified inorganic composition prepared from: i) a liquid or an aqueous hydrogen peroxide, and ii) one or more inorganic solid particles, wherein the inorganic solid particles have affinity to the hydrogen peroxide through hydrogen bonding. The invention also relates to a modified olefin polymer composition prepared by the process and various articles formed from the modified olefin polymer composition.

Abstract: This invention relates to a process for modifying an olefin polymer composition, comprising melt mixing an olefin polymer composition with a free-radical initiator composition comprising a metal peroxide powder, wherein the free-radical initiator composition initiates a free-radical reaction of the olefin polymer composition to produce a modified olefin polymer composition. The invention also relates to a modified olefin polymer composition prepared by the process and various articles formed from the modified olefin polymer composition.

Abstract: A casing shoe having a composite body portion, a coupling portion attached to one end of the body portion, and a one-way check valve assembly positioned in the body portion, the valve assembly and body portion having a centerline nozzle and a plurality of circumferentially spaced smaller diameter nozzles positioned around the centerline nozzle.

Abstract: An oscillating mud motor having a valve section and a piston section positioned within a hollow cylindrical housing wherein the valve section comprises a timing cycle valve and a spool valve which hydraulically controls rotational movement of a piston on a central shaft in the piston section for linear reciprocation within the housing.

Abstract: A casing centralizer having a multiplicity of support fingers positioned on a body of the casing centralizer each finger formed into a collapsible spring configured to support a predetermined load at an apex of the finger, each finger having a leading forward angle positioned downhole and a following aft angle positioned uphold and a landing tab positioned on an end of the finger adjacent the aft angle, the body includes a finger pocket which guides the landing tab with the finger collapses due to side loads.

Abstract: A buoyancy module assembly reduces the effective weight of a sub-sea conduit used in a deep-water wellbore drilling installation. The assembly includes a buoyant sleeve positioned around the conduit between upper and lower stop collar assemblies. The sleeve contains buoyant material forming most of its cross-section, with cross sectional segments thereof each encapsulated in a non-porous resinous material that forms an outer jacket around each segment. In one embodiment, a non-rotating generally circular inside diameter of the sleeve is formed by the thin layer of jacket material bonded directly to an interior reinforcing cage. A narrow gap is formed between the ID of the non-rotating sleeve and the OD of the conduit. The collar assemblies comprise an inner collar rigidly affixed to the conduit and contained within a larger diameter outer shell adapted for rotation relative to the fixed inner collar.

Abstract: A flexible wellbore casing guide having a tubular body positioned at an end of a wellbore casing having a lower stiffness than the wellbore casing whereby the casing guide more easily deflects as the wellbore casing is inserted into the wellbore without causing undue stress on a wellbore formation.

Abstract: A computer system generates medical messages based on an analysis of medical information associated with healthcare providers. The analyzed medical information may be derived from medical records and/or insurance claims, such as those that may be managed by a clearing house entity that manages the processing of medical insurance claims. Healthcare providers having certain patients that meet various analysis criteria may be identified for purposes of generating the messages that can serve to inform the health care providers about potential medical treatments and procedures, such as new drugs, that be significant for the health care provider and may also be significant to the patients of the health care provider who may be identified in the messages.
