Abstract: A method and apparatus for a system for use with a well bore tool that is adapted to decouple the weight of the drill string from the operation and utilizes instead hydraulic or pneumatic pressure to advance a drilling tool into a well bore. A force balancing system is attached between the drill string and the well bore tool by pressurizing a first and second chamber in the force balancing system. The weight of the drill string is then decoupled from the well bore tool and pressurization of the second chamber is subsequently reduced when the weight of the drill string begins to move into engagement with the well bore tool.

Abstract: Improved reactors for catalytic, exothermic gas phase reactions with, as seen in the flow direction of a feed gas, which contains at least one oxidant and at least one component to be oxidized, an entry zone (1), a reaction zone (2) comprising at least one catalyst (4) and an exit zone (3) for the product gas are described. The reactors, at least in the area of the entry zone (1), have means, for example insulating jackets (6) and/or devices for the transport of cooling agents, which decrease the transport of heat produced in the reaction zone (2) into the entry zone (1) and thus decrease the risks of pre-ignition of the feed gas mixture employed or of the course of undesired side reactions in the entry zone (1) and/or wherein the inner walls of the reactor, at least in the area of the entry zone (1), are elaborated from inert material. The feed gas enters into the entry zone (1) as a homogeneous gas mixture with respect to its substance composition via one or more feed lines (30). The reactors can especially be employed for ammonia oxidation, for example in nitric acid plants, in which transition metal catalysts preferably elaborated in honeycomb form with smaller cross sections than the customarily employed platinum gauzes are used.

Abstract: The present invention provides a method and apparatus for producing a treated hydrocarbon containing stream for use as a feed to a steam methane reformer of a hydrogen plant. In accordance with such method, amounts of olefins and organic sulfur species within an untreated feed are decreased in a reactor that is operated in either a hydrogenation mode to hydrogenate the olefins into saturated hydrocarbons or a pre-reforming mode in which hydrocarbon containing two or more carbon atoms including the olefins are reacted with oxygen and steam to form saturated hydrocarbons, methane, additional hydrogen and carbon monoxide. The reactor is configured and operates at a sufficiently high space velocity that olefin and organic species slip occurs that is further treated in a hydrotreater. The reactor contains a catalyst capable of promoting both hydrogenation and oxidation reactions and the hydrotreater contains a catalyst that is capable of only promoting hydrogenation reactions.

Abstract: An articulated seating system supports a user seat using a mounting assembly, a fore-aft slide assembly, a swivel assembly and an extension assembly driven by a drive packet having one or more motors or the like. The seat is moved from a secured drive position (e.g., a standard interior vehicle seat position) to an extension position (wherein the seat faces out of a vehicle doorway) and finally to an access position outside the vehicle, facilitating access for a user having limited mobility, strength, etc. Extendible supporting arms engage and enclose guide rollers to allow stable and precise control of lateral and vertical seat movement. Moving between the drive and extension positions, the seat can move through a narrow transition corridor in the motor vehicle. The motors can operate manually to allow securing the seat in the drive position despite power or other failure.
