Abstract: Ligament repair. Some examples are directed to methods and related systems for calibration of optical equipment for use in a computer-guided endoscopic ligament repair, such as repair of an anterior cruciate ligament (ACL). Other examples are directed to methods and related systems verification of registration between three-dimensional bone models and bone visible through an endoscope during ligament repair. Yet still further examples are directed to intraoperative changes to the tunnel plans for ligament repair.

Abstract: It is the object of the present invention to provide a mobile platform that allows the execution of physical stimulation and rehabilitation exercises through augmented reality games, of simple preparation and configuration, adaptable to various spaces and operating conditions. For this purpose, the platform comprises a sensory unit (2) and a projection unit (5), which are controlled by a processing unit (4). All these units are integrated in a mobile base (9), to allow the displacement of the platform. This also comprises a rotating joint (7) and an articulated arm (8) to allow the projection of games on the floor or on the wall.

Abstract: Tank for electrical transformer comprising a bottom plate, two side panels and two end panels joined to contain an insulating fluid, and reinforcements joined to the exterior of said panels, wherein the two side panels and the two end panels are vertically curving convex panels, wherein the reinforcements comprise a plurality of arched vertical reinforcements distributed horizontally along each panel. The reinforcements may comprise a plurality of bracing horizontal reinforcements joined between said vertical reinforcements. The inner arching profile of the vertical reinforcements preferably matches the outer curving convex profile of the panels. The horizontal reinforcements are preferably planar. The horizontal reinforcements are preferably located at a horizontal plane in the vertical middle of the respective panel. The horizontal reinforcements are preferably located at a middle horizontal plane or at parallel horizontal planes distributed vertically.

Abstract: A process and apparatus for managing hydrogen sulfide in a refinery is provided. In the process, a hydrogen sulfide stream from said refinery is fed to a sulfur recovery unit to produce sulfur and a sulfur compound stream or to a thermal oxidizer. The sulfur compound stream and the hydrogen sulfide stream are then thermally oxidized to produce a sulfur oxide stream. The sulfur oxide stream is then reacted with an ammonia stream. In aspect, the product of the reaction can be a fertilizer. The ammonia stream can be obtained from stripping the hydrogen sulfide stream.

Abstract: A power generation process for use in a processing unit that includes the steps of: using a regenerator to produce a flue gas stream; removing catalyst particles from the flue gas stream; routing the flue gas stream to a combustor/expander unit after performing the step of removing catalyst particles; and using rotation of the turbine of the combustor/expander unit as a source of rotary power. Preferably, the combustor/expander unit includes a combustion chamber and a power recovery turbine housed within a single casing. In certain embodiments, the flue gas stream is routed between the regenerator and the combustor/expander without passing through a compressor.

Abstract: An electrical enclosure wherein an electrical component can be moved between various positions (e.g., connected, disconnected, test, etc.) without opening an enclosure door. The electrical enclosure supports a component for movement between a withdrawn position, a test position, and an inserted position. A handle is accessible by an operator from an exterior of the enclosure and is configured to move the component between the respective positions without having to open the enclosure. The handle is integral with the enclosure and thus an operator needs no special tool or other device to effect movement of the electrical component between its respective positions.

Abstract: Recycle of an extract stream containing a contaminant is used to improve recovery of hydrocarbons in a contaminant removal process. At least a portion of an extract stream is recycled to a contaminant extraction zone and contacted with rich ionic liquid. Contaminants in the recycle extract stream are transferred to the rich ionic liquid.

Abstract: Methods and apparatuses are provided for producing a xylene product from a lignin supply. A method includes depolymerizing the lignin supply to produce a lignin aromatic stream, and isomerizing the lignin aromatic stream to produce an isomerized lignin stream. The desired xylene isomer is extracted from the isomerized lignin stream.

Abstract: The process converts FCC olefins to heavier compounds. The heavier compounds are more easily separated from the unconverted paraffins. The heavier compounds can be recycled to an FCC unit or delivered to a separate FCC unit. Suitable conversion zones are oligomerization and aromatic alkylation zones.

Abstract: Embodiments of methods for the production of linear alkylbenzene and optionally biofuel from a natural oil are provided. A method comprises the step of deoxygenating the natural oils to form paraffins. A first portion of the paraffins is hydrocracked to form a first stream of normal and lightly branched paraffins in the C9 to C14 range and a second stream of isoparaffins. The first stream is dehydrogenated to provide mono-olefins. Then, benzene is alkylated with the mono-olefins under alkylation conditions to provide an alkylation effluent comprising alkylbenzenes and benzene. Thereafter, the alkylbenzenes are isolated to provide the alkylbenzene product. Optionally a second portion of the paraffins and the isoparaffins are processed to form biofuel.
