Abstract: A database system is operable to assign a first node as a task monitoring node for a task and assign a second node as a task execution node for the task. The task is executed via the first node and the second node based on the first node sending a plurality of polls to the second node, the second node initiating execution of the task based on one of the plurality of polls, the second node sending a plurality of task status data to the first node, the first node maintaining current task status data for the task a shared metadata state based on the plurality of task status data, the second node completing execution of the task and caching task results in memory resources, the first node receiving the task results from the second node; and the second node removing the task results from the memory resources.

Abstract: A database system includes a plurality of computing devices. Each computing device includes a plurality of processing modules, a computing device operating system, and an application specific operating system. The computing device operating system includes a computing device operating system file system management instruction set. The application specific operating system includes at least one custom file system management instruction set operable to configure operation of a configurable set of processing modules of the plurality of processing modules based on generating a corresponding file system management configuration signal for each processing module of the configurable set of processing modules indicating a selected file system management instruction set of the computing device operating system or the application specific operating system.

Abstract: A node of a computing system includes a main memory and a plurality of processing core resources that each can adjust a power level. The main memory includes a computing device section and a database section. The computing device section includes a computing device operating system area and a computing device general area. The database section includes a database section that includes a database operating system area, a disk area, a network area, and a database general area. The database operating system area allocates at least one portion of the main memory for database operations that is locked from access by the computing device operating system area.

Abstract: The invention relates to an efficient process for the preparation of isoolefin polymers such as polyisobutene or butyl rubber by polymerization of a liquid medium comprising the monomer(s) and ethane or carbon dioxide that is substantially dissolved therein.

Abstract: A turbofan engine having a thrust reverser having at least one movable control surface, movable to and from a reversing position where at least a portion of the bypass air flow is at least partially reversed, a thrust reverser actuation system having multiple actuators and a lockout mechanism movable between an inhibit condition, wherein movement of the multiple actuators is prevented, and a permit condition, wherein movement of the multiple actuators is permitted.

Abstract: Systems, methods, and non-transitory computer-readable media can generate at least one multi-author story using content items that satisfy one or more grouping criteria associated with the multi-author story, wherein the content items were previously published by users of a social networking system and provide access to the multi-author story to one or more users of the social networking system that satisfy one or more access restrictions associated with the multi-author story.

Abstract: An integrated process for the solution polymerization and subsequent halogenation of butyl rubber in a common medium is disclosed. The process comprises providing a solution polymerization reactor containing a C6 medium mixed with a monomer mixture comprising at least an isoolefin monomer and a multiolefin monomer in a mass ratio of monomer mixture to medium of from 61:39 to 80:20. Once polymerized, residual unreacted monomer mixture is separated from the rubber solution using a distillation process. The residual monomers may then be purified and recycled back into the reactor. The separated rubber solution is then halogenated. The process obviates the need for separating the rubber from the medium following polymerization, then re-dissolving it in another solvent for halogenation, thereby saving energy cost. The process optionally employs heat exchangers for the reactor feed streams to further reduce energy consumption.

Abstract: A portable water purifier for purifying a liquid to a safe form acceptable for drinking may be provided. The portable water purifier may include a container configured to hold the liquid, a filtering mechanism connected to the container configured to filter out dirt or sediment floc from the liquid, and a transport mechanism in communication with the filtering mechanism configured to transport the liquid into the filtering mechanism. The portable water purifier may also include a mixer inside the container configured to disperse a chemical disinfectant or a flocculating agent tablet within a liquid, for instance water.

Abstract: A downhole tool includes a thru-tubing high expansion, elastomeric inflatable seal and a thru-tubing mechanical anchoring arrangement. A method for separating pressure in a wellbore including actuating a mechanical anchoring system of a thru-tubing downhole tool; inflating a high expansion inflatable elastomeric seal against the tubing subsequent to actuating said mechanical anchor.

Abstract: A through tubing downhole tool, such as a bridge plug is delivered on coiled tubing. The setting process entails an initial pressurization to anchor the tool and compress its sealing element. The remainder of the needed force for setting the tool can come from an upward pull on the coiled tubing. Should more force than can be delivered from a pull on the coiled tubing be required to finish the setting and releasing process from the downhole tool, a jar or impact tool can be incorporated to boost the applied uphole force that is delivered from the pull on the coiled tubing at the surface. Alternatively, a pressure amplifier can be fitted to the coiled tubing so that a smaller pressure applied to the coiled tubing at the surface can deliver the required force to set and release from the downhole tool.

Abstract: An operating device for an electrical and/or electronic apparatus is adapted to the operating behavior of a user. The apparatus has a plurality of operating states which can be chosen or set by way of the operating device. The selection and/or setting, by the user, of the operating states is stored in a memory. A number of how often a given user input is implemented is ascertained and, for the next selection and/or setting of an operating state, that one which is implemented most frequently is suggested. An operating device for carrying out the method has a memory for storage of the implemented selections and/or settings of operating states, a counter for ascertaining the number of how often a selection and/or a setting is implemented, a calculator for ascertaining the frequency of a selection and/or setting and a comparator for ascertaining the most frequently implemented selection and/or settings.

Abstract: A process for producing improved alkaline water includes filtering potable source water to remove selected particles and then purifying the filtered water. Selected alkaline minerals are added to the purified water, with the resulting mineralized water being then electrolyzed to produce streams of acidic water and alkaline water, the alkaline water having a pH within the range of 9-10, a TDS range of 22-240 ppm (parts per million) and alkalinity in the range of 12-216 ppm.
