  • Patent number: 12243009
    Abstract: A pre-processing and fulfillment system and method are described. In some implementations, the method may include receiving an order containing a retail component and a pharmacy component, processing the order for the pharmacy component and the retail component, and generating a tracking token identifying the order and authorizing a party to receive a component of the order. The method may include transmitting fulfillment instructions to a fulfillment system based on processed information for the order, and transmitting the tracking token to a computing device of the authorized party. Some implementations may also include receiving a signal indicating receipt of the tracking token and an authorized transfer of the component, and updating a status of the order based on the received signal.

  • Patent number: 4648450
    Abstract: Underground coal gasification process containing a novel system of injection and production wells. Specifically, the injection well is positioned at an angle with respect to horizontal of less than the angle of repose of loose coal and char for the particular coal seam, and the production well is positioned at an angle with respect to horizontal of greater than the angle of repose but less than 90.degree.. This system protects the injection well during the process and places the production well in a position for maximum production while relieving it of certain tensile and shear stresses.

  • Patent number: 4431055
    Abstract: Depleted zones or channels in in situ retorts that bypass unretorted zones can be plugged selectively by contacting the depleted zones in the in situ oil shale retort with an aqueous liquid, substantially free of a formation plugging amount of a solute, to increase the resistance of the depleted zone or channel to the passage of retorting gases.

  • Patent number: 4344486
    Abstract: Disclosed is a method and apparatus for the enhanced recovery of liquid hydrocarbons from underground formations, said method comprising recovering a mixture comprising carbon dioxide and contaminants comprising hydrocarbon, hydrogen sulfide, or mixtures thereof, from an underground formation; combusting said mixture with an oxygen enriched gas to form a concentrated carbon dioxide stream; and injecting at least a portion of said concentrated carbon dioxide stream into an underground formation to enhance recovery of liquid hydrocarbon.

  • Patent number: 4189447
    Abstract: Optically active organic compounds are prepared starting from optically inactive reactants by means of an optically active agent which influences the course of the reaction. In particular optically active compounds having a "meso" type carbon atom undergo an intramolecular ring closure in the presence of an optically active agent to yield an optically active product having one additional ring. The present process is particularly useful in the preparation of optically active bicyclic diketones which are important intermediates in the total synthesis of steroids.

  • Patent number: 4178289
    Abstract: A process for the preparation of 6-chloro-.alpha.-methylcarbazole-2-acetic acid from 6-chloro-.alpha.-hydroxy-.alpha.-methylcarbazole-2-acetic acid and/or 6-chloro-.alpha.-methylene-2-carboxylic acid, is described. The preparation of intermediates, such as, 6-chloro-.alpha.-hydroxy-.alpha.-methylcarbazole-2-acetic acid and lower alkyl carbazole-2-oxalate, inter alia, is also described.

  • Patent number: 4055399
    Abstract: A method for tracing the flow of a plurality of fluid slugs injected into a subsurface formation using a number of tracers smaller than the number of fluid slugs. Single tracers are used in a number of fluid slugs equal to the number of tracers. In the remaining injected fluid slugs, combinations of at least two of the tracers in predetermined concentration ratios are used. Recovered fluid is analyzed for the presence of each of the tracers and the ratios of the tracers indicates breakthrough of each injected slug.
