  • Patent number: 11857588
    Abstract: Extracts obtained from the genus Hippophae or other plant sources or compositions produced by chemical or molecular biological techniques each having in common certain moieties in amounts effective when combined with reproductive cells to reduce the loss of function.
    Type: Grant
    Filed: March 19, 2018

    Inventors: Lisa A. Herickhoff, James A. Herickhoff
  • Patent number: 11746639
    Abstract: The invention discloses a method of solution mining trona by injecting an aqueous solvent into an underground cavity comprising trona to dissolve trona in the aqueous solution and removing the aqueous solution from the cavity at about the WTN triple point (the temperature at which solid phase wegscheiderite, trona, and nahcolite can co-exist in an aqueous solution). Alkaline values from the removed aqueous solution are recovered to produce a barren liquor. The method further includes either (i) treating the barren liquor to produce an aqueous solvent or (ii) treating injected aqueous solvent to reduce clogging at the trona dissolution surface caused by supersaturation of sodium bicarbonate, and precipitation of nahcolite and wegscheiderite as the aqueous solution in the cavity approaches saturation of both dissolved sodium bicarbonate and sodium carbonate.

  • Patent number: 11166455
    Abstract: Embodiments of the present invention may provide effective processing of materials through phase transitions with a mobile phase transition device which may have a frozen storage area and a thawing area and which can be used to thaw biological materials near a recipient of the materials. A mobile phase transition device may be automated so that the thawing of materials can precisely follow thawing protocols.

  • Patent number: 11028368
    Abstract: An improved cryopreservation process and substances can involve a cellular collection (1) in a cryopreservation fluid (4) that has been conditioned or treated (7) to enhance the cryopreservation process by adding (18) energy (19) such as in the surface energy of a substance in the cryopreservation fluid (4) prior to reducing energy for that same cryopreservation media for freezing. This can offer enhanced-post-cryogenic viability of the cryopreserved structures or a more optimum cooling curve (22) for a specific cell type.

  • Patent number: 9667366
    Abstract: Embodiments of the present invention may include systems and methods for monitoring a person's activities. A system may receive an input and may contact a designated party to ensure they are safe or perhaps even confirm they are at a specified location at a specified time. A system may also provide an escalation response in those circumstances where a primary contact is not reached or perhaps where it is directed by a primary contact. Further, a system may provide communications to a primary contact or a user including a plausible excuse for the primary contact to leave an agenda location.

  • Patent number: 9260918
    Abstract: Disclosed are methods for solution mining of evaporite minerals, such as trona, comprising drilling an access well and at least two lateral boreholes; injecting a fluid; circulating the fluid through the lateral boreholes with a controlled fluid flow; and collecting a pregnant solution. Also disclosed are methods of solution mining that include injecting an aqueous solution into an underground trona cavity at a temperature sufficient to maintain at least a portion of the solution in the cavity in the Wegscheiderite solid phase region; removing aqueous solution from the cavity; and recovering alkaline values from the removed aqueous solution. Also disclosed are methods of solution mining that include injecting an aqueous solution into an underground trona cavity; removing aqueous solution from the cavity, wherein the temperature of the removed aqueous solution is at about the TWA point temperature; and recovering alkaline values from the removed aqueous solution.
