  • Publication number: 20190249208
    Abstract: The present invention relates to variant thioesterases and their use in plants, e.g., to increase enzymatic activity and to promote increased production of mid-chain length fatty acids (e.g., 8 to 14 carbons) and at desired ratios. Further disclosed herein are methods of manufacturing renewable chemicals through the manufacture of novel triglyceride oils followed by chemical modification of the oils. Oils containing fatty acid chain lengths of C8, C10, C12 or C14 are also disclosed and are useful as feedstocks in the methods described herein.

  • Patent number: 10316299
    Abstract: The present invention relates to beta-ketoacyl ACP synthase genes of the KASI/KASIV type and proteins encoded by these genes. The genes can be included in nucleic acid constructs, vectors or host cells. Expression of the gene products can alter the fatty acid profile of host cells. The KAS genes can be combined with a FATA or FATB thioesterase gene to create a cell that produces an increased amount of C8-C16 fatty acids. Suitable host cells include plastidic cells of plants or microalgae. Oleaginous microalga host cells with the new genes are disclosed.

  • Patent number: 9873617
    Abstract: A method for producing a sulphided copper sorbent includes the steps of: (i) contacting a sorbent precursor material containing one or more sulphidable copper compounds, with a sulphiding gas stream including hydrogen sulphide to form a sulphided sulphur-containing sorbent material, and (ii) subjecting the sulphided sulphur-containing sorbent material to a heating step in which it is heated to a temperature above that used in the sulphiding step and ?110° C., under an inert gas selected from nitrogen, argon, helium, carbon dioxide, methane, and mixtures thereof, the inert gas optionally including hydrogen sulphide. The method provides sulphided copper sorbents that have reduced levels of elemental sulphur.

  • Patent number: 9829156
    Abstract: An integrated cryogenic fluid delivery system includes a cryogenic liquid tank having an interior, a wall and a geometry. The interior of the cryogenic liquid tank contains a supply of cryogenic liquid. A fuel pickup line is positioned within the interior of the tank and is in fluid communication with a vaporizer so that the vaporizer receives and vaporizes cryogenic liquid from the tank. The vaporizer is positioned outside of the tank and is secured to the wall. The vaporizer also has a shape that conforms with the geometry of the tank.

  • Patent number: 9783972
    Abstract: A cistern comprises an upper water tank as a first chamber, and a lower water tank as a second chamber connected by an opening. At the top of the upper tank a mains water inlet allows mains water into the tank through an inlet valve, which is under the control of an upper float. An auxiliary water inlet allows water from an auxiliary supply, such as condensate from an air-conditioning unit, into the tank. At the bottom of lower tank is an water outlet, which allows flushing water from the lower tank 104 to flush an appliance (not shown) under the control of an outlet valve. The outlet valve is under the control of an actuator, which is configured to move up and down, and is also under the control of a lower float.

  • Publication number: 20170274136
    Abstract: A weighing system for medical applications may include a basin that has a base and a sloped sidewall that collectively form a bounded cavity with open top surface that receives and holds the material to be weighed. The basin may be free floating above the weighing device within a restricted range of travel. In some examples, the weighing system includes a thermal treatment device to adjust the temperature of the material in the basin. The rate at which heat is delivered to the basin may vary depending on the weight of the contents in the basin.
