  • Patent number: 12286596
    Abstract: Implementations of the disclosed subject matter provide a process for upgrading refinery residue feedstock. Step a) may include introducing the refinery residue feedstock into a fluidized bed reactor as a solid. In step b), the refinery residue feedstock may be heated to a devolatilizing and thermal cracking temperature in the fluidized bed reactor to produce a product stream comprising gaseous hydrocarbons and solid coke. The gaseous hydrocarbons may be subjected to catalytic hydroprocessing, in step c), in the presence of molecular hydrogen to increase the hydrogen to carbon ratio and lower the average molecular weight of the gaseous hydrocarbons. In step d), the gaseous hydrocarbons may be separated from the solid coke. In step e), the gaseous hydrocarbons from step d) may be subjected to further processing to produce at least one of: C1-C3 hydrocarbons, liquefied petroleum gas, naphtha range hydrocarbons, and middle distillate range hydrocarbons.

  • Publication number: 20130237610
    Abstract: Sympathovagal balance is essential in maintaining internal homeostasis. Imbalance in this can lead to many disease conditions such as cardiovascular diseases, type 2 diabetes mellitus, high blood pressure, gastroesophageal reflux disease (GERD), IBS, depression, COPD, etc. Sudden cardiac death and Myocardial infarction are result of autonomic dysfunction. Many drugs have been proposed for these conditions but lack in correcting the condition and can themselves produce side effects, such as prolongation of QT interval. Inventors of current invention observed serendipitously that vitamin MK-7 can restore the sympathovagal balance and also have cardio protective effect by shortening of QT interval and prolongation of RR interval. Further to this, it was also observed that vitamin MK-7 improves cardiac output, left ventricular work, HDL cholesterol and reduces blood sugar.

  • Publication number: 20110051139
    Abstract: A device for non-invasively measuring concentration of one or more analytes in a living subject or a biological sample, wherein the device includes several light sources, a system for controlling the timing and intensity of the light source outputs, a system for passing the light through the subject or sample, a system for measuring the amount of light transmitted, and a system for relating the measurement to the concentration of the analyte in question. The light sources are narrow band sources at different wavelengths, and are capable of being rapidly switched between two levels of intensity. The actual number of light sources required and the wavelengths of the sources are dependent upon the specific analyte being measured.
