  • Patent number: 10119366
    Abstract: An insulated electrical conductor (MI cable) may include an inner electrical conductor, an electrical insulator at least partially surrounding the electrical conductor, and an outer electrical conductor at least partially surrounding the electrical insulator. The insulated electrical conductor may have a substantially continuous length of at least about 100 m. The insulated electrical conductor may have an initial breakdown voltage, over a substantially continuous length of at least about 100 m, of at least about 60 volts per mil of the electrical insulator thickness (about 2400 volts per mm of the electrical insulator thickness) at about 1300° F. (about 700° C.) and about 60 Hz. The insulated electrical conductor may be capable of being coiled around a radius of about 100 times a diameter of the insulated electrical conductor. The outer electrical conductor may have a yield strength based on a 0.2% offset of about 100 kpsi.

  • Publication number: 20180130375
    Abstract: The present invention allows a language learning platform to calculate a user's overall language skill. This may be performed as a standalone test or before, during and/or after a language course. The language learning platform may perform a Pre-CAT process, a CAT process, a stage 2—fixed form process and a scoring and reporting process. The Pre-CAT process is designed to quickly get an initial estimate of the user's overall language skill. The CAT processes improves on the accuracy of the Pre-CAT process, preferably until the conditional standard error of measurement for the user's overall language skill is less than a predetermined number. The stage 2—fixed form process may use the user's overall language skill to select speaking, listening and writing assessment items of an appropriate difficulty for the user.

  • Publication number: 20170369798
    Abstract: An olefin or a slack wax of 10 to 100 carbon atoms is oxidized by mixing said wax with a salt of an alkaline earth metal in an amount to provide 0.001 to 0.03 weight percent of the alkaline earth metal, the anion of the salt comprising 4 to 36 carbon atoms; heating the mixture to 100 to 180° C.; and supplying to the heated mixture a molecular oxygen-containing gas. The oxidation is conducted in the substantial absence of manganese or cobalt compounds. The oxidized wax may be esterified by reaction with an alcohol.

  • Patent number: 9682197
    Abstract: Devices, systems, and methods for performing injections with lowered likelihood of infection include needles and other injection means with protective sleeves or sheaths. The protective sleeve can protect the needle before, during, or before and during an injection. The force needed to administer an injection or penetrate an insertion site using an injection device or system with a protective sleeve can be about the same to up to 50% more than the force needed for a system or device without a protective sleeve. The force needed to collapse the protective sleeve can be less than 100 gram-force. The material, the thickness, or both the material and the thickness of the protective sleeve may differ when comparing the portion of the sleeve near the needle tip and the portion near the base of the needle.

  • Patent number: 9198825
    Abstract: Medical devices with novel spark gap electrode designs, able to control manually or automatically the electrodes gap are provided. These devices are used to generate a shock wave created by the rapid expansion and collapse of a plasma bubble that is formed between two spark gap electrodes placed in a special liquid medium, when a high differential voltage (kV) is applied to the electrodes. The resulting shock wave impacts a reflector to direct the energy into the body of an animal or a human toward the desired treatment location. This electro-hydraulic principle to create acoustic shock waves as a method of treatment is in use in the medical (lithotripsy, orthopedic use, wound treatment, burns, post-operative treatment, pain treatment, diagnosis, skin and organ transplantation supporting devices, arteriosclerosis treatment), cosmetic (treatment of scars and cellulite) and veterinary (treatment of musculoskeletal disorders) fields.
