  • Publication number: 20190227011
    Abstract: A method for measuring the content of sterol and/or derivatives thereof by utilizing nuclear magnetic resonance technology. A nuclear magnetic resonance internal standard method is used, and a specific quantitative peak of sterol and/or derivatives thereof is selected, to accurately measure the (total) content of the sterol and/or derivatives thereof. The method can accurately measure the content of sterol and/or derivatives thereof in extracts of animals, plants and/or microorganisms, food, medicines or cosmetics.

  • Publication number: 20170110279
    Abstract: Exemplary embodiments of the present invention are directed to a circuit protection device, A circuit protection device may comprise a housing defining a cavity and a metal oxide varistor (MOV) disposed within the cavity. The circuit protection device may further comprise a first terminal electrically attached at a first end to the MOV by solder and extending outside of the housing at a second end. An arc shield is disposed within the housing between the first end of the first terminal and at least partially over the solder. The circuit protection device may further comprise a spring configured to bias the arc shield against a micro switch having an indicator portion disposed at least partially outside of the housing.

  • Patent number: 9570260
    Abstract: A circuit protection device including a housing, a metal oxide varistor disposed within said housing, a terminal having a contact lead at a first end electrically attached to said metal oxide varistor by solder and having a second end extending outside of said housing, an arc shield disposed within said housing between said contact lead and said metal oxide varistor, a micro switch housed in a pocket portion of the housing, said micro switch having a trigger portion and an indicator portion disposed at least partially outside of said housing, said arc shield positioned against said trigger portion, and a spring configured to bias said arc shield away from said pocket portion and to move said arc shield away from said trigger portion when said solder is melted to provide a barrier between said metal oxide varistor and said contact lead, whereby the indicator portion is retracted into the housing.

  • Patent number: 7598107
    Abstract: A patterned structure forms a portion of the mold for a diamond molded structure but is separable from the mold by the same processes that release the diamond part. The mold portion may itself be a component in a MEMS or NEMS structure or device or the precursor to such a structure or device. The mold portion may be made from sapphire or silicon carbide. The mold portion may be coated and polished to obtain an optically smooth surface over the diamond mold inside pit. The coating may be formed from one or more of silicon carbide, PTFE, silicon nitride, silicon dioxide, sapphire, a metal, a plastic, and an epoxy.
