  • Publication number: 20180264285
    Abstract: A breast cup system for improving breast health and anaerobic cell apoptosis includes a breast cup configured to vascularly isolate a breast from the body thereof via an onset of a tourniquet-like suction (TSO) applied to the breast. The suspension of vascular circulation in the breast enables a hyperthermic isolation therein via retaining indigenous heat or applied external heat. A microcontroller is configured to control the TSO and various thermic devices and electromagnetic radiation (EMR) applied to the breast via the breast cup to create the hyperthermic isolation sufficient to cause apoptosis of anaerobic cells therein. The system further includes a heat transfer detection of anaerobic cell apoptosis based on a ratio of an amount of heat transferred from the breast cup over a period of time through the breast relative to a heat transfer through a healthy breast tissue of a same mass over a same period of time.

  • Publication number: 20180052142
    Abstract: Element One has developed thin films have the ability to quickly, reliably and cost-effectively detect the presence of dissolved hydrogen in liquids through either a visible color change or a measurable resistance change. Thin film sensors are multi-layer thin film devices incorporating a substrate, an active transition metal oxide layer, a discontinuous catalyst layer, as necessary nn additional protective layer. This invention may be used for early detection of fault conditions in transformer oils allowing low cost tests that can effectively Such thin films can also detect the presence of dissolved hydrogen in aqueous solutions for certain therapeutic heath drinks and other applications.

  • Publication number: 20150136415
    Abstract: A buoyant ball assisted hydrostatic lift system and method comprises a second annulus formed between a well bore and an outer pipe within the well bore, and a first annulus formed between the outer pipe and an inner pipe. The system includes a seal disposed on the second annulus on at least a top end and a bottom end thereof with respect to the earth's surface. The seal is configured to prevent a fluid flow there through and preserve a condition of the well bore and the outer pipe and protect the environment against well perforations. The system also includes buoyant balls entrained in a first fluid in one of the annuli and an entrained column of the buoyant balls in the first fluid in one of the annuli, an aggregate weight thereof configured to entrain the balls and the first fluid into a second fluid in the inner pipe.

  • Patent number: 8936093
    Abstract: A hydrocarbon lift system and method for increasing petroleum production from an enclosed subterranean reservoir to the earth's surface comprises a column of buoyant balls in an outer pipe configured to entrain the buoyant balls into a first fluid in an annulus formed with an inner pipe drill string. A pressure differential in the inner pipe with respect to the reservoir via the entrained buoyant balls in a second fluid therein lifts the second fluid and the entrained balls via the inner pipe to increase petroleum production to the to earth's surface. A controlled rise velocity of the buoyant balls and the second fluid is predetermined by a ratio of a mass density of the buoyant balls to a mass density of the second fluid being greater than a mass density of the buoyant balls to a mass density of the first fluid for an increase over time in oil production.

  • Patent number: 8574917
    Abstract: Disclosed is a pigment that changes color upon exposure to hydrogen sulfide gas. The pigment may be ground or otherwise reduced to small particles and used in coatings, dyes, paints or inks. Potential applications for paints and inks include the production of warning indicators for the presence of hydrogen gas in areas where such presence may pose a hazard. Warning decals may be printed with pigmented ink and posted in areas of potential hydrogen hazard. In the presence of hydrogen sulfide gas, the decals can display a warning by causing a change in the color of a printed message. Objects may also be coated with pigmented paints so that if a hydrogen sulfide leak occurs from within or nearby the object, the color of the object changes to provide a warning of the presence of leaked hydrogen sulfide. Example applications of such painted objects include any industrial process containing hydrogen sulfide.

  • Patent number: 4535546
    Abstract: Locksmith tool apparatus determines the length of a locking element in a lock by engaging a locking element inside a lock and by moving the element to compress a compression spring to a known minimum length and by measuring the distance moved. By subtracting the distance the element is moved from known dimensions, the length of the locking element is determined.
