  • Publication number: 20260146433
    Abstract: A toilet may include a base including a bowl, a rim disposed around a top of the bowl, and a seat rotatably coupled to the rim. The eat may include a top surface configured to support a user and a bottom surface opposite the top surface. In some examples, the top surface is disposed at an incline and the bottom surface is supported by the rim. In some example, a dampener including a softer material than the bowl and disposed within the bowl. In some examples, a bidet wand extends from the base and is configured to selectively change between a position for dispensing a flow of water for washing a user and a position for cleaning a surface of the bowl. In some examples, the toilet includes a floor connector including a channel formed by a first flange and a second flange.

  • Publication number: 20250243655
    Abstract: A toilet includes at least an engine and a shroud. The engine includes a rim having an annular member, a water outlet, a toilet bowl, a water channel configured to dispense water into the toilet bowl from the water outlet, and an upstream trapway passage. The shroud includes a downstream trapway passage united with both the upstream trapway passage and a trapway outlet. The upstream trapway passage is spaced apart from the downstream trapway passage when the water flows through the upstream trapway passage and the downstream trapway passage to the trapway outlet.

  • Publication number: 20200261788
    Abstract: A properties, building structures, and securities wealth-building strategy game is played by multiple players on a game board. The game board has spaces that depict a bank, a stock board, move tracker, a stock exchange, a parking lot property, and a building property. The players can purchase securities with currency. The value of the securities is determined by drawing from two decks of security cards, with each deck having a positive value and a negative value. The values are summed to determine an increase or decrease in the price for the securities. A parking lot property and a building property can be selectively purchased by players who land on the corresponding property space with currency. A building structure can be purchased by players to generate rental income.

  • Patent number: 9759113
    Abstract: An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. An electromagnet is positioned within the housing and includes a coil of wire positioned proximate the valve member such that the valve member moves between a seated position and an unseated position relative to an orifice in response to energizing the electromagnet. A connector coupled to the housing includes an inlet tube concentrically aligned with and surrounding a return tube. The inlet tube is adapted to receive pressurized reagent from a source of reagent. The return tube is adapted to return reagent to the source.

  • Patent number: 7292676
    Abstract: A radiograph system with an anode plate, a cathode plate, and a power source coupled to said anode plate and the cathode plate. At least two wires coupled between the anode plate and the cathode plate provide a configuration to form an X-pinch having a photon source size of less than five microns at energies above 2.5 keV. Material at the configuration forming the X-pinch vaporizes upon application of a suitable current to the wires forming a dense hot plasma and emitting a single x-ray pulse with sufficient photons having energies in the range of from about 2.5 keV to about 20 keV to provide a phase contrast image of an object in the path of the photons. Multiple simultaneous images may be formed of a plurality of objects. Suitable filters and x-ray detectors are provided.

  • Patent number: 6628079
    Abstract: A discharge lamp bulb includes a light transmissive envelope and at least one conductive fiber disposed on a wall of the envelope, where the fiber has a thickness of less than 100 microns. The lamp may be either electrodeless or may include internal electrodes. Suitable materials for the fiber(s) include but are not limited to carbon, silicon carbide, aluminum, tantalum, molybdenum, platinum, and tungsten. Silicon carbide whiskers and platinum coated silicon carbide fibers may also be used. The fiber(s) may be aligned with the electrical field, at least during starting. The lamp preferably further includes a protective material covering the fiber(s). For example the protective material may be a sol gel deposited silica coating. Noble gases inside the bulb at pressures in excess of 300 Torr can be reliably ignited at applied electric field strengths of less than 4×105 V/m. Over 2000 Torr xenon, krypton, and argon respectively achieve breakdown with an applied field of less than 3×105 V/m.

  • Patent number: 5847517
    Abstract: Ignition of an electrodeless lamp, energized by microwave or radio frequency energy, is achieved by disposing a ferroelectric igniter in the lamp envelope along with the fill material. The igniter responds to switching of its spontaneous ferroelectric polarization by emitting electrons that collide with the atoms of the fill material to discharge further electrons and ultimately provide emission of light. In the preferred embodiment, the microwave or radio frequency energy used to excite the fill material is applied to the ferroelectric igniter to cause switching of its spontaneous ferroelectric polarization. Another preferred feature is the securing of the igniter, in the form of a thin patch or wafer, to the inside surface of the lamp envelope in a generally perpendicular orientation to the electric field in the microwave excitation energy.
