  • Publication number: 20240066424
    Abstract: A chomping bubble producing toy including a shaft secured between a bubble solution reservoir and a housing. The housing is the shape of a character and includes an upper and moveable lower jaw piece. A lever is secured to a connection rod within the housing, which connection rod is secured to the lower jaw about a rotational axle. When the lever is pulled, the connection rod moves upward, which pushes the lower jaw down about the fixed rotational axle. A compression spring is secured to the connection rod, which spring keeps the jaw closed when the lever is at rest. Secured within the housing adjacent to the connection rod is a lever switch. When the lever is pulled, the connection rod moves and contacts the lever switch, thereby triggering it, which automatically plays sound from a speaker within the device and/or transmits a wireless signal.

  • Patent number: 10549143
    Abstract: A large muscle exercise machine utilizes resistance to increase the effectiveness for a plurality of exercises performed by the user. The large muscle exercise machine includes a base frame, a support platform, a telescoping handlebar support, a handlebar, a first handle, a second handle, a first compression-adjustment mechanism, and a second compression-adjustment mechanism. The support platform is slideably engaged along the base frame to allow the user to position the support platform along the base frame. The telescoping handlebar support supports the handlebar. The first handle is rotatably mounted to the handlebar through the first compression-adjustment mechanism. Similarly, the second handle is rotatably mounted to the handlebar through the second compression-adjustment mechanism. The first compression-adjustment mechanism allows the user to adjust the resistance to rotation for the first handle.

  • Patent number: 9874825
    Abstract: Processes for continuously coalescing particles from an aggregated particle slurry are disclosed. The aggregated particle slurry is heated, then coalesced by raising the pH. The coalesced particles are homogenized and exit as a coalesced particle slurry. A multi-screw extruder is used for the coalescing. These processes are useful for providing coalesced particles such as toner compositions.

  • Patent number: 9876437
    Abstract: An interleaved transformer or a transformer and integrated set of inductors formed via a magnetic structure comprising a set of E cores and an I core inserted between the set of E cores is provided in order to address issues that occur when a structured transformer is coupled together with inductor flux. Actual inductance exhibited by the transformers is controlled by a preselected precise gap between the I core and each of the E cores. The advantage of such a structured transformer cancels out the magnetic flux in certain legs of the magnetic structure requiring less magnetic material and thus, less core losses while improving the overall efficiency of a power supply.

  • Publication number: 20170183411
    Abstract: The present invention provides new systems and strategies for the regulation of iron metabolism in mammals. In particular, methods of using agonists and antagonists of TGF-? superfamily members to modulate the expression or activity of hepcidin, a key regulator of iron metabolism, are described. The inventive methods find applications in the treatment of diseases associated with iron overload, such as juvenile hemochromatosis and adult hemochromatosis, and in the treatment of diseases associated with iron deficiency, such as anemia of chronic disease and EPO resistant anemia in end-stage of renal disease. The present invention also relates to screening tools and methods for the development of novel drugs and therapies for treating iron metabolism disorders.

  • Patent number: 9090760
    Abstract: Processes for continuously producing latex emulsions are disclosed. A multi-screw extruder is used for the production of the emulsion. A resin is fed into the extruder, heated, optionally dissolved in a solvent, mixed with a base to neutralize the resin and form particles, then mixed with a surfactant and water to form a phase inverted emulsion (PIE). The PIE may be sent to a distillation column to separate out the solvent, and the resulting latex emulsion is then sent to a receiving tank. These processes are useful for making precursors for toner compositions.

  • Patent number: 9052625
    Abstract: A continuous process for making a pigment dispersion includes continuously feeding a pigment into a feed section of a screw extruder at a controlled rate, continuously feeding a surfactant into the feed section of the screw extruder at a controlled rate, continuously feeding water downstream of the feed section to emulsify the pigment and the surfactant, forming a water-in-pigment dispersion, continuously feeding additional water downstream of the previously fed water to cause a phase inversion of the water-in-pigment dispersion, forming a pigment-in-water dispersion, continuously homogenizing the pigment-in-water dispersion in the screw extruder to create a homogenous aqueous pigment dispersion and collecting the homogenous aqueous pigment dispersion from an exit section of the screw extruder.

  • Patent number: 8994211
    Abstract: According to one embodiment, a circuit for providing redundant power includes a first channel having a first input, a first electronic circuit breaker, and a first output, a second channel having a second input, a second electronic circuit breaker, and a second output, and a first transistor coupled to the first electronic circuit breaker, the first transistor in series with a second transistor coupled to the second channel. The circuit normally operates by providing power to the first and second outputs from the first and second channels, respectively. However, if the first channel fails, the transistors switch on to allow power from the second channel to feed the first output in the first channel in addition to feeding power to the second output, and vice versa. Other embodiments and methods for providing redundant power are described as well.
