  • Patent number: 12285587
    Abstract: A multi-fluid injector system and methods of operation thereof are presented. One embodiment of such a fluid injector system includes an automatic refill procedure for a fluid injector system comprising a fluid injector and an operably engaged syringe. The procedure includes the step of determining, using an electronic control device operably controlling the fluid injector system, whether a fluid injection procedure involving the syringe is impending. If the electronic control device determines that the fluid injection procedure is not impending, such that the automatic refill will not interfere with the fluid injection procedure, an automatic refill of the syringe is initiated.

  • Publication number: 20240076241
    Abstract: The present invention provides a system for continuous production of sulfur polymer cement. The system may include a series of high shear mixers, such as twin screw mixers or compounding extruders, to which a sulfur-containing starting material is added at one end, followed by at least one stage at which a sulfur modifier is added. Micro-aggregate may be added at one or more stages. At the discharge end of the continuous system, an extrudate is produced, and a pelletizer may be used to form pellets of the polymerized sulfur and micro-aggregate material. The pelletizer may comprise a flowing cooled water system, e.g., underwater pelletizer. The formed pellets may then go through a dryer system and then to a dry storage collection system.

  • Patent number: 11021394
    Abstract: Fibers to be added to concrete to improve its properties are coated with an alkali-insoluble polymer, to provide adhesion of the fibers to the concrete. In a further improvement, nanoparticles are dispersed in an alkali-soluble polymer coating, and this is used to coat the fibers. When the fibers are mixed into the concrete mix, the nanoparticles are dispersed throughout the concrete, avoiding problems from agglomeration of the nanoparticles if simply added to the concrete mix.

  • Patent number: 9931041
    Abstract: A method of determining fractional flow reserve (FFR) in a blood vessel having stenosis includes injecting fluid into the blood vessel upstream of the stenosis using a power fluid injector, measuring pressure drop across the stenosis, and calculating FFR from measured pressure drop. The injected fluid may comprise a contrast medium. Further actions may include placing a pressure sensor proximal of the stenosis, injecting fluid into the blood vessel upstream of the stenosis using the power fluid injector, and measuring pressure in the blood vessel proximal of the stenosis. The pressure sensor may then be repositioned to a position distal of the stenosis, fluid may be reinjected into the blood vessel upstream of the stenosis using the power fluid injector, and pressure may be measured in the blood vessel distal of the stenosis.

  • Patent number: 9808571
    Abstract: A pressure sensor for use with a fluid delivery system having good sensitivity at low pressure, but also configured to remain in operating condition after being exposed to high pressures is disclosed herein. In one variation, the pressure sensor includes a fluid path set, a deformable element associated with the fluid path set and configured to deform in response to an external pressure, and a pressure transducer for monitoring deformation of the deformable element. In certain embodiments, the pressure sensor is configured to measure fluid pressure within the range of between about 0 mm Hg to about 300 mm Hg. However, the sensor pressure is also be configured to remain functional after being exposed to pressure in excess of about 60,000 mm Hg.

  • Patent number: 8613808
    Abstract: Metal aluminides are formed by an initial thermal deposition process which forms an intermediary material comprising elemental aluminum and another elemental metal, as well as an oxide of the other metal. The thermally formed intermediary material is subsequently heated to initiate an exothermic reaction which forms the metal aluminide material. The reaction may be initiated by localized or bulk heating of the intermediary material, and may involve reaction between the aluminum and elemental metal as well as a thermite reaction between the aluminum and the metal oxide. The resultant metal aluminide material may be substantially fully dense and may contain oxide strengthening precipitates such as aluminum oxide.
