  • Patent number: 8246550
    Abstract: A Comprehensive Integrated Testing Protocol (CITP) incorporates precise measurements of the dynamic and the static lung volumes and capacities at V30 for routine infant lung function testing. The static functional residual capacity (sFRC) in infants is measured after a short hyperventilation induces a post-hyperventilation apnea (PHA) that abolishes the infant's breathing strategies and creates a reliable volume landmark. A measurement of the sFRC is then obtained by inert gas washout; e.g., by measuring the volume of nitrogen expired after end-passive expiratory switching of the inspired gas from room air to 100% oxygen during the PHA. A true measurement of the total lung capacity (TLC) is obtained from the sum of (1) the passively exhaled gas volume from a Pao plateau of 30 cm H2O through a pneumotachometer (PNT) by integrating the flow signal to produce volume, which is the inspiratory capacity (IC), and (2) the sFRC.

  • Patent number: 7964026
    Abstract: A gasification system having a combustor vessel, an optional scrubber vessel, an optional fixer vessel, an optional cyclone vessel and an optional demister vessel. A wide variety of possibly moist solid or semi-solid carbonaceous fuels may be partially combusted in the combustor to generate a combustible gas and a mineral ash. An improved ash support and removal subsystem reduces clogging and other problems. The combustible gas is conveyed by optional heavy-duty blowers through the optional vessels to remove liquids and particulates and to undergo catalytic chemical reactions to provide a relatively clean, dry, highly-combustible hydrocarbon gas that captures a relatively high fraction of the potential heating value of the fuel. Internal gases, liquids and particulates from the vessels may be recycled inside the system to improve efficiency and prevent liquid waste. A portion of the internal liquids may also be extracted for other uses.

  • Patent number: 7850706
    Abstract: A catheterization system for forming dual sutureless anastomoses using two catheters connectable to one another. Once the fistula is healed, a dissolvable connection allows the catheters to separate one from the other and the separated pieces are extruded through normal bowel action. The two catheters may be connected in various ways. In one embodiment, a separate guide member may be used to pull a dissolvable suture through the first catheter. The suture is then attached to the second catheter and the suture may be used to pull the second catheter into contact with the first catheter so that the two catheters are closely connected by the suture. When the suture dissolves, the two catheters separate. In another embodiment, the first catheter has a section formed of a dissolvable mesh. The two catheters may be connected together by any of various types of connections. After a period of time, the mesh dissolves and allows the joined catheters to separate into two pieces.

  • Patent number: 7713549
    Abstract: A tablet for the controlled release of a pharmaceutically active ingredient. The tablet is in the form of coated DST's and MLDST's so that immediate release or time-delayed release can be achieved. Further, such extended release DST's and MLDST's may provide zero order or first order extended release kinetics depending on the excipients and types of pharmaceutically active ingredients in the tablet formulation. The time delay coating is made of high molecular weight water soluble polymers so that dose dumping can be minimized even when the hydrated surface of the DST and MLDST peels off. A second coating of low molecular weight water soluble polymer with a pharmaceutically active ingredient dispersed therein provides for pulsatile release.

  • Patent number: 7662292
    Abstract: Media for selectively removing radium ions from water where manganese oxide (DMO) has been dispersed in a cation ion exchange resin (gel or macroporous) to adsorb radium ions. The media is manufactured by precipitating a soluble manganese (II) salt such as manganous sulfate with a permanganate salt such as sodium permanganate inside a strong acid cation (SAC) to form a resin containing highly dispersed manganese oxides. The resin is then post treated with a reducing agent such as sodium metabisulfite (Na2S2O2) to prevent the leaching of soluble manganese from the resin. The reducing treatment ensures that soluble manganese species will be converted into an insoluble oxide form.

  • Patent number: 7593250
    Abstract: A ferroelectric nanostructure formed as a low dimensional nano-scale ferroelectric material having at least one vortex ring of polarization generating an ordered toroid moment switchable between multi-stable states. A stress-free ferroelectric nanodot under open-circuit-like electrical boundary conditions maintains such a vortex structure for their local dipoles when subject to a transverse inhomogeneous static electric field controlling the direction of the macroscopic toroidal moment. Stress is also capable of controlling the vortex's chirality, because of the electromechanical coupling that exists in ferroelectric nanodots.

  • Patent number: 7225813
    Abstract: Multiple rib fractures in trauma patients are associated with significant morbidity and mortality. Delayed morbidity for patients with rib fractures is often a result of hypoventilation leading to atelectasis, pneumonia and respiratory failure. Pain management was first recognized as an important factor in preventing complications in these patients. Later, management of the respiratory system became more widely recognized as a major factor in, patients' care. It is now known that patients with multiple rib fractures benefit most from adequate pain control, rapid mobilization, and meticulous respiratory care to prevent complications. A rib fracture score and protocol based on a synthesis of the existing literature is developed. The protocol is directed to decisions about rapid mobilization, respiratory support, and pain management interventions to decrease the length of patients' stay in intensive care units.

  • Patent number: 7223875
    Abstract: A process for the recovery of molybdenum catalyst from the epoxidation reaction product of olefins with organic hydroperoxides. The active form of the glycol-molybdate epoxidation catalyst is removed from the process stream with an anion ion exchange resin. The ion exchange resin can be either a weak base or strong base type. The preferred embodiment of the invention produces a concentrated epoxidation catalyst in the “ammonium” form that is suitable for recycle to the catalyst preparation vessel. The ammonia form is converted into the active form by evaporating the water and ammonia from the recovered catalyst in the presence of a glycol. The preferred configuration of the ion exchange process is a “Lead-Lag” system. Two vessels will be in service while the third is in the regeneration mode recovering the epoxidation catalyst. A fourth polishing vessel can also be included as a “guard bed” to prevent leakage of the molybdate catalyst into the process stream.

  • Patent number: 7051506
    Abstract: A tire cord having core filaments (10) performed into a helical configuration while maintaining the core filaments (10) in a parallel, side-by-side relationship. The core filaments (10) are not twisted or stranded together. High tensile strength sheath filaments (11) are also performed into a flattened helical configuration so that the sheath filaments (11) can be wrapped around the side-by-side core filaments such that the sheath filaments (11) do not put such tension on the core filaments (10) as to cause the core filaments (10) to bunch. The core filaments (10) are maintained in a flat side-by-side configuration so that no voids are formed and rubber can penetrate into the tire cord. The core filaments (10) may number from three to six and the sheath filaments (11) from one to seven. The cross-section of the tire cord is flattened and confined within an oval-shaped outer bound (21), the oval outer bound (21) being characterized by a major axis and a minor axis.
