  • Patent number: 10743459
    Abstract: A hand-held spreader is provided having a housing with a compartment for particulate material, a chamber below the compartment having a bottom wall with a circular aperture, an impeller mounted for rotation in the chamber along such bottom wall responsive to a hand crank, a discharge opening, and a path along which the particulate material passes into the chamber for discharge via the discharge opening. The impeller has an outer circular periphery proximal to and extending over an outer edge of the aperture to form a gap between the impeller and the bottom wall of the chamber that seals the gap from the particulate material larger than the gap from entering under the impeller and risking obstruction of impeller rotation. Any particulate material that enters the gap passes downward through the aperture to enable self-cleaning of particulate material that would otherwise collect under the impeller in the chamber.

  • Patent number: 10502054
    Abstract: A technique facilitates monitoring of a multiphase fluid flow. The fluid flow is directed through a choke valve comprising a choke actuation system which controls a flow rate of the fluid passing through the choke valve. The choke valve also comprises a velocity reduction area which is created by a choke gallery. The choke gallery reduces the velocity of the fluid flow to encourage separation of phases of the multiphase fluid. A sensor is positioned along the gallery at a desired region to monitor a property of at least one separated phase of the multiphase fluid. For example, the sensor may be positioned proximate a bottom of the choke gallery to monitor a property related to a water phase which separates and transitions to the bottom due to its greater density.

  • Patent number: 9822890
    Abstract: A major challenge for the general use of “lab-on-a-chip” (LOAC) systems and point-of-care (POC) devices has been the generally complex and need for sophisticated peripheral equipment, such that it is more difficult than anticipated to implement low cost, robust and portable LOAC/POC solutions. It would be beneficial for chemical, medical, healthcare, and environmental applications to provide designs for inexpensive LOAC/POC solutions compatible with miniaturization and mass production, and are potentially portable, using compact possibly hand-held instruments, using reusable or disposable detectors. Embodiments of the invention address improved circuit elements for self-powered self-regulating microfluidic circuits including programmable retention valves, programmable trigger valves, enhanced capillary pumps, and flow resonators.

  • Patent number: 9562624
    Abstract: There is provided a double closure orifice fitting having an orifice fitting body and a valve carrier sized to be installed within a valve cavity. The body of the valve carrier has an actuator surface on the bottom, retainer clip recesses formed in the first and second end, one or more spring members extending from the top, and a valve strip having retainer clips that is removably attached above the top of the valve carrier body and against the spring members by engaging the retainer clip recesses and the retainer clips such that the retainer clips are held in tension by the one or more spring members. The valve carrier is movable between an open position spaced laterally from the passageway and a sealed position such that the valve strip sealingly engages the valve cavity to seal the passageway by an actuator that engages the actuator surface.

  • Patent number: 9539401
    Abstract: A tracheal coupling for interfacing between a patient and a gases source, the connector comprising a patient port (33) for connecting to the trachea interface/insert, an outlet port (36), and inlet port (31) between patient port and outlet port for receiving a flow of gases from the gases flow source, the connector restricting expiratory flow in use to produce PEEP of at least 1 cm H2O when flow to the inlet port is 50 liters per minute. A system or method for supplying gases to a patient using the connector is also disclosed. Flow restriction is implemented using an orifice that can be adjustable, jetting or turbulence induced by a directed flow nozzle (30). PEEP can also be varied by flow control of gas source.
