  • Publication number: 20190088957
    Abstract: A fluid flow plate for an electrochemical fuel cell assembly comprises a first plurality of fluid flow channels extending across an area of the flow plate to define a flow field of the fluid flow plate. An array of first fluid transfer points is disposed along an edge of the flow field for communicating fluid into or out of the fluid flow channels. A gallery has a first peripheral edge portion bounded by the array of first fluid transfer points and at least two second peripheral edge portions each bounded by an array of second fluid transfer points disposed along fluid access edges of the fluid flow plate. The at least two second peripheral edge portions are disposed at oblique angles to the first peripheral edge portion such that the total length of the any of second fluid transfer points is at least as long as, and preferably longer than, the length of the array of first fluid transfer points.

  • Publication number: 20190075904
    Abstract: A hand held appliance, such as a hairdryer, includes a body, a duct, a fluid flow path extending through the duct from a first fluid inlet of the appliance to a first fluid outlet of the appliance. A primary fluid flow path extends from a second fluid inlet through which a primary fluid flow enters the appliance to a second fluid outlet. A fan unit is located in the primary fluid flow path for drawing fluid through the second fluid inlet. A filter is located in the primary fluid flow path. Fluid is drawn through the fluid flow path by fluid emitted from the second fluid outlet. A heater is provided in the body and extends at least partially along and around the duct.

  • Patent number: 10220171
    Abstract: An interface for positive pressure therapy includes a mask assembly, a headgear assembly and a connection port assembly. The mask assembly comprises a seal member that has an upper portion movably connected to an integrated lower portion, wherein the upper portion rolls during hinging movement of the upper portion relative to the lower portion. The headgear assembly allows connection to the mask assembly in a direction substantially normal to a direction of strap tension. The connection port assembly includes a swivel elbow with a valve member that controls flow through a port that opens toward the user.

  • Patent number: 10221860
    Abstract: A bladeless fan assembly for creating an air current includes a nozzle mounted on a base. The nozzle comprises an interior passage and a mouth for receiving the air flow from the interior passage and through which the air flow is emitted from the fan assembly. The nozzle defines an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The nozzle is detachable from the base, which is preferably sized to be accommodated within the opening of the nozzle for transportation.

  • Patent number: 10209185
    Abstract: Blood separation systems and methods are provided for controlling the interface between separated blood components. The system includes a centrifuge assembly having a light-transmissive portion, a light reflector, and a fluid processing region therebetween. An optical sensor system emits a scanning light beam along a path toward the light-transmissive portion, which transmits at least a portion of the scanning light beam to the fluid processing region and the light reflector. The light reflector reflects at least a portion of the scanning light beam toward the optical sensor system along a path substantially coaxial to the path of the scanning light beam from the optical sensor system toward the light-transmissive portion of the centrifuge assembly. The scanning light beam may be a white light beam or narrow spectrum beam. The reflected beam may be directed through the optical sensor system via optical fibers.

  • Patent number: 10181604
    Abstract: A bipolar fluid flow plate for an electrochemical assembly comprises a plurality of first fluid flow channels extending across a face of the flow plate to define a first fluid flow field of the fluid flow plate and a plurality of second fluid flow channels extending across a face of the flow plate to define a second fluid flow field of the fluid flow plate. The pluralities of first fluid flow channels and second fluid flow channels both occupying a common channel plane. An array of first fluid transfer points is disposed along an edge of the first fluid flow field for communicating fluid into or out of the first fluid flow channels. An array of second fluid transfer points is disposed along an edge of the second fluid flow field for communicating fluid into or out of the second fluid flow channels.
