  • BIDIRECTIONAL GAS DISCHARGE TUBE
    Publication number: 20210217573
    Abstract: A bidirectional gas discharge tube (GDT) includes a discharge chamber, first and second cathodes, a gas disposed within the discharge chamber, and a control grid. The first and second cathodes are disposed within the discharge chamber and include first and second faces, respectively. The first face and the second face are plane-parallel. The gas is configured to insulate the first cathode from the second cathode. The control grid is disposed between the first and second cathodes within the discharge chamber. The control grid is configured to generate an electric field to initiate establishment of a conductive plasma between the first and second cathodes to close a conduction path extending between the first and second cathodes.

  • Liquid flow distribution system
    Patent number: 10995025
    Abstract: A liquid flow distribution system comprises a flow chamber and a rotor. The flow chamber has a flow chamber inlet, a flow chamber outlet and a chamber flow path extending from the flow chamber inlet to the flow chamber outlet. The flow chamber path is curved so as to generate a generally vortical flow in liquid passing through the chamber flow path. The rotor has a plurality of rotor blades rotatably mounted about a rotor axis. The rotor is mounted in proximity to the flow chamber outlet and positioned such that a flow of liquid exiting the flow chamber outlet impacts one or more of the rotor blades to rotationally drive the rotor. Rotational driving of the rotor in turn disperses liquid impacting the rotor blades.

  • Conduit with heating element
    Patent number: 10953184
    Abstract: A conduit for a breathing circuit includes a heater associated, at least in part, with a hydrophilic layer. The purpose of the heater is to evaporate any condensed liquid collecting in the conduit, which is first sucked up by the hydrophilic layer. The heated wick reduces the risk of collected water being passed to the patient and causing choking fits or discomfit. It is preferred that the heated wick lies freely in the conduit to settle at low points in the conduit where condensation may collect.
