  • Fan assembly
    Patent number: 8348596
    Abstract: A fan assembly for creating an air current includes an air outlet mounted on a stand. The stand includes a base and a body tiltable relative to the base. The fan assembly has a center of gravity located so that when the base is located on a substantially horizontal support surface, the projection of the center of gravity on the support surface is within the footprint of the base when the body is in a fully tilted position.

  • Fan
    Patent number: 8348629
    Abstract: A bladeless fan assembly for creating an air current includes a nozzle mounted on a base housing a device for creating an air flow through the nozzle. The nozzle includes an interior passage for receiving the air flow from the base and a mouth through which the air flow is emitted. The nozzle extends about an axis to define an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The nozzle includes a surface over which the mouth is arranged to direct the air flow. The surface has a diffuser portion tapering away from the axis, and a guide portion downstream from the diffuser portion and angled thereto.

  • Drying apparatus
    Patent number: 8347521
    Abstract: A drying apparatus has a casing, a cavity formed in the casing for receiving an object, a fan located in the casing and creating an airflow, and at least one slot-like opening communicating with the fan and arranged in the casing so as to direct an airflow transversely across the cavity. The slot-like opening has a maximum width which is no greater than 0.8 mm. This produces a very narrow, high velocity, high pressure airflow which is capable of drying an object efficiently and quickly and is suitable for use in a hand dryer.

  • WATER MANAGEMENT IN FUEL CELLS
    Publication number: 20120321972
    Abstract: An electrochemical fuel cell having an anode, an ion transfer membrane and a cathode has liquid water delivered to the fluid flow channels within the cathode so as to maintain a relative humidity of 100% throughout the fluid flow channels. A calibration method and apparatus is described for determining an optimum quantity or range of quantities of liquid water to be delivered to the cathode fluid flow channels under varying operating conditions. An operating method and apparatus is described that ensures an optimum quantity of liquid water is delivered to the cathode fluid flow channels under varying operating conditions.

  • SURFACE TREATING APPLIANCE
    Publication number: 20120284959
    Abstract: A surface treating appliance includes a first cyclonic separating unit including a plurality of first cyclones arranged in parallel about an axis, and a second cyclonic separating unit located downstream from the first cyclonic separating unit and including a plurality of second cyclones arranged in parallel. The plurality of second cyclones is divided into at least a first set of second cyclones arranged about the axis and a second set of second cyclones. Each of the first cyclones and the second cyclones has a longitudinal axis. The longitudinal axes of the first cyclones are arranged at a first orientation to said axis, the longitudinal axes of the first set of second cyclones are arranged at said first orientation to said axis, and the longitudinal axes of the second set of second cyclones are arranged at a second orientation, different from the first orientation, to said axis.
