20090028700 | APPLIANCE PUMP - A pump for washing appliance is described. The pump has a pump casing in which an impeller is located. The pump casing has an inlet and outlet, and an inlet conduit extending from the inlet at a small angle above the horizontal. The ceiling includes a downwardly extending dividing wall section extending radially from a central location to a side wall of the casing. The dividing wall is positioned between the inlet outlet. The ceiling incorporates a ramped surface rising around the central location, between the outlet side and the inlet side of the dividing wall. The ramped surface is higher adjacent the inlet side than the outlet side of the dividing wall section so that when the impeller is not rotating, air inside the pump chamber will rise up the ramped surface through the inlet and up the inlet conduit. | 01-29-2009 |

20090110553 | Omnidirectional electric fan and fan blade structure - The present invention discloses an omnidirectional electric fan and a fan blade structure. The fan blade structure comprises: a transmission shaft, a lower connection element, an upper connection element and a plurality of fan blades. The fan blades are radiately secured in between said lower connection element and said upper connection element. Each fan blade has a root portion and a wing portion. The wing portion extends from the edge of the root portion toward both sides to form a wider portion at the border of the fan blade. The fan blade structure cooperates with a seat, a cover, a plurality of fan grills and a dynamic source to from an omnidirectional electric fan. | 04-30-2009 |
20130115074 | TURBO MOLECULAR PUMP DEVICE - A control unit, which is integrally mounted on a turbo molecular pump, is provided, in which the control unit can be miniaturized or the manufacturing costs are reduced. An upper casing ( | 05-09-2013 |
20140271172 | FREE-TIPPED AXIAL FAN ASSEMBLY - A free-tipped axial fan assembly includes a fan having a blade tip geometry which minimizes the adverse effect of a tip gap. The maximum blade thickness exhibits a significant increase adjacent the blade tip. In some constructions, the maximum thickness at the blade tip is at least 100 percent greater than the maximum thickness 0.10R away from the blade tip. In some constructions, the trailing-edge thickness at the blade tip is approximately the same as the trailing-edge thickness 0.10R away from the blade tip. In some constructions, the increase in blade thickness follows the square of the distance from the position where the increase begins. | 09-18-2014 |
20150023789 | Wind Turbine Power Augmentation - Wind power generator. The generator includes a wind turbine rotating in an aerodynamically contoured duct and capable of generating increased power by increasing the wind flow at the turbine. A wind turbine is located at the entrance to a diverging duct. The duct expands in the wind direction following the wind turbine section, increasing the flow. A porous disk is located at the trailing edge of the aerodynamically contoured duct and this disk reduces die pressure at the trailing edge of the duct thereby sharply accelerating the flow through the duct and increasing die power output of die wind turbine. The porosity of the disk can be geometrically modified such dial the flow field changes to respond to changing wind conditions. | 01-22-2015 |
20160061046 | Turbine Vane With Non-Uniform Wall Thickness - A vane for use in a gas turbine engine has an airfoil extending between a leading edge and a trailing edge, and is generally hollow. The vane has a radially outer platform and a radially inner platform. At least one of the radially inner and radially outer platforms has thicker portions circumferentially located beyond one of the leading edge and the trailing edge, and thinner portions circumferentially beyond circumferential edges of the airfoil. A mid-turbine frame and a gas turbine engine are also disclosed. | 03-03-2016 |
