| 20090123270 | Pump - The invention relates to a pump for pumping contaminated liquid including solid matter, comprising a pump housing provided with a rotatable impeller suspended in a drive shaft and having at least one vane, and an impeller seat, at least one part of the impeller and the impeller seat being movable in the axial direction in relation to each other. Furthermore, the impeller seat presents at least one groove in the top surface thereof. | 05-14-2009 |
| 20100296919 | FLUID DRIVE DEVICE - A torque converter includes a pump shell constituting an internal space for retaining ATF and capable of rotating about the rotation axis; a blade engaging with the pump shell; and an extension sleeve pressing the blade against the pump shell. The pump shell has a groove into which a tip portion of the blade is fit formed at its inner peripheral surface. In the state where the tip portion is fit into the groove, the extension sleeve presses the blade to fix the blade to the pump shell. The groove forms an acute angle θ with respect to a meridian of the shell passing through the groove. The groove extends in one direction, has one end opened and the other end closed, and has a width larger on the side of the one end than on the side of the other end. The groove has a portion smallest in width equal to the width of the tip portion. | 11-25-2010 |
| 20110280711 | FAN DEVICE HAVING SIMULTANEOUSLY FOLDABLE BLADES - A fan device having simultaneously foldable blades includes a rotatable driving unit. A plurality of supporting frames extend outwardly from the driving unit, each supporting frame has a pivot mounted on one end thereof. A plurality of shells are respectively mounted on the supporting frames, each shell has a center hole defined therein. A plurality of blades are respectively disposed on the shells. Each blade has an assembling portion disposed thereon. Each assembling portion has a through hole defined therein. A plurality of coupling rods respectively positioned between every two adjacent shells. When the driving unit rotates, the shells synchronously rotate and driving the coupling rods to be moved for simultaneously driving the blades to retractably fold/unfold. | 11-17-2011 |
| 20120237339 | ADJUSTABLE RING - A charging device adjusting ring for a variable turbine and/or compressor geometry is disclosed. The charging device may include at least one inwardly directed recess for receiving at least one blade lever heads of a blade lever, wherein each recess comprises at least two lateral flanks. Additionally, at least one of the at least two flanks has a curved shape, and wherein the at least two flanks have a predefined deviation from a parallel arrangement. | 09-20-2012 |
| 20130156551 | INFORMATION PROCESSING APPARATUS AND IMAGE FORMING APPARATUS - An information processing apparatus includes a fan having an impeller. The fan further has a first side and a second side opposite to each other. The information processing apparatus further includes a frame to which the fan is mounted in a predetermined orientation so that the first side of the fan faces the frame. The frame has a ventilation opening facing the impeller. A resilient member is provided on the frame so as to face the fan. The fan has a supporting member on the first side and an opening on the second side. The supporting member faces the resilient member. | 06-20-2013 |

| 20100183430 | Turbine for driving a generator in a drill string - The invention is directed to a turbine with a housing mountable in a drill string and having an inlet opening and an outlet opening for a fluid conveyed through the drill string, and with an impeller arranged in the housing and adapted to be impinged upon by the fluid flowing into the housing, wherein the impeller is axially movably mounted and yieldably supported against the afflux direction in such a way that the supporting force of the yielding support increases as the axial movement of the impeller increases. To reduce the dependence of the turbine rotational frequency and turbine performance on the feed rate and to avoid overloading of the generator, the housing includes in the range of movement of the impeller a frontal first housing section of smaller inner diameter as seen in the afflux direction and a rear second housing section of larger inner diameter as seen in the afflux direction. | 07-22-2010 |
| 20110038713 | Dry running flexible impeller pump and method of manufacture - This invention relates to a Dry Running Flexible Impeller Pump and Method of Manufacture designed to provide a flexible impeller pump capable of being run dry for extended periods of time without damage. The pump's components are comprised of low friction materials limiting the heat of friction created by the impeller in use. The impeller is cast of pre-molding silicone substrate containing a quantity of mold release that will not prevent the deposition of a low friction compound coating on the surface of the impeller in a mold that is treated with a low friction industrial coating. Once the impeller is removed from the mold it is solvent cleaned, vacuum baked at a temperature high enough to drive off residual traces of mold release or compounds used to maintain the silicone substrate in suspension, and then coated with a polymer of Poly Para Xylylene by vacuum deposition. | 02-17-2011 |
| 20140308114 | DUST-PROOF FAN - An exemplary dust-proof fan includes a frame, a stator mounted in the frame and a rotor received in the frame. The rotor includes a bracket and multiple blades pivotably mounted to the bracket. The bracket includes an inner ring and an outer ring surrounding the inner ring. Each blade has an inner pole inserted into the inner ring and an outer pole inserted into the outer ring. The blades are spaced from each other to form multiple airflow passages therebetween when the dust-proof fan is in use. The blades are overlapped with each other to close the airflow passages when the dust-proof fan is not in use. | 10-16-2014 |
| 20160061183 | WATERMILL DEVICE AND METHOD OF GENERATING ELECTRICAL ENERGY BY MEANS OF SUCH A DEVICE - A watermill device for use in flowing water, including water-guiding means that define at least one substantially horizontal flow channel with a water supply range situated upstream during operation and a water discharge range situated downstream during operation, at least one blade wheel provided in the flow channel and having a rotation shaft that is oriented substantially perpendicularly to the direction of flow, at least three blades which are designed such that when moving with a motion component in the direction of flow they have a comparatively high coefficient of resistance to the water flowing through the at least one flow channel and when moving with a motion component against the direction of flow they have a comparatively low coefficient of resistance to the water flowing through the at least one flow channel, and transmission means for transmitting the rotary motion of the rotation shaft of the at least one blade wheel to a permanent-magnet generator. | 03-03-2016 |
