20090015175 | Brightness control system for LED lighting devices - The present invention provides a brightness remote control system for LED lighting device. There are two control modes, namely automatic mode and manual mode. At automatic mode, the brightness of the LED lighting device changes as the brightness of the environment changes to maintain preset constant brightness. At manual mode, the brightness of the LED lighting device can be changed instantaneously or at preset time or times. | 01-15-2009 |

20120292011 | CRUDE OIL PRODUCTION EQUIPMENT - A crude oil production equipment includes a submersible pump coupled with a driving shaft, a linear motor, an oil pipe, a well casing, a filter pipe, an outer passage, an inner tube, an upper valve ball, a piston and a lower valve ball. During down stroke of the driving shaft, a suction force is produced to suck crude oil from the well casing into the upper chamber of the inner and the piston forces crude oil out of the lower chamber of the inner tube into the inner passage and then the outlet of the oil pipe. During up stroke of the driving shaft, the piston forces crude oil out of the upper chamber into the lower chamber, and the driving shaft enters the upper chamber and the lower chamber to force crude oil out of the lower chamber out of the oil outlet of the oil pipe. | 11-22-2012 |
