| 20090260792 | TUBE WITH FINS HAVING WINGS - Fins are formed monolithically from the material of a tube body. The fins extend from the tube body outer surface, and include a fin base and a fin top. Wings extending from a fin side surface between the fin base and fin top can produce upper and lower channels between adjacent fins. Depressions can be formed in the fin top with platforms below the depressions. The tube can also include helical ridges on an inner surface of the tube. The tubes are used for heat transfer, and can be included in shell and tube heat exchangers. | 10-22-2009 |

| 20100303126 | Signal Modulation Method - The present invention provides a signal modulation method which includes the following steps: a input signal is channel encoded, and the channel encoded signal is processed by the following one or several ways: channel scrambling, interleaving, duplicating and puncturing; the signal being processed is divided into two components I and Q, wherein the two components I and Q compose a signal pair; the signal pair is divided into more than one path, and respective path of signal is quadrature phase shift keying spectrum spreading modulated using different spectrum spreading sequence and is orthogonally modulated in order that the peak-to-average power ratio of the respective paths of signal being orthogonally modulated are obtained; and a path of signal having the smallest peak-to-average power ratio is selected to be outputted as an output signal. The signal modulation method can reduce the signal PAPR significantly, not only is propitious to the design of the power amplifier, but also reduces the cost of the power amplifier. | 12-02-2010 |

| 20110293811 | PARTICULATE FAT-CONTAINING POWDER, ITS PREPARATION AND ITS USE - The invention pertains to a foamer, creamer, topping base or whitening powder (or whitener), containing 0.05-5 wt % of one or more phosphopeptide(s), based on the total dry weight of the powder. The powder may be characterized in that, upon addition of a liquid, it provides said liquid with a creamy, foamy and/or whitened appearance; it contains conventional amounts of fat, protein and carbohydrate. The phosphopeptides preferably comprise casein phosphopeptides (CPP). | 12-01-2011 |
