| 20080199673 | Propylene Based Meltblown Nonwoven Layers and Composite Structures - The present invention relates to propylene-based nonwoven layers made by the meltblown process, and laminates incorporating such layers. The meltblown layers of the present invention comprise propylene copolymers characterized by having less than 50 percent crystallinity. The meltblown layers of the present invention show an improved combination of extensibility and tensile strength. The laminate structures of the present invention are characterized by a combination of low bending modulus with high peel strength. | 08-21-2008 |
| 20110092937 | POLYETHYLENE COMPOSITIONS, METHOD OF PRODUCING THE SAME, FIBERS MADE THEREFROM, AND METHOD OF MAKING THE SAME - The instant invention is a polyethylene composition, method of producing the same, fibers made therefrom, and method of making the same. The polyethylene composition according to instant invention comprises: (a) less than or equal to 100 percent by weight of the units derived from ethylene; and (b) less than 20 percent by weight of units derived from one or more α-olefin comonomers. The polyethylene composition according to instant invention has a density in the range of 0.920 to 0.970 g/cm | 04-21-2011 |

| 20080204134 | Power combiner - An embodiment of four-way binary power combiner consists of a first 1:1 transformer that combines a 50 ohm output impedance received from an output of a first power amplifier and a 50 ohm output impedance received from an output of second power amplifier to provide a 25 ohm first transformer output impedance at a first transformer output. A first 100 ohm difference resistor is connected between the first power amplifier output and the second amplifier output. The second 1:1 transformer combines a 50 ohm output impedance received from an output of a third power amplifier and a 50 ohm output impedance received from an output of a fourth power amplifier to provide a 25 ohm second transformer output impedance at a second transformer output. A second 100 ohm difference resistor is connected between the third power amplifier output and the fourth power amplifier output. A 50 ohm difference resistor is connected between the first transformer output and the second transformer output. A third transformer combines the 25 ohm first transformer output impedance and the 25 ohm second transformer output impedance to provide a 12.5 ohm output impedance at a third transformer output that is adapted for direct connection to a load. | 08-28-2008 |
