Abstract: Fabricated articles are disclosed which comprise a polypropylene impact copolymer. The propylene impact copolymer composition comprises from 60 to 90 percent by weight of the impact copolymer composition of a matrix phase, which can be a homopolymer polypropylene or random polypropylene copolymer having from 0.1 to 7 mol percent of units derived from ethylene or C4-C10 alpha olefins. The propylene impact copolymer composition also comprises from 10 to 40 percent by weight of the impact copolymer composition of a dispersed phase, which comprises a propylene/alpha-olefin copolymer having from 6 to 40 mol percent of units derived from ethylene or C4-C10 alpha olefins, wherein the dispersed phase has a comonomer content which is greater than the comonomer content in the matrix phase. The propylene impact copolymer composition is further characterized by having the ratio of the matrix MFR to the dispersed phase MFR being 1.2 or less.

Abstract: The present invention provides bicomponent fibers, a method of producing bicomponent fibers, nonwoven materials comprising one or more such bicomponent fibers, and a method for making such nonwoven materials. The bicomponent fibers according to the present invention comprise (a) a first component comprising a polymeric material selected from the group consisting of polypropylene, polyester, and polyamide; and (b) a second component comprising a polyethylene composition comprising less than or equal to 100 percent by weight of the units derived from ethylene; and less than 20 percent by weight of units derived from one or more ?-olefin comonomers; wherein the polyethylene composition has a density in the range of from 0.945 to 0. 965 g/cm3, a molecular weight distribution (Mw/Mn) in the range of from 1.70 to 3.5, a melt index (I2) in the range of from 0.2 to 150 g/10 minutes, a molecular weight distribution (Mz/Mw) in the range of from less than 2.5, vinyl unsaturation in the range of from less than 0.

Abstract: A method and apparatus is disclosed for processing two or more signals received over a multichannel communication system to cancel or mitigate coupling and the effect of the channel on the two or more signals. In one embodiment a multichannel communication system utilizes DMT processing to transmit two or more signals over two or more channels. To recover the transmitted signal, processing in the receiver may comprise submitting the two or more signals to a matrix filter configured to cancel the effects of the channel, such as phase and magnitude distortion, and account for self FEXT. In addition, decision directed processing may occur, generating one or more cancellation signals based on the noise on the output of the matrix filter. By filtering the noise terms and generating a crosstalk compensation signal, the transmitted signal is recovered more faithfully and the performance of the communication system is improved.

Abstract: The present invention provides an automatic method and apparatus for weighing into portions. Feeding of single units is performed by separating the feeding channels for rough feeding and fine feeding so that the feeding up to the weighing station is separated. When weighed portions are too large compared to a predetermined value, the apparatus rejects the portions and returns them back to the feeding stream. By separating the stream of units into fine weighing and rough weighing, with a rejection of unsatisfied portions, the portions can accurately be weighed with high performance with apparatus that is both inexpensive and space saving.
