  • Publication number: 20080000207
    Abstract: A crop-processing device with a picking-up and cutting device for picking up and cutting an agricultural product. The crop-processing device furthermore has a discharge duct for discharging cut agricultural product from the crop-processing device, in which discharge duct first and second rotating accelerating elements are arranged for conveying the cut agricultural product through the discharge duct by contact with the cut agricultural product. The peripheral speed of the second accelerating element is greater than the peripheral speed of the first accelerating element. As a result, the acceleration up to the desired discharge speed, and thus the discharge of the product, is more uniform. Furthermore, the device requires less power than known crop-processing devices.

  • Patent number: 5795941

The crosslinkable polyolefin compositions are bidisperse blends of ethylene polymers of the same polymer family having differing number average molecular weights as obtained by deconvolution in which M.sub.n1 /M.sub.n2 >7, M.sub.n2 >3000 and 0.7.gtoreq.(A.sub.1 /(A.sub.1 +A.sub.2)).gtoreq.0.15 wherein M.sub.n1 represents the number average molecular weight of the first deconvoluted component, M.sub.n2 represents the number average molecular weight of the second deconvoluted component, and A.sub.1 and A.sub.2 are the relative proportions of the first and second components.
