  • Polyethylene films
    Patent number: 7101629
    Abstract: A film comprising a polyethylene composition, the polyethylene composition in one embodiment comprising a high molecular weight component having a weight average molecular weight of greater than 50,000 amu and a low molecular weight component having a weight average molecular weight of less than 50,000 amu; the polyethylene composition possessing a density of between 0.940 and 0.970 g/cm3, and an I21 value of less than 20 dg/min; characterized in that the polyethylene composition extrudes at an advantageously high specific throughput at an advantageously low melt temperature, and wherein the film has a gel count of less than 100.
    Type: Grant

  • Wide-band L-band corporate fed antenna for space based radars
    Patent number: 5227808
    Abstract: A large antenna array is constructed in sub-arrays which are supported in a stacked and folded (stowed) condition, and then deployed by first unfolding and then expanding the stack. The sub-arrays are compressed together to yield a very compact stowed configuration, due to the absence of a continuous ground planes. The compressed sub-arrays are contained within a foldable cage like frame.
