Abstract: Gaskets comprising either at least one homogeneously branched ethylene polymer or at least one elastic substantially linear ethylene polymer, at least one ethylene/carboxylic acid interpolymer; and at least one slip agent are disclosed. These gaskets may also contain enhanced polyethylenes produced by the direct polymerization of various combinations of novel elastic substantially linear olefin polymers in multiple reactors using either single or multiple catalysts. These gaskets may also be comprised of at least one ethylene polymer and at least one ionomer. The above mentioned gaskets may also contain slip agents and/or foaming agents. The gaskets are particularly useful for sealing food and liquid containers and do not contribute to taste and/or odor of the packaged product, which is especially useful in food-stuff applications.

Abstract: A multi-element, H plane, phase, dipole array antenna has a high gain over a wide angle in azimuth and over a controlled sector in elevation. Two printed wiring boards feed and physically support the dipole antenna elements. The phase and spacing of the dipole elements establish the radiation elevation angle, and a planar metallic reflector, spaced on the order of a half wavelength of the RF signal from the dipole array, interacts with the dipole-element pattern, to provide the wide angle azimuth gain.

Abstract: An improved rain resistance radome C-sandwich wall is constructed of thermoplastic polycarbonate material. The cores are either posts or tubes and are bonded to the skins with polyurethane. The percentage of core material to air is adjusted by electrical tuning to make the optimum dielectric value for use in the gigahertz radar frequency range.
