  • Fixed patch array scanning antenna
    Patent number: 6100846
    Abstract: An antenna, particularly adapted to produce a scanning beam usable for radar and communication applications, includes a frame. Attached to the frame is a reciprocating device that is operatively connected to a reflecting conductor. Spaced by a uniform gap from the conductor is an elongated dielectric waveguide carried on a conductive layer of a laminate supported by the frame on an input side of the antenna. The waveguide covers a set of spaced apart apertures in the laminate conductive layer. Joined to the laminate conductive layer on an opposite output side of the antenna is a dielectric layer. On an outer surface of the laminate dielectric layer is a set of spaced apart conductive patches that align with the laminate conductive layer apertures. During operation of the antennas an electromagnetic wave is transmitted through the waveguide to pass through the laminate apertures and energizes the patches.

  • Diisocyanate-modified polyesters as hot melt adhesives and coatings
    Patent number: 4166873
    Abstract: Diisocyanate-modified polyesters formed by heating 100 parts of a polyester with about 2 to 10 parts of a diisocyante to above about 260.degree. C. are useful as superior hot melt adhesives and as durable coatings.

  • Method of bonding utilizing a heat activated polyamide adhesive
    Patent number: 3939029
    Abstract: High strength structural metal-to-metal bonds can be achieved in 10 to 15 seconds by placing a resinous polyamide capable of imidizing between the metal surfaces to be bonded and heating the composite to a temperature sufficiently high (.gtoreq. 400.degree.F) to induce imidization.
