  • Patent number: 10535912
    Abstract: A power divider capable of implementation in a compact multilayer surface mount component to perform power division/combining with low insertion loss, wide bandwidth, design flexibility and high power handling capabilities. The power divider has a first pair of coupled transmission lines interconnecting the input to the outputs, a second pair of coupled transmission lines interconnecting the output ports to grounded isolation resistors, and a single transmission line interconnecting the second pair of coupled transmission lines. The surface mount implementation is by a first layer supporting the ports, a second layer providing edge coupled lines, a third layer having ground plane, a fourth layer and a fifth layer each supporting one of a pair of broadside coupled lines, a sixth layer with another ground plane, and a seventh layer including a single line interconnecting the broadside coupled lines.

  • Patent number: 7121419
    Abstract: The combination of a closure (110) and an in-bore fitment (201) is provided for a container. The closure (110) comprises a generally plain crown (120) with a tubular skirt (130) depending from its periphery. The tubular skirt (130) has a first weakened zone (140) defining a first tamperevident portion (150); the first weakened zone (140) is adapted to break on first opening of the container. The tubular skirt (150) has a second weakened zone (190) defining a second tamperevident portion (150). The second weakened zone (190) is protected from breakage on first opening of the container but is arranged to break if an attempt is made to remove the in-bore fitment (201) from the container.

  • Patent number: 6817479
    Abstract: A closure (2A) overlies a liner (6) which seals a container mount defined by a peripheral edge (12) of the container. The liner (6) includes a sealing flange (31) having an upstanding outermost terminal rim (40) of resilient material which is folded inwardly during closing movement of the closure shell (2A) toward the sealing flange (31) to form an unflattened fold constituting a biasing means for biasing the periphery of the sealing flange (31) against the peripheral edge (12) of the container mouth.
