Abstract: An apparatus comprising: a first waveguide port configured to support first signals having a first polarisation state; a second waveguide port configured to support second signals having a second polarisation state orthogonal to the first polarisation state; a third waveguide port configured to support combined signals comprising a first signal component having the first polarisation state and a second signal component having the second polarisation state; a waveguide structure, disposed between the first waveguide port, the second waveguide port and the third waveguide port, configured to: split a combined signal received via the third waveguide port into first and second signal components and to provide the first signal component to the first waveguide port and the second signal component to the second waveguide port, and/or combine a first signal received via the first waveguide port and a second signal received via the second waveguide port into a combined signal and to provide the combined signal to t

Abstract: In one embodiment, a waveguide structure, disposed between a first waveguide port and second and third waveguide ports, is configured to split, in the frequency domain, the first signal into the second and third signals, and/or combine, in the frequency domain, the second and third signals into the first signal. The waveguide structure includes an asymmetric cross-sectional shape defining first and second aperture regions having respective first and second extents, wherein the second extent is less than the first extent. The waveguide structure is arranged relative to the second and third waveguide ports such that the third waveguide port is predominantly adjacent the first aperture region, and the second waveguide port is predominantly adjacent the second aperture region.

Abstract: A container assembly including a first and second component. The first component includes a first base, a first plurality of side walls extending upwardly from the first base, and a first lip extending outwardly around a perimeter of the first plurality side walls. The second component includes a second base, a second plurality of side walls extending upwardly from the second base, and a second lip extending outwardly around a perimeter of the second plurality of side walls. The first and second components are convertible between at least a spaced configuration, a first locked configuration, and a second locked configuration. The first and second components are completely separate from one another in the spaced configuration and define an interior in the first and second locked configurations. An orientation of at least one the first and second components is different in the first and second locked configurations.

Abstract: A container clearly indicates that it has been opened after a store clerk loads food into the base of the container and closes a covering of the container onto the base. The covering (16) includes a peripheral cover portion (22) that becomes fixed to a peripheral base portion (32) when the clerk initially closes the container. To thereafter open the container, a person forcefully lifts a tab (30) on the covering to tear the covering along a long tear line (26) that separates the peripheral cover portion (22) from a lid (24) formed by a radially inner covering portion. The base (12) is fixed to the peripheral covering portion (22), and together they form a base device (40). After the lid has been torn free of the peripheral covering portion, the lid can be closed and latched to the base device and then can be easily opened again.

Abstract: A food container system can include a tray with a bottom and a side wall, which together define a recess. The tray can have an array of ribs on the bottom panel that can extend to the side wall. The side wall can have female ribs that extend from the bottom panel to the top edge of the side wall. An inverted corner creating a concave shape on the exterior edge of the tray can be disposed at the intersection of the bottom wall and the side wall. The tray can include a rim that extends around the perimeter of the tray, which can accept a complimentary surface of a lid.

Abstract: This invention relates to a process for the manufacture a coated bumper, which steps are practical and simple, but at the same time, highly efficient for manufacturing coated bumpers, that permits the use of same equipment as those used to manufacture conventional fences. Likewise, this invention relates to a bumper highly efficient for use in any type of vehicle, since it has and exceeds all the aesthetical and mechanical and corrosion resistance characteristics of bumpers found in the state of the art.
