    • A pressure relief system and a non-intrusive, low chatter pressure relief valve for use with such as system are disclosed. The pressure relief valve allows excess pressure in a pressurized fluid line to flow through a flow return line to a fluid reservoir when the fluid pressure exceeds the valve's pressure limit setting. The establishment of a uniform channel between the valve stem and the inner surface of a housing in which the valve stem is slidably located, as well as the use of a vent and sight tube to remove air from the top portion of the housing upon a spring being compressed during the opening of the valve, reduces the occurrence of pulsation and vibration when the valve is cycled between its open and closed positions. When the valve is in its closed position, the bottom end of the valve stem is in close proximity to the inner surface of the main fluid passageway in the pressurized fluid line, but does not intrusively interfere with the flow of fluid through the main fluid passageway.

    • This invention discloses an antenna element (12) or an array of antenna elements (52) for use in multifunctional systems which exhibits wide bandwidth, small size, polarization diversity and conformality. In one preferred embodiment, an array of circular conductive patches (56,58) are formed on a dielectric substrate (54) in which adjacent patches are formed on opposite sides of the substrate (54). Each of the opposite conducting patches (56,58) are configured to form a dual flared slotline such that an electric field created between the two conductive patches (56,58) will exhibit a wide range of impedance matching to free space. By exciting the conductive patches (56,58), radiating electromagnetic waves having a polarization with respect to the orientation of the slotlines is produced. By this, a single array of antenna elements (52) can be used in a multifunctional system.
    • 本发明公开了一种在多功能系统中使用的天线元件(12)或天线元件阵列(52),其具有宽带宽,小尺寸,极化分集和一致性。 在一个优选实施例中,圆形导电片(56,58)的阵列形成在电介质基片(54)上,相邻片形成在基底(54)的相对两侧。 每个相对的导电贴片(56,58)被配置为形成双喇叭形槽线,使得在两个导电贴片(56,58)之间产生的电场将表现出宽范围的阻抗匹配到自由空间。 通过激励导电块(56,58),产生相对于槽线的取向辐射具有极化的电磁波。 由此,可以在多功能系统中使用单个天线元件阵列(52)。
