    • The Locator Beacon (LB) is an 18 inch diameter hemispherical unit designed to be air dropped via parachute from a search aircraft near an aircraft crash site. The LB is self uprighting when it lands on the ground and its antenna is always oriented for maximum efficiency. When activated, the LB sends out a radio frequency signal on 121.6 Mhz and 243.2 Mhz, this signal can be tracked by aircraft or by ground parties equipped with directional locating equipment. The LB also contains a strobe light beacon to aid in visual acquisition of the unit. The LB remains in the active (broadcast) mode for approximately 20 minutes before resetting itself to the listening mode. External VHF activation of the LB repeats the LB broadcast and strobe light cycle for another 20 minutes.
    • 定位器信标(LB)是一个18英寸直径的半球形单元,旨在通过降落伞从飞机坠毁现场附近的搜索飞机上空降落。 当它落在地面上时,LB是自立式的,并且其天线总是朝向最大的效率。 当激活时,LB发出121.6 Mhz和243.2 Mhz的射频信号,该信号可以由飞机或配备方向定位设备的地面方跟踪。 LB还包含一个闪光灯信标,以帮助该单元的视觉采集。 在将自身重置为聆听模式之前,LB保持在主动(广播)模式约20分钟。 LB的外部VHF激活重复LB广播和频闪光循环另外20分钟。

    • A hydrophobic filler material for alkaline paper is disclosed. The filler material comprises finely divided particles of an inorganic material, a majority of particles having a surface all of which is substantially modified with a water soluble C.sub.12 -C.sub.22 fatty acid salt and a metal ion in an amount at least effective to complex all of the fatty acid salt present. An alkaline paper is disclosed. The alkaline paper comprises a hydrophobic filler material comprising finely divided inorganic material, a majority of particles having substantially all of their surface being modified with a water soluble C.sub.12 -C.sub.22 fatty acid salt. A method for improving sizing of alkaline paper is disclosed, comprising preparing a filler material and adding the same to cellulose fiber. The filler material is prepared by selecting finely divided particles of an inorganic material and substantially modifying all of the surface of a majority of the particles with a C.sub.12 -C.sub.22 fatty acid salt, forming a hydrophobic coating thereon.
