    摘要: The instant device is a forming board position control system. A forming board fitted with the instant invention is positioned at various distances from and with virtually perfect constant parallelarity to the lie of the frontal plane of a headbox in apposition to the forming board. A computer controlled motor causes a parallelwise positioned pair of worm gear jacks mounted to the board, to move the board longitudinally to and fro through a distance from the frontal plane of the headbox as is determined with reference to manually manipulated computerized settings until the system stops perforce of a signal to such effect received by a controller computer as the result of interaction as between a magnet affixed to the base of one of two mounting plates to which the board is also mounted and a transducer closely positioned thereto and connected directly to the computer.

    摘要: A thermal ice penetration method and apparatus for melting a hole through ice preferably utilizing thermochemical heating by exothermal reaction between water supplied at least in part by the melting ice and a thermochemical reactant, preferably lithium and/or other alkali metal or alkali metal alloy. A number of ice penetration systems and devices are disclosed which utilize the thermal ice penetration to deploy payloads, such as sensors, transducers, antennas, instruments, weapons, or the like, through polar ice either downwardly from the ice surface into the water below the ice or upwardly from the underside of the ice through the ice surface.
