    摘要： 1. In a homing torpedo, in combination: means for providing a target searchhase of torpedo operation wherein said torpedo is controlled to change depth between predetermined search floor and search ceiling depths and simultaneously controlled to circle in azimuth, whereby to execute helical search action; means for switching, in response to target acquisition at any time during a search phase of torpedo operation, to a target pursuit phase of torpedo operation; and means for switching, in the event of and in response to target loss continuing for a predetermined period in a target pursuit phase, to a modified search phase of torpedo operation wherein said torpedo is initially controlled to execute circle search action while maintaining depth position at substantially that at which target loss occurred, for a predetermined period accommodating at least a complete azimuth circling turn, then controlled to revert to helical search action.

    摘要： 2. In an echo-ranging torpedo wherein spurious and true-target echo signalsay be received in the listening periods between repetitive search-pulse transmission instants, in combination: a receiver operative to convert received echo signals to steering command signals having characteristics corresponding to echo-source direction, said receiver including a target-recognition circuit and a gating relay which operates, with inherent delay, in response to recognition of each true-target echo signal; a steering control circuit, including steering relay and switch means, adapted to place said steering relay and switch means in a condition corresponding to echo-source direction as derived by said steering control circuit, when operative, from said steering command signals; means applying said steering command signals to said steering control circuit; means controlled by operation of said gating relay, in response to each reception and recognition of a true-target echo signal, to render said steering control circuit operative to respond to steering command signals stemming from subsequent echo signals during a predetermined interval, of the order of a few listening periods, following each said reception and recognition of a true-target echo signal, and steering apparatus responsive, when rendered effective, to said steering relay and switch means condition; said gating relay, when operated, controlling said steering apparatus to render it effective to respond to said steering relay and switch means condition.

    摘要： A temperature sensor arrangement which utilizes high Q temperature sensitive resonators coupled to an acoustic waveguide. Several resonators, each resonant at a different frequency, are positioned at various locations in a system to be monitored and an acoustic signal is sent down the waveguide. Reflected acoustic energy is examined for the presence of the various resonant frequencies. Since the resonant frequency of each resonator is temperature sensitive, the detected signals provide an indication of temperature at the respective various locations.
