  • Multiple depth water sampling system
    Patent number: 4462265
    Abstract: A towed system for collecting water samples from a plurality of individual depths for serial presentation to analyzing instruments utilizes a plurality of pressure actuated collection devices separated by vertical hose segments through which water is pumped from a depressor. The flow is modulated to actuate collection device valves so as to introduce the samples in stacked relation.

    Inventor: Charles R. Rein
  • Electronic card mount and heat transfer assembly for underwater vehicles
    Patent number: 4184539
    Abstract: A plurality of electronic circuit cards are edge mounted in heat transfer lation to a pair of spaced parallel card mounting plates extending from a bulkhead of an underwater instrumentation vehicle hull having a tubular cover section adapted to be moved into and out of covering relation to the cards and mounting plates. Spring biased slip plates provide heat transfer paths from the mounting plates to the cover section for dissipation to ambient water.

  • Adjustable magnetic gradiometer
    Patent number: 3962628
    Abstract: A cryogenic magnetic field gradiometer is described wherein adjustments of areas presented by a superconducting wire loop, that is confined in a support structure within a cryogenic environment, are adjusted mechanically through wire positioning elements operated by a plurality of parallel shafts extending to the exterior of the environment. In one embodiment the positioning elements are cams that cooperate to position portions of a wire loop, while in another form bell crank levers are used.
