  • Underwater towing of marine vessels
    Patent number: 6416369
    Abstract: A marine vessel is propelled under maneuvering control in a selected direction and travel speed through a body of seawater, by propulsion exclusively provided for by one or more submerged towing module pods attached to the underside of the vessel hull at locations between its bow and stern. Each of such towing pods may be attached to the vessel and spaced therebelow by an elongated cable so constructed for enclosure within a drag reducing fairing. Each of such cables has internal portions thereof arranged to electrically conduct current between the marine vessel and the towing pod for controllable operation of its propulsive equipment, while transferring the mechanical towing force so produced to the vessel.

  • Radar tank level indicating system for measurement of water content in shipboard tank involving identification of fuel-water interface
    Patent number: 6353407
    Abstract: A microwave radar signal system generates separate level indicating signals for transmittal through a sounding tube into a contamination tank having a mixture of fuel and gross free water collected therein. The separate level indicating signals are thereby respectively reflected from the level of a top surface of the collected liquid mixture and a lower level of an interface between the fuel and the gross free water portions of the mixture to respectively provide data for determination of total liquid volume collected and the volumetric content of the fuel therein. The interface level location is established by means of a floatation ball disposed within the sounding tube, from which level indicating signals are reflected.
