  • Patent number: 8053561
    Abstract: The invention is a proteinaceous construct comprising a Factor VIII molecule having at least a portion of the B domain intact, which is conjugated to a water-soluble polymer such as polyethylene glycol having a molecular weight of greater than 10,000 Daltons. The construct has a biological activity of at least 80% of the biological activity of native Factor VIII, and the in vivo half-life of the construct is increased by at least 1.5 fold as compared to the in vivo half-life of native factor FVIII.

  • Patent number: 4561076
    Abstract: A method and apparatus for underwater ranging with the aid of sonic pulses, by irradiating a given transmitting area with sonic energy pulses from a transmitter mounted in a marine vessel, receiving sonic energy echoes reflected from bodies in the transmitting area in a manner which is selective with respect to direction in a plurality of receiving sectors arranged in a fan shape, and associating the received echoes with respective reflection centers within the respective receiving sectors on the basis of associated sonic pulse travel times. Reception is carried out on a second marine vessel different from the vessel carrying the transmitter and which travels at a rearward offset position from the vessel carrying the transmitter at such a distance therefrom that the receiving sectors cover at least part of the given transmitting area, and the azimuthal width of the transmitting area is made very small.
