  • Patent number: 4214269
    Abstract: A digital scan converter is disclosed for processing the sequence of analog signals supplied by a sector scanning surveillance system to form a signal compatible with television type display devices. The signals supplied by the surveillance system are digitized by an analog-to-digital converter at a rate proportional to the cosine of the azimuthal scan angle that is associated with each analog signal to thereby effect a first portion of the required conversion from the polar coordinate format of the surveillance system to the Cartesian coordinate format of the television display. The digitized signals are stored in a memory so as to permit addressing of a set of stored data that corresponds to one horizontal trace of the television display.

  • Patent number: 3973926
    Abstract: A method by which particle separation is accomplished by taking advantage of the large difference in the diffusion rates between the ionized and neutral components of a gaseous mixture, in the presence of a magnetic field. Means for separating isotopes in a continuous and commercially successful manner. Apparatus in which the desired component is selectively ionized, accelerated and guided by a magnetic field along a predetermined axis, while the neutral particles are transversely removed by means of vacuum or cryogenic pumps.
