    Abstract: A method and apparatus for obtaining seismic vibrator reflection data is disclosed with a significant signal to noise ratio. The earth is sinusoidally vibrated with source vibrations linearly varying over time. The amplitudes of the reflections from the subsurface strata interfaces are sensed and multiplied by the amplitude of the source vibrations, resulting in a first representation of the product as a function of time. A second representation of the product is calculated in association with negative values of time, such that phase consistency between the two representations is maintained. The two representations are then mathematically combined, with values of zero associated with all other values of time. The two representations are then linearly transformed into a function of frequency, and loaded into an array for computer operation. An inverse Fourier transform is the performed on the combined representations as a function of frequency, resulting in a timedomain representation of the combined representations indicating the delay times between the source vibrations and the sensed reflections. After various mathematical steps, the waveform is displayed in a form adapted to geophysical analysis.

    Abstract: A database publishing system uses a plurality of microprocessors for flowing manuscript material such as text and graphics into predefined entities making up the structure of a publication according to predetermined attributes associated with each entity, and for imaging manuscript material in a sequence of processing stages with each stage including a plurality of processing operations. In operation, the structure and appearance of a publication can be defined in advance before entering the manuscript material making up the publication. Furthermore, manuscript material making up a plurality of publications can be in process at the same time in various processing stages in order to image the publications in assembly line fashion.
