International Classification:

G01D 1510

US Classification:

346157

Abstract:

A multicolor electrostatic plotter is disclosed and includes an image head for imparting a charge pattern to a web medium to be imprinted and a plurality of toner means associated with different colors in which different colors are successively applied to portions of the medium by repeatedly driving and rewinding a portion of the medium past the image head and the plurality of toner means for charge and toner application to imprint multiple color rasterized images on the medium by the use of electronic circuitry which imprints a reference track on the medium during the first color pass and then optoelectronically detects deviations, generally perpendicular to the directional movement of the medium, of the medium during successive color passes substantially instantaneously with the deviations and which electronically adjusts the input data from a remote rasterizer by an amount equal to the substantially instantaneous offset so that lines of raster data are shifted by an amount substantially equal to the instantaneous displacement of the medium prior to charging the particular electrodes on the image head corresponding to the charge patterns for the next successive particular lines of raster information which are to be imprinted for the particular color image.

Abstract:

A portable and collapsible dolly and track system is movably supporting a tripod which retains a camera or the like thereon. Once the dolly and the track have been assembled, the dolly is positioned on top of the track. A tripod is positioned on the dolly, and thereby the dolly with the tripod will roll along the track in a horizontal plane with the camera thereon for filming a scene or taking photographs. The track comprises a pair of opposite longitudinal parallel rails arranged in a space apart relationship by three pivotable transverse bars. The pair of rails are comprised of a plurality of cylindrical tubes. The plurality of cylindrical tubes are held together with a unique BUNGEE cord type joining member in order to enable them to be very quickly and efficiently assembled and set into place and then disassembled for storage. The track can be folded for storage by withdrawing the ends of the plurality of cylindrical tubes from each other.
