Abstract: Abstract Density Modulated Electron Beam Tube With Enhanced Gain An electron beam tube is described, having a flat cathode and a flat, close-spaced grid to density modulate the beam.  The beam passes through an apertured anode and then through a hollow drift tube which is the central conductor of a coaxial resonator.  A gap in the drift tube extracts wave energy from the density modulated beam.     The cathode-grid region is electrically isolated from the output resonator by the length of the drift tube which is cut off as a waveguide. The circuit is thus completely grounded-grid.  The input resonator, a coaxial line connected across the cathode-grid space, is loaded by the input conductance, so as to reduce the gain.  The invention increases the gain by introducing regeneration between the grid-anode space and the cathode-grid space.  This is done by a coupled coaxial resonator system.

Abstract: ABSTRACT A process for forming cloth-covered cushion articles. A mold is provided having the shape of the desired cushion article. In one form, a cloth covering is drawn into the mold. Foamable material is poured into the mold and cured to form the cushion article. The covered cured article is removed from the mold and heated to at least the heat-fixable fiber set temperature of the cloth, as the cured foam acts as a male mold to hold the cloth in contour during heat setting. In another form, the foam is poured directly into the mold and cured.          The cloth covering then is placed over the cured cushion and set.

Abstract: STRUCTURAL GRAPHICS REPRESENTATION            ABSTRACT     The product of this invention is visual  representation of  construction projects--such as bridges, buildings, dams, industrial plants, or means of transport--so as to emphasize project urgencies.   Novel depiction of structural features, both as scheduled and as constructed,  enables urgencies  of time, cost, etc., to be emphasized.   Gradations of emphasis are  expressed  independently of language,  by  boldness  of shading:  shown in monochrome as continuity and thickness of line; in polychrome, by brightness and hue of color, usually following the order of the spectrum.   During  construction, urgencies  associated with deviations from the  schedule--or variances  from  the budget--are emphasizable  by  depicting overdue (or overly costly) structural increments shaded more boldly than on-time (or within budget) structure This visual product results from a process or procedure involving identifying and sequentializing work activities of given durations into appropriate order to produce a schedule of  the work activities,  including start and finish  dates, together  with their respective resulting  structures.  This procedure also involves storing and retrieving the foregoing, and related data, such as quantities and costs of work crews or materials, and depiction data for the resulting structure. Although, in principle, accomplishable manually, in practice the  procedure preferably is machine-assisted,  such as by a digital computer programmed to carry out the desired steps.     Display of the visual product includes both  transient depiction, as on a video screen, and non-transient depiction via a plotter or printer.  Uses include not only instruction of  personnel  to improve actual on-the-job construction and cost  control but also compilation of a succession  of  such structural depictions,  so emphasized by line or color, into a permanent visual history of project urgencies.

Abstract: ABSTRACT    A signal processing scheme through which the receiver may, at any time, synchronize or resynchronize itself to the transmitted data signals that are received over a dynamic dispersive channel.  At the transmitter, bursts or sequences of known symbols are interleaved with unknown data.  At the receiver incoming frames of signals (containing interleaved bursts of known data and unknown data) are processed in a manner similar to the processing of spread spectrum encoded data.  A replica (or respective replicas) of the known signal burst(s) is (complex) correlated with the incoming signal to locate and lock onto a known (PN) reference symbol burst.          Once a known symbol block has been located, a symbol rate clock (bit sync) is adjusted to track out any offset in the timing used for sampling the received data.  This is followed by coarse and fine frequency offset adjustments to enable the local oscillator to lock onto the transmitted frequency.

Abstract: ABSTRACT OF THE DISCLOSURE      A navigation method for the navigation of a vehicle employing direction and longitudinal movement sensors.          Signals from the sensors are fed to a position computer which determines the vehicle position relative to a coor-dinate grid system.  When the vehicle reaches a position of known coordinates the position values which are determined from the sensor signals are corrected with reference to the known coordinates, and a Kalman filter is provided which effects an error estimate and subsequently a correction value determination from the error estimate which results in a significant increase in accuracy of the displayed navigation data.  The particular advantage of the method is the use of uncomplicated sensors which are able, in connec-tion with the Kalman filter, to obtain highly accurate vehicle position data.

Abstract: Abstract This invention relates to inks, and, more particularly inks that are useful for printing on low adhesion backsize coatings.         In many applications of pressure-sensitive adhesive webs, it is desirable to have a printed message or design on the adhesive-free side of the web. When some commonly available inks are used for such printing, a difficulty is encountered which arises from the tendency of the print to transfer to the adjacent adhesive-coated side when the web is unrolled, particularly if the printed web is retained in roll form for prolonged periods of time at elevated temperatures. When other commonly available inks are used, the adhesion of ink to the adhesive-coated side frequently is so strong that the web breaks when an attempt is made to unroll it. This is particularly the case when highly aggressive adhesives are used.         This invention involves an ink composition comprising a conventional flexographic ink stock, a wax, and a chlorinated polyolefin.  This ink composition can be used to print webs, e.g. tapes, bearing a low adhesion backsize on one major surface thereof and a pressure-sensitive adhesive on the other major surface thereof.
