Abstract: APPLICATION OF:    NORWOOD K. TALBERT FOR:    PROCESS OF DEWATERING SEWAGE SLUDGE     ABSTRACT OF THE DISCLOSURE           A process for dewatering sewage sludge having a water content on the order of 75% to 95% and previously untreated for the release of such water.  The sludge is mixed with a chemical selected from the group consisting of urea and the common ammonium and potassium salts in relative quantities which produce a desired degree of phase separation.  The hygroscopic qualities of the chemical operate to remove water from the sludge to form a separate liquid phase of the chemical dissolved in water removed from the sludge, and a solid or semi-solid phase of the sludge solids with any remaining water.  The phases may then easily be separated with great simplification of subsequent handling, disposal or further processing of each.

Abstract: ABSTRACT             Underwater fish grading may be done in a fish pen de-fined by a rectangular floating walkway.  A flexible net in the pen is supported at its perimeter by the walkway or by support members thereon, and a pair of spaced-apart rigid members bridge the pen, each end resting on suitable support means.  Below that, a belly rope is passed below the net. A grading barrier, suspended from the rigid members, has a horizontal cross-member held well above water level.  An arcuate rim secured to both ends of the cross-member extends down in a vertical plane, and a series of vertical rods extend between and are secured to both the rim and the cross-member, the rods being evenly spaced apart to define grading passages between successive rods.  In cross section, the rim defines an exterior channel, and the flexible net is brought into snug contact with the exterior channel by means of the belly rope and is then anchored near the ends of the rim. Fish can swim from one portion of the pen to the other only if they can swim through the grading passages.

Abstract: VEHICLE GUIDANCE SYSTEM            Abstract of the Disclosure Terminal guidance of vehicles is accomplished by accurately determining true position and speed of the vehicle from terrain contour measurements and updating a dead reckon-ing navigation system with precision to permit navigation by following a programmed flight path.  A narrow beam radar altitude sensor measures vehicle clearance altitudes and a reference altitude sensor measures the vehicle clearance above a reference level.  These measurements are input to a digital processor for comparison to stored digital terrain contour reference data.  Recursive data matching is performed in the digital processor by a nonlinear Kalman filtering technique to provide vehicle position and vehicle velocity correction signals to a navigation controller that generates steering commands to the vehicle control system.  Three vehicle position and three vehicle velocity signals are generated and updated in the nonlinear Kalman filtering technique to give near real-time three dimensional position and velocity information.

The converter is a phos-phor or scintillator material which is modified to block ambient light,  The intensifier includes fiber optics input and output face plates with a photocathode-microchannel plate amplifier-phosphor combination,  Incoming radiation is conver-ted to visible light by the converter which is piped into the intensifier by the input fiber optics face plate.  The photo-cathode converts the visible light to electrons which are am-plified by a microchannel plate amplifier.  The electrons are converted back to light by a phosphor layer and piped out for viewing by the output fiber optics face plate.  The converter-intensifier combination may be further combined with it's own radiation source or used with an independent source.

The thermally crystallizable glass composition is produced by a process involving the steps of providing a quan-tity of uncrystallized chips of crystallizable glass having a thickness of about 20-25 mils, and a quantity of essentially fully crystallized glass having a particle size ranging between about -20 and +80 U.S. Series Sieve screen size; reducing the particle size of the uncrystallized glass and fully crystallized to a particle size range wherein essentially all of the uncrystallized glass and fully crystallized glass particles are less than 100 U.S.        Series Sieve screen size and wherein between about 65-78 percent by weight of the uncrystallized glass and fully crystallized glass particles are less than 325 U.S. Series Sieve screen size; blending the fully crystallized glass particles together with the uncrystal-lized glass particles in a ratio of between about 100-225 parts by weight of crystallized glass particles to one million parts by weight of uncrystallized glass particles to produce a uniform "master blend" of finely comminuted, crystallized and uncrystal-lized glass particles.
