Abstract: PROCESS FOR PREPARING AQUEOUS COATINGS COMPRISING DISPERSIBLE EPOXY RESIN-ACID POLYMER ESTER          ABSTRACT          In a method for preparing a coating composition, an ionic polymer component containing sufficient carboxyl groups to render itself dispersible in water in neutralized form is prepared by reacting an epoxy resin containing 1,2-epoxy groups and an addition polymer containing carboxyl groups such that the resultant ionic polymer contains hydroxy ester groups from the reaction of 1,2-epoxy groups on said epoxy resin with carboxyl groups on the preformed addition polymer, and is substantially free of unreacted 1,2-epoxy groups.  The ionic polymer component is then dispersed in water with the addition of ammonia or an organic amine neutralizing agent in an amount sufficient to render the composition stably dispersible in water; and an addition polymer different from the addition polymer containing carboxyl groups is incorporated into the aqueous dispersion of said ionic polymer component.

Abstract: ABSTRACT          Velocity Tapering of Comb-Quad Traveling-Wave Tubes The "comb-quad" slow-wave interaction circuit for a traveling-wave tube consists of a pair of metallic ladders whose rungs cross, the rungs of one ladder passing through the spaces between the rungs of the other ladder.  The phase velocity of the circuit wave is tapered to a lower value at the output end by gradually enlarging the axial open spaces between the longitudinal bases of the ladders and the sur-rounding envelope.  The periodic elements of the ladders are all exactly alike, simplifying the con-struction.     The slowing of the wave velocity is greater at the lower-frequency end of the passband, providing improved efficiency over the operating band.

Abstract: ABSTRACT OF THE DISCLOSURE    To reduce space requirements,  vibrations and cer-tain stresses in an engine,  a different one of two pistons is mounted on each end of a single piston rod to which the crankshaft is attached by a cylindrical shaped connector that orbits around the crankpin while rotating inside the piston rod.  The crank interfaces directly with the piston rod through gear portions or a cam-cam follower through the center of each stroke.  To reduce vibrations and certain stresses in an engine, a dif-ferent one of two pistons is mounted on each end of a single piston rod to which the crankshaft is attached by two arms extending orthogonally from its central por-tion, each arm being mounted to a different one of two different connecting rods.   To balance inertia forces, two oppositely rotating crankshafts are counter-weighted to balance the inertia forces of the assembly in its axis of oscillation and to balance each other outside that axis of motion, or two piston assemblies oscillate opposingly in the same axis eliminating the need for the crankshafts to balance their inertia forces.

Abstract: ABSTRACT OF THE DISCLOSURE           A new and useful fluorescent chromophore has been isolated and identified which has been observed in proteins exposed to glucose over time, and whose fluorescent properties closely resemble those of the polypeptide after it undergoes advanced glycosylation.  The chromophore is structurally identified by the formula:                     is named 2(2-furoyl)-4(5)-(2-furanyl)-1H-imidazole, and is believed to be one of the end products of extended non-enzymatic polypeptide glycosylation, which results in the state known as non-enzymatic browning (NEB); the measurement of this chromophore makes possible both qualitative and quantitative assessment of the degree of aging; diagnostic and test kits are also disclosed.

Abstract: OPTICAL WAVEGUIDE MANUFACTURE          Abstract of the Disclosure Optical waveguide having a fused silica core and a fluorine doped silica cladding is made by heating a cylinder of silica in -fluorine, the cylinder initially having an outer annular particulate or porous region which is dried by the fluorine and into which fluorine diffuses to lower the refractive index of the silica when fused.  The cylinder is made by depositing particulate silica onto a mandrel, drying the silica in chlorine, and heating the silica to densify it.  Further particulate silica is deposited and is then heated in a fluorine-containing gas to dry, fluorine diffuse, and sinter the porous outer part of the silica.  The resulting tubular silica preform is heated to cause fusion of the porous silica and to collapse the tubular preform into a rod From which optical waveguide is drawn, the waveguide having a fluorine doped silica cladding.  The fluorine drying and diffusion steps produce HF which is extremely corrosive.  To avoid escape of HF, the fluorine drying, diffusion and consolidation steps are all performed within a single protective fused silica tube.  After termination of the drying, diffusion and consolidation steps, the protective silica tube is collapsed so as to become an outer layer of the preform and is incorporated within fiber drawn From the preform.                             - i -
