Abstract: A method to produce thin films suitable for fabricating ferroelectric thin films. The method provides for selection of the predetermined amounts of lead, lanthanum, zirconium, and titanium precursors which are soluble in different solvents. Dissolving predetermined amounts of the precursors in their respective solvents in proportions such that hydrolyze reaction rate for each metal precursor will be approximately equal. The precursors and solvents are mixed, and water is added to begin a hydrolysis reaction. After the hydrolysis the solution is heated to drive off the excess water and solvent to promote the formation of a sol-gel. The sol-gel is then applied to a thin substrate and sintered to produce the ferroelectric film.

Abstract: A programmable interconnection circuit includes first and second ferroelectric capacitors which differentially store the programming state of the circuit. A principal application of the circuit is in the programming of cells within a gate array integrated circuit. The programmable circuit is non-volatile due to the storage of polarization state within the ferroelectric capacitors. Differential voltage states are applied to programming nodes which set the state of a cross-coupled amplifier that, in turn, drives p-channel and n-channel transistors which are connected between first and second nodes of the integrated circuit. A drive line signal applied to terminals of the ferroelectric capacitors goes between high and low voltage states to set differential polarization states into the capacitors.

Abstract: A method for removing sprinkler pipe from a field in which the sprinkler pipe is disposed in rows in the field with the sprinkler pipe in each row being formed as a sprinkler line by serially connected lengths of pipe. The method comprises grasping one end of the sprinkler line and pulling it from the field without entering the field along a line generally coaxial with the sprinkler line for a distance at least equal to the length of a section of sprinkler pipe. A length of sprinkler pipe is then disconnected from the line, and the next sprinkler pipe is grasped and the sprinkler line is pulled at least one additional pipe length without entering the field. That next length of sprinkler pipe is thereafter disconnected from the sprinkler line, and the procedure is repeated until the entire sprinkler pipeline has been removed from the field.

Abstract: A vehicle body sunroof assembly (30) for a roof opening (56) includes a sunroof (64) having a plurality of panels (66) that extend between upper edges of vehicle side doors (24) with a door-to-door construction. The sunfoor (64) also includes a flexible sheet-like cover (70) having connection (72) to the sunroof panels (66). The cover connections (72) to the panels (66) are spaced such that the cover is movable between a closed position where the panels are spaced from each other and an open position where the panels are positioned adjacent the rear edge of the roof opening in a partially overlapping relationship with the cover (70) stored therebetween in a folded condition.

Abstract: The compound (S)(+)-4,4'-(1-methyl-1,2-ethanediyl)-bis(2,6-piperazinedione) is prepared by treating propylenediamine tetraacetic tetraamide in a dipolar aprotic solvent with an alkali metal derivative of dimethyl sulfoxide to form a dialkali metal salt of (S)(+)-4,4'-(1-methyl-1,2-ethanediyl)-bis(2,6-piperazinedione); and neutralizing the dialkali metal salt.

Abstract: An apparatus for removing sprinkler pipe from a field in which the sprinkler pipe is disposed in rows in the field with the sprinkler pipe in each row being formed of serially connected lengths of sprinkler pipe having an elongate framework. Ground engaging means is carried by the framework. First and second sprockets are rotatably mounted on the framework in positions spaced apart longitudinally of the framework. An endless chain is mounted on the sprockets. A drive motor is provided. Control means for connecting and disconnecting the drive motor is provided to one of said sprockets. At least one attachment is carried by the chain. The attachment is adapted to engage lengths of the sprinkler pipe whereby as the chain is advanced the length of pipe connected there is withdrawn from the field and carried onto the elongate framework.

Abstract: A meat grinder includes a bone chip remover in which the bone chips are removed at a radially outer region of the grinding plate through a single tangential opening substantially in the plane of rotation of the knife in response to intermittent operation of a valve. Knife blades which have substantial axial depth perpendicular to the plate are curved rearwardly to the direction of rotation, to apply an outward force component or pumping to chips which do not pass through the grinding plate, have terminal ends which sweep about a region radially outwardly of the perforated region of the plate, at a non-grinding or non-perforated region, behind which the chips are trapped and rotated about with the rotation of the knife blades for intermittent purging.
