Abstract: Impurities are removed from polythiophene by mixing a composition comprising polythiophene, water and an organic liquid at a temperature at which the organic liquid dissolves the polythiophene; allowing an aqueous phase to separate from an organic phase and recovering organic phase; adding water to recovered organic phase and mixing the resulting composition at a temperature at which the organic liquid dissolves the polythiophene; allowing an aqueous phase to separate from an organic phase and recovering organic phase; and allowing polythiophene solid to precipitate from recovered organic phase.

Abstract: Polythiophene may be processed using a method including providing a composition including the polythiophene and a liquid including at least one hydrocarbon having at least 6 carbon atoms; heating the composition to a temperature of at least about 50° C.; and separating solid polythiophene from the heated composition. Alternatively, the method may include providing a composition including polythiophene and an organic liquid; heating the composition to dissolve a portion of the polythiophene in the organic liquid; and separating solid polythiophene from the heated composition.

Abstract: A passive MMIC monopulse comparator includes a plurality of lumped element hybrids having pi and T filter structures. In one embodiment, a first hybrid receives first and second downcoverted signals and provides a first output signal to a third hybrid and second output signal to a fourth hybrid. A second hybrid receives third and fourth downconverted signals and provides respective third and fourth output signals to the third and fourth hybrids. The third hybrid provides sum and elevation channel signals and the fourth hybrid provides azimuth and G channel signals.

Abstract: A process for forming toner particles includes aggregating the toner particles by adding an aggregating agent to a latex emulsion of resin having a colorant mixed therein, the adding being done under adding conditions of agitation and a temperature above a glass transition temperature of the resin, wherein the adding of the aggregating agent comprises first introducing at least about 40% by weight of a total amount of aggregating agent to be added at a rapid introduction rate and subsequently adding a remaining portion of the aggregating agent at a continuous addition rate slower than the rapid introduction rate. The particles are subsequently cooled to a temperature below the glass transition temperature of the resin when particles have been grown to the desired size.

Abstract: A compact RF monopulse receiver circuit having a relatively low noise figure which is particularly useful for operation in the millimeter wave frequency range is described. The compact monopulse receiver finds use in small projectile and small missile applications. Also, a combination of transmit signal protection circuitry and receiver circuit architecture allows the RF monopulse receiver circuit to operate in a missile or other projectile which utilizes high RF power transmit signals. The RF monopulse receiver circuit can directly provide a radiation pattern for target detection and tracking or alternatively, the RF monopulse receiver circuit can function as a monopulse feed circuit which can be used, for example, in a quasi-optically fed reflector antenna.

Abstract: We have cloned and expressed the cDNA for human liver mevalonate pyrophosphate decarboxylase, an enzyme of the cholesterol synthesis pathway. This cDNA encodes a 400 amino acid protein (43 kDa) which resembles the coding sequence of an unidentified and incomplete open reading frame adjacent to the COQ2 gene of Saccharomyces cerevisiae. We also found an expression sequence tag clone made from human infant brain cDNA to be almost identical to our cDNA sequence.

Abstract: A wheel cover retention system (10) for use with motor vehicle wheels includes a plurality of lug nuts (16) and a wheel cover (12). Each lug nut (16) has a decorative outer surface (42) with a flange (36) and a driving head which includes wrenching flats (42). The driving head sustains installation torque required to fix the wheel (14) to a vehicle. An intermediate body portion (40) of the lug nut (16) is smaller in diameter than the flange (36) is disposed between the flange and an end of the lug nut. The wheel cover has a plurality of apertures (28) accommodating passage therethrough of the body portion of the lug nuts (16).

Abstract: An oarlock lantern holder device for use in mounting a lantern on a boat gunwale includes an elongated arm and a horizontal split-ring clamp for clamping and holding a lantern and connected to the arm. A vertical shaft portion of the arm is mountable to an oarlock of the boat gunwale for slidably and pivotably moving the arm relative to the oarlock and thereby mounting the arm, split-ring clamp and the lantern therewith for undergoing swinging movement between inboard and outboard positions relative to the boat gunwale.

Abstract: A capped wheel nut formed of a cap and a nut insert which, when engaged, rotate together such as for removably engaging a wheel to a threaded stud of a hub of a vehicle. The capped wheel nut is rotated by a standard tool which applies a rotational force to the cap. Should the cap become disengaged from the nut insert, then the nut insert may be rotated by a standard tool which applies a rotational force to the nut insert in the absence of the cap.

Abstract: A decorative capped wheel nut for holding a wheel on a motor vehicle where the capped wheel nut is exposed to view and to the enviroment. The nut has first and second ends, the first end to engage the wheel of the automobile, and a circumferential edge intermediate the first and second ends. The cap includes a side section to cover the sides of the nut insert and a top section, joined to the side section, to cover the second end of the nut insert. The opposite end of the side section terminates in a free edge, flare or flange which contacts the circumferential edge of the nut insert. The cap and nut inset are welded together at the contact between the circumferential edge of the nut insert and the free edge of the cap.

Abstract: In spraying liquid herbicides and insecticides, a predetermined dose is delivered in each operation of a dosing apparatus. The dosing apparatus comprises a piston-and-cylinder combination supported on a hangle. The piston is biased in one direction by a spring or by pressurized propellant, and movement of the piston in this one direction causes the liquid to flow into the cylinder through a check valve. Actuation of a trigger-operated valve releases pressurized propellant into the cylinder on the opposite side of the piston (or alternatively into an auxiliary cylinder) causing movement of the piston and discharge of the liquid through a second check valve and then through a spray nozzle. The dosing apparatus includes a portable backpack structure molded of a plastics material, and is especially suited for portable operation in remote locations. The backpack is formed with a reservoir for reagent and a compartment for removably holding a pressurized propellant container.

Abstract: An improved wheel nut for securing a wheel to a vehicle hub or the like and for retaining a wheel cover on the wheel. The wheel nut preferably includes a nut body and a cap secured to the nut body and an axial gap is provided between the end of the cap and a portion of the nut body. A retaining ring is provided in the axial gap and the retaining ring extends radially outwardly beyond the wheel nut for retaining a wheel cover against the wheel and for precluding removal of the wheel cover unless the wheel nut is first removed.
