Abstract: Provided are methods for preparing a compound of Formula I: where the method comprises the steps of: contacting a compound of Formula II: with 1,3,5-benzene-tricarbonyl chloride in the presence of a polar aprotic solvent to form an amide adduct; and subsequently condensing the amide with a proximate anilino group present in the adduct in the presence of a condensing agent to form a compound of Formula I wherein R1, R2, Ar, m, p, and t are as defined in the specification.

Abstract: There are provided compounds of Formulae I and II: where: n is 1, 2 or 3; p is 0, 1 or 2; the sum of n +p is 3; R1 R2, R3 and R4 are each independently H, F, alkyl, trialkylsilyl, triarylsilyl, aryl or substituted aryl. R5 and R7 are each independently alkyl or aryl; and R6 is H or alkyl. R8 is H, F, or alkyl There are also provided electronic devices containing such compounds.

Abstract: An automated tubular running tool for use in drilling systems and the like allows for the picking up, positioning, stabbing and threadedly connecting a tubular segment to a tubular string being held by the rig by a spider. The tool comprises a pivoting arm, which can pickup, position, stab and threadedly connect the tubular segment. The tool further features an integral elevator, which then lowers the piping string tubing string into the well bore. This tubular running tool allows for the connection of tubular segments to a tubular string without the need of personnel.

Abstract: A pick-up and lay-down pipe handling system and method providing a telescopingly extendable crane boom which transports tubulars and pipes both linearly and vertically. The crane boom is preferably pivotally moveable with respect to its base and the crane may be able to rotate with a 360 degree range of rotational movement with respect to the base. The crane boom employs a cable or plurality of cables that run between at least two winches at the base of the crane boom. The cables are run through two pulleys or carriages attached to a hollowed out half pipe section into which the tubulars or pipes are placed. The winches are then activated to move the hollowed out half pipe both vertically and linearly to the desired position.

Abstract: The present invention relates to charge transport compositions. The invention further relates to electronic devices in which there is at least one active layer comprising such charge transport compositions.

Abstract: Random, melt-processible copolyimides are disclosed herein. These copolyimides are semicrystalline and exhibit recoverable (semi)crystallinity from their melts. Associated processes, which entail either solution polymerization or melt polymerization, for producing and fabricating these copolyimides into useful articles having a predetermined shape are also disclosed.
