The polyimide has recurring units of the following formula (I):                                                (1) wherein X is a radical selected from the group consisting of a bond, divalent  hydrocarbon  radical  having  from  1  to  10  carbons, hexafluorinated isopropylidene radical,  carbonyl radical, sulfonyl radical and thio radical, and each nitrogen atom of imide ring is located simulatineously at meta- or para-position to ether linkage The polyimide of this invention is prepared by reacting 4,4'-(p-phenylenedioxy)diphthalic dianhydride with an ether diamine having the following general formula (V):                                          (V) and successively imidizing the resultant polyamic acid.       Examples of the ether diamine used for preparing the polyamide include, 2,2-bis[4-(3-aminophenoxy)phellyl]propane, 2,2-bis[4-(4-aminophenoxy)phenyl]propane, 2,2-bis[4-(3-aminophenoxy)phenyl]-1,1,1,3,3,3-hexafluoropropane, 2,2-bis[4-(4-aminophenoxy)phenyl]-1,1,1,3,3,3-hexafluoropropane, 4,4'-bis(3-aminophenoxy)biphenyl, 4,4'-bis(4-aminophenoxy)biphenyl, bis[4-(3-aminophenoxy)phenyl] ketone, bis[4-(4-aminophenoxy)phenyl] ketone, bis[4-(3-aminophenoxy)phenyl] sulfide, bis[4-(4-aminophenoxy)phenyl] sulfide, bis[4-(3-aminophenoxy)phenyl] sulfone and bis[4-(4-aminophenoxy)phenyl] sulfone.                       BACKGROUND OF THE INVENTION       The present invention relates to a novel polyimide and more particularly to the polyimide which is almost colorless, capable of being extrusion or injection molded and is furthermore excellent as high-temperature adhesive.      Conventional  polyimide  obtained  by  the  reaction  of tetracarboxylic dianhydride with diamine has excellent electrical and mechanical properties  in addition  to its good high-temperature stability.  Therefore the polyimide has been used in many fields such as electric and electronic members, space and aeronautic materials and

Abstract: ABSTRACT   A ceramic-reinforced aluminum matrix composite is formed by contacting a molten aluminum-magnesium alloy with a permeable mass of ceramic material in the presence of a gas comprising from about 10 to 100% nitrogen, by volume. balance non-oxidizing gas, e.g., hydrogen or argon.  Under these conditions, the molten alloy spontaneously infiltrates the ceramic mass under normal atmospheric pressures. A solid body of the alloy can be placed adjacent a permeable bedding of ceramic material, and brought to the molten state, preferably to at least about 700°C, in order to form the aluminum matrix composite by infiltration.  In addition to magnesium, auxiliary alloying elements may be employed with aluminum.

Granted: 1991-02-12
Abstract: Mistie Detector and Indicator System Abstract of the Disclosure A knotter mechanism, utilized on a square baler to encircle the bale with a wrapping material and tie a knot in the material after the wrap is complete, is provided with a detector mechanism for detecting knotter malfunction.  The detector mechanism comprises an elongated detector pin which is mounted to pivot in a vertical plane, the pin being mounted on the twine finger of the knotter mechanism 80 as to pivot therewith in a horizontal plane.  The pin is encircled by the wrapping material as the bale is encircled and is within the loop of wrapping material after a knot is tied.  As the tied bale is moved rearwardly from the knotter station the detector pin engages the loop of wrapping material and pivots the twine finger thus causing a switch to be actuated.  Failure to actuate a switch signals a knotter failure,  Upon further movement of the tied bale rearwardly, the loop of wrap material slips over the end of the detector pin and a spring mechanism returns the twine finger and the pin to their initial position.

Abstract: ABSTRACT OF THE DISCLOSURE           An optimization method of dressing a predetermined profile on the periphery of a grinding wheel of the type used in form grinding. A dresser is guided along a path corresponding to the predetermined grinding wheel profile in successive, identical cycles of motion.  The grinding wheel is fed into the path in increments between cycles.  The dresser contacts the periphery of the grinding wheel during movement along its path, with the duration of contact increasing in each cycle until the predetermined profile is produced.  The duration of contact during each cycle is monitored.  When the difference between the duration of contact in a given cycle and the duration of contact in the previous cycle is zero or negligible, dressing is complete.

Abstract: Methods and apparatus are provided for applying a colorant material to the surface of a plastic insulation material which has been applied to an elongated material such as a metallic conductor or an optical fiber which is being moved at any of a wide range of speeds along a path of travel. The colorant material is applied by nozzles which are staggered along the path of travel and which directthe colorant into engagement with the plastic insulation material at different radial directions. A first plurality of nozzles each cause the colorant to be in a spray pattern which is in the area of a plane. Advantageously, those nozzles cooperate to stabilize the conductor and prevent undulations thereof as the conductor is moved along its path of travel. A second plurality of nozzles cause the colorant to be in a solid conical pattern. The first and the second pluralities of nozzles are effective to cause substantially all the surface area of the plastic insulation on successiveincrements of length of the conductor to be covered with the colorant material.
