  • ADJUSTING DEVICE
    Publication number: 20070138814
    Abstract: An adjusting device (1) may include a base (2), a rotary pin (6) rotatably positioned within the base (2), a latch recess (13) formed in the rotary pin (7), a latch body (12), a spring (10); and, a mounting bracket (7) adapted to pivotably hold and position an associated fitting to the rotary pin (6). The spring (10) urges the latch body (12) into the latch recess (13) and thus urges the rotary pin (6) and the associated fitting into a latched condition.

  • Preparation of N-phenyl-1-naphthylamine
    Patent number: 6133480
    Abstract: N-Phenyl-1-naphthylamine can be prepared by reaction of aniline and 1-naphthylamine in the liquid phase at 100-400.degree. C. under normal pressure, a catalyst mixture comprising boron and fluorine being employed. Such catalyst mixtures can be obtained, for example, by reaction of hydrogen fluoride, boric acid and aniline and/or 1-naphthylamine. The catalyst is recovered and can be employed again. The reaction can be carried out discontinuously or continuously.
