      The several district courts of the United States are invested
    with jurisdiction to prevent and restrain violations of sections 1
    to 7 of this title; and it shall be the duty of the several United
    States attorneys, in their respective districts, under the
    direction of the Attorney General, to institute proceedings in
    equity to prevent and restrain such violations. Such proceedings
    may be by way of petition setting forth the case and praying that
    such violation shall be enjoined or otherwise prohibited. When the
    parties complained of shall have been duly notified of such
    petition the court shall proceed, as soon as may be, to the hearing
    and determination of the case; and pending such petition and before
    final decree, the court may at any time make such temporary
    restraining order or prohibition as shall be deemed just in the
    premises.
