Abstract: Apparatus for enabling a user to selectively defeat the toll-call restriction system. The apparatus is comprised of means for applying a tone to the telephone lines through the calling telephone mouthpiece. Detection means responsive to the tone sets a flip flop which functions to inhibit the activation of a relay normally used to disrupt the connection between the calling phone and telephone lines when an unpermitted telephone number is dialed.

Abstract: An impact printer including a type bearing drum mounted for rotation about the axis of the drum and including a plurality of hammers mounted with the impact faces thereof opposed to the drum and aligned in a direction extending parallel to the drum axis. Raised characters formed on the drum surface are oriented so that a line extending from top to bottom of the character is parallel to the drum axis. As a consequence, as the drum rotates through one revolution, the hammers can be selectively impacted against the drum to print a complete column of text on a paper web therebetween. Since the characters move past the hammers along a horizontal line of text, excellent vertical registration of the characters in a line is assured.
