Abstract: A vibration absorbing support comprising a base having an upstanding post and a concentrically arranged flange surrounding the post with radially extending upstanding ribs therebetween. An annular elastomeric bushing is slidably fitted between the post and the flange and rests on the ribs. The bushing supports a base for a vibrating apparatus in such a manner that the elastomeric material is subjected to a shearing force in a vertical direction and a compressive force in a horizontal direction to permit a maximum amplitude of movement vertically and a restricted horizontal movement.

Abstract: A paper feed device for data printers in which the paper is pushed endwise through a guide channel past the printing station to line space the paper. In order to adequately space the paper to a position where the last printed amount can be read by the operator and to insure consistent line spacing, it is first retracted an amount equal to one line space plus a fraction thereof and is then pushed endwise in an advancing direction an amount equal to such fraction to correct for backlash in the paper drive mechanism and to compress the paper within the guide channel. Following printing, the paper is further advanced by an amount equal to two line spaces to enable the newly printed amount to be visible to the operator. When it is desired to double space the paper, the retraction thereof is limited to an amount equal to such fraction.
