    摘要： A tape transport assembly employing a belt drive for the tape comprises:A. a pair of reels for tape to be transported from a supply roll on one reel to a take-up roll on the other reel,B. an endless belt located to arcuately engage the tape rolls on the respective reels for rotating the rolls and reels to effect said transport in response to endwise travel of the belt, andC. support means for supporting the reels and belt to accommodate bodily displacement of at least one reel relative to the belt into and out of position in which the tape roll on said one reel arcuately deflects and engages a first section of the belt.

    摘要： A method of adjusting stimulation amplitude in continuous ink jet printers to provide satellite-free printing includes the steps varying the stimulation amplitude between the underdrive and overdrive stimulation conditions, charging the resulting ink jet filaments at their break off points with sawtooth voltage of period equal to the stimulation period, detecting and storing the resultant drop charging events and setting the operating stimulation amplitude based on the inception point inflection in the resulting stimulation amplitude versus detected charge relation.

    摘要： A tape transport assembly typically employing a belt drive for the tape comprises:A. a pair of reels for tape to be transported from a supply roll on one reel to a take-up roll on the other reel,B. at least one peripheral support to peripherally engage one of said reels to position same upon initial reception thereof in said assembly, andC. centering support means carried by the assembly for relative movement into and out of centrally supporting position in which said one reel is displaced out of peripheral engagement with said peripheral support and is centrally supported for rotation.

    摘要： A leader strip is connected with a tape at one end of the tape; and the leader strip has characteristic lengthwise unit bending stiffness which is substantially greater than leader characteristic widthwise unit bending stiffness. Further, the overall width of the leader typically exceeds the overall width of the tape, and the edge portions of the leader are engageable with non-grooved inner walls of reel flanges to be frictionally retained in position between the inner walls. A magnetic tape transport is provided with two such reels between which the tape and leader are transported.
