Abstract: 1314796 Threading record tapes HONEYWELL INFORMATION SYSTEMS Inc 19 April 1971 [20 April 1970] 20540/71 Heading G5R A free end 2À81 of tape on a supply reel 2À1 rotating in a take-up direction is detected by sensing means 2À9, 3À12 which thereupon initiate a sequence of operations beginning with the reversal of the rotation of the reel 2À1 so that the free end 2À81 of the tape is thrust into guiding means which conduct it towards a take-up reel 2À3, past a magnetic head 2À7. As shown, angled air jets 2À26 assist the passage of the tape until it is captured by suction applied to holes 2À4 in the hub of the take-up reel 2À3, which is then driven in response to the operation of a second pneumatic sensor 3À21. (If the sensor 3À21 has not operated after 1À5 seconds, the system is stopped). After a predetermined time, the drive to the take-up reel is reversed and the supply reel drive is resumed, so that both reels pay out tape into vacuum buffer chambers 2À24, 2À25 while a vacuum brake 2À8 engages the tape between the buffer chambers. Pneumatic tape-loop sensors in the buffer chambers finally operate to stop the threading operation. During rewinding, sensor 3À12 responds to the passage of the end of the tape past aperture 2À10 and switches off the tape drive. Retractable tape-cleaning blades (30, 31), Fig. 1 (not shown), are mounted in the tape guides 2À5, 2À6.

As shown, a disc harrow is provided with a hydraulic cylinder 41 connected by links 46, 47, 48 to transverse portions of cranked axles 34 for raising and lowering the discs 26. The cylinder 41 is provided with a valve 59 normally maintained open by a spring 63, the plunger 58 of the valve being connected by a cable 67 to a chain 68, the links of which are selectively locked in a yoke 70 by the tractor operator through a cable 73. The cable 67 is trained over a pulley 65 mounted on a bracket 64 connected to the plunger 45 of the piston 44. Oil is fed into either end of the cylinder 41 through hoses 54 and 50 under the control of valve mechanism on the tractor. When the chain is locked in position and oil is pumped through hose 50 the movement of the piston 44 causes the cable to tighten and close valve 59, the pressure building up behind the valve causing it to close before the cable is fully taut. The oil in the cylinder is locked in position and the tools are raised by pumping oil through hose 54 to open valve 59. The stroke of the piston is adjusted by altering the position of the chain in the yoke 70 which causes the valve 59 to close at a different position in the stroke of the piston.
