Abstract: 1,232,665. Stepping mechanisms, clutches; torque amplifiers. INTERNATIONAL BUSINESS MACHINES CORP. 7 Oct., 1968 [16 Oct., 1967], No. 47367/68. Headings F2L and F2X. A stepping mechanism comprises an output shaft, a drive shaft arranged in operation to be continuously rotating, a clutch arranged operatively to connect the output and drive shafts, an electrical stepping motor and actuating means controlled by the stepping motor for operating the clutch. A continuously rotating drive motor drives a pulley 1, Fig. 1, fixed to a sleeve 2 which is mounted on output shaft 4 by a sleeve 3. A helical clutch spring 7, rigidly secured with clamp 8, surrounds but is normally disengaged from sleeve 2 and has its end secured to a gear 9 meshing with a gear 10. The latter mounts a pawl 12 engaging a stationary ratchet wheel 13, the pawl being lifted out of engagement by the stepping motor 17 through a linkage 14. The stepping motor control includes a pulse generator (20), Fig. 3 (not shown), comprising a motor (21) driving a soft iron disc (22) with projections which pass along a pulse exciter 23 consisting of a coil wound round a permanent magnet to generate pulses which pass through a counter-controlled gate (24) to motor 17. Operation.-A pulse applied to the stepping motor 17 causes one step (clockwise in Fig. 2 (not shown)) to lift pawl 12 out of engagement with ratchet wheel 13. The load applied by clutch spring 7 rotates gears 9 and 10 until stopped by the re-engagement of pawl 12 with ratchet wheel 13. The rotation of gear 9 causes the windings of clutch spring 7 to diminish thereby gripping sleeve 2 which drives the output shaft 4. The re-engagement of pawl 12 and consequent detention of gear 9 and the end of clutch spring 7 fixed thereto causes the inertia of the drive shaft 4 to open the windings of clutch spring 7 to render the clutch inoperative. A spring clutch 18 counteracts reverse motion of shaft 4. The position of shaft 4 when held can be adjusted by movement of a segment 26 secured to the ratchet wheel 13. In another embodiment a pulley 101, Fig. 4, pressed on a bushing 102 is supported by bushings 103 on the output shaft 104 which has a bushing 105 secured thereto. A clutch spring 107 which is clamped to bushing 105 embraces bushing 102 and is surrounded by a body 109. The latter is attached to gear 109 by screws to provide adjustment for the position of shaft 104 when held. Bushing 105 and gear 109 have interengaging claws with a clearance which controls the maximum unwinding angle of the spring 107. The remaining parts function similarly to the corresponding parts of Fig. 1.

Abstract: 1295016 Master-slave bi-stable ITT INDUSTRIES Inc 6 May 1971 [13 May 1970] 13465/71 Heading H3T In a master-slave bi-stable circuit, crosscoupled transistors T3, T4 and T1, T2 form the slave and master bi-stables respectively, and coupling transistors T5, T6 have their baseemitter paths in parallel with the base-emitter path of a respective "slave" transistor, and their collectors connected to the collector of a respective "master" transistor, the emitters of the transistors T3-T6 being connected to a common input terminal E. Resistors R1-R4 may be replaced by current sources and R1 and R2 are preferably lower in resistance value than resistors R3, R4. With transistors T2 off and T1, T3, T5 on, an input pulse of 0.7 volts applied at E causes the emitter voltage of T3 to rise while its base is held at 0.7 volts relative to the negative line by the collector-emitter saturation voltage of T1 (0À1 volts) and the base-collector forward voltage of transistor T5 (0.6 volts). This causes T3, T5 to cut off and thereby T4, T6 to turn on. Reduction of the input pulse to zero volts relative to negative line causes T6 to shunt transistor T2, causing T1 to turn off and T2 on. The base of transistor T4 is now maintained at 0.7 volts as was that of transistor T3 so the next pulse at E causes T3, T5 to turn on and T4, T6 to turn off. Removal of the pulse then causes T1 to turn on at T2 to turn off. The circuit thereby switches state every alternate falling edge of the input pulses. The bi-stable circuit may be used in computer stores, shift register frequency dividers in wrist watches &c
