Abstract: 837,755. Positive clutches. IRONRITE Inc. Aug. 15, 1958, No. 26371/58. Class 80 (2). [Also in Group VIII] A clutch for the rotation of an eccentric through 180 degrees comprises power transmission members 62, 63 which are movable into and out of driven engagement with eccentric 52 and a pair of control members 67, 74 coacting with said transmission members for controlling the movement thereof, one of said control members 67 moving first one and then the other transmission member out of a driven engagement and the other of the control members 74 being selectively adjustable between a pair of positions in one of which the transmission member, which is permitted by the first control member to be in driven engagement, is releasably held out of driven engagement and in the other of said pair of positions, said permitted transmission member is allowed to be in driven engagement, said other control member 74 moving both said transmission members out of driven engagement as it is adjusted from the second to the first of its two positions. Clutch assembly 20 comprises clutch body 49 on shaft 48 which has keyed thereto eccentric 52 and has stepped surfaces 51, 57, 58 and 59. In a pair of channels 61 slide a pair of keys 62, and 63 with projections 64 and 66. A cam ring 67 with a fixed leg 68 is mounted on surface 57 and has sharplyinclined cam surface 72 and gradually inclined surface 73. Mounted on surface 58 is a trigger ring 74 which is movable to the extent allowed by cut-out portion 76 and leg 68. It is also provided with a cam surface, similar to portion 69 of ring 67, which includes a ramp 78 and a " drop off surface " 79. Keys 62 and 63 are urged towards gear 41 by a spring plate 84 having leg portions 86 and 88. When trigger ring 74 is in the position shown in Fig. 11, key 63 is prevented from moving and engaging a notch on hub extension 47 by the surface of the trigger ring near " drop off surface " 79. When the trigger ring is momentarily moved to the position shown in Fig. 10, the key engages a notch and causes the rotation of the whole assembly including eccentric 52 but excluding cam ring 67 which is fixed, and trigger ring 74, the position of which controls the clutch. With trigger ring 74 restored to its original position, key 63 is brought out of contact with its driving notch and key 62 does not engage because it is held back by the trigger ring. However, if the trigger ring is maintained in the position shown in Fig. 11 the drive will be taken up alternately by keys 62 and 63. The control of trigger ring 74 may be by means of a spring-loaded shaft 94 (Fig. 7), while a second shaft 104 may control a conventional clutch operated by rod 127. Alternatively (Fig. 13), a single control rod 132 may have a radiallyextending pin 133 to operate trigger ring 74 while the other clutch is operated by a recess 131 acting in conjunction with rod 127.
Patent GB-832052-A (GB)
Title: Improvements in and relating to multistable magnetic core circuits
IPC: G11C19/04
Filed: 1958-08-18
Abstract: 832,052. Circuits employing multi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug.18, 1958 [Aug. 16, 1957], No. 26448/58. Class 40 (9). A magnetic core is connected to provide the feed-back path of a one-stroke blocking oscillator, the action of which is limited at each stroke by a delay line so that the core may be stepped progressively over equally-spaced datum states by a sequence of trigger pulses. In Fig. 2 a trigger pulse at 18 to the grid of triode 21a produces conduction in winding 25 of core 10 and feed-back over winding 32 to hold triode 21b conducting and maintain conduction in winding 25. After a predetermined time a delay line 40 inhibits triode 21 b to stop conduction. The core 10 can be shifted in this manner by as many pulses as are required to drive it to saturation at which point a positive-going voltage is set up in winding 62 to unblock a triode 50 which drives winding 16 and acts as a blocking oscillator limited only when the core 10 is driven to reverse saturation. Triode 50 therefore resets the core 10 after each full count. As shown in Fig. 4 pulses may be counted into core 90 and the count may be shifted backwards and forwards between core 90 and core 92. Each core is set to zero remanence by circuits 94, 96, and trigger pulses from a source 102 are counted. Each trigger pulse fires pentode 106 which sets off the limited blocking oscillator constituted by triode 120, windings 112 and 116, and the delay line 132. Ten pulses are required to move core 90, or 92, from its zero state and to drive it into saturation from its one state. Any particularl registration in core 90 may be counted out by a set of ten pulses on terminal A which over amplifier 140 takes the core 90 to saturation and thereafter, since no blocking voltage is induced in winding 146, opens up pentode 142 so that the remainder from 10, after having consumed the complement of the registration to 10, is fed over delay 144 and amplifier 145 to pentode 142 for registration in core 92 where triode 154, windings 148 and 152, and delay line 156, act as a limited blocking oscillator. Thus the registration in core 90 is erased and written into core 92. The process may be reversed simply by feeding the ten counting-out pulses to terminal B when core 92 is erased and its content given to core 90.
