Patent GB-721180-A (GB)
Title: Improvements in or relating to binary digit storage devices and register for digitalinformation
IPC: H03K23/82
Filed: 1952-08-28
Abstract: 721,180. Digital electric calculating apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 28, 1952 [Nov. 23, 1951], No. 21640/52. Class 106 (1) A binary digit storage device adapted to store only a single pulse at a time, comprises a pulse delay circuit having input and output terminals with means for producing a given time delay arranged between them, and is characterized in that means are provided for applying a delayed output pulse to the input terminals whereby the presence of the repeatedly delayed pulse is indicative of the digit stored therein. A plurality of delay elements 10 ... 14, each connected to the ganged movable arms 21 ... 25 of five-position switches 16 ... 20, serve simply as storage devices for binary digits when the switch arms are in the " A " position, each digit representation circulating in its own system under control of a source of pulses 15. In the " B " position of the switches the binary pattern is moved one step towards the left during each pulse cycle. In position " C " a multi-digit binary number can be entered into the storage in parallel form via terminals 28 ... 32. The data may be read out in parallel form during a single cycle by connections at jacks 35 ... 39. In position " D " of the switch the pattern is stepped along towards the right. Position " E " provides a complete break in each digit circuit for clearing the store in one pulse cycle. The rotary switches are merely symbolic and would, in an actual embodiment, be replaced by static electrical switching devices such as crystal diode gating matrices 47 ... 50, Fig. 2. A switching and delay unit 41 is adapted to handle four binary digits representing one decimal digit. When one of the terminals 43 ... 46 is brought from a normally negative potential to earth potential the effect is similar to a setting of the rotary switch as described above. For example, when terminal 43 is brought to earth potential, the apparatus is conditioned for shifting stored data to the right. Positive pulses at any or all of input terminals 51, 54, 57 and 60 are permitted to pass through switches and cathode-follower stages 47 ... 50 to delay elements 63 ... 66 of the type described in Specification 719,418 [Group XL (c)], in which a capacitor 80 is successively charged and discharged following the application of a pulse to the input terminals. The pulses reappear in the next succeeding time interval at the appropriate output terminals 67 ... 70 and pass on to the equivalent circuits in unit 42. For the operation of clearing the data from the register all the terminals 43-46 are kept at a negative potential.

Filed: 1928-07-26
Abstract: 321,156. Tomlinson, A. V., (McKenzie & Holland (Australia) Proprietary, Ltd.). July 26, 1928. Signals and points, interlocking. -In a points detector in which indicating relays are disconnected and shortcircuited if unauthorized movement of either of the tongues or the lock rod occurs, each tongue is linked by a crank 12 and a spindle 13 to a spindle 19 carrying a pair of cams 20, each of which controls by a pivoted lever 22 a resilient contact member 30 co-operating with a fixed contact 32<a>. Each cam 20 is secured to an arm 23 by a bolt 25 passing through an arcuate slot 24 and each pair of cams is so mounted that when their spindle 19 is rotated to either of its extreme positions, a terminal recess 21 on one cam permits the corresponding lever arm 22 to occupy its lower position while the recess on the other end of the other cam fulfils a similar function in the other extreme position of the spindle 19. An insulating block 29 carrying contacts 28 resting on the levers 22 is mounted on two adjacent resilient members 30 so that when a roller 26 engages its cam recess the associated contact 30, 32<a> is closed. When the rollers 26 ride on the high part of the cams 20 the resilient members 30 are raised and contact with a strip 43 which short-circuits the relay. When lock rod detection is also required each block 29 is fitted with a roller 33 riding on a cam 34 carried by a shaft 35 which is operated by a cam slot in the lock rod. This slot is of such a contour that the first motion of the point lock plunger before the points are unlocked causes the shaft 35 to rock from one side to a mid-position and so cause the cams 34 to raise the resilient members 30 until the plunger has again locked the points in the reverse position. An additional spring contact 37<1>, controlled by a cam on the shaft 35, controls a circuit for supplying power to operate the points. The bracket 14 and the spindle 13 are reversibly connected to the case and spindle 19 respectively for right and left hand layouts.
