Title: Device for search of information
IPC: G06F17/28
Filed: 1972-12-07
Abstract: 1420964 Information retrieval systems ASAHI KOGAKU KOGYO KK 7 Dec 1972 [7 Dec 1971] 56549/72 Heading G4A In an information retrieval system data is stored on a record medium in a storage assembly in for example alphabetical order, each data word having assigned to it a code indicating the number of the letter at which it differs from a preceding word and the different letter. If for example the word " abandon " is to be retrieved from recorded information including the following data list  a counter 3 is stepped to its " one " state and the first letter " a " of " abandon " is coded by a device 4 and entered into a register 7. A circuit 12 controls a comparator 5 so that when the counter is at a count of " one " or the storage assembly is at its starting position for any letter, if the contents of register 1 are greater or less than the count in counter 3 the storage assembly is advanced or returned by output (a) or (b) respectively. At equality output (c) activates comparator 6, outputs (d) or (e) of which advance or return respectively the assembly in dependence on whether the contents of register 2 is less than or greater than the contents of register 7. At equality output (f) stops the assembly. When the counter is at a count of two or higher and the storage assembly is not at its starting position the control for comparator 5 is reversed. If the assembly is initially at position 6 detectors supply signals representing 4 and s to registers 1 and 2 respectively. Comparator 5 controlled by the circuit 12 consequently initially advances the storage assembly until at position 8 equality is reached so that the control transfers to comparator 6. Since the contents of register 2 are greater than the contents of register 7 the storage assembly is then returned to its first position. Counter 3 is then stepped to a count of two and the second letter " b " of " abandon " is entered into register 7. The storage assembly is again advanced to position 2 when the equality signal from comparator 5 enables comparator 6 and since the contents of register 7 exceed those of register 2 the assembly is advanced to position 3 at which equality occurs. The third letter " a " is then entered and the counter stepped to 3. The storage assembly is again advanced, initially since the assembly is in its starting position for the letter and subsequently because the contents of register 1 exceed the contents of counter 3, until at position 7 control is transferred to the comparator 6 which returns the assembly to its starting position for this letter, i.e. position 3. The fourth letter " n " is then entered and the counter incremented. Comparator 5 advances the assembly to position 4, control then being transferred to the comparator 6 which advances the assembly to position 5 at which the word " abandon " is stored. Subsequent letters result in the assembly being advanced and then returned to position 5. The apparatus may also be used for searching items in the Japanese syllabary.

Abstract: 1455709 Automatic control of machining cycles SIEMENS AG 31 Dec 1973 [29 Dec 1972] 60191/73 Heading G3N In a numerical control system for controlling relative movement between a tool and a workpiece (in a deep drilling operation), the tool penetrates and retreats from the workpiece in a sequence of cycles (a, bc, d, ef), Fig. 2 (not shown), the infeed, for each cycle excluding the first, taking place initially at a rapid feed to a location adjacent the maximum excursion of the previous feed, followed by a machining feed for an incremental distance (Q), the machining feed at the last in-feed being terminated at the required penetration (BT). The first in-feed takes place at machining feed. At the commencement of each intermediate cycle, the content (Q) of increment register 8 receiving its content from tape reader 1 is added to the content of register 9, the latter having been counted up by the feed-out pulses from pulse source 3 during the previous cycle, the incremented count of 9 thus representing the depth of the next in-feed. The content of register 8 is marginally incremented (50 to 50.5) (Fig. 2) to provide a clearance, and infeed is instigated at rapid feed until, as detected by comparator 11, the content of register 8 exceeds that of register 9, the latter's content being decremented by the feed-in pulses also supplied to drive 6, whence, a signal from the comparator 11  being fed to source 3, further in-feed takes place at the machining feed, until a null content of 9 is detected by unit 12, whence after a pause, rapid out-feed is instigated. The in-feed pulses are counted by register 10, and, during the rapid out feed the content of register 10 is reduced by the out-feed pulses to zero, whence, via null detector 13, the out-feed is terminated, and gate 18 is opened to allow the count in register 9 to be incremented for the next cycle by the content of register 8, the latter having been reset to (Q) at the commencement of the out-feed. For the first cycle, in-feed pulses decrement register 2 until its content, detected by unit 5 is zero whence out feed takes place while register 9 is incremented by the out-feed pulses. After the first cycle, the decrement register 2 is set to the required penetration BT, the drilling operation being terminated by a final rapid out-feed subsequent to the attainment of zero by the register 2. A cycle store 4 is used when a repeated number of like holes are to be drilled. Registers 9, 10 may be set to count in either sense about a predetermined, non-zero number detected by units 12, 13.
