Filed: 1971-11-04
Abstract: 1361660 Digital control of information stores FUJI PHOTO FILM CO Ltd 4 Nov 1971 [4 Nov 1970] 51436/71 Heading G4H In a micro-film storage system where microfilm frames are arranged in at least two coordinates on the storage medium, an input number of a desired frame is converted into coordinate reference signals to operate a mechanism to select a desired frame for viewing. In one arrangement where a number of micro-film sheets each contain a two dimensional array of micro-film frames, the index number of a desired frame is manually keyed into a register and compared with the succession of frame index members read from an optical disc store or magnetic tape store. A clock pulse is generated for each input number read and which pulses clock on an X-co-ordinate counter, whose carry signal clocks on a Y-co-ordinate counter, whose carry signal clocks on a Z-co-ordinate counter. The clocking is stopped upon a comparison being found between the index numbers, whereby the output of the three counters indicates the co-ordinate position of the desired frame and operates a mechanical selector mechanism or alternatively an optical selector mechanism, e.g. CRT.
Patent GB-1141336-A (GB)
Title: Improvements in or relating to memory systems
IPC: G11C11/06
Filed: 1966-11-17
Abstract: 1,141,336. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORP. 17 Nov., 1966 [6 Dec., 1965], No. 51468/66. Heading H3B. A write or read current passed in a given direction through a selected drive line 24-27 of a magnetic storage matrix 10, Fig. 1, is distributed between and passes through all the other parallel drive lines in the reverse direction. A three co-ordinate store is shown having X drive lines 24-27, Y drive lines 28-31, a sense line 12<SP>1</SP> for each storage plane 12, 14, 16 and inhibit lines (not shown). Each parallel drive line is connected to a respective gate G which applies a positive (up) potential when either one of the two inputs " X address select " and " read/write " is present at respective terminals 43-46 and 48, and applies a negative (down) potential when both inputs are either simultaneously present or absent. For a read/write cycle to take place a transistor 52 is rendered conductive by a driver gate signal at terminal 58, and at the same time an X address select input is applied to a selected G gate 38-41. During the read portion of the cycle an input is applied to the read/write terminal 48 so that the selected G gate connects a " down " potential to the associated drive line 24-27. The remaining gates apply " up " potentials to their respective drive lines as they have but one input, and read current passes through the selected drive line by way of a circuit comprising all the unselected drive lines and their associated diodes 70-73 in parallel, transistor 52, and the diodes 74-77 connected to the selected drive line. The write portion of the cycle is characterized by removal of the read/write signal from terminal 48 so that the selected G gate now applies an " up " potential and the remaining gates connect a " down " potential, the direction of current through all the drive lines being then reversed. A single G gate is shown in Fig. 3 and comprises two transistors 84, 86 connected in series with a drive line 24 connected to their common connection. Normally transistor 84 is non- conducting and connects positive potential to the drive line through conducting transistor 86. If either of the X address select or read/write inputs of an exclusive OR circuit 80 are applied, the G gate output condition is maintained by inversion at 82 of the exclusive OR gate output. When, however, both exclusive OR gate inputs are simultaneously present or absent, the inverted output causes transistor 84 to conduct thereby cutting-off transistor 86 and applying ground potential to the drive line. It is stated that the distributed reverse currents applied through unselected drive lines minimize noise.

Title: Ultrasonic inspection system for materials
Inventor: GIBBS HAROLD
IPC: G01N29/06
Filed: 1966-11-22
Abstract: 1,147,089. Ultrasonic inspection devices. NATIONAL RESEARCH DEVELOPMENT CORP. 21 Nov., 1967 [22 Nov., 1966], No. 52169/66. Heading H4D. In an ultrasonic pulse-echo inspection system a plurality of transducers including at least one shear-wave transducer, scans a workpiece in a zig-zag scanning pattern and received echoes are gated with respect to time and recorded. For inspecting butt or fillet welds transmitting/ receiving transducers 1, 2, 3, 4 are floatmounted on slide 5 which is reciprocated by pneumatic cylinders 6 in carriage 7, and carriage 7 is provided with pneumatic cylinders 10 and pneumatically-operated clamps 9 which, with cylinders 6, are operated in sequence so that the carriage is stepped along guide rails 8 tempor. arily fixed to the workpiece, whereby the transducers follow the scanning pattern shown along the weld run. Transducer 1 transmits and receives compressional wave pulses (e.g. two or three cycles of 2À5 to 5 Mc/s. carrier at a repetition rate of 2000 per sec.) and the received pulses are applied via a swept gain amplifier and preset time gate to a C.R.O. display and to a first recording channel of a high-speed pen recorder. This channel also receives signals indicating the transducer position and provides a plan position indication of the weld edges and any flaws. The transducer 1 signals are also applied to a second recording channel (and the C.R.O. display) via a strobing flaw gate which scans (e.g. at 25-50 times per sec.) the time period in which echo pulses are expected to arrive, to determine the arrival times of the echo pulses and thus to provide a recording of flaw depth in the workpiece. The first and second channels thus provide a three-dimensional record of the weld region. Transducers 2 and 3 each transmit and receive shear waves at a selected angle with the workpiece surface and are directed towards each other for detecting flaws extending normal to the surface. They are pulsed alternately to reduce cross-talk (but some cross-talk is retained as a check that both transducers are coupled acoustically to the surface) and are connected as in the second channel, via strobing flaw gates to third and fourth recording channels. Transducer 4 transmits and receives shear waves at an angle of 45-70 degrees to the surface along the line of the weld to detect transversely-extending flaws and is connected via a strobing flaw gate to a fifth recording channel. Actuators 11 and switch 12 provide locating markers on the recording. Additional transducers 13 may be mounted on carriage 7. When inspecting butt welds transducer 1 and the first and second recording channels need not be used.
