Abstract: 1,257,933. Luminescent screens. COMPAGNIE GENERALE D'ELECTRICITE. 3 July, 1969 [4 July, 1968], No. 33680/69. Heading H1D. A method of producing a c.r.t. screen for a colour TV receiver comprises depositing a layer of phosphor material (e.g. red emitting) which changes state on exposure to light and becomes fixed to the screen support surface, selectively shining a laser beam on the layer in predetermined regions to fix the material, washing to remove unfixed material and repeating for second and third phosphors (e.g. blue and green emitting). A mask is preferably used and with rectangular holes to produce phosphor strips. The laser may be stationary and the mask placed in different positions or the laser source shifted successively into positions corresponding to three electron guns. Also the laser source may be on one gun axis and two totally reflecting mirrors or prisms successively disposed on the other axes, and the reduced dispersion of the laser beam allows the mask to be spaced from the layer to avoid phosphor detachment. When a mask is not used, the laser beam may be focused to a spot which successively sweeps the strips to be illuminated.

Abstract: 1,264,546. Automatic control of rolling mills. WESTINGHOUSE ELECTRIC CORP. Feb. 21, 1969 [March 13, 1968], No. 9499/69. Heading G3R. In a multistand rolling mill gauge error is corrected at at least one of the stands in response to thickness measurements made after the last stand and also at a location which is before or after the first operative stand, the measurement made at said location being stored in a "profile memory" to allow for the transit time between stands of the material, in addition to which the roll force at at least one stand is measured, the unloaded opening at said stand is measured and controlled, and the speed of at least two stands is controlled. The invention is applied to a five stand cold rolling mill. As shown, gauge errors in the feed strip are substantially eliminated at stand 1, whose screwdown is controlled in response to the roll force detected at 30 by a system which includes a screwdown position detector 24. Remaining gauge errors are detected by an x-ray detector X1 and the signal from this adjusts the speed regulator Sl of stand 1 after a delay sufficient for the error to reach stand 2; this regulates the reducing effect of stand 2 by altering the tension of the strip entering it. X1 is sampled at a high frequency. The effect of a screwdown adjustment at stand 1 is checked periodically by the signal from X1 and if necessary this control loop is automatically re-calibrated by adjustment of its gain. Similarly, the effect of speed adjustment of stand 1 is checked by a second x-ray gauge X2 following stand 2 and the speed control signal is re-adjusted if necessary. This checking procedure compensates for changes in hardness of the stock. The thickness reduction effected by the mill as a whole is regulated by control of the strip tension between each stand. Detectors 28 control the screwdown of the next following stand in each case. This system automatically compensates for errors arising during acceleration and deceleration. Vernier control of the gauge at exit is effected by adjusting the speeds of stands 4 and 5 in response to a final x-ray gauge X5. In addition, the error signal from X5 is integrated over a predetermined period and the result used to change the set point of the screwdown and speed control systems of stand 1. "Head end" correction is effected by pre-programming the screwdowns and "tail end" correction by increasing the interstand tension by a predetermined amount as the tension on the input side of the preceding stand disappears. All controls are effected by a digital computer 40. In Fig. 2 (not shown) no control is effected at stand 1, the first correction being by adjustment of the screwdown of stand 2 in response to an x-ray gauge preceding it, the set point of which is recalibrated if necessary in response to a second gauge following stand 2.

Abstract: 1,264,945. Self-tuned circuits; interference suppression in radio receivers. SPERRY RAND CORP. 29 April, 1970 [16 May, 1969], No. 20652/70. Headings H3A and H4L. An automatic tuning apparatus for rejecting an interference signal comprises a filter 11 having an input terminal 10, output terminals 17, 18 providing band-rejection and band-pass output signals centred on the same frequency and tunable in unison over a frequency range and an arrangement 27 for determining the relative phase of the output signals to provide a control signal at 23 to tune the filter to the interference signal. The output signal at 17 may lead or lag the output signal at 18 by 90 degrees according to whether filter 11 is tuned above or below the frequency of the interfering signal. The output signals are phase compared in a J-K flip-flop type of detector 27, the detected output being integrated at 28 for varactor tuning of filter 11. When the integrated output has reached an upper outside limit, zener diodes Da, Db and diodes Dc-De in a drift-actuated scan circuit 31 will be conducting and the effect of voltages being applied to a NAND gate 54 and to the cross-coupled NAND gates 53, 55, is such as to produce a high output at a preset terminal 25 causing the Q output to switch to a low level so that the integrated output begins to decrease. As the integrated output falls, zener diode Da ceases to conduct and when a lower inside limit is reached, the preset terminal output is removed and the Q output is determined only by the signals present at J, K and clock pulse inputs. Similarly when the integrated output has reached a lower outside limit, due to the action of signals present at NAND gates 56- 59, a low level output is applied to the Q terminal switching the Q output to a high level so that the integrated output increases until an upper inside limit is reached when Q output is controlled only by the detector 27 input signals. In Fig. 3 (not shown) a plurality of filters (11, 41) are connected in cascade with the band-rejection output terminal of the last filter (41) connected to the clock pulse inputs of a plurality of J-K flip-flops (42, 27) whose steering inputs are connected to the band-pass output terminals of the filters, the phase detected outputs being integrated before application to the control inputs of the filters to tune each to one of a number of interfering frequencies.

Abstract: 1,265,014. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 22 Oct., 1969, No. 51786/69. Heading G4C. A digital data storage system comprises duplexed storage arrays 1A, 1B, a configuration shift register 15, and control means arranged selectively to render either or both storage arrays active or inactive in accordance with the contents of the configuration register. Fig. 1 shows two pairs of associative storage arrays 1A, 1B, and 2A, 2B, each pair as in Specification 1,265,013 which is referred to. Each array has a column of selector triggers, one trigger e.g. 10A or 10B per word location, the triggers of a given array being connected as a shift register so that their states can be shifted down one by a " next " operation. Each pair of arrays has a 2-bit configuration shift register 15 or 16 feeding both columns of selector triggers in common, the output of these columns of the first pair of arrays feeding the shift register 16 of the second pair. Input/output registers 5A, 5B, 6A, 6B, 7A, 7B, 8A, 8B link the arrays to buses 3, 4 as shown. The arrays of a given pair store identical data. Corresponding input/ output registers are continually compared, as are corresponding selector triggers, inequality producing an error indication. If a configuration control line 18 is not energized and both stages of configuration shift register 15 or 16 are " zero," the corresponding pair of arrays is isolated from the rest of the system and the connections between the configuration shift registers by-pass the columns of selector triggers in this pair of arrays. If control line 18 is not energized and both stages of the configuration shift register are " one," both arrays of the pair are in operation, whereas if only one stage is " one" the respective array of the pair is operative alone and this leads to an error indication from the comparisons mentioned. The first array of every pair, or the second array of every pair, or both, can be rendered inoperative (isolated) by de-energizing a first or a second of two configure lines or both of them respectively, during a diagnostic mode initiated by the error indication. In the diagnostic mode, the control line 18 can be energized to connect the configuration registers and columns of selector triggers into a single shift register as shown, preventing any by-passing of the selector triggers. Binary control data can be entered into the configuration shift register 15 at 17. The arrays may be non-associative.

Abstract: 1297565 Automatic exhange systems WESTERN ELECTRIC CO Inc 18 Feb 1970 [24 Feb 1969] 7803/70 Heading H4K A communication switching arrangement comprises two switching systems arranged such that when a given one of the switching systems completes a connection between a calling and a called subscriber the other subsequently operates to establish a further connection between those subscribers. As described on existing step by step exchange including line finder F, first selector SEL and connector C is extended by the inclusion of an electronically controlled exchange including a switching network 3, the latter exchange dealing only with video signals between subscribers with video telephone sets. The existing exchange is modified by the inclusion of converter trunks 4 and converters 1 which store and forward dial pulses of ordinary subscribers and which converts multi frequency signals from some subscribers (including those with video equipment) into dial pulse trains for use by the existing equipment. For a video call the calling subscriber dials a prefix code indicating that he requires a video connection and the number of the called subscriber. The called number is converted from multi-frequency to dial pulse form and used to step the first selector SEL and the connector C of the existing system. In the electronically controlled system a unit 6 recognizes the prefix code and sends an inhibit signal to the converter preventing the last dialled digit from being transmitted and preventing the audio path from being completed. The calling line circuit is identified by video control 2 by applying an identifying signal on leads T and R and scanning leads SC. the called time is determined by translation of the dialled designation and the called line is tested for busy-idle condition over leads TT-. If the called line circuit returns idle condition a free video path through the network 3 is selected under control of a store storing the addresses of the idle links, and a video path is established via the subscribers video line circuit. This connection causes both the video and audio time circuits of the called subscriber to be marked busy. The inhibit signal to the existing exchange is then removed causing the audio path to be established, the busy marking on the audio line circuit being removed by a timing circuit immediately prior to being required for the audio connection. After establishment of the audio connection the addresses of the two subscribers involved the video connection as given by the electronic equipment store are used to verify that the same two subscribers are connected over the audio path. This is effected by connecting a verify signal to the audio path and monitoring particular leads SC-.
