Patent GB-1275310-A (GB)
Title: Combined display system and circulating memory
IPC: G06F3/153
Filed: 1969-09-22
Abstract: 1275310 Circulating memory for use with a display system RCA CORPORATION 22 Sept 1969 [27 Sept 1968] 46468/69 Heading G4C The invention relates to the synchronization of signals between a circulating memory and a display device. Data is recirculated in a magneto-strictive delay line which may be subject to drifts, and is displayed on a CRT. The CRT displays 16 rows each containing 32 character bits and each row stored in the memory is accompanied by a control character. As described the memory feeds two separate CRT's and contains 1056 characters each as an eight bit code, seven information bits and a parity bit. A character occupies a time of about 10 Ásecs. in the memory. Data DL2D is fed from the delay line via NAND gate 10 to register 500 containing four flip-flops and is advanced by a signal DQ-1 having eight pulses per bit time so that for a "1" at the NAND gate the register will successively store 1000, 1100, 1110, 0111, 0011, 0001, 0000, since each one bit lasts 0À5 Ásecs. i.e. for three pulses of DQ-1. Three of the flip-flops feed a flip-flop 68 via invertors 20, 56, NOR gate 58, AND gates 60, 64, 66 and flip-flop 62 such that during an 0À5 Ásec. pulse DLC4 (Fig. 6) the flip-flop will be set during time interval t8 (Fig. 6) of the same or following bit period regardless of the time of entry of a "1" bit and the following bits will be synchronized with the following t8 periods. (This assumed that there is no drift of one character relative to the next). Synchronized data from flip-flop 68 is entered into register 75 and shifted by DLC1-N occurring once per bit time. Two of the flip-flops of the register are arranged to feed a shift register arranged to hold a row of characters, the register being divided into two halves to hold the odd and even bits respectively, entry being controlled by a flip-flop 72a, Fig. 3, set or reset according to whether the first two bits are read into the register during the second or the third bit time. When the register is full the contents are fed to a character generator feeding the CRT and the contents are recirculated in the register at high speed and fed back to the delay line coincident with the start of a scan line. The data is read out over a period occupying 5¢ TV scan lines, a half-scan-line pause occurs, and the recirculation occupies one scan-line period. A row of characters occupies 14 scan lines, the first two and last two of which are blank to form a space between rows. The data is returned to the delay line under the control of a master timing circuit.

Filed: 1974-10-31
Abstract: 1456774 Magnetic bubble switching SPERRY RAND CORP 31 Oct 1974 [9 Nov 1973] 47163/74 Heading H3B In a magnetic memory bubbles are transferred between a major and plural minor loops by two magnetically soft linking elements D, E and a serpentine transfer conductor B which contacts once each soft magnetic element that it crosses. The bubbles are propagated by an in-plane rotating field H R  which normally drives bubbles leftwards across T and I bars A-G forming part of the major loop but may be transferred to minor loops formed by H and I bars such as H-J by the application of a current pulse to the conductor when the field H R  is between compass positions 3 and 4 to switch the bubbles to element D. Similarly, bubbles are switched back to the major loop by element E when a current pulse is applied at the time H R  is between positions 1 and 2. The conductor is of gold electrodeposited directly over the elements.
