Title: Data transmission system
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: H04L12/02
Filed: 1960-11-15
Abstract: 968,279. Telegraphy. STANDARD TELEPHONES & CABLES Ltd. Sept. 29, 1961 [Nov. 15, 1960], No. 39143/60. Heading H4P. In a telegraphy system; a sequence of characters, occurring at random in the text of a message to be transmitted, which is identical to part of the sequence used for the " cancel " instruction, is recognized at the transmitter and causes the signals transmitted to be modified so as to prevent unwanted mutilation of the text at the receiver. In one of the described systems the " cancel " instruction comprises the sequence KKKKLLLL, and following the transmission of the sequence KKKKLLL from the text, a true " cancel " signal is transmitted which causes the receiver to cancel the last four characters received, i.e. KLLL. The transmitter then repeats these four characters and continues transmitting from the text. In this way a simulated " cancel " signal is split up and no unwanted mutilation results. A circuit for recognizing the first seven characters of a simulated " cancel " signal is shown in Fig. 2. Gates G1.1-G15 restore trigger T1 to the " 0 " state if a transmitted character is not a K, counter 7 being stepped on for each successive K transmitted. After four successive K's have been detected counter 7 selects gates G2.1-G2.5 which cause the counter to be stepped on for each successive L transmitted. In the other system described the " cancel " signal comprises the sequence XXYY, and if the sequence XXY is detected in the text the next character is deliberately mutilated before transmission. This mutilated character is detected at the receiver or transmitter and the latter then transmits a true "cancel " signal followed by a repetition from the text, the first character of the repeated sequence being the character previously mutilated.

Filed: 1958-12-04
Abstract: 912,463. Radar. RANK-XEROX Ltd. (Haloid Co.). Dec. 4, 1958, No. 39192/58. Class 40 (7). [Also in Group XL (b)] Electrical signals representative of intelligence to be displayed visually (e.g. in the computer, television and radar arts) are employed to produce an electro-static charge image on a sheet of insulating material which is then rendered visible and, if desired, made permanent. The signals, which consist of sequentially available " bits " of information in successive groups, corresponding to successive lines of the image, each group being preceded, by a synchronizing signal, are fed to an analyzing circuit 12 (Fig. 1) from which the " bits " are supplied to individual ones of a plurality of discharge electrodes 14 which, in co-operation with an earthed electrode 16, set up an electrostatic charge pattern on a web 15 of insulating material. Before the latter reaches the region of the discharge electrodes it passes through a housing in which a uniform charge pattern is established by means of radio-active source such as polonium (Fig. 4, not shown). The web which is advanced in the direction of the arrow at a rate determined by the synchronizing signals so that successive groups of " bits " produce successive lines of the charge image, then moves past a powder cloud (or equivalent) " developer " means 17 which produces a visible display 18. When a permanent record of the display is required the web 15 is then passed between heated rollers (Fig. 4, not shown). The analyzer 12 may employ gating means controlled via a tapped delay line (Fig. 2, not shown) or a ring counter (Fig. 3, not shown) by information " bit " signals and the synchronizing signals to effect the required distribution of the " bit " signals to the discharge electrodes. Alternately, the " bit " signals may be supplied directly to the discharge electrodes from individual taps on the delay line and the synchronizing signal supplied to the electrode 16 (which is now earthed via a high resistance) so that on the occurrence of the latter signal all the information " bit " signals are simultaneously effective to produce the charge pattern (Fig. 2A, not shown). The Specification refers to known electrostatic techniques and discusses the optimum spacing between the web and the discharge electrodes and the optimum value for the discharge voltage. Specifications 696,515, 698,994 and U.S.A. Specifications 2,402,432, 2,791,949, 2,815,734 and 2,776,907 are referred to.
