Title: Method of intertwining a travelling multifilament, and multifilament thus intertwined
IPC: D02J1/08
Filed: 1969-07-10
Abstract: 1,223,650. Interlaced multifilament yarn. SOC. DE LA VISCOSE SUISSE. 10 July, 1969 [26 July, 1968; 7 Feb., 1969], No. 34904/ 69. Headings D1F and D1W. A method of intertwining the individual filaments of a travelling multifilament at intervals comprises passing the multifilament, under tension, through a zone where two freely issuing gas streams 8 meet, the gas streams impinging on one another from substantially opposite directions and being directed on to the multifilament substantially perpendicularly to the direction of travel thereof. The gas streams 8 issue from nozzles 12 the outlets of which may be tapered. The nozzles 12 are preferably placed 1-15 mm apart. The multifilament is passed through the said zone via thread guides 7, 9, and the tension is maintained in the range 0.03 to 0.2 gm/decitex. In a preferred embodiment, the multifilament is spun and stretched and is then intertwined as above in a relaxation zone before the multifilament is wound on a package 11 by means of a grooved roller 10. The intertwining is particularly applicable to polyamide or polyester filaments, but filaments of different compositions may be present in a single multifilament.

Title: High voltage power supply system for cathode ray tubes
IPC: H04N5/68
Filed: 1963-09-04
Abstract: 1,041,725. Cathode-ray tube protection circuits. SONY CORPORATION. Sept. 4, 1963, No. 34948/63. Heading H4T. [Also in Division H2] Damage to the screen of a chromatron type colour picture reproducing tube 15 (Fig. 1) due to an excessive potential difference between the metallic film electrode 22 backing the phosphorescent face 20 and the post deflection electrode 23 and caused by differences in the "warm-up" time of the separate E.H.T. circuits supplying these electrodes is prevented by arranging the warm-up times to be such that this potential difference never exceeds the steady state potential difference. This is achieved by utilizing an indirectly heated rectifier 50 (in a conventional " fly-back"  type E.H.T. generating circuit) to supply the electrode 22 and a directly heated rectifier 49 to supply the electrode 23 so that the latter reaches its operating potential (which is lower than that of electrode 22) before electrode 23 reaches its operating potential as shown by respective curves 62 and 63 (Fig. 3) and thus the excessive potential difference during warmup time, as shown by curve 26 (Fig. 3) in respect of prior art arrangements having respective warm-up characteristics as shown by respective curves 25, 24 is avoided.

The contacts are of molybdenum, tantalum or tungsten plated with gold, with an underplating of nickel if desired. An alloy of 80% by weight gold, 20% tin is used for solder. Silver wires are similarly soldered to contacts 48. The assembly is hard soldered to a threaded header 52 of copper, silver, brass, aluminium or ferrous alloy and encapsulated by welding on cap 64, 66 at 58 and crimping the wires into eyelets 68 in the insulating top 66 of the cap.

Abstract: 1486771 Television; telegraphy INDEPENDENT BROADCASTING AUTHORITY 29 July 1974 [30 July 1973] 36205/73 Headings H4F and H4P Groups of digital data for transmission, for example in one or two line periods of each field blanking period of a television signal, are each formed as shown in Fig. 7 in a form in which each "1" bit is represented by "10" and each "0" bit is represented by "01", each group being preceded by a run-in, synchronizing, signal, a start code in which there is at least one break from the above form of coding, and address signals. The digital data groups may represent alphanumeric characters for providing, on a television receiver, subtitles or a display instead of, or additional to, the television picture of, for example, the weather forecast. The display may be in colour or black-and-white. In the receiver each "10" and "01" code is split, the respective parts being fed into separate registers. If the contents of the registers for any alphanumeric character are not complementary a blank is displayed. Apparatus for generating the digital data includes a main store and a second store and connected thereto a punched tape reader, a keyboard, a digital clock, a printer and a visual display which may be used when altering the stored data. The transmitted data may be in the form of 50 "pages", 22 strips of alphanumeric characters per page, 40 alphanumeric characters per strip, each transmitted line period including, as the address signal, a data label, and page, strip and segment (4 per strip) numbers, followed by the signals representing ten alphanumeric characters. Each "page" is thus built up from the signals transmitted during 88 line periods. The second store includes a "queue" of at least one page as well as the page being transmitted. At a receiver, Fig. 4, the received television signal is fed to a video switch 3 directly, via a text adder, and via a data receiver, text signal generator and text signal video conversion unit. The text signal generator, which controls the text adder and the text signal video conversion unit, includes a character generator to which signals are repeatedly fed from a store and which produces signals to reproduce alphanumeric characters in a 7 x 5 matrix. Selection of input 1 to video switch 3 causes a conventional television display, selection of input 3 causes a display of only the alphanumeric characters. Selection of input 2 of video switch 3 causes display of both the television picture and the alphanumeric characters, whereas selection of both inputs 1 and 2 causes the display of both the television picture and the alphanumeric characters depending on which signal is instantaneously greater. A second television demodulator may be included so that alphanumeric information received on one television channel may be displayed on the television picture received on a different television channel.
