Abstract: 1497967 Continuous tilting electric arc furnaces NATIONAL RESEARCH INSTITUTE FOR METALS SCIENCE & TECHNOLOGY AGENCY 16 March 1976 [17 March 1975 (4)] 10485/76 Heading F4B An oscillatable electric arc furnace for continuously melting directly reduced iron or iron ore comprises fixedly mounted electrodes 2 and a furnace body which oscillates about a vertical axis so that the molten material moves relative to the arc spots of the electrode tips to repeatedly alter their relative positions and achieve uniform heat distribution. The travel of a projecting tapping port 5 on the furnace body which has an adjacent lower tundish 6, being equal to or less than the maximum travel of the arc spots and melt. As shown the furnace body wall 1 is formed from two arcs of different radii of curvature and oscillates through an angle of 90 degrees. In a first modification (Fig. 2) the body is of rectangular or elliptical shape in horizontal section and is oscillatory along its major axis. In a further form (Fig. 3) the body is of annular shape formed by concentric inner and outer walls which oscillate about a vertical axis, the tapping port projecting inwardly from the inner wall. In a final embodiment, (Fig. 4) the body is an inverted rectangular pyramidal form oscillatable about a vertical axis through the apex.

Abstract: 1356371 Data communication systems SEARLE MEDIDATA Inc 7 March 1972 [8 March 1971] 10582/72 Heading G4H In a data communication system, Fig. 1, forty-eight stations 24 remote from a central processor 10, 12 by a link of significant communications delay (such as a telephone line) communicate with the system identically as local stations 16 operative in the system without delay, the remote stations communicating in threes with one of sixteen transponders 22 connected by sixteen lines 20 to a remote scanner 18 which is in turn connected, with the local stations, to a data transmission line 14. The system 10-16 may be a multi-phasic health screening system (Specification 1,267,825) and includes a scanner 10 which is the subject of Specification 1,313,063; this scanner provides a time slot for each station 16 for two-way data transfer, and two separated time slots for each station 24 for respective transmission and reception of data.  Scanner 18 and one transponder 22 are shown in outline in Fig. 3 and in detail in Figs. 4, 6, 7 (not shown); at the end of each line 20 is a modem and a pair of shift registers (thus there are actually sixteen modems and pairs of registers in scanner 18), data being transferred at high speed between scanner 10 and registers 28, 34, at low speed between scanner 18 and transponder 22, and again at high speed between registers 40, 44 and the three stations 42 on that line. For each line, data is sent in the form of three 24-bit words followed by three sync. bits; if these bits are found to be absent in transponder 22, then appropriate circuitry causes transmission of a row of zeros from transponder to scanner; a row of zeros followed by three new sync. bits (heralding fresh data) are sent back in return to the transponder, wherein detection of the bits causes data transfer to recommence. Appropriate counting, timing and control circuits are incorporated in scanners 10, 18 and in the transponders (each of which contains a phase lockloop (Fig. 7)) to ensure synchronism of operation. Scanner 18 includes test and monitoring equipment (70-75) for checking data on any telephone line or in any register, for calling for a test word from the scanner 10 switch register, and for measuring and adjusting transmission line delay; similar equipment is incorporated in the transponders 22.

IPC: D01H5/36
Filed: 1957-04-02
Abstract: 855,666. Spinning yarns; textile drafting rollers. HAYESHAW Ltd. Feb. 17, 1958 [April 2, 1957], No. 10725/57. Classes 120(2) and 120(3). A method of making a uniform yarn of components e.g. slivers or rovings which vary in thickness and are of different colour or dyeing affinity comprises feeding one component into the drafting stage at a varying rate, the rate of feed of the remaining components being varied in timed relationship so as to produce a yarn of uniform cross-section. The drafting frame comprises a pair of front nip rollers 1, 2 and two pairs of back nip rollers 3, 4 and 5, 6. The front rollers 1, 2 are driven from the shaft 25 through gear wheels 10, 11 and pinions 8, 9. A gap 14 in the toothing of a wheel 12 is of the same length as an arc of toothing 15 on a wheel 13. The pairs of rollers 3, 4 and 5, 6 are driven through pinions 16 and 18 from the wheels 12,13 respectively which are fixed to the shaft 25. Two rovings 20 of one colour, which pass between the rollers 3, 4 and a third roving 21 of different colour, which passes between the rollers 5, 6 are fed to the front rollers 1, 2, the roller 6 being stepped so that the rovings 20 are not nipped by the rollers 5, 6. Thin places are produced in the rovings 20 by the interruption of the drive of rollers 3, 4 caused by the gap 14. The rollers 5, 6 which rotate while the teeth of the arc 15 engage the pinion 18, feed the roving 21 intermittently to the rollers 1, 2. The resulting yarn is chiefly of the colour of the rovings 20 with short lengths of a mixture of the two colours spaced at intervals. Widely spaced teeth may be provided along the gap 14 and round the periphery of the wheel 13 excluding the arc 15 so that the roving 21 is not broken. The length of the gap 14 and arc 15 may be varied. The yarn may be used to produce warp tufted carpets, loom pile rugs or textile fabrics with longitudinally discontinuous patterns.

Abstract: 1489107 Sorting articles GEOSOURCE Inc 18 March 19.75 [29 March 1974] 11213/75 Heading G1A An apparatus for sorting articles according to light reflecting properties comprises viewing means 12 for sensing light energy reflected from an article 10, e.g. a coffee bean, to be sorted, the viewing means producing an electrical signal indicative of the light-reflective properties of the article, an amplifier 36 directly coupled to the viewing means for amplifying the electrical signal and preferably an ejector 50 operatively coupled to the amplifier for deflecting an article having predetermined lightreflective properties and responding to a corresponding amplified electrical signal. A normalizer 78 is operatively coupled to the amplifier 36 and  includes a reference for checking a predetermined signal as from a background 22 from the viewing means via the amplifier, a digital counter (140), Fig. 2 (not shown), for defining discrete stepwise signals corresponding to an error correction signal required for imbalance between the reference and predetermined signals and digital to analog converting means for introducing the output signals from the digital counter to the amplifier as corresponding analog signals. The error signal is introduced into the amplifier through a feedback loop 76. As shown the viewing means comprises a beam-splitter 14. light from which falls on a pair of filters 15, 16. Filtered light from each filter 15, 16 passes through an associated frame 17, 18 on to a respective photo-sensitive element 19, 20 e.g. a silicon solar cell. Each element 19, 20 is coupled to its own amplifier 36, 37. The signal from each amplifier, as well as being fed to its associated normalizer 78 is also fed to an inverter 38, 39 to produce a second signal for feeding into the normalizer. These two signals from each circuit are then fed to an electronic pattern 40 which, in turn, feeds four level discriminators 41-44 which control the actuation of the ejector 50. The apparatus is checked periodically for error by the closing of a switch, Fig. 3 (not shown), whereby both the object feeder and the ejector are immobilized. The check may also be instigated at will by the closure of a second switch (272, Fig. 3). There may be a delay introduced between the viewing of an object and the time of possible ejection of the same.
