Title: Yarn draw-texturing apparatus
IPC: D02G1/04
Filed: 1973-10-23
Abstract: 1422858 Draw-texturing yarns; roller arrangements TEIJIN Ltd 23 Oct 1973 [30 Oct 1972] 49280/73 Headings DID and D1F Apparatus for successively and/or simultaneously drawing and false-twist texturing or crimping continuously running, undrawn, filamentary, synthetic fibre yarns comprises, in the drawing zone, a reciprocating pin over which the yarn passes and a twist stop preventing run-back of twist upstream of the front drawing roller. In the operation of apparatus shown in Fig. 1, undrawn yarn Y1 from a package 1 (which may be one of several mounted in a creel truck in an upper part of the apparatus) is fed into a drawing zone by roller 3, pressed by a cot roller 2 also cooperating with a grooved guide 2', passes over and in contact with (at least one) reciprocating pin 4 and is then wound around draw roller 5 and separating roller 5'. The drawn yarn Y2 passes over and in contact with a grooved heater 6 whereby twists imparted by a frictional false-twisting bush 7 (or discs, ropes) are set and fixed, is wound around stretch roller 8 thence to take-up mechanism such as a ring-twister 9 (or a friction roller or drum or spindle winder). Yarn-breakage detector 31 actuates a cutter 32 to prevent supply of undrawn yarn. A polyurethane covered, pivotally mounted, spring-urged, manually releasable nip roller 11 presses against roller 5 and thus nips part of the turns of yarn thereon to prevent run-back of twist upstream thereof, Fig. 3 (not shown). An alternative twist-stop comprises a yarn tensioner disposed between roll 5 and heater 6. As shown in Fig. 2, the pin 4 is formed by an arm on a bar 13 slidably supported in a guide bracket 14 and pressed by spring 18 against a cam 16 mounted eccentrically on a shaft 15 which is rotated by a drive mechanism (not shown) to reciprocate the pin 4 e.g. 1-10 cycles per hour, in the direction of arrow A. The use of the apparatus is stated to reduce the short-term "flash" and non-uniformity of dyeability in fabrics knitted from the yarn product thereof.

Title: Data transfer and control apparatus
IPC: G06F3/09
Filed: 1974-11-15
Abstract: 1489230 Printers GENERAL ELECTRIC CO 15 Nov 1974 [26 Dec 1973] 49547/74 Heading G4H Apparatus adapted to receive data in a stream of pulse code groups at a first maximum rate and to deliver said code groups in intermittently-occurring continuous sequences for processing in serial manner at a second greater rate, comprises a plurality of code group storage registers smaller in number than the number of code groups in a continuously processed code group sequence, register control apparatus for progressing code groups through said registers which arrive during processing, and control apparatus responsive to the presence of stored code groups in all of said registers for delivering a signal adapted to initiate the operation of apparatus processing said code groups. A series of data, delete and control characters, each serial-by-bit, are each converted to parallel-by-bit form in a one-character shift register, then each passed through a series of first, second and third one-character storage registers to a printer. Here each data character is encoded as a matrix of dots and printed by a column of print wires on a print head which is advanced along the print line while a "print command" signal is present. Advance along the series of three storage registers is controlled by three "occupied" flip-flops, one associated with each register. If all the "occupied" flipflops are set (indicating their associated registers are occupied), an AND gate sets a "print command" flip-flop to produce the "print command" signal as its set output. Gates responsive to the outputs of the third storage register respond to any delete or control character therein to reset the "print command" flip-flop (thus stopping the print head) and to cause the printer to respond to the charcter in the third storage register to perform the required function. A 120 ms. timer is started by the set state of the third "occupied" flip-flop (provided the third storage register does not contain a delete or control character) and if the time period is allowed to elapse (i.e. without the timer being reset), then when it has elasped, the timer sets the "print command" flip-flop atain. The set state of the "print command" flip-flop resets the timer (as when the flip-flop is set by the AND gate). If neither the second nor the third "occupied" flip-flop is set, the "print command" flip-flop is reset. The printing rate exceeds the data reception by an average of 10%. The 120 ms. delay mentioned would be rather more than enough for reception of two characters in average operation, ie. to fill up the first and second storage registers as well as the third. A serial loop memory (shift register or delay line) may replace the sequence of three storage registers.

Abstract: 1,056,450. Photo-electric scanning systems. HOGAN FLAXIMILE CORPORATION. Dec. 19, 1963 [Jan. 8, 1963], No. 50266/63. Heading G1A. In a scanner for a facsimile transmitter or a densitometer, means are provided to convey a sample of light from the source to the image dissector to produce a white level pulse which is compared with an electrical reference signal, the overall sensitivity of the scanner being varied in dependence upon the comparison. Light from a lamp 10 Fig. 1 (not shown) illuminates the object 15 to be scanned and an image thereof is formed in the plane of a slit 20. The slit is scanned by a rotating spiral 21, and light passing therethrough falls on a photo-multiplier 25. An optical fibre 34 conveys light from the lamp direct to the plane of the slit 20 where it is scanned by the spiral 21. During the instant when the fibre 34 is being scanned, the signal from photo-multiplier 25 is gated by a commutator switch 30 to a control circuit. In the control circuit the signal is compared with a reference level set by a Zener diode, the current through which charges a capacitor which is discharged at a steady rate. The capacitor voltage controls the voltage applied to the photo-multiplier to compensate for variations in source output or detector sensitivity. In place of the optical fibre 34, an internally silvered light pipe, a system of mirrors or a direct path may be used.

Abstract: 1,244,358. Transformers. E. SCHEUBECK. 6 Nov., 1968 [6 Dec., 1967], No. 52540/68. Heading H1T. A three-phase on-load tap changing system for a transformer comprises rectifier bridges DB1, DB2, at least one load thyristor 29, load switches 1 to 6 and selector switches (7 to 12) for connecting the rectifier bridges to corresponding tapping positions. To effect a tap change from A1, A2, A3 to B1, B2, B3, bridge DB1 is connected to taps A1, A2, A3 and the load thyristor 29 triggered so that A1, A2, A3 are connected through DB1 to neutral point " Y "; load switches 1, 2, 3 are then opened. Connection is then made between the taps B1, B2, B3 through bridge DB2 by closing selectors 10, 11, 12 and triggering load thyristor 30. This causes a temporary short circuit between the two sets of tapping points, the short-circuit current being limited by chokes 31 and 32. Following this the thyristor 29 is blocked by means of a quenching circuit comprising an auxiliary thyristor 39, a capacitor 35 discharging through 29, and a choke 37. Selector switches 7, 8, 9 are then opened and load switches 4, 5, 6 are closed causing thyristor 20 to block since the current therethrough drops below its threshold value; selector switches 10 to 12 are then opened leaving the system on tapping points B1, B2, B3. A change of tapping position from B1, B2, B3 to A1, A2, A3 can likewise be effected wherein in the sequence thyristor 30 is first triggered, to block which its own quenching circuit may be used. Other arrangements (Figs. 2 and 3, not shown) with just one quenching circuit are described so that the quenching circuit can be connected across whichever load thyristor is ignited first. In one such arrangement, a second load thyristor and its associated choke and diode are replaced by a chatter-free switch (Fig. 4, not shown).
