Title: Improvements in machines for spinning, doubling, twisting and the like, yarns, fibres, and the like
IPC: D01H1/10
Filed: 1929-05-21
Abstract: 338,606. Dunlop Cotton Mills, Ltd., Andrew, T. E., and Langstreth, M. May 21, 1929. Divided on 338,570. Spindle apparatus; special yarns, producing; winding-machines. - In apparatus in which the yarn is withdrawn in the form of a loop from a rotating bobbin mounted on a fixed spindle so that two twists are imparted thereto for each revolution of the apparatus, the whole of, or the main part of, the tensioning of the yarn is effected by the weight of the bobbin operating through a drag washer interposed between the bobbin and its support. Provision may be made to adjust or control the tension so that it remains constant during the unwinding of the bobbin, and so that it may be predetermined to suit any specified conditions. The bobbin 2, Fig. 1, rotates about a tubular spigot 3. carried by a bobbin support 4, mounted on ball bearings 29 on a spindle 1 driven by a pulley 35. The yarn passes from the bobbin through a central hole in the spindle 1, and through a hole in a rotating disc 33 to the outer edge of the same and thence to take up point 38. Ballooning is controlled by a ring 36 and a ring 37 is provided to hold the yarn clear of the bobbin when setting-up. The bobbin 2 is wound on a tube 10 keyed to a sleeve 5 rotatable on the spigot 3 and carrying a flange 6 seated on a washer 7 on the platform 8. The washer is fixed to the platform or the platform is roughened to prevent rotation. The platform 8 is floatably mounted on the support 4 as by sitting on a spherical seat 11. A peg 12 prevents rotation of the platform. To maintain an even tension during the unwinding of a bobbin, the bobbin may be wound so that the weight, of the package 13, Fig. 3, considered as a function of its diameter decreases at such a rate that the ratio of the radius of the bobbin to the weight of the yarn and the spool remains constant; or the density of the spool may vary as unwinding proceeds by employing a traverse in winding varying between close and open; or the weight may be increased at the required rate by dropping water into a reservoir as the weight of yarn decreases; or a collapsable drag washer may be employed. To suit the tension to particular conditions the effective diameter of the washer and the material of which it is made may be varied. This arrangement of spindle may be used to pass the twisted yarn to a ring doubling-spindle, or a number of yarns may be twisted one round another to produce fancy effects, the tension, counts &c. of the different yarns being arranged to give the required results. It may also be used to wrap an outer filament round a central core so as to provide insulation on a wire, as shown in Fig. 7. The bobbin support may be of the kind described in Specification 338,570.

Title: Improvements in or relating to yarns and fabrics
Inventor: LODGE REGINALD MONTAGUE
IPC: D02G3/32
Filed: 1963-03-07
Abstract: A composite yarn comprises (a) one or more elastomeric, synthetic, continuous filaments (or yarns thereof) having a degree of reversible extensibility of over 100% doubled with (b) one or more crimped, non-elastomeric, synthetic continuous filaments (or yarns thereof) possessing extensibility at break (measured along the filamentary axis) of less than 50%.  When the filaments are doubled, the respective tensions are such that the crimps in filaments (b) are straightened (and the filaments may even be slightly extended) and filaments (a) are extended or stretched sufficiently to ensure that filaments (b) assume the full crimp when the composite yarn is relaxed and allowed to contract, although they are not stretched to such an extent that such contraction would form loose convolutions in filaments (b). Filaments (a) may be of N-alkoxymethylpolyamides, butadiene/styrene or acrylonitrile or 2-vinylpyridine copolymers, polychlorobutadiene, polyether or polyester-urethanes, polyisobutylene, N-alkyl-copolyamides, copolyesters from aliphatic and aromatic dicarboxylic acids: filaments (b) may be of polyacrylonitrile, copolymers of acrylonitrile and vinyl pyridine, poly-epsilon-caprolactam, polyhexamethylene adipamide or sebacamide, polyethylene terephthalate, polypropylene, cellulose triacetate and crimped by edge, false-twist or stuffer-box crimping.  The composite yarn may be knitted, warp-knitted or woven into fabric e.g. as elastic weft with cellulose acetate warp yarn of lower denier and twist.

Title: Base level stabilizing circuits
IPC: H04N5/16
Filed: 1964-03-05
Abstract: 1,021,904. Automatic character reading. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 5, 1964 [March 14, 1963], No. 9281/64. Heading G4R. [Also in Division H4]  The invention relates to circuits for stabilizing the base level of an input signal having a varying or wandering base line. The incoming data signal, e.g. a video signal, including spiked noise components and having a wandering base line, Fig. 3 (not shown), is superimposed in mixer 2, Fig. 1, on a sawtooth waveform having a slope such that the direction of the wandering base line of the signal is always downward, Fig. 2 (not shown). The output of mixer 2 passes through capacitor 5 to junction 6 where diode 7 clamps the waveform so that it can never exceed + V 1  and diode 8 conducts any time the signal goes below ground such that junction 6 never goes negative and this flattens out the base line, waveform 3A. Diode 7 connected to the positive potential allows the capacitor 5 to be recharged by a positive blanking pulse occurring in the video signal at the end of each sweep time. The information pulses contained in the video signal are transmitted by capacitor 5 although junction 6 can never go below ground. Waveform 3A then passes through negative clipper 10 which clips the lowamplitude noise out of the signal to provide the waveform 3B. This signal then passes through capacitor 12 and double-ended clamp 13 which detects the small pulses located on pedestals and produces waveform 3C. The data signal may comprise the output signal of flying spot scanner, the pulse width of the sawtooth waveforms being equal to one scan of the flying spot scanner, and waveform 3C provides information relating to marks narrower than the scanning spot width of the flying spot scanner which would have otherwise been lost. A more detailed system is described in the Specification with reference to Fig. 4, not shown.
