Title: Improvements relating to spinning, twisting and like textile machines
IPC: B65H57/20
Filed: 1953-12-04
Abstract: 745,959. Flyer for spinning yarns. FRANE, G. W. R. Dec. 2, 1954 [Dec. 4, 1953], No. 33759/53. Class 120 (2). A flyer having frictional means for resisting its rotation in taking yarn from the periphery of a bobbin or package by means of a guide at the extremity of the flyer is provided with additional guide means engaged by the yarn as it passes in a radial plane such that the two lengths of yarn adjacent the additional yarn guiding means form an obtuse angle with one another so that their relatively inclined tensional forces will produce a resultant action through the additional guide means in a direction tending to lift the flyer and thereby reduce the loading on the frictional means. In this way any increase in the tension in the yarn will tend to lift the flyer and reduce the drag thereon thus nullifying the increase in tension and tending to keep the tension approximately constant. As shown, the flyer is made in two parts a and b, each having an eye c at one end and spaced apart in the middle to engage in a groove e in a hub member d. The top surface of member d is adapted to receive one or more loading weights f and the lower face rests upon a leather or like friction washer g fitted on top of a flanged cap h at the upper end of a yarn package i. The additional guide means h are formed separately and brazed or welded on to the two parts a and b on either side of the centre of the flyer. The apparatus is shown used on a double twist spindle.

Abstract: 1358811 Colour television tubes RCA CORPORATION 21 July 1972 [22 July 1971] 34252/72 Heading H1D In a cathode ray tube having a display comprising a mosaic of discrete excited areas, the sizes of the areas are graded in a non-circular manner; this improves screen brightness and/or misregister tolerance compared with circular grading. In a shadow-mask tube with positive tolerance wherein the mask defines the areas of the luminous spots, the sizes of the apertures in the mask are graded non-circularly. In one example the contours of equal sized apertures are rectangular and run parallel to the edges of a rectangular display area; the sizes vary from 7.5 mils at the edges to 9 mils at the centre. In another example the contours are elliptical, and in a further example the contours are oval, being intermediate between ellipitcal and rectangular. In a black matrix tube with negative tolerance wherein the sizes of the luminous areas are determined by the sizes of the apertures in the matrix, the apertures may be graded in rectangular, elliptical or oval contours; in this case the shadow mask apertures may also be graded to balance the clipping and leaving tolerances and would not necessarily match the grading in the matrix.

Title: Improvements relating to thermionic amplifiers used in transmitting speech or like currents of varying frequencies
IPC: H03F3/02
Filed: 1920-12-06
Abstract: 154,925. Siemens & Halske Akt.-Ges. Dec. 5, 1919, [Convention date]. Thermionic relays.-In order to prevent the distortion of speech in passage through one or more amplifiers, arising from the selective magnifying action of those transformer circuits that have a natural frequency corresponding to the mean speech frequency, (a) damping resistances are inserted in those circuits, which bv acting with maximum damping effect upon the oscillations corresponding to the tuned frequency, tend to counterbalance the objectionable selective action; and (b) the natural frequency of such circuits is varied by inserting parallel condensers, so that instead of each circuit being tuned to the mean speech frequency, one circuit is tuned to the lower range, another to an intermediate range, and another to the higher range of the speech frequencies, the net result being to maintain the relative frequencies of the transmitted speech in their correct proportions, or if necesary to accentuate the higher or lower frequencies in order to obtain any particular tone colour desired. As shown in Fig. 4, resistances W1, W2 are connected in parallel to the secondary windings S1, S2 of the transformers U1, U2 for the purpose of damping the selectivity of these secondary circuits..Or a shunt circuit comprising resistance, inductance, and capacity in series may be employed. In order to vary or distribute the natural frequencies of the several circuits, capacities C1, C2, C3 are inserted in parallel as shown, their values being so chosen, for example, that the natural oscillations of S1, C1 is 3000, that of S2, C2 is 5000, whilst that of S3, C3 is 7000.
