Title: Improvements in and relating to catamenial tampons
IPC: A61F13/20
Filed: 1954-02-12
Abstract: 767,022. Catamenial tampons. ROWLEY, H. E. G. (Fisher, D.). April 27, 1955.[Feb. 12, 1954], No. 4205/54. Class 81(2) A tampon is made from two or more flat webs, the direction of the fibres in one web being at an angle, which may be a right angle, to those of the adjacent web. In one form a broad outer web 17 of cotton fibre, having its fibres aligned with the arrows 18, is folded double and placed against an inner web 15, the fibres of which are in the direction of the arrow 16. The assembly is folded into U- shape and then compressed to form a cylindrical tampon. With the combination of longitudinally and transversely arranged fibres the absorption of the tampon is more uniform than hitherto.

When the required number of windings have been put into the hank, the reels A. B, are each rotated through 90 degrees, the movement of the forks leading the yarn through tying apparatus C, where the hank is tied, a knife severing the hank from feed yarn. Another hank is now wound upon the forks 11b, 16b (not shown). The next 90 degrees rotation of reels A, B, will bring the firstwound hanks to the transfer reel D, where narrow forks 50, 50a thereon, operated by racks and pinions, enter between the forks 11a, 16a and remove the wound and tied hanks from the reels A, B. The reel D is next rotated through 90 degrees to bring the hanks thereon to the two folding turrets E with which co-operate folding cranks 77 to fold the hanks to 1/3 of their original length. The folded hanks are then banded and removed from the machine, either manually or automatically. Specifications 661,468 and 4298/49 (as open to inspection under Sect. 91) are referred to.

Abstract: 689,525. Rotary-drum type regenerators. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. Feb. 28, 1951 [March 3, 1950], No. 4841/5. Class 64 (i) A rotary drum type regenerator in which the drum is divided by radial partition walls 10 into compartments each containing heat transfer material, is characterized in that the radial partition walls are provided with means to allow passage of a cooling medium in contact with said walls, the walls preferably being hollow so that the cooling medium may be passed therethrough. The cooling medium is preferably air which may be caused to pass through hollow spaces around the partition walls by the differences in pressure obtaining on the gas and air sides of the preheater as shown in Fig. 4 or it be circulated therethrough by a separate fan. In Fig. 4 a hollow space around each partition 10 is defined by walls 32 spaced from the partition and preferably carrying heat insulation 34. When the partition is passing from the air side to the gas side of the preheater, air which is at a relatively high pressure with respect to the gas, flows through the inlet 24 adjacent the lower end of the partition and through openings 28 in the upper part of the partition to the outlet 26 adjacent the lower end thereof thus cooling the partition 10. In Figs. 5 and 6 the cooling air is blown by a fan (not shown) through an annular chamber 36 to spaces between an annular plate member 46 and the rotor hub 42 and radially outwardly through the hollow spaces around or within each partition to a space defined by the regenerator casing and the outside of the rotor shell 16 from which it passes through openings 48 in one of the end plates of the casing to the outflow channel for heated air. A further partition construction comprises two spaced walls 54, 56 (Fig. 6) which may carry heat insulation 58. The rotor shell may also carry heat insulation. To further reduce distortion of the rotor, the rotor shell may be provided with slits extending axially inwardly Fig. 9 (not shown) and the radial partitions may be welded to the rotor shell along part of their length only, Fig. 8 (not shown).

Title: Improvements in or relating to sawtooth current wave generating circuit arrangements
IPC: H04N3/185
Filed: 1961-02-14
Abstract: 978,805. Valve sawtooth circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 14, 1961 [Feb. 17, 1960], No. 5453/61. Heading H3P. In a deflection circuit for a television display tube, the H.T. boosting capacitor is divided into two series-connected parts, the voltage across one part being used to control the deflection current amplitude. As shown in Fig. 3, a sawtooth current is generated in deflection coils 13 by valve 1 under control of waveform 2. The efficiency diode 11 provides a boosted H.T. voltage across capacitor 39 which, with capacitor 40, forms the flyback energy recovery circuit. Capacitors 39, 40 have comparatively low value so that parabolic voltages 41, 42 are provided by integration of the sawtooth current. Waveforms 41, 42 are added to the sawtooth current through the deflection coils 13 to provide the S-shaped waveform required for wide-angle cathode-ray tubes. The flyback voltage at point 21 is rectified by valve 19 to provide a negative bias for valve 1. Increase in sawtooth current amplitude will result in an increase in the amplitude of waveform 42 fed to the grid of valve 19 so that the rectified flyback voltage at the grid of valve 1 will become more negative thus correcting the increased amplitude. The E H.T. supply, obtained by rectifying the flyback voltage by means of a diode 30, is similarly stabilized. Valve 19 cathode voltage is stabilized by a neon tube 44. The capacitor 20 may alternatively be connected to point 14. In Fig. 5 (not shown) the neon tube 44 is replaced by a voltage-dependent resistor and the grid of valve 19 is fed via a blocking capacitor. Reducing radiation.-Windings 37, 38 form a push-pull circuit to minimize radiation from the deflection circuit. Winding 38 may be omitted if this feature is not required. Specifications 849,980 and 898,625 are referred to.
