Abstract: 1,105,885. Absorbent tampon or pessary. G. DE CRESCENZO. 24 Aug., 1966 [14 Sept., 1965], No. 37953/66. Heading A5R. An absorbent tampon or pessary comprises a body of expanded synthetic resin having a passage therethrough, a rubber ring connected to the resin body by a cord in the form of an endless loop passing through the passage in the resin body, and a thimble-shaped gelatin capsule having a volume less than that of the uncompressed resin body but being intended to contain the resin body when the body is compressed. The tampon or pessary also may comprise a rubber container open at one end, of a size to contain the uncompressed resin body and formed with at least one aperture, the or each aperture being in alignment with the passage through the resin body. As illustrated in Figure 1, a cylindrical body 1 of expanded synthetic resin, formed with an axial passage 2, is enclosed in a cylindrical rubber container 3 having one end open and the other end closed by a base 4 at the centre of which is an aperture 5 bounded by a tubular projection 6. A silk cord 7 passes through the aperture in the container and the aligned passage in the resin body, over the exposed end surface of the resin body and over the arcuate wall surface of the container to form a loop 8 to which a rubber extracting ring 9 is attached. To complete the tampon or pessary, the assembly of resin body and container is rolled up and then is placed within a gelatin capsule (not shown) having a cap which faces that end surface of the resin body which is not covered by the container. In a modification illustrated in Figure 4 (not shown), the passage formed in the cylindrical resin body is a transverse passage, the arcuate wall surface of the container having formed therein two opposed apertures each of which is aligned with one end of the passage through the resin body. Instead of the rubber container, the cylindrical resin body may have a rubber sheet adhered either to one end surface thereof, as illustrated in Figure 5 (not shown), or to one end surface and the arcuate wall surface thereof, as illustrated in Figure 6 (not shown), the passage formed in the resin body being a transverse passage in both these embodiments; if desired, the sheet may cover only part of the arcuate wall surface of the resin body. The rubber sheet is produced by immersion of the resin body or a part thereof in rubber latex or in rubber solution. The resin body may be made of polyurethane resin. The gelatin capsule, which dissolves when the tampon or pessary is in use, may have a height less than the length of the resin body. The tampon or pessary may be used as either a catamenial or a contraceptive device.

IPC: H05B41/30
Filed: 1968-08-08
Abstract: 1,213,386. Testing batteries. WARWICK ELECTRONICS Inc. Aug. 8, 1968 [Aug. 8, 1967 (2)], No. 37960/68. Heading G1U. A battery condition indicator comprises a lightemitting device, e.g. neon 20, which, provided the battery voltage is above a certain minimum, flickers at a rate dependant on the battery voltage. In Fig. 1 an oscillator 12 is energized by the battery 10 and thus supplies oscillations whose magnitude is proportional to the battery voltage. These oscillations are stepped-up by transformer 23, rectified by diode 13 and used to charge a capacitor 17 through resistors 15, 16. When the capacitor voltage reaches the ignition voltage of neon lamp 20 the latter momentarily lights and discharges the capacitor, which starts to charge again, repeating the cycle. The lamp thus flickers at a rate dependant on the time taken to charge the capacitor, which in turn is dependant on the battery voltage. By adjusting resistor 15 the lamp is made to appear, to the human eye, continuously energized when the battery is fresh. As the voltage drops the flicker becomes more noticeable, the rate of the flicker decreasing until the voltage is so low that the lamp cannot light at all.

Abstract: 867,700. Magnetic amplifiers. COMPAGNIE INDUSTRIELLE DES TELEPHONES. Dec. 9, 1957 [Dec. 21, 1956], No. 38215/57. Class 40 (9). Bias to a winding Ep of a self-excited transductor B is just sufficient to set B to its residual current state when it is supplied by quiescent current from a self-excited transductor A with a feed-back winding ecr. The arrangement is such that the change in quiescent current from A compensates for the change in the residual point of transductor B in the face of temperature variations. Both transductors are in any event enclosed in a thermostatically regulated space. The transductors are energized from the same source U and the cores are identical. The feed-back winding ecr and bias winding Ep have the same number of turns. A continual bias Uc may be applied to transductor A causing B to operate on the unsaturated side of its residual current point and the bias may be selectively applied to B to switch B to saturation regardless of variations of control voltage.

Filed: 1956-12-19
Abstract: 856,185. Optical and electrical sensing. BALDWIN PIANO CO. Dec. 19, 1956, No. 38711/56. Class 40 (2). [Also in Groups XXXV and XL (b)] Disc records, carrying concentric rings of periodically-related digital patterns are produced on photographic plates 45 by means associated with photo-electrically sensed master patterns on a reference disc 15 and frequency. dividing circuits comprising flip-flops 21 ... 37. Opaque and transparent tracks on the revolving disc 15 when aligned with the pattern of a grating 18 are detected by light from a lamp 17 falling on the photo-cell 16, pulses from which control flip-flop circuits 21 ... 37. To maintain spaced phase relationship between successively recorded tracks, another photo-cell 38 initiates reset signals at every revolution of the disc 15 to throw switches 82-S16 in accordance with the pattern to be produced on the plate 45. The flip-flop circuits are selected by a switch S17 to control a waveshaper and amplifier 46 which causes " Duralumin " (Registered Trade Mark) ribbons A and B in the field of a permanent magnet to move when a current is passed through them so as to modulate the light from a source 51 falling on to the photographic plate 45. A prism 53 provides a visual check. The speed of the turntable 12 is controlled retroactively by supplying part of the output of the photo-cell 16 to a discriminator 56 which regulates the speed of the motor 14. For the generation of sine function codes the grating 18 (indicated as 68 in Fig. 5, not shown) is mounted on ballbearings and revolved by gear chain in the same direction and relative speed as the plate 15. To obtain a reference pulse at two positions during each revolution a reflector is fitted to the underside of the disc and two lamps and photo-cells arranged to co-operate with it at two positions (Fig. 8, not shown, refers). The combined photo-cell output may be fed to a single limiter to produce steep fronted waves and the accuracy of the plate improved by making a plate using two photo-cells spaced 180 degrees apart, then making a further plate therefrom with the photo-cells at half the previous angle and so on.
