Filed: 1952-10-08
Abstract: 736,808. Torsional-vibration dampers. CROSET, L. P. Oct. 7, 1953 [Oct. 8, 1952; March 25, 1953], Nos. 25181/52 and 8161/53. Class 108 (3). A vibration damper for rotary shafts comprises a casing A formed by two portions 12, 13 (Fig. 1) united by two submerged circular butt welds 14, 15, an annular flywheel 11 being located in the casing which is filled with a silicone damping fluid, the casing having a reservoir 13g associated therewith and formed at least partially within a part of one of the portions 12, 13 which is nearer to the centre of rotation of the damper than the inner periphery of the flywheel. In Fig. 1, the reservoir 13g is formed by a groove turned in the casing, and it is connected by a restricted passage or passages 13m with the interior of the casing A. The reservoir 13g may however open directly into the casing A (Figs. 2 and 4, not shown). The member 13 has an inwardly directed mounting flange 13i. Lips of a thickness of a quarter to a third of the thickness of the radial portions of the members 12, 13, are formed on the member 12, at 12a, and on the member 13, at 13a. These lips distort during welding and prevent distortion of the operative part of the casing A. In a modification (Fig. 2, not shown), the outer face of the flange 13i, is coplanar with the outer axial face of the member 12. The lip 13a is then provided by turning a groove in the outer face of the flange 13i. The member 12 may be an annular disc (Fig. 4, not shown) which closes an annular cavity of channelshaped cross section provided by the member 13. A filling aperture 17 is provided at diametrically opposed positions (one only shown in Fig. 1). The aperture is sealed by welding 18. The flywheel 11 has bearing engagement at its inner periphery 11i, and at axially-projecting annular portions 11f. In the construction shown in Fig. 6, the bearing engagement is provided by bronze rings 16 rigid with the flywheel. The reservoir is provided at 13g, and a small volume is provided by the centre portion 11c of the inner periphery of the flywheel 11 being disposed slightly radially outwards of the bearing surfaces of the rings 16. A circumferential groove 11g, 16g is formed in the axial face of the flywheel 11 at the junction of each of the rings 16 and the flywheel 11 (Fig. 7). This groove is connected by peripherally-spaced radial grooves 16h with grooves 16k axially disposed in the peripheral bearing surfaces of the rings 16. These grooves are shaped to assist the drainage of salts when the flywheel 11 is lifted from an electrolytic zinc-plating bath. All the working surfaces of the casing A are also zinc plated. The casing may alternatively be secured together by nuts and bolts. The flywheel may be forged, flame cut, rolled, or centrifugally cast. The casing components may be steel pressings, stampings, or drop forgings, or may be steel or whitehart malleable iron, castings. For non-magnetic dampers, the flywheel may be of bronze, and the casing of aluminium. Specification 636,881 is referred to.

[Class 37] [See also Group XL] Damping is reduced and rendered substantially constant at a small positive value in a two or four terminal network or amplifier by the provision of a feed-back path including an element such as a " hot conductor " the attenuation of which varies with amplitude at a rate so low as to give no appreciable change during a cycle of the lowest operating frequency. The arrangement is such that at an auxiliary frequency outside the operating range self-oscillation occurs at constant amplitude. Fig. 2 shows an amplifier V the backcoupling path of which includes a hot cathode conductor H in series with a resistance VW and a network D having a constant attenuation over the working range and a reduced attenuation at a frequency outside the range at which frequency self oscillation occurs. A filter S may be provided to remove the frequency at which self oscillation occurs from the output. Fig. 6 shows an arrangement for increasing the output of an amplifier by partially compensating for its internal impedance Ri when connected in parallel with a load Vb by a negative resistance NW and an amplitude dependant potentiometer H, VW. Oscillation occurs at a frequency outside the operating range determined by the combination S which is shunted by an ohmic resistance W. The apparatus may be used for determining or measuring noise. The resistance of the potential divider remains constant so that the amount by which the oscillatory current diminishes when the noise is added is a measure of the noise and may be determined by measuring the oscillatory current in the back coupling path.

Abstract: 485,264. Electron-microscopy; cathoderay tubes. ZEISS IKON AKT.-GES. Sept. 22, 1937, No. 25732. Convention date, Oct. 2, 1936. [Classes 39 (i) and 40 (iii)] For microscopically examining objects by means of electron-discharge apparatus, an image of the object is produced on a photocathode by means of short-wave radiation, and this image is magnified electron-optically. With the apparatus shown in Fig. 1, the object 1 is illuminated with ultra-violet light from a mercury lamp 3, and an image is formed by an optical system 4 on a photo-cathode 5 on the inner side of a quartz window 6, at one end of an electron-discharge tube 11. Magnetic lenses 7, 8 cause the emitted electrons to produce a magnified image of the object on a fluorescent screen 9 on a transparent plate at the other end of the tube 11. A potential difference of about 50,000 volts exists between the cathode 5 and the anode 12 on the inside of the tube. In the arrangement shown in Fig. 2, the object 22 is illuminated with rays produced by an X-ray tube 20, and an image is projected by the X-rays on to a thin metal window 23 in a vacuum tube 25. The electrons liberated at the window are concentrated by magnetic lenses 27, 28 on to a cathode 29 comprising a mosaic plate in the form of a subdivided metal layer. The charge image produced at the cathode is scanned by an oscillating electron beam 30 which is utilized, as in known television apparatus, to control an electron beam in a cathode-ray receiver of the Braun tube type, and thereby to produce a magnified image of the object on the fluorescent screen or equivalent device in the Braun tube. Fig. 3 (not shown) illustrates diagrammatically the means for coupling the scanning-device shown in Fig. 2 to the cathoderay receiver.
