Title: Improvements in and relating to resilient mountings suitable for toothed wheel transmission gearing
IPC: F16C27/02
Filed: 1922-12-18
Abstract: 214,298. Parsons, Sir C. A., and Cook, S. S. Dec. 18, 1922. Spring supports for bearings, of the intermediate shafts of double reduction gearing &c. The shaft or the like to be mounted is free to move in a direction transverse to its axis between fixed guides, resilient and damping means restraining such freedom in both directions. Flexible bars 12, Fig. 4, set transverse to the journal 1 and bushes 3 are pressed by adjustable springs 15 against the casing 5, the inner and outer rows engaging alternately. at their centres and ends with projections 20, 21 on the bearing 2 and casing 5, respectively. The bearing 2 is guided to slide vertically in the casing 5. Distance pieces 19 are also arranged between the layers alternately at the centres and ends so that adjacent bars alternately sag and hog, so as to rub together and provide a frictional damping effect. The individual bars of alternate pilas, may be arranged all to hog and all to sag, respectively. In a modification, the bars all engage the bearing 2 at their centres and the casing 5 at their ends and the piles are separated bv distance pieces. In a modification of this form, the bars in each horizontal layer are connected to form a flat solid plate, prevented from axial movement by angle irons. the springs and distance pieces being dispensed with. Engagement of the flat faces of the plates provides the frictional damping. In the form shown in Fig. 6, the bearings 2 are supported on levers 25 pivoted on the framing and connected by a yielding link 27. The link ends pass through guides 28, against which they are pressed laterally by spring action to provide the necessary friction, and engage telescopically against the action of a spring 29, which provides the flexible bearing support. The two bearings may also be interconnected by means ensuring the equality of their movement. Specification 22815/12 is referred to.

Title: A method of obtaining rolled alloyed steel products

Abstract: 895,067. Rolling. DEUTSCHE EDELSTAHLWERKE A.G. Oct. 14, 1959 [Oct. 18, 1958], No. 34855/59. Class 83 (4). In order to prevent alloy steel, more particularly ferritic chromium steel, from sticking to the rolls during hot rolling, the pickled plate is immersed in an oxidizing bath to form a coating consisting mainly of Fe 2 O 3 . The bath preferably comprises caustic soda with about 10% sodium nitrate and should be in a molten state at about 400‹ C. Up to 0.5% borax may be added. In an example, a pickled plate of ferritic chromium steel containing 17% chromium was immersed for about ten minutes and a velvety brown film containing 70% Fe 2 O 3  was formed. This film could be spread by rubbing or rolling. The melt was allowed to drip off the plate which was then rinsed in water, heated to rolling temperature and rolled at about 400 ‹ C. The oxide film formed a parting layer between the rolls and the steel and was readily removable after rolling.

Title: Improvements in or relating to the conversion of sound images into optical images
IPC: G10L21/06

Abstract: 801,294. Ultrasonic inspection devices. SMYTH, C. N. March 2, 1956 [Dec. 2, 1954], No. 34917/54. Class 118 (2). [Also in Group XL (a)] An arrangement for producing visible images of sound vibrations comprises a sound-electron current piezo-electric transducer 1, a conducting layer 2 in contact therewith on one side, a photo-sensitive layer 3 in contact therewith on the other side and optical means for scanning the layer 3 in synchronism with the scanning of a picture reproducer which obtains the light modulation from output signals derived from the photo-sensitive . layer. As shown, the transducer in the form of a crystal plate 1 is sealed as a window at the end of a vacuum tube T to whose metal cover 2 is sealed an oil- or water-filled tank for producing ultrasonic images of the required sound vibrations. The photo-electric layer 3 is scanned by light SP from a cathode-ray tube C and the electrons thereby produced flow to an open-mesh grid collector 4 in dependence on the potential difference between layer 1 and collector 4 and on the piezo-electric voltage. The load on resistance 5 is thereby used to modulate the beam of a cathode-ray tube receiver to give an optical picture of the sound image. The photoemissive layer may be a mosaic to which the electron charge is restored by electron bombardment from a photo or thermionic cathode 6 which is rendered negative to the layer 3 during the scanning light spot flyback time. Alternatively the layer 3 may be photo-conductive covered by a semi-transparent conducting film. Specification 477,139 is referred to.

Separation of readily freezable impurities, e.g. carbon dioxide and higher hydrocarbons from a gas mixture prior to liquefaction is effected by passing the crude mixture through layers 2, 8, 9, Fig. 3, of metal gauze in thermal contact with a plurality of vertical tubes 1 containing a boiling liquefied gas mixture which maintains the temperature of gauze layers at a constant level below the freezing point of the impurities but above the condensation temperature of any of the constituents of the purified gas mixture. The lower ends of tubes 1 open into a chamber 5, Fig. 1, which is connected to a constant level reservoir 7 of liquefied gas coolant which on entry into the lower portions of tubes 1 boils and occupies the whole height of the tubes and gains access to an upper open-topped vessel 12 from which vapour is discharged through a tube 14 together with purified gas mixture whilst liquid coolant is returned down end tubes 3, 4 to the chamber 5.

Abstract: 191,074. Prochazka, H. J., Prochazka, H. W., and Prochazka, D. R. Dec. 30, 1921, [Convention date]. Submarine vessels.-In submarine vessels in which arms carrying external articulated working- devices operated from inside the vessel pass through stuffing-boxes in the hull, entrance of water through the stuffing-boxes is prevented by flooding the boxes with a liquid which is automatically maintained at a pressure in excess of the surrounding water pressure. The tools are carried by shafts 2, 3 which pass through a stuffing-box 4 filled with oil and in communication through a duct 5 with the upper part of a cylinder 6 in which works a piston 7 acting in association with a larger piston 8 contained in a cylinder 9 in communication by way of the duct 15 with the outside water. This arrangement causes the oil in the cylinder 6 to be under the required excess pressure. When the piston 7 reaches its highest position, closure of an electric circuit causes a pump 11 to operate and return the piston 7 to its lowest position. In a modification a single cylinder is employed and the piston in addition to the water pressure, is acted upon by a constant force furnished either by a weight or spring. The invention is also applied to the closure of the entry for the power cable.
