Abstract: 884,607. Making finned tubing; rolling; riveting; soldering. CALUMET & HECLA Inc. April 16, 1959 [May 12, 1958], No. 12988/59. Classes 83 (2) and 83 (4). A metal tube 22, Fig. 4, comprises a cylindrical body having one portion of its external surface provided with at least one pair of ribs 23 integrally formed with the body, the ribs 23 being separated by a radial groove 24 having the base thereof lying either outside of or substantially coincident with the remainder of said surface of the body and a fin being received in each groove and clinched between the ribs defining the groove. The ribs 23 are formed by rolling discs 27, 28 while a disc 26 forms the groove 24, the space or groove 30 between each pair of ribs 23 is also formed by the disc 28, the width of which may be varied to suit the required spacing for pairs of ribs. Fins 15 are subsequently secured in the grooves 24 by clinching each pair of ribs 23 on to the base of each respective fin using rolling discs 32, 33 which are so shaped at their outer peripheries 35, 36 that the ribs 23 are set laterally to bend the base of the fin to provide an additional lock. Further methods for interlocking the ribs 23 and the attached fins include the use of tapered fins, indented fins, fins with holes at the inner periphery and fins with various enlargements of section at the base, the ribs being clinched into or about the various formations. Alternatively the fins may be secured by fusion in addition to the clinching of the ribs 23, a coating of fusion material being applied to the annular zone in the vicinity of the ribs 23 or a fusible wire being inserted beneath the fin in the groove 24. The ribs 23 may be arranged either as separate formations on the tube, as a helical formation or as longitudinal ribs. When separate formations are used the fins are slotted radially or formed with an additional enlarged eccentric aperture to permit assembly on the tube. The inside of the tube may be corrugated to facilitate bending of the tube.

Abstract: 809,299. Furnace electrodes. PECHINEY COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTROMETALLURGIQUES. April 27, 1956 [April 30, 1955], No. 13043/56. Class 39(3) [Also in Group XXXVI] A fused-electrolyte cell having one or more carbon blocks 4 forming its bottom part in which is embedded one or more horizontal steel conductor bars, has secured to one at least of the bars 5, beneath the electrolyte-containing part 13 of the interior of the cell, one or more metal sections having an electrical conductivity higher than that of steel, to reduce the total electrical resistance between the block or blocks 4 and an external conductor or conductors, 11 to which the bars 5 are connected, e.g. by aluminium connectors 10. The sections may comprise one or more copper strips welded to the bars 5, and may be perforated to ensure good connection between the copper and cast iron 8 which surrounds the bars 5 and strips 7 to seal them in grooves in the bottom face of the blocks 4. In a modification, Fig. 5, the metal sections are aluminium bars 10 secured to the bars 5 beneath the interior 13 of the cell which is reduced in width to protect the aluminium 10 from the heat of the cell. The copper strip or strips 7 may be retained, as shown, or omitted if the bars 5 are made thicker to protrude downwardly out of the grooves. In further modifications the ends of the bars 5 may be turned down to protrude vertically out of the cell bottom, or the bars 5 may have a pair of spaced, vertical limbs protruding downwardly intermediate the ends of the bars 5. Aluminium conectors 10 then extend laterally through brickwork 6 to each limb of the bars 5, or, where the ends of the bars 5 are downturned, short aluminium connectors 10 may join the limbs to bus bars 11 beneath the cell, which in both the further modifications is of unreduced width, as in Fig. 2. The down-bent bars 5 may be reinforced with a copper strip 7. Specification 663,763 is referred to.

Title: Improvements in and relating to the filling of bottles
IPC: B67C3/06
Filed: 1948-05-12
Abstract: 661,878. Botting. STALLER, J. May 12, 1948, No. 13063/48. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 5, 1948.] Class 125(ii). In a method of filling bottles in inverted positions with liquid under pressure with the use of a protective gas heavier than air, gas in the bottle forced out by incoming liquid is passed to a chamber from which the air content escapes into the atmosphere and the heavier protective gas is retained for re-use in the system. A bottle 1 is pressed in inverted position against a filling head 5 by a holder 3, with the end of one limb 10 of a movable U-tube within the filling head so that its lateral apertures 11 are closed and the other limb 12 extending through a cylinder 14 depending from superposed gas chambers 16, 17 supplied through an inlet 22 under about 2 atmos. pressure with protective gas of higher specific gravity than air. By admission of compressed air into cylinder 14 a piston 13 and with it the U-tube is raised until limb 10 reaches the bottom of the bottle. Pressure is thus equalized in the bottle, gas chambers and the gas space 24 of a liquid reservoir 6 communicating with chamber 16, so that on a valve 8 being opened liquid flows into the bottle and air, and later gas, is displaced into chamber 17, When the bottle is full valve 8 is closed, the U-tube retracted and the bottle removed, the internal pressure causing the internal ball 2 to seal the mouth. As the liquid level in reservoir 6 descends a valve 21 connected to a float 25 opens chamber 17 to the atmosphere, allowing air to escape and the pressure drop provides for inflow of liquid through an inlet 26. The U-tube is so dimensioned that the volume of the immersed portion with the bottle full is greater than the liquid content of both limbs so that this liquid is sucked into the bottle as the tube is withdrawn. Remaining traces are ejected through a blow-out valve 27 with the tube in its lowest position. Specification 658,613 is referred to.
